Hi !!

I am trying to connect to a red hat 8 server that is on a DMZ .
I recieve a connection refused error.
whan I am sitting on that server and I telnet to local host on port 22 the server answeres. I am passing throw one Firewall but on the FW logs I see that all the connections in ssh to that server are accepted.

what to do ?

thanks

You might need to open up the server to outside ssh requests (telneting to localhost uses the loopback interface). So make sure the server allows port 22 connections on the ext. interface. Check /etc/sysconfig/iptables and make sure you have something that resembles this:

-A INPUT -p tcp --dport 22 -j ACCEPT

Also depending on how you have the server configured, you might need to add the ip address of the host your trying to connect FROM to /etc/hosts.allow

if your able to bring up a console on that server then try running sshd in debug mode on a seperate port ie

sshd -d -d -d -p 2020

then ssh to the server using
ssh -v -p 2020 ipaddress


note the output from both consoles somewhere it should give a clue to why it fails

o.k. now I am recieving a response from the server:
(I AM TRYING TO CONNECT FROM A LINUX RED HAT):

WHAT PASSWOED HE'S ASKING FOR ?
i TRIED THE ROOT PASSWORD AND HE REFUSE TO THAT PASSWORD. WHAN I TRY TO CONNECT TO THE MACHINE FROM A WIN 2000 WITH PUTTY CLIENT EVERYTHING WORKS.
WHY IN LINUX EVERYTHING IS SO COMPLICATED ?

Hi Juanb

The password requested will be the password of a local user on the box you are trying to access.
If mickey mouse had an acount such as mmouse, then add the following

-l mmouse

to the ssh command. When asked, mmouse can then type the password of that account.

thank u very much !!

Glad it helped.
