SSH disconnected after only several commands
Hi. Thanks for your work btw.
After yesterday update, i encountered strange ssh problem. I got disconnected with Timeout. server not responding after issuing several shell command. If i left my ssh connection idle, or tail -f something, it wont disconnects.
Is that ssh problem or sstp-client? I tried ssh-ing to several boxes with same result.
