Multi Screen Remote Desktop in Windows (multi/dual screen rdp)

2W1ETN — Mon, 30 Nov 2009 12:43:46 +0000

I have a client that needed access to both his screens from his home office PC. He was aware of options like LogMeIn but was reluctant to pay for an app which seems to want to charge you a subscription.

After hunting around on the net for a couple fo minutes the solution became apparent. You can use Windows Remote Desktop/RDP to connect multi monitors.

Save the RDP connection and then create a shortcut to:

mstsc.exe /span c:\1.rdp

1.rdp being the RDP file saved from the Remote Desktop Connection app

Adding user for Linux Samba/SMD shares

2W1ETN — Sat, 28 Nov 2009 14:20:35 +0000

Samba uses tdbsam by default to manage SMB password, that’s the password used to logon over Windows Networking.

Adding and managing users

In this example, I will add a user called damien. You can add as many users as you need in the same way, just replace the username tom with the desired username in the commands.

useradd damien -m -G users

Set a password for Damien in the Linux system user database. If the user Damien shall not be able to login to the Linux system, skip this step.

passwd damien

-> Enter the password for the new user

Now add the user to the Samba user database.

smbpasswd -a damien

-> Enter the password for the new user

Getting Music on Hold working in Trixbox/Asterisk

2W1ETN — Sat, 28 Nov 2009 13:41:02 +0000

OK So I’m running FreePBX 2.5.1 as comes with Trixbox. I go to get Music on Hold working and as with Open Source projects you need to get the little things like MOH working yourself.

If you have the same problem then you probably need to install mpg123.

From the Console logon as root and run the following:

rpm -Uhv http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm

or if using a non 64bit system then:

rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

yum install mpg123 sox

mkdir /var/lib/asterisk/mohmp3

chown asterisk:asterisk /var/lib/asterisk/mohmp3

chmod 755 /var/lib/asterisk/mohmp3

cp /var/lib/asterisk/moh/* /var/lib/asterisk/mohmp3/

Checking your Interface/s Status on Cisco IOS Routers

2W1ETN — Thu, 26 Nov 2009 16:12:53 +0000

Enabling HTTP Server on Cisco IOS Routers

2W1ETN — Thu, 26 Nov 2009 12:05:34 +0000

Enabling the HTTP server on Cisco Routers is easily done using the console port or via an SSH connection.

You might wonder why you’d want the HTTP server running; well you need it if you want to install SDM (Cisco Router and Security Device Manager)

To enable the web server logon or connect via terminal

Then type the command

enable

Then type

config

Press enter to config from the terminal when prompted

You should see a prompt like (Which is the config prompt):

Router(config)#

Enter the following commands

ip http server
ip http secure-server
ip http authentication local

If you intend to install SDM or want to be able to access the router from SSH then you need to add a user account as below:

Username sdm privilege 15 password 0 sdm

That will create a user with the username and password of SDM

If you haven’t enabled SSH and or telnet do so using the following commands:
line vty 0 4
login local
transport input telnet ssh

Compiling FFMPEG for Microsoft Windows

2W1ETN — Tue, 11 Aug 2009 11:06:01 +0000

Installing FFMPEG from the source in window platform is easy as you do for other window application. Here is the complete instructions how to build FFMPEG in windows.
To install FFMPEG on windows you need to install third party MinGW and MSys library that is compatible with GCC. This library is required to build ffmpeg in windows and support shell to run commands.

Download MinGW and MSys

MinGW: MinGW Direct download link

MSys: MSys Direct download link

SF Link: Sourceforge MinGW MSys Package Download Page

FFMPEG: FFMPEG

Building FFMPEG

It is time to install ffmpeg. Extract downloaded ffmpeg archive in c: folder. If you have not downloaded yet please download now then run MSys.bat file from C:\msys\1.0\ folder. This location will be depend on you MinGW and MSys installation. In the command prompt run the following commands:

$ cd c:/ffmpeg-0.4.7

$ ./configure –extra-cflags=”-mno-cygwin -mms-bitfields” –extra-ldflags=”-Wl,–add-stdcall-alias” –enable-mingw32 –enable-shared –disable-a52 –disable-pp –disable-ffserver –disable-ffplay

$ make

Com0Com Windows Vista X64

2W1ETN — Wed, 24 Jun 2009 10:14:39 +0000

I needed some virtual com ports on Windows Vista for the car PC. Basically to get the Flex Radio 3000 interfacing with the Ham Radio Deluxe you need to interface via a com port.

I decided on Com0Com as the virtual com port driver, thus downloaded it from http://com0com.sourceforge.net/

Installation went ok until I got up a nice message about unsigned drivers, similar to this:

(Note that’s not exactly the same error as the driver is different, but the message and problem are)

Basically in Windows Vista x64 you cannot allow unsigned drivers to be installed. Even using BCDEdit to allow unsigned drivers doesn’t work as Microsoft has applied a number of security patches to prevent it. The only way to do it, is to press F8 on window boot and select the option which allows for unsigned drivers.

I don’t want to be pressing F8 every time I reboot the computer, as after all its designed to be in the car and getting the keyboard each time will soon become tiresome. Luckily I came across ReadyDriver which lets you boot from a CD Image, USB Stick or Floppy and it basically presses F8 and selects the options for you. That said I dont want to boot from a CD or any other external device. A bit more research and I was sent a copy of ReadyDriver Plus which basically installs a bin boot image and extends the Windows Boot Manager to boot into it and does the rest for you.

I’ve uploaded version 1.1 of the software, as it got sent to me and I’m not sure where from.
