hi

I have CentOS distribition and I am within a local network 192.168.X.X.
I have access to any PC in my network using ssh from my PC but I can not do this from another PC to connect to my PC.I can neither ping nor ssh my PC. I disabled the firewall and I checked the iptables and I think that everything is right. the port 22 is open but I have the following error message:
ssh: connect to host 192.168.x.x port 22: No route to host

is there any one who can help me?

That error, "No Route to Host", is indicative of not having a default gateway set. You will want to make sure that there is a default gateway by typing [B]route[B] to show the routes available. If you have an entry with the flag "UG" then you have a Default Gateway and something else may be the problem.

To set the default gateway, try route add default 192.168.1.1, where 192.168.1.1 is the default gateway of your network.

I found that there is a default entry in my network and the problem that even within the local network, I cannot get access to my PC

Is it possible that the two machines are on different subnets? Is it possible for you to post all route and ifconfig results for computer1 and computer2?

are you sure sshd is running ?

Code:

it-etch:~# netstat -lnp | grep sshd
tcp6       0      0 :::22                   :::*                    LISTEN     3432/sshd

can you ssh from your local machine to itself ?

ssh localhost
