Package: nfs-user-server
Version: 2.2beta47-25
Severity: normal

While configuring a vserver to be an NFS server, I installed
nfs-user-server, as nfs-kernel-server won't work within a vserver.

I had this in my exports:

/pub            *(rw,no_root_squash,async)

However, trying to mount /pub from 10.41.1.43 failed with the following
in syslog:

Mar 13 17:50:48 installserver mountd[27169]: NFS mount of /pub attempted from 
10.41.1.43
Mar 13 17:50:48 installserver mountd[27169]: Unauthorized access by NFS client 
10.41.1.43.
Mar 13 17:50:48 installserver mountd[27169]: Blocked attempt of 10.41.1.43 to 
mount /pub

I then tried using 10.41.1.0/24 instead of * , but same thing happened.
After trying a number of variations, I tried 10.41.1.0/255.0.0.0 and lo
and behold, that worked!

However, further experimentation shows that 11.41.0.0/255.0.0.0 also
works, and I can't imagine that's the expected behaviour...

Please explain how to limit access to those IP addresses starting with
10.41.1.


Thanks,
Paul Slootman
