Hi,
I just installed Linux on a box and am having troubles getting it configured properly for the network. I'm running Mandrake 9.1. I've put it on my network at work and can ping my Windows box from the Linux box. I can get out onto the internet. I can telnet into a Sun box from the Linux box. But, I can't see the Linux box on the network. I tried to have it ping itself, with no luck:
ping localhost
100% packet loss
Here's the results of ifconfig:
eth0 Link encap:Ethernet HWaddr 00:04:75:86
7:5A

WAIT!!! HALLEELUIA! I fixed the ping problem. In the file /etc/sysctl.conf I commented out the line net.ipv4.icmp_echo_ignore=1 and replaced it with net.ipv4.icmp_echo_ignor = 0
So, I can ping the linux box. WOO HOO!!!!
I still can't telnet to it. Here's what I've done to identify problems using telnet:
ps -ef | grep inet
root 10569 1 0 15:17 ? 00:00:00 xinetd -stayalive -reuse -pidfile /var/run/xinetd.pid
So, the daemon is up that should listen for telnet sessions, so what's the deal? What can I do to identify the problem?
Thanks,
