Linux and in.telnetd problems

sam_pointer · #1 (**permalink**) 08-30-2001

Hi,

This is not the usual "unable to telnet to my machine" post. I:

* have ensured that in.telnetd is started from inet.conf

* that hosts.allow/deny are correctly configured

* in.telnetd is listening, and on the correct port

When I check my syslog i notice that tcpd (as I have in.telnetd running under tcp_wrappers) has 10 seperate entries (with ten seperate PIDs) proclaiming "exit status 1".

I am assuming that this is in.telnetd exiting in error. I cannot telnet to myself.

I have a hunch that this might be concerned with verifying the calling host

Now, my question is this: does in.telnetd (or tcp_wrappers for that matter) attempt to do some kind of DNS lookup on the calling host to verify the entry in hosts.allow/deny?

Can I put IP addresses in hosts.allow/deny to avoid this DNS lookup or otherwise turn it off?

Anyone else got any ideas?

Thankyou very much in advance!
