[sane-devel] No scanners detected on LTSP fat client when net.conf uses hostname

I remember you from the Alt Linux and/or ALTSP lists. It's a small world.
I noted in the original post that a fat client can ping the server
hostname successfully, and also that a standalone on the network with a
net.conf configured with the server hostname successfully scans with the
I thought those were very solid indicators that this is not a name
resolution issue, but I do get some indicators of that very issue from
host and resolv.conf output:
_server_ _fat client_ _standalone_
$ host <ltsp-servername> 127.0.1.1 127.0.1.1
$ /etc/resolv.conf 127.0.0.1
So indeed, the fat client and standalone are handling those
differently. I'll look into it further. Thanks!
