I've got the same problem with ircd 2.9.2
( It's quite a bit different for me.. As in a config test, I don't
have a DNS.. )
If I setup a DNS and use gethostbyname, that's okay..
If I just have NIS entry for hosts, ircd can't resolv its hostname
(and idem for all clients comming from the local network)
Here, at work, with SunOS 4.1.3, no DNS , only complete NIS maps
entry... ircd can't resolv its hostname, neither clients hostname
(on the local network)
Gethostbyname return an errno > 0 in this configuration, h_errno is
set to 0 and gethostbyname() return the correct info from NIS
database .. Very often, boggus code check 'errno'.. and not
'h_errno' .. The correct test would be :
if ( (hostentry=gethostbyname("foobar")) == NULL)
{
/* .. test h_errno here.. */
}
errno=0; /* delete this boggus return code */
h_errno is define in /usr/include/netdb.h
error code too..
fifi...
