| # This script is run by the pppd _after_ the link is brought down. |
| # It uses run-parts to run scripts in /etc/ppp/ip-down.d, so to delete |
| # routes, unset IP addresses etc. you should create script(s) there. |
| # |
| # Be aware that other packages may include /etc/ppp/ip-down.d scripts (named |
| # after that package), so choose local script names with that in mind. |
| # |
| # This script is called with the following arguments: |
| # Arg Name Example |
| # $1 Interface name ppp0 |
| # $2 The tty ttyS1 |
| # $3 The link speed 38400 |
| # $4 Local IP number 12.34.56.78 |
| # $5 Peer IP number 12.34.56.99 |
| # $6 Optional ``ipparam'' value foo |
| |
| # The environment is cleared before executing this script |
| # so the path must be reset |
| PATH=/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin |
| export PATH |
| # These variables are for the use of the scripts run by run-parts |
