[lug] telnet problems

[Andrew Reberry]

Hello all.  I've got a strange problem I cant even start to figure out...

After installing a new distro (RedHat 6.2) I have found that I am unable to telnet into it.  I noticed that 'inetd' was not installed so I then installed it. ('rpm -i inetd-0.16-4.i386.rpm')  However, after installing 'inetd' I am still having the same problem.  When I try to telnet into the machine I get the error:

'Connection closed by foreign host'

This error comes up when I try to telnet in from the local network (192.168.2.*) or from localhost itself (127.0.0.1).  So I decided to check /etc/hosts.allow and hosts.deny.  I specify for all machines on the 192.168.2.* network and 127.0.0.1 to have permission to access the RedHat machine, and I made sure no computers are being denied access to the machine.

I have checked hosts.allow and hosts.deny.  I have installed inetd.  I have made sure that the following line exists in /etc/inetd.conf and is not commented out:

'telnet  stream  tcp     nowait  root    /usr/sbin/tcpd  in.telnetd'

I have even changed the string to specify the exact path of in.telnetd, which is in my /usr/sbin/ folder.  The line now reads:

'telnet  stream  tcp     nowait  root    /usr/sbin/tcpd  /usr/sbin/in.telnetd'

I have made sure I am not root when I telnet to the localhost.  When I try to telnet over the network into the machine I get the same problems.  I know it is not the network because I have samba working correctly, and I can ping all computers without any problems.  (plus I can't even telnet from localhost)

When I do a 'ps aux | grep inetd' I show inetd running on root just fine.  I have tried 'killall -HUP inetd' and that does me no good.  I have even checked the log files after trying to telnet and this is providing me with no output.

Any ideas would be appreciated.
