WU's Not Being Assigned by 171.67.108.102/171.67.108.105/?

[foldy]

I tried to download a new work unit and 171.67.108.45 this time redirected to 171.64.65.84 and I got a work unit.

I don't think it is possible to exclude assignment servers using firewall rules. The client will still try the IPs and then fail the same way.

[SteveWillis]

Blocking the ip immediately worked for me on my Linux box and has continued to work. I tried everything else unsuccessfully.

It looks like the server 171.67.108.105 needs a reboot/restart -- or hopefully nothing more drastic -- to get it running again. Anyone awake in CA yet to get a handle on this problem? I was on-track to achieve slightly over 1 billion points this month, but if this doesn't get fixed it ain't happening.

[foldy]

If this is really working then on Windows the cmd looks like this:

netsh advfirewall firewall add rule name="FahClient workaround" dir=in interface=any action=block remoteip=171.67.108.105

To remove again:

netsh advfirewall firewall delete rule name="FahClient workaround"

Put them in a admin cmd shell and press enter key. It should say OK.

Hi,

FAHClient connects to 171.67.108.45 that keeps on assigning the same work server 171.67.108.105 which doesn't assign any work unit.

Shouldn't 171.67.108.45 detect that same client or IP is asking again for WS and assign another work server instead of dumbly assigning the same one again and again and again??

An even better option would be to implement in the next FAHClient version the fact that when the WS did not assign a WU, FAHClient gives this information, alongside with the IP of the faulty WS, on its next WU request so that a different WS should be assigned. And several requests like this should raise an alarm about the faulty WS.

We recommended that about 6 months ago along with other things and still no 7.4.17.

I'm back to not getting WUs. My requests switch work servers but I'm still coming up short.
I wonder if they don't have enough in the queue

[Aurum]

Is there someone that can shut down 171.67.108.45 or reset it

Code: Select all

14:52:41:WU02:FS00:Connecting to 171.67.108.45:8080
14:52:42:WU02:FS00:Assigned to work server 155.247.166.220

When F@H switches work servers I get a WU. Until it switches I get rejected:

Code: Select all

14:52:57:WU02:FS01:Connecting to 171.67.108.45:80
14:52:57:WU02:FS01:Assigned to work server 140.163.4.245

I have merged the five separate topics on the same problem and am in the middle of writing a message to report this to PG.

Thanks to Steve Willis, both of my GPUs are running again. His method for Linux worked fine.

[Leonardo]

I had two machines, both Windows 10, with the downloading problem. Here's what worked for me: On one machine, in the console manually alternated the setting from Fold to Pause; the other machine I rebooted and it picked up a work unit right away.

Thanks for the upvote

I didn't mention that your firewall has to be enabled.

Code: Select all

sudo ufw enable

I just noticed that when work server 140.163.4.241 with 61,356 WUs in its queue it does not assign me one it switches me to WS 140.163.4.241 with NO WUs in its queue and hangs:

Foldy I tried your approach and blocked 171.67.108.105 and 140.163.4.241 in my CMD windows as Administrator and it said "ok" and I rebooted. Maybe it works:

This time it switched me to another WS so maybe the cmd did work by getting it to switch. Other rigs still hang on 171.67.108.105 or 140.163.4.241. Do i need to reboot to have this cmd take affect

Foldy I tried your approach and blocked 171.67.108.105 and 140.163.4.241 in my CMD windows as Administrator and it said "ok" and I rebooted. Do i need to reboot to have this cmd take affect

No reboot necessary firewall settings are live.

Don't forget to remove the setting when servers fully work again.
