Re: [Jailkit-users] jk_init, jk_cp, and Gentoo /lib64 & UID does not have a name on RHEL ES 3 - AMD64

[sleahy]

Hi,

I got errors over the last few days
after installing jailkit 64bit on a RHEL ES3 AMD64 bit server too.

The error message I was getting was
as follows;

*jk_lsh[5342]: uid 502 or gid 505 does
not have a name*

Oliver, you mentioned in your reply that the user 502 must not have been
mentioned in /etc/passwd, so I checked all of this but
everything was correct.

In the end, it turned out to be that
files were missing from the /lib64 directory, '/lib/64/libnss_files*.  
It would appear that not all library files are copied over with the jk_init
program, so I used jk_cp again to chroot directory from source and then
it worked fine.

Regards,

Suzanne.

Subject	[Jailkit-users] jk_init, jk_cp, and Gentoo /lib64

I went through the instructions for installing and configuring
jailkit found on the website (using both the 2.0 release and the cvs snapshot).
 My system is an AMD64 running Gentoo, kernel 2.6.17-gentoo-r4.  When
I would try to log in with my jailed user both through ssh and via 'su
- username', I wound up with errors like this: 
/bin/bash: error while loading shared libraries: libc.so.6: cannot open
shared object file: No such file or directory

Looking in <chroot>/lib and <chroot>/lib64, it appeared that
all the libraries were in place.  After a while, on a whim, I decided
to use jk_cp to copy the libs manually (rather than through jk_init as
in the install guide).  I got the libs needed for bash copied over,
logged in successfully, and tried executing some commands, which of course
needed different libs.  I eventually wrote a simple shell script to
copy over all the libs from /lib64.  Everything seems to be working.

My question is, did I miss something in the install or is this something
weird about AMD64 or Gentoo-specific installs?  I looked through the
message archives, but I couldn't find much other than advice to make sure
the libs were there (which they appeared to be at first). 

BTW, now that I have it working, I love jailkit.  Great work!
