| H A D | routing | diff 47752 Sat Jun 05 03:45:57 MDT 1999 phk Add handle to control global TCP keepalives and turn them on as default. Despite their name it doesn't keep TCP sessions alive, it kills them if the other end has gone AWOL. This happens a lot with clients which use NAT, dynamic IP assignment or which has a 2^32 * 10^-3 seconds upper bound on their uptime. There is no detectable increase in network trafic because of this: two minimal TCP packets every two hours for a live TCP connection. Many servers already enable keepalives themselves. The host requirements RFC is 10 years old, and doesn't know about the loosing clients of todays InterNet. |
