sudo /usr/bin/chroot /home/chroot /bin/su - xxx| /bin/su: user xxx does not exist


Hello!

I tried to set up a chroot dir.

Everything is working but the su command.

1.) Yes, I have a passwd + goup under /home/chroot/etc
2.) No, I would not like to use anything like rssh or a 'patched' openssh
3.) Yes I RTFM but it does`t work
4.) Yes, I recompiled the su as wanted but ....no success...yes I did not forget the libs

sudo /usr/bin/chroot /home/chroot /bin/su - xxx
/bin/su: user xxx does not exist

Thanks for every idea!

What distro are you using? Do you have any necessary PAM stuff in your chroot (swhouldn't need them, but you never know..). First though, check for typos i n the chrooted /etc/passwd (I once spent hours searching for a problem that turned out to be an out of place colon :-().

you probably didn't copy the name switch service plugin libraries to the jail. try a locate on libnss

are you aware that such a chroot jail setup is not secure? it is possible to break out of it.

if you want a secure jail, and some convenient scripts to create it, check out the jailkit project , I use it for accounts that can do only sftp and cvs to a chroot jail, and nothing else.

Target file system doesn't have /sbin/init or chroot /mnt/buildroot cannot run comman

Target file system doesn't have /sbin/init or chroot /mnt/buildroot cannot run command '/bin/bash' / 'su' 'env' u.s.w

usually if you make a live cd system
you would copy your system tree
to a directory like: /path/to/my/buildroot

if you use cp -a ; or cp -ar ;
the /lib64 , which is just a link to /lib
on debian like systems, - goes lost

and you receive this errors at boot time from the Kernel
or by tryeing to execute chroot as a result .

JUST SET THE ... LINK and everything would be ok
