can't find tty in protected database -->Re Long Pause During Login  by (various authors)
- Check the permissions on /etc/resolv.conf. It should be 644 and not 640. Telnetd insists on doing a reverse DNS lookup on literally every connection (including local) and requires a DNS server. You can speed things up if the DNS server goes down by putting bogus entries for each of your remote machines in /etc/hosts for each of your pseudo ttys. The host names don't need to be real or even sane.
 
linux out of vm virtual memory -->Re VM Killing process....  by (various authors)
- To survive this, the kernel goes into lifesaver mode and begins "reaping" processes somewhat randomly in order to free memory so that it won't crash. (I think the only process safe from reaping is probably init).
 
apm advanced power managent shutdown power off -->ReShutdown Help ME please!!!!!!!!!  by (various authors)
- Make sure you have enabled Advanced Power Management with mkdev apm. Then, edit the file: /etc/conf/pack.d/uapm/space.c The file is self-documenting. Towards the end of the file, there is a data structure that lets you specify the power state to enter during various shutdown events. Change the line for a normal shutdown to power down the system. Relink the kernel and try a sync; haltsys from single-user mode for a quick test of the power-down feature. Not all motherboards support APM properly, and some systems may work with 5.0.5 but not 5.0.6.
 
ctrl-alt-delete reboot -->Re Disableinghalt/reboot/poweroff  by (various authors)
- Absolutely right. I can't really lock the computer case in a safe box (that would be the only near 100% perfect solution to the problem), but I'm applying all the basic security measures, like password protect the BIOS setup, allow only the harddisk to boot, remove the lilo prompt, disabling CTRL-ALT-DEL and the halt command...

Network ftp speed  by (various authors)
- To use the table, find the number 1 in the column of the unit you want to convert (eg, kybtes - "1" is 4th down) then multiply by the numbers in the SAME row that correspond to the target unit (column) you require. So to convert kbytes to bits, multiple by 8196. To convert megabytes to kbytes, multiply by 1024, etc.

tcp connections pseudo ttys NSTRPAGES -->Re No more than230 TCP connections.  by (various authors)
- You need to run `netconfig`, click on "SCO TCP/IP" below your NIC (not the one below "Loopback driver"). Then go to [Protocol -> Modify protocol configuration] and raise the number of TCP connections. You can also raise the number of pseudo ttys here. These thing scost a bit of memory, but not terribly much. Try setting TCP connections to 1024, pseudo ttys to 512.

No exessive LAN traffic if printers with one model of JetDirect card ran out of printer and HPNP would poll the printer thousands of times per second?
 
xenix  by (various authors)
- Just to point out for those unfamiliar with Xenix, the OS itself is actually under 50, heck, under 10!. An entire Xenix filesystem can not even exceed 512M, though you can have multiple 512M fs's mounted for a total system that exceeds 512M.

gunzip File Size Limit Exceeded (core dumped)  by (various authors)
- The size of an individual file is limited to 2GB in OpenServer. Presumably you mean that the unzipped size is ~5GB and the zipped size is smaller? The amount of data that can flow through a pipe is not limited to 2GB. (But it will still fail if any individual file stored in the tar archive is larger than 2GB.)
 
file system fragmentation defragmentation linux -->Re Defrag in linux? - Newbie question  by (various authors)
- In a single-user, single-tasking OS, it's best to keep all blocks for a file together, because _most_ of the disk accesses over a given period of time will be against a single file. In this scenario, the read-write heads of your HD advance sequentially through the hard disk. In the same sort of system, if your file is fragmented, the read-write heads jump all over the place, adding seek time to the hard disk access time.

- Values over 128 represent the OR'ing of 128 with a signal that killed tar (or any other program). SIGINT = 2; 128 + 2 = 130; SIGTERM = 15 ... Skimming the tar source turns up these exit codes:
 
add cr/lf carriage return line feed crlf -->Re ADD CR/LFTO FILE  by (various authors)
- Well, your little program is not what he needs, because the file he has to work with has NO NEWLINES in the first place, so I suspect your addcr/rmcr would not do what he wants, which is to add a NL/CR after every 2048 bytes in the input.
 
corrupt header This does not look like a tar archive skipping to next header archive contains obsolescent base-64 headers  by (various authors)
- Tar files can be damaged. This Perl script can fix some corrupt tar archives and recover data.
 
linux save restore mbr master boot record lilo -->Savin gand Restoring an MBR  by (various authors)
- Using DOS debug to read MBR record in an emergency: You should make a backup copy of your MBR on a bootable floppy disk before installing Linux and then again after installing Linux.
 
linux shmmax -->Re How to modify the value ofSHMMAX?  by (various authors)
- linux shmmax -->Re: How to modify the value ofSHMMAX?
 
wiring for apc ups cables smart ups uninterruptible powersupply -->APC UPS Cable wiring  by (various authors)
- It's another day in UPS hell. For the zillionth time, I find yet
 
Why should you use Linux 
- When I find myself doing repetitive tasks, I automate them through scripting. Scripting a GUI is possible, but much more difficult and usually less powerful.
 
Linux sucks, windows is better than linux 
- OK, we've all heard it: Linux is too hard, Linux sucks, Windows is easier than Linux, yadda, yadda.
 
Ksh exported functions shell scripting 
- Most shells support "exported functions". Understanding how to make functions available to other scripts can be confusing.
 
New Samba exploit 
- This could allow someone who had gained internal access through hacking a non-admin account to escalate their privilege and get root access to the Samba server.
 
SCO Blames losses on competitive pressures 
- SCO blamed the revenue decrease on competitive pressures and a major drop in the company's effort to license its Unix intellectual property. Ayup. I'm sure it had nothing to do with that stupid lawsuit.
 
Dvorak: Tech Words of the Day 
- No, not John Dvorak the columnist, but Dr. August Dvorak, the inventor of the DSK (Dvorak Simplified Keyboard). Dvorak was actually following up on work by Frank Gilbreth, author of Cheaper by the Dozen.
 
Archie: Tech Words of the Day 
- If you search around for definitions of Archie, you'll find out that it is a tool for searching for files from anonymous ftp servers. You'll probably also find comments like this: 'Back when FTP was the main way people moved files over the Internet archie was quite popular.' I would certainly agree with that - I haven't used archie in a long, long time. And yet, a Google search will turn up lots of Archie servers.
 
Importance of home firewalls 
- I've said this before: it is unconsciable that DSL and Cable providers allow home connections without firewalls. The referenced article details the results of this foolishness.
 
Are people too lazy to learn about their computers? 
- Not everyone has to be interested in computers. For some, they are a means toward other ends only. It's not that we don't have the intelligence - we may just lack the time.
 
More bad news for SCO 
- Poor SCO. The 'millions of lines' of code never turned up, but if they had, it might not matter anyway. Apparently USL had to agree a long time ago that most of it was free to redistribute. The funniest part of this link is the 'SCO declined to comment on this story'.
 
Word HTML Cleanup 
- I hate it when somebody sends me an HTML document created by Microsoft Word. It's bloated and full of unneeded markup.
 
XMPP: Tech Words of the Day 
- The formal Extensible Messaging and Presence Protocol, which came from Jabber (open source IM). The important things to know about this are that it is XML based (and thus its messages are human readable if unencrypted, and it is easy to write code to handle these) and that it is extensible: new features can be added.
 
Definitely Not an Answer to Questions about Solaris 10 
- Sun's Common Development and Distribution License (CDDL) was published this week. It's a license for.. well, that's the point: Sun isn't saying. They've offered a license, but haven't said what products it will cover.
 
Stop working so much 
- We work too much. It's not good for our health, mental and physical. Stress takes a toll on us.
 
"Robot" devices for mobility from Toyota 
- Someday, assistive devices like this will be inexpensive and versatile, heping to give real quality of life to many.
 
Xorg: Tech Words of the Day 
- Xorg replaces xfree86 for Linux gui now appears to be taking over - RedHat, IBM, Sun, Suse and Debian all are adopting it over Xfree86. While you will hear people arguing technical points, the reason behind this fork was political.
 
Some control of XP with GPEDIT.MSC 
- Blog # 1166 Some control of Windows XP Pro withGPEDIT.MSC
 
VeRO: Tech Words of the Day 
- Ebay's Verified Rights Owner's Program (gosh that's awful). The purpose of this is to allow manufacturers of products to prevent sales by unauthorized vendors. 'Naw', you protest, 'if I own it, surely I can sell it?'. Nope.
 
Howl: Tech Words of the Day 
- Mac users familiar with Rendezvous know what Howl is: its Zeroconf networking. Open source, yes.
 
CentOS - RHEL compatible distro  by Bruce Garlock
- CentOS - RHEL compatible distro. Since RHEL would not fit the bill (because of the bill), I started searching and found two capable distro's that are built on RHEL, and supported in much of the same way.
 
TLS: Tech Words of the Day 
- The open incarnation of SSL. SSL (Secure Socket Layer) was the original encryption for web sessions, TLS (Transport Layer Security) does exactly the same thing but is open source.
 
Machines will never think as well as humans 
- Human brains ARE machines. Any argument that any idiot wants to make against machines ever being capable of anything can be applied with equal validity to our own brains.
 
dmidecode: Tech Words of the Day 
- Dumps BIOS information. From http://www.nongnu.org/dmidecode/: ;Beware that DMI data have proven to be too unreliable to be blindly trusted. Dmidecode does not scan your hardware, it only reports what the BIOS told it to.'
 
RBAC: Tech Words of the Day 
- Role Based Access Control. Often part of a MAC (Mandatory Access Control) system, but can be present on a system where root still retains absolute power. Terminology varies widely with specific implementations, but there will be some set of defined privileges or authorizations that can be assigned to certain users or processes. For example, SCO OSR5 defines an authorization for backup (from the docs):
 
Internet Taxation in Germany  by BigDumbDinosaur
- the art of keeping the citizenry under the government's thumb apparently did not die in Hitler's bunker
 
Automating Unix and Linux Administration 
- This isn't a book for rank beginners; it assumes that you know a thing or two about system administration
 
More folks dumping IE 
- Penn State has told its 80,000 students to not use Microsoft Internet Explorer.
 
But I don't have an email password 
- This was prompted by a call from my sister-in-law who complained "Some of my email still goes to my old computer". Of course you and I realize that for your typical home user, email doesn't "go" anywhere at all - the computer goes out and gets it from somewhere, but it's all the same to her: some of her email is ending up on the "wrong" computer.
 
nat, masquerade: Tech Words of the Day 
- Network Address Translation. Purists like to reserve this for the specific case of one to one mapping: one internal address to one external address. That usually means that you'll have a block of public addresses, though it doesn't mean that you need a public IP for every internal address.
 
Freedom of Information 
- With regard to the large companies that dominate markets, I definitely do not see that as a good thing. Extreme concentration of capital seems to lead to abuse of all kinds, and we've talked a lot about that here: stifling of innovation, abuse of employees, government in cahoots - it isn't pretty.
 
External SATA drives 
- Will SATA drives replace SCSI? Possibly. In theory, at least, multiple SATA disks have higher throughput than multiple SCSI drives because they aren't sharing a bus until they get back to the PCI card that's driving them. There's a discussion of SATA RAID over at Tom's Hardware that covers that. SATA can also be less expensive, as http://www.tomshardware.com/storage/20030501/wd360-01.html suggests.
 
Stolen Software 
- Even churches steal software. Maybe churches even steal more than usual - with unusual and usual excuses.
 
Linux|Unix certification gaining ground but Cisco still on top 
- Blog # 1182 Linux certification gaining ground but Ciscostill on top
 
pagerank: Tech Words of the Day 
- Primarily Google Pagerank, but could refer to any generic indication of site popularity. All of us who run web sites fret over popularity
 
Goodbye, AOL 
- At one time, way back in the mists of time, I had an AOL account. I never really used it - when I signed up, I already had internet access elsewhere. I just wanted it for the odd circumstance where they might have something I needed.
 
Google to index libraries 
- The Google book indexing project, although hampered by numerous lawsuits, is still going strong.
 
Science, Math, and Technology 
- American ignorance and disdain for science doesn't bode well for our future, does it?
 
winmodem: Tech Words of the Day 
- A traditional hardware modem really is two major parts: the modulator/demodulator (hence 'modem') which translates the buzzes and hisses to bits and vice versa, and the 'personality': the hardware and software that lets you type AT commands, does error checking and all the rest.
 
Open Royalties for Book Authors 
- I suppose a lot of us think we'd like to write a book someday. Yes, I have that secret desire also, though realistically I know that I lack the discipline to focus in on one subject. My interests flit around all over the place and could never settle down long enough to grind out a whole book. That's me, just a flighty dilettante. I'd need someone with a whip standing over me to have any chance.
 
Some "Remove me" links really work 
- Techdirt reports that at least some spammers really will remove your name from their lists if you tell them to. Of course that's useless information along the order of "some lions won't maul you if you poke your finger in their eye"
 
ADOBE security screwup 
- Adobe has a really bad record for security. When they say you need an update, you are wise to do it quickly.
 
Why are in-addr.arpa addresses backwards? 
- An 'in-addr.arpa address' is a reverse DNS record, stored in a strange format. If we are considering ip 1.2.3.4, then '4.3.2.1.in-addr.arpa' is the reverse DNS record.
 
autonomic computing: Tech Words of the Day 
- I'd say it's more a matter of prejudice than a matter of definition. Just what "human cognitive powers" aren't present in "systems that can adapt, learn and take over certain functions previously performed by humans"? Are we simply talking about the degree of intelligence? If so, fine: our machines are still a long way from even approaching human intelligence. But whenever someone says something silly like "we can never model the human brain because it's too complicated and we don't understand how it works", I am immediately reminded that almost anything could have been phrased in such terms at some point in our history.
 
Microsoft enters the "Protection" racket 
- Neat idea! Even better than it looks, because now they can make the product even MORE dangerous, and sell you MORE tools to protect yourself! Suddenly it all becomes clear: this was the plan all along! These guys are brilliant.
 
"Tux" - new Linux magazine 
- "Tux" - new Linux magazine in 2004, dead after just twenty issues. That probably says more about the future of magazines than the future of Linux.
 
You "may discover" things about Microsoft 
- After you set up Windows Firewall in XP SP2, you may discover that anyone on the Internet can access resources on your computer when you use a dial-up connection.
 
Linux|Unix clusters  by Drag Sidious
- Right now I am working on my own cluster. 3 machines using the OpenSSI project. Similar concept to OpenMosix and it uses some of OpenMosix's algorythms for it's load balancing.
 
Testing for network connectivity in a script 
- Sometimes a script needs to know if it has network or internet connectivity before it continues, or perhaps its whole purpose is the report a loss of connectivity or inability to reach specific services.
 
Securing your network to specific machines 
- Securing your network to specific machines with MAC address lockdowns in iptables with the MAC module, which matches packets traveling through the firewall based on their MAC (Ethernet hardware) address
 
openMosix: Tech Words of the Day 
- OpenMosix is transparent clustering - processes migrate to other members automagically.
 
IBM: Linux Desktop Migration RedBook  by Bruce Garlock
- IBM has released a very interesting read, on migrating to desktop linux. The RedBook, contains lots of different topics for migration, and covers just about all the different areas.
 
More amazing Microsoft IE "features" 
- Do you think Microsoft will ever make a secure browser? Maybe, but it's been a long time coming. I know, I know, I'm a grump about this, but "easy" shouldn't be the primarily goal.
 
Converting SCO to Linux 
- Nothing new here, but I just thought I'd gather some links to a convenient place:
Self defense for SCO users
SCO/Linux Transition Guide
Time to dump SCO?
How can I mount a SCO file system in Linux or vice-versa?
How can I transfer SCO accounts (passwd information) to Linux?
Can Linux run OSR5 binaries?
New to SCO
 
Information about telnet sessions 
- Is there a way to identify which telnet session corresponds to which ptty? I would like to know the remote ip address and the ptty of each telnet session
 
TCB, MAC, DAC: Tech Words of the Day 
- Trusted Computing Base. The programs (more technically, objects and processess) that are trusted to do what they are supposed to do (and only what they are supposed to do).
 
cfengine: Tech Words of the Day 
- This is not something you deploy for the heck of it. Setup and preparation is complicated and may not be worth the effort if you only have a few systems.
 
Ejector for OSX  by Bruce Garlock
- This is a handy little utility for OSX. It adds an "Eject" button on the menubar, for quick access to ejecting volumes.
 
PPTP VPN, and weak passwords  by Bruce Garlock
- PPTP VPN, and weak passwords. I use a VPN to connect to work. I run a PPTP server on Linux, at my firewall, for our remote users to connect from home to our work network. As has been explained before, PPTP has had it's share of security issues.
 
Interesting thread (ls vs. ls -l) - lessons for newsgroups 
- ls vs. ls -l - Why did "ls" work but "ls -l" hung and froze? There are a lot of bad guesses and poor troubleshooting techniques to be seen in the thread.
 
Fcheck: Tech Words of the Day 
- Another IDS (intrusion detection system). Open sourced, though personally I find it a little scary that the author is hosting his website at Geocities.
 
snapshot: Tech Words of the Day 
- snapshot: A filesystem technique that allows leisurely backups while continuing to use the system. This magic is accomplished by making a special copy of a directory or filesystem (the exact mechanics will vary with the product you are using) that doesn't really copy anything unless and until data changes at the source. Here's how it works: Let's say that you have created a snapshot of some directory in /snap. If you read files in /snap, they look just like the files they were created from. Actually, you are still reading from the original data blocks at this point.
 
They're b-a-a-a-ack.. 
- SCO keeps trying and trying. What was that definition of insanity? Oh yeah: doing the same thing and expecting a different result.
 
bashdb: Tech Words of the Day 
- A better debugger for your Bash scripts: http://bashdb.sourceforge.net/. Actually, it replaces Bash, so if your script was particularly strange, you might exhibit a problem when it runs under bash
 
lftp: Tech Words of the Day 
- A very sophisticated ftp/http/sftp command line client. It's very like ncftp, but is Open Source. Its history function works like Bash (ncftp is a bit different). It has a "mirror" function and even a reverse mirror.
 
Troubleshooting: Try something different 
- Many years ago, I did some consulting work for a local weekly newspaper. They had a mixed network of Unix machines, a Novell server, and quite a few Macs. I worked mostly on the Unix side, but one morning I was asked to run down to Editorial because there was some major problem. The person doing the asking was the President, so I suppose he wasn't really asking. He looked upset.
 
arts: Tech Words of the Day 
- Analog RealTime Synthesiser. That doesn't interest me very much - I know, I know, sound is important, but not to me. Sorry.
 
Troubleshooting: Preserve the scene 
- You've seen it on television or in the movies: important evidence is lost at a crime scene because someone wasn't careful enough to preserve it. A crowd of curiousity seekers destroys important footprints, a helpful housekeeper thoughtfully washes the bathroom sink, wiping away fingerprints. The police investigators show up and are angry at the carelessness of the patrol officer who should have protected the scene. A crime scene investigator always wants to preserve and protect evidence.
 
Linux|Unix on your iPod 
- You may use this program to install linux on your Mac formatted first, second, or third generation iPod. Your iPod should have the newest apple firmware on it. DO NOT try to install this on an iPod mini, fourth generation iPod, iPod Color, or Windows formatted iPod.
 
ClusterKnoppix: Tech Words of the Day 
- More clustering. Download the cd images, follow the tutorial directions, and bingo, you have a cluster. I have a couple of semi-dead machines here that I can try this on - looks like fun!
 
Asteroid Impact Calculation 
- What actually might happen if one of those 'near miss' asteroids didm't miss us? This calculator shows you what.
 
Gambas: Tech Words of the Day 
- This has been described as 'Visual Basic for Linux'. However, as explained at http://gambas.sourceforge.net/, it is like Visual Basic, but is definitely not mean to be a clone.
 
Randal Schwartz's Perls of Wisdom 
- Randal Schwartz was co-author of the first and second editions of the Perl Camel Book> and of another of my favorites, Learning Perl
 
dns: Tech Words of the Day 
- Domain Name Service: how names like www.xyz.com are translated to ip addresses so that your packets and theirs can find one another. For many of us, DNS is simple. If we are using DHCP, we may get everything we need for DNS from the dhcp server.
 
Perl 6 Now: The Core Ideas Illustrated with Perl 5 
- Perl 6 scares me. It probably wouldn't have shaken me up so much if I hadn't read Larry Wall's State of the Onion 2003. I'm sure Larry didn't intend to frighten anyone, but he is so intense and often so obscure. He can be fun to read, too, but his expositions on Perl 6 really made me a bit nervous. I'm not alone, at least with regard to fearing Perl 6
 
Tarantella: Tech Words of the Day 
- The company formerly known as SCO. Or what was left over after Caldera bought all the Unix related stuff. Tarantella makes a product that competes with Windows Terminal Server.
 
Motivation Through Job Recognition  by Claudia Garcez
- The first and probably the best way to motivate your workers is through positive reinforcement. As a leader, you should always praise good performance. It is extremely important for your employees to feel they are doing a good job. Recognition is the way to get your employees to perform at highest level. Employees are willing to do whatever it takes to perform their best, as long as they feel their work is appreciated.
 
local security policy won't permit interactive logon 
- I found it amusing to contemplate Microsoft's "Ease of Use" here. You would think that you'd get a drop down list that you could choose Groups from when creating a user. Well, you can, but that's under the Advanced tab, which brings you to a confusing search window where it looks like most everything is greyed out. If you charge ahead on faith, you will get the list of groups you can pick from.
 
ProFTPd, wu-ftpd, and general ftp security 
- FTP in general has a long and sad history of security problems. If you need to run an ftp server, you need to keep careful track of vulnerabilites and exploits that may make for a very unhappy day. Things have gotten better in recent years, but just as I started this article I checked the wu-ftpd site and found a fairly recent problem noted, and an even more recent problem discussed at proftpd.org . Makes you want to forget ftp entirely, doesn't it?
 
Custom Tab Completion 
- I'm sure you already know about tab completion: type part of a command name and hit TAB and you get its matches. Leave a space and then hit TAB, and you get filenames. Wonderful stuff.
 
Writing and Compiling C programs on Linux 
- Writing and compiling c programs on Linux, common errors for beginners. Most Linux and Unix programs are written in C. When you download source for a project, it will often be C or C++ source code. You don't necessarily need to know a darn thing about C or anything else to compile the source if you aren't changing it. It may be helpful for you to understand a bit if you are having problems with the compile, but even that isn't really necessary.
