Cisco Vpn Linux

by



OpenConnect is a cross-platform multi-protocol SSL VPN client which supports a number of VPN protocols:

  • DESCRIPTION The program openconnect connects to Cisco 'AnyConnect' VPN servers, which use standard TLS and DTLS protocols for data transport. The connection happens in two phases. First there is a simple HTTPS connection over which the user authenticates somehow - by using a certificate, or password or SecurID, etc.
  • Sudo apt-get install network-manager-vpnc. That will install vpnc, network-manager-vpnc and network-manager-vpnc-gnome. Now LEFT click on your network manager applet: And choose 'Configure VPN.' , then click 'Add' and drop the menu to 'Cisco Compatible VPN'. And enter your details.

For 64-bit clients: '˜tar xvfz anyconnect-linux64x.0217-k9.tar.gz' Open the newly-extracted folder to find the VPN folder. Right-click the 'vpninstall.sh' file. Double-click Run. Use the GUI to install the Cisco AnyConnect Secure Mobility Client at the root level. For some versions of Linux, such as Ubuntu, using the CLI will be necessary.

  • Cisco AnyConnect (--protocol=anyconnect)
  • Juniper SSL VPN (--protocol=nc)
  • Pulse Connect Secure (--protocol=pulse
  • Palo Alto Networks GlobalProtect SSL VPN (--protocol=gp)
  • F5 Big-IP SSL VPN (--protocol=f5)
  • Fortinet Fortigate SSL VPN (--protocol=fortinet)

OpenConnect is not officially supported by, or associated in any waywith Cisco Systems, Juniper Networks, Pulse Secure, Palo Alto Networks, F5,or Fortinet, or any of the companies whose protocols we may support in the future.It just happens to interoperate with their equipment. Trademarks belong totheir owners in a rather tautological and obvious fashion.

An openconnect VPN server (ocserv), which implementsan improved version of the Cisco AnyConnect protocol, has also beenwritten.

Linux

OpenConnect is released under the GNU Lesser Public License, version 2.1.

Motivation

Development of OpenConnect was started after a trial of the Cisco AnyConnectclient under Linux found it to have many deficiencies:

  • Inability to use SSL certificates from a TPM or PKCS#11 smartcard, or even use a passphrase.
  • Lack of support for Linux platforms other than i386.
  • Lack of integration with NetworkManager on the Linux desktop.
  • Lack of proper (RPM/DEB) packaging for Linux distributions.
  • 'Stealth' use of libraries with dlopen(), even using the development-only symlinks such as libz.so — making it hard to properly discover the dependencies which proper packaging would have expressed
  • Tempfile races allowing unprivileged users to trick it into overwriting arbitrary files, as root.
  • Unable to run as an unprivileged user, which would have reduced the severity of the above bug.
  • Inability to audit the source code for further such 'Security 101' bugs.

Naturally, OpenConnect addresses all of the above issues, and more.

New protocols

Adding new protocols to OpenConnect is relatively simple, andadditional protocols have been added over the years since usingOpenConnect allows a developer to concentrate on the protocol itselfand most of the boring details about platform-specific tunnel managementand IP configuration, and handling of client SSL certificates, are alreadyresolved.

If you have a protocol which you think it makes sense to support inOpenConnect, especially if you are able to help with interoperabilitytesting, please file an issuein GitLab.

Consistent multi-protocol support

Wherever possible, OpenConnect presents a uniform API and command-lineinterface to each of these VPNs. For example,openconnect --force-dpd=10will attempt dead peer detection every 10 seconds on every VPN thatsupports it, even though the actual mechanism used may be protocol-specific.Protocol-specific features and deficiencies are described on theindividual protocol pages.

Note: If you are using a University of Michigan MiWorkspace managed device, VPN software and profiles are configured for you. Please see MiWorkspace Work Remotely for more information. If you need help connecting to the VPN on a managed device, please contact the ITS Service Center. These pages provide VPN configurations for unmanaged devices (e.g., research users, BYOD users).
Note: Sponsored affiliates are able to use the VPN if they are issued a University of Michigan ID (UMID) number with their sponsorship credentials.

The instructions below are for Ubuntu Linux distribution. Instructions should be similar for other distributions.

Additional information can be found in the Cisco Release Notes for AnyConnect Client.

Note: In order for AnyConnect to trust the VPN server certificates and work properly, you must have Firefox installed on your system and run at least once.

Download and Extract the Cisco AnyConnect VPN Client

  1. Download the appropriate VPN client for your university role:
    • Faculty, Staff, Students, or Sponsored Affiliates: Cisco AnyConnect VPN client for Linux.
    • Alumni and Retirees: Cisco AnyConnect VPN client for Linux.
  2. When prompted, authenticate using your uniqname and UMICH password.
  3. Extract the VPN files:
    1. In a terminal, enter $ cd~/Downloads.
    2. For faculty, staff, students, and sponsored affiliates:

Enter $ tar zxvf UMVPN-linux.tar.gz to extract the files.

  1. For alumni and retirees:

Cisco Vpn Download

Enter $ tar zxvf UMVPN-Alumni-Retiree-linux.tar.gz to extract the files.

  1. Change into the AnyConnect VPN Directory and run the installer.
    • Enter $ cd anyconnect-linux/vpn.
  2. Next, enter $ sudo ./vpn_install.sh.
  3. You are notified that you have accepted the license agreement while the Cisco AnyConnect Secure Mobility Client is installed.

Start the VPN Client

Important You must have a network connection to connect via the VPN.

  1. Launch the Cisco AnyConnect Secure Mobility client.
  2. Select UMVPN - All Traffic or UMVPN - Only U-M Traffic from the profile drop-down list.
  3. Click Connect.
  4. When prompted, authenticate using your uniqname and UMICH password.
  5. Complete Duo Two-Factor authentication.

Troubleshooting

  1. If the following failure message appears: Failed to start vpnagentd.service: Unit vpnagentd.service failed to load: No such file or directory you may need to add a package:
    • lib32z1
    • The latest package of lib32ncurses
  2. If you are still having problems you may need an additional package:
    • network-manager-openconnect

  3. Finally, you may need to restart the machine before re-running the VPN installer.

Note: Currently, both Duo Two-Factor authentication VPN profiles and VPN profiles that do not require Duo Two-Factor are available. Choose the Legacy option for the appropriate VPN profile if Duo Two-Factor is not needed.
