Package: sane-utils Version: 1.0.15-7 Severity: important
I am using saned on a network. My test use one server (obiwan) with saned daemon and one client (d2r2) with scanimage application. Xinet, services, IP traffic, all is ok.
My network is on 192.168.0.0/16 so the file saned.conf on server is as follow. Please note also that host obiwan use ip aliasing

As you can see, the answer is now correct, because i have a such scanner on obiwan host.
The 2 sequences are the same, and i have made a ethereal on tcp connection. There is only one difference in last tcp transaction from obiwan to client d2r2 before closing the connection, this is of course about the string on scanner identification.
It seems the problem is on server side.
The problem is important, because it is not possible to run saned via xinetd without root access.
Best Regards
