    I suppose the reinstallation was on local machine, not remote machine, correct?

    Try and error:
    1. your wireless router doesn't forward ping and SSH to your local machine (other ip-address of your local machine?)
    2. maybe your internet service provider gave you a new IP address (dhcp?) (due to your reinstallation, your router was also unplugged?).
    3. try to check the traces (errors) on your wireless router (most routers can trace incoming messages).
    4. if you're sure that router forward external requests, you should see the errors in /var/log/messages ('$> tail -f /var/log/messages')


    To be sure the firewall is disabled: '$> service iptables stop' (but don't forget to re-enable it again '$> service iptables start' !!!)

    Henry,

    It sounds like either the port-forwarding on your router is not properly configured, or you are not using the right IP address from the remote client to get to it, or when connecting via SSH, you or not using the redirected port number (if any) that is defined in your router config. To get your internet ip address, try this site to get the IP address assigned to you by your ISP.

    E.g., from the remote client, you should be doing something like:

    ssh -p 2222 xxx.xxx.xxx.xxx

    where 2222 is the redirected port that your router uses to forward external SSH requests internally to port 22 on your private SSH server and xxx.xxx.xxx.xxx is the internet IP address that your ISP assigns to you.

    Also, I don't know if anyone else has mentioned it, but you should also check out /var/log/secure for failed SSH login attempts.

    Solved. The bug was the router had the wrong rule.
    Thanks all for the assistance.
