setup_chroot.sh does not copy file /lib/libnss_files.so.2

[Chad Armstrong]

Binary package hint: scponly

I was getting the "connection closed" problem from SFTP clients until i copied libnss_files.so.2 to the chroot lib directory.

Ubuntu 10.04 LTS
scponly 4.8-4

I can confirm the bug and fix on 10.04 amd64

Bug exists on 10.10 as well.

I can confirm this bug under Ubuntu 10.10. Before I copied libnss_files from /lib to the $chroot/lib, scp and sftp would not work. Please to produce an updated package, as this is highly annoying and has been reported a long time ago. I'd produce an updated package in a whim but wonder who would trust it ....

So for all those who want to use scponlyc and get the following error: "user xyz not found" with xyz being the user ID of the chroot user, do the following under Ubuntu 10.10:

sudo cp /lib/libnss_files-2.12.1.so $chroot/lib
cd $chroot/lib
sudo ln -s libnss_files-2.12.1.so libnss_files.so.2

with $chroot set to your chroot root directory.

still exists in 11.04 (server 32bit)

patch doesn't work!

fix it:

sudo cp /lib/i386-linux-gnu/libnss_files-2.13.so $chroot/lib/i386-linux-gnu/

cd $chroot/lib/i386-linux-gnu/

sudo ln -s libnss_files-2.13.so libnss_files.so.2

with $chroot set to your chroot root directory

Downloaded and installed https://launchpad.net/ubuntu/precise/amd64/scponly-full/4.8-4.1

"cp /lib/x86_64-linux-gnu/libnss_files.so.2 /home/scponly/lib/x86_64-linux-gnu/" solved the problem.

SCPONLY not seems to be part of ubuntu anymore - missing it.
Probably there is a better solution for this by using a apparmor profile?
