DOWNLOAD AND APPLY THE PATCH

STEP 1: PREREQUISITES

Before you can apply the 1.1.21 patch:

1. Your current Kermit 95 version must be 1.1.17 or 1.1.20. If you have any other version of K95, you MUST PATCH UP TO VERSION 1.1.17 OR 1.1.20 before you can install the 1.1.21 patch. If there is some reason you can't do this, contact us at [email protected] and we will help you.

2. Your PC must have an Intel or compatible processor and the operating system must be Windows 95, 98, ME, NT 4.0, 2000, or XP. The Alpha and PowerPC versions of Windows NT are no longer supported; Windows NT 3.51 and earlier are no longer supported. The OS/2 version is not yet ready (CLICK HERE for more about OS/2).

STEP 2: CHOOSE THE APPROPRIATE PATCH

CLICK HERE if you have trouble downloading a patch file. The patch files are:

i17-21.exe

Patches a non-secure copy of K95 1.1.17 to non-secure 1.1.21.

i20-21.exe

Patches a non-secure copy of K95 1.1.20 to non-secure 1.1.21.

i17-21c.exe

Patches a non-secure copy of K95 1.1.17 to secure 1.1.21.

i20-21c.exe

Patches a non-secure copy of K95 1.1.20 to secure 1.1.21.

i17c-21c.exe

Patches a secure copy of K95 1.1.17 to secure 1.1.21.

i20c-21c.exe

Patches a secure copy of K95 1.1.20 to secure 1.1.21.

If you are in Iraq, Iran, Libya, North Korea, Sudan, Syria or Cuba... You must apply the appropriate NO STRONG ENCRYPTION patch:

1.1.17 to 1.1.21:

Via FTP: ftp://kermit.columbia.edu/kermit/k95/patches/i17-21.exe
Via HTTP: http://www.columbia.edu/kermit/k95patch/i17-21.exe

1.1.20 to 1.1.21:

Via FTP: ftp://kermit.columbia.edu/kermit/k95/patches/i20-21.exe
Via HTTP: http://www.columbia.edu/kermit/k95patch/i20-21.exe

If you are NOT in Iraq, Iran, Libya, North Korea, Sudan, Syria or Cuba...

You have your choice of secure or non-secure patches. The non-secure patch upgrades a non-secure copy of K95 1.1.17 or 1.1.20 to a non-secure copy of K95 1.1.21. The secure patches convert non-secure and secure copies of 1.1.17 or 1.1.20 to a secure version of 1.1.21, including its new SSH client. Before choosing a patch, you must know whether your current copy of K95 has or does not have the security patches installed. If you don't know, type the following commands at the K95 prompt:

  K-95> define test if available encryption echo Secure
  K-95> test

If K95 echoes "Secure" then you have the security patch.

• If you have K95 1.1.17 with security patches installed, you must apply the i17c-21c.exe patch.
  CLICK HERE for export clearance and to access the patch.

• If you have K95 1.1.20 with security patches installed, you must apply the i20c-21c.exe patch.
  CLICK HERE for export clearance and to access the patch.

• If you have K95 1.1.17 or 1.1.20 without security patches installed, you can choose:
  1. The i20-21.exe NO STRONG ENCRYPTION patch if you don't want security:

     1.1.17 to 1.1.21:

     Via FTP: ftp://kermit.columbia.edu/kermit/k95/patches/i17-21.exe
     Via HTTP: http://www.columbia.edu/kermit/k95patch/i17-21.exe

     1.1.20 to 1.1.21:

     Via FTP: ftp://kermit.columbia.edu/kermit/k95/patches/i20-21.exe
     Via HTTP: http://www.columbia.edu/kermit/k95patch/i20-21.exe

  2. The i17-21c.exe or i20-21c.exe patch to add security.

STEP 3: APPLY THE PATCH

After downloading the patch file, i17-21.exe, i17-21c.exe, i17c-21c.exe, i20-21.exe, i20-21c.exe, or i20c-21c.exe:

1. Make sure it is in your Kermit 95 program directory; that is, the same directory where K95.EXE is. If it is not, move it there. The patch doesn't work if you run it from any other directory.

2. Close all Kermit 95 windows and applications.

3. To apply the patch, simply execute the patch file. You can do this in any of the following ways:
   • By double-clicking on its icon.
   • In the Start -> Run dialog.
   • In a command window, by typing its pathname.

Your Kermit 95 version should now be upgraded to 1.1.21. Note that the Secure Version of 1.1.21 does not support the KFTP.EXE program that was distributed with secure versions of K95 1.1.20. KFTP.EXE is not compatible with the security libraries shipped with 1.1.21 and is deleted when the patch is applied. A secure and scriptable FTP client is now built into K95.

If patching was not successful, please read the following sections.

HOW DOES THE PATCH PROCESS WORK?

• First it looks for the current name:

  If the file cannot be found it produces an error message:

  ENTRY: C:\K95\DOWNLOAD\apage.ksc
  warning wpt0015: Old File does not exist

• If found it checks a CRC, length and some other items to confirm that it is the correct file.

• If the test fails, an error message is given:

  ENTRY: C:\K95\DOWNLOAD\READ.ME
  warning wpt0036: Old File not found. However, a file of the same name was found. No update done since file contents do not match.

These messages are either non-fatal (the patch process will continue) or fatal (the process will be rewound) depending on the file being patched. Errors patching the following files are fatal:

• K95.EXE
• K95DIAL.EXE
• DIALER.DAT

Errors patching all other files result in non-fatal warning messages.

If a fatal error occurs it is most likely because:

• You are trying to install the wrong patch on your installation; or:
• You are trying to patch a Beta-test or other non-release version; or:
• One or more of the files you are trying to patch is open; or:
• You are not executing the patch file out of the K95 program directory.

Non-fatal errors occur either because you deleted or replaced a file in the distribution or accidently altered it while reading the file with NOTEPAD or other editor.

If there is not an error, the patch program applies the patches from the patch file to each old file, creating the new version of the file, and placing the old copy in a BACKUP subdirectory, which it creates if necessary.

The results of the patch process are recorded in a file called PATCH.ERR. If you experience problems applying patches that are not explained below, then send a report by email to [email protected], enclosing a copy of the PATCH.ERR file.

MICROSOFT DLLS REQUIRED ON WINDOWS

Kermit 95 1.1.18 and later on Windows 95 and NT require the Microsoft MSVCRT.DLL library. It should be included as part of Windows, but isn't, and so is generally installed whenever you install an application. As of 1.1.19, this DLL is installed for you automatically by the patch process if you need it.

---

POSSIBLE PROBLEMS AND HOW TO AVOID THEM

• Make sure you are not trying to patch a test version. If you were testing a prerelease of the new version, you have to put back the real release before installing a patch. Patches do not work on non-released Kermit 95 versions.

• Make sure you have enough disk space. At least 10MB of free space on the disk containing your K95 directory is needed. If you don't have this much, then you can use "patchdos -nobackup", but if you do that it won't be easy to back out of the patches.

• Make sure you are using the right patch. The base version number of the patch must match the base version of K95 that you are patching. As of the version 1.1.13 patch, if your DIALER.DAT, K95.EXE, and K95DIAL.EXE are not the right version, no patches are installed at all.

• Make sure you are in the right directory. The patch file and the patch program should be in your Kermit 95 program directory, and the Kermit 95 directory should be your current directory.

• Any file that you have changed will not be patched. So, for example, if you have changed any of the hostmode or sample scripts, they won't be patched. If you changed the DIALINF.DAT file (the original dialer database), it will not receive any patches. K95CUSTOM.INI is never patched since it is not part of the software distribution, but is created for you by the SETUP program, and in most cases, edited from time to time afterwards.

• If a file is in use, it won't be patched. Therefore it is essential that you shut down all K95 sessions and the Dialer prior to patching. You can doublecheck by typing Ctrl-Alt-Del and looking at the task list.

• If a file is read-only, it won't be patched. Thus if you have set the K95.EXE, K95DIAL.EXE, DIALINF.DAT, or other files read-only (e.g. on a file server), you will need to set them read-write for the patching process.

• If you have compressed or packed any of your K95 files (e.g. with EXEPACK, LXLITE, etc), they will not be patched.

• If you have a CTL3D32.DLL file in your system, but the one included in the K95 patch is newer, the patch procedure will attempt to replace it. But if it is in use (e.g. because you have another GUI application loaded), the patch procedure will report that "The preexisting file is in use and cannot be deleted". No harm done. If the K95 Dialer works for you, there is no need to update your CTL3D32.DLL file.

• If the patch process complains about a missing K95CRYPT.DLL file, you can safely ignore this message.

BACKING OUT OF PATCHES

You can back out of a patch and restore your previous version as follows:

1. Open a Command window
2. CD to your Kermit 95 directory.
3. CD BACKUP
4. REN UNPATCH.BAK UNPATCH.BAT
5. UNPATCH

If you applied more than one patch, or you tried applying the same patch multiple times, there will be several different UNPATCH.BAT files, but with different (and perhaps nonsensical) names, starting with "UNPAT". Thus to back out to any particular level, you'll need to run the UNPAT*.BAT files in reverse chronological order, as indicated by their file dates, shown by:

  DIR /O-D

After you have satisfied yourself that your patched version of Kermit 95 is working satisfactorily, you may safely remove the contents of the Kermit 95 BACKUP directory.
