Setting up two printers on a single machines

If you have only one parallel port and need to connect two printers check to see if one has an ethernet port with an RJ45 connector, if so here is what you do:

Connect up your parallel port printer as needed and install as neccesary with drivers and such.

Find yourself a cross-over cable and and extra ethernet card, and manually connect up the second printer to the new network card.

Manually configure the second ‘Local Area Network Connection’.

Most probably the following setting will work on a Windows~ machine.

IP 192.168.2.1

Subnet 255.255.255.0

Gateway 0.0.0.0

DNS: <leave empty>

Follow the instructions to setup your ethernet card connected printer with the following configuration:

IP 192.168.2.2

Subnet 255.255.255.0

Gateway 0.0.0.0

Now add the new printer by Control Panel > Printers and Faxes, choose Local Printer but do not click the attached directly button.

Click next and then create your own port at the bottom by chooing TCP/IP.

Click next and just type 192.168.2.2 in the IP Address box.

Click next and you should instanty be shown the new printer successful install page – click Finish to Finish.

Thats the best way, you can then share those printers on your locally connected network. The serial pors for printers are useless and parallel port switch boxes are just very inconvenient on a network with more than one PC or laptop.

Mac OpenOffice Problems

Hi all,

Not wanting to buy Microsoft Office and having to use .doc files – I have OpenOffice 2.3 Aqua on my Mac.

It usually takes a while to load which is annoying – so after some searching I found a way to speed it up.

1) As superuser run the following :


sudo su -

nano /Applications/OpenOffice.org\ 2.3.app/Contents/MacOS/sofficerc

simply change 'Logo=1' to 'Logo=0'

To enhance the usability there are some more instructions at the link below:

Right Click Kills Mac OS X Finder

Okay so you are working away day after day and every now and then when you right click on a folder or file all your Finder windows just up and disappear.

Oh that’s a bother but never-mind it will be back in a minute…… or two.

Basically its the contextual menu folder that has an issue and more specifically the StuffItCM.plugin (from stuffit & co).

Simple solution is to :

Go to “~/Library/Contextual Menu Items” or “/Macintosh_HD/Library/Contextual Menu Items” and delete the file StuffItCM.plugin.

Maybe a reboot or logout/login just to be safe and also empty your trash for good!

et voila

Let me know if this works for you with a quick thanks.

I found this out from the thread here.

N95 Hard Reset Code *#7780#

If like me you have constant issues with your Nokia N95 – and the factory default setting does nothing, you can always try the hard code *#7780#.

Always backup your data first and regularly before messing with any settings !

Nokia N95 + Mac PowerBook

So you just got your new Nokia N95 and not even the techies at the ISP know how to use it.

What do you do?

Hit the Google Hut!!

So in my case i needed to get the modem script for my Macintosh laptop. I found this a great resource

http://felipe-alfaro.org/blog/2007/02/11/mac-os-x-bluetooth-and-nokia-umts-phones/

You must basically complete the following steps, with a little tweaking along the way to get things right for you.

1 – download and install the modem scripts into /Library/Modem Scripts/
2 – pair the phone and laptop
3 – configure the new phone bluetooth device through System Preferences/Bluetooth/Devices/Configure
4 – these settings worked for me on t-mobile (more accurate instructions at the link above), GPRS ->> user == user, password == pass, GPRS CID String == general.t-mobile.uk, Modem Script == Nokia 3G CID1

if you need further instructions check out that link, also attached a document from a helpful chap at T-Mobile

PXE Network Installations using Linux Servers

Hi again,

I’ve been busy testing out the way you can install an operating system, mainly Linux at this stage, directly from booting up your computer/server.

Server

  • You need a server operating system, in this case I am using Fedora Core 6 – but I have also applied the principles to Ubuntu, capable of running DHCP and TFTP services.
  • Enough hard drive space for the server operating system and also enough space to store the contents of the downloaded discs.

Client

  • The minimum requirement is a network card, NIC, with a network boot ROM on and a hard drive with enough space for an operting sytstem of cours.

General Connections

  • A network switch or hub is recommended, although a cross-over cable would suffice (and proably be fairly quick).

So, now onto the specific server requirements…

  1. Download Fedora Core 6 here.
  2. Burn the discs and install a minimum setup – this should help.
  3. create a folder /Fedora and copy the dics 1 contents into this folder.
  4. copy the contents of the directories Fedora/RPMS from each additional disc into the newly created folder /Fedora/RPMS/ (no need to overwrite anything).
  5. make sure you have system-config-netboot/httpd/dhcp/tftp-server installed on the server system. use the command.

yum install -y system-config-netboot httpd dhcp tftp-server

DHCP.conf configuration/setup

  • Supply information so that the connecting machines know the network details as to whewre to find the operating system installlation files. Soedit the config file using:

nano /etc/dhcp.conf

A basic configuration follows:

ddns-update-style none;
option domain-name-servers 192.168.0.1;
default-lease-time 86400;
max-lease-time 604800;
authoritative;
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.200 192.168.0.229;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.0.255;
option routers 192.168.0.1;
filename “pxelinux.0”;
next-server 192.168.0.100;
}

An explanation,taken from the source of this dhcp tutorial found here, follows:
I explain the configuration options here:
* ddns-update-style: You can tell the DHCP server to update a DNS server if the IP address of a server in your LAN has changed (because it has been assigned a different IP by DHCP). As we do not run servers in our LAN or always give them static IP addresses (which is a good idea for servers...) we don't want to update DNS records so we set this to none.
* option domain-name-servers: This tells the DHCP server which DNS servers it should assign to a client. You can specify more than one DNS server here, seperated by commas.
* default-lease-time, max-lease-time: A client can tell the DHCP server for how long it would like to get an IP address. If it doesn't do this, the server assigns an IP address for default-lease-time seconds; if it does, the server grants the requested time, but only up to max-lease-time seconds.
* authoritative: If this is not set this means that if a client requests an address that the server knows nothing about and the address is incorrect for that network segment, the server will _not_ send a DHCPNAK (which tells the client it should stop using the address.) We don't want this so we set authoritative.
* subnet: The subnet to use.
* netmask: The netmask to use.
* range: Tells the DHCP server from which range it can assign IP addresses to clients. In our example it's from 192.168.0.200 to 192.168.0.229 (30 IP addresses).
* option broadcast-address: The broadcast address to use.
* option routers: Tells the DHCP server the gateway address it should assign to requesting clients. In our case the gateway is 192.168.0.1.

The last two lines I have added myself,
filename "pxelinux.0";
next-server 192.168.0.100;

this tells the network installation machine to load the “pxelinux.0” image from the server 192.168.0.100.

Start the DHCP server using:

/etc/init.d/dhcpd start

Hopefully, no errors. now to ensure the dhcp server always starts after rebooting run:

chkconfig dhcpd on

Configure WebSite Alias

The install requires a running web-server from which the files are transferred to the new installation machine.

Therefore, we add an alias to the web-server, which we will call /fedora. The alias will point to the physical directory /Fedora. Open the web-server configuration file using:

nano /etc/httpd/conf/httpd.conf

and add the directory with its alias to the end of the file:

Allow from 192.168.0.0/24
AllowOverride None

alias /fedora /Fedora

Network Boot Configuration/Setup

To install our initial netboot install run:

system-config-netboot

and choose “Network Install”.

picture-3.png

Now add the name of your install – say “Fedora Core 6”.

Add the location of the install files, using 192.168.0.100/24 we add the line:

192.168.0.100/fedora

The location of our kickstart file will be at 192.168.0.100/fedora/ks.cfg

——————————————————————-

Hopefully, that should just about get you going with a great PXE nertwork install.

Please let me know if I can improve this tutorial or adapt it to suit your needs.

Easy Linux Encoding (FFMPEG)

Hi,

After much trying and testing I have found a viable solution to encoding movies using ffmpeg.

Simply put:


ffmpeg -i /movies/film.mp4 -b 800k -vcodec xvid -acodec mp3 -ab 192 -ar 48000 -vol 1500 /movies/film.avi -y

Breaking it down:

-i /movies/film.mp4: this specifies the input file
-b 800k: this sets the film bit rate (basically the quality of the output)
-vcodec xvid: uses the xvid codec to encode the video file (Linux users install xvidcore)
-acodec mp3: uses the popular mp3 codec to encode audio
-ab 192: sets a good scope for audio quality (sometimes depends on input bit rate)
-ar 48000: sets the highest quality sample rate (ensures quality audio)
-vol 1500: sets the volume (in case the sound is bad)
/movies/film.avi: the output file
-y: necessary if you want to overwrite without existing files without prompts (useful when testing)

Optional

-t 30: this allows only 30 seconds (variable in seconds) of encoding (so you don't have to wait for the whole film to encode before testing it works as expected)

Bash Script for multiple file encoding

If you want to encode multiple files using a for loop the code below will help:

N.B. assuming you are i the directory where your video files are stored.


for N in *
do
ffmpeg -i $N -b 800k -vcodec xvid -acodec mp3 -ab 44100 -ar 128 /videos/$N
done

there it is!

leave a comment if you need help

cheers

Unlocking Nokia 6630 (from Vodafone)

Hello all,

This is for those of us with the excellent Nokia 6630 mobile phone, who want to change Networks to find a better offer – but keep the benefits of the great Symbian handset.

If like me you sign up for an amazing deal with Virgin or T-Mobile and try to insert your new card into your existing 6630 handset – you are no doubt greeted with a “Sim Restricted” message.

No doubt, and like me, most users with a 3G Nokia 6630 will be on the Vodafone network. You may have also scoured the many unlocking website, only to be told that “these phones cannot be unlocked”……

It is in my personal opinion, and first hand experience, that the people who tell you this do not actually own a Nokia 6630 of their own!!

I can 100% guarantee that it is possible to unlock these DCT5 phones for use with any network.

I lay out the instructions for you, and advise that the overall process took me just less than a week and cost me £0.00p yes – it is free!!!:

  1. Make a note of you IMEI number (press *#06#).
  2. From your mobile handset call 191.
  3. Inform the operator that you have had your phone for approximately 18 months (very important as phones under a year old incur an unlocking fee).
  4. Place a request for unlocking the phone with the operator.
  5. Wait a few days (or call each day) and check the unlock status for your phone.
  6. Make a note of the unlock code (when available) – it will be something like #pw+xxxxxxxxxxxxxxx+x#
    1. + is found by pressing * twice.
    2. p is found by pressing * three times.
    3. w is found by pressing * four times.
  7. Make a note of your PIN number.
  8. Enter the unlock code (#pw+xxxxxxxxxxxxxxx+1x#) where x represents a number.
  9. Your phone should now say Restriction Off or something similar.
  10. That’s it!! You can freely use your new sim card.

I am now very happily using my free minutes with a great deal from Virgin/T-Mobile and Telewest.

All the best
