Openconnect (anyconnect) on Ubuntu Jammy

Sorry, I ought to have posted this weeks in the past to save lots of others a while.

In case you are working openconnect-sso to connect with a Cisco anyconnect VPN, then once you improve to Ubuntu Jammy, openssl 3.0 could cease openconnect from working. The best solution to work round that is to make use of a customized configuration file as follows:


cat > $HOME/ssl.cnf
openssl_conf = openssl_init

[openssl_init]
ssl_conf = ssl_sect

[ssl_sect]
system_default = system_default_sect

[system_default_sect]
Choices = UnsafeLegacyRenegotiation
EOF

Then use this configuration file (solely) when working openconnect:


OPENSSL_CONF=~/ssl.cnf openconnect-sso --server=your-server.no matter.com
