Rajesh Kulkarni A lot has changed with the 4-6 release. Don't fool around with /etc/network/interfaces or /etc/resolv.conf.
As debian user in the home directory. cd ~/ mkdir cronjobs copy the attached file into cronjobs cd cronjobs Read the top of the file postboot.sh The following must be done as sudo because the user level will not have permission. . sudo crontab -e Make entry as explained in postboot.sh This entry will execute at boot time and sleep 20 seconds to allow the system to be up. This may seem complicated. The reason for this setup is you can later if needed make other cronjobs as you or as sudo. Remember full pathnames and any executed commands requiring sudo access will need to be added as sudo crontab -e. If you want a user level cronjob just do crontab -e When this script runs at boot time it will create a file called log. You can cat log to see the results of the current boot. postboot.sh also updates the system date/time. Please nano or vi postboot.sh and verify your Country / Time Zone. So, backup original cp /etc/network/interfaces ~/. Then clean up using sudo nano /etc/network/interfaces The only two active entries should be: auto lo iface lo inet loopback Reboot sudo reboot then cat log in cronjobs Let me know how it works out.
