Strange problem here. Two systems; Scorpio is the NIS client and Atlas is
the NIS master.
Specs
=====
Scorpio
-------
Ultra 10
Solaris 8 patched
hme0 = 172.25.209.158 255.255.255.0
the ypservers file contains 'atlas'
Atlas
-----
Ultra 2
Solaris 2.6 patched
be0 = 172.25.250.23 255.255.255.128 -> Atlasadmin
hme0 = 191.41.100.203 255.255.0.0 -> Atlas
Problem
-------
I am snooping on both Atlas and Scorpio.
When I run /usr/lib/netsvc/yp/ypstart on Scorpio I see the packets go to
and return from Atlas. I have included the snoops below (2 packets each).
The wierd thing is that Atlas puts the IP address of the be0 interface in
the RPCB section of the packet instead of the hme0 IP. Look at the RPCB
section of packet 2 in each snoop to see what I mean. Hence, Scorpio cannot
connect.
My netmasks are correct and all other traffic
(ICMP,telnet,rsh,rlogin,etc...) works fine. It appears that the NIS master
(Atlas) is looking at my IP address and seeing a class B (even though it is
subnetted out) and simply choosing it's closest match instead of seeing
what interface the packet came in on.
Any help would be greatly appreciated.
Thanks, Rick
