Referral in NFSv4

[Juilee Hapse]

Hi,

  Of the things you asked...
1. Can you do a normal v4 mount of dfswin1:/vicepa?
 --> yes this can be done.

 2. firewall issue.
--> firewall is disabled on all 3 m/cs ( 2 servers and one client)

 3. Network trace.
--> Have taken one through wireshark. Attaching that file.

 4. Versions of client and server:
---> server is 2.6.18 (both the servers)
---> client 2.6.20

Also attaching the logs for  client/server output of :
#tail -f /var/log/messages


Thanks,
Juilee
