telnet problems

comp33 · 12-20-2001, 09:20 AM

New to Linux..........I can ping a Linux server but cannot telnet to it. Settings in /etc/inetd.d/telnet seem OK and telnet is enabled. I can telnet to the server from itself fine which indicates 'telnet' is running. I just can't connect to it from another machine.

Running Red Hat 7.1 and trying to connect from a Win NT 4.0 machine. Any help would be great!:smash:

i take it you've not bothered to search this forum at all?

change the line in /etc/xinetd.d/telnet
for
disable = yes
to
disable = no

oh sorry that is a bit rude isn't it? :-S

can you connect via other services such as ssh? i would guess that if you can connect locally.. as i would have seen if i read the q properly... then it's a firewall thing i'd guess.

Well he said he can connect to it from the server itself, so I doubt it's disabled. It's probably the default firewall rules of redhat which are blocking telnet access. Try changing your firewall rules.
But anyways I'm sure a search on this forum would bring up lots of results and maybe give you the solution.

You can drop any firewal rules by doing the following

ipchains -F
or
iptables -F

Many new distros are coming with built in firewalls, RH7.1 is definately one of these distros.

cpare, great suggestion! i've been searching high and low and now realized that the default firewall software that came with 7.1 was blocking my telnet, ftp and NIS sessions.

now i can wreck some more havok....
