OpenConnect

From OpenConnect:

OpenConnect is a client for Cisco's AnyConnect SSL VPN, which is supported by the ASA5500 Series, by IOS 12.4(9)T or later on Cisco SR500, 870, 880, 1800, 2800, 3800, 7200 Series and Cisco 7301 Routers, and probably others.

Installation

Install the openconnect package from the Official repositories.

Usage

OpenConnect can be used with NetworkManager, or manually via the command line.

NetworkManager

Install the networkmanager-openconnect package from the official repositories. Then configure and connect with nm-applet (network manager's tray icon) or similar utility. After installation, restart the NetworkManager.service.

See NetworkManager for details.

Command Line

Download a more up-to-date script that OpenConnect will use to setup routing and DNS information (the only difference, currently, between this script and the one that comes with vpnc is using /usr/sbin/resolvconf instead of /sbin/resolvconf, there should be an AUR package for this eventually):

# wget http://git.infradead.org/users/dwmw2/vpnc-scripts.git/blob_plain/HEAD:/vpnc-script

Replace references to /sbin/resolvconf with /usr/bin/resolvconf:

# sed -i 's/\/sbin\/resolvconf/\/usr\/bin\/resolvconf/g' vpnc-script

Make it executable:

# chmod +x vpnc-script

Now run OpenConnect as root with the script downloaded above, and provide the gateway:

# openconnect --script ./vpnc-script mygateway.com
Warning: The script has not been adapted to Arch Linux. You will probably need to set your /etc/resolv.conf manually with the proper information. After you run the openconnect command.

More advanced invocation with username and password:

# echo -n 'passwd' | openconnect -u user mygateway.com

Usage with screen

Run openconnect in a screen session, for example your script might contain:

$ screen -dmS my-vpn sh
$ screen -S my-vpn -X stuff "sudo openconnect --script ~/bin/vpnc-script vpn.foo.bar
$ "
$ screen -r my-vpn

Re-connect to the screen session:

$ screen -r my-vpn

Use ctrl-c to close and tear down the vpn connection.
