I'm trying to setup a network service for running saned (running the sane-test backend) on Ubuntu 12.10, running it on a virtualbox.

I followed the directions found here: https://help.ubuntu.com/community/ScanningHowTo and i got to the point where if i use a front-end like xsane, or use the command scanimage -d test i get the desired behaviour. (i get the test image).

But when i try to use the network demon to access the backend (from the localhost) i get Failed to connect.

I used telnet on 127.0.0.1 6566 and i got the following error: saned: symbol lookup error: saned: undefined symbol: sanei_w_init

I'm a linux newbie, so i could be making some stupid mistake. Any ideas on how to fix this? Thanks

[update]After posting this question i logged out, logged back in and it worked. After a few days i tried again and it gave the same error as before. Any help?
