It can also be done by using any of these techniques:
- Use the "ipparam <string>" option. This shows up as the sixth
parameter ($6) inside the script. You can give it an aribitrary
string to identify the connection in some way that's locally
meaningful.
- Use the "linkname <name>" option. This must be a 'simple' string
that can be used as an ordinary file name (as in "foo" but not
"a/b"). It shows up inside the script as $LINKNAME, and alters
the name of the /var/run PID file.
- Use the "unit <number>" option to set the "spppX" unit number.
The interface name is available to the script as $1.
- Use the tty to distinguish callers, via $2.
- Use the $PEERNAME environment variable. This will have the
authenticated peer name, if any.
Which one you use depends on your local circumstances, but I think
ipparam is probably the most flexible answer.
