(SCO Unix)FAQ - How can I make a printer that will print to a file? 
- Setting up a printer that will print to a file can be useful for any number of reasons. Here we set up two printers; one that prints to files in the user's home directory, and another that prints to a shared common area.
 
Microsoft feeling pinched? 
- Microsoft - yes, the guys sitting on those giant piles of cash - is cutting back on employee benefits.
 
Self Defense for Windows users 
- The very basics of protection for Windows users. Some of this applies to everyone, of course.
 
Are we there yet? (SCO Lawsuit) 
- The depth of ignorance always seems proportional to the willingness to have a strong opinion.
 
Running out of space for web logs 
- Damn! I hate running out of space.. though I hate paying for more space too.. Well, web access logs are easily compressed. A 30 MB access_log easily gzips down to a tenth of that.
 
Linux|Unix/Unix Viri 
- Sophos chief concedes Unix virus frustration due to multiple Linux kernel distributions.
 
Windows 98 128 bit DUNS 
- Somewhere there is some sad person who still cares about Windows 98 - this is for you, fella.
 
Gmail too creepy? 
- I recently did a Review of Gmail and also mentioned that some folks are very worried about the privacy concerns associated with Google storing their mail.
 
Unix License Plate 
- t might seem a little strange to choose that "Live free or die" motto. Yeah, there is FreeBSD, but generally Unix hasn't been anything close to free. However, this is a historical reproduction: The History of the UNIX License Plate
 
SCO Lawsuits drag on 
- The news of SCO's legal setbacks has been greeted by some as joyful, but as this article points out, setbacks are just setbacks, and don't mean the case is over. It certainly does mean that this part of the mess (who holds the copyrights) is confusing enough to warrant a trial.
 
SCO Roadmap 
- SCO Announces Broad Array of New Unix Products, Channel Support and Training Programs
 
Mozilla to the Rescue 
- Why put up with the shortcomings of Outook Express?
 
Microsoft Admin user 
- This has been fixed in Visata and Windows 7; yet another readon to ditch XP
 
Login auditing 
- Logging failed logins discusses some aspects of monitoring and logging login failures.
 
Transfer SCO Acucobol to Linux 
- The customer also told me that everything was written in Acucobol, and that he had source code too, and he had already bought Acucobol run-time for Linux but hadn't been able to get it working. We decided to first get the SCO system back up and then look at the Linux.
 
SCSI: An Old Dog That Keeps Learning New Tricks  by BigDumbDinosaur
- SCSI's ancestor, Shugart Associates System Interface, was publicly disclosed by Dr. Alan Shugart in 1979 in hopes of being accepted as an industry standard.
 
Groklaw reports SCO not developing Unix 
- A consultant says SCO is getting out of the Unix business. Yeah, though not necessarily by choice!
 
Mail bombs 
- Coincidentally, I get mailbombed shortly after not being nasty enough about SCO. Boy, I wish some morons would learn how to read!
 
Large USB drives 
- Where did these come from? I guess I've been sleeping too much again, because this caught me by surprise: 4GB USb 2.0 Pen Drive Flash Drive. The pricing doesn't thrill me, but the idea sure does.
 
Windows XP patches on CD 
- Having at least most of the recent patches available on CD can save hours of download time.
 
XP File and Settings transfer Wizard 
- XP File and Settings transfer Wizard provides an easy transfer from your old Windows to your new
 
Using clri to reset an inode problem 
- This is an interesting post about someone who had a directory entry pointing at an unallocated inode. Usually those things get fixed by the system itself when it reboots, but somehow this one didn't. Or maybe it just wasn't rebooted.
 
Using File and Settings Transfer Wizard as Windows backup 
- Blog # 934 Using File and Settings Transfer Wizard asWindows backup
 
Disappointed with LDAP 
- I thought LDAP would really be helpful, but of course Microsoft has to muck it up as they always do.
 
Roaming wireless access, spam 
- It looks like it's getting closer: internet access as easy and ubiquitous as cell phone access. I'm all for that, but it also probably means thousands more insecure, unprotected machines, which means even more spam for the rest of us.
 
Shameful Internet providers 
- ISP's should have some responsibility to warn their customers before blindly connecting to the Internet.
 
Misunderstanding partitions and divisions 
- Misunderstanding partitions and divisions. Linux systems usually break hard drives up into multiple FDISK partitions, each of which will be a file system, SCO does it quite differently.
 
Google newsgroup links made easier 
- Google News is a convenient way to refer to News posts. If you are reading News with something else, you don't have to wait for the post to be archived by Google to create a reference; simply construct it as shown here, and when Google gets to it, your link will work.
 
How did it all happen?  by BigDumbDinosaur
- 1wsuit war being conducted by SCO Group against IBM, Linux, et al, is shaping up to be a watershed event in the history of modern computing
 
Lurker email archiver/list manager 
- database for email. But why bother with this when Gmail already does it better?
 
Understanding Debian packages  by Drag Sidious
- Debs are a "ar" archive, with 2 tarballs inside them and debian-binary text file to identify which generation of deb file it is (I am supposing).
 
Visualizing numbers 
- Some useful visualations of numbers that pass by our eyes almost every day.
 
Keep tabs on security issues with Linux easily  by Drag Sidious
- The website Linuxsecurity.com keeps up to date on the lastest security advisories issued by most major Linux distributions, as well as FreeBSD, NetBSD, and OpenBSD.
 
Replacing hard drive 
- This poster wants to replace a SCO OSR5 secondary scsi drive with a larger version
 
Unix time, UTC, TAI and all that. 
- People have this funny idea that time measurements should be reliable: 24 hours in a day, 365 days in a year, and so on. Of course the physical universe doesn't work that way: a year is slightly more than 365 days, a day is every so slightly longer than the number of seconds in 24 hours, so we need to adjust things now and then. A second is defined by Cesium radiation decay and that's TAI time, but if we used that for our clocks, we'd get slippage, so we use UTC time, which introduces leap seconds when needed. This keeps the Sun overhead at high noon, but is more than a small problem for computers.
 
Creating ext3 file systems 
- The ext3 filesystem is a journaled file system that is compatible with ext2 (an ext3 filesystem can be mounted as ext2 if necessary). It's faster and more reliable than ext2, and therefore has become popular (though so has Reiserfs).
 
Your opinion wanted 
- Web based telnet/ssh: is that preferable to command line?1
 
Maybe it's Bill's fault 
- Is interest in Computer Science inversely tied to Microsoft's success? Maybe so.
 
Slashdot subscriptions??? 
- It will surprise me greatly if very many people are willing to pay money to read SlashDot.
 
Creating Cool Web Sites 
- I think the one thing that impressed me the most about this book was that the author didn't mention FrontPage or any other Web creation tool. He didn't even mention using Word, other than as a cautionary "Don't". No, he suggests Notepad, Mac TextEdit, or vi, pico etc. That alone is so refreshing.
 
How Linux Works 
- Subtitled "What every superuser should know", this is a good techie overview of Linux. This is not the book you hand to Grandma (unless Grandma is a system admin), but it is a very well done Linux guide/introduction.
 
perl 
- A powerful scripting language very popular in the Unix world, probably because anyone familiar with Unix tools like awk and sed can quickly make use of Perl's much more powerful abilities.
 
scponly 
- A restricted shell for specific use with scp and sftp. It is configurable, o you can add or subtract apps it can use, but the base purpose is to provide security for file transfers. Often used in conjunction with chroot for even greater lockdown.
 
Visicalc 
- The grand-daddy of spreadsheets, and still available today in its original glory: VisiCalc Executable for the IBM PC. Another early spreadsheet was Multiplan, which realy was quite advanced for its day, offering linked sheets and other powerful features.
 
CVS 
- Concurrent Versions Systems. The general standard for version control. Allows multiple people to work on a project by tracking changes and controlling access. Primarily used for code, but there's no reason it can't be used for any project where multiple people modify files.
 
Bogon 
- A Bogon address is an ip address that shouldn't be in a routing table and therefore shouldn't be used for hosts or devices. These are not the just the reserved private addresses we use for internal networks. Bogon addresses are often used as the source addresses of DDoS packets.
 
kit 
- A set of recompiled programs that hide the activities of someone who has hacked and taken over your system. The programs would include such things s 'ps', 'netstat', 'who', etc. on Unix systems and their analogs on Windows.
 
POTS 
- Plain Old Telephone Service. This acronym has been in use for quite a while, almost before there really was much else other than plain old telephone service. POTS is circuit based, and of course the newer concept is packets.
 
interface 
- This is an interface that leaves open views open. If applied to a web browser, it would mean that every link you clicked on would get a new window. Most folks wouldn't like that, but the designers of some file system interfaces, notable Gnome, insist that is how file system navigation should work.
 
rpc 
- Remote Procedure Call. The concept here is that a program on one computer can use a service on another computer without being bothered with the details of network communication. The 'rpcinfo' program can tell you what rpc services are available on a server;
 
Wix 
- Microsoft's open source Windows Installer XML project. Huh? Microsoft embracing open source? Well, do note that this is something that creates Microsoft setup packages, so there's little altruism here.
 
Syslogd MARK option 
- I've had people worried by their seeing MARK in logs and not knowing why it was there, but until this thread I'd never seen anyone wondering why it WASN'T there.
 
HIPAA Security Rule gap analysis  by Michael Desrosiers
- HIPAA is arguably the most challenging issue facing healthcare organizations today. The Security Rule provisions of HIPAA are now at the forefront of healthcare legislation in the United States, and all healthcare providers will be held accountable for compliance. These measures, although cost intrusive and time consuming, will ultimately result in cost savings and increased efficiencies across the entire healthcare industry.
 
Using exclude with "du" 
- This comp.os.linux.misc poster wanted to exclude multiple directories from "du"'s totals. Answers pointed out that he could put the list the files to exclude in another file and use -X filename. Wildcard patterns are allowed in this file, and also can be used with --exclude (quote wildcards):
 
Bash shell $PIPESTATUS 
- PIPESTATUS array holds the exit status of your last foreground pipeline commands.
 
Google's Gmail 
- Why is this so good? The problem all heavy email users have is organizing and searching our mail.
