Mersenne: GIMPS on new iMac ??
How do you think GIMPS will run on the new iMac? (Or will it run at all?) Cheers... Russ _ Unsubscribe list info -- http://www.ndatech.com/mersenne/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
Re: Mersenne: Prime freezing when connecting by DSL to Primenet
Interesting... I have had that happen to me as well a few times with PCs on a DSL (but without AOL). It doesn't happen on a regular basis but does lock up the program (v21.3) for hours or days at a time. Just caught one today that had been stuck like that for seven hours, even 'end task' couldn't stop it. I had to reboot the PC, then it connected and reported in just fine immediately afterwards. Irv, I know this is no help, except to let you know you aren't the only one...

I've been using Prime95 with DSL for about 16 months, and AFAIK, it has never happened to me. ++ | Jud McCranie | || | former temporary part-time adjunct | | instructor of a minor university | ++ _ Unsubscribe list info -- http://www.ndatech.com/mersenne/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
Re: Mersenne: Prime freezing when connecting by DSL to Primenet
I am running version 21.4 of Prime. I recently started using a DSL connection on AOL. ( I am using Version 7.0 of AOL). Since I started using this arrangement, Prime locks up whenever it connects with Primenet. After some delay, during which time everything stops, Primenet reports an ERROR 12031. The only way that I can successfully report to Primenet, is to connect to AOL using my modem. I've been on DSL for several years now, and autoconnect ISDN-via-ethernet for 3-4 years before that, and have several clients running on machines that are on much higher speed connections, and have most of them set to check in every 2 days (that way I can easily find out if a client has stalled), and *NONE* of my 10 or so clients have ever had any problems connecting to primenet. Now, I don't use AOL at all. My ISP is a regional who uses static IP bridging, I'm connected to the DSL modem by ethernet, and don't run any special software, just TCP/IP. _ Unsubscribe list info -- http://www.ndatech.com/mersenne/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
Re: Mersenne: Prime freezing when connecting by DSL to Primenet
I wonder whether this is caused by Firewalling software or automatic virus detection software. Has this avenue been investigated? Some of this software might have the power to block network connections or basically suspend the program trying to make them until such time as Wild guesses: 1. Is the server actually closing its connection to the client (and vice versa)? I seem to remember seeing an active connection listed in netstat even thought the communication had finished and I'd dropped the dial-up connection. If the firewall software was trying to do some sort of content verification or other checking, might it be waiting for the connection to close? 2. Is something trying to do a reverse DNS lookup on the server before it allows it and failing? Does the server have a reverse DNS entry? (I've just checked and it doesn't.) 3. The fact that the HTTP request asks for an .exe (/cgi-bin/pnHttp.exe) might cause some sort of virus checker to kick in and insist on interfering with the reply. 4. Is the server somehow being blocked? If there's some sort of URL/content checker interposed in the connection, is it classing the server as an unknown group (we assume we're not in the sex and violence category :-) and trying to filter it or something? It seems to me that if the connection never closes, and there's virus/content checking in place, then there might be an explanation for a very long wait. Perhaps I've been able to offer some clues.
