I need to install, upgrade, or uninstall VShell® for UNIX on my Mac OS X system.

Required Libraries

The following libraries must reside on your system for the VShell for UNIX installer to complete successfully:

Mac OSX 10.2

• libz.1.1.3.dylib
• libpam.1.0.dylib
• libSystem.B.dylib
• /System/Library/Frameworks/Carbon.framework/Versions/A/Carbon

Mac OSX 10.5 (Intel x86)

• libz.1.dylib
• libpam.1.dylib
• libstdc++.6.dylib
• libgcc_s.1.dylib
• libSystem.B.dylib

Install

To install VShell for UNIX, follow these steps:

Note: You must have root permissions to install VShell.

1. Download VShell from the VanDyke Software web site. Make a note of the MD5 checksum listed below the download link that you use. You can ensure that the downloaded file has not been corrupted by comparing that number to the number generated by running the following command on the downloaded file:
   

    md5 <vshell filename>

2. Clear port 22. By default, VShell uses port 22. Before installing VShell, stop all other services that run on port 22.
3. Go to the folder where you downloaded the VShell installer package.
4. Open the following file:
   

    vshell-<version number>-<build number>.osx.dmg

5. Run vshell.pkg
6. Answer any installer prompts.
   
   This will create the following files and install them to the indicated pathnames:
   
   /usr/local/sbin/vshelld
   /etc/init.d/vshelld
   /usr/local/bin/vsh
   /usr/local/bin/vsftp
   /usr/local/bin/vpka
   /usr/local/bin/vcp
   /usr/local/bin/vkeygen
   * /usr/local/etc/vshelld_config
   * /usr/local/etc/vshelld_primes.txt
   * /etc/pam.d/vshelld
   /usr/share/doc/vshell-<version>/history.txt
   /usr/share/doc/vshell-<version>/readme.txt
   /usr/share/doc/vshell-<version>/VShell_EULA.pdf
   /usr/local/order.txt
   /usr/local/man/man1/vcp.1
   /usr/local/man/man1/vsh.1
   /usr/local/man/man1/vsftp.1
   /usr/local/man/man1/vpka.1
   /usr/local/man/man1/vkeygen.1
   /usr/local/man/man5/vshelld_config.5
   /usr/local/man/man8/vshelld.8
   /usr/local/etc/vshelld_config.default
   
   
   * These files will not be replaced if they already exist.
7. Once the package has been installed successfully, you can quit the installer.

Upgrade

To upgrade VShell for UNIX, repeat the installation instructions above.

Note: You must have root permissions to upgrade VShell.

You should not remove the host keys when doing an upgrade unless you want them to be regenerated. If you do choose to regenerate the host keys, all users using the service must re-load the host key for the system.

Uninstall

There is currently no uninstall application for Mac OS X. To uninstall VShell for UNIX, you must manually remove the installed files (listed above) and the installed folder:

Library/StartupItems/vshelld

Note: You must have root permissions to uninstall VShell.

Known Issues

The following is a known issue with the VShell server:

• Client authentication using X.509 certificates is not supported on VShell for Mac OS X.
