SSH into RH 7.3 refused
 

Hello,
I am trying to ssh into my rh 7.3 machine and it is refused each time. I have tried using putty and my rh 9 machine.

I have done an nmap on the 7.3 machine and port 22 is open. Does anyone have any ideas? Thanks alot.



*edit* i don't know how much this matters but i am able to ssh from the 7.3 into the 9 *edit*

Have you added the remote system to /etc/hosts.equiv?

There is no such file, and is there some reason that i should create one? Neither one of my RH machines have that file on them. The RH 9 has no problems what so ever

Hmmm. I just now set up ssh on my machines and read somewhere (webpage) that you needed entries in hosts.equiv. But after reading your post I renamed the file on one and ssh still works.

Must have been obsolete information. Sorry, I can't help you any further then.

John

oh well thanks for trying :)

Ok .. i have made some progress.... turns out when i do a

nmap localhost

on the 7.3 machine it shows that 22 is open along with some others. However when i do an nmap from a different computer

nmap 192.168.1.104

it only shows one port open 1024


so its some kind of firewall issue as far as i can tell. i have done some looking and i am finding out to change my iptables config file, but there is no such file. What i found that was close and appears to be similar is an ipchains file. I am wondering if the ipchains in the /etc/sysconfig is the correct file that controls the firewall or not.

Yes, you have a firewall problem. You need to open port 22, at least to the computers you want to SSH from.

Another way to change firewall rules is with Webmin. webmin.org

where is the config file for that?

or how can i even turn it off?.... i am behind a router so i am going to have to port forward anyway so it might be easier to just turn it(the firewall) off for the time being.

Just try doing "/sbin/ipchains --list" to list your firewall configuration.

To flush your chains (get rid of them, and not have ANY firewall), do:
"/sbin/ipchains --flush"

Yes, the config file should be /etc/sysconfig/ipchains I believe. This worked fine for me in RH7.3, and I have now upgraded to RH9

"/sbin/ipchains --flush"


did the trick .... thanks so much

ssh is working fine... now off to config ftp and finish doing samba
