Hi, I have a Raspberry Pi as wireless router and Tor proxy. Everything from wlan0 is directed to Tor. When I am taking SSH connection using this wireless transparent proxy with my laptop the SSH connection is sometimes left alive forever after the laptop is closed.
How it works: 1) I am taking SSH connection from my laptop to an SSH server. 2) I am walking away from my home with the laptop and the connection to the wireless network is lost. 3) The SSH connection stays on (from the server point of view) forever. The wireless router is keeping the SSH connection alive until I reboot it. I don't understand how this is possible. In the wireless router I am running the Tor software version 0.2.3.25. Moreover, there is nothing special in the SSH server. It seems that the connection stays on until the router is rebooted. I see the SSH connection coming from some exit node: [juha@server ~]$ who juha pts/1 2014-07-07 13:04 (:pts/2:S.0) juha pts/0 2014-07-07 10:43 (h-213.61.149.100.host.de.colt.net) [juha@server ~]$ sudo netstat -tnpa | grep ESTABLISHED.*sshd tcp 0 0 XXX.XXX.XXX.XXX:22 213.61.149.100:19120 ESTABLISHED 8743/sshd The SSH server has the default settings (keep alive settings are commented out): [juha@server ~]$ sudo grep -ni alive /etc/ssh/sshd_config 114:#TCPKeepAlive yes 119:#ClientAliveInterval 0 120:#ClientAliveCountMax 3 So, how does the SSH connection is kept alive forever without the client side?
