failed all server access from other machine
 

Hi all,

Yesterday, in my company, someone pressed the shutdown button of the Linux server by accident.
Then after that we relialized that our local email couldn't access any more. (I'm not sure because of that improper shutdown or not)
The mail server is running on that Linux server.
Then I tried to log on the "telnet" and "ssh" onto the sever but it failed. The error message of the telnet is

"Connecting to 10.0.0.60...Could not open a connection to host on port 23 : Connect failed"

But I'm sure that all the telnet and ssh, etc servers are running.

Then I tried to access the webpage of the local web-server running on that machine and it also failed.
That means I cannot access anything to that server.
But I can ping it.
Is it firewall problem? How do I check it?
Any idea?

The Server is Suse Linux 7.0 , the kernel is 2.2.6

Ok, now I checked the ipchains.

ipchains -L

and it shows

Chain input (policy ACCEPT):
Chain forward (policy ACCEPT):
Chain output (policy ACCEPT):

The outputs are only this.
What does it mean? Does it mean that all input, output connections are accepted? Or it's not specified yet so it refused all connections?

Have you tried to check net configuration on your server?

Try ifconfig and route
