Jailshell Doesn't Allow 'ls'

[jonwatson]

Hi All,

New to cPanel, but not new to control panels in general. I'm preparing to migrate a server from ISPConfig to cPanel, but I can't seem to get any joy out of the jailshell. When a jail a user, that user can no longer ls his directory or create files...seems he no longer has permissions to his own directory. This snippet is from one such user in his own home directory:

jailshell-3.00$ ls
ls: .: Permission denied
jailshell-3.00$ touch test
touch: cannot touch `test': No such file or directory
jailshell-3.00$ mkdir test
mkdir: cannot create directory `test': No such file or directory
jailshell-3.00$

Any ideas what's going on here?

Thanks!

Get into the directory /home/virtfs/username/home/ from SSH and check the ownership and permission of the folder named username inside this directory. Make sure it has got the ownership username.username and permission 711.

I think perhaps I was a little hasty. Things just started working after a while.

When the issue with the jail shell persists a reboot of the server should solve it.

Hi,

Facing this same issue. The Permission denied was fixed after giving the correct ownership to the folder ''/home/virtfs/username/home/username". However, now when I try logging in via SSH and try accessing or listing any files I get nothing,

[digen@redux ~]$ ssh username@domain.com
username@domain's password:
Last login: Thu Apr 19 21:34:03 2007 from server.hostname
-jailshell-3.00$ ls -al
total 0
-jailshell-3.00$ ls -al
total 0
-jailshell-3.00$

The shell has been set to ''/usr/local/cpanel/bin/jailshell'' in /etc/passwd. The prompt to isn't changing to username@serverhostname.

This is happening for only one account. Also when I check the files in the user's home directory /home/username they are there.

Hi,

When login with problematic user type "pwd" and copy here the output.

I'm having EXACTLY the same problem. I have recreated this user MANY times, and I still have a problem with his SSH access. Changing his SHELL to a normal shell works fine. The user can logon, and do whatever he needs to, but this isn't desired.

Looking at another account, which works with jailshell, I get this:

So, there's some files in /home/virtfs/bonzai/home/bonzai/ but NOT IN /home/virtfs/oostdco/home/oostdco/

Now, logged in as the user oostdco, with jailshell access, I get this:

-jailshell-3.1$ pwd
/home/oostdco
-jailshell-3.1$ ls -la
total 0
-jailshell-3.1$ pwd
/home/oostdco
-jailshell-3.1$ cd public_html
-jailshell: cd: public_html: No such file or directory
-jailshell-3.1$

Then, I change this users shell to Normal Shell, and get this:

[oostdco@gandalf ~]$ pwd
/home/oostdco
[oostdco@gandalf ~]$ ls -la

Any suggestions? It's only happening with ths one account, all other accounts are fine

I have something similar. The home dir in virtfs/user/home/user is just empty. Is there any way I can recreate those (hard?) links to make it working?

WHM 11.11.0 cPanel 11.15.0-R17665

[VeZoZ]

I just had this issue with a client account and I made a ticket about it. The customer is willing to wait so we can figure out what causes this. So hopefully cPanel can get to the bottom of this and it won't be happening in the future.

[mynameanu]

This happens from time to time, and it is really easy to fix, simply umount the entire virtfs directory, then log back in to the SSH user, and it will be fine;

root@server [~]# umount /home/virtfs/<user>/home/<user>/
root@server [~]#
