[Vserver] Re: future vserver on ubuntu
Gerald at uni-klu was kind enough to reply to a query I sent him. He will not soon be building a vserver kernel for edgy because of lack of time. So I think I'll stick to dapper for a while yet. Regarding vserver and feisty, it's very likely that the patch is not in the distribution because it's no longer in sid. And it makes sense not to include it in sid since debian is building kernels with built-in vserver. For all architectures too! They even have kernels with xen+vserver!!!

shows that things work as expected as I move the nic around the USB tree.

True - but naming by hardware address is not the only choice.

You can specify the driver module to be used (untested here).

I do not have a clue to that answer.
The files on kernel.org show that 2.6.16 and 2.6.18 are being maintained
more recently than 2.6.17 - I do not know why that is.

Find where your host distribution keeps its udev rules,
rename your nics using their hardware (mac) address, like:

Thanks for that advice, but this vserver is an internal development platform for a real server, which (of course) does have all those /dev entries . So security in this guest is not an issue. But it probably is not a good idea to have all that static dev entries that are for 2.4 kernels running with a 2.6 vserver enabled kernel, idn't it. So I did remove all that crap, left only crw--- 1 root tty 5, 1 2006-11-19 15:14 console crw-rw-rw- 1 root root 1, 7 2005-07-12 14:14 full prw--- 1 root root0 2006-11-19 15:14 initctl crw-rw-rw- 1 root root 1, 3 2005-07-12 14:14 null crw-rw-rw- 1 root tty 5, 2 2006-11-19 15:12 ptmx drwxr-xr-x 2 root root 4096 2006-11-15 18:34 pts crw-rw-rw- 1 root root 1, 8 2005-07-12 14:14 random crw-rw-rw- 1 root tty 5, 0 2006-11-19 15:04 tty -rw-r--r-- 1 root root 582 2006-11-19 15:13 tty10 cr--r--r-- 1 root root 1, 9 2006-11-15 18:34 urandom crw-rw-rw- 1 root root 1, 5 2005-07-12 14:14 zero But now I get an: [EMAIL PROTECTED]:~# vserver dakar enter vlogin: ioctl(): Not a typewriter [EMAIL PROTECTED]:~# and login via ssh is now broken too :-( Nov 19 15:08:56 dakar sshd[1912]: error: openpty: No such file or directory Nov 19 15:08:56 dakar sshd[1912]: error: session_pty_req: session 0 alloc failed Should I check with an non grsec vserver-kernel?
