Check that you don't use a firewall or NAT setup that blocks the SANE
data port.

Please try other frontends (xscanimage, scanimage). Does the same

Please try other backends (e.g. the test backend: xsane net:hostname:test).

If you scan using the net backend on the server, does it also hang?
--> e.g.  scanimage -d net:localhost:snapscan:/dev/scanner

Check the logs. On the client side, you can set the environment
variable SANE_DEBUG_NET=255. On the server side, have a lokk at syslog

For more debugging on the server side, disabled saned in (x)inetd.conf
and start it manually like this:

saned -d255
