Alright then mine is a different problem.

[Bug 571933] Re: dhclient3 hangs on shutdown
It seems that the DHCP server does not reply to DHCPRELEASE so dhclient waits until timeout. My DSL modem does the same. My workaround is to remove /etc/rc0.d/S35networking and /etc/rc6.d/S35networking, but I would like to know if there is a way to configure dhclient to ignore release requests, without messing with init scripts. Also on reboots the client should NOT release the address according to the protocol, so maybe this is ALSO a bug in the init scripts. -- dhclient3 hangs on shutdown https://bugs.launchpad.net/bugs/571933 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dhcp3 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Thank you for opening this bug and helping make Ubuntu better. On Lucid network startup/shutdown should be done via upstart (/etc/init/), not via /etc/init.d.

I think my previous two comments really have nothing to do with the actual problem. Me just grasping at straws trying to find some kind of information. The following patch is a hack and not anywhere close to a solution but does make the /etc/init.d/networking script complete during shutdown. ** Patch added: networking.patch http://launchpadlibrarian.net/46522420/networking.patch -- dhclient3 hangs on shutdown https://bugs.launchpad.net/bugs/571933 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dhcp3 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
