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 ?
