On 21 March, 2001, you quoted Dale Mentzer as having written a couple of days earlier as follows: DM > Even if you don't use LSPPP with it's dynamic DNS addressing, you can DM > always use any other servers DNS numbers.

Does this kind of trick work to fool your ISP only if it *does not* support dynamic DNS addressing? BTW, I would hesitate to conduct any experiments along these lines for fear that I might become identified as an aspiring would-be hacker or spammer. >> With >> LSPPP it is not necessary to indicate the DNS numbers if the ISP supports >> dynamic DNS addressing.

When > you use BOOTP with EPPPD, you put DNS numbers in PPPDRC.CFG and > myip=bootp in WATTCP.CFG The first line of all my WATTCP.CFGs looks like this: include=path.cfg Below this line I add other data which I believe to be either needed or at least somewhat helpful to the particular application I am running. Sometimes I might specify a named directory for "path.cfg" and sometimes I use relative path names. I have discovered that sometimes some applications will not find "path.cfg" unless a copy of this file resides in the very same directory as the application, no matter where WATTCP.CFG says to look for it. "unable to locate path.cfg" is a typical error message. The remedy is simply to locate "path.cfg" in the same directory as the app. The files I use for holding the arguments used to load EPPPD are batch files similar to the ones recently posted by Alejandro Lieber and myself. I programmed my batch files according to the models used by John Lewis of the VE3LGS Home Page, http://members.kingston.net/lewis >> > In order to use real or server-side BOOTP, you have to use PPPD. >> Is PPPD the same as EPPPD? > Not quite.

I did go there and I found a very enlightening discussion on this topic.

Someone on this list (I forgot who) said it was necessary because Arachne is hard-coded for EPPPD. Another question for you: Of the four environmental variables set by IP-UP.BAT, one is called "peermru" and it is set equal to a number. Do you know what this environmental variable is for, and how it may be used by the program? I thank you very much for your replies and comments. Regards, Sam Heywood
