Re: Telnet Problem

Hi,

I know telnet is not secure, that is not the problem.

I set up a telnet server on a Fedora 7 Linux system using xinetd. I
believe I have all the configuration files correctly set since I can
successfully do:
$ telnet localhost
and establish a successful telnet connection on the same machine where the
telnet server is running.

Xinetd is running and my /etc/xinetd.d/telnet file is:

# default: on
# description: The telnet server serves telnet sessions; it uses \
# unencrypted username/password pairs for authentication.
service telnet
{
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/sbin/in.telnetd
log_on_failure += USERID
disable = no
}

The problem is when I try to connect to the telnet server from one or more
client computers on the same local network. Here is what happens.

$ telnet 192.168.0.100
Trying 192.168.0.100...
Connected to 192.168.0.100.
Escape character is '^]'.
getnameinfo: localhost: Success
Temporary failure in name resolution: Illegal seek
Connection closed by foreign host.
$

Firewalls and SELinux are off. I always connect with an IP address, not a
fqdn. I can access the telnet server computer with ssh and ftp.

I would appreciate help.

Thank you,
Joe Hesse


I appreciate everyone's help. I managed to fix the problem and feel
embarassed that I didn't recognize the problem sooner. Here is the summary.
1. I removed a Windows XP computer from my network and rebooted everything
else. Telnet worked great!
2. My virus protection expired from Windows so I subscribed to a new virus
service, found a "High Threat" virus and removed it.
3. Telnet works great, from Windows to a telnet server or Linux to a telnet
server.
Thanks,
Joe
