Hi, I think I misconfigured something, but I can't figure out what.
My "server" is running saned. There is an old LaserJet 2840 connected via network. "Local" scanning (over the hpaio backend (included in hplip) using the ethernet connection) works fine. Even scanning using the net backend works perfectly, as long as I specify it on the command line. The only thing that is not working is detecting the scanner using scanimage -L. On the other Linux boxes this is not a problem, as I can just tell scanimage or xsane which device they should use. But some of the Windows software I tested so far needs to detect the scanner by itself. (Scanning from Windows is the reason I'm trying to get network scanning up and running in the first place as there are no drivers available for the scanner part of this printer for any Windowses beyond XP. Linux support on the other hand is still pretty good. And, yes, it is a strange setup, setting up a networked scanner to be used with saned over the network, effectively sending twice the data over the net, but that's what I'm trying to do...) ;-) I'd settle for using xsane on the windows installations, too. It actually works with an very old xsane binary I found on archive.org for testing purposes; I'd have to build something more recent with cygwin or something. ...but I guess the other users would hang me if they can't scan directly from their photoshop or paint or whatever... ;-) Anyways: Here's my configuration (on the server, 192.168.1.1): /etc/sane.d # cat dll.conf hpaio net /etc/sane.d # cat saned.conf # data_portrange = 10000 - 10100 192.168.1.1/24 /etc/sane.d # cat net.conf 192.168.1.1 localhost (On the clients I removed the localhost entry in net.conf.) /etc/sane.d # SANE_DEBUG_HPAIO=128 SANE_DEBUG_NET=128 saned -d128 [saned] main: starting debug mode (level 128) [saned] read_config: searching for config file [saned] read_config: done reading config [saned] saned (IPv4 only) from sane-backends 1.0.25 starting up [saned] do_bindings: trying to get port for service "sane-port" (getservbyname) [saned] do_bindings: port is 6566 [saned] do_bindings: socket () [saned] do_bindings: setsockopt () [saned] do_bindings: bind () [saned] do_bindings: listen () [saned] run_standalone: waiting for control connection [saned] handle_connection: processing client connection [saned] check_host: access by remote host: 192.168.1.3 [saned] check_host: remote host is not IN_LOOPBACK [saned] check_host: local hostname: sauserver [saned] check_host: local hostname (from DNS): sauserver.sauhaufen [saned] check_host: local host address (from DNS): 192.168.1.1 [saned] check_host: remote host doesn't have same addr as local [saned] check_host: opening config file: /etc/hosts.equiv [saned] check_host: opening config file: saned.conf [saned] check_host: config file line: `# data_portrange = 10000 - 10100' [saned] check_host: config file line: `192.168.1.1/24' [saned] check_host: subnet with base IP = 192.168.1.1, CIDR netmask = 24 [saned] check_host: access granted from IP address 192.168.1.3 (in subnet 192.168.1.1/24) [saned] init: access granted [saned] init: access granted to [email protected] [saned] process_request: waiting for request [saned] process_request: got request 1 [sanei_debug] Setting debug level of hpaio to 128.
