using ssh

[kris.c]

After groping about for a long time, i have now realised that the best thing suited for what i am trying to do is "ssh"
I still have a problem. I have downloaded the tar-ball and correctly installed it on both my machines. I am still not able to log into my cluster machine through my slave.

Here are the details:
server machine :
IP : 192.168.1.100
Hostname : linux
Domain : site

Client machine:
IP : 192.168.1.10
Hostname : machine1

And what exactly should i type at the client machine to log into the server machine.?
This is what I have tried so far :
# ssh root@linux.site
didnt work
# ssh root@192.168.1.100
didnt work
and some other combinations. still no positive result.

Howdy kris.c!

Silly question, does your host.allow file on 'linux' have machine1?

Normally root logins over ssh are turned off by default, and this is the way you should try and keep it. When you log in over ssh, log in as a regular user and use 'su' or 'sudo' to do sysadmin stuff.

Make sure you have a regular user account on the machine '192.168.1.100' and do 'ssh <username>@192.168.1.100'. That should work a lot better.

Well, sorry about that , I am still pretty much new. But, I checked it up, it first scans "hosts.allow" and then "hosts.deny". If a match is not found in either file, the access is still allowed. So, my mistake is not there I suppose.

yeah, I did that too : # ssh <username>@192.168.1.100
it blinked for a long time before saying that the destination was unreachable.

I can "ping" one machine from another, so, connectivity is not a problem.

And the ssh daemon is running on both the machines too,

# ps -aux | grep sshd
root      4379  0.0  0.7   4700  1972 ?        Ss   22:26   0:00 /usr/sbin/sshd -o PidFile=/var/run/sshd.init.pid
1000      5668  0.0  0.2   2728   672 pts/1    R+   22:55   0:00 grep sshd

And,
>Make sure you have a regular user account on the machine '192.168.1.100'
The account I use to login should suffice right?


Prior to this , I had downloaded with ssh-3.0.1
I did the following as root on both the machines:

# ./configure
# make
# make install

I am sure nothing went wrong there too.
Please help....

well, I just found this :

and the problem was indeed with the firewall itself. I still have an issue with authentication, but atleast , i am not getting "destination unreachable" anymore.
Thanks.

Can you help me out:

# ssh <username>@192.168.1.100
Host key not found from database
Key fingerprint:
xipoc-kofur-ratag-gavup-sigec-cemub-kekof-gafan-tacut-reduv-roxox
You can get a public key's fingerprint by running 
% ssh-keygen -F publickey.pub
on the key file.
Are you sure you want to continue connecting (yes/no)? yes
Host key saved to /root/.ssh/hostkeys/key_22_192.168.1.100.pub
host key for 192.168.1.100, accepted by root Wed Dec 20 2006 23:07:58 +0530
warning: Authentication failed.
Disconnected; no more authentication methods available.

So, next i tried

# ssh-keygen -F key_22_192.168.1.100.pub
Fingerprint for the key:
xipoc-kofur-ratag-gavup-sigec-cemub-kekof-gafan-tacut-reduv-roxox

and for all the subsequest attempts :

# ssh <username>@192.168.1.100
warning : Authentication failed
Disconnected; no more authentication methods available.

what do i do to correctly login?
