SSH Connection


Hello All,

I have installed SuSE Linux Enterprise Server 8 OS.

I am trying to connect to other box (Sun Solaris 5.5) by using ssh.

When I tried to connect get the following message:

oracle@dawar:~> ssh 150.200.100.00 (fake IP address)
2080: ssh: connect to address 150.200.100.00 port 22: Connection refused

what I need to do?


I can ping successfully to 150.200.100.00 from SLES8.

Please note ssh is installed on SLES 8.

oracle@dawar:~>rpm -qa | grep ssh
openssh-3.4p1-105

Regards,
D

Is sshd installed and running on the Solaris system? I don't recall Solaris 5.5 having SSH included.

On a Solaris 5.5 system, unless you installed it, it's not there. If you did install it, then look under /usr/local or /opt for it. Check "ps -ef | grep sshd" to see if it's running. If not, go grab it from sunfreeware.com.

Is sshd using libwrap to filter connections or being launched via inetd/xinetd? Check your hosts.allow and hosts.deny files. Also if you have a firewall, check that config also.

Do you have a firewall between the sun box and Suse or any one of the machines.

I too dunn remember Sun 5.5 coming with sshd.

If you fell the sshd is running fine then the best way to test would be login to the sun box and try

#ssh localhost or
#telnet localhost 22

See if you get a proper output here then the sshd is running fine on the sun box and then it may be a firewall issue

Else you need to check the sshd config file and make sure it is running on sun box 5.5.

Assuming dhs3 is your machine then first and foremost you do not have a ssh client running on it.

putty is a great ssh and telnet client.

You do not need root access to the SUN box to check if sshd is running.
Just login to box as you would normally do and then do

$telnet localhost 22 and see if it gives you some o/p.

or

$ssh localhost to see if it works fine.

Do I need to relace word localhost by host name or type as

$telnet localhost 22

OR


$ssh localhost

if I do not have ssh on sun box why I am getting o/p

from following command

dn3 68: ps -ef|grep sshd
oracle7 23642 23241 0 10:25:03 pts/4 0:00 grep sshd

Thanks for your quick responses.

sshd is not running on the host dn3.

First if you need to ssh from dn3 to sun box

1. Get a ssh client for yourself.

2. Ask your sys admin on the way he has allowed access to the sun box.

Sorry it was typo error dn3 and dhs3 is for sun box.
It should be dhs3

So it is:

dhs3 68: ps -ef|grep sshd
oracle7 23642 23241 0 10:25:03 pts/4 0:00 grep sshd

For linux is as follows:

oracle@dawar:~>rpm -qa | grep ssh
openssh-3.4p1-105

Just shows that you're running the grep command and looking for sshd. It does not show an sshd process. If you want to do this a little more correctly (and prove to yourself that sshd is not running) do this instead:

$ ps -ef |grep sshd|grep -v grep

That will show you all the processes running that have "sshd" in their command line but do not have "grep" in the command line. You'll get no output when you run that command, thus proving that sshd is not running.

Ok,

I do not have SSH.


dhs3 145: ps -ef|grep sshd|grep -v grep
dhs3 146:

Do I need to install ssh client on only sun box?
Is it correct?


For linux is as follows:

oracle@dawar:~>rpm -qa | grep ssh
openssh-3.4p1-105

If you are trying to SSH from SuSE system to Solaris system, then you need an SSH client on SuSE and a SSH server on the Solaris. Did you login to the Solaris system via another method (ie console or telnet) and verify that sshd is running (if you have it installed)?

If it is not installed then you'll need the assistance of your system administrator since you stated that you do not have root access to the Solaris system.
