Stalled SSH connections
·95 words·1 min
I spent some time adjusting my SSH configuration because I often get stalled connections to my servers but I never got that fixed until recently, when I started looking in my firewall settings on the pfSense.
After changing the Firewall Optimization Settings within System → Advanced → Firewall & NAT to Conservative I had no more of these hangs of my SSH sessions.
I use the ControlMaster
setting in my SSH configuration so the stalled
connections have to be killed with something like
$ ssh -O exit {short hostname}
every time – which is annoying.
