hello all,
since few days, i've got an issue with machines name resolution on the
nfs server.
The nfs server (servA) is a NIS client (solaris 10 sparc 11/08), and
directories are shared with netgroups constraints. The nis map netgroup
contains all clients names (not fqdn names). It worked.
But now, nfs clients can't mount the shared dirs, because the nfs server
see requests from clientA.my.domain.fr instead of clientA:
servA-root% snoop clientA
Using device /dev/e1000g0 (promiscuous mode)
clientA.my.domain.fr -> servA TCP D=111 S=658 Ack=3984864805
Seq=4069484885 Len=0 Win=7136 Options=<nop,nop,tstamp 1599660880 10605740>
servA -> clientA.my.domain.fr MOUNT3 R Mount Permission denied
When i use getent, i got the correct name:
servA-root% getent hosts clientA
192.168.0.219 clientA
/etc/nsswitch.conf contains:
hosts: files nis dns
ans /etc/resolv.conf:
domain my.domain.fr
nameserver 192.168.0.23
The only thing i notice is that if i suppress /etc/resolv.conf, it works
. But in this case, this is sendmail that become broken!
What is the right way to have nis resolution working?
thanks in advance,
gerard
