Kristina,
As you may have seen by now, you hit the nail on the head - I realised after I'd disconnected my (email) laptop and just did a quick test before going out of the door for the weekend to confirm it.
Thanks,
/Sam

Just a thought... if you can't telnet to the box -- are you sure that
telnetd is running and listening on the port you are expecting it to be?

- I want to use iptables. Both iptables and ipchains are defined (and
- ticked, for my fellow pedants!) in the Services list, but when I tried ipchains -L I was told ipchains: Incompatible with this kernel (so how come it's in the services config?!).

- iptables -L shows me the three (default, I guess) chains INPUT FORWARD and OUTPUT,
- each with a policy of Accept and no rules, so I would have thought that
- this would allow me to telnet from another address on the same subnet. Not
- so - I can ping both interfaces, which are temporarily on the same network
- but can telnet to neither. It appears that ipchains is somehow preventing
- access.
-
- So, other than rebuilding with no security, how can I disable ipchains and
- start to build my iptables tables?
