Hi, building a box with no other interface than tcp/ip. now in case something goes wrong when changing the /etc/network/interfaces via ftp and when rebooting the system cannot bring the interface up I would like to be able to detect it and replace the interfaces file with a default one stored on the system. any clues appreciated

Well, the easiest way would be to add:

Code:

*/5 * * * * /root/go.sh

to your crontab, which will run every 5 minutes. If you aren't able to log in and disable it, it will run, copy over the new interfaces file and reboot.

Code:

[go.sh] script file should contain

/bin/cp /etc/network/interfaces.backup /etc/network/interfaces; reboot;
