Getting help

If you have problems building or using OpenConnect, or other questions or comments, please send email to the mailing list described below. You don't need to be subscribed to the list; you only need to click on the email address below, and send a plain text (not HTML) mail.

A lot of people seem to post questions about OpenConnect on random web forums, where they are unlikely to get a quick or knowledgeable response. It's almost as if they don't want a coherent response, which is strange. Please, don't do that.

Mailing list

There is a mailing list at The list does not accept HTML email, so please make sure you post as plain text only.

As mentioned above, you do not have to be subscribed to the list in order to post a question.

It's usually best to read the recent messages in the archive before posting a question that is likely to have been asked before.

If you do want to subscribe to the mailing list, you can do so from the Mailman admin page.

If you are posting debugging output from openconnect to the mailing list, do not include a line which looks like this:
Set-Cookie: webvpn=835278264@921600@1221512527@6B9EC24DEB2F59E242F75B424D42F223D0912984;PATH=/
That HTTP cookie is all that's needed to grant access to the VPN session you just logged in to — it's almost as bad as giving your password away. Version 2.26 or later of OpenConnect will automatically filter this out of the debugging output for you.
