The machines involved are both running "saned -a". It works well until I turn on iptables on the machine with the scanner. If I enable firewalling with port 6566 open the scanner initializes but never proceeds beyond that point. I tried these: -A INPUT -p tcp -m tcp --dport 6566 -m conntrack --ctstate NEW -m helper --helper "sane" -j ACCEPT -A INPUT -p udp -m udp --dport 6566 -m conntrack --ctstate NEW -m helper --helper "sane" -j ACCEPT but that results in "no scanners found". Using CUPS as an example I did this on both sides and didn't have any luck that way either. Sorry if I can't better describe this. I've never used a scanner over the net before and netfilter's helpers are new to me. Google finds many references to iptables and sane, but only in the context of sanity, which I am quickly losing ;D Any helpers? TIA, Mike Wright
