Why does so much of Unix and Linux have to be hard?   2013 07

Simple outgoing email for SCO Unix (and Linux)   2012 02  2013/05/22 rblake
- Configuring MMDF or Sendmail on SCO Unix was never fun and it only gets worse as fewer people care about any of it. Here is a simple fix for scripted outgoing email -
Local printing in Synchronics   2011 11  2012/03/06 anonymous

- Keeping an old SCO system running is sometimes necessary. Here is some help -
SCO Unix OSR5 DHCP   2011 05 
- Early SCO Unix had no DHCP capability (it did have DHCP server). That perhaps was somewhat reasonable; these machines were servers and could be expected to have a static IP address. However, as DHCP can do much more than simply provide an IP address, having DHCP would have been advantageous at times. -
Why does fsck need a scratch file?   2011 04  2011/06/02 KenPorter
- Although fsck hasn't needed scratch files for a while, large disks are reopening that need. -

Converting SCO to Linux - Another one down, two left   2011 04  2013/10/11 BigDumbDinosaur
- Our efforts to get clients off OSR5 and on to Linux commenced in earnest in 2004, which was right after SCO started with their "Linux stole our code" lawsuits. -
A SCO Openserver to Red Hat Linux Conversion   2011 04  2011/04/02 TonyLawrence
- A detailed history of a SCO to Linux Conversion - including desktop users. -
Environment variables - maximum size of a variable?   2011 03 
- An 18 MB or larger variable is much more than any shell script is likely to need, but it shows that you need not fear assigning large chunks of data -
What does a leading colon (:) mean in a script?   2010 03 
- Bash and sh both use colons (":") in more than one context. You'll see it used as a separator ($PATH, for example), as a modifier (${n:="foo"}) and as a null operator ("while :"). -
Hylafax on Centos Scripts   2010 03 
- Aside from transferring user accounts, printers, and so on, my work was just to convert Vsifax scripts to Hylafax. Those scripts were called by the application program to do such things as fax a Purchase Order to a vendor. The programming is simple enough: you find and extract the fax number and pass that all off to Hylafax. For purposes of logging and error control, we also wanted to identify the vendor name, which required adding that name to the logs that Hylafax keeps or maintaining a separate index of names to faxes queued. -
Disaster Averted   2010 03 
- He said it wouldn't shut off. I was a bit surprised that he was unaware of servers with power buttons that have to be held in for a bit to avoid accidental shutdown. -

- SCO 5.0.7v on VMware for those who cannot switch to Linux because of SCO apps that are critical. -
Unix and Linux startup scripts, Part 1   2009 12 
- In the beginning, there was "init". If you had a Unix system, you had "init" and it was almost certainly process id 1. -
Unix and Linux startup scripts, Part 2   2009 12  2009/12/11 TonyLawrence
- The rc.d system is used on NetBSD, FreeBSD and DragonFly (andpossibly a few other systems) to launch daemon processes when the system goes multiuser. -
Unix and Linux startup scripts, Part 3   2009 12 
- We have looked at both System V and BSD methods; until fairly recently that would hav e been the end of the discussion. -
Hylafax 6 on Centos 5   2009 11  2010/01/25 bubba
- I'm doing another SCO to Linux conversion and this one used Vsifax. That's hardly a show stopper, but this customer wanted to use Centos and Vsifax says they don't currently support using Centos. So we tried Hylafax. -

Facetwin logs wrong ownership   2009 09

HP makes me grumpy   2009 09 
- SCO's suggested fix is to edit /etc/conf/sdevice.d/hpasm, change the 'Y' to 'N', relink and reboot. Of course that isn't a fix: it just disables hpasm. -

Zombie SCO   2009 03  2011/09/01 TonyLawrence

Another Filepro Conversion   2008 11  2011/04/29 TonyLawrence

SCO Openserver 6 hang on crontab init 6   2008 10

Bad day all around   2008 08 
- A bad day: I've been having some strange problems with my Mac Book Pro lately. Nothing very serious; it just doesn't always go to sleep when I tell it to. The screen goes blank, and the little "sleep" light comes on, but it doesn't blink, and the hard drive and fans are still running. Sometimes it will complete the transition after a few minutes, but often I've come back after hours to find it still halfway there. -
Why use that primitive Vi?   2008 05
