Can′t do "telnet localhost 631". Why?

Post by Sangohn Christia » Fri, 01 Dec 2000 04:00:00



Hello!

I cant telnet to port 631 (ipp port) of my machine.
On other port (i.e. 25 (smtp) 119(nntp)) there is no problem.

What could be the reason I cant telnet to this specific port 631?

TIA

You probably don't have a service running on that port currently, which
is probably a good thing.

I don't know what ipp is or how it should respond, but if you netstat -a
do you see anything listening on port 631 or ipp?  Are you blocking it
with ipchains or anything?

ipp is the Internet Printing Protocol which is used by the CUPS (Common
Unix Printing System http://www.cups.org) to print over IP networks

1. Why would "telnet localhost" disallow connection?

Telnetting to "localhost" refuses connection!  If I type "telnet
localhost," I get, "Trying 127.0.0.1," then "Connection Refused." --
from my own machine!  Why is this?

I checked /etc/hosts.deny, it is blank (saved some commented text).

Note: I use bootpc to connect my ethernet to my university's network;
if I do not use bootpc, "telnet localhost" will work.

Does anyone know enough about bootpc to determine why it is causing
this?

Thanks,
Matt
