Networking problems, linuxppc2.4, RPX CLLF, Montavista

[Joakim Tjernlund]

Hi all

I have this strange network problem and I can not figure out whats wrong.

I running linuxppc2.4 from Cort's tree on a RPX CLLF(cpu PPC860T) and a file
system
from the Montavista CDK 1.2(with the latest updates). I NFS mount my root
fs, created a
local user(I can login on my local user). Ping works both ways(from RPX to
my Linux host
and vice versa).

But I can not telnet or ftp from my linux host to RPX, I get "connection
refused"(inetd is
running on RPX) and if I telnet(or ftp) from RPX to my Linux host it takes
1-2 minutes
until I get a login prompt.

BUT if I boot the 2.2.14 kernel that came with the Montavista CDK 1.2
everything works!

I have no idea what I am doing wrong. I have searched all www & mailing
lists I can think of
but I seem to alone with this problem.

Please help.

Jocke,

You can try adding /bin/strace before /bin/telnetd in your /etc/inetd.conf file on the target, so the line looks like:
telnet stream tcp nowait root /bin/strace /bin/telnetd telnetd -L/bin/login
Then try to telnet to the target.  See what files it's reading, etc. before it boots you off.  This may point you in the right direction.

Thanks!

This solved my problem. I saw that ip address 127.0.0.1 was used in
a telnet session and that made me to look over my dhcp server conf.
Once I gave my board a real hostname and removed the nis domain option
things started to work!

It seems that 2.4 needs a real hostname(2.2 does not) to operate
correctly. If no hostname is specified in the dhcp conf, Linux will
use the IP address as hostname and dnsdomaninname.
