Linux/HylaFAX/NIS Workaround

[Mark Vitek <mvitek@emccta.com>]

Under Linux (RedHat 4.1), running NIS, the
hostname/address resolution in InetTransport.c++
fails to properly resolve a given hostname.
It appears to be a bug somewhere in the Linux
NIS code.  However, here is the diffs to
implement a workaround.
Can not reach server at host "fax", port 4559.

Subject: Configuration of hylafax client only

We are running the fax deamon on a SGI Indigo 6.2, but also want to send 
faxes from our sun workstations. As far as I understand you don't need the 
tiff library or ghostscript for the hylafax clients.

If I'm correct, does anyone has a configuration file for a clients only 
configuration, without tiff library & ghostscript requirements, or can 
anyone tell me what to change?

Thanks,
