Network timeout problem with samba

[Munikrishnaiah Bade]

Hi,

   I have a Linux client accessing a share from FreeBSD server. I mounted
one
of the share using smbmount. I have a process doing read/write to a file in
the
mounted file sytem(smbfs). When i unplug the network cable my process hangs
for about 15 minutes and fails.

    If i recconnect the cable after 10 min. The test process continues
read/write.
I want my test process to fail immediately after unplug the network cable.

   Is there any configuration parameter that i can use to make this timeout
less than
15 min. I used TCP socket option NODELAY in smb.conf as well as setting file
descriptor O_FNODELAY after opening it. Still getting the same result.

Any help?
