Firewall log entry
by steve-ALUG＠hst.me.uk 26 Jan '16

26 Jan '16

Hi y'all! I'm confuzzled. I have repeated entries in my syslog in log file viewer. Jan 26 08:31:42 MYSERV kernel: [25624.013276] [UFW BLOCK] IN=eth0 OUT= MAC=BIG_MAC SRC=192.168.1.1 DST=224.0.0.1 LEN=28 TOS=0x00 PREC=0x00 TTL=1 ID=0 PROTO=2 Jan 26 08:31:42 MYSERV kernel: [25624.013768] [UFW BLOCK] IN=eth0 OUT= MAC=BIG_MAC SRC=192.168.1.1 DST=224.0.0.1 LEN=32 TOS=0x00 PREC=0x00 TTL=1 ID=0 PROTO=2 Jan 26 08:33:48 MYSERV kernel: [25750.017039] [UFW BLOCK] IN=eth0 OUT= MAC=BIG_MAC SRC=192.168.1.1 DST=224.0.0.1 LEN=28 TOS=0x00 PREC=0x00 TTL=1 ID=0 PROTO=2 Jan 26 08:33:48 MYSERV kernel: [25750.017562] [UFW BLOCK] IN=eth0 OUT= MAC=BIG_MAC SRC=192.168.1.1 DST=224.0.0.1 LEN=32 TOS=0x00 PREC=0x00 TTL=1 ID=0 PROTO=2 Where MYSERV is the name of my server, and BIG_MAC is what appears to be a mac address but longer than I am used to . always the same number, =01:00:5e:00:00:01:a0:21:b7:43:91:37:08:00 As far as I can see, 192.168.1.1 is connecting to a broadcast address, to see if anyone's there. Thing is, 192.168.1.1 IS NOT an address that I'm aware I'm using; my subnet is 192.168.0.*. If I open 192.168.1.1 in a webbrowser, it opens a trivial webpage I have set up as an adblock-replacement page. The thing is, this web page normally serves on 127.0.0.1 On the server, if I ping 192.168.1.1 it responds in about the same amount of time as 192.168.0.1 I suspect that 192.168.1.1. is my own server bound somehow to another ip address. I doubt that this is something from outside getting in to my network. Can anyone help me find out what it is, where it is, and how to stop it? Cheers Steve

Anyone have experience of OKI printers under Linux?
by Chris Green 21 Jan '16

21 Jan '16

I'm thinking of replacing my HP printers (a mono laser and a multi-function inkjet) with a single multi-function colour laser printer. The current front runner is an OKI MC342DN. Does anyone have any experience of using OKI printers under Linux? There are Linux PPD drivers for the MC342DN but that's about as much as I can find out. -- Chris Green

Good option for occasional printing
by Steve Engledow 21 Jan '16

21 Jan '16

Printing has long been the bane of my (and I'm sure most people's) existence and several years back, I swore I would never buy another printer. However, I have a new job now which is based from my home and I no longer have the convenience of the office printer for the occasional (a couple of times a month) return label or plane ticket. What I'm looking for is something that will solve my needs for a reasonable price. The last time I bought a printer, it cost me £30 and included some ink that ran out after around 15 pages of black and white. Replacement ink cost me around £45. I've got two short words for that. Does anyone have any recommendations? I'll only need B&W, A4, and have no need for high resolution print. Cheers, Steve

Slightly OT for the list: - GPG bad signature
by mick 20 Jan '16

20 Jan '16

Hi Guys Steve tells me that he had a problem with my last email to the list (Re: Rural Broadband). He got a bad signature from GPG. In a follow up exchange off list Steve said: "Here's what gpg says: --- $ gpg -v --verify signature.asc msg gpg: armor header: Version: GnuPG v2.0.22 (GNU/Linux) gpg: Signature made Tue 19 Jan 2016 14:04:01 GMT using RSA key ID 5BADD312 gpg: using PGP trust model gpg: BAD signature from "Mick Morgan (Mick's new 4096 bit key) <mick(a)rlogin.net>" [unknown] gpg: textmode signature, digest algorithm SHA256, key algorithm rsa4096 --" Ive been using this key since the middle of 2012. I have also been using claws (with PGP/MIME enabled) as my MUA for ages. There seem to be a couple of reasons why GPG should complain. The most obvious is that the email has been changed after signature. Paranoia aside, this can easily happen if the MUA (at either end?) changes the mail by wrapping at a particular line length. Another possible reason is that my signature key length (4096 bits) is too long for the recipient's system to handle correctly. But as I say, I have been using the current key for nearly four years now, so my question is, has anyone else seen this problem with my signature? And does anyone know what may be going on here?

Rural Broadband
by Laurie Brown 20 Jan '16

20 Jan '16

Hi folks, I know this question has been asked here before, but it was ages ago, and things change quickly. I have a client who is 1.8 miles form the nearest exchange, who is getting appalling line speeds. She's been with Eclipse for years, and like me, has found their support getting steadily worse. Recently, it took then 45 hours to respond to a support call from me which I regard as utterly unacceptable. I'm looking for another supplier for my rural clients as well as myself (I can get fibre). This particular client has speeds of Down: 1.8 and Up: 0.3. As she runs an office from home, this is clearly unacceptable. The line has become steadily worse over the last couple of years, and she has received absolutely nothing but obfuscation and requests for more money from both BT and Eclipse. She's tried Bonded DSL, but was told that it didn't work because she uses VOIP. No, they won't retract that. She has a spare line, equally slow, effectively unused now. So, my question is, do any of you out there have any recommendations for getting the best rural broadband? Suppliers, methods, etc.? She does need static IP if at all possible. It can be worked around, but that's not ideal. Cheers, Laurie. -- --------------------------------------------------------------------- Laurie Brown laurie(a)brownowl.com ---------------------------------------------------------------------

iPlayer improvements
by Chris Walker 18 Jan '16

18 Jan '16

I know that some here use get_iplayer to grab BBC files. Perhaps those people would like to know that the BBC are experimenting with 320k aac downloads. To make use of them you need a 'dev' version of get_iplayer available from the git resource. There are only a few files available so far apparently but nonetheless, if you want to experiment, feel free. If you want to know some of the background to compression etc, you might like to listen to this - http://www.bbc.co.uk/programmes/b06tvgp1 -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

Re: [ALUG] Printing
by Christopher Dawkins 15 Jan '16

15 Jan '16

> 1. Good option for occasional printing (Steve Engledow) I have an LJ6M that is nearly twenty years old and still working, although it occasionally mangles the paper. However, I now mostly use an HP OfficeJet Pro 8620, which did cost £130. But (with an extra eight pounds or so on the PrinterShare app) it prints documents wirelessly from my Android as well as via CUPS (I hate CUPs, by the way) from all my Linux/FreeBSD machines, it's a colour photocopier, it sheet feeds and it duplexes, and the cost per print seems fine once you get onto the big cartridges. Whatever, the ability to print email attachments from a the comfort of a phone is worth a lot to me! Colour photographs need expensive paper, however: the colour laser I had before this did colour photos well on normal paper. -- Christopher Dawkins Garnetts Corner, Jollyboys Lane North, Felsted, Dunmow, Essex CM6 3DU cchd(a)pjcd.org 07816 821659 01371 821076

No space for Audacity
by Chris Walker 13 Jan '16

13 Jan '16

I'm having a problem with my system and I can't see where the solution is despite looking online. Audacity said that the disc was short of space and just sat there doing nothing. So I killed the task and looked at the space with 'df'. It shows that /dev/sdb5 has zero space left. Here's the relevant output from df :- Filesystem Size Used Avail Use% Mounted on devtmpfs 3.0G 0 3.0G 0% /dev tmpfs 3.0G 1.4M 3.0G 1% /dev/shm tmpfs 3.0G 940K 3.0G 1% /run /dev/sdb5 7.6G 7.2G 0 100% / /dev/sdb7 7.6G 5.6G 1.7G 78% /usr tmpfs 3.0G 0 3.0G 0% /sys/fs/cgroup tmpfs 3.0G 88K 3.0G 1% /tmp /dev/sdb8 849G 202G 647G 24% /home tmpfs 597M 12K 597M 1% /run/user/1000 So where has the 7.6 gigs worth of space gone on sdb5 or am I looking in the wrong place ? -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

PUA Win 32 files?
by Bev Nicolson 04 Jan '16

04 Jan '16

So I ran ClamAV a while back and as usual it identified four Win.32 files from usr/lib/momo/4.0mscorlib.dll as potentially dodgy. (Same files as this questioner had: http://askubuntu.com/questions/583729/clamav-pua-win32-packer-privateexepro… ) My questions are 1) Are they dangerous? Opinion seems divided on this. 2) If I deleted them anyway, just in case, would I do my system any harm? Bev.

Minimal mail sending
by Mark Rogers 05 Dec '15

05 Dec '15

What's the simplest (least config, lowest footprint) way to give a Linux box the capability to send email? Eg: if I have a Pi running a few cron jobs and I want it to be able to email me any issues, that kind of thing. Or a web server that might need to send forgotten password reminders but little else. It'll never need to receive email or provide mail services to others. I've used ssmtp in the past but recently found something better, but for the life of me can't remember what it was! But as it's a common requirement I'd like to know what other people do.

New Server recomendations
by steve-ALUG＠hst.me.uk 25 Nov '15

25 Nov '15

Hi folks. I'm going to have to replace an ancient Pentium (2?) with 2gb ram that's run as a file server with software raid (twin disks), media server, print server, web server. None of these are high use and the web server is only internal. Anyone got any recommendations for a low-ish power, small-ish form factor machine that will run linux that I could use? Existing machine is running Ubuntu, and I'd probably continue with that, or Lubuntu, or possibly debian. Also is there any easy way to migrate from the existing machine to the new one? Presumably I can't simply move the disks from the old machine to the new one? (This bit's a bit off topic- sorry) Also probably got to get sprog a Windows machine. It's a long time since I've delved into the wacky world of windows. Schoolwork and games like train simulator and minecraft would probably be it. Can't decide for sure, but probably a laptop. Any good deals or recommendations? TIA Steve

MP3 detected but not opened
by Bev Nicolson 24 Nov '15

24 Nov '15

Now, given my last few questions I may regret asking this but here goes anyway. I've got an MP3 player. (Philips GoGear, if that's any help.) It used to be opened automatically when I plugged it into my computer but it doesn't now, though it is recognised. (14.04LTS.) It's just a problem with this device. (A bit of me is wondering if it's like the sound problem I had briefly. All I had to do was find Sound in a menu and un-mute.) Bev.

Font config ?
by Bev Nicolson 20 Nov '15

20 Nov '15

When everyone's exhausted the mice jokes (pesky meeces) can you apply your minds to this. I have googled and see it's a common problem but didn't understand the solution. While I was upgrading to 14.04, a message came up to say 'font config out of memory lines 14, 23 and 32.' It now says this when I switch the computer off. So, what does it mean and how do I fix it?

Mouse trouble
by Bev Nicolson 20 Nov '15

20 Nov '15

Not sure what's up with my mouse. I asked someone in a reputable computer shop recently about the fact that my mouse exhibits odd behaviour. It'll crash if I have two browsers open and playing a video, for example. He suggested upgrading to Ubuntu 14.04LTS. Which I have done and it's worse. Switching off and on again is the only thing that works. New mouse? Bev

Simple CCTV app
by Mark Rogers 18 Nov '15

18 Nov '15

I have a couple of Wifi IP cameras that I'd like to record output from. I can either capture an image or (I think) an RTSP stream. I just want to store them somewhere I can refer back to them in future if needed. Ideally making efficient use of storage. Any suggestions? At the moment I have ZoneMinder installed but it's quite big and heavy, I frequently find it isn't running (eg after a system update) and it stores all the images as JPEGs rather than as a movie, where I would have thought that the latter would be rather more efficient. It crossed my mind I could probably script something that captured images at a regular frame rate and then turned batches of them into videos later, but there's probably a way to avoid reinventing the wheel. Note: The camera is constantly seeing motion (it's view is through a tree apart from anything else) so motion detection isn't much use unless it can be quite intelligent. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Case insensitive scripting
by Chris Walker 15 Nov '15

15 Nov '15

Hopefully somebody can point out my error with a script. This is it =================== #! /bin/bash # Script to extract thumbnails from .ts files for use on a Humax machine set -e # set -x # shopt -s nocasematch for FILE in *.ts do bname=$(basename "$FILE") dir=$(dirname "$FILE") # extension="${bname##*.}" filenamewoext="${bname%.*}" imagefile="${dir}/""${filenamewoext}.png" ffmpeg -i "$FILE" -vframes 1 -ss 00:01:00 -f image2 "$imagefile" done =================== My problem is that I can sometimes have .ts files and others .TS files so how do I persuade bash to search for both case types? As you can see, I've tried setting 'nocasematch' but it's commented out as that doesn't seem to work for me. Searching online produced the 'tr' command but how do I apply that, if indeed it is the correct solution? Any help appreciated. -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

Has anyone used or know anything about FibreWiFi Limited?
by Chris Green 15 Nov '15

15 Nov '15

While searching around recently for good broadband deals I came across FibreWiFi Limited. They offer direct WiFi (as in microwave based) internet connections. The prices seem quite reasonable, see:- http://www.fibrewifi.com It looks like we should be covered looking at their coverage map. So I'm very interested. Does anyone know anything about them? -- Chris Green
