Assigment Server Connection Problems

Can someone please take a look at these logs and tell me what I am doing wrong?

I am trying to update my client on my box at work. I have permission to run the sw but have been told don’t bother the IT support folks with questions or ask for changes (ie firewall changes).

I have been running the ancient Gromacs core v1.90 from March of 2006 since it came out. I tried to update the core sometime last year to something newer but always ran into connection issues. At the time, I said just go back to what works and have been running v1.90 since. My box was recently replaced and I now have a Quad core Xeon and a Quadro FX1700 that I would like to make the best use of. While v1.90 of the CPU core continues to connect and run just fine, I cannot get the 6.23 GPU client to connect and get a WU. I have tinkered with the XP SP3 firewall settings and added each cores .exe but no luck. I have tried to connect to the page that tests your machines connection to the assignment server (page address escapes me at the moment) and it returns OK on port 80 but not on 8080 as I believe that is blocked by our firewall. Doing searches through this forum and the F@H forums, I have tinkered with the config settings to no avail.


When I run the v1.90 client, it looks like this. (showing end of last unit, server connections, start of new unit)

When I try the a newer CPU client or the 6.23 GPU client it looks like this. The Machine ID it set to 5 because I have 4 instances of the v1.90 core running, one on each of the CPU cores.

Any suggestions would be greatly appreciated. I am not sure what changed between the v1.90 clients connectivity and the newer CPU and GPU clients but I cannot seem to get the newer stuff to connect and grab a WU.
 
Try to remove -advmethods and check if it connect fine. Some flags might force the client to pick certain server and some won't respond to requests.
 
I actually added the -advmethods after reading a forum post that said it opened up a larger pool of possible WUs and may help getting a WU assigned. I just tried it without the -advmethods and nothing changed.

First part:- You don't want to use IE to connect through with the v1.90 client.
Its a legacy setting from the days of dailup.

Second part:- Both those links should come back with ok.
If they don't, then try turning your firewall off and retry them, then trun the firewall back on.
That will show if the firewall is blocking the connection or not.

Luck ............ :D
 
Thanks for the tip on the v1.90 client. I have kept the same settings for years, just copying the folder over to new PCs as I got them. I will get it changed eventually but at least it is working at the moment.

As I said in the original post, Port 8080 is blocked by the main corp firewall. The link on port 80 returns OK but the link on port 8080 returns 'connection was reset'. I have no control over that firewall and have been told not to ask the IT support folks for any help/changes. I also cannot turn off the Windows XP SP3 firewall due to a group policy. I can add exceptions which I have for 80 and 8080 but cannot turn it completely off.

Is port 8080 access absolutely necessary to connect to the assignment server or can it work over port 80 only?
 
You can check which client/server uses which port Here.
I think looking at that table, the GPU client needs port 8080 open to get work.

Luck .......... :D
