MEPIS / ssh

rjcrews · 02-07-2006, 05:47 PM

Hi i just installed MEPIS and am having some problems getting ssh to work..

i added
iptables -A INPUT -p tcp --dport 22 -j ACCEPT

this did not work
I turned off guarddog/iptables, this does not work. i used the same config as on my other puters, still not working.

Any ideas ?

only the obvious one of asking if sshd is running.

what is your error message?

pljvaldez · 02-07-2006, 06:13 PM

Try typing, as root, /etc/init.d/ssh restart to see if ssh is running. (or look in /etc/ssh directory to see if sshd_config file exists). Otherwise, sshd is not installed.

Actually the only thing i can tell that is different from my other boxes, is that netstat shows

tcp6 ::::22

the tcp6 could be the problem?

I have restarted ssh , no errors when i do so.

satinet · 02-07-2006, 06:22 PM

ps -ef|grep -i sshd ???

can you ssh from the box to itself...

tcp6? what is the netstat output?

Also, I can ssh to other computers from this one.

pljvaldez · 02-07-2006, 07:10 PM

Try ssh user@localhost, of course, putting in your username (root login is probably disabled by default).

rjcrews · 02-07-2006, 10:20 PM

I am able to login in

Code:

ssh user@localhost

The tcp6 seems strange to me though, i am unable to find out how to change this. Also
I read
http://www.linuxquestions.org/questi...highlight=tcp6

and

http://www.linuxquestions.org/questi...highlight=tcp6

and was unable to determine an answer for my problem..Is there any other reason I would be able to log in locally but not remotely?

I have turned off iptables (iptables currently block my ftp access so i can tell when they are off)

I have hosts.allow and hosts.deny in order also.

ifconfig for lo has the inet 127.0.0.1 line...

i tried the netcat -l -p 22 and have no traffic at all.

thanks again

rjcrews · 02-08-2006, 09:32 AM

I disabled the ipv6 stuff in /etc/hosts
so now netstat shows regular tcp 0.0.0.0:22 for listening, no ipv6. I am going to assume i have some other problem here..

thanks for the help.

satinet · 02-08-2006, 05:12 PM

does it refuse connections or time out?

rjcrews · 02-08-2006, 10:00 PM

it was timing out and refusing (i was changing stuff). after i commented out the ipv6 stuff, changed some other crap around, it worked.

the nc -l -p port# from that other post really helped me trouble shoot it though..

really not sure what i did.

thanks for the help/ideas

lefty.crupps · 02-09-2006, 05:55 PM

is it blocked in GuardDog (firewall)?

rjcrews · 02-09-2006, 06:59 PM

the first thing i did was turn it off, so this was not the problem. Although im sure I am going to have problems getting it set back up
