ssh: Connection refused when access remotely
I recently installed ssh server openssh-server in my fedora 16. I added my friend user account to my sshuser list. When my friend tried to connect my server computer via ssh using following command
then it shows following error
ssh: connect to host 192.168.1.123 port 22: Connection refused
but when i tried locally from my machine the server was connected.
root@localhost /]# ssh [email protected]
[email protected]'s password:
Last login: Tue Feb 26 13:24:42 2013 from localhost.localdomain
[sudip@localhost ~]$
Also, my firewall is allowing SSH and SHH is running on port 22. So how can i troubleshoot the error??
thank you in advance.
EDIT: I already started sshd using service sshd restart
EDIT2: output of: iptables -n -L -v

The workstation also uses fedora 16
You can use ssh -vvv [email protected] to get debug info on the connection. If -vvv is too much info you can use -vv or -v for less detailed debug info.
On the remote server, you should be able to see some info in /var/log/message or /var/log/syslog also.
A combo of those 2 things should point you in the right direction.
The Connection Refused message generally means that nothing is listening on that ipaddress:port. Check to see that sshd is listening on your 192.168.1.123:22
netstat -tnlp | grep :22
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 6809/sshd
tcp 0 0 :::22 :::* LISTEN 6809/sshd
The above output is indicating that sshd is listening on all available ipv4 and ipv6 interfaces. If yours is different then you should check the ListenAddress directives in your sshd_config file.
Executing ssh -vv [email protected] will show you the detailed info of the SSH connetion. Also you can try "telnet 192.168.1.123 22" (telnet hostname port) in order to verify whether port 22 is listening.
