Default telnet

Hi everyone,

I suspect the ISP has blocked port 25 of the IP I used, so I would like to
test it from a host outside the ISP network. Does any one know where I can
find a free telnet login account such that I can ping and traceroute back to
my server to confirm it? Or any other newsgroup appropriate for this
question?

Appreciate for your reply.

Rgds,
wd

Surely you would want to telnet to port 25 on your IP. Pinging or
traceroute wouldn't tell you whether or not port 25 was being blocked.

If you give me your IP I'll run nmap on it and tell you everything I
can see ;-)

select shieldsup, and do a custom port probe for port 25.

Your IP was in the headers of your posting, so I thought I'd check for
you. Either:

a) That's not your IP, you're using another machine.
b) You have the machine disconnected/shutdown.
c) You have a *very* tight firewall (good for you!)

In any case I can't connect to port 25, or anything else.

If you want me to try again at a specific time, just email me.
