VLC Streaming

Sun, 03 Apr 2016 18:44:00 +0000

Here is my setup to use VLC running on a laptop with a webcam as a simple CCTV system that can stream to your mobile.

VLC was installed on a laptop running Ubuntu 14.4. The webcam input stream was found at

v4l2:///dev/video0

and the audio input was found at

alsa://hw:0,0

using the command line for VLC I started capturing these two devices, transcoding and streaming to http with the following script

For some reason .asf was the only encapsulation that worked, the filename you set pics the encapsulation. You can do all of this via the VLC gui, but you will need to change the string on the last page if you want a username and pass as VLC does not set that by default, instead sets the dst only.
Create the necessary port forward in the router if you wish to access via WAN, or leave locked down if using local only.

On the receiving device open VLC and open ‘Network Stream’ as http://[username]:[password]@[wanip or localhost]:[port]/[file]. E.g. http://jsmith:mypass@1.2.3.4:8080/go.asf

A bit more long winded but can also can be done via the VLC GUI :

File/Disk Browsing
Lists summary size (-s) in Gb/Mb/Kb (-h) units for all sub-directories of the current path (./*)

# du -sh ./*

Show everything, human readable file sizes, in a list

Pipes
Use the | after the first command to pipe the output to the next command e.g. Show all processes with the string apache in the command

#ps | grep apache

Screen
Is a pretty handy tool if you do much work via an SSH terminal

Launch app

# mount.cifs //Server/Share /mnt/win7/test -o username=xxx,password=xxx

This command will mount the folder ‘Share’ hosted on ‘Server’ into the nix folder /mnt/win7/test

IP PBX / 3CX / VoIP Phone System

Thu, 31 Oct 2013 08:34:00 +0000

Just finished a few days training on 3CX systems, and a very interesting two days it was. The trainer William has a distinctive style and great dry sense of humour that kept everyone engaged.

3CX is a windows base IP phone system. In the simplest terms for a small office you install 3CX on a desktop PC, sign up to a VoIP provider (e.g. VoIP Unlimited or Spitfire) plug in a few IP phones to your Ethernet, configure, provision and away you go. As it’s all IP based you can get a phone number in any region of the UK or any country for that matter. So office based in Scotland, but clients all in London, or France - get a local number to your clients and you are only paying for ’local’ calls. 3CX can go all the way up to a multi-location offices / call centres with thousand of agents. If you want to get fancy there are APIs and custom programmable elements to build your own digital receptionist, the kind that ask for your account numbers, report information from your account after you authenticate etc etc.

You can also get an app on your iPhone/Android to be able to make calls over 3G data or wifi via your 3CX PBX. Although if you want total flexibility on remote mobile access you do face the difficult decision on how to deal with security threat of opening a port for SIP traffic on your firewall to the public internet which is not a great idea.

SVN / Subversion / Source Control

Fri, 19 Jul 2013 19:38:00 +0000

Quick ‘what I did’ to setup Subversion this week to deal with SSRS projects and reports.

Installed the standard edition of VisualSVN Server
http://www.visualsvn.com/server/download/

Installed TortoiseSVN on users machines
http://tortoisesvn.net/downloads.html

The setup on the server was very easy, added users via the management interface, set the port and made sure the firewall was going to allow the connections. Created a couple of repos for the various project files.

On local PC checked-out the repo folder to a local drive folder and added the project files, simply right click to commit the files to the repo - marking all the files to be added.

Logging all the commits makes it very easy to roll back and check on what activity is going on. Clearly it makes sense to split out as best you can the different projects into . I did notice it’s worth it to un-version the user file that each project creates by default.

Next thing to try is the VisualSVN plugin for visual studio which requires TortoiseSVN to work. And read the rest of the manual as TortoiseSVN politely recommends…

Edit: Now also added the Visual Studio plugin from VisualSVN, which is fantastic and very straight forward. Do all your commits, check the logs etc from within Visual Studio.

SMTP test from telnet

Sat, 22 Jun 2013 14:23:00 +0000

Need to test out access to a mail server?

From GNU/linux is easiest, fire up the terminal

You will need your username and password as base64, to get these use perl

perl -MMIME::Base64 -e ‘print encode_base64(“username”);’
perl -MMIME::Base64 -e ‘print encode_base64(“password”);’

Save this output to use later

telnet mail.yourserver.com 25
EHLO mail.yourserver.com
AUTH LOGIN
[paste in your base64 username]
[paste in your base64 password]

Now you know if your server is working with those access details or not…

Windows Live ate my SMB share...

Tue, 21 Sep 2010 21:30:00 +0000

Have just spend way too long trying to work out why xbmc could no longer connect to a win7 smb share. The solution after much head scratching, simply uninstall Windows Live Login Assistant. Why this application should block shares from xbmc is beyond me. I have no idea what I was thinking about when I recently installed the Windows Live software anyway, most of it easily replaced by better programs. The guys at xbmc.org made a nice post on their forum about win7 smb shares, the windows live bug is mentioned there quite a bit.
