Simple, you enable bluetooth on both your mobile phone and laptop and dialup to your machine. After moments, the connection is established and voila, you can even login to your machine via remote desktop !! Here you are, is that firewall enabled? Everything OK and cheap, especially if you have two sim cards from the same provider. Drawback, a bit slow connection (9,6kbps without GPRS, not tested with GPRS yet)

THE FOLLOWING WERE ACCOMPLISHED WITH WINDOWS XP, BOTH THE SERVER AND CLIENT SIDE, Windows 2003 + IVT BlueSoleil = BLUE SCREEN.

DEVICES USED: Motorola L7-imode, P900 and PDAs with Windows Mobile 5, IPAQ 514 NOT WORKING (Dial Up Networking not accessible with factory firmware)

SERVER SIDE

1) Enable bluetooth to both laptop (just insert the Bluetooth USB Dongle to a free USB port) and mobile phone

2) Download the neat program for bluetooth drivers and connection tools, IVT BlueSoleil

(I didn’t succedd setting up the server using the default WinXP bluetooth drivers, they work for client side though)

3) Open BlueSoleil. A pop up at the right down corner of the screen indicates that “Bluetooth started”, otherwise there is a problem with the drivers so check that all OK. If nothing happens, uninstall and reinstall BlueSoleil.

4) “My Bluetooth” -> “Bluetooth Device Discovery”

Your phone should be found, otherwise bluetooth is not enabled on your phone

5) Right click your phone -> “Pair” -> choose a password and put the same on the mobile. Now on BlueSoleil a red tick on mobile phone indicates that pairing is OK.

6) “My Bluetooth” -> “Bluetooth Service Discovery”

7) Double click “Bluetooth Dial-Up Networking Service” (it must have a yellow line around it, otherwise your mobile is not compatible)

8) If you are asked whether to make a permanent port mapping answer YES. So, you see the image1. Notice the dotted green line between the “Sun” (laptop) and L7-imode (it indicated that connection is established) and the red tick on L7-imode left down icon corner.

In case you are on client side, you fill in username/password and telephone number, click Dial and if everything is OK, after a few moments you join your home network. (Leave the other settings at their default values - Just make sure that “Wait for dial tone before dialing” is enabled at modem properties (”Control Panel” -> “Phone and Modem Options” -> “Modems” -> “Bluetooth DUN Modem” (DUN aka Dial Up Networking) -> “Properties” -> “Modem” ).

9) Assure that the mobile phone’s modem ic correctly recognized and ready to accept/make calls.

“Control Panel” -> “Phone and Modem Options” -> “Modems” -> “Bluetooth DUN Modem” -> “Properties” -> “Diagnostics”

You see the following image2

Press “Query Modem”

In BlueSolleil appears again the green line and a popup ” Connecting… Connected (COM XX)” image3 .This popup is critical, it indicates that the mobile’s modem is correctly recognized and communicates well with BlueSoleil

So, query is successful and the following appears image4 . Notice that in the second line the mobile is correctly recognized (there are cases where the modem responds to the query but the exact model is not recognized and the whole attempt finally fails. In that case go back to 6 - 7 - 8 - 9

10) So, lets setup the incoming connection at networks connections

“Start” -> “Settings” -> “Open Network Connections”

Delete any DUN inbound connections. In order to establish an DUN inbound connection using mobile’s modem it is CRITICAL that the connection is created from scratch and there is any previous inbound connection (also inactive ones). So, DELETE any inbound connection. THIS STEP MUST BE MADE EVERY TIME

-> “Create a new connection” -> “Set up an advanced connection” -> “Accept incoming connections” -> at “Devices for incoming connections” choose “Bluetooth DUN Modem” -> “Do not allow virtual private connections” -> at “User permissions” just choose a user or add a new one and assign a password to it (this user is not a common windows user, it is just for the dialup session) -> at “Networking software, select “Properties” on “Internet Protocol (TCP/IP)” and just assign the appropriate settings/ip.

That’s it :) Notice the popup of BlueSoleil indicating “Connected (COM XX)” when you access “Devices for incoming connections”

In BlueSoleil the green dotted line appears and indicates that the server is ready to accept incoming connections :)

It looks like this image3

CLIENT SIDE

Just follow STEPS 1-8

FINALLY, the connection is established and you are connected to your home network. With maximum security of course.

CONGRATULATIONS

Lets say that we want to connect to the vpn server test.no-ip.biz via a mikrotik vpn client interface named pptp-out1. The problem with mikrotik is that it accepts the domain name and resolves it but only for the first time. So, if the server changes ip, the vpn connection is history. So we want a slave to check when the server changes ip and pass it to vpn client interface.

So, here is the slave :)

Just go System -> Scripts -> Add and give the following code

Source

(be sure to include the ” : ” at the beginning of each line, except if you want to start scratching your head wondering what the $#%@ is wrong - I promise to write a more detailed guide to mikrotik scripting another time)

After finishing check that the script runs fine by hitting run script and that the run counter increases by 1.

So, now its time to add it to the scheduler.

System -> Scheduler ->Add

Give a name, start date, start time and set the interval to a frequency depending on the severity of the link (the highest, the greatest) (a zero interval mean no scheduling - just 1 execution and thats all)

On event give :

otherwise the scheduler goes to Bahamas for holidays :P

So simple… :)

I’m Thanasis, code name “tweety” ;) , I’m from Greece and this is my tiny tiny tiny www space. Welcome and relax (especially if you have a 22” tft ;) ) or just pick up the info you are searching for and good luck… This blog will be mainly about computer science (you know all that boring windows, network and brilliant linux stuff), everyday problems I find and their solutions - unless it isn’t my lucky day ! And of course nothing about the weather, how ugly our world is and if aliens live among us :D

So, here we are. In this blog, there are hints about wireless networks everywhere (more will be added soon). Yes, I’m a member of Patras Wireless Metropolitan Network (aka PWMN). The consept is to provide wireless networking to Patras, Patras suburbs, near villages, towns, provinces and finally Athens. Athens as you probably don’t know has one of the greatest wireless networks in the world, Athens Wireless Metropolitan Network (aka AWMN) . We have about 40 backbone nodes, 100 simple nodes (active) and 170 forums users with new wireless users coming everyday and helping to expand our network. The whole network has a voluntary character, everyone helps whatever and whenever wants - it is like an internet micrography where the backbone routers are base stations - routers, which are provided by people who want to contribute their knowledge, free time, equipment and money 24/7 TOTALLY FREE to the community. That’s the magic of the story… Of course it will be better if the local municipality helped but we live in Greece, “these things” move rather slowly :P

So for the time being just take a look at the photos, the gallery WPG2 and the links to learn more about our community
