Well, I'd say it's a bit strange it didn't ask for a password. You could start with connecting as user at the server to the server via ssh just to check that it works. Then try the same from the client. To find out if you're connected you can just do a ll to list files, I suppose you know what files you have on which computer. Or do uname -a or whatever. Did you manage pinging as Baldyeti suggested?
If you get connected I suggest you try with fish next.
Let me just run a sample to show how ssh works.

I'll start it with:
root@fujibox:~# /etc/init.d/ssh start
Starting OpenBSD Secure Shell server: sshd.

Then check that it's waiting for a connection:
root@fujibox:~# nmap localhost

Starting nmap 3.55 ( http://www.insecure.org/nmap/ ) at 2004-08-21 19:47 EEST
Interesting ports on mrk-fujibox (127.0.0.1):
(The 1659 ports scanned but not shown below are in state: closed)
PORT STATE SERVICE
22/tcp open ssh

Nmap run completed -- 1 IP address (1 host up) scanned in 1.260 seconds

Or with:
root@fujibox:~# netstat -tap|grep LISTEN
tcp6 0 0 *:ssh *:* LISTEN 5047/sshd

Then connect as user:
markus@fujibox:~$ ssh -l jarkko fujibox
Password:
Linux fujibox 2.6.6-16.06.04 #1 Wed Jun 16 22:14:41 EEST 2004 i686 GNU/Linux

No mail.

jarkko@fujibox:~$ logout
Connection to mrk-fujibox closed.
markus@fujibox:~$

I stop it with:
root@fujibox:~# /etc/init.d/ssh stop
Stopping OpenBSD Secure Shell server: sshd.

And it's stopped:
root@fujibox:~# nmap localhost

Starting nmap 3.55 ( http://www.insecure.org/nmap/ ) at 2004-08-21 19:53 EEST
All 1660 scanned ports on fujibox (127.0.0.1) are: closed

Nmap run completed -- 1 IP address (1 host up) scanned in 1.211 seconds

Hi Marcus.....OK I did what you suggested but it seems to hang up when i try to log in to my laptop...heres what comes up:

Bob@Home:~$ su
Password:
root@Home:/home/Bob# /etc/init.d/ssh start
Starting OpenBSD Secure Shell server: sshd.
root@Home:/home/Bob# nmap localhost

Starting nmap 3.50 ( http://www.insecure.org/nmap/ ) at 2004-08-21 13:07 EDT
Interesting ports on Home (127.0.0.1):
(The 1651 ports scanned but not shown below are in state: closed)
PORT STATE SERVICE
22/tcp open ssh
53/tcp open domain
68/tcp open dhcpclient
111/tcp open rpcbind
904/tcp open unknown
919/tcp open unknown
953/tcp open rndc
2049/tcp open nfs

Nmap run completed -- 1 IP address (1 host up) scanned in 0.815 seconds
root@Home:/home/Bob# ssh -l Bob Gateway

OK heres where it just displays a blank line after I log in, right above here^

Am I logging in right? Something seems funny here. My Hostname for desktop [server] is Home
and my Hostname for laptop [client] is Gateway

The prompt doesnt look right or something.....well i seem to be progressing a little anyway! I logged in by typing:

root@Home:/home/Bob# ssh -l Bob Gateway

Is that right?

You want to log in to the server, right? Then you need:
ssh -l login_name_as_user_on_server server_name
As I understood you configuration it would be:
ssh -l Bob Home
And you don't want to login as root!

**bob58** · 08-21-2004, 06:29 PM

Hi again Marcus! Wow this is HARD!!! lets see....OK I am not sure what I am doing.....I did the following from the desktop:

root@Home:/home/Bob# ssh -l Bob Home
The authenticity of host 'home (127.0.0.1)' can't be established.
RSA key fingerprint is 37:3a:a0:11:d6:f5:25:21:3e:5b:8e:7c:7c:95:30:11.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'home' (RSA) to the list of known hosts.
Password:
Warning: No xauth data; using fake authentication data for X11 forwarding.
Welcome to Knoppix (Kernel 2.4.26)

Bob@Home:~$

Not sure what this means.....Am I logged in to the desktop computer via ssh to myself???? I dont know what to do here! It seems there was some kind of error but i seem to be logged in to myself...it did ask for password this time. OK so i dont want to do this as root....OK...so I am now at "Bob@Home".......sorry to sound so confused.....well one step at a time....what are your thoughts at this point? bob58

**Markus** · 08-21-2004, 06:32 PM

Well, the connection worked and now is the time to try it from the client with the exactly same command, or try with IP instead of Home if it doesn't work.

**bob58** · 08-21-2004, 06:56 PM

Hi Marcus....OK let me start at beginning as I am now more confused than before. I apparently need instructions for a MORON cause I am missing something! I will do this by numbers:
1. bring up Konsole on Desktop Computer
2. log in as Root and do: /etc/init.d/ssh start
3. That brings up "starting open BSD secure shell server"
4. I did "nmap localhost" to check if its waiting for connection.
5. This is where I am confused: connect as user: "ssh -l Bob Home [or IP if Home does not work]....But why do I want to connect to Home [server, or desktop] when I am already on that computer? If I go to laptop [client] and try to do the same once I have done it on desktop, it just does a carraige return to a blank line and if i type in something, and i am not sure what to do at this point, it just returns to a blank line.
6. so do i type in " /etc/init.d/ssh start" on Desktop computer to begin with.....then go to laptop and type in "ssh -l Bob Home" to connect to the desktop? if i do this i get blank lines after the command. And it doesnt ask for password.....

**bob58** · 08-21-2004, 07:16 PM

This is what I get when I "ping" the laptop [198.168.1.102] from Konsole from Desktop:

Bob@Home:~$ ping 198.168.1.102
PING 198.168.1.102 (198.168.1.102): 56 data bytes

And I get the same thing when I "ping" desktop [198.168.1.100] from laptop

As far as using "fish" and Konqueror" I have not succeeded. I may need more detailed instructions.....The main problem is I cant connect as user to one computer from another, but there apparently seems to be a connection of some sort....When I connect as user, I do this:

ssh -l Bob Home which seems to work when I do this from the desktop to connect as user to myself....it asks for password and goes to a command prompt....but I dont know what to do with it from there.
But if I try the same thing on laptop, seeing that I can connect to myself on desktop, I type in the same command : " ssh -l Bob [username on both computers is the same] Home to try to connect to desktop, but i get a carraige return and blank line and anything i type in at this point returns a blank line!!!

**OErjan** · 08-21-2004, 07:16 PM

froom the client computer the comand below works for me:

Code:

ssh username@ipnumber

as yoiu mentioned fish:

Code:

fish://username@ipnumber/home/username

works.
ipnumber is replaced with
192.168.1.100 for the laptop (which i assume is the client)
and
192.168.1.102 for the desktop (which in turn is the server)

So far so good.

5. This is where I am confused: connect as user: "ssh -l Bob Home [or IP if Home does not work]....But why do I want to connect to Home [server, or desktop] when I am already on that computer?

This was just to check that the connection to the server works.

If I go to laptop [client] and try to do the same once I have done it on desktop, it just does a carraige return to a blank line and if i type in something, and i am not sure what to do at this point, it just returns to a blank line.

Something wrong there, it should work just as it did when you tried it on the desktop->desktop connection.

6. so do i type in " /etc/init.d/ssh start" on Desktop computer to begin with.....then go to laptop and type in "ssh -l Bob Home" to connect to the desktop? if i do this i get blank lines after the command. And it doesnt ask for password.....

Perhaps you didn't wait for long enough, sometimes it takes a while, although it shouldn't.
Did you manage to ping your desktop from the laptop?????

EDIT: Rats, I was too slow at typing

If the username is Bob on both computers you can just use ssh IP
