NFS and SUSE 9.0

[Collins]

I've never used NFS before, so perhaps some of you network gurus could clue me 
in on the results described below.  Is this a peculiarity of SUSE, or is this 
pretty normal for NFS these days?  I haven't found any google references that 
specifically address the port usage I'm seing.

First the setup:

1. sys4 a standard SUSE 9.0 box, no firewall yet, on my round-tuit list.  I 
will decipher and use the standard SUSE firewall offering.

2. sys3 a gentoo box with Shorewall firewall.

My desire is to have a work partition writable from either box and the root 
filesystem of each box readonly across the lan.  A few wrinkles, but this is 
up and working.

The first obstacle to over come is that gentoo and SUSE use different uid 
origins (500 for SUSE, 1000 for gentoo) for normal users.  So, I altered my 
gentoo users uids to match those on the SUSE box.  Of course, I hasd to 
eliminate some trash in /tmp associated with the old uids before I could run 
gnome/kde again.

After some experimentation, the only way I could get the desired results on my 
work partition (supposed to be writable by anyione) was to make this owned by 
nobody.nogroup.  There may be a more elegant solution, but this works for 
now.

My root partitions are exported with (ro,no_root_sqwuash, sinc) and this works 
as desired.  

Since the gentoo system is firewalled, I had to open up the desired ports.  
Per the Shorewall instructions, this is 111 (tcp/udp), 2049 (udp), and 
32700... (udp).  Well, the rest of the story is that the SUSE system issues 
some other requests (seems to depend on phase of the moon or chicken bones).  
When issuing mount 192.168.0.3:/ /mnt/root3 (i.e. view my sys3 root 
filesystem from sys4) I got different results on different days.  First I had 
to open up 744 (udp).  According to the standards this is something called 
Flexible License Manager.  Then the next day I had to also open up 615 (tcp, 
udp).  According to standards this is sco-inetmgr Internet Configuration 
Manager.

Are these ports now a normal part of NFS interchanges, or is this something 
wierd that SUSE offers.
