Hi All, I have a small question on SO_KEEPALIVE socket option. I have a client and server running on two different machines (communicating over tokenring). If I power down one of them the other partner does not come to know about it. I have the socket option SO_KEEPALIVE set on both sides. I found some documentation which says that, SO_KEEPALIVE serves the purpose only if it is enabled at the interface level. (ifconfig eth0 keepalive 30). Is it true ? The Olympice tokenring driver does not seem to support keepalive option. Could you help me to understand it better ? Thanks and Regards, --Thomas http://mobile.yahoo.com.au - Yahoo!
