It's always frustrating trying to figure out when saned/net is not
working.<br class="">
We should look at the server side since it looks like the client is
doing the right things.<br class=""></div></blockquote><div>If I run SANE_DEBUG_NET=10 scanimage -L</div><div>The stdout hangs on the following Line:</div><div><div style="margin: 0px; font-stretch: normal; font-size: 11px; line-height: normal; font-family: Menlo;" class=""><span style="font-variant-ligatures: no-common-ligatures" class="">[15:02:12.126561] [net] connect_dev: net_init (user=[ClientUser], local version=1.0.3)</span></div></div><div>for about 45 secs.</div><div>Does that suggest maybe the problem is `scanimage -L` attempting to communicate the wrong user name?

Firstly, are you sure that the server side is seeing 192.168.0.15 as
the incoming address? If you are accessing it through PAT or NAT
(like often from a VM), then saned is going to see your external
address rather than your internal address.<br class="">
Just thought I would bob that in there, not to insult your
intelligence. ;)<br class=""></div></blockquote><div>Thanks. We're on a LAN with no VMs.</div><br class=""><blockquote type="cite" class=""><div class="">
Secondly, we can try to switch on debugging. When saned is running
as a service it should be outputting diag to the syslog.<br class="">
We should be able to increase the level of that by editing the init
line.<br class="">
On my system (which is Linux Mint 19.3) saned is kicked off by the
init process and is listed in /etc/inetd.conf:<br class="">
<br class="">
sane-port stream tcp nowait saned:saned
/usr/sbin/saned saned<br class="">
<br class="">
Add -d10 to the end of the line and that should increase the
verbosity of the output to the syslog.<br class="">
<br class="">
sane-port stream tcp nowait saned:saned
/usr/sbin/saned saned -d10<br class="">
<br class="">
Try to connect again, then check the bottom of the syslog.<br class=""></div></blockquote><div><br class=""></div><div>Haven't yet tried the "-d10" debugging</div><div>But even before doing that, checking over syslog.
