The server has many NIC's - and thus each NIC has its own address (and

Thus, I have limited the address that openafs uses using a NetInfo file
(in /usr/afs/local and in /usr/vice/etc).

The NetRestrict file would remove unwanted addresses. The NetInfo
file adds addresses that otherwise would be unknown.
See the man pages. http://www.openafs.org/manpages/
That man page does not agree with my recollection of how the software
actually works. Since I just checked the code and my recollection
agrees with the code, the man page is wrong.
The NetInfo file restricts the set of interfaces that can be used, and
has the behavior Deon expects. If a NetInfo file is present, then
only addresses listed in it are advertised, period. If a NetRestrict
file is present, then addresses contained in it are _not_ listed. If
both files are present, then both sets of restrictions apply.
Further, even if an address is listed in NetInfo, it is not advertised
unless it also appears on an interface or is prefixed by 'F'.
Does the man page need to be corrected, and if so, what needs to be
changed?
I think the man page needs to be corrected to say what I said, and the
NetRestrict page may need a similar update. I'll give an alternate
explanation; feel free to use any text you want from either...
When any of the components that uses these starts, it collects a list of
network interfaces from the OS. If the NetInfo file exists, any addresses
not listed there are removed, and any addresses prefixed with an 'F' are
added, even if there is no interface with that address. Then, if the
NetRestrict file exists, any addresses listed there are removed. The
resulting list is used for the addresses the CM advertises to fileservers,
or the address the FS registers in the VLDB, or the addresses a Ubik server
advertises to its peers.
