Network scanning with Linux and Sane

Hooray, today I setup a network scanner on my home network.

The server is running Fedora 10, has the scanner attached, and the saned daemon running. Both Linux and Mac clients access the scanner using the sane/net backend. In the case of Mac OS X it’s really twain-to-sane/net-to-server. Can Vista talk to a sane network scanner: FIXME.

The big gotcha is the iptables firewall on the server. Apart from the sane-port it proceeds to open a few other ports during data transmission. Therefore you must load the nf_conntrack_sane.ko module. In the case of Fedora 10, it’s configured in /etc/sysconfig/iptables-config. I hope this helps others who run into the firewall/saned problem.
