Installing Update 1 of the Sendmail Patch for NEXTSTEP Release 3.1 & 3.2

These instructions show you how to install the sendmail patch on NeXT and Intel-based computers running NEXTSTEP(TM) Release 3.1 or Release 3.2. The patch is distributed in an Installer package file named SendmailPatch.pkg.

Two versions of sendmail are provided with NEXTSTEP Release 3.1 and 3.2: sendmail (version 5.67) and sendmail.old (version 5.52). Late last year, the Computer Emergency Response Team (CERT) identified a handful of security problems with NeXT's versions of sendmail. These problems are described in CERT Advisories CA-93: 16 and CA-93: 16A. SendmailPatch.pkg contains copies of sendmail and sendmail.old that fix these security problems.

1. If you received the SendmailPatch.pkg file via NeXTmail(TM) or another electronic source, place a copy of the file in a location where you can access it when you log in as root.
2. Log in as root.
Only the superuser, root, can install the package. If you're not sure how to log in as root, see your system administrator.
3. If you received the SendmailPatch.pkg file on a floppy disk, insert the disk in the floppy disk drive and choose Check for Disks from the Workspace Manager(TM) application's Disk menu. When the disk icon appears in the File Viewer, double-click it to open it.
4. Double-click the SendmailPatch.pkg file.
5. Click the Install button in the Installer package window. When the panel asks you what kinds of computers you want to install the software for, select the kind of computer you're using and click Install. Then click Continue in the panel that warns you you're about to overwrite existing files.
6. When the installation is complete, choose Quit from the Installer menu.
7. Choose Log Out from the Workspace menu and then click the Restart button in the Login window.

Note: You must restart your computer after installing the package.
The next time you start up your computer, it will take advantage of the new versions of sendmail.
