To whom it may concern,
I have used openconnect to log into my University's VPN from my
Linux computer for a few years without a problem. Approximately at the
start of this year, the IT department made some sort of change (I think
they updated the Cisco VPN server, but m not sure) and I have not been
able to connect to the VPN. When I try to use openconnect, I get the
following error string:
root@My-Computer:~# openconnect --protocol=anyconnect {VPN-DNS}

Please upgrade your AnyConnect Client
Failed to complete authentication
I have the anyconnect client on a Windows computer and have been able to
successfully connect to {VPN-DNS} using that, but I need to be able to
use it on my Linux computer. My IT folks aren't very helpful, simply
telling me that I need to use either the Linux version of anyconnect or
use my Windows computer. Unfortunately, I run Slackware Linux and Cicso
only supports Ubuntu. Amy suggestions on how to get openconnect working
again are greatly appreciated.
Sincerely,
Dan
