Hi there!
I got a Lexmark printer/scanner combo which used to work fine on my arch install. However, its mobo died, so now I'm back at another install which refuses to scan. Scanning is done through the browser via a java applet residing on the printer's webserver. The applet does start (so it's not a java issue), but refuses to receive data from the scanner. Within the printer's web interface, it reads
If using Windows XP, the Windows XP personal firewall must be disabled before using Scan to PC profiles.
, so I'm assuming it might be a firewall issue. Lexmark's website provides the following advice:
The following two command lines will open the port 5353 for incoming and outgoing connections:
iptables -I INPUT -p udp -m udp --sport 5353 -j ACCEPT iptables -I OUTPUT -p udp -m udp --dport 5353 -j ACCEPTNOTE: These steps will work on most distributions configured with IPTABLES. There is no common command to make these rules persistent.
As I don't know anything about IP tables, I've simply copied these commands (as root, obviously). Still, I can't scan.
So, my questions are:
1. Has anybody else ever come across an issue like this?
2. I don't even know for sure, whether this is a firewall issue - What iptabled magic would I need to temporarily disable the firewall to check?
3. I tried checking my rules by "iptables -L". How can I tell "iptables -L" to specify the ports it is working on (as I did in the commands copied from lexmark's website)?
Best wishes,
Rufus
