by pressing the up arrow...

When I'm logged in as root and I press the up arrow to go back in the command line history, I get disconnected (see screenshot)


When logged in as user demo, the deconnection does not happen.
I'm running Ubuntu 8.10 and I haven't tried yet from the Uni. I won't be there until monday.

I'm currently doing the firewall tutorial.

Not sure it comes from the VM or not: 8.10 is still a young version and is still quite buggy...

I might add also that since I've moved over to the DNS tutorial, it doesn't happen anymore...

I have never heard of this happening before. It would be lovely to capture the packets involved and see what was really happening. However, it is likely a bug in your telnet program... I am told it also happens to some xp telnet clients.

One solution is to use putty. Google putty and download putty.exe. It is a stand-alone executable and does telnet as well as ssh. I recommend it 100%. You can use ssh with

Another option might be to change the terminal type when you log in. Try typing this each time you log in:

$ export TERM=vt100
$ tset

If the problem persists with this setting then I am out of ideas. It has never happened to me.

Thanks! It's been fixed apparently. I've just been through the firewall tut again and didn't encounter any probs.
Thank you for your time!
