Works for me in Xenial via systemd. Will update documentation at https://help.ubuntu.com/community/SaneDaemonTutorial with instructions.

However, it now no longer works in Trusty when instead ethernet through a switch or via WiFi router, and doesn't work in Utopic or Vivid. For example, in Windows 8.1 with SaneTwain 1.3.6, it used to work. Now it pops up a window: Error No devices found on backend. However, in the Device drop down it notes: hpaio:/usb/Officejet_5600_series?serial=XXXXXXXXXXXXXX Ubuntu 15.04 client with either xsane or simple-scan doesn't find anything. Running the following from a terminal results in either a crash or no SANE devices found as per https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1442960 : scanimage 192.168.1.15 scanimage: no SANE devices found scanimage 192.168.1.15 *** Error in `scanimage': double free or corruption (!prev): 0x00007f5a939fff10 *** The scanner works fine locally on the server via simple-scan and xsane. Intermediary device networking being the root cause has been ruled out as I connected the server and client via ethernet through a switch, disabled wireless and still reproducible. Confirmed clients and host may ping each other. Tried disabling ipv6 on just and both server and clients, no change. = Trusty Server (upstart) = + 12.04 Client attempting to connect: SANE_DEBUG_NET=128 SANE_DEBUG_DLL=128 scanimage -L net:192.168.1.6 https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1442956/+attachment/4388269/+files/SANE_DEBUG_NET%3D128%20SANE_DEBUG_DLL%3D128%20scanimage%20-L%20hpaio%3Anet%3A192.168.1.6 = Vivid Server (systemd) = scanimage --device net:localhost scanimage: open of device net:localhost failed: Error during device I/O sudo systemctl restart saned.service && sudo systemctl status saned.service -l ● saned.service - Scanner Service Loaded: loaded (/lib/systemd/system/saned.service; static; vendor preset: enabled) Active: inactive (dead) Apr 22 19:40:24 pc systemd[1]: Unit saned.service entered failed state.
