Internode + Nodephone + Asterisk (+FreePBX?)
by Michael Schams 18 Oct '16

18 Oct '16

Hi there, We are planning to switch from a standard phone line to Nodephone VoIP from Internode. I am very keen to test if Asterisk (maybe in combination with FreePBX) is an option for a small team (one trunk, 6 to 8 endpoints, all with various SIP clients). I successfully set up Asterisk 13 and pjsip and FreePBX 13 on a pretty standard Debian 8 box. I suspect the challenges start when it comes to the VoIP SIP details for the trunk. I came across a few forum posts and discussions about the Internode settings, but I wonder if anyone from the LUV community runs such a setup or has some experience with Asterisk and Internode (especially their Nodephone product)? As I pointed out above, we don't have the line yet, so it's more curiosity than a specific problem I want to solve (yet) :-) Any feedback is welcome. Cheers Michael

Hi Glenn, SUCCESS! Thankyou. Even the printer is working correctly. My daughter will love this, and I am very grateful, and moreso for the education. I can get some sleep now.

Brother scanner driver
by Bob 17 Jun '16

17 Jun '16

Hello all, I have set a box for a friend running Kubuntu 16.04 with a brother MF7680DW multifunction printer/scanner attached via usb. I have installed the latest drivers from the Brother website and the printer works fine but the scanner is not found by any scanning program. Research indicates that there is a permissions issue error. The solution is to run |sudo chmod 666 /dev/bus/usb/001/002 |which fixes the usb bus permissions problem and the scanner is found. Am I able to place this command somewhere so that it is executed on startup? How do I overcome the issue of needing root access? Thanks Bob

Photobooth help
by Andrew Greig 16 Jun '16

16 Jun '16

Hi all, I have installed inotify-tools, and now the watch sets up nicely, but the print and move are not working andrewg@linux-ltv0:~> ./photobooth-hp Setting up watches. Watches established. lpr: Error - unable to access "/home/andrewg/Pictures/Webcam/2016-06-15-223028.jpg.8QE9IY" - No such file or directory mv: cannot stat ‘/home/andrewg/Pictures/Webcam/2016-06-15-223028.jpg.8QE9IY’: No such file or directory I don't know where the suffix after the .jpg is coming from, is that what is stopping the progress? Here is the script #! /bin/bash inotifywait -m -e close_write ~/Pictures/Webcam --format "%w%f" | \ while read filename; do lpr -P Photosmart_C5200 "$filename"; mv "$filename" ~/Pictures/Webcam/printed; done The print spool name is correct. Once the party is over I will play with Darktable and tethered shooting and specify a new Directory to watch. In theory the flash on the Eos should fire and give an outstanding result. Many thanks Andrew Greig

Re: Photobooth script - needs help with inotify

Thanks Glenn, As I recall it was you who helped me back then. When I promote Linux, I always talk about the community, and I use you as an example. You are right, it helps if the program is installed. I thought because the man file was there, that the program was also there. I have more work to do yet, but I will get on to it tonight. Again, thankyou Andrew Greig On 14 Jun 2016 11:19 pm, "Glenn McIntosh via luv-main" <luv-main(a)luv.asn.au> wrote: On 14/06/16 21:08, Andrew Greig via luv-main wrote: > I know that 4 years in Linux is a long time, so I was not surprised to > find that the script failed because the inotifywait command is no longer > recognised. I am not skilled in scripting but I did read the man file. The inotify-tools package is still available on Debian based distros and probably the others (though it may not be installed by default).

Photobooth script - needs help with inotify
by Andrew Greig 14 Jun '16

14 Jun '16

Hi all, 4 years ago one of the members of this list, responding to a question I posed on the "Linux Answers" site, supplied me with this script which met my need for a photobooth running with Cheese. #! /bin/bash inotifywait -m -e close_write ~/Pictures/Webcam --format "%w%f" | \ while read filename; do lpr -P HP "$filename"; mv "$filename" ~/Pictures/Webcam/printed; done I know that 4 years in Linux is a long time, so I was not surprised to find that the script failed because the inotifywait command is no longer recognised. I am not skilled in scripting but I did read the man file. My questions are, do I substitute in_add_watch instead of inotifywait? Do I keep the rest of the line the same? Many thanks Andrew Greig

Epson V350 scanner contrariness.
by Erik Christiansen 10 Jun '16

10 Jun '16

My Epson V350 scanner worked fine with ubuntu 10.04 and iscan, but it's hiding from the latest iscan on debian 7, giving "Could not send command to scanner. Check the scanner's status." It has power, and the steady green status LED indicates "Ready to scan". The iscan version is from the latest iscan-bundle-1.0.0.x86.deb downloaded from http://support.epson.net/linux/en/iscan_c.html today. The USB connection & scanner interface are OK: $ lsusb Bus 001 Device 002: ID 04b8:012f Seiko Epson Corp. Perfection V350 (GT-F700) Trying to probe a bit more: # sane-find-scanner ... found USB scanner (vendor=0x04b8 [EPSON], product=0x012f [EPSON Scanner]) at libusb:001:002 ... Try scanimage -L and read the backend's manpage. ... The latter doesn't work, because the V350 isn't supported by Xsane, but that wasn't an issue for iscan, AFAIR. (It is, after all, specifically for Epson scanners.) $ groups erik cdrom floppy audio dip video plugdev scanner bluetooth netdev +++++++ It would be damned convenient if I could manage to scan a few documents in the next few days, so any ideas on this or alternative apps would hit a dry spot. The debian gui "Simple Scan" clicky-thing says "No scanners detected". Multiple google hits suggest it is also a Sane front-end. Erik (Back to the intertubes, for more inspiration. There has to be something out there.)

free PowerEdge Tower server (workstation)
by Russell Coker 09 Jun '16

09 Jun '16

http://www.cpubenchmark.net/midlow_range_cpus.html I have a tower server with an AMD Athlon 1212 CPU and 8G of ECC RAM to give away. The above URL has the relative performance of the CPU (it beats the i3 and Core 2 Duo systems but doesn't compete with the quad core CPUs). The CPU lacks the feature needed for KVM, if you run QEMU it will be in software emulation mode which is really slow. It used to be a Xen server. It has PCIe*8 slots so you can't install a decent video card without using a saw. All RAM slots are full and I think it uses unbuffered DIMMs so expanding the RAM probably costs more than it's worth. If you need a 64bit dual-core server with 8G of RAM then this will probably work quite well. It can work as a desktop system (and did so well for a few years), but the inbuilt graphics is slow. It makes little noise if you have a SSD and the CPU is mostly idle. I can bring it to a LUV meeting. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

MySQL Galera (Percona XtraDB Cluster) aborts on startup after successful SST
by Chris Samuel 08 Jun '16

08 Jun '16

Hi folks, Anybody got any clues about what to do when the sole message you get regarding a problem when starting up Percona XtraDB Cluster (basically MySQL with Galera clustering built in) is just this? Jun 8 11:43:58 hostname mysqld: 160608 11:43:58 [ERROR] Aborting It's preceded by lots of log messages about a successful SST and followed by lots of log messages about it successfully shutting down but it seems to be missing the bit where it says *WHY* it's aborting.. :-( The version information is right before that abort message, and says: Jun 8 11:43:58 hostname mysqld: 160608 11:43:58 Percona XtraDB (http://www.percona.com) 5.5.41-37.0 started; log sequence number 876619301144 There's more context over on my post on the Percona forums here: https://www.percona.com/forums/questions-discussions/percona-xtradb-cluster… Anyone got any ideas at all about how to get more info out? cheers!
