Re: [Jailkit-users] Can't login - Connection dropped

Rich,

That was it!   I had actually edited the file properly at /etc/jailkit/jk_lsh.ini instead of /jail/etc/jailkit/jk_lsh.ini.    As soon as I added the appropriate entries to the file in /jail/etc/jailkit everything began working well.

Thanks for your assistance!
Bob

Hi,

I think you are running a restricted chrooted shell which limits what files can be executed.

Try editing /etc/jailkit/jk_lsh.ini to enable access to the required binaries or try chaging the shell in /jail/etc/passwd to be bash rather than jk_lsh.

I'm attempting to use Jailkit on Suse Enterprise 11 R2 unsuccessfully.   I've created a jail at /jail and a user named test within the group uploaders.   This user should only have access to sftp.

I've done the following:
1) Edited jk_init.ini.   I've changed the paths assignment within the [sftp] section to include /usr/lib64/ssh/sftp-server.
2) jk_init -v -j /jail sftp scp
3) jk_init -v -j /jail jk_lsh
4) jk_jailuser -v -j /jail test

When I attempt to sftp using the user test the connection is dropped immediately after login.   The following appears in the logs:
Mar 26 08:46:57 files sshd[10679]: Accepted keyboard-interactive/pam for test from 10.1.1.10 port 63647 ssh2
Mar 26 08:46:57 files sshd[10686]: subsystem request for sftp
Mar 26 08:46:57 files jk_chrootsh[10687]: now entering jail /jail for user test (1001) with arguments -c /usr/lib64/ssh/sftp-server
Mar 26 08:46:57 files sshd[10686]: Received disconnect from 10.1.1.10: 11: disconnected by user

The data for this user in /etc/passwd and /jail/etc/passwd looks fine.  

/etc/passwd:
test:1001:1000::/jail/./home/test:/usr/sbin/jk_chrootsh

/jail/etc/passwd:
test:1001:1000::/home/test:/usr/sbin/jk_lsh

Can anyone give me any suggestions regarding what I've done incorrectly?   I can't seem to locate this problem.

Thanks,
Bob
