155.247.166.219 & 155.247.166.220 are now hosed [Not Now]

[Joe_H]

An additional thing to keep in mind is that your WU is among thousands returned each hour. The first of those servers is currently handling about 3000 returns an hour, the second about half that many. AT the same time that means they are also sending out about the same number of WU's.

Is it possible to "blacklist" these servers somehow because they just don't seem to work for me... I tried disabling all my firewalls (hw & sw) but still no connection (not even with browser, neither :80 or :8080) other than PING which works fine. So I think this leaves pretty much either my ISP or server (geo?)block to blame?

CPU uses other servers and works fine all the time but for the GPU, once again, over the weekend my log looks like this

What does your browser say when you open http://155.247.166.219:8080/ or http://155.247.166.220:8080/

Blacklisting those servers (even if it's possible) would gain nothing. The Assignment Server is designed to direct your cli

Which version of FAHClient are you running?

[e3072743]

What does your browser say when you open http://155.247.166.219:8080/ or http://155.247.166.220:8080/

In Chrome I get "ERR_CONNECTION_TIMED_OUT", same with :80. I'm using client v7.4.4.

[bruce]

There are several factors in ivolved that can cause your FAHClient to fail to connect to those two (actually 4) URLs. Some problems can be resolved on your end and others require actions at the server.

First, let's talk about ports. At the server level, FAH actually uses port 8080. The servers are supposed to be configured to redirect port 80 to port 8080, but that doesn't always happen (especially on those two servers) and somebody has to re-enable that port redirection. On your end, if you connect through a proxy server, port 8080 may not work and only port 80 will work for you. Can you connect to port 8080 on ANY of FAH's servers? If that's a problem, you're probably using your employer's internet connection and how they handle their security is up to them.

Right now, I'm getting through to either server on port 8080 and both are timing out on port 80. I've notified the appropriate folks, so the first issue will probably be resolved shortly at the servers.

Next (3rd & 4th), it's possible that the security software on your computer is blocking all access to those servers or the servers, themselves, can be off-line. You can test that possibity by temporarily disabling your security software.

5th, the server may not have any more WUs that fit your configuration. The primary job of the Assignment Server is to find an active work server that DOES have WUs that fit your configuration. Ordinarily there are several valid choices it can make.

6th, if you have an unusual configuration (say your client is seeking an assignment for 7 CPUs, a combination which is not valid) there may not be any work for you.

As you can see, it's rather complicatged. When we're asked to fix "the problem" we have to gather enough information to figure out which issue is causing the problem. I can test 1, 2, and 4 from here. With a few questions, I can often get you to resolve 3 and maybe 6 on your end. Each possibility is generally quite rare.

[e3072743]

Thanks Bruce! I did some testing with the server list on http://fah-web.stanford.edu/pybeta/serverstat.html and it seems I'm unable to connect to ANY server with my browser using the port 8080. Port 80 does work with ALL available servers, except these two. Disabling my software firewall doesn't change anything so it must be some issue with my router/ISP blocking 8080. I don't have any proxies configured anywhere but maybe finding a good free one and setting it just for the FAHClient would be useful to try and avoid this issue. Hopefully fixing the port 80 on the server side will also help.

Is anyone else having slow upload to these servers again? I'm on a 80Mbit down/20Mbit up VDSL2+ in the UK and usually don't have any issues with F@h speeds, but it's just taken me nearly 15 minutes to upload a 1.77Megabyte WU return which I thought was being a bit too slow. I'd expect it to go up in under 5 minutes max, and that's with heavy contention due to time of day etc!

So I surmised that my connection and settings this side are working fine...

A little over 24 hours later and someone must have kicked it in to touch a little, as this is more in line with what I would usually be expecting! Similar filesize upload to the same server just now from the same desktop on the same connection.

Looking a lot better now, so currently back to normal I guess. The fact that other people are suggesting that there's something wrong with it though may warrant people at least keeping an eye out for a while at least. Anyone know if anything was done and if so, what was the problem just out of interest?

When FAH sets up a server, they're at the mercy of the network services firewall's rules. Some ports required by FAH's servers have been blocked.
I have been assuming that server port 80 was blocked by something that could be fixed on the servers, themselves, but it turns out it's the campus firewall.

I still can't get through on http://155.247.166.219:80/ or http://155.247.166.220:80/ Fortunately that it only affects a limited number of clients.
Other ports used by FAH servers have also been having troubles.

There have been ongoing discussions for several weeks.
