SCO cron hangs "Cannot create temporary file"
by John Lange 08 May '09

08 May '09

Being the only "*nix" person in our office, I've been designated to fix a problem on a old SCO server. I know what you're thinking because I thought the same thing; "it's a dream come true!" but I didn't let my enthusiasm show. The problem is that cron was "hanging" in the middle of the night roughly every second day. The log show that it was throwing an error: "Cannot create temporary file" around 4:30am every second day, but the exact time and process running isn't always the same. /tmp and /usr/tmp are normal looking and there should be enough free disk space so that isn't the problem. Thinking that maybe something was suddenly chewing up disk and then being cleared I setup a little cron to log disk usage every 15 minutes. Now cron hangs _every day_ at about 16:30! In order to restart cron, its FIFO pipe file has to be deleted and the box rebooted. Again, disk usage is not a problem. Anyone know anything about how SCO cron works? -- John Lange http://www.johnlange.ca

CLL article in the newsletter
by Mike Pfaiffer 06 May '09

06 May '09

I was actually intending to respond earlier but my monitor kind of died over the last couple of days. I've managed to set up another one so I'm good for a while now... :-) The article was precise and to the point. We do community outreach to help people who have been left behind by the "digital revolution". The goal is to provide /minimal/ training so people are able to use computers. After the course mentioned in the article, the students are entitled to an older computer (so as not to affect sales at retail stores). We have a fair number of computers coming back for repair of hardware and software. We could use a volunteer (maybe more later) to help with these machines. We currently have five machines waiting repair as well as a "lame duck" pile which needs a bit more time. If we can catch up we should have time for other projects. Apart from classes, we're only there one day per week. At this point almost all the computers loaned out are Windows 2000 machines. However we have had requests for Linux machines and Macs. We treat them as special single unit requests. The folks in charge are reluctant to encourage anything non-Microsoft for a couple of reasons. All the folks in the Selkirk office (with one exception) only know Microsoft. They are worried about supporting something they aren't familiar with. Finally some students want to use the machines to get work and some employers want employees who *only use Microsoft*. This sort of relates to the MUUG for a few reasons. 1) All our tools are *NIX based 2) We have the special requests I mentioned earlier 3) After three returns due to virus infections the student is either dropped or offered a Linux box 4) We don't know how students will react to Linux machines (we've only had one Linux return because the student bought a new computer). The folks in charge are really excited about being approached by the MUUG. They are hoping things will develop further. You'll recognise the people from the Winnipeg lab. Three of us are already members of the MUUG and two others show up occasionally. If things work out we should all be at the next meeting on Tuesday. Later Mike

MUUG Meeting, May 12, 7:30pm -- VirtualBox
by gedetil＠cs.umanitoba.ca 05 May '09

05 May '09

The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, May 12. The meeting topic for this month is as follows: VirtualBox - Run Several Virtual Systems On A Single Host Computer Sun's xVM VirtualBox offers full virtualization on many host platforms for many guest systems like Linux, Windows, BSD, OpenSolaris and many others. VirtualBox requires no changes in the guest systems and provides for guests as far back as MS-DOS and forward to Windows Vista and OpenSolaris. In this presentation, Daryl Fonseca-Holt, from the University of Manitoba, will explain what kind of virtualization VirtualBox offers, the major features it has, and some of the uses it can be put to. During the demo, Daryl will show how to set up for a new guest in VirtualBox, install the guest, and show the effect Guest Add-ins have on the user experience of the guest system. The group holds its general meetings at 7:30pm on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend. ********************************************************************** Please note our meeting location: The IBM offices, at 400 Ellice Ave. (between Edmonton and Kennedy). When you arrive, you will have to sign in at the reception desk, and then wait for someone to take you (in groups) to the meeting room. Please try to arrive by about 7:15pm, so the meeting can start promptly at 7:30pm. Don't be late, or you may not get in. (But don't come too early either, since security may not be there to let you in before 7:15 or so.) Non-members may be required to show photo ID at the security desk. Limited parking is available for free on the street, either on Ellice Ave. or on some of the intersecting streets. Indoor parking is also available nearby, at Portage Place, for $5.00 for the evening. Bicycle parking is available in a bike rack under video surveillance located behind the building on Webb Place. ********************************************************************** For more information about MUUG, and its monthly meetings, check out their Web server: http://www.muug.mb.ca/ Help us promote this month's meeting, by putting this poster up on your workplace bulletin board or other suitable public message board: http://www.muug.mb.ca/meetings/MUUGmeeting.pdf -- Gilbert E.

Linux to SCO telnet?
by John Lange 05 May '09

05 May '09

Does anyone have a quick way to make Linux telnet work with SCO? Apparently SCO uses something called SCOANSI? Mostly it seems to be compatible but any of the SCO menu driven stuff is unreadable and backspace is broken. -- John Lange http://www.johnlange.ca
