The other day I was farnarckling around on my linux box to try to get printing working to a HP network port. Now I cant telnet in via the internet. I know that's not necessarily a bad thing, but I cant ssh in either. I just get a "connection refused" error. If I am on a machine on the local network I can telnet in, but I cant do it via the internet. Has anyone got any ideas as to why this might be happening and where I might look?

Talk to your firewall administrator. Its possible that those things will have to be opened on the firewall to allow access to your machine from the internet. Most sites don't allow any internet access into local machines accept for downloads and HTTP unless explicitly identified on a machine by machine basis.

This may not be it, but its as good a place as any to start.

Good luck.

I just wanted to add that if your local machine is not using a public address you will probably have to ssh or telnet your proxy server or firewall and then ssh or telnet your local machine from there.

I posted an answer earlier it looks like it
is missing. Your firewall is probably
blocking port 23 which is used by both ssh
and telnet. Also if the machine is not using
a public address you won't be able to
directly telnet or ssh to it. Youwill have
to telnet or ssh to the firewall or proxy
first and then telnet or ssh from there.

P.S. I suggest you disable telnet and
strictly use ssh for obvious reasons
