F@H: testing connection?

[randomlinh]

Running in service mode, wondering if there is any way to test the network connection to ensure the client is communicating properly. I don't want to have to wait for a WU to finish to find out it can't communicate properly w/ the server.

Any way to do this?

Thanks
Linh

You could ping the F@H servers. You can find the server IP's here.. Work units are sent and recieved using port 8080. If the clients have already connected to fetch a work unit, there should be no problem sending them back, since they send back to the server from which they received it AFAIK.

well, i know that doesn't tend to be the case depending on the firewall it's behind. I have one machine set up that can fetch units fine, but cannot send them back. Which is why I was wondering if there was some kind of "test send" maybe.. heh.

Is it the console client? You could stop the client, restart it with the flags -verbosity 9 and -send all. (should work with the graphical client somehow, I have never used it tho...)The -send all flag will only work if there is a unit in queue waiting to be sent. You can look at the FAHlog.txt file and see whats up with the not sending bit. But, it will probably be a generic `could not send/connect` error message, not specific enought to deduce anything from.....
Is the machine that cant send behind a proxy? The send limit on the proxy too low? Needs to be 2meg or so, since a typical Gromacs results file is over 1meg! I didnt realize how damn large they are til recently.
Where are all the smart people when ya need em?!?!?😉
If nothing else, this is a bump for some help...

Oh yea, you can check here to see if the particular server you're trying to send to is down at the moment.

Good to know it uses port 8080... I just set up Kerio Winroute Firewall (partly - well, mainly - to keep that dasm MSN messenger from triggering my dialup connection every other freaking minute!), and am having quite a bit of fun (yeah right) figuring out exactly what holes I need to punch in my new setup to get everything that needs to work working.

With that said, do I need to open 8080 for incoming connections, or will outbound connections be enough? Any other ports I need to enable? As you can probably tell, I'm a rather tcpical network-challenged individual, so any help would be appreciated. 😉

If you do not use MSN Messenger, you can remove or disable it. Check
here for instructions on doing this. This guy is an Uber-guru and has a slew of great tips and tricks.
As for Kerio, sorry I aint familiar with it but here goes. F@H actually uses both port 80 and 8080, but port 80(http) is almost always open or allowed thru any firewall already. Port 8080(http-alt) sometimes isnt, so a rule may need to be made for it. I would allow 8080 out since that seems the main direction F@H uses it.

is there any working 3rd party program that can tell me the current status of of a WU for the client version?

Give a look here for a lot of good info about 3rd party apps for F@H. I use FAHLogStats, I like its summary feature that tells me the status of my crunchers over the home network.

Well, the firewall has brought it into check, but being able to save 8MB of RAM would be nice anyway (for some reason msmsgs.exe runs in the background without a systray icon, and it keeps restarting whenever I kill it). Thanks for the tip. 🙂

I just delete the .exe for Windows messenger, hasn't bugged me since.
