Helper BASH script for systemctl
by Brian Lowe 13 Feb '19

13 Feb '19

As I mentioned at tonight's meeting, I've written a helper BASH script for systemctl. Source is attached. Put it into /user/bin or /usr/local/bin (in which case you may need to add /usr/local/bin to root's PATH), and run 'sc --setup' to have it set up the symlinks. Brian

MUUG Meeting, Feb 12, 7:30pm -- Cacti, RTFM: systemctl
by Gilbert E. Detillieux 05 Feb '19

05 Feb '19

The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, February 12. The meeting topic for this month is as follows: Cacti Cacti is an open-source, web-based network monitoring and graphing tool designed as a front-end application for the data logging tool RRDtool. Cacti allows a user to poll services at predetermined intervals and graph the resulting data. Wyatt Zacharias will be giving us a new look at this software. RTFM: systemctl(1) Most Linux distros have now adopted systemd as the new init process. Gilbert Detillieux will introduce the very basics of using systemctl(1) to control services in a systemd-based environment. The group 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 meeting location for this month: *Room 1M28* Manitoba Hall, University of Winnipeg, entrance on Ellice Ave. between Spence and Balmoral St. Parking is available on the surrounding streets and in the lots on nearby streets.

MTS blocking NTP
by Trevor Cordes 27 Jan '19

27 Jan '19

I noticed that at one of the customers I have that uses low-end business MTS has had their NTP incoming/outgoing port (UDP 123) cut off (filtered) at the ISP. Incoming I can understand, but outgoing? All the computers in the office have their time out of sync now. Does anyone know what the internal Bell/MTS time server's IP/domain is? Surely they didn't cut us off to their internal one. Will have the customer contact them eventually, but you know how it goes with tech support. Looking for the quick solution... Anyone else have their UDP 123 cut off since Bell came along? Further: it looks like they are filtering outgoing only if your source port is also 123. That is hardcoded into ntp (from what I've read). But ntpdate allows the -u option to have the src port be >1024. I tried that and ntpdate -u does work, but ntpdate without the -u gets blocked. So they really are blocking in and out, but only src=123udp. Looks like chrony (and others) lets you specify src port, but I'm loathe to uproot the system I know because Bell is braindead. (MTS didn't use to block it, and block-happy Shaw does not block it.)

Jan 8 meeting - ethernet cards
by Adam Thompson 03 Jan '19

03 Jan '19

Assuming I make it to the meeting at all (here’s hoping), I expect to have four dual-port E1000 NICs to give away; two are PCI-E and two are PCI-X. Oh, and if anyone needs IDE/ATA cables, please let me know – I’ve got more here than I know what to do with, and would LOVE to send them to a good home. -Adam

MUUG Meeting, Jan 8, 7:30pm -- Test Driving oVirt with Nested KVM, RTFM: systemctl
by Gilbert E. Detilllieux 31 Dec '18

31 Dec '18

The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, January 8. The meeting topic for this month is as follows: Test Driving oVirt with Nested KVM oVirt is a KVM based virtualization solution by Red Hat which works on a data-centre / multi-server scale. Mark Jenkins will show that you don't need a rack full of servers or a SAN to try it out or simulate a production environment. The secret sauce for this is nested KVM. RTFM: systemctl(1) Most Linux distros have now adopted systemd as the new init process. Gilbert Detillieux will introduce the very basics of using systemctl(1) to control daemons in a systemd-based environment. The group 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 meeting location for this month: *Room 1M28* Manitoba Hall, University of Winnipeg, entrance on Ellice Ave. between Spence and Balmoral St. Parking is available on the surrounding streets and in the lots on nearby streets.

ifcfg style going away
by Trevor Cordes 17 Dec '18

17 Dec '18

Upgraded some boxes to Fedora 29 and after a while I came across this bit of fun: the old network-scripts ifcfg style of configuring your network interfaces is deprecated and will be removed from Fedora eventually. I checked and Ubuntu seems to have done the same (actually, they are moving faster). This means RHEL/CentOS will have this in the near future also. The new "solution" is to use NetworkManager (of course). Strike another win for the "systemd crowd", and another loss for any advanced admin running servers with moderately complex, mostly static, network setups. So we'll all have to convert our ifcfg setups to NM format, which of course won't have a 1-for-1 replacement for every option. And we'll have to then figure out how to fight NM not to do anything automatically. And we'll (for many people, but not all) be forced to have NMd running in the background always and forever, even on static setups. Oh joy. Here's some bz ranting (no, the guy isn't me, but could be!) https://bugzilla.redhat.com/show_bug.cgi?id=1643763 At least it looks like it'll be in deprecated mode in Fedora for a few versions so one is not forced to change immediately. Ubuntu users may not be so lucky. As for now, my box had the networks come up just fine as usual when I upgraded, and I don't even have the NM rpms installed at all. But the migration will have to come sooner rather than later... ifup enp5s0.4 WARN : [ifup] You are using 'ifup' script provided by 'network-scripts', which are now deprecated. WARN : [ifup] 'network-scripts' will be removed from distribution in near future. WARN : [ifup] It is advised to switch to 'NetworkManager' instead - it provides 'ifup/ifdown' scripts as well.

Disturbing things happening at the CRTC
by Kat 08 Dec '18

08 Dec '18

They are ramming though pro-corporate policy. Proper public "consultation" periods are so short as to be impossible. Now several consumer interest groups are boycotting the process and calling them out publicly. Commissioner Miner (@fanCRTCProfling) tweeted at 4:11 PM on Fri, Nov 30, 2018: .@doctorow, Interesting thing happening at the Canadian Telecom Regulator (CRTC). A first. There is a boycott from most all the major Canadian consumer and public interest groups going on.
