| Ugly hack to run chrome in a memory-limited cgroup so it does not kill your workstation | |
| when it tries to consume all available memory. | |
| Put this in /usr/local/bin/cchrome, add that to whatever menu system you are using. | |
| You can verify it worked by running: | |
| grep memory `ps ax | grep chrome | grep -v grep | awk '{printf "/proc/%s/cgroup\n", $1}'` | |
| This has only been tested on kubuntu desktop. Obviously, if you have not enabled | |
| passwordless-sudo for yourself, create and chmod the cgroup directory from some |

My ISP (Time Warner Cable) hands out IPv6 addresses with DHCPv6;
it will delegate a /56 if asked. So long as I keep refreshing the lease,
it won't renumber me. I have my cable modem set to bridge, and do all the
firewalling, NATing, etc., on a Debian box.
In what follows, eth0 is the internal interface.
The dhclient that ships with debian/ubuntu does not support asking for a prefix delegation, so I had to build one from sources.
