[SOLVED] I fail to use my scanner over the network

markush · 10-11-2009, 03:46 PM

Hello together,

I want to use my scanner over the network. I have three Linux-PCs in a network, all running Gentoo. On one of the PCs there is a HP-PSC1410 Printer/Scanner installed.
Printing with Cups via network and from the local machine works well. Also scanning from the local-machine (the scannerserver) using xsane works well.
Now I want to use the scanner from the other machines. With google I found some tutorials about scanning over the network , but the tutorials are somewhat dated.
I've installed xsane, sane-backends and hplip on all machines. On the scannerserver I have installed xinetd and configured it to start saned if a request comes via port 6566/TCP. I created a file etc/xinet.d/saned:

Code:

# /etc/xinetd.d/saned
service sane-port
{
  port        = 6566
  socket_type = stream
  wait        = no
  user        = daemon
  group       = daemon
  server      = /usr/sbin/saned
}

This seems to work. nmap -sV gentoo gives the following output:

Code:

# nmap -sV gentoo
PORT     STATE SERVICE  VERSION
631/tcp  open  ipp      CUPS 1.3.10
6566/tcp open  unknown?

which means that the port for scanning-requests is open. On the clients there is /etc/sane.d/saned.conf configured for scanning over the network. When I run scanimage -L on one of the clients I get

Code:

# scanimage -L
No scanners were identified ......

At the same time, using tcpdump on the scannerserver I can see the request comming to the scannerserver and syslog-ng logs

Code:

# tail -f /var/log/messages
Oct 11 22:08:27 Gentoo saned[4427]: saned from sane-backends 1.0.19

At this point I need a little help. Has anyone an idea? Thanks in advance

Hello paulsm4,

thank you very much

.

I've edited the /etc/udev/rules.d/70-hpmud.rules file and changed some permissions. After rebooting (since I don't yet know how to restart udev on my Gentoo-system in a safe manner) it worked. scanimage -L shows the device and I'm able to start xsane from one of the clients and use the scanner.
