I'm a new Linux user as well, so this may be obvious to everyone else but I got caught out until I realised that Ubuntu overwrites changes made to sysctl.conf when you reboot unless you use the correct command to edit the file.
The command is: sudo gedit /etc/sysctl.conf If you just edit the file without 'sudo' then the changes will be overwritten on reboot. Hope this helps! -- Network problem since kernel-2.6.17 https://bugs.launchpad.net/bugs/59331 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
