Hi,

I have built  FreeTDS with unixODBC 1.8.12 on redhat 6.2, and I am
trying to get a connection to a sybase 11.9.2 database via the
interfaces file (I haven't set up one of those new configs, as the
perl script to do it appears to be missing from the source tarball).

With uniODBC isql the connection just hangs. Strace shows it is stuck
in some kind of host name lookup:

oll([{fd=4, events=POLLIN}], 1, 5000)  = 0
ioctl(4, SIOCGIFCONF, 0xbfff8558)       = 0
ioctl(4, SIOCGIFFLAGS, 0xbfff8568)      = 0
sendto(4, "y+\216\200\0\0\0\0\0\0\0\2\0\1\206\244\0\0\0\2\0\0\0\3"..., 
88, 0, {sin_family=AF_INET, sin_port=htons(775),
sin_addr=inet_addr("194.193.54.4")}}, 16) = 88
poll(

194.193.54.4 is our internal nameserver. 

With libodbc++ isql++ the connection gets further, but there is a seg
fault:

$ gdb isql++
(gdb) r ANVILDEVTDS nightlyuser xxxxxxxx

I would be interested in others experience in similar
configurations. I don't think theirs anything special about my setup.

Cheers,
Alex.
