Hello, I've been using the openconnect package on a Ubuntu 15.10 x64 installation for several months now and am finding that it continually drops the connection. This happens at least once withing every 20 minutes and makes it nearly impossible to do my work remotely. Lately I have had to resort to using a Windows box with the 'real' Cisco client software as it seems to work without issue. I've googled around to see others have the same problem, but no resolution. Is there a way to disable DPD? Here's an excerpt from my syslog. Any help would be appreciated....
