MUUG.ca mirrors down
by Trevor Cordes 04 Nov '17

04 Nov '17

FYI, MUUG.ca had a catastrophic disk failure that led to a pathological situation causing loss of the mirror array. The mirror data will likely be unavailable for a few days. The web site and mailing lists and other services should continue to function perfectly. We'll renotify here when the mirrors are back up. Thanks for your patience!

Hello MUUG! We are a small MSP in Winnipeg, we have a few customers with Linux servers and I don't have any Linux expertise on-staff. Would like to hire someone for a ½ day or so to check a few things on the servers, maybe re-configure. Can some contact me? Thank you! Mike Z.

Small router box
by Kevin McGregor 20 Oct '17

20 Oct '17

Hey all, Maybe someone can remember the device I'm trying to recall. It's from a company that makes small devices which can run Linux and they come either as a bare board or in a small metal box with some number of ethernet ports. It's not ARM-based. I know that's vague, but surely some of you can come up with a list which will contain the one I'm trying to remember! Or something comparable, at least. Oh, and they used to advertise in Linux Journal. I'm not sure if they're still in business.

FYI: MUUG now provides a MacPorts mirror.

Unix command line challenge!
by Kevin McGregor 13 Oct '17

13 Oct '17

Given a gzipped cpio archive (12 GB!) with files in it like: wwdsvdccb101/root/data/ccb/ccbx/splapp/servers/myserver/tmp/.appmergegen_1347913274622/SPLWeb.ear/h7y1ba/data/xml/CILICEXP.xml wwdsvdccb101/root/data/ccb/ccbx/splapp/servers/myserver/tmp/.appmergegen_1347913274622/SPLWeb.ear/h7y1ba/data/xml/CILTSVTP.xml wwdsvdccb101/root/data/ccb/ccbx/splapp/servers/myserver/tmp/.appmergegen_1347913274622/SPLWeb.ear/h7y1ba/data/xml/C1LOOUPP.xml wwdsvdccb101/root/data/ccb/ccbx/splapp/servers/myserver/tmp/.appmergegen_1347913274622/SPLWeb.ear/h7y1ba/data/xml/CILTTRAL.xml wwdsvdccb101/root/data/ccb/ccbx/splapp/servers/myserver/tmp/.appmergegen_1347913274622/SPLWeb.ear/h7y1ba/data/xml/CILCSSPL.xml wwdsvdccb101/root/data/ccb/ccbx/splapp/servers/myserver/tmp/.appmergegen_1347913274622/SPLWeb.ear/h7y1ba/data/xml/CILTCLGP.xml How can I change the first component of the path to something else without unpacking the entire archive to disk first? Obviously I'll still have to un-gzip and de-cpio the whole 12GB while processing; I just don't want to put the whole thing on disk while I'm changing the path. Any ideas? Kevin

MUUG Meeting, Oct. 10, 7:30pm -- Kid3, VLAN Theory and Implementation
by Gilbert E. Detillieux 10 Oct '17

10 Oct '17

*** Please note the updated meeting location below *** The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, October 10. The meeting topic for this month is as follows: VLAN Theory and Implementation VLANs (Virtual Local Area Networks) allow you to partition a physical network at the data link layer, "creating the appearance and functionality of network traffic that is physically on a single network but acts as if it is split between separate networks." (Wikipedia) VLAN tagging (IEEE 802.1Q) allows traffic from multiple VLANs to travel between Ethernet switches over the same physical link. In this presentation, Gilbert Detillieux will introduce some of the basic concepts of VLAN setup, and show you how this can be implemented. Examples of implementation will be given using Cisco IOS commands and typical Linux network interface configuration. RTFM: Kid3 This month, Wyatt Zacharias will present and demonstrate Kid3, the KDE ID3 tag editor. The group usually holds its 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 1C16A* Centennial 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.

Looking for some AWK magic
by Wyatt Zacharias 24 Sep '17

24 Sep '17

So I've got a storage appliance that I'm trying to generate a growth chart on, but the output format of the statistics is not in a usable format. The output looks like this, with each day of the week in a column, and then 6 rows of data underneath, and then it repeats. -2- -3- -4- -5- -6- -7- -8- 5827.1 6865.6 3551.2 4649.5 4006.6 15803.5 10305.0 199.4 353.4 175.9 200.7 172.5 584.0 554.2 9.9x 4.4x 6.4x 5.9x 6.3x 5.6x 5.3x 3.0x 4.4x 3.2x 3.9x 3.7x 4.9x 3.5x 29.2x 19.4x 20.2x 23.2x 23.2x 27.1x 18.6x 96.6 94.9 95.0 95.7 95.7 96.3 94.6 -23- -24- -25- -26- -27- -28- -29- 2798.2 2235.3 2357.9 4701.3 9074.3 13796.5 11705.7 86.7 74.1 131.6 178.1 449.3 483.5 473.7 11.4x 12.0x 7.0x 8.1x 3.9x 6.3x 6.7x 2.8x 2.5x 2.6x 3.2x 5.2x 4.6x 3.7x 32.3x 30.2x 17.9x 26.4x 20.2x 28.5x 24.7x 96.9 96.7 94.4 96.2 95.0 96.5 96.0 -30- -31- -1- -2- -3- -4- -5- 2798.6 2274.5 2325.8 2472.1 2526.0 13955.3 11224.2 86.7 88.9 145.2 115.2 105.6 497.9 432.4 10.8x 10.1x 7.4x 8.1x 9.8x 6.2x 6.9x 3.0x 2.5x 2.2x 2.7x 2.4x 4.5x 3.8x 32.3x 25.6x 16.0x 21.5x 23.9x 28.0x 26.0x 96.9 96.1 93.8 95.3 95.8 96.4 96.1 Is there a way I can get awk to process 6 rows of each column at a time? -- Wyatt Zacharias

On the other hand awk has 1. a variable NR the contains the current line number 2. a % operator that can be used to compute modulo 7 3. a getline command that reads the next line of input That's all you need.

an MIT operating systems course on Github
by Grigory Shamov 14 Sep '17

14 Sep '17

Hi, It might be not that new, but just in case. In the Login magazine I won at last meeting¹s raffle there is an article about the subj. The course is opensourced. https://github.com/teachbsd/course Relies on a rather expensive book though, ³The Design and Implementation of the FreeBSD Operating System². -- Grigory Shamov WestGrid Site Lead / HPC Specialist University of Manitoba E2-588 EITC Building, (204) 474-9625
