Hi,
I suffer from a problem, where my diskless environment doesn't work anymore
after upgrading the server from openSUSE 11.0 (2.6.25.20) to openSUSE 11.1
(2.6.27.21).
The diskless environment gets set up with an customized initrd via pxelinux.
The initrd uses klibc's nfsmount, and I've tried both protocols: udp and
tcp. It's not an iptables issue, since I can mount these directories from
other (fully booted) systems just fine.
Using the debug version of klibc's nfsmount prints these messages:
short read: 0 < 28
Port for 100003/3[udp]: 0
short read: 0 < 28
Port for 100005/3[udp]: 0
NFS params:
server = xxx.xx.xx.xx, path = "/roroot", version = 3, proto = udp,
mount_port = 627, nfs_port = 2049, flags = 00010282,
rsize = 0, wsize = 0, timeo = 7, retrans = 3,
acreg (min,max) = (3,60), acdir (min,max) = (30,60),
soft = 0, intr = 1, posix = 0, nocto = 0, noac = 0
tcpdumping the communication shows, that for whatever reason, the client
sends the mount request from source port 798 to destination port 627, but
the server doesn't listen on 627:

I've attached the relevant tcpdump section.
I would be very grateful, if some kind soul could enlight me here, as I'm
fully puzzled..
