#IPV6 OPENDNS UPDATER INSTALL#
If you get the following message “Unit: rvice could not be found” then skip ahead and install resolvconf. Open up a Terminal window and enter the following: sudo systemctl status rvice I will list here the most popular DNS providers:ĭepending on which version of Ubuntu/Debian you’re using, resolvconf may or may not be installed, so let’s check before we continue. I recommend Google DNS which is what I use and have never had an issue. Video: Set permanent DNS nameservers on Ubuntu/Debian with nfīefore changing DNS servers, you’ll need to find a third-party DNS provider, there are plenty of good (and free) services available.We’ll be editing the head file so that each boot-up, nf gets written with our custom DNS servers at the top. Instead, we edit one of the two files used to create the nf file, those being the head and base files. This guide will use nf, see my other guide for setting custom DNS servers using Network Manager or Netplan.įYI: The nf file is overwritten on each boot so we can’t edit this file directly. There are several ways to do this including Network Manager GUI that’s included in many Linux distros like Debian, Ubuntu and derivatives, Netplan which is now included as standard in Ubuntu 20.04 or using nf (not directly, but via the head file). I've got the permissions set to 755 on that script, so I'm a little confused why it wouldn't work, but at least it works as a regular cron job.Setting custom DNS servers on Linux can increase performance, security and even thwart some websites using Geo-blocking via DNS. (neither ddclient is updated nor is /tmp/ddclient-bg-updated created) I tried to setup a cron.hourly folder and putġ1 * * * * root run-parts /etc/cron.hourly I had to reboot to get it to rebuild /etc/crontab. I waited a day first and it didn't rebuild. Ps. dont forget to delete the "backup", after you edit crontab.logging there will be a backup made of crontab.logging~ which you should remove since otherwise you will get the events run 2x as both files are inserted into the crafted crontab file.Ĭreate a new file in /etc called crontab.custom or similar (I used crontab.myinitials)Ġ5 * * * * root /usr/sbin/ddclient -daemon 0 -file /etc/ddclient/nf This will cause it to be built into the crontab and run daily at 5:30 etc. you can google crontab syntax for more details on this if you like. Hope that clears up a way to add your own timed things via the cli.just watch after an up2date that your lines are still there, if not you will have to re-add them. Also, you could just create crontab.custom which wouldn't be overwritten, but i havent tried that lately to see if we parse with crontab.* or an actual list of specified files. The crontab is actually "built" at certain intervals via the various crontab.* files. Such as these files can often be replaced/built via up2dates, so if you have something custom you want to run as part of a certain process, simply add it like:ģ0 5 0 0 0 root /home/login/yourscript (eg) I'm trying cron.hourly now, but I'm not certain Astaro actually runs anything out of there. If not, /etc/crontab could be adjusted.ĭisclaimer: if you have an Astaro support contract, messing with the command line may void your support. I set up the config file last week, and #2 did work, but I just noticed today that #3 didn't work after a reboot. usr/sbin/ddclient -daemon 0 -file /etc/ddclient/nf usr/sbin/ddclient -file /etc/ddclient/nfģ. try to put it in the Astaro startup. if you do, remove the '-daemon 0' option from the command line. I tried putting it at the end of /etc/init.d/beeps but that didn't work.Ĥ. put a script in /etc/cron.hourly which contains:
