Signing an Exit in UNIX - Red Hat Linux 3 or Solaris 8

Unlike in Windows, UNIX does not include a Configuration program to sign an exit. There are, however, three ways to sign the default exit in UNIX, and two ways to sign a user-supplied exit in UNIX.

Default exit in UNIX - Red Hat Linux 3 or Solaris 8

There are three ways to sign the default exit in UNIX.

  1. The Optim Setup program, which allows you to sign the default exit as part of the installation process, as described earlier in this appendix. (If you want to sign a user-supplied exit, you must manually run a script file after installation is completed.)
  2. The opmdsign script file, located in the rt/sbin directory. You can run this script at any time following installation to switch to the Optim default exit. (The letter “d” in the script name indicates that it is used to sign the default exit.)
  3. The pr0sign program.

User-supplied exit in UNIX - Red Hat Linux 3 or Solaris 8

There are two ways to sign a user-supplied exit in UNIX.

  1. The opmusign script file, located in the rt/sbin directory. You can run this script at any time following installation to switch to a user-supplied exit. (The letter “u” in the script name indicates that it is used to sign a user-specified exit.)
  2. The pr0sign program.

You can use the pr0sign program to sign either the default exit or a user-supplied exit. Before you run the pr0sign program, however, you must ensure that the environment is set up. The opmdsign and opmusign scripts will both set up the environment and call pr0sign.

You must sign an exit for each installation of Optim on a UNIX server. If you copy a signed exit from one installation to another, you must sign the exit again at the target installation.
