- Essential Patches to NetWare 386 v3.10 rev. A
-
- Several patches have been released for NetWare 386 v3.10 rev. A, which are
- considered essential for the operating system's optimum functionality.
- Each of these patches should be loaded at every installation of NetWare 386
- v3.10 rev. A. (See Technical Bulletin 277 for an explanation of patch
- types)
-
- The following list identifies and describes the patch and provides, in
- parentheses, the filename on NetWire to download.
-
- CACHEFIX.NLM is a semi-static patch that corrects the caching problem.
- Under heavy usage when data is read from cache before the cache is
- written to the disk, the data read could result in the return of
- erroneous data. If cached data is read and rewritten to cache, the
- corruption would be saved to disk. If the data is not changed in
- cache, the data will be saved correctly. This problem exists
- primarily with random access applications (for example, database
- servers). (CACHFX.ZIP)
-
- FIXOPEN.NLM is a dynamic patch that overrides the Read Only security of
- v3.10a, providing pre-v3.10a access functionality. In NetWare
- versions previous to NetWare 386 v3.10 rev. A, a file flagged with
- Read Only rights could be opened by applications using a Read/Write
- open DOS call. This deficiency was corrected in the v3.10a security
- enhancements. However, many applications are written using file open
- calls requiring Read and Write rights. If these applications are used
- with v3.10a, the errors "File not found" or "Access denied" may appear
- when attempting to open files flagged as Read Only. (FXOPEN.ZIP)
-
- PASSFIX.NLM is a dynamic patch that corrects a very rare security
- shortcoming which has been identified by Novell. This patch is for
- NetWare 386 v3.10 rev. A servers. For most Novell customers who have
- intruder detection set on, this security weakness will not pose a
- problem. Novell recommends that all customers turn intruder detection
- on. If a customer has greater concerns for security, this corrective
- patch should be applied. (SEC386.ZIP)
-
- WDOGFIX.NLM is a semi-static patch that corrects a problem where the server
- comes to an abnormal end with the message "Abend: Total sprintf string
- length was too long (Error code 00000000)." This Abend could occur at
- any time, but occurs more frequently if the console parameter "Console
- display watchdog logouts = ON" was set. This patch also fixes a
- problem that displays invalid characters or user names on the console
- screen when the watchdog clears a user's connection. (WDOGFX.ZIP)
