Shared Libraries

Shared libraries are units of code, such as glibc, which are used by a number of applications and services.
Applications utilizing a shared library typically load the shared code when the application is initialized, so any applications using the updated library must be halted and relaunched.

To determine which running applications link against a particular library, use the lsof command as in the following example:

This command returns a list of all the running programs which use TCP wrappers for host access control. Therefore, any program listed must be halted and relaunched if the tcp_wrappers package is updated.

The latest CentOS 5.3/RHEL 5.3 updates for openssh (openssh-4.3p2-36) introduce the dependency on the libfipscheck.so.1 library supplied by fipscheck-1.0.3-1 RPM, but this RPM is missing in default file system template for ssh.

Log in as root to your PPCPL box.

Open the /etc/virtualhosting/filelists/ssh.sh file using a text editor:

Make sure that the file looks like:

$RPM_BIN -q nss nspr > /dev/null 2>&1 && \
cat <<EOF
S,rpm:nss
