OpenSSL: Strong Web Server Security for MPE/iX

OpenSSL consists of implementations of the Secure Sockets Layer (SSL) protocol and the Transport Layer Security (TLS) protocol, a full-strength general purpose cryptography library, and associated command line utilities for encrypting and decrypting files, managing X.509 authentication certificates, composing and validating S/MIME e-mail, and much much more. This distribution is unsupported freeware that has been ported and packaged by HP for use on MPE/iX. This software has been minimally tested. HP does not guarantee updates or problem fixes for this freeware.

3000 NewsWire: Suprtool Update From A Table

The July issue of the 3000 NewsWire has an article about Suprtool's latest enhancement: updating fields from a table of values.

For some time, users have been aggressively asking us how to update a field in a dataset, or even a file, with a value from another file, based on a key. A classic example: Your boss comes to you with a list of new prices for certain parts and asks you to update the Part-Master dataset. Big News: You can now do this easily in Suprtool. Starting with pre-release 4.4.10, just load the new prices into a Table, index by the product number (prodno), then Extract the price field from each record and replace it with a $lookup on the table.

Robelle Tech: IMAGE Internals

The latest Robelle Tech column in the July 2001 issue of the 3000 NewsWire is now available on the web:

IMAGE is the database of the HP e3000 system, and some knowledge of how it works is useful for anyone doing IT work on the system. “Master Datasets” are one of the storage types of IMAGE and their job is to store records when there is one record expected per unique key field (also the search field). For example, one customer record per customer number. IMAGE uses a mathematical formula called a hashing algorithm to transfer the key value into a record number within the master dataset. This “hash location” is the first place where IMAGE tries to store the record. Figure 1 shows a hashing algorithm with a collision occuring in the same block

Qedit

QWIN: Get Access to a File's Path

When dealing with POSIX files (or any files on UNIX), you often encounter long file name paths which it would be quite difficult to type accurately by hand. For example,

/users/progdev/projects/01admin/phase1/src/plan.html

or much longer and more obscure "paths" to files!

You can open these files in Qedit for Windows by navigating through the directory window with your mouse, but often you need to enter the full file name into a host-command. A typical example is a CD command to the directory containing the file.

Qedit for Windows has a simple option to make the pathname of any open file easily accessible. Just Right-Click in the text window and select Copy pathname to clipboard. Now you can paste the pathname of your file into a script you are building, or the QWIN host-command window, or even a terminal emulator window.

Suprtool

Suprtool: Working with Single-Byte Integers

There may be times when you need to doing some computation on 1-byte integers. Although Suprtool allows you to define a 1-byte integer, it gives you a warning message about how unuseful it is.

define tiny,1,1,integer
Warning: Length of 1 is of limited use for the data type INTEGER

You will find that you cannot do the usual arithmetic operations on these 1-byte integers. The solution is to extra them as 2-byte integers by padding them with a leading binary zero, then do another pass through the output file to work with the resulting 2-byte integer. For example, this is what you would do if you need to add two 1-byte integers together:

  input yourfile
  define tiny1,1,1
  define tiny2,2,1
  ext ^0,tiny1, ^0,tiny2
  out tmp
  xeq


  input tmp
  define num1,1,2,integer
  define num2,3,2,integer
  define sum,1,2,integer
  ext sum = num1 + num2
  out result
  xeq

We didn't make "tmp" a self-describing Link file because we needed to redefine the 4 byte fields as two 2-byte integer fields in the second pass, so passing on the structure from the first pass was of limited value. It was clearer and easier to just Define the num1 and num2 fields from scratch.

qedit

Host-Based Qedit: Copying the Same Block Many Times (Visual Mode)

One common editing function in Visual mode is to copy the same text to several different places. Users often mark the text they want to copy, add it at one place and then go back and mark the original block again. This is not necessary because cut-and-paste operations save the lines they process in a temporary file called "Hold0". To find out how to copy from the Hold0 file again, click the link above.

Suprtool: Manuals in PDF and HTML

We have converted our production Suprtool manuals into PDF format and an excellent HTML Help format. The PDF format is ideal for printing and the HTML Help format is ideal for browsing and searching. You can download these files from our web site now: We are in the process of updating these new doc files for the Suprtool 4.4.1 pre-release and converting the Host-Based Qedit files into this format. Hopefully this will be more convenient for our customers.

More on UNIX Temp Files

Dave Lo's article on UNIX temp files in our most recent newsletter generated quite a bit of feedback on the Robelle-L discussion list.

First, Glenn Cole (glenn_cole@non.hp.com) asked:

Under "Unix: Where Are My Temporary Files," it would be nice to hear the difference between /var/tmp and /tmp. (Actually, until this note, I did not know that /var/tmp exists!)

and Hans Hendriks of Robelle (hans.hendriks@robelle.com) replied:

According to HP's "HP-UX 10.0 File System Layout White Paper" (at http://docs.hp.com/hpux/onlinedocs/5963-8942/5963-8942.html) : /tmp is for "System Generated temporary files", while /var/tmp is for "Application Generated temporary files"

Further down, they elucidate: "/tmp is for system-generated temporary files. The contents of /tmp are usually not preserved across a system reboot. The choice of whether or not /tmp is cleaned up at boot time is left to the customer.The /tmp directory is private. Since many sites will delete files from /tmp at boot time, files that must be preserved should not be placed in the /tmp directory. Application working files should go in /var/tmp or /var/opt/. Files generated by the OS that must be preserved across reboots should go into the /var/tmp directory. "

...And yet further down, under /var/tmp: "2.2.3.13.12 /var/tmp /var/tmp is for user temporary files generated by commands in the /usr hierarchy. Files located here are preserved between system reboots. Temporary files generated by applications installed under /opt/ will use /var/opt/ for temporary files."

AFAIK, the same structure applies to HP-UX 11.x (but not to 9.x and older....)

and Ted Ashton (ashted@southern.edu) concluded:

I'd say you're still okay with /tmp. The different flavors of Un*x have different definitions of /tmp. Some have /var/tmp; some have /usr/tmp; some have neither, but all have /tmp. With due respect to the docs, if /tmp were really meant to be strictly for system files, wouldn't it have its permissions set so that mere mortals couldn't write to it?

Qedit

QWIN: Version 5.0.10 Released

We are pleased to announce the release of Qedit for Windows version 5.0.10. Click the link for details on what's new in this version:

The Favorites command of the File menu allows you to organize and keep track of documents you use most often. You can have all your favorite files in a single list or organize them into folders. You can have multiple folders and a folder can have subfolders.

The Find String dialog box has a number of enhancements. It now offers Search Reverse and Search Forward buttons, which set the direction of the initial search but are not remembered as the default for the next new search.

It is now easier to select large blocks of text. Place the insertion point at the start of the block and save the position using the Save Position command of the Mark menu. Browse the file to locate the end of the block. Place the cursor at that location and use the Select to Saved Position command of the Mark menu.

Plus many more improvements. You can download this latest version from: http://www.robelle.com/products/qwin/download.html As usual, if you have any questions or comments, do not hesitate to contact us.

Host-based Qedit: New Features

Qedit version 5.1 has been released into production with several valuable new features:

Searching for Multiple Strings: to match lines with more than one string in the same line, do list "bob" or "sam"

Changing Cobol Tags: to edit the tag area of a COBOL line (columns 73-80), do changet "bob-june"sam-july"

Specifying a Default Increment: to override Qedit's calculated line number increment when Texting a large file, do a Set Increment command and then do text bigfile,setincr

Posix command shortcut: to execute a command line through the POSIX shell, precede it with an exclamation (!).

Full-screen mode: now resets the terminal width when returning to line editing, recognizes and supports the QCTERM emulator from AICS.

Since we have switched to rolling-updates and multiple releases per year, customers with paid support will receive your Qedit update on their anniversary date (or sooner). For more information on this release, read the change document.
