IP only filter?

[Russell Fulton]

HI Carter,
	  Does 'ip' filter out non IP traffic in the client filters? I 
am only interested in IP traffic since nothing else will ever leave or 
enter our network.  It seems to 'do the right thing' but I thought I 
would just check.

I think I have reported this one before and it got 'fixed' but has now 
reverted ('u' dist):  -n and 'delimited fields' prints the protocol as 
numbers instead of words (tcp, icmp, udp...).  This is at variance with 
the normal output where the protocol us unaffected by -n. I don't mind 
much which way we do it so long as it does not keep changing ;-)

There is some logic to having it this way since one could assume that 
'delimited field' output will be going to a program and comparison/ 
sorting of numbers is cheaper than strings and we can always convert 
them back for output if needed.

Russell.
