I need to connect to the office VPN from a linux machine. I'm able to connect to it only via Citrix NetScaler Gateway on Windows. The connection needs the secondary password (in my case is an OTP from Mobile Pass App) and I have all the client and ca certificates needed.
I've tried Cisco AnyConnect but I always get the following error message:
AnyConnect cannot confirm it is connected to your secure gateway. The local network may not be trustworthy. Please try another network.
I've also tried OpenConnect with which I always got:
XML response has no "auth" node
Other VPN clients like FortiClient does not support secondary password so I can't make them work and I can't find any solution for those errors. Is there a way to make one of them working or obtain a version of Citrix NetScaler Gateway compatible with Ubuntu?
