I can't ssh to a server from any machine on one particular LAN - here's
the debug:

OpenSSH_4.2p1 Debian-7ubuntu3.1, OpenSSL 0.9.8a 11 Oct 2005
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug2: ssh_connect: needpriv 0
debug1: Connecting to salford.zen.co.uk [62.3.91.113] port 22.

debug1: identity file /home/mark/.ssh/id_rsa type -1
debug1: identity file /home/mark/.ssh/id_dsa type -1
ssh_exchange_identification: read: Connection reset by peer

I can connect to this server port 22 from a different LAN; I can also
telnet to the server from this LAN.
The debug is from an attempt from an Ubuntu box; I normally attempt to
connect from XP using putty, and get a 'Network error: software caused
connection abort' error.

That error is characteristic of a connection that is dropped by tcpwrappers so you might want to check the hosts.allow and hosts.deny files (usually in /etc/ or /usr/local/etc/ depending on how it was built).

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
