Required libraries missing from some Linux distributions
NetBackup runs prechecks at installation and upgrade to determine if certain required operating system libraries are present. To run that precheck, the libnsl.so.1 and libcrypt.so.1 libraries must be present. Before you attempt an installation or upgrade, Veritas recommends that you search your Linux computer for these libraries.
NetBackup requires other operating system libraries for NetBackup to run correctly. Some distributions of Linux have removed these libraries from their core distribution. The NetBackup precheck successfully determines if any of these libraries are not present and informs you at install or upgrade time.
