Had a look at cups-browsed.conf, and that has the BrowseAllow/Deny/Order options. So I set Order to 'Allow,Deny' and set Allow to the IP of our printhost. However, if I then start cups-browsed, and check open ports, it still says cups-brow 120068 root 7u IPv4 156935 0t0 UDP *:ipp
So it's not really clear to me if that method is sufficient. The article doesn't help there...
Any opinions?
Isn't that lsof? lsof only shows (lsof -i :ipp) if port ipp (631) is open not what to do with it, right?
Yes, that's what I was unsure about...
I'd nmap my computer from another one:
nmap -sU -T5 -p 631 <your_ip>
Ah thanks. I don't speak nmap, so I didn't think of that. It tells me PORT STATE SERVICE 631/udp open|filtered ipp That would strengthen the idea that above method is sufficient to block unwanted access to the port without needing to shut down the service...
