I am trying to setup a dynamic slip arrangement using FreeBSD as a slip 
server. I suppose I will tie each port to a specific IP address, but am 
having trouble with the actual implementation.

I was trying something like this

slip-start script contains 

/usr/sbin/sliplogin `tty | tail -b 6` 

and has permissions 2555 and is in the SLIP group

sliplogin has permissions 4550 and is in the slip group

And no person is in the slip group. So ideally, everyone would have to 
run slip-start, it gives them the slip group, they can then run sliplogin 
which set's their UID to root so that they can sliplogin with their TTY 
as their login name. However, this all falls apart because [for some 
reason] the user isn't able to run sliplogin. Root can run it just find, 
and if a user is in the slip group, they can run it fine, but the 
setgroup ID thing doesn't seem to be doing much for it.

Any ideas on a workaround?
