 Political Chat On The Internet

Before you do anything, please read the instructions that came with your router.  I cannot stress this enough.

We are going to start by obtaining some information that you will need, in order to configure your settings.  Get a pencil and paper and write these items down:

Computer #1 (This is the computer that your Router is connected to).                                      
1.  Router Assigned IP#_____________________                        
2.  DNS Span_____________________ to ____________________
3.  Internet IP#_____________________
4.  DCC Port #s____________________ to ____________________

Computer #2 Router Assigned IP#_____________________
Computer #3 Router Assigned IP#_____________________  

You will need to make an entry for each computer on your Network, as the Router Assigned IP# will be different for each computer.

FIND OUT WHAT YOUR ROUTER IP, AND DNS  SPAN ARE

Get on the computer your Router is connected to (this will be Computer #1).  Go to START, then RUN.  Type in CMD   and enter.  When the Dos Popup appears type in ..    ipconfig/all   and enter

You will see a list of numbers.  Look for the entry called "IP Address".  Write that number down on the Router Assigned IP# line on your list.  The number will probably look something like:  192.168.1.100

Now look for an entry called "DNS Servers".  Write down the two numbers of the  DNS Servers (example 68.13.16.25  and 68.13.16.30) , on the  DNS Span line, of your list.

If you have other computers, you will need to repeat this procedure on each computer on the Network.  The only thing that will change, are the last three digits of the Router Assigned IP#, for each computer (example 102, 103 etc)..

Note:  The Router Assigned IP#  is not the same, as the IP address that your Internet Provider has assigned to you.

FIND THE IP ADDRESS YOUR INTERNET PROVIDER HAS ASSIGNED TO YOU

Click HERE to go to a website that will tell you what the IP#, that your Internet Provider assigned to you, is.

Look for the numerical address (example)    IP-Address:  24.164.150.219   
Write this number as the Internet IP# on your list.

SELECT YOUR DCC PORT NUMBERS

You will need to select a range of port numbers to DCC on.  Here is the information you will need in order to make this decision:

The port ranges need to be in a very high numbered range. Do not pick port numbers below 1024 (i.e.  1 to 1023), as this could cause major problems with other protocols (FTP, HTTP, SSH, SMB/CIFS, NFS, and hundreds of others). Stick to port numbers above 40000, and do not exceed 65534.  For example you could use 47000 to 47010, or 50000 to 50010.

How many Ports?  Ten Ports are sufficient unless you will be sending and receiving more than 10 DCC’s at a time. 

When you have decided what the Port numbers will be, write them down next to DCC Port #s on your list.  We now have the information we need, and can move on to actually making the changes that will enable to you DCC successfully.

SET UP PORT FORWARDING

Make sure you are working on Computer #1 .. the one  that your Router is connected to.  These changes will be made on your Router Configuration and MUST be done on the computer that your Router is connected to.

Open up a browser and type 192.168.1.1 in the address bar, and click GO.    A Password request Popup will open.  You may have not already set up a User Name and Password.  If not, type in   admin for the User Name, and leave the Password empty; then enter.  You are now at the Wireless  Configuration Setup Page. 

Look at the tabs across the top, and click on the tab that says APPLICATIONS & GAMING. 


Exhibit A

On the next line, click on the tab called Port Range Forward. This is where you will be adding two entries for each computer on your Network:    
     1)   DCC, which will enable DCC receive 
     2)  mIRC, which will allow identd to work, and will also enable DCC send.


Exhibit B

Port Range for the DCC line, will be the DCC Port#s on your list. 
Port Range for mIRC line will be 113  (start and end).
Protocol - Select BOTH
IP Address - This is the Router Assigned IP# that you wrote down for each computer on your Network.  In this example, the last three digits changed for each computer.  
Enable each entry.

When you are finished click SAVE CHANGES.  Before you leave, review each line for errors and omissions.

Note:  One other thing you might check while you are in here, is the version number of your Router software.  I had one person tell me that the reason identd would not work for them, was because they had to upgrade their software to a newer version.  So if you get to the end of this and still cannot get identd to work .. you may want to consider that possibility. Call your Router Mfg. and they can help you update your software.

REQUIRED CHANGES IN mIRC

Open up mIRC and then disconnect from the server (changes should be made while disconnected).  Open up mIRC Options (Alt+O) .. Click on the Connect tab,  then the Local Info tab. 


Exhibit C

Local Host:  Leave empty (mIRC will fill this in for you)
IP Address:  Type in the Internet IP# from your notes.
On Connect Always Get ..  Untick  both Local Host and IP Address.  Both must
be Unchecked.
Lookup Method:    Tick the  Server  option.

Click OK,  and close. 

CHANGE THE DCC PORT NUMBERS IN mIRC

You need to make mIRC match the port numbers you entered in Port Forwarding.  In this example, I assigned 50000 to 50010 in Port Forwarding.  Depending on which version of mIRC you are using, you will find the Port Numbers in  mIRC Options (Alt/O), then click on the Connect tab, and then click on the Options tab.
Click the Advanced button. Type in DCC Port#s from your list.  Check the box that says "Use Random ports".  Click OK twice  to close.


Exhibit D

Note:  If you are using an older version of mIRC, the place where you add DCC Ports is different.  Open up mIRC Options (Alt/O), then click  DCC tab, then the Options tab. 

SUDDENLY UNABLE TO DCC FOR UNEXPLAINED REASON

For some reason, every so often I will suddenly be unable to DCC.  I am on the SAME computer, I haven't change a thing, and it suddenly refuses to DCC.

I have found that when this happens it might have been due to a hard shutdown, maybe you were being packeted by someone, a power surge, blue screen of death ??  Something along those lines.

Possible solutions:

1)  If this happens to you, the first thing you need to check is your mIRC client.  Go to  Options --> Connect --> Local Info.  Check to make sure that mIRC did not revert back to using the bouncer ip address.  If it did, you will need to change it back to your real Internet IP#.  I don't know why this happens, but it does occasionally.  If this does not fix things try the next solution.

2)  Unplug your modem, and then your router.  Plug the modem back in and wait about 1 minute .. then plug your router back in.  Now try to DCC.  This usually fixes it for me.

There are some EXCEPTIONS that I want to mention:

I can only DCC over computers that are HARD WIRED to the router.  My other computers, which operate solely on the wireless card cannot DCC, no matter what I do.  The bottom line is this:  You will probably not be able to run identd or be able to to DCC, from any computer that is solely connected to the internet via the wireless  card.

Best of luck with your DCC problems.  Hope this helps.  

Sincerely,

CometBaby
