Help with pv?
by Kevin McGregor 16 Dec '14

16 Dec '14

I have two identical Unix servers (Oracle T5-2, Solaris 11.2) and I want to do some testing of the network redundancy/failover I've configured (which I hope I've done right). Each server has four network ports. Two ports on server 1 and two ports on server 2 are connected to switch 1. Two ports on server 1 and two ports on server 2 are connected to switch 2. I want to do something like this: root@srv1:~# pv </dev/zero | ssh root@srv2 'cat >/dev/null' and get a running throughput rate while I unplug and replug cables, BUT I'd like to have four simultaneous streams and four running totals. I don't know how to do this. I'd rather not have four separate sessions open to see this. I just want to have one session that looks like 448MB 0:00:09 [ 112MB/s] [ <=> ] 448MB 0:00:09 [ 112MB/s] [ <=> ] 448MB 0:00:09 [ 112MB/s] [ <=> ] 448MB 0:00:09 [ 112MB/s] [ <=> ] Or similar. Any suggestions?

Another Solaris configuration issue - xterm
by Kevin McGregor 16 Dec '14

16 Dec '14

I'm using Solaris 11.2 on a T5-2 SPARC server, and when I log in on the console (via ILOM, using PuTTY), the terminal type gets set to "sun", which is really annoying. I've tried svccfg -s system/console-login setprop ttymon/terminal_type=xterm (followed by a reboot) and editing the /etc/profile line from TERM=sun to TERM=xterm and still the TERM variable is "sun" when I log in. What else can I try?

tock.umanitoba.ca NTP over IPv6 broken?

Hi Guys: Wondering if tock.umanitoba.ca works for anyone via IPv6? I'm able to ping the system, but NTP gets stuck in INIT state.

Fix for yum "Error: database disk image is malformed"
by Gilbert E. Detillieux 11 Dec '14

11 Dec '14

On one of my RHEL 6 compatible systems, I ran out of space on /var, and after clearing space, yum kept throwing the above error message. After doing a Google search on the error, various suggestions were tried... 1. "yum clean all" (and variations on that to clear certain parts of the cache) didn't fix the problem. 2. "yum history new" also didn't help. 3. "rpm --rebuilddb" also didn't help. Finally, after finding this posting... http://linux.upubuntu.com/2012/04/yum-error-database-disk-image-is.html ... and looking at the bottom of the comment section, I found this command... 4. "yum makecache" did the trick! Here I thought that running a "yum update" after "yum clean dbcache" or "yum clean all" would rebuild everything it needed, but apparently not. So, it's good to know that "yum makecache" will do a more thorough rebuild of the metadata. Hope this is useful to any of you running yum/rpm-based distros! -- Gilbert E.

MUUG Meeting, Dec 9, 7:30pm -- Real-Time Mapping with *ouchDB
by Gilbert E. Detillieux 02 Dec '14

02 Dec '14

The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, November 18. The meeting topic for this month is as follows: Mingling and Pot Luck As 2014 draws to a close, MUUG has decided to continue our new tradition of turning the December meeting into more of a social event. This will be a totally pot-luck event. Cookies and pop will be provided by MUUG, but members are encouraged to bring their own food to sample and share. Feel free to bring your own drink as well if you want something particular - just remember that we don't have a liquor license! Real-Time Mapping with *ouchDB (CouchDB/PouchDB) After the mingling and munching, Robert Keizer will be presenting how he set up a very simple real-time map using an Android phone and some JavaScript. The talk will focus on separating the data layers and some of the nice features in *ouchDB. Winnipeg Harvest Food Drive Also as in previous years, we are combining our pot luck with a food drive for Winnipeg Harvest. We would love it if each member would bring at least 1 non-perishable food item for donation to the food bank! Winnipeg Harvest has apparently been running a shortfall all year, and needs your donations, particularly at this time of year! They have information about what they're looking for on their website: http://winnipegharvest.org/donate-food/ 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 *NEW* meeting location for this month: Room 1L08, Lockhart Hall, University of Winnipeg, entrance on Ellice Ave. between Spence St. and Balmoral St. Parking is available on the surrounding streets and in the lots on nearby streets. Look for signage once you're at the building, or ask a security guard. ***************************************************************** 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.

weird cert problem
by Trevor Cordes 01 Dec '14

01 Dec '14

Does anyone else get a cert error on this site: https://taxcess.gov.mb.ca/ It's invalid in Firefox (latest F19 version: 33.1, just came out today) on Linux. But it works ok on Chrome in Windows. Chrome shows the cert is brand new this month (I had never had a problem with their site before). Weird that a trust-validated site like that would have cert problems, unless they chose a no-name CA? Unless someone is MitM'ing me...

My Thinkpad A31p has served me well as a portable workstation. I have install AntiX Linux (lightweight distro) which works, but is too slow. Not the fault of the distro, but the Thinkpad is limited by amount of ram that can be used. Looking to replace with a current or used workstation grade laptop.

Using Opera, the site gives a message: The certificate for "Entrust Certification Authority - L1K" is signed by the unknown Certificate Authority "Entrust Root Certification Authority - G2". It is not possible to verify that this is a valid certificate.

[Muug] MUUG Meeting, Nov 18, 7:30pm -- LiveCode
by Gilbert E. Detillieux 10 Nov '14

10 Nov '14

The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, November 18. The meeting topic for this month is as follows: LiveCode This month, Brad Vokey will give a demonstration of LiveCode: an open source, cross-platform, rapid application development language. LiveCode evolved from MetaCard (the original Unix HyperCard clone) into becoming a true cross-platform IDE capable of running on iOS, Android, OS X, Windows, and several variations of Unix including Linux, Solaris, and BSD. It can be used to write mobile, desktop and server/CGI applications and is the most widely used HyperCard/HyperTalk clone. LiveCode uses a high level, English-like programming language that is dynamically typed and tightly integrated to your program's interface. The language and compile-free work flow generate code that is self-documenting and very easy for casual programmers to comprehend. As this month's RTFM topic, Wyatt Zacharias will compare and contrast the curl(1) and wget(1) commands. Please note change in meeting date for this month. This month's meeting is also the Annual General Meeting, where we will have an election (most likely by acclamation) for the new MUUG board of directors for the 2014-2015 year. 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 *NEW* meeting location for this month: Room 1L08, Lockhart Hall, University of Winnipeg, entrance on Ellice Ave. between Spence St. and Balmoral St. Parking is available on the surrounding streets and in the lots on nearby streets.
