  1. Older versions of MobaXterm can cause problems with ssh key authentication. If you want to set up ssh keys with MobaXterm, such as outlined in our step-by-step guide, please make sure you’re using a up to date version of the software.
  2. Connections to act-ssh or mft are timed out when you are connected to the VPN. If you want to use act-ssh, please make sure that the VPN is disconnected.
  3. If you are connecting from a mac via terminal and can’t see any graphics display despite using the -X/-Y flag in your ssh command, check that you have a recent version of the XCode tools installed, which enables X11 graphics forwarding on macs.
