Over the past few days we've been trying to get our download server (penguin) onto a new network. All kinds of confusing issues as this involves two new routers under our control (one here at the lab, one down at the PAIX), and several third parties along the way. The map of the route, currently on the dry erase board by my desk, is a bit, well, complicated. The question "why are we doing this" will be answered once we are successful. Currently, while one of our web servers is on this network, we can't do much else. The download server is hitting a bottleneck somewhere along the way that has yet to be discovered.

Meanwhile, kryten is still being a whiny baby. Last night I cranked up the number of apache listener processes to help quicken the pace of outage recovery, but I never had to resort to this before. Another mystery.

As I write this, things are a bit off, and we know this, but we are trying to collect some more diagnostic data about the new network before "falling back" for the rest of the weekend. More surgery come monday.

Is this why despite all up and running I cannot upload anything for the past couple of days (happening on both computers). I miss you tech page which usually would inform us noncomputer people about why we are having problems. Thanks for any info/help you can give me. Been doing this for almost 8 years now.

I'm guessing this to be the case here and as I have multiple projects running, shutting off all network activity is overkill. I simply suspended SETI on my workstations for now.

I haven't been able to up or download since Tuesday on 2 of my computers, while a third seems to have no trouble. Any ideas?

Hi guys,

Try restarting the BOINC service. Berkeley is making changes to its network, causing some IP addresses to change. A restart should do the trick, but if it doesn't, flush your DNS cache and restart the BOINC service. To do so, if you're using a windows box, open a command prompt and type ipconfig /flushdns.

Regards,
Wander

Restarting BOINC did enable the one computer to down and upload, but I have had to restart it a few times in the last few days to get it to work. A little odd, since it is only the one, but workable.

Flushing the DNS and restarting boinc did not cure my inability to upload completed work.

Although I am really enjoying seeing all the tech posts by the SETI team in the new section of the message boards.

I tried it twice on my MBP with no success either. Then I rebooted, and everything worked fine.

Sometimes a DNS cache is held by routers/high speed modems, etc. Rebooting usually tells the router to check DNS again as the OS reinitializes itself with the router upon coming up.

With as many brands of hardware, firmwares, etc. that are out there, not everyone uses the same logic.
