Subject: Re: Mersenne: Prime95 shutdown mystery.
Several folks have responded privately about my problem with Prime95
crashing, much thanks. All recommended:
>In prime.ini, change/add the line:
>
>UseHTTP=1
Having made thsi change, the program now runs, but I can't get any response
from PrimeNet other than:
ERROR 2250: Server Unavailable.
And a referral to a faq that recommends the same change.
Any ideas about what I should try next?

Since it seems to be working OK for me, it's possible you have a name
lookup problem.
If you have an entry for entropia.com in your hosts file (somewhere
under the Windows directory, or in /etc on a linux system) try
removing it, then try again. If you don't have an entry for
entropia.com in your hosts file, or the above fix doesn't work, try
adding the following line to it:
216.120.70.80 entropia.com
(Funnily enough the format is the same for both windoze & linux!!)
If it _still_ doesn't work, try tracing your route to 216.120.70.80
using the traceroute tool in linux, or a suitable Windows utility - I
use & reccomend the freeware utility "CyberKit" which can be freely
downloaded from numerous places. The distribution file I'm using is
just under 1MB in size, but I probably don't have the latest version.
You may find that you are being blocked at a firewall, at least
traceroute will identify if this is the cause of your problem and
also the exact point where the problem lies.
But my guess is that you have an incorrect DNS mapping for the
PrimeNet server stuck in whatever name service you're depending on.
In which case patching the hosts file will fix the problem - however,
leaving you vulnerable to the same thing happening should the server
change its address again :(

There is a tracert.exe included with Win95 and Win98, at least.

Tried -- no change.

Windows [tracert] found 216.120.70.80 without problem.
Thanks to all for the efforts to date. Please continue, as I'm sure this
is something we can overcome.

Subject: Mersenne: Shutdown explained?
I am up and running again. It's not certain what I did to get back up,
but it might be related to the fact that a few weeks ago I added a
couple of internet cards. One was used to implement DSL service, the
other to network a second computer. When Prime95 finished an exponent
yesterday, it was unable to contact the server, and shut down. At
George's advice I then added UseHTTP=1 to my primenet.ini file, which
didn't help. A while later, this time with my second networked computer
turned on, I tried again, and this time Prime95 came up nicely. So did
Prime95 require my client computer, which has no Prime95 functions, to
be turned on? I don't understand. Can anyone explain this?

Currently, PrimeNet does not provide credit for P-1 factoring.
As I recall, George has said v21 will support it, but there will
have to be some modifications to the server to allow the crediting
to occur...
