Bourne shell deprecated?
by Jack Bailey 28 Apr '16

28 Apr '16

Hello List, Today someone in a meeting claimed the Bourne shell is deprecated, one of the reasons being it supposedly has security issues. Well that's all news to me, and I cannot find anything online to corroborate the claim. Is this true, is it a bash vs. Bourne FUD, or something else? Thanks, Jack

Apache logs missing
by Adrian Jenzer 28 Apr '16

28 Apr '16

Hi all I just saw that I miss some log files in /var/log/httpd. There is a gap in January/February2016, no logs are available for this period. It seemed to work fine with the earlier logs as you can see. Has someone an explanation for this? It's a Centos 7.2 VM with Apache 2.4 running ownCloud only.

Re: [CentOS] Any CentOS 6 Issues on Lenovo Y700?
by Mike Mohr 28 Apr '16

28 Apr '16

Don't flame me, but I really recommend using Ubuntu on laptops. If you really want CentOS, you should go with version 7. Many new laptops won't work well with that either though. CentOS 6 only works well these days on older hardware or on virtual machines.

Or if anyone has experience with using it under CentOS 6. I assume that the WiFi could be an issue as it uses an Intel 8260 card. I want to make the correct decision.

CentOS CI Testing Prior to Releasing Packages
by Johnny Hughes 27 Apr '16

27 Apr '16

In another thread I talked about running CI testing on a packge before release. I thought I would explain that a bit more AND ask for tests, if they are needed. Prior to pushing newly released packages into the main CentOS os, updates, extras, cr, or fasttrack repositories, we run our t_functional CI test suite on the entire repo set. So if we are releasing an update, it would be against the os and updates repositories. Or if we release fasttrack package, it would be os, updates, fasttrack repositories. We also run this test suite on the final OS repository during point release upgrades. Here is information on the t_functional suite. https://wiki.centos.org/QaWiki/AutomatedTests/WritingTests/t_functional And here is where I actually run the suite prior to releasing updates: https://ci.centos.org/view/CentOS-Core/ The reason I bring this up is we will accept updates to the tests to check for things that should be tested prior to release of a repository. If you know of something that we sometimes get wrong and create a test that returns exit code other than 0 for a fail, and if you can convince us (on the CentOS-Devel mailing list) that it should be included, then you can help us release better updates to CentOS Linux. Thanks, Johnny Hughes

where, if at all, is my virtual printer output?
by Michael Hennebry 27 Apr '16

27 Apr '16

I recently installed the package that allows having virtual printers under CUPS. I used the localhost:631 GUI to add a virtual pdf printer. I do not remember what I did. Now there are two virtual printers, one named Cups-PDF and the one I named pdfprinter. I cannot find the output from either. I do not know how to ask them. >From firefox, print to file still works, but does not do what I want. Even if it did, I'd still want to know what's going on with my virtual printers. >From an error log: Unable to create avahi client: Resource temporarily unavailable" -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards

But, since there seem to be several forks of Bourne shell, currently, is there a reference for the differences between them? > As far as I can see, this was related to "mailx" and not to the shell. I looked for substantiation of the original claim that the bourne shell had security problems. Apparently I should have looked closer. Thanks for catching that.

Semi-OT: very weird vi behaviour
by m.roth＠5-cent.us 27 Apr '16

27 Apr '16

This is weird. As in, *deeply* weird. I ssh as root from one box to another (there are keys involved), and I go to vi a file, such as # line 1 # # line 2 # # line 3 # line 4 And what I see in vi is # line 3 # line 4 BUT, if I scroll the cursor over each line with the arrow key... I see all four lines. I've also looked at another file, and same thing. Just checked it out on the server I ssh'd in from, and no problem. And now, I just ssh'd in from another windows, same way... and the weirdness isn't there. Anyone have any clues as to what's going on with that one session? mark file

The open 'Net only came in in the nineties - so security wasn't broken and insecure, back then there was physical security and careful selection as to who was allowed on, at all. mark

I remember something I'd done which used, IIRC, $UID, without realizing it was a bashism, instead of using id -u. I'll also note that all *production* scripts were once required to be bourne, but by the mid-ninties, management was starting to mandate that they be Korn shell, instead, for many reasons - capabilities, etc. Bash - I don't think I saw that till I started running RH 5.1, I think it was, about 18 years ago.... mark
