Hi, I am trying to set up an ssh server on my home computer so that I can access it from work. I forwarded port 22 from my router (apple airport extreme) and got my rsa keys ready and thought I was going to be good to go until I checked my server ($ ssh localhost) and got the message:I tried to open the ports on my firewall (using firestarter) and I looked this up but no one's solutions seemed to work for me.Quote:
ssh: connect to host localhost port 22: Connection refused
Please help!
There are 4 possible things causing this.
1) Port forwarding in your router is incorrect.
2) Firewall issues.
3) ssh server is not running.
4) ssh is set to a different port.
When trying it locally it would be one of the last 3.
"ps aux | grep ssh" returns:"cat /etc/services | grep 22" returns:Quote:
root 916 0.0 0.0 5548 912 ? Ss 18:17 0:00 /usr/sbin/sshd
tommy 2190 0.0 0.0 3280 360 ? Ss 18:18 0:00 /usr/bin/ssh-agent /usr/bin/dbus-launch --exit-with-session gnome-session
tommy 2853 0.0 0.0 3324 888 pts/0 S+ 19:04 0:00 grep --color=auto ssh
Does that help a diagnosis?Quote:
ssh 22/tcp # SSH Remote Login Protocol
ssh 22/udp
Have you tried:
ssh 127.0.0.1
ssh <Your IP>
If you are behind a firewall you can try uninstalling it to check if that is the problem (then reinstall it if you like).
It might help if you could post /etc/ssh/ssh_config and /etc/ssh/sshd_config. Does machine have static or DHCP address. There's another thread around (somewhere) that mentions SSH being picky about permissions of some directories...
The ip address is static. On an interesting note, /etc/init.d/sshd does not exist.

The server is listening on port 7777, but the client is using port 22?
That solved it! I changed that and the ServerBitsKey to 1024 and it worked fine.
please post steps ..
