RE: [Jailkit-users] how-to add ftp access to ssh only jail?

[Josh Cole]

Oliver,

I finally had some time to use your suggestions below...

When using jk_cp to copy over the ftp client to the jail and its
returning the following error:

address@hidden home]# jk_cp -j /home/chrootusers /usr/bin/ftp
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or
directory

address@hidden home]# cat /etc/ld.so.conf
include ld.so.conf.d/*.conf

address@hidden home]# cat /etc/redhat-release
CentOS release 5.3 (Final)

I am able to ssh into the server but get the following error as well:

bash-3.2$ ftp localhost
ftp: ftp/tcp: unknown service
bash-3.2$

Any advice?

Thanks again,
Josh

sorry I misunderstood you.

adding an ftp client to a jail:

add jk_init section 'netbasics' to the jail, these include the files
required to do DNS lookups and things like that.

copy the ftp client to the jail with jk_cp

test it (see the howto on jail debugging), if it does not work use for
example strace to find out which files are not found in the jail.

regards,
   Olivier
