Your soothing techie is also a smooth talker. He's full of bologna (or is it blarney).

 

You didn't say wht computer or software version you're using, but I'm going to assume it hasn't been updated for a while since ConfigPPP and MacTCP have gone the way of bell-bottoms (oh wait, those are back in style).

 

Let's see if I can do this ConfigPPP from memory....(scratch head, rub chin...)

 

There are two parts to your problem:

 

Part one: setup ConfigPPP to dial into and authenticate two different ISP's. This shouldn't be too bad. You need to collect some info from your ISP's:

 

You need to find out if you Authentication user name and password are the same as your "email" user name and password. They may not be, and if they're NOT, you need to find out.

 

You need to ask for the domain names and IP addresses for the ISP's Domain Name Servers. For example, this is my DNS (Domain Name Server),

 

interaccess.com 198.80.0.6

 

Each ISP will give you at least one combination domain/IP setting (maybe more).

 

And the last questions you need to ask are the gateway IP, and how are IP addresses assigned (manually, dynamically, server).

 

Whew! Too much information

 

-----------------------------------------------------------------

 

Now open ConfigPPP.

 

Select CONFIG for the current SERVER, and the configuration window will show you:

 

Port Speed

Flow Control

Phone Number

Modem Init (copy all these down and close the window)

 

 

Now select NEW and name it something like "Dial Into Iol" and click OK. The PPP Server should now say "Dial Into Iol". If not, use the popup window to select it.

 

Select CONFIG and enter the Port Speed, Flow Control, and Modem Init that you copied earlier. Enter Iol's dial in phone number. In this same window, in the lower left, is the Authentication button -- hit it!

 

For your iol.ie account, enter your Authentication user name and password then OK to close the window, then click DONE to close the Configuration window.

 

Repeat the process for indigo.ie. Don't worry that you're entering the same Port Speed, Flow Control, and Modem Init as iol.ie. Odds are it's ok.

 

When you're done, you'll have two new server settings in ConfigPPP (as of this point, we don't care about any of the older servers).

 

Close ConfigPPP and open MacTCP.

 

Now you need to make a decision: Which IPS has the fastest, more reliable connections? I'll call him Good-ISP ;)

 

In MacTCP select MORE.

 

Before changing anything, copy down the current settings:

 

Gateway IP, whether the MANUAL, DYNAMIC, or SERVER button is selected, and all the DNS domain/IP combination (noting which is DEFAULT).

 

Time to make some changes.

 

--------------------------------------------------------

 

In the upper left, select MANUAL. Enter the gateway IP of the Good-ISP in the lower left.

 

In the lower right enter the domain name/IP combination for the DNS of the Good-ISP Select the adjacent DEFAULT button.

 

Next enter the domain name/IP combination of the DNS for the _other_ ISP (don't select DEFAULT).

 

If there are other combinations, enter them in any order you wish.

 

Ok, almost done.

 

Back in the upper left hand corner switch from MANUAL to whatever system the Good-ISP uses (probably DYNAMICALLY).

 

Close the settings window. You are now looking at MacTCP, and hopefully there is an icon within the TCP window that says "PPP". Select it and close MacTCP, and RESTART the computer.

------------------------------------------

Chime...Welcome to Macintosh... progression of icons...load Finder...all

done...

------------------------------------------

 

All-righty-then...

 

Open ConfigPPP and choose the Good-ISP server and hit the OPEN button (I hope to God you can select the Open button, or I'm in trouble)

 

If all is good, you should be all logged into Good-ISP. Check mail, get news, browse web.

 

Everything OK? No Server can't be found errors? No (I hope) Good. Disconnect and repeat with the other IPS.

 

It should work also.

 

 

Here's the caveat: Regardless of which ISP you log into, you will always be using the Domain Name Server of the Good-ISP because we choose him as DEFAULT. If that server should go down, TCP will switch to the next DNS on the list. This would slow things down a little, but it's really only a problem id Good-ISP DNS goes down.

 

If you have any questions, if the control panels look different that I described, please email me and we'll figure it out.

 

Good Luck,

Michael
