Paul,

You might get more help if you posted to the list in Text format instead
of HTML or RTF or whatever....

With regards to the errors above, I don't understand what you mean when
you say "try to open a port"?  But I have a question that may shed some 
light on the issue...  Did you recompile the kernel with custom config 
options? Or are you using the standard RedHat 7.2 kernel?

If you are using the standard 7.2 kernel I would first suggest that you
update to the latest version of the kernel which I think is
2.4.18-18.7.x

That may fix your problem all by itself.

If you did the rhn_register then all you have to do is run "up2date"
and select the kernels, let it install and then reboot.
