matchportcon?

matchportcon?

[Dave Quigley]

Do we have an equivalent of matchpathcon for ports? Where we can specify 
a protocol and port and see what the policy thinks it labeled?

Closest approximation I can think of would be to use
checkpolicy -Mdb /path/to/policy
and then choose 9, input the protocol and port number, choose 1, and
input the SID that was displayed.

It would be very nice to have a more user-friendly (and scriptable) 
interface to the checkpolicy -d (debug) functionality.

So over on fedora-selinux dominic grift suggested I use sepolicy 
network to check it out. The only issue with its usage is that it 
doesn't tell you what it actually is. Instead it gives you all rules 
that will match and you have to realize the most specific one wins. It 
is however sufficient for my talk so I'll probably use it.

sepolicy network -p 80

sepolicy is reading the info from the running kernel.
