Hi,

I'd like to create a log file which can allow me to know when my provider change my IP. I just need to know the date and the hour of the disconnection. Does anyone know?

Thanks

The dhcp information your looking for is located at /etc/dhcpc/. I'm not sure if these files are only modified on reboot or by the dhcpc daemon, but I think they're modified by the daemon. You could make a copy of the current files and put them into a log, say at /var/log/dhcpc. You could have a log file for every interface using dhcp. So one might look like /var/log/dhcpc/dhcpcd-eth0.log. It would contain the concatenation of all changed dhcpcd-eth0.info files. Then write a small cron job that gets executed on an hourly basis it would just need to check the timestamp on the dhcpcd-eth0.info file and compare it with the dhcpcd-eth0.log file, if the info file is newer, then concatenate the new info file to the log. I'll see if I can come up with something and post it here if I do.
