RE: [Jailkit-users] closed connection for sftp in a chrooted jail

[Russ Lavoie]

The only shell I have enabled is sftp (same as the openssh 4.2.x
versions).  I do have logging running, but the only place I can find
anything talking about jk_xxx is in /var/log/messages and
/var/log/secure.

Here is my /etc/jailkit/jk_socketd.ini

# example
#[/home/testchroot/dev/log]
#base = 1024
#peek = 10240
#interval = 2.0

#[/var/ftp/mike/dev/log]
#base=512
#peek=2048
#interval=10

[/var/ftp/dev/log]
base=1024
peek=10240
interval=10

Here is /var/ftp/etc/jk_lsh.ini

[mike]
paths=/usr/bin, /usr/lib, /usr/libexec
executables=/usr/libexec/openssh/sftp-server, /usr/bin/scp

Here is the /var/ftp/dev/ directory.

address@hidden dev]# ll /var/ftp/dev/
total 0
srw-rw-rw- 1 root root    0 Nov 20 02:57 log
cr--r--r-- 1 root root 1, 9 Nov 17 02:39 urandom

here is the users home directory.

address@hidden dev]# ll /var/ftp/home/
total 4
drwx------ 3 mike mike 4096 Nov 17 02:40 mike


I am using WinSCP and regular linux to linux does not work.

This is the error when I am using WinSCP 

Connection has been unexpectedly closed. Server sent command exit status
127.

I can use the SFTP shell when I am using a user that is not chrooted
using jailkit.


I followed the following link step by step.  (just so you know the setup
steps I went through)

Using these same steps I can create another sftp site on any other
system using 4.2.x.  But once I use 4.3 it breaks (even if I had it
installed and working right after the upgrade it stopped working)

Thanks!

Russ

which shell do you use inside the jail? do you have logging enabled and
running inside your jail?
