What is Port 631 used for ?

[techism]

Hello everyone,

I ran a firewall test on PCBSD and found that 631 /ipp port
[IPP Internet Printing Protocol] was open after scanning my computer.
Does this have something to do with Cups? Does it have to remain open?

Also - after reading a few suggestions from posters here - I disabled SSH. I also disabled Samba. To the best of my knowledge I don't need both of these. Am I correct?

Just trying to lock down and secure a little better.

I am strictly using this box for internet - reading e-mail - and Photography.

Thanks in advance.

Cups does use 631. Open your browesr and address localhost:631 and if your cups is setup correctly it should give you a cups administration page. If you plan on printing using cups, keep it open.

If you are using PC-BSD 1.2 then you can leave ssh enabled if you want to ssh in for a shell or remote desktop. The denyhosts script keeps intruders out in pretty good fashion.

Thanks. I thought so but wasn't sure.
