## On my host, pppd invokes this script with args:
|
||
|
|
## /etc/ppp/ip-up.local ppp0 /dev/pts/1 115200 192.168.2.1 192.168.2.3
|
||
|
|
##
|
||
|
|
## From the manual page for my pppd, these aguments are:
|
||
|
|
## scriptname interface-name tty-device speed local-IP-address remote-IP-address ipparam
|
||
|
|
##
|
||
|
|
## Some people have reported that their pppd returns their
|
||
|
|
## local-IP-address as $3. If that's also the case for you,
|
||
|
|
## you may need to change the $4 below to $3. This may not
|
||
|
|
## be necessary if you pppd also passes the local-ip-address
|
||
|
|
## in the environment as either PPP_LOCAL or IPLOCAL.
