Hello mailing list . . . This is my first post so be gentle. Most of the traffic here is way above my 'pay grade' so I just sit back and read. I have learned a lot, more than a forum. Thank You. The reason for my post is that I am moving soon and must downsize. I have a few things to give away to an educational or charitable organisation but anything other than a commercial operation in keeping with the 'free and open source philosophy' model. Over the past forty years or so I have accumulated an awful lot of electronics (now surplus!), approximately five large plastic containers full of stuff. It runs from cables (RCA, phono, USB, HDMI, SATA) (dozens), wall power supplies (110 volt USB and proprietory) (dozens), computer speakers, headphones, ear buds, USB hubs (powered and not) and even a seventies SCSI cable. I have also three LED monitors (working). In its new days there were many thousands of dollars worth of wire and plastic. It would be a shame for it to go to the local electronics recycling centre on the 19th of September where it may end up. Any offers? I am located about an hour away from Toronto. Would request you come to me. I suggest an SUV or pickup truck. For free, for any audiophiles in the audience, I have two custom built (by me) 5/4 inch solid teak speaker enclosures with three English KEF speakers, a tuned port, and 150 watt three way crossovers minus the front grills. Better get them quickly my cat has found the baffle material and is slowly removing it through the tuned port! They weigh about 20 / 25 kilograms apiece. Any offers? I would like to see them go to a good home and not a transit point to another owner, i.e. re-gifting or selling. These are not for a hand held unit but a powerful audio amplifier or receiver. I probably could throw in a Sony 300 watt receiver. I will not need it after the speakers go. Let me know. Thanks. Paul

On the information prowl
by o1bigtenor 25 Aug '15

25 Aug '15

Greetings I am in need of learning how to setup Apache2, Postgresql, NFS at the same time as I am setting up my NAS box running OpenMediaVault. OMV looks very impressive but with these plugins (and on the sides) there is a tremendous amount that needs to be setup and if its not right - - - well let's just say things are interesting. I have found over the years that man pages and tech docs for Linux, GNU and the like are written for those that really do know what they are doing and merely need a reminder to remember how to EXACTLY write something or set that something up so that a desired result happens. Now to the rest of us who use these tools and have not spent years memorizing C, C++, C#, Python, perl, sql are don't consider these our mother tongue the docs are most often less than useful and too many times less than comprehensible (one of the biggest lacks is examples of good and bad usage of commands). I have learnt my way around certain things and have almost gotten comfortable doing things 'under the hood' but being faced with all of the first paragraph (adding in remote server VirtualBox vms at the very least) is a wee bit daunting. Have found official docs but these assume a lot and as soon as there is something that doesn't work exactly as expected - - - well - - - I'm supposed to know how to modify things (by osmosis I think!). Does anyone out there have suggestion(s) on how to guides for setup, modification and learning at least the first 3 listed? I would be very grateful to find (have already spent many hours looking for how to do things using duckduck) some straightforward guides. When I try to look for something specific like Apache2.2 - - - well all too often its for 2.0 or 2.4 or its 8 years old and nothing in Debian 8 is even similar (different file names for example). I have been trying to keep a log enumerating what I am doing so that hopefully my experiences will be useful for some for at least a short while. TIA Dee

NetworkManager scans wireless every 2min -- solution (finally)
by William Park 19 Aug '15

19 Aug '15

My wireless connection crawls for 20sec every 2min. NetworkManager was scanning my wireless network every 2min (iwevent says so). The problem is that the scan lasts 20sec, and during that 20sec, I get the following dmesg messages: ieee80211 phy0: rt2x00queue_flush_queue: Warning - Queue 2 failed to flush and my connection crawls. The card is Linksys WMP600N (rt2800pci). I tried different kernels, different driver settings, different NetworkManager configurations, etc. Since it's the only wireless card I have, I couldn't try different card and didn't feel like buying another. Finally, an accidental click led me to a solution: To prevent NetworkManager from scanning, set BSSID to the MAC address of access point. -- William

Poweredger server question
by o1bigtenor 18 Aug '15

18 Aug '15

Greetings Managed to buy a Dell poweredge 2950II server. What an odyssey to set up the bios!!! I have 2 drives I got with the machine - - - they were part of a Raid 5 array. Now there are only 2 drives (will never by a raid 5 array by definition) and I need some way of formatting them so that I can turn them into a Raid 1 array. (Its all hardware raid on this box.) Anyone with any idea on how to do that to scsi drives when the controller won't let me change their settings and I have no other pox to put them in. (Connector is a wee bit different than for SATA!)

hardware inventory -- what's in my machine?
by D. Hugh Redelmeier 17 Aug '15

17 Aug '15

Sometimes I don't remember what's in each of my machines. Here's what I use to figure this out: - taking the machine apart (often inconvenient) - dmesg(8) shows the kernel log. If nothing has flooded the log it will still have the messages from the booting. You can see entries from the kernel's discovery of most resources. Downside: it is long and arcane. Upside: you might find some surprises (eg. warnings). - dmidecode(8) "DMI table decoder". The output is a little arcane but useful. The man page says that it can be unreliable. - (new to me) lshw(1) "list hardware". The output seems easier to read that dmidecode's. It uses a variety of sources. It can output in a bunch of formats (but I've ignored that). - /proc/cpuinfo will tell you about the CPU. Apparently lscpu(1) shows pretty much the same thing (I've never noticed it before). - /proc/meminfo will tell you how much RAM you have (MemTotal is roughly the physical RAM, after some overhead has been removed). - /var/log/Xorg.0.log: shows what devices and capabilities X has found. Hard to read but sometimes it's what you need. - lsusb(8): list USB devices (including hubs). - lspci(8): list PCI devices and buses - sdparm(8)/hdparm(8): show (or set!) parameters of disk drive. hdparm seems to be mostly obsolete. This will tell you stuff: sudo sdparm -i /dev/sda - smartctl(8) "SMART Monitoring Tools". SMART == Self-Monitoring, Analysis and Reporting Technology. This is about disk drive issues. This command will pour out a lot of information: sudo smartctl -x /dev/sda

Ubuntu (or debian): apt-get auto-remove?
by D. Hugh Redelmeier 17 Aug '15

17 Aug '15

After my update from Ubuntu 12.04 to 14.04, apt-get tells me that there are a lot of packages that apt-get auto-remove could remove. Is that safe? What is the underlying idea? I think that it removes things that were added due to dependencies where those dependencies no longer exist. In the back of my mind, I worry that sometimes dependencies might be things that I wanted independently of why they were installed, but I'm not sure of that. Do people fine apt-get auto-remove works great or do you find that it throws a few babies out with the bathwater?
