Message 21298 - Posted: 8 Mar 2009, 22:28:59 UTC

For the last month, I\'ve been unable to connect to this project, reach this website, or even ping lhcathome.cern.ch (138.37.50.115). After realizing that I could ping it from work or school, but not home, I spent the last few days troubleshooting.

I determined that the problem was not on my end. Then I thought to try changing my router\'s external IP address since my AT&T DSL uses PPPoE to assign dynamic IP addresses. That fixed it.

Does lhcathome.cern.ch blacklist any IP addresses in the 70.254.192.0/22 range? If so, could somebody please remove those blacklist entries seeing as it\'s a dynamic pool of IP addresses? It\'s not cool that innocent people like me get banned due to other people\'s server abuse.

You\'re not the only one. Maybe you have read this thread over at E@H already.

BAH.........this goofy site does seem to like my old machines more than my dual processor machine because I see them getting work and this one didnt get anything again.

MAGIC, since you appear to have posted to this thread from your dual processor machine, your IP address isn\\\'t being blocked. When I had an IP address that was blocked by the server, I could not even go to the http://lhcathome.cern.ch/lhcathome/ homepage.

Oh I know it isn\'t my IP being blocked since 3 out of 4 of mine are on the same DSL

But it just doesnt like sending me any to this machine unless there is lots of work and I see that and load it here myself.

With the short bursts of work here, there\'s no way to guarantee that everyone will get some. Your hosts\' work queue scheduler requests might be such that they aren\'t asking for new work from LHC when it is available.

Posters are getting sidetracked here. This thread is not about the lack of work, but rather the inability to contact the server all together from certain IP addresses. I feel like every time I have serious trouble with this project, nobody cares.

Honestly, I\'m a little frustrated that no moderators or admins have acknowledged my (our) problem. Combined with other problems (like 4-year-old tasks preventing me from deleting dozens of old hosts), I am tempted to leave this project.

Can you post the messages you get in the messages tab of BOINC Manager regarding this problem.

Looking at your computer pages shows that all the hosts listed (nice list btw) have contacted the schedular recently. The fact that there is no work available means that you got no work.

But if we could see what errors you are seeing it might help us diagnose the problem.

If you\'d read my original post, you\'d find that I\'ve already diagnosed the problem. I found a workaround by changing my IP address. Since it is no longer an issue, I don\'t have any messages in BOINC Manager to give you. The problem was not only preventing my hosts from contacting the server, but was also preventing me from going to this website. If I was still having the problem, I would not even be able to post this message from this computer.

I started this thread to bring attention to the issue, in case other people are having the same problem. Indeed they are, as ziegenmelker, Donald A. Tevault, and Gary Charpentier have all pointed out.

Unfortunately, the thread has been hijacked by people talking about the lack of work (of which we are all aware). This misses my point entirely.

OK.

If you are in contact with the others who are having problems are you able to ask them for a copy of the messages they are seeing in BOINC Manager and post them here?

The problem has nothing to do with BOINC at all. And I\'m not in contact with anybody. Clearly you haven\'t read this thread.

Hi, long time since I visited the LHC fora.

My last, attempt to get some work, looks not so good:

6-10-2009 16:50:57 lhcathome update requested by user
6-10-2009 16:51:01 lhcathome Sending scheduler request: Requested by user.
6-10-2009 16:51:01 lhcathome Requesting new tasks
6-10-2009 16:51:06 lhcathome Scheduler request completed: got 0 new tasks.


NO contact problem, here in Holland.

Nope, simply no work to do.

Take a look at the \"apologies\" thread in the Café for more info.
