I am starting to learn how to use a secure shell to log into another computer and either run an application on the remote computer, displayed locally, or to do some work on the remote computer.

 

I started with some help from gemlog on the Linux Internationals Forum, here : --

http://linuxinternationals.org/phpBB3/viewtopic.php?f=123&t=2300&p=17004#p17004

 

I checked and found that I already had the sshd installed, called openssh-server.

So that was my first ssh session!

 

Next to try this from another computer on the network.

From ArtistX 0.6 to Ultimate Edition 8.10 on TestBed

 

I was able to set up and start SSHD on the TestBed computer, under  Ultimate Edition 8.10, and then SSH in using this code : --

 

paul04@paulArtistX:~$ sudo ssh paul@192.168.0.5

 

Then pass the password, whereon I was in! I was able to do many things via the CLI as if I was logged into the computer directly. It was also very fast, due to being text-only.

 

paul@paul-testbed:~/Documents$ exit

I tried just now to get into my pendrive from another OS on the LAN and succeeded with a password.

When I tried to use 'gksu gedit' I got the usual error message, unable to ,,, so I tried 'vi' with success. However using vi is not so userfriendly!

I have this evening, again, used ssh to connect between my ASUS computer and the Test-bed computer.

 

I remotely installed tightvncserver to the test-bed computer and ran a couple of sessions with krfb on my ASUS and krdc on the test-bed computer.
