ssh connection refused
 
Hi,

I am getting connection refused when I try to ssh to
RedHat 9.0 Linux installation on IBM xServer 335. Both
machines are inside the firewall.

I did a medium security installation and expected ssh
to work by default. I checked sshd is running. On the IBM
machine I can ssh to itself successfully. From IBM, I can
also browse the web, so I can see outside network. I tried
adding ssd: ALL to /etc/hosts.allow but it didn't make
any difference. From my machine, I can ping the IBM xServer.

Any suggestions would be greatly appreciated.

there will be an ssh log file in there somewhere... maybe you're trying to do it as root or something? find the log file and it should be pretty obvious. you've given us very little info to go on though....

on the remote host trying to connect it says:

Sounds Like IPTABLES
 
Sounds like iptables (or ipchains) isn't allowing connections on port 22. A quick and dirty way to check in to type "/sbin/service iptables stop" as root then try to connect by SSH. This should flush all the chains and reset to the default accept policy. "iptables -L" will list all the active chains.

Here is a HOWTO for ipchains which pretty well applies to iptables too.

thank you !
 
disabling the firewall fixed the problem as you pointed out. Thanks!
