Just curious to know, what do the ifup and ifdown commands do? Can they be used?
ifdown brings down the interface temporarily. The interface would still go up on next reboot or restart of the network services. ifup does the opposite..brings up an interface if its not already up at boot time.
In a debian distro they also execute all scripts in the /etc/network/if-up.d/ and /etc/network/if-down.d/ directories. so you could add scripts in there to automatically do things on ifup / down. Ther is also if-post-down.d / if-pre-up.d directories which do the same after the inerface is up / down. Similarly for ppp.
