A strange thing...
On our Unix system (TP-IX/68K 1.23 which is based on AT&T V.3.2) the
function open-network-stream hangs in the function gethostbyname().
sdb indicates that the hang is occurring in res_send.c (internal to
gethostbyname) after it has done a select() which indicates there is a
packet of data returned by named; it then does a recv() which hangs.
Further investigation shows that killing the name daemon named makes
it work OK. A vanilla gethostbyname("valid-host") inserted just
before the proper gethostbyname() also hangs, so there's nothing wrong
with the argument. A dummy program which just does a
gethostbyname("same-host") works OK, as do all the network utilities
which are built with the same library.
Hitting ^G during the hang causes gethostbyname() to return *with the
right answer*, but then Emacs aborts the function (of course).
Any ideas?
Thanks!
Tim
