Re: [Jailkit-users] Ubuntu 11.04 64-bit

[Michael Schwinges]

Thank you so much for replying Olivier. Your email was just what I needed to point me where to look.

I followed the strace instructions at http://olivier.sessink.nl/jailkit/howtos_debug_jails.html and by checking the open calls for libnss I could see that /lib/x86_64-linux-gnu/libnss_compat.so.2 wasn't in the jail. I copied it into the corresponding directory of the jail and I could sftp in perfectly.

Thank you again :-)

Kind regards,

Mike

Hi,

Can anyone assist me with the following? I compiled and configured
jailkit following the instructions on the web site, and when I try to
sftp address@hidden I get the following message in auth.log:

work for Ubuntu 11.04. I have two other servers - both 32-bit - where
the generic instructions just worked beautifully.

probably some of the libnss*.so 64bit files are missing. Look at the example jk_init.ini, the examples are mostly for 32bit systems. You probably need to adjust them a bit for 64bit systems.

jk_lsh tries to get the user information using the standard getpwnam() library call. This call uses the libnss plugins to actually get the information from files/ldap/nis etc.
