Lose shared network resource

Lose shared network resource

[Francesco Alfano]

Hello, 
I have a problem with the (exported) sharing of network resources. 
Initially i've used a sever with RedHat 7.3 kernel 2.4 now i've  installed 
Scientific Linux 5.5 with kernel 2.6.18-194.32.1.el5PAE with  Samba version 
3.0.33-3.29.el5_5.1. 

The problem is that I lose the network connection periodically, about 10  
minutes! 


I initially thought the problem was caused by a misconfiguration of  samba 
version of sl, that I installed on a client machine with windows  2000 the 
"Microsoft Windows Services for Unix" in order to use nfs connection  exported 
from linux server, but the problema arise equally. 


It's a serious problem for me because the disconnection of a mapped  drive on 
w2k (connected via smb or nfs) is causing the crash of a basic  application that 
tries to detect the presence every second of a new file  in shared resource. 


This problem was not present with the older version of linux !!! 


Thanks in advance for your help.

(good to Cc linux-cifs-u79uwXL29TY76Z2rM5mHXA@public.gmane.org though it might not have anything
to do with cifs in this case)

Are you using dhcp? If yes, it looks like a problem due to IPaddress not
being persistent (possibly a bug in dhcpcd).

Are you able to reproduce this problem if you use static IP?  Also, see
if the problem is persisting if you use dhclient instead of dhcpcd.

I seem to have misread. It looks like the client in this case is Windows
box and the Server is Linux. So, if you suspect any issues with Samba,
please report to Samba mailing list. This is not a appropriate list to
discuss non-kernel/non-cifs client issues.

Thanks,
