Protect Yourself When Using P2P

Although there is no proven way to completely protect yourself from the money hungry bastards that want to limit and control the P2P networks, there are some ways that you can protect yourself.

First of all, don’t share your entire hard drives. I have seen people sharing their entire C: drive. (Windows users of course)

Second, use some sort of program that will block connections to and from servers and clients that are known as fake, bad, corrupt, or just some unknown that seem suspicious. Two programs I know of are… Protowall and PeerGuardian.

After you have an IP Blocking Program, you have to keep it updated. There are probably many more, but I use Blocklist Manager which can update block lists for eMule, PeerGuardian, Protowall and many more.

Third, if you are sharing lots of files, DON’T leave your P2P program running 24/7 if your not downloading anything!

Linksys PAP2 Phone Adapter

I found some information on this topic by searching around the internet, I have tried this information and it works great for me. Please note that I have not created any of this content, I am just mirroring it.

First things first –

Download: SP2KPAP2.zip
Download: PAP2SP2K.zip

DO NOT CONNECT THE PAP2 TO ANY NETWORK WITH INTERNET ACCESS until directed. The unit will attempt to connect to a Vonage TFTP server on power-up and update firmware without your intervention. If this happens the unit could become a brick. Keep the unit isolated until these parameters are changed and you are directed to connect the unit to the net and/or public internet.

New Unit –
A new “out of the box” pap2 will not have ANY network parameters setup (IP Address, IP mask, gateway, etc). First, configure the pap2 via a touch-tone phone with minimal IP information that will permit later access via your web browser.

Review Chapter 4 of the Linksys pap2 Installation and Troubleshooting Guide.

Connect a standard touch-tone phone to port #1 and make the following changes:
a) Disable DHCP – ‘****’, ‘101#’, ‘0#’, ‘1’ hang-up
b) Set Static IP Address – ‘****’, ‘111#’, ‘192*168*2*10#’, ‘1’ hang-up
c) Set Network Mask – ‘****’, ‘121#’, ‘255*255*255*0#’, ‘1’ hang-up
d) Set Gateway Address – ‘****’, ‘131#’, ‘192*168*2*20#’, ‘1’ hang-up

The following steps have set the pap2 IP address to 192.168.2.10, mask 255.255.255.0 & gateway of 192.168.2.20. This document will utilize these addresses later. If your network uses different address/mask/gateway adjust accordingly.

Reboot the pap2 and use the phone to confirm the changes were saved. You can also check around to determine current firmware version, MAC address, etc. You don’t need them for later steps, but feel free to check them out. NOTE: you will be unable to enter the ADMIN account at this time (unit is locked).

Change your DNS addresses –
Modify the DNS (Primary & Secondary) to match your ISP’s DNS values. It may be necessary to change these at a later date to ones associated with the VoIP provider.

Isolate your network from internet –
For this next sequence disconnect your LAN from access to the public internet. Also, DO NOT ATTEMPT to update firmware via a wireless connection – bad results. Hardwired connects only!

Install tftp server utility –
Included on the CD-ROM is a free tftp server utility – tftp-desktop-free ver 2.5. Suggest you use this utility because you can monitor the firmware download/update process. This can be downloaded from www.download.com, search for tftp. While this utility is free, it’s possible it can only be used for 30 days. You may need to get a “fresh” download.

NOTE: The tftp utility installs nicely under WinXP and creates a directory in /Program Files/TFTP Desktop . You will need to know this in order to copy the firmware images to that area and rename the files.
ALSO: The utility does NOT start/run automatically when your system is booted. It is necessary to click on the ICON to start the utility.

Uncompress/Copy Firmware Image Files –
Two Firmware image files need to be unzipped, renamed and placed in the tftp default directory, which is /Program Files/TFTP Desktop. Uncompress the following files:
pap2SP2K.zip and SP2Kpap2.zip. After the files are uncompress into the tftp default directory it is CRITICAL to RENAME the file to correct a naming error. The files must be renamed to add a ‘-‘ as follows: pap2SP2K.bin to pap2-SP2K.bin and SP2Kpap2.bin to SP2K-pap2.bin

Next, if your PC/Laptop does not have a static IP address you should assign one at this time. While not absolutely necessary to have a static IP address, your IP address must be known (and does not change) in order for the pap2 to find the tftp server and thus the firmware to be downloaded. For purposes of this example the tftp server PC has an IP address of 192.168.2.110, mask 255.255.255.0

Connect the pap2 ethernet port to your isolated network. Remember, you don’t want the pap2 to get to the internet – not yet!

Next, ping the pap2 device to make sure your network connection is working.
PING 192.168.2.10

START OF FIRMWARE UPDATE –

Open a browser and enter the IP address of the pap2:
»192.168.2.10

You should have opened a Linksys pap2 configuration page on the INFO tab. Select the SYSTEM tab. Enter an USER password of 1234 and at the bottom of the page select SAVE SETTINGS.

Now refresh your link and you should be prompted with a login screen.
Enter a User Name of USER , password = 1234
Keep this browser page open, but shift it down to the lower right section of your display.

Next, start the tftp server utility and position the window in the upper left section of your screen. This is to permit monitoring the firmware download process.

Next, return to the open browser page and position the open window such that you can continue to monitor the tftp desktop window – keep at least 1/3 of that window visable.

Update the browser address line and enter the following: »192.168.2.10/upgrade?tftp://192.···SP2K.bin
Monitor the tftp window and you should see a progress bar indicate the download status.
At this time the Power LED should turn RED.
Wait at least 1 or 2 minutes after the status shows complete – do not interrupt it.

Once RED, update the browser address to your pap2. (our IP in this example is 192.168.2.10) login using user account USER , password = 1234

At this point you should now see a Sipura Phone Adapter Configuration screen.

Click the “admin login” link near the top-right.
Click the “advanced” link near the top-right.
Click the PROVISIONING tab and set PROVISION ENABLE=NO.
Click SUBMIT ALL CHANGES.

At this point you might get an “unable to display” page on your open browser page – don’t worry about it – leave it as is.

Next, update the browser address line and enter the following: »192.168.2.10/upgrade?tftp://192.168.2.110/ SP2K-pap2.bin [ver 3.1.3]
Alternate version
»192.168.2.10/upgrade?tftp://192.168.2.110/ pap2-BIN-03-01-06-ls.bin [ver 3.1.6]
* * * * *
Again, monitor the tftp window and you should see a progress bar indicate the download status. Wait at least 1 or 2 minutes after the status shows complete – do not interrupt it.

The Cisco/Linksys pap2 will eventually reboot (2 solid blue LEDs) (BE PATIENT)

DONE – The firmware update/unlock is now complete.

When you login to the pap2 unit you will again have a Linksys pap2 configuration screen and you should be able to access the ADMIN LOGIN link without a password.

The unit is now unlocked and can be configured for various VoIP services. You can now safely connect the pap2 unit to a network exposed to the internet. HOWEVER – never attempt to do a FACTORY RESET – or your unit may be locked again to Vonage and might not be unlockable a second time. Still working on it.

Getting Started with Bittorrent

So you want to download files from sites that are using Bittorrent? But have no idea how to start? No problem, I am going to walk you through downloading files using a Bittorrent client.

First, you are going to need a piece of software called a Bittorrent client. There are quite a few programs that will do this task, but I like using uTorrent, and thats what I’m going to walk you through.

Get uTorrent by clicking here [Link: http://www.utorrent.com/download.php ]. I recommend that you download the Installation Program version, as you can easily remove it later on, if you don’t have a use for it.

When the file is done downloading, double click to open it. Choose your language from the list and click OK.

Click Next on the Welcome Screen. The default Destination Folder is best in most cases, click Next at the bottom. The installer will now ask you what to call the start menu folder, click Install at the bottom, as the default is fine.

When it is done, click Finish at the bottom. Lets configure the client now.

You can delete the file that you downloaded if you wish, then go to Start -> Programs -> uTorrent and run uTorrent.

The welcome message will display, you can click on No, because we already have a shortcut on the start menu. uTorrent will now ask if you wish for it to be the default application for .torrent files. Go ahead and click Yes, this will make your life much easier.

The next screen is where things get a little confusing. For uTorrent to download files more efficiently you have to forward a port in your router, it can be any number you choose at the bottom. Default is 32459. I will have to let you refer to your routers manual if you have a router.

Click Run speed test at button and choose the best speed for what the site returns to you. Then, click Use Selected Settings at the bottom of the dialog.

Now you have completed the install of uTorrent.

Now the easiest way to download files, is to find a tracker website, and follow their way to download the .torrent files, when your browser goes to download the file, uTorrent will open the file and begin.

Incorrect Times on Mobile Devices

Had some problems with the time change here at work, seems that most websites left out a very important detail as to what gets upgraded, what order, and how so when using mobile services with Microsoft Exchange.

The devices that I am dealing with are the:

Palm Treo with GoodLink
Blackberry Devices with Enterprise Management

Running on these servers, you should also have the Microsoft Exchange Management Tools. I could find no place that mentioned these tools, after they have been installed, they are virtually untouched. You have to upgrade the installed tools to the same version as the Exchange server itself, then Install the CDO patch against the TOOLS. All of the sites that I have found, talk about applying the CDO patch to the Exchange server itself.

Links: Exchange 2003 Service Pack 1
Links: Exchange 2003 Service Pack 2

Here is the problem I was having…

If you create an appointment from 1:00PM to 2:00PM (or other times, this is just an example) using Outlook from your client, the appointment times are correct, even on the device it says 1:00 to 2:00. But, if you create an appointment using the mobile device, say at 2:00 to 3:00, and then look inside outlook, the appointment will say 3:00 to 4:00, which as you just created the appointment, already know this is incorrect.

All of our mobile devices experienced this problem. GoodLink Palms, and Blackberry Devices. After installing the Exchange SP2 upgrade on the server not even running Exchange, and then the CDO patch on top of that, these problems went away.
