Re: [Vserver] /dev/null: Permission denied
Hi, Whenever I start the vserver, init scripts accessing /dev/null (or any subsequent commands) returns Permission denied. Re-creating /dev/null outside the vserver does not help. ls -l shows this is a proper device file: Ensure the partition were your vserver is located is not mounted with the NODEV option. The mount command in the host should show it if that is the problem. I think a default debian install has all but the root partition mounted with NODEV..

Re: [Vserver] SSH login inside vserver not working
Hi, Thanks for the tip, I was not aware of it. I did finally fix this issue. The problem was missing /dev/pts support in the kernel. What's really strange is that ssh was working on the host system but not inside the vservers, but after enabling /dev/pts, everything worked.. Anyhow, thanks everyone for the help! -- Cedric On Mon, 2004-03-15 at 15:10, Sam Vilain wrote: Use sshd -t -p NNN (where NNN is a port number) inside the vserver. then ssh -v -p NNN yourhost All will be revealed. If you don't even see the daemon process do anything, then you have a more basic firewalling / routing / etc issue. `tcpdump' and `netstat -plunt' are also highly recommended. Sam.

[Vserver] Which devices are required inside the vserver?
Hi, I am sorry for posting about such a basic issue. I do not use the vserver script to build the vservers, and I haven't found a clear answer to this question on the Wiki... So, what are the minimum devices required inside a vserver? This must be documented somewhere so if someone can point me in the right direction it would be very welcome. Thank you! -- Cdric

[Vserver] SSH login inside vserver not working
Hi, After upgrading from an old-world 2.4.20ctx-17 to 2.4.25-vs1.26, I can no longer login to an SSH server running inside a vserver. Beside the change to the host server, nothing has changed with the virtual server. When login in with openssh's ssh client, it just hangs there indifinately after asking for the password. When login with putty, I get the message Server refused to allocate pty. I tried to change the shell of the user of the vserver from bash to sash (static shell), and I was able to login into a somehow broken shell. Here's the output of me logging in and then typing the 'w' command: bash-2.05b$ ssh [EMAIL PROTECTED] [EMAIL PROTECTED]'s password: $ readline: warning: rl_prep_terminal: cannot get terminal settings 11:22:53 up 3 days, 20:43, 0 users, load average: 0.00, 0.00, 0.00 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT $ readline: warning: rl_prep_terminal: cannot get terminal settings I did some research on the rl_prep_terminal: cannot get terminal settings error message, but didn't find anything. I checked if the proper devices were setup inside the vserver. I am not sure what should be there, but I haven't changed anything and it did work before the upgrade..

Re: [Vserver] vserver gentoo, anyone?

I've never even seen gentoo, I'm just getting the ISO's onto my system now to burn CD's to see what the installation is like. A buddy of mine says that everything compiles from source as part of the installation and took his system an awfully long time (12+ hours) to get set up on a PIII-1Ghz; is that about right? If you don't even know gentoo why do you want to use it in a vserver environment? No matter which distro you use, you will need a fairly good knowledge of the inner working of the distribution you choose to get things running smoothly.. Now, regarding the actual topic, I've been using Gentoo hosts and vservers in production environment for web and email hosting (Main applications I run are Apache, Qmail, mySQL, Tomcat and postgresql). It does work very well. I would recommend staying away completly from gentoo's init system inside the vserver. I did managed it to somewhat work but it must be customized quite a lot. Basically, all boot level scripts must be disabled, but most application's init scripts will depend on them, so you need to modify pretty much all the script you need. The /sbin/rc script also performs quite a few nasty stuff you don't want to be happening inside the vserver (mounting a tmp filesystem for example) so it needs to be tweaked a bit too, which makes things hard to maintain for such a simple task. After all, you only need an automated way to start a few processes... I've recently come up with a much easier solution that works even better. The vserver script will execute /etc/rc.d/rc inside the vserver when starting and stopping it. This file is the rc script on RedHat I guess, and it does not exist on Gentoo. So I created one from scratch which looks like this: - -8--- #!/bin/sh case $1 in 3) /etc/rc.d/boot.sh ;; 6) /etc/rc.d/halt.sh ;; esac - -8--- Then I created a script named boot.sh containing the commands to start the needed services and an halt.sh that stops them.
