나는 확실히에 대한 아니에요 tun0,하지만 난에 스크립트를 생각 /etc/network/if-up.d/하고 /etc/network/if-down.d/인터페이스가 각각 상승 또는 아래로 때 호출된다.
스크립트 내에서 변수의 내용에 관심있는 인터페이스를 결정할 수 있습니다 IFACE.
확실하게 /etc/network/if-up.d/내용이 있는 간단한 스크립트를 추가하십시오.
#!/bin/sh
# filename: tun-up
if [ "$IFACE" = tun0 ]; then
echo "tun0 up" >> /var/log/tun-up.log
fi
그것을 실행 가능하게 만드십시오
sudo chmod +x /etc/network/if-up.d/tun-up
그런 다음 up 이벤트가 기록되는지 확인하십시오. /var/log/tun-up.log
gksudo gedit /etc/network/interfaces
더하다:
auto tun0
iface tun0 inet manual
up COMMAND
COMMAND는 ip route add something...실행 권한 ( chmod +x)이 있는 스크립트 경로와 같은 명령 이거나 결국에 저장 될 수 /etc/network/if-up.d/있습니다.
대신에 up당신이 사용할 수 있습니다 post-up, down, post-down.

The following "command" options are available for every family and method. Each of these options can be given multiple times in a single stanza, in which case the commands are executed in the order in which they appear in the stanza. (You can ensure a command never fails by suffixing them with "|| true".) pre-up command Run command before bringing the interface up. If this command fails then ifup aborts, refraining from marking the interface as configured, prints an error message, and exits with status 0. This behavior may change in the future. up command post-up command Run command after bringing the interface up. If this command fails then ifup aborts, refraining from marking the interface as configured (even though it has really been configured), prints an error message, and exits with status 0. This behavior may change in the future. down command pre-down command Run command before taking the interface down. If this command fails then ifdown aborts, marks the interface as deconfigured (even though it has not really been deconfigured), and exits with status 0. This behavior may change in the future. post-down command Run command after taking the interface down. If this command fails then ifdown aborts, marks the interface as deconfigured, and exits with status 0. This behavior may change in the future. There exists for each of the above mentioned options a directory /etc/network/if-<option>.d/ the scripts in which are run (with no arguments) using run-parts(8) after the option itself has been processed. Please note that as post-up and pre-down are aliases, no files in the corresponding directories are processed. Please use if- up.d and if-down.d directories instead. All of these commands have access to the following environment variables. IFACE physical name of the interface being processed LOGICAL logical name of the interface being processed ADDRFAM address family of the interface METHOD method of the interface (e.g., static) MODE start if run from ifup, stop if run from ifdown PHASE as per MODE, but with finer granularity, distinguishing the pre- up, post-up, pre-down and post-down phases. VERBOSITY indicates whether --verbose was used; set to 1 if so, 0 if not. PATH the command search path: /usr/local/sbin:/usr/local/bin:��� /usr/sbin:/usr/bin:/sbin:/bin Additionally, all options given in an interface definition stanza are exported to the environment in upper case with "IF_" prepended and with hyphens converted to underscores and non-alphanumeric characters discarded. When ifupdown is being called with the --all option, before doing anything to interfaces, if calls all the hook scripts (pre-up or down) with IFACE set to "--all", LOGICAL set to the current value of --allow parameter (or "auto" if it's not set), ADDRFAM="meta" and METHOD="none". After all the interfaces have been brought up or taken down, the appropriate scripts (up or post-down) are executed.
나는 systemd후에 스크립트를 실행하는 데 사용 했습니다 network-online.target. 내 스크립트 <path>/script.sh.
1.) sudo systemctl edit --force --full my-script.service:

2.) sudo systemctl enable my-script.service
삼.) sudo systemctl start my-script.service
