AnyConnect 4.4.03034 is a maintenance release that includes the following enhancements and features and that resolves the defects described in. • Network Visibility Module (NVM) is now supported on Linux, but before using it, you must set up a kernel driver framework. You can choose to prebuild an AnyConnect Kernel Module or build the driver on target.

Whether the kernel module is prebuilt or for on target, you must prepare the target device in the following way: • Make sure that the GNU Make Utility is installed. • Install the kernel header package: For RHEL, install the package kernel-devel-$(uname -r), such as kernel-devel-2.6.32-642.13.1.el6.x86_64. For Ubuntu, install the package linux-headers-$(uname -r), such as linux-headers-4.2.0-27-generic. • Make sure that the GCC compiler is installed.

The major.minor version of the installed GCC compiler should match the GCC version with which the kernel was built. You can verify this in the /proc/version file. Refer to the AnyConnect Administrator Guide for additional information:. • Captive portal detection and trusted network detection are now supported on Linux operating systems.

• With this AnyConnect 4.4.03034 release, LittleSnitch is now compatible with NVM on Mac OS X. AnyConnect 4.4.01054 is a maintenance release that includes the following features and enhancements and that resolves the defects described in. • Enhancements to ISE Posture Note ISE 2.2 (or later) is required for functionality of these ISE Posture features. Refer to the for additional details about ISE configuration. • Stealth Agent for posture— (Windows and Mac only) Allows ISE Posture to run as a hidden service within AnyConnect Ul.

For example, AnyConnect Stealth posture agent hides the system scan tile and notification from the end user client. • Continuous endpoint monitoring—Monitors installed and running applications to ensure that dynamic changes are observed on the endpoint. • Next-generation provisioning and discovery—Provides additional non-URL redirect based options to deploy AnyConnect software from ISE, as well as additional resiliency in AnyConnect to ISE communication, including the ability to support compliance flows with third-party network infrastructure. • Application kill and uninstall capabilities—Provides the ability to take policy action against select applications or to reduce software license consumption. • Endpoint context visibility—Adds a unique identifier (UDID) to identify a specific endpoint rather than to solely rely on a MAC addresses. • Additional context checks—(Windows and Mac only) Checks for third party and native OS firewall state, as well as automated remediation • Brand name changes related to OpenDNS Umbrella.

Some examples include the following: • OpenDNS Umbrella is now Cisco Umbrella • OpenDNS Global Network is now Cisco Umbrella Global Network • Umbrella Virtual Appliance is now Cisco Umbrella Virtual Appliance • OpenDNS Umbrella Roaming Client is now Cisco Umbrella Roaming Client. AnyConnect 4.4.00243 is a major release that includes the following features and enhancements and that resolves the defects described in. • SAML 2.0 SSO (integrated with ASA release 9.7.1)—Support for a greater set of web-based authentication through SAML. You can use SAML for initial single-signon (SSO) session authentication. During a reconnect, AnyConnect intentionally does not go through the SAML process again, as it would be disruptive to a seamless reconnect. Additionally, if the user logs out of the IdP using a browser, the AnyConnect session remains. You must have an Apex license to use the SAML feature.

• Multiple certificate authentication (integrated with ASA release 9.7.1)—Windows provides certificate stores for AnyConnect to use in the VPN client profile. You can now have multiple certificate authentication combinations and can configure the secure gateway to dictate to the client which one of the multiple certificate authentication choices is acceptable for a particular VPN connection. • Increased security for connection timeouts—Using the vpn-session-timeout and vpn-session-timeout alert-interval settings in ASA, the end user of the AnyConnect Secure Mobility Client receives session expiration notices as to when session limits are exceeded. The UI displays a 'Your connection will soon exceed the session time limit.

A new connection will be necessary' message so that they can rectify the situation without being logged out of VPN. Refer to the Specify the Maximum VPN Connection Time in Group Policy section here: for further information on adjusting these settings.

Note You may need to enable Show Connection Notices as an AnyConnect preference to see these alerts. • Control of DHCP server route—On Windows, by setting a group policy custom attribute, you can control the creation of the DHCP public server route. The no-dhcp-server-route custom attribute must be present and set to true to avoid creating the public DHCP server route upon tunnel establishment.

• Further IPv6 implementation—IPv6 connections are stable on a single or dual stack network, and the user can control the primary and secondary IP protocols used for the connection. When migrating between IPv6 to IPv4 or vice versa, the reconnect is seamless, and fallback should happen between the two protocols if a tunnel connection is broken. Support for IKEv2 tunnels for IPv6 was added. • Network Visibility Module enhancements— • Broader data collection offering the addition of hashing for anonymization rather than just excluding them altogether • Support for Java as a container on Windows, Windows 64-bit, and Mac OS X • Configuration of cache to set maximum size and duration • Periodic flow reporting to keep track of flows (such as server connections or downloads) at the interval you configure • Signing verification update for Windows—Only transforms provided by Cisco can be applied to ASA or ISE. Customer-provided transforms (those not signed by Cisco) will not work. You can apply your own transforms through the out-of-band methods. Additional Bug Fixes Related to Umbrella Roaming Security Plugin • If registration fails, the plugin could apply DNS protection without the correct policy.

• (Windows 10 Only) Network adapters are not returned from the system in the correct priority order. • Support for cloud API scalability to reduce load from Umbrella Roaming plugin on the Umbrella backend cloud infrastructure Note We are investigating a scenario where the domain search suffix may not be properly pulled by the Umbrella Roaming plugin, resulting in local domain resolution issues. Mac OS X Fixes • (CSCvb49067) Umbrella protection state should be open on IPv6 networks • Error retrieving the endpoint hostname during Umbrella plugin registration • Support for cloud API scalability to reduce load from Umbrella Roaming plugin on the Umbrella backend cloud infrastructure. Coexistence of ISE and ASA Headends • If you are using both ISE and ASA for client posture, the profiles must match on both headends.

• AnyConnect ignores the ISE 1.3 server if NAC Agent is provisioned for the endpoint. • If the Cisco NAC agent and the VPN Posture (HostScan) module are both installed on a client, the Cisco NAC agent must be at least version 4.9.4.3 or later to prevent posture conflicts. • The NAC Agent ignores the ISE 1.3 server if AnyConnect is provisioned for the endpoint in ISE.

Minimum ASA/ASDM Release Requirements for Specified Features • You must upgrade to ASDM 7.5.1 to use NVM. • You must upgrade to ASDM 7.4.2 to use AMP Enabler. • You must upgrade to ASA 9.3(2) to use TLS 1.2. • You must upgrade to ASA 9.2(1) if you want to use the following features: • ISE Posture over VPN • ISE Deployment of AnyConnect 4.x • Change of Authorization (CoA) on ASA is supported from this version onwards • You must upgrade to ASA 9.0 if you want to use the following features: • IPv6 support • Cisco Next Generation Encryption “Suite-B” security • AnyConnect client deferred upgrades • You must use ASA 8.4(1) or later if you want to do the following: • Use IKEv2. • Use the ASDM to edit non-VPN client profiles (such as Network Access Manager, Web Security, or Telemetry). • Use the services supported by a Cisco IronPort Web Security Appliance.

These services let you enforce acceptable use policies and protect endpoints from websites found to be unsafe, by granting or denying all HTTP and HTTPS requests. Suono Telefono Libero Login. • Deploy firewall rules. If you deploy always-on VPN, you might want to enable split tunneling and configure firewall rules to restrict network access to local printing and tethered mobile devices. • Configure dynamic access policies or group policies to exempt qualified VPN users from an always-on VPN deployment. • Configure dynamic access policies to display a message on the AnyConnect GUI when an AnyConnect session is in quarantine.

ASA Memory Requirements Caution The minimum flash memory recommended for all ASA 5500 models using AnyConnect 4.0 or later is 512MB. This will allow hosting of multiple endpoint operating systems, and logging and debugging to be enabled on the ASA. Due to flash size limitations on the ASA 5505 (maximum of 128 MB), not all permutations of the AnyConnect package will be able to be loaded onto this model. To successfully load AnyConnect, you will need to reduce the size of your packages (i.e. Fewer OSs, no host Scan, etc,) until they fit on the available flash.

Check for the available space before proceeding with the AnyConnect install or upgrade. You can use one of the following methods to do so: • CLI—Enter the show memory command. Asa3# show memory Free memory: 304701712 bytes (57%) Used memory: 232169200 bytes (43%) ------------- ---------------- Total memory: 536870912 bytes (100%) • ASDM—Choose Tools >File Management. The File Management window displays flash space. If your ASA has only the default internal flash memory size or the default DRAM size (for cache memory), you could have problems storing and loading multiple AnyConnect client packages on the ASA. Even if you have enough space on the flash to hold the package files, the ASA could run out of cache memory when it unzips and loads the client images.

For additional information about the ASA memory requirements and upgrading ASA memory, see the. The VPN Posture (HostScan) Module provides the Cisco AnyConnect Secure Mobility Client the ability to identify the operating system, antivirus, antispyware, and firewall software installed on the host to the ASA. The VPN Posture (HostScan) Module requires Hostscan to gather this information.

Hostscan, available as its own software package, is periodically updated with new operating system, antivirus, antispyware, and firewall software information. The usual recommendation is to run the most recent version of HostScan (which is the same as the version of AnyConnect).

AnyConnect 4.4.x is incompatible with HostScan releases prior to HostScan 4.3.05017. AnyConnect 4.4.x is however backwards compatible with HostScan 4.3.05017, and you must use HostScan 4.3.05017 (or later HostScan 4.3.x releases) as the HostScan image in ASDM (Configuration >Remote Access VPN >Secure Desktop Manager >Host Scan image). The is available on cisco.com. The support charts opens most easily using a Firefox browser. If you are using Internet Explorer, download the file to your computer and change the file extension from.zip to.xlsm.

You can open the file in Microsoft Excel, Microsoft Excel viewer, or Open Office. Note AnyConnect will not establish a VPN connection when used with an incompatible version of HostScan.

Also, Cisco does not recommend the combined use of HostScan and ISE posture. Unexpected results occur when the two different posture agents are run.

The ISE Posture compliance module contains the list of supported antivirus, antispyware, and firewall for ISE posture. While the HostScan list organized by vendor, the ISE posture list organizes by product type. When the version number on the headend (ISE or ASA) is greater than the version on the endpoint, the OPSWAT gets updated. These upgrades are mandatory and happen automatically without end user intervention. The individual files within the library (a zip file) are digitally signed by OPSWAT, Inc., and the library itself is packaged as a single, self-extracting executable which is code signed by a Cisco certificate.

You can view the charts using Microsoft Excel, Microsoft Excel Viewer, or OpenOffice at this location:. Cisco supports AnyConnect VPN access to IOS Release 15.1(2)T functioning as the secure gateway; however, IOS Release 15.1(2)T does not currently support the following AnyConnect features: • Post Log-in Always-on VPN • Connect Failure Policy • Client Firewall providing Local Printer and Tethered Device access • Optimal Gateway Selection • Quarantine • AnyConnect Profile Editor For additional limitations of IOS support for AnyConnect VPN, please see.

• Microsoft Installer, version 3.1. • Upgrading to Windows 8.1 from any previous Windows release requires you to uninstall AnyConnect, and reinstall it after your Windows upgrade is complete. • Upgrading from Windows XP to any later Windows release requires a clean install since the Cisco AnyConnect Virtual Adapter is not preserved during the upgrade. Manually uninstall AnyConnect, upgrade Windows, then reinstall AnyConnect manually or via WebLaunch.

• To start AnyConnect with WebLaunch, you must use the 32-bit version of Firefox 3.0+ and enable ActiveX or install Sun JRE 1.4+. • ASDM version 7.02 or higher is required when using Windows 8 or 8.1. Windows Limitations • AnyConnect is not supported on Windows RT.

There are no APIs provided in the operating system to implement this functionality. Cisco has an open request with Microsoft on this topic.

Those who want this functionality should contact Microsoft to express their interest. • Other third-party product’s incompatibility with Windows 8 prevent AnyConnect from establishing a VPN connection over wireless networks. Here are two examples of this problem: • WinPcap service “Remote Packet Capture Protocol v.0 (experimental)” distributed with Wireshark.

To work around this problem, uninstall Wireshark or disable the WinPcap service, reboot your Windows 8 computer, and attempt the AnyConnect connection again. • Outdated wireless cards or wireless card drivers that do not support Windows 8 prevent AnyConnect from establishing a VPN connection. To work around this problem, make sure you have the latest wireless network cards or drivers that support Windows 8 installed on your Windows 8 computer.

• AnyConnect is not integrated with the new UI framework, known as the Metro design language, that is deployed on Windows 8; however, AnyConnect does run on Windows 8 in desktop mode. • HP Protect tools do not work with AnyConnect on Windows 8.x. • Windows 2008 is not supported; however, we do not prevent the installation of AnyConnect on this OS. Also, Windows Server 2008 R2 requires the optional SysWow64 component • If you are using Network Access Manager on a system that supports standby, Cisco recommends that the default Windows 8.x association timer value (5 seconds) is used.

If you find the Scanlist in Windows appears shorter than expected, increase the association timer so that the driver can complete a network scan and populate the scanlist. Windows Guidelines • Verify that the driver on the client system is supported by Windows 7 or 8. Drivers that are not supported may have intermittent connection problems. Solaris Performance Tools Pdf To Excel. • For Network Access Manager, machine authentication using machine password will not work on Windows 8 or 10 / Server 2012 unless a registry fix described in Microsoft KB 2743127 is applied to the client desktop.

This fix includes adding a DWORD value LsaAllowReturningUnencryptedSecrets to the HKEY_LOCAL_MACHINE System CurrentControlSet Control Lsa registry key and setting this value to 1. This change permits Local Security Authority (LSA) to provide clients like Cisco Network Access Manager with the Machine password. It is related to the increased default security settings in Windows 8 or 10 / Server 2012. Machine authentication using Machine certificate does not require this change and will work the same as it worked with pre-Windows 8 operating systems. Note Machine authentication allows a client desktop to be authenticated to the network before the user logs in. During this time the administrator can perform scheduled administrative tasks for this client machine. Machine authentication is also required for the EAP Chaining feature where a RADIUS server can authenticate both the User and Machine for a particular client.

This will result in identifying company assets and applying appropriate access policies. For example, if this is a personal asset (PC/laptop/tablet), and a corporate credentials are used, the endpoint will fail Machine authentication, but succeed User authentication and the proper network access restrictions are applied to the user's network connection. • On Windows 8, the Export Stats button on the Preferences >VPN >Statistics tab saves the file on the desktop. In other versions of Windows, the user is asked where to save the file.

• AnyConnect VPN is compatible with 3G data cards which interface with Windows 7 or later via a WWAN adapter. Linux Requirements • x86 instruction set. • 64-bit processor. • 20 MB hard disk space. • Dependency on network-manager and libnm library to support NVM. Superuser privileges are required for installation. • libstdc++ users must have libstdc++.so.6(GLIBCXX_3.4) or higher, but below version 4.

• Java 5 (1.5) or later. The only version that works for web installation is Sun Java. You must install Sun Java and configure your browser to use that instead of the default package. • zlib - to support SSL deflate compression • xterm - only required if you're doing initial deployment of AnyConnect via Weblaunch from ASA clientless portal. • libpango 1.0. • iptables 1.2.7a or later. • tun module supplied with kernel 2.4.21 or 2.6.

Mac OS X 10.8 introduces a new feature called Gatekeeper that restricts which applications are allowed to run on the system. You can choose to permit applications downloaded from: • Mac App Store • Mac App Store and identified developers • Anywhere The default setting is Mac App Store and identified developers (signed applications). AnyConnect is a signed application, but it is not signed using an Apple certificate. This means that you must either select the Anywhere setting or use Control-click to bypass the selected setting to install and run AnyConnect from a pre-deploy installation. Users who web deploy or who already have AnyConnect installed are not impacted.

For further information see:. Note Web launch or OS upgrades (for example 10.7 to 10.8) install as expected. Only the pre-deploy installation requires additional configuration as a result of Gatekeeper.

For the latest end-user license agreement, see. For our open source licensing acknowledgments, see. To deploy AnyConnect from an ISE headend and use the ISE Posture module, a Cisco ISE Apex License is required on the ISE Administration node. For detailed ISE license information, see the Cisco ISE Licenses chapter of the. To deploy AnyConnect from an ASA headend and use the VPN and VPN Posture (HostScan) modules, an AnyConnect 4.X Plus or Apex license is required, trial licenses are available, see the. For an overview of the AnyConnect 4.X Plus and Apex licenses and a description of which license the features use, see.

Deploying AnyConnect refers to installing, configuring, and upgrading the AnyConnect client and its related files. The Cisco AnyConnect Secure Mobility Client can be deployed to remote users by the following methods: • Pre-Deploy—New installations and upgrades are done either by the end user, or by using an enterprise software management system (SMS). • Web-Deploy—The AnyConnect package is loaded on the headend, which is either an ASA or ISE server. When the user connects to an ASA or to ISE, AnyConnect is deployed to the client.

• For new installations, the user connects to a headend to download the AnyConnect client. The client is either installed manually, or automatically (web-launch). • Updates are done by AnyConnect running on a system where AnyConnect is already installed, or by directing the user to the ASA clientless portal. • Cloud Update—After the Umbrella Roaming Security module is deployed, you can update any AnyConnect modules using one of the above methods, as well as Cloud Update. With Cloud Update, the software upgrades are obtained automatically from the Umbrella cloud infrastructure, and the update track is dependent upon that and not any action of the administrator. By default, automatic updates from Cloud Update are disabled.

When you deploy AnyConnect, you can include the optional modules that enable extra features, and client profiles that configure the VPN and other features. Keep in mind the following: • All AnyConnect modules and profiles can be pre-deployed. When pre-deploying, you must pay special attention to the module installation sequence and other details.

• The Customer Experience Feedback module and the Hostscan package, used by the VPN Posture module, cannot be web-deployed from the ISE. • The Compliance Module, used by the ISE Posture module, cannot be web-deployed from the ASA. For more information about deploying the AnyConnect modules, see the. Note Make sure to update the localization MST files with the latest release from CCO whenever you upgrade to a new AnyConnect package.

When you upgrade from any 2.5.x version of AnyConnect, the AnyConnect Secure Mobility Client performs the following: • Upgrades all previous versions of the core client and retains all VPN configurations. • Upgrades any Host Scan files used by AnyConnect. • If you install Network Access Manager, AnyConnect retains all CSSC 5.x configuration for use with Network Access Manager, then removes CSSC 5.x.

• Does not upgrade or remove the Cisco IPsec VPN client. However, the AnyConnect client can coexist on the computer with the IPsec VPN client. • Does not upgrade and cannot coexist with Cisco’s ScanSafe AnyWhere+. You must uninstall AnyWhere+ before installing the AnyConnect Secure Mobility Client.

Note If you are upgrading from the legacy Cisco VPN client, the MTU value on the physical adapters may have been lowered to 1300. You should restore the MTU back to the default (typically 1500) for each adapter to achieve optimal performance when using AnyConnect. Upgrading from AnyConnect 2.2 is not supported using the ASA or Weblaunch. You must uninstall AnyConnect 2.2 then install the new verion either manually or using an SMS. This issue applies to Internet Explorer versions 10 and 11, on Windows versions 7 and 8.

When the Windows registry entry HKEY_CURRENT_USER Software Microsoft Internet Explorer Main TabProcGrowth is set to 0, Active X has problems during AnyConnect web deployment. See for more information. The solution to is to: • Run a 32-bit version of Internet Explorer. • Edit the registry entry to a non-zero value, or remove that value from the registry. Note On Windows 8, starting Internet Explorer from the Windows start screen runs the 64-bit version. Starting from the desktop runs the 32-bit version.

Cisco only provides fixes and enhancements based on the most recent 4.x release. TAC support is available to any customer with an active AnyConnect 4.x term/contract running a released version of AnyConnect 4.x. If you experience a problem with an out-of-date software version, you may be asked to validate whether the current maintenance release resolves your issue. Software Center access is limited to AnyConnect 4.x versions with current fixes. We recommend that you download all images for your deployment, as we cannot guarantee that the version you are looking to deploy will still be available for download at a future date.

The recommended version of AnyConnect for macOS 10.13 (High Sierra) is AnyConnect 4.5.02XXX and above. AnyConnect 4.5.02XXX and above has additional functionality and warnings to guide users through the steps needed to leverage AnyConnect’s complete capabilities, by enabling the AnyConnect software extension in their macOS Preferences ->Security & Privacy pane.

The requirement to manually enable the software extension is a new operating system requirement in macOS 10.13 (High Sierra). Additionally, if AnyConnect is upgraded to 4.5.02XXX and above before a user’s system is upgraded to macOS 10.13 or later, the user will automatically have the AnyConnect software extension enabled. Users running macOS 10.13 (High Sierra) with a version of AnyConnect earlier than 4.5.02XXX must enable the AnyConnect software extension in their macOS Preferences ->Security & Privacy pane. Although AnyConnect 4.4.04030 and 4.5.01044 have been tested to work with macOS 10.13 (High Sierra), those users will not have the additional functionality and warning guidance added to AnyConnect 4.5.02XXX.

You may need to manually reboot after enabling the extension prior to AnyConnect 4.5.02xxx. As described in, macOS system administrators potentially have additional capabilities to disable User Approved Kernel Extension Loading, which would be effective with any currently supported version of AnyConnect.

When upgrading to Windows 10 Creator Update (April 2017), you may encounter a Windows Defender message that the AnyConnect adapter has an issue. Windows Defender instructs you to enable the adapter under the Device Performance and Health section. In actuality, the adapter should be disabled when not in use, and no manual action should be taken. This false positive error has been reported to Microsoft under Sysdev # 11295710. AnyConnect 4.4MR1 (or later) and 4.3MR5 are compatible with Windows 10 Creators Edition (RS2).

AnyConnect 4.1MR4(4.1.04011) and later are compatible with Windows 10 official release. Technical Assistance Center (TAC) support is available beginning on 7/29/2015. For best results, we recommend a clean install of AnyConnect on a Windows 10 system and not an upgrade from Windows 7/8/8.1.

If you are planning to perform an upgrade from Windows 7/8/8.1 with AnyConnect pre-installed, make sure that you first upgrade AnyConnect prior to uprading the operating system. The Network Access Manager Module must be uninstalled prior to upgrading to Windows 10. After the system upgrade is complete, you can re-install Network Access Manager on the system. You may also choose to fully uninstall AnyConnect and re-install one of the supported versions after upgrading to Windows 10. Formerly, if a split-include network was a Supernet of a Local Subnet, the local subnet traffic was not tunneled unless a split-include network that exactly matches the Local Subnet was configured. With the resolution of CSCum90946, when a split-include network is a Supernet of a Local Subnet, the Local Subnet traffic is tunneled, unless a split-include (deny 0.0.0.0/32 or::/128) is also configured in the access-list (ACE/ACL). The new behavior requires the following configurations when a Supernet is configured in the split-include and the desired behavior is to allow LocalLan access: • access-list (ACE/ACL) must include both a permit action for the Supernet and a deny action for 0.0.0.0/32 or::/128.

• Enable Local LAN Access in the AnyConnect profile (in the Preferences Part 1 menu of the profile editor. (You also have the option to make it user controllable.). A secure gateway with a SHA-1 certificate or a certificate with SHA-1 intermediate certificates may no longer be considered valid by a Windows Internet Explorer 11 / Edge browser or a Windows AnyConnect endpoint after February 14, 2017. After February 14, 2017, Windows endpoints may no longer consider a secure gateway with a SHA-1 certificate or intermediate certificate as trusted. We highly recommend that your secure gateway does not have a SHA-1 identity certificate and that any intermediate certificates are not SHA-1. Microsoft has made modifications to their original plan of record and timing. They have published details for how to.

Cisco is not able to make any guarantees of correct AnyConnect operation for customers with SHA-1 secure gateway or intermediate certificates or running old versions of AnyConnect. Cisco highly recommends that customers stay up to date with the current maintenance release of AnyConnect in order to ensure that they have all available fixes in place. The most up-to-date version of AnyConnect 4.x and beyond are available for customers with active AnyConnect Plus, Apex, and VPN Only terms/contracts. And should no longer be used for any deployments. Note Cisco has validated that AnyConnect 4.3 and 4.4 (and beyond) releases will continue to operate correctly as Microsoft further phases out SHA-1.

Long term, Microsoft intends to distrust SHA-1 throughout Windws in all contexts, but their current advisory does not provide any specifics or timing on this. Depending on the exact date of that deprecation, many earlier versions of AnyConnect may no longer operate at any time. Refer to for further information. The Firefox certificate store on Mac OS X is stored with permissions that allow any user to alter the contents of the store, which allows unauthorized users or processes to add an illegitimate CA into the trusted root store. Anyconnect no longer utilizes the Firefox store for either server validation or client certificates. If necessary, instruct your users how to export your AnyConnect certificates from their Firefox certificate stores, and how to import them into the Mac OS X keychain.

The following steps are an example of what you may want to tell your AnyConnect users. • Navigate to Firefox >Preferences >Advanced, Certificates tab, click View Certificates.

• Select the Certificate used for AnyConnect, and click Export. Your AnyConnect Certificate(s) will most likely be located under the Authorities category. Verify with your Certificate Administrator, as they may be located under a different category (Your Certificates or Servers).

• Select a location to save the Certificate(s), for example, a folder on your desktop. • In the Format pull down menu, select X.509 Certificate (DER). Add the.der extension to the certificate name, if required. Note If more than one AnyConnect Certificate and/or a Private Key is used/required, repeat the above process for each Certificate). • Launch KeyChain. Navigate to File, Import Items, and select the Certificate that you exported from Firefox. In the Destination Keychain:, select the desired Keychain.

The login Keychain that is used for this example may not be the one used at your company. Ask your Certificate Administrator to which Keychain your certificate(s) should be imported. • In the Destination Keychain:, select the desired Keychain. The login Keychain that is used for this example may not be the one used at your company. Ask your Certificate Administrator to which keychain your certificate(s) should be imported. On many newer Linux distributions, the AnyConnect UI may fail to start with the error: error while loading shared libraries: libpangox-1.0.so.0: cannot open shared object file: No such file or directory The missing library is obsolete and is no longer available. This impacts other applications, not just AnyConnect.

Pango has released the source code of a compatible library that has been built by others and is available online. To resolve this problem, find and install either the package pangox-compat-0.0.2-2.el7.x86_64.rpm or pangox-compat-0.0.2-3.fc20.x86_64.rpm. We have seen instances where Apple's Broadband Tuner application (from 2005) was used with Mac OS X 10.9, That application changes the network settings in sysctl.conf, which can cause connection problems. That application was designed for much older versions of the Mac OS.

We suspect that the current default OS settings take broadband networks into consideration, so most users will not need to take any action. Running AnyConnect 3.1.04074 along with the modified sysctl settings may generate the following message: The VPN client driver encountered an error.please restart. When the Network Access Manager operates, it takes exclusive control over the network adapters and blocks attempts by other software connection managers (including the Windows native connection manager) to establish connections. Therefore, if you want AnyConnect users to use other connection managers on their endpoint computers (such as iPassConnect Mobility Manager), they must disable Network Access Manager either through the Disable Client option in the Network Access Manager GUI, or by stopping the Network Access Manager service. The AnyConnect client relies on the Windows Cryptographic Service Provider (CSP) of the certificate for hashing and signing of data required during the IKEv2 authentication phase of the IPsec/IKEv2 VPN connection. If the CSP does not support SHA 2 algorithms, and the ASA is configured for the pseudo-random function (PRF) SHA256, SHA384, or SHA512, and the connection profile (tunnel-group) is configured for certificate or certificate and AAA authentication, certificate authentication fails.

The user receives the message Certificate Validation Failure. This failure occurs for Windows only, for certificates that belong to CSPs that do not support SHA 2-type algorithms. Other supported OSs do not experience this problem.

To avoid this problem you can configure the PRF in the IKEv2 policy on the ASA to md5 or sha (SHA 1). Alternatively, you can modify the certificate CSP value to native CSPs that work such as Microsoft Enhanced RSA and AES Cryptographic Provider. Do not apply this workaround to SmartCards certificates. You cannot change the CSP names. Instead, contact the SmartCard provider for an updated CSP that supports SHA 2 algorithms. Caution Performing the following workaround actions could corrupt the user certificate if you perform them incorrectly. Use extra caution when specifying changes to the certificate.

You can use the Microsoft Certutil.exe utility to modify the certificate CSP values. Certutil is a command-line utility for managing a Windows CA, and is available in the Microsoft Windows Server 2003 Administration Tools Pack.

You can download the Tools Pack at this URL: Follow this procedure to run Certutil.exe and change the Certificate CSP values: • Open a command window on the endpoint computer. • View the certificates in the user store along with their current CSP value using the following command: certutil -store -user My. AnyConnect sometimes receives and drops packet fragments with some routers, resulting in a failure of some web traffic to pass. To avoid this, lower the value of the MTU. We recommend 1200.

The following example shows how to do this using CLI: hostname# config t hostname(config)# group-policy DfltGrpPolicy attributes hostname(config-group-policy)# webvpn hostname(config-group-webvpn)# anyconnect mtu 1200 To set the MTU using ASDM, go to Configuration >Network (Client) Access >Group Policies >Add or Edit >Advanced >SSL VPN Client. Windows Active Directory Wireless Group Policies manage the wireless settings and any wireless networks that are deployed to PCs in a specific Active Directory Domain. When installing the Network Access Manager, administrators must be aware that certain wireless Group Policy Objects (GPOs) can affect the behavior of the Network Access Manager. Administrators should test the GPO policy settings with the Network Access Manager before doing full GPO deployment. The following GPO conditions may prevent the Network Access Manager from operating as expected: • When using the Windows 7 or later, Only use Group Policy profiles for allowed networks option. Unless an exception for an IPv6 address, domain name, address range, or wild card is specified, IPv6 web traffic is sent to the scanning proxy where it performs a DNS lookup to see if there is an IPv4 address for the URL the user is trying to reach. If the scanning proxy finds an IPv4 address, it uses that for the connection.

If it does not find an IPv4 address, the connection is dropped. If you want all IPv6 traffic to bypass the scanning proxies, you can add this static exception for all IPv6 traffic: /0. Doing this makes all IPv6 traffic bypass all scanning proxies.

This means that IPv6 traffic is not protected by Cisco Cloud Web Security. After one uses AnyConnect to establish a VPN session with Windows 7 or later on a remote LAN, the network browsers on the other devices in the user’s LAN display the names of hosts on the protected remote network. However, the other devices cannot access these hosts. To ensure the AnyConnect host prevents the hostname leak between subnets, including the name of the AnyConnect endpoint host, configure that endpoint to never become the master or backup browser.

• Enter regedit in the Search Programs and Files text box. • Navigate to HKEY_LOCAL_MACHINE System CurrentControlSet Services Browser Parameters • Double-click MaintainServerList. The Edit String window opens. • Close the Registry Editor window. An AnyConnect certificate revocation warning popup window opens after authentication if AnyConnect attempts to verify a server certificate that specifies the distribution point of an LDAP certificate revocation list (CRL) if the distribution point is only internally accessible.

If you want to avoid the display of this popup window, do one of the following: • Obtain a certificate without any private CRL requirements. • Disable server certificate revocation checking in Internet Explorer. Caution Disabling server certificate revocation checking in Internet Explorer can have severe security ramifications for other uses of the OS. When the AnyConnect client for Mac OS X attempts to create an SSL connection to a gateway running IOS, or when the AnyConnect client attempts to create an IPsec connection to an ASA from behind certain types of routers (such as the Cisco Virtual Office (CVO) router), some web traffic may pass through the connection while other traffic drops. AnyConnect may calculate the MTU incorrectly. To work around this problem, manually set the MTU for the AnyConnect adaptor to a lower value using the following command from the Mac OS X command line: sudo ifconfig utun0 mtu 1200 (For Mac OS X v10.7 and later).

If users WebLaunch from the ASA headend to start AnyConnect on a Mac, and the Java installer fails, a dialog box presents a Manual Install link. Users should do the following when this happens: • Click Manual Install. A dialog box presents the option to save a.dmg file that contains an OS X installer.

• Mount the disk image (.dmg) file by opening it and browsing to the mounted volume using Finder. • Open a Terminal window and use the CD command to navigate to the directory containing the file saved. Open the.dmg file and run the installer. • Following the installation, choose Applications >Cisco >Cisco AnyConnect Secure Mobility Client to initiate an AnyConnect session, or use Launchpad. The AnyConnect Secure Mobility Client includes an Application Programming Interface (API) for those who want to write their own client programs. The API package contains documentation, source files, and library files to support a C++ interface for the Cisco AnyConnect VPN Client. You can use the libraries and example programs for building on Windows, Linux and MAC platforms.

The Makefiles (or project files) for the Windows platform are also included. For other platforms, it includes platform specific scripts showing how to compile the example code. Network administrators can link their application (GUI, CLI, or embedded application) with these files and libraries.

You can download the APIs from Cisco.com. For support issues regarding the AnyConnect API, send e-mail to the following address: anyconnect-api-support@cisco.com.
