[scponly] chroot question

[Roland Lammel]

You probably need to find your dynamic-loader lib which might simply be named differntly.

For example on one of our Suse boxes its named like this:
-rwxr-xr-x    1 root     root        94543 Sep 20  2001 /lib/ld-2.2.4.so
lrwxrwxrwx    1 root     root           11 Feb 18  2002 /lib/ld-linux.so.2 -> ld-2.2.4.so

Now that you found your libc you can use
shell> ldd /lib/libc.so.6
         /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

To find out the libs it needs, so in my case it's /lib/ld-linux.so.2

Best regards
