Super high port numbers in the millions


Dear Gentle Folk,

A am running Centos 5.3 on nummerous machines and
SunOS 4.1.4 on one.

I export a directory from SunOS to Centos, then
I mount the sunos directory on the centos machine.

All of the files are there, but all of them are
unreadable. using nfsvers=2 in the mount.

When I do a tcpdump, I notice that the centos
machine is sending packets TO port 2049 on the SunOS
machine, FROM 3 billion or more on the CentOS machine.

No other application seems to do this and all
work fine from Centos -> SunOs except mount and nfs.

What exactly do I not understand about the phrase that port ranges are 0 to 65xxx?

Thanks in advance,

Homer W. Smith

I do not think even tcpdump can handle those irreal port numbers.
