Scan from network multifunciton device

Hi;
I have installed a new network multifunctional device Samsung CLX-3185FN using the drivers provided by the manufacturer (Samsung Unified Driver). The printing over the network works fine, I can administer the device using browser. The only problem I have is using scanner over the network. It works fine if I disable firewall, but is blocked with firewall enabled. I can not figure out which ports or port-range I must enable for this scanner. Do you have any information on this one or how can I found out the necessary ports to open?

Thank you;
Luka

well... One way is to start a scan, and look (netstat -an) and see what
ports are in use.

Do it again while not scanning and see the differences.

Won't help a lot if the port can vary (as in, the application tells
the scanner what port to use).

I usually scan using Simple Scan 2.32 using Fedora 14. The ports are do in fact vary. how to get around this? I can not have firewall opened just to scan a couple of documents every couple of hours. Who decide which ports are used for comunication: scaner or my software (Simple Scan)? how to set firewall so it will open the necessary ports?

Regards; Luka

Re: Scan from network multifunciton device

There should be some documentation with the scanner software - it has to
be the software that tells the scanner which port to use for return connections
(like a FTP data connection). The documentation should say
what range of ports (port range) the client will use for listening. The
only other way is to look at the source code... Most of the client
applications I've used have a way to specify an allowed range.
