Slow ssh connections

When I try to telnet from my Gentoo box to my Debian box this is what happens:

# ssh debbox

* -- pauses here for 60 seconds or so ---*

daniel@debbox's password:

After I enter my password, everything is fine.

My flatmates windows box, and my other 2 debian boxes can log in fine, so the problem must be my Gentoo box.

Anyone got any ideas ?

Well you are not really telnet-ing into the other machine are you, you are ssh-ing.

But to the problem
This is caused by the respective ssh client and server not using matching protocols, causing a thourough security check. Try upgrading the version of ssh on the server.

Windows boxen work quickly because the security isnt authenticated properly

It could be that you run into a dns timeout during the reverse lookup made by your debian box when you try to login from your gentoo box? 60s looks like a dns timeout for me.

It does sound like a dns timeout, it would be worth your while to setup an internal DNS server, or even simpler still would be to add each of the machines ip addresses and hostnames into the /etc/hosts file on both machines.

edit the /etc/hosts on your debbox, and add the name for your gentoobox, and the corresponding ip adres.
ssh, telnet, ftp are a few services that will do reverse namelookup's
If that fiales, the service will continue.

To speed up things within any linuxnetwork (in a windowsnetwork too) be sure that nameresolution and reverse namelookup works on al the machines, to al the machines.
