Another wacky weekend. Sounds like we were sending out a bunch of short workunits, which strains our bandwidth resources. Plus uploads were clogged for a while. The server was too busy and dropping connections, so the uploads weren't even reaching the server. On Saturday morning I did some TCP tweaking and seemed to clear up that log jam for the time being. This morning it came to my attention that we've been sending out workunits with the "application/x-troff-man" mime type. This was because files with numerical suffices (like workunits) are assumed to be man pages. This may have been causing some blockages at firewalls. I changed the mime type to "text /plain." The SERENDIP web page was updated for the first time in many years. There's a link on the front page about that. We plan to get the public NTPCkr candidate lists on line this week, ready or not. Trying to squeeze a couple more features in at the last minute, but I'm sure there will be bugs to work out and more features to add later on. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

Really looking forward to the NitPicker. If there are bugs, we will try not to Nit-Pick too much. We'll go easy on you..LOL Its very exciting, thank you for the work you put into this! SERENDIP website is cool! John. |

Sounds great and thanks for the work you put in. I did get a bunch of small work units. the small ones are 5-15 minutes. normal mb's are 45m-2 hours. I crunch them all anyways. |

Hope this is the right place to post Our Zyxel router is blocking some connections from 208.68.240.18, residing on your network, for the following reason: 3 2009-07-05 16:27:43 warn IDP from Any to DMZ, [type=Sig(8002891)] WEB-CLIENT multipacket CHM file transfer attempt Action: Drop Packet Severity: medium 208.68.240.18:80 80.96.218.202:4137 ACCESS BLOCK This is a recurring action, (almost 40 in 1 week) The page with description from Zyxel: https://mysecurity.zyxel.com/mysecurity/jsp/policy/policy_detail.jsp?TYPEID=8002891 |

Deepcuts: That router is apparently using Snort as that's one of their rules. In general, that's a good thing. My guess is that BOINC is trying to download something (either an update or more likely just a specific workunit/task) that is inadvertently tripping this particular snort rule. It's what's called a false positive. Check your transfers and messages tabs in the BOINC manager (you'll need to click the Advanced View link at the bottom of the little BOINC applet first if you haven't already). If I'm right, you'll probably see where it's been trying to download a file over and over again and it keeps failing. If it's just a workunit, you should see it listed with a status of downloading under the tasks tab. Just select that task and click the abort button. That should fix your problem. I've scouted around a bit and so far I haven't seen any mention of this sort of thing elsewhere, so I doubt it's a fundamental problem. Chances are you were just unlucky enough to be assigned a workunit snort doesn't like. Please let me know how it works out. If it's not just a particular workunit, or it happens again, someone should probably dig a bit deeper and see if there's a way to work with the Snort guys to solve the problem permanently. I'm not an expert on Snort or anything, but I'd be happy to help if nobody better qualified steps up. Good luck! |

Indeed, work units are not downloaded anymore. It might be a false positive, but then again it might not. I posted this problem so the people who program BOINC can take action (with BOINC or Zyxel). Have a nice weekend |

I changed the mime type to "text/plain." But is it human-readable text? I don't think so... Contribute to the Wiki! |
