The "Can't bind to reserved port" error message looks like the known
problem when you set CONFIG_SECURITY. It has been discussed several
times already on l-k.
Please either disable CONFIG_SECURITY (it's not as if *that* is going to
be a showstopper when migrating to 2.6.x from 2.4.x) or go to my website
and apply the advertised fix:

Cheers,

Dear Trond,
thank you for the fast reply. I chose the first solution (unsetting
CONFIG_SECURITY)
as I don't have local security modules anyhow. and our problem disapeared.
Is there any reason to nevertheless install your patch?
Cheers
Willy

No: the patch solves just the one problem.

Looks nice. Will this go upstream, or is there still other issue?
thanks,

No known issues, so I expect it to go upstream RSN. I just thought it
would be convenient to make use of the fact that the Connectathon
inter-vendor testfest is on right now to give it some extra milage first
;-).
