Hi All,

I am new to Linux, I have one Client-Server application which I have ported
from Windows 2003 to FC5.

But while testing the application if I am plugging out the Ethernet cable
Both Client and Server applications

Are not able to detect that network connectivity is lost, Client application
is able to send data on connected 

socket but Server is not able to get it (here at client side send API is not
returning -1) and after putting the 

cable back they start receiving data again.

Can any body help me out?

Regards,

Ankur.
