Network issues - resolvconf problem












0














Internet access is available for a brief second when the browser is initiated, but after a split second, internet connection is unavailable.



Searching a bit in the forum, I found out that



dpkg-reconfigure resolvconf and service network-manager restart



resolved the problem temporaly, needed to be done after every boot.



This happended after running xflock4 with the shortcut CTRL+ALT+L. The screen went black for a minute, then became red.
Without response, I powered-off the machine manually.
Is there a permanent fix?

          1) You shouldn't manually update your resolv.conf, because all changes will be overwritten by data that your local DHCP server provides. If you want it to be static, run sudo dpkg-reconfigure resolvconf and answer "no" to dynamic updates. If you want to add new entries there, edit /etc/resolvconf/resolv.conf.d/base and run sudo resolvconf -u, it will append your entries and DHCP server's entries.



          2) Try to edit your /etc/network/interfaces and add your entries there, like



          auto eth0
          iface eth0 inet dhcp
          dns-search google.com
          dns-nameservers dnsserverip
          and then restart /etc/init.d/networking restart or sudo ifdown -a and sudo ifup -a



          3) Your system uses udhcp which is a very small DHCP client program. The udhcp client negotiates a lease with the DHCP server and notifies a set of scripts when a leases is obtained or lost. You can read about it's usage here or just edit this script (as you did).

          • This was a bigger hassle then I expected. I ended up reinstalling the system in the end. Thank you for your kind response, Mayur, but I couldn't fix it, sadly.
