[other] SSH Cjhroot Jail 24 weeks 6 days ago

Hello,

I'm trying to set up a chroot jail for a user in /var/jail, following this guide http://allanfeid.com/content/creatin...ail-ssh-access.

I've got everything set up, but upon attempting to log in with the user, I get:

Code: /var/jail/bin/bash: No such file or directory Connection closed. I've verified that /var/jail/bin/bash does exist, which is the bash that I want the user t

I posted on the freebsd forums. I've been trying all night and I've made some progress but still I can't connect to the internet from my freebsd jail.

Please just give me a hint here.

I get the following inside the jail if I do nslookup www.google.com :

;; connection timed out; no servers could be reached

So, I can't seem to install stuff inside the jail.

I have some difficulties to start 2 jails on the same host. When the first jail is running, i can access this jail by ssh and http (this jail running nginx). But when i start the second jails, i lost first jail connection and i can't join the jail from ext.

I've got this chroot jail all setup. I try to run Firefox in it, and get the message:

"Gtk-WARNING ** cannot open display: "

I know I have to invoke Firefox with --display= something. I probably also have to set the DISPLAY environmental variable to something as well. But I've tried all kinds of combinations, and can't get it to work in the chroot jail.

Thanks.

I installed jailkit on my CentOS 5.8 server, and configured it according to the online guides that I found.

If the users logs in, he starts in / of the chroot (Which is /var/jail on the real machine). I would like him to start in his home-dir. Also, he seems not to load any of his profile-files (.bash.rc etc). I followed this tutorial to create the chroot environment.

Migrate FreeBSD jail 28 weeks 6 days ago

I need to create a freebsd jail for web hosting, that will be frequently migrated between hosts.

How feasible is it? Can I use domains instead of IPs? can I use wildcard IPs?

I need this to benchmark different hw/sw configuration against a known resource hogger.

I am performing the following on FreeBSD 9.0-STABLE:

mount_nullfs /foo /jail/foo

After that, from within the host system, the mount works.
