Arrow My next factoring job.

Actually I would not mind starting another factorisation , but I guess I need to clear this one first.

I have turned debug on, and Xed the password out of the result...

I had a chuckle when you said "The 23.8 sources are not available for download". I guess the source is now closed for some good reason... LIN for LEA maybe?
(http://primes.utm.edu/glossary/page.php?sort=Illegal ... We would not want to generate an illegal prime by mistake would we :-)

Re: improvements to the mprime source. I would love to make the software a rpm package, with an automatic cron job to restart mprime after system shutdowns. (maybe even a GUI/form for the text input challenged. )

ECONNRESET - how utterly uninformative. Maybe someone who knows sockets programming far better than I can come up with an explanation for why ping and telnet works, but my simple connect, send, recv does not.

You can email the results to me at woltman@alum.mit.edu You can get a new exponent from http://mersenne.org/range2.htm

The only reason 23.8 sources aren't available is I've been too lazy to put them together and upload them. The sources that are there are nearly identical to the 23.8 sources - just a few bug fixes since then.

Thumbs up Good news???

I manually entered the URL (produced by debug) into Galeon (A modern/nice web browser):
http://mersenne.org/cgi-bin/pnHttp.e...DD1ADB296E68AA

And got as a reply:
pnResult=0

It seems like a very small result for such alot of CPU cycles. I hope there is some kind of parity/CRC check in it.

Then I checked my primenet_report:
http://www.mersenne.org/cgi-bin/primenet_report.pl

And got:
------- Exponents Cleared since last Synchronization -------

romeo with 18080627 nolonger appears. So... I think I am done.

It seems that the URL generated by mprime can be entered directly into any other web browser to affect the mprime server update. I this is so, then this means the problem is in the mprime client software. Maybe something as simple as a carriage return being sent when a linefeed is expected??? When I do my next job I will try the static linked version of mprime. This eliminates other permutations as we can be sure that some local library call isn't messing around with the URL stream.

In case other linux clients encounter a similar problem with connecting to mprime server:
I am using Mprime 2.35 on Redhat9 kernel 2.4.20-28.9.
And rpm glibc-2.3.2-27.9.7 for /lib/ld-linux.so.2 libm.so.6 libc.so.6 (as demanded by mprime client)

Im done. Time for my next job...

Thanx

Thumbs up

Further (good) news....
the problem mysteriously "went away" on the 12th of May.

So I am extra happy...

i.e. problem WAS:

Error in recv call: 104
ERROR: Primenet error 2252

"I didn't change anything".... Here are the RPMs I installed around that date (May) for reference incase someone else has a similar problem...

/var/log/messages.1:May 12 21:35:34 romeo syslogd 1.4.1: restart.
/var/log/messages.1:May 13 07:27:57 romeo syslogd 1.4.1: restart.

The only thing that vaugely looks like a network/html RPM was lynx (or ethereal).... This was previously not installed, and I am reasonably sure it is not required for mprime.
