Linux "write"
by Trevor Cordes 07 Jul '17

07 Jul '17

Can someone else confirm this bug on another Linux system, preferably a modern one that uses systemd? In X, as non-root: open a term (call it term1) open another term (term2) type "tty" in term2, not your tty number/string in term1: type "write <your-login> <tty-string-from-above>" replace your-login with the output of "who" if you don't know who you are logged in as please try both /dev/pts/42 and pts/42 format for the tty part of write example: write trevor pts/42 When I run this I get: write: trevor is not logged in on pts/42 Even though I clearly am. This used to work perfectly up until last year (I think), and I think systemd changed something (big surprise). No chatter about this anywhere that I can see. Probably the last person on earth to use write (at least on F24). I found some other things to test that indicate that something is really amiss: >write trevor write: trevor has messages disabled >mesg is y >mesg y mesg is y >write trevor write: trevor has messages disabled >ll /dev/pts/42 crw--w---- 1 trevor tty 136, 42 Jun 28 02:48 /dev/pts/42 If someone else can confirm this bug on a non-Fedora (or a newer one) that would be great. If someone can also confirm that the above behaviour is insane, that too would be great. If anyone has some ideas on what to try next, shoot away! Then I'll file a bz. Thanks!

Huh??? I am stunned! And, it's "as of today". No prior notice? What happened there so suddenly? I am also somewhat confused by the alternative ways of buying O'Reilly books. I don't know what this Safari thing is all about for buying books - I thought Safari is an alternate browser.

laptop HD's
by Dan Keizer 10 Jun '17

10 Jun '17

OK, so first off, thanks for all your guys feedback on my prior posting about a young guy's interest in a computer gaming system. I passed along the info - not sure where/how far it went ... good info anyways. on another front, the laptops i've purchased for myself/house I've replaced the spinning metal with SSD's. I've then given some of these spinning metals away. Now, there's an interest to get a couple/few spinning metal drives to put into laptops for casual use for some other peoples ... Does anyone have any source for older laptop hd's ... even as small as 20gb or so would be fine (they are probably hard to find too) ... there's a couple i'm looking for in the next while ... Thanks. Dan.

OpenBSD In Azure
by John Lange 09 Jun '17

09 Jun '17

As a bit of an update to my presentation last month; I can't recall if I mentioned that OpenBSD was on the Azure road map or not (I meant to), but in any case, both OpenBSD and FreeBSD images are now available: https://www.theregister.co.uk/2017/06/09/open_bsd_support_comes_to_azure/ -- John Lange

MUUG Meeting, June 13, 7:30pm -- BSDCan 2017 Report
by Gilbert E. Detillieux 06 Jun '17

06 Jun '17

*** Please note the updated meeting location below *** The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, June 13. The meeting topic for this month is as follows: BSDCan 2017 Report Adam Thompson will be reporting on his recent visit to the 14th annual BSDCan. BSDCan, a BSD conference held in Ottawa, Canada, quickly established itself as the technical conference for people working on and with 4.4BSD based operating systems and related projects. The organizers have found a fantastic formula that appeals to a wide range of people from extreme novices to advanced developers. Daemon-Dash: rsync In the Daemon-Dash segment, Wyatt Zacharias will demo the rsync daemon. When run as a daemon, rsync allows clients to directly connect and retrieve files, without the need for SSH encapsulation or shell access. 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 2L17* 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: https://muug.ca/ Help us promote this month's meeting, by putting this poster up on your workplace bulletin board or other suitable public message board: https://muug.ca/meetings/MUUGmeeting.pdf -- Manitoba UNIX User Group E-mail: <gedetil(a)muug.ca> c/o Gilbert E.

Small switch recommendation.
by Sean Cody 03 Jun '17

03 Jun '17

Can anyone recommend a small switch (say 8 ports, reasonably priced) with the following properties: - Gigabit - Port Mirroring (at least 3 sets of 2 port mirrors) - SNMP (for bandwidth monitoring) - Management (SSH or Web is fine especially if SNMP is available as well). - Native IPv6 (nice to have, since my env is fully dual-stack) Was looking at the netgear 8 port thingies but I don't think they support SNMP and I'm too lazy to manually check usage with a web-ui. I've also experienced some issues with older netgear switches (purple ones) where MAC address per-port assignment was horribly broken (same MAC applied to all ports in MGMT & SNMP interfaces). Originally looking at the Ubiquiti switches to replace a 24 port unmanaged switch but realized I could just deploy this tactically with a smaller separate switch instead. The use is to be able to monitor usage as well as being able to tap specific points without futzing with cabling. I may end up just going fully managed (for device location hunting) but could use some product suggestions from the above described scenario. -- Sean
