And still, the last contact date is June 25th for this machine. After being out of the house for a week, the two machines has not contacted SETI according to the "Your computers" status. They are not able to report completed WU's and not able to get new WU's (since they already have too many of them that has not been reported). The two machines report "500 Internal server error" as the return status from the servers at berkeley. I give up! (unless some people at the project cam come up with something clever). I don't want to spend more time finding out what is wrong in the communication. All I know is that the linux machines with Fedora Core 12 will not run BOINC properly after some time. All other linux machiens (FC4 and FC10) are working find. Thanks to all who have replied to this thread. May the source be with you :) |

Latest news: Three more linux machines are not longer able to communicate with BOINC/SETI. Status: ALL linux servers are not able to crunch data! Windows machines seem to work OK. Does this mean that BOINC work on Windows ONLY???? I does not hope so! |

I asked earlier: http://setiathome.berkeley.edu/forum_thread.php?id=63664&nowrap=true#1124472 Do the SETI server see the same "External IP address" for all your Linux and Windows machines? If they connect from different External IP addresses they may be affected by the "HE connection problems". Did you try to set/use HTTP Proxy in BOINC options? http://setiathome.berkeley.edu/forum_thread.php?id=64691 http://setiathome.berkeley.edu/forum_thread.php?id=64691&nowrap=true#1129151 Â - ALF - "Find out what you don't do well ..... then don't do it!" :) Â |

Yes, all machines are hiding behind the same IP. I have not set up any proxy server. But I see that windows machines do get new WUs while all linux servers get http error (no WUs). There MUST be something wrong at the server side. |

There are some differences between Linux and Windows. Since 3 days, my Linux pc's are not able to download unless I add the 208.68.240.18 (download server) to the host file. My Windows 7 pc's use the same network, router and modem but do not have any problems downloading. I'm not saying that your problem is the same but the fact that Linux has problems and Windows does not, does not necessarily mean the problem is at the server side. Seti@Netherlands website |

I'd be very tempted to try one of the problem Linux hosts on a different ISP, and try one of the probem Linux hosts on the Network with all of the other hosts disconnected, Claggy |

If I read dahls's post correctly he is saying that all his PCs are connected through the same router to the same isp, but some (Windows 7) are getting/reporting WU, but others (Linux) are not. This suggests that it is a problem with the way his Linux PCs are set up. My first guess is that John is running a firewall on those PCs that is blocking a range of IP addresses, and needs an exception set for the S@H servers. By adding the ip208.68.240.18 address to the hosts list he is allowing communication, so, effectively solving the problem. This may of course have come about from an update to his Linux system, and possibly one he didn't know happened. For dahls's I can confirm that S@H runs smoothly on Linux under BOINC - just look at my computers for confirmation (I cannot comment on other projects under BOINC because my Linux crunchers are currently only doing S@H).

Reinstalled boinc today on one of the linux servers. It got a few WU's which was done within a few hours. But, when looking at the status for the machine, http://setiathome.berkeley.edu/results.php?hostid=5256434&offset=0&show_names=0&state=1&appid= it says that it has 96 WUs pending. Looking into the BOINC/projects/setiathome.berkeley.edu directory, there is hardly any files at all: [userx@r2-d2 ~]$ cd BOINC/projects/setiathome.berkeley.edu/ [userx@r2-d2 setiathome.berkeley.edu]$ ls -l total 7404 -rw-r--r--. 1 userx userx 0 2011-08-01 13:04 17ap11ad.23942.18472.5.10.150 -rw-r--r--. 1 userx userx 0 2011-08-01 08:36 17ap11ad.23942.18472.5.10.155 -rw-r--r--. 1 userx userx 0 2011-08-01 13:04 17ap11ad.23942.18472.5.10.156 -rw-r--r--. 1 userx userx 375332 2011-08-01 08:37 17ap11ad.23942.18472.5.10.161 -rw-r--r--. 1 userx userx 0 2011-08-01 08:36 17ap11ad.23942.18472.5.10.162 -rw-r--r--. 1 userx userx 0 2011-08-01 08:36 17ap11ad.23942.18472.5.10.167 -rw-r--r--. 1 userx userx 0 2011-08-01 08:37 17ap11ad.23942.18472.5.10.173 -rw-r--r--. 1 userx userx 375331 2011-08-01 08:36 17ap11ad.23942.18472.5.10.174 -rw-r--r--. 1 userx userx 0 2011-08-01 08:36 17ap11ad.23942.18472.5.10.191 -rw-r--r--. 1 userx userx 0 2011-08-01 08:37 17ap11ad.23942.18472.5.10.197 -rw-r--r--. 1 userx userx 0 2011-08-01 08:39 17ap11ad.23942.18472.5.10.203 -rw-r--r--. 1 userx userx 0 2011-08-01 08:39 17ap11ad.23942.18472.5.10.209 -rw-r--r--. 1 userx userx 52779 2011-08-01 08:31 arecibo_181.png -rw-r--r--. 1 userx userx 2536 2011-08-01 08:31 sah_40.png -rw-r--r--. 1 userx userx 25488 2011-08-01 08:31 sah_banner_290.png -rw-r--r--. 1 userx userx 35399 2011-08-01 08:32 sah_ss_290.png -rw-r--r--. 1 userx userx 9068 2011-08-01 08:30 seti_528.jpg -rw-r--r--. 1 userx userx 751 2011-08-01 08:33 setiathome-5.28_AUTHORS -rw-r--r--. 1 userx userx 17992 2011-08-01 08:30 setiathome-5.28_COPYING -rw-r--r--. 1 userx userx 1990 2011-08-01 08:30 setiathome-5.28_COPYRIGHT -rw-r--r--. 1 userx userx 2060 2011-08-01 08:30 setiathome-5.28_README -rwxr-xr-x. 1 userx userx 6641240 2011-08-01 08:35 setiathome-5.28.x86_64-pc-linux-gnu -rw-r--r--. 1 userx userx 71 2011-08-01 11:06 slideshow_setiathome_enhanced_00 -rw-r--r--. 1 userx userx 72 2011-08-01 11:06 slideshow_setiathome_enhanced_01 -rw-r--r--. 1 userx userx 75 2011-08-01 11:06 slideshow_setiathome_enhanced_02 -rw-r--r--. 1 userx userx 67 2011-08-01 11:06 stat_icon And the debug output file indicate that no files has been uploaded, only a few been downloaded.

Pending = work that has been sent to your cruncher and not reported 96 WU have been sent, but not reported yet, these may be "lost". There are 4 tasks that have been reported and are awaiting validation (all reported today), and awaiting your wingmen to do their processing. When you re-installed BOINC & S@H did you do a clean install or did you just re-install the applications? If you did a clean install the data (tasks to be run and results awaiting return) may have been removed, so "lost" - it might be worth looking in "lost and found" to see if they've been sent there, but it is a very long shot, as you would have to (manually) recreate the xml control files that tell BOINC what tasks are available, and what their status is. Under Linux I've found it worth letting the cache empty, and forcing a delivery before doing an update as it is just a bit less user tame than windows.

You didn't reinstall boinc. You installed a 64bit linux client on a machine where a 32bit linux client was installed. By doing this the 32bit client was deleted. And boinc deleted all tasks which had to be crunched with this client. And now all this tasks will reach there deadline. In the moment your are allowed to load only 16 tasks per day. It's not impossible to crunch seti with linux. Have a look at my machines. |

Dahls - I've just looked at another thread about unable to get downloads, do uploads or report finished tasks. It would appear there is "a problem" with the .13 address, so forcing which forcing the use of the .18 address overcomes. I think what is happening is that Linux is trying the lower (.13) ip address every time it attempts, not knowing about the higher (.18) address - hence your earlier comment about being able to work properly if you for the host address to the .18 address.

Thanks, Rob. I restarted BOINC and it immediately downloaded at least eight work units. But, then it started to fail downloads and now it thinks the project servers are all down. |

People are grabbing and returning work faster than it is being created at the moment. Because of all this activity, it gives the appearance that the servers are unavailable. When this happens, it is often referred to as a Distributed Denial of Service (DDoS). The only thing you can do is wait since your BOINC client will keep retrying on it's own. |

One reason for the very low production rate is the very high rate of rejection - if you look on the server status page you will see that the current "tapes" loaded have a fair number of "error" blocks, visually over half the tape of 14 blocks, which is far more than the usual 1 or two per tape. I wander if it takes more effort for the splitters when working with a high error tape over a low error tape?

One of my 3 hosts stopped being able to communicate on Thurs 25-Jul-2011 while at least one of the others is fine. I'm not using an http proxy and all hosts are behind the same firewall. Host 1: This one (2-CPU Fedora 14) http://stats.kwsn.net/host.php?proj=sah&hostid[]=5792705 hasn't had a successful WU download since Thurs 25-Jul-2011 13:08:48, For days, Boinc Mgr 6.10.58 showed a couple dozen WU's as "downloading". It finally burned through, uploaded, and reported all the WUs I had on hand, then I did a manual project reset. Since the reset, I haven't even been able to download seti_528.jpg for 6+ hours, much less any workunits. I've rebooted it. At the moment, it has complaints like this: 01-Aug-2011 15:25:35 [SETI@home] Temporarily failed download of setiathome-5.28.x86_64-pc-linux-gnu: HTTP error 01-Aug-2011 15:25:35 [SETI@home] Backing off 2 min 35 sec on download of setiathome-5.28.x86_64-pc-linux-gnu 01-Aug-2011 15:25:35 [SETI@home] Temporarily failed download of seti_528.jpg: HTTP error etc, etc Host 2: My other speedy box (Snow Leopard) has been uploading and reporting fine. (It normally crunches only during US EDT business hours, M-F, using a couple CPUs) Host 3: My slowest box (single-cpu RHEL5) has been grinding through an AP for 125+ hours, so I have no current info. If Host 1 doesn't get any work units by Thursday or so, I guess I'll reinstall, but I don't see why that would help. |
