Really irritating. Do a "netstat -r" to look at the routing tables... Do this when the ping works and when it doesn't work and see what the difference is...

Hi, I'm running Sun4/370 with SunOS 4.0.3 (which itself is a name server). I ping a host in domain csie.nctu.edu.tw: % ping pdp1 pdp1 is alive Then I ping a host in domain nctu.edu.tw: % ping mozart mozart.nctu.edu.tw is alive Then I ping a host in domain edu.tw: % ping nthu sendto: Network is unreachable Then I kill the routing daemon in.routed and restart it, and % ping nthu nthu.edu.tw is alive After one or two minutes (indeed !), I do it again: % ping nthu sendto: Network is unreachable So I have to restart in.routed each time I wanna connect to domain edu.tw. Really irritating. Any clue ? Kai-Chih Peng kcpeng@ccsun1.csie.nctu.edu.tw
