chroot jail

[liljohn]

100% newbie to Linux.

Work has an older version program that requires glibc 2.3.x in order to run correctly. Security folks are dictating that the kernel MUST be 2.6.30 or higher (which comes with glibc 2.4.x). If I'm reading what's said above correctly, I need to install both the updated/patched kernel, create a chroot jail, then install the older kernel in that chroot jail and point (somehow) the program to use that older glibc?

Using CentOS 5 at this time for the kernel, patched to 2.6.30 (learning experience there).

Now, how do I create a chroot jail, install and reconfigure an older kernel within that chroot jail, and point the program to use that older glibc?

Any help would be greatly appreciated and tia.

Hey liljohn,

I'd probably start looking at the glibc compatibility libraries first:

Can't post links but try searching for compat-glibc-2.3.4-2.26.i386.rpm

You may then need to set the LD_LIBRARY_PATH to include the 2.3 libraries before launching the executable.

Cheers,
Tom
