11 Aug '15

Hey Gang, This is a reminder that we have a WLUG meeting! Date and Time: Thursday August 13th at 7pm! Location: Campus Center Mid Century Room (rm 331) Topic: Software Defined Networks! Frank is going to be doing a talk to Software Defined Networks (SDN's). What they are, what they do, why they're better than traditional networks. Refreshments: will be provided and we'll retire to Tech Pizza to continue the conversation. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

I actually would be interested in hearing about that. The whole SDN buzzword gets thrown around a lot without any real explanation.

You can reply directly to codevark(a)aim.com. ZoON PS: I have all sorts of rare and bizarre hardware and other stuff -- if you're interested in anything you can just take it.

ZFS Fun!
by Tim Keller 08 Jul '15

08 Jul '15

During my talk, I spoke briefly about upgrading one of my machines from 3TB disks to 4TB disks. Here's a "zfs status" output (obviously with some critical details scrubbed) This is a raid 60 (4, 8 disk raid 6's). I'm replacing 4 disks, one from each of the strip sets. What I captured this output I'd just put in the fourth disk. So that 252h is now down to 15h, and likely soon it'll be even lower. Obviously, I/O load on the subsystem will cause this to stretch out. Note the "New Disk" labels were added for emphasis. bash-4.2# zpool status XXXXXX pool: XXXXXXX state: DEGRADED status: One or more devices is currently being resilvered. The pool will continue to function, possibly in a degraded state. action: Wait for the resilver to complete. scan: resilver in progress since Wed Jul 8 10:30:22 2015 945M scanned out of 11.9T at 13.7M/s, 252h54m to go 945M scanned out of 11.9T at 13.7M/s, 252h54m to go 110M resilvered, 0.01% done config: NAME STATE READ WRITE CKSUM XXXXX DEGRADED 0 0 0 raidz2-0 DEGRADED 0 0 0 c3t5000C500637AADD3d0 ONLINE 0 0 0 replacing-1 DEGRADED 0 0 0 c3t5000C50064E9441Fd0 FAULTED 1 166 0 too many errors c3t5000C500637875EBd0 ONLINE 0 0 0 (resilvering) <---- New Disk c3t5000C5004DFE165Ad0 ONLINE 0 0 0 c3t5000C5004E0F3A80d0 ONLINE 0 0 0 c3t5000C5004E1B6EE1d0 ONLINE 0 0 0 c3t5000C5004E23870Bd0 ONLINE 0 0 0 c3t5000C5004E2AC08Fd0 ONLINE 0 0 0 c3t5000C5004E2AE946d0 ONLINE 0 0 0 raidz2-1 DEGRADED 0 0 0 c3t5000C500637879E7d0 ONLINE 0 0 0 replacing-1 DEGRADED 0 0 0 c3t5000C5004E2B1B22d0 FAULTED 139 222 0 too many errors c3t5000C500637ACF67d0 ONLINE 0 0 0 (resilvering) <------ New Disk c3t5000C5004E2BE74Dd0 ONLINE 0 0 0 c3t5000C5004E2BEA7Fd0 ONLINE 0 0 0 c3t5000C5004E2C0B84d0 ONLINE 0 0 0 c3t5000C5004E2C5397d0 ONLINE 0 0 0 c3t5000C5004E2D0C39d0 ONLINE 0 0 0 c3t5000C5004E2D1F13d0 ONLINE 0 0 0 raidz2-2 DEGRADED 0 0 0 replacing-0 DEGRADED 0 0 0 c3t5000C5004E2D48F6d0 UNAVAIL 0 4 0 cannot open c3t5000C500637933B3d0 ONLINE 0 0 0 (resilvering) <----- New Disk c3t5000C5004E2D58DAd0 ONLINE 0 0 0 c3t5000C5004E2D0821d0 ONLINE 0 0 0 c3t5000C5004E2D3220d0 ONLINE 0 0 0 c3t5000C5004E2D3749d0 ONLINE 0 0 0 c3t5000C5006A581C22d0 ONLINE 0 0 0 c3t5000C5004E25DFFFd0 ONLINE 0 0 0 c3t5000C5004E129273d0 ONLINE 0 0 0 raidz2-3 DEGRADED 0 0 0 replacing-0 DEGRADED 0 0 0 c3t5000C5006A582FE8d0 FAULTED 146 130 0 too many errors c3t5000C50063747E77d0 ONLINE 0 0 0 (resilvering) <----- New Disk c3t5000C50064D9AB36d0 ONLINE 0 0 0 c3t5000C50064D98E37d0 ONLINE 0 0 0 c3t5000C50064DF7F04d0 ONLINE 0 0 0 c3t5000C50064DFAE39d0 ONLINE 0 0 0 c3t5000C50064E3CBE0d0 ONLINE 0 0 0 c3t5000C50064E401FEd0 ONLINE 0 0 0 c3t5000C5004DE878BAd0 ONLINE 0 0 0 errors: No known data errors bash-4.2# Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Flat screen monitor 19" needs fixit; free to good home
by E Johnson 28 Jun '15

28 Jun '15

The power went out here twice today. After the second event, monitor seems to have died. This is an Acer monitor, several years old. Black(ish) bezel; not glossy. Flat screen, I think 19" diagonal. Has been a very nice reliable monitor during its working life. Has choice of DVI input or the older kind of data connection, whatever that used to be. This specific batch of Acer monitors had used a type of capacitor which is known to have a higher-than-usual failure rate, and this is PROBABLY what it needs. Had a twin of this that fryolated same way 2 years ago, and a WLUG member came by & reported shortly after that he got it up & running with just the replacement of bad caps. This monitor has been very steady and reliable until this afternoon, with nice display and no dead pixels, ever. So if you are handy with electronics fixits, capacitors are cheap and you could probably get this working again with only a screwdriver, a soldering iron and a little bit of fiddling. Might be nice for the kid's playroom or the back office, or something. I don't know how nice games look on this monitor, since I don't do gaming. Videos always looked perfectly fine with good color. PM me if you think you want this, since I have to get down under the work table to unplug the power cord & I'm not as spry as I used to be, but can do as long as my knees aren't required to do anything radical before Noon. Pickup after Noon any day, & evenings even sort-of late-ish are okay. I can meet you at the door with this. I'm in Worcester near Elm Park. Rather give this away here than trash it, or Freecycle... first dibs to WLUG. Best wishes, Liz J

WLUG bbq thurs july9 7pm boylston MA
by Doug Mildram 24 Jun '15

24 Jun '15

Announcing (with Tim's blessing/OK) our next meeting is the WLUG summer BBQ at my house ; 540 linden st, boylston ma. <= 20min from worc via 290, .....so many other ways to get here from north/190 ; east/495, etc. Thurs July 9 at or before 7pm. Food details later. BBQ's don't need a topic, but I would love to keep doing+learning a LITTLE with -- freeNAS : my own home server works enough to NOT wanna break it, but smbd isnt working yet ( want to share with win doze) -- other ZFS-able boxes (e.g. my junker/re-loadable PC has pc-bsd with issues, want it to catch ZFS snapshots over ssh for backups ..how hard could that be?) -- chainsaws, musical instruments, tricks+treats for golden retrievers and a cat (just kidding for the meeting, but now you know way too much about me) Maybe someone else wants to bring a tower/PC for abuse or argument e.g. loading something like the above top 2, then studying the result. Or not? What did I forget besides food? -doug also with wife's blessing, if I do all the work.

Today's Topics: 1. Re: ls character range wildcard oddity? (Dennis Payne) Interesting. I see the same behavior. Near as I can tell bash decided that the alphabet is: aAbBcCdD... I wouldn't expect that to be the case but when I played around with various file name that was the behavior I saw. So [a-c] includes upercase B while [a-b] does not. 'ls [A-c]*' will show Berry but not apple. On Fri, 2015-06-19 at 09:29 -0400, Brett Russ wrote: Can someone explain this to my evidently inadequately caffeinated brain?

Minecraft server security ...
by David Glaser 21 Jun '15

Folks, My grandson wants to host a minecraft server party for his boy scout troop and my daughter and I are wondering how to ensure that the existing machines on her home network are not compromised given that the members of the troop will be bringing their own machinesand ethernet switchesalthough some may be running wireless. I was wondering if you could give us some thoughts on how to set up the network. It is my understanding that the minecraft clients do need to get out to the internet to obtain a valid player name. I had thought ofsetting up a seperate Router/Lan for the party, disconnecting the existing router/lan from the wan and connecting the minecraft router/lan to the wan for the duration of the party. Any thoughts out there? -David
