Re: Can't login Jailed system
Apologies, I accidentally commented out the jail_dev and jail_proc liens in the rc.conf file, wasted everyone s time. Thanks for the help. :D Sam On Tue, Jun 30, 2009 at 12:29 AM, Jon Passki wrote: > On Mon, Jun 29, 2009 at 9:21 AM, Sam Wun wrote: >> I got the following errors now: >> >> # less jail_wwp1_console.log >> ps: empty file: Invalid argument >> Loading configuration files. >> /etc/rc: WARNING: $hostname is not set -- see rc.conf(5). >> ELF ldconfig path: /lib /usr/lib /usr/lib/compat /usr/local/lib >> /usr/local/lib/mysql >> a.out ldconfig path: /usr/lib/aout /usr/lib/compat/aout >> Creating and/or trimming log files:. >> Starting syslogd. >> Clearing /tmp. >> Starting local daemons:. >> Updating motd. >> Starting sshd. >> PRNG is not seeded >> Starting cron. >> Local package initialization:. >> ps: bad namelist > > Assuming you didn't build a kernel to exclude the random device, it > looks like you do not have a /dev filesystem mounted for your jail. > ssh needs some type of random device.

Try mounting a devfs in the path of your jail. If you are using /etc/rc.conf for this information, man 5 rc.conf, look at the "jail_devfs_enable" and "jail__devfs_enable" variables.

Sam, what Bjoern is alluding to is that SSH in the main system is probably running on all IP addresses on port 22/TCP. The jail(8) man page has a section called "Setting up the Host Environment" which you might want to review again. For SSH, check out /etc/ssh/sshd_config and look for "ListenAddress". If it is setup for the default setting of "#ListenAddress 0.0.0.0", then uncomment it and change that line in your main system to be the main IP address. Restart sshd (/etc/rc.d/sshd restart). You will probably have to restart your jail's sshd instances since they probably tried to bind to their IP address on 22/TCP unsuccessfully. (Or, just restart all of your jails if it's not a big concern, /etc/rc.d/jail restart.)

After about a month left the "jail" behind, now when I done a "/etc/rc.d/jail start" and ssh into it, I ended up login to the host system.

After I login 192.168.1.242, I ended up logged in twp1 which is my host system. Now I am stuck. I don't know how I logged in the jailed system a month ago. Can anyone shred some lights on me? Try to jexec 5 /bin/sh (5 is the jailID from the jls output) and check with ps if sshd is running inside the jail, and check the usual things are up and there. /bz -- Bjoern A.
