Jason, I've tried your script

Der er ikke registreret en grænseflade med dette navn på routeren.

The danish message translates as "There are no registered an interface with this name on the router", no idea what that means, but netcard isn't disabled.

Did you put the interface name from your Network Connections list ? Usually 'Local Area Network'.

Did it 10 secs ago, and it works now :) In danish it was "LAN-forbindelse".

Correct, you would have to substitute your network connection name for the "Wireless Network Connection" in the file. Also, the delay in the calibrated delay section would likely have to be adjusted. Those are the two things I know of so far, but no way to check if it actually works here or not yet ;)

Uhhh, how did you get the server to resend?

Set NNT, do a report (with at least one Wu to report), wait a few seconds, then before Boinc gets the reply, disconnect from Wireless/Disable Wireless Card/Disconnect from Net/maybe even setting Boinc to Network Activity Suspended might work,
use another computer to see if host has reported on host page, wait until Boinc has timed it's connection out, (if you have set Network Activity to suspend, you'll have have wait at least 5 minutes)
then depending if Boinc has managed to report, unset NNT, and ask for work, if you're managed to report that Wu twice, the Server will resend Ghost work instead of fresh work,
if the host page didn't update, wait for Boinc's connection to time out, then try again, waiting a few more seconds this time, the number of seconds you have to wait depends on your connection, how many tasks you're reporting, and how sluggish the Database is at that moment, try 5 seconds first, then work up from that,

Claggy

Hm, is there another way? Maybe by editing one of the files in /var/lib/boinc-client ?

Finally !!!

HostID = 4188485

    867 WU 'In Progress'
    867 WU on board

      0 Ghost Work Units (%)

Who the hell is General Failure and why is he reading my harddisk?¿

Hm, I reported a WU twice (like suggested), but I don't get any ghost units resent.

---

Oh sorry, my client doesn't ask for new work ... and I can't do that manually.

No, before the resend works, Boinc scheduler needs to ask for work. If your cache is full it wont ask for work and the resend trick wont work.

I just got 11 resends. I changed the calibrated delay to -n 7, but when the servers is busy like now it's just about impossible to know what the right number is.

Hm, I reported a WU twice (like suggested), but I don't get any ghost units resent.

Btw do you know if you have ghosts at all? It seems the slower PCs don't get that many ghost if any at all.

Even in XP the netsh command should work

netsh interface show interface

Admin State State Type Interface Name
-------------------------------------------------------------------------
Enabled Unreachable Dedicated Local Area Connection
Enabled Unreachable Dedicated Local Area Connection 2
Enabled Unreachable Dedicated Wireless Network Connection
Enabled Unreachable Internal Internal
Enabled Unreachable Loopback Loopback

Note when you pick the active connection you need the "" around the connection ie.
"Local Area Connection"

So this line
netsh interface set interface name="Wireless Network Connection" admin=ENABLED
becomes this line
netsh interface set interface name="Local Area Connection" admin=ENABLED

I get the following when the following command is executed.

netsh interface set interface name="Local Area Connection 2" admin=DISABLED
or
netsh interface set interface name="Local Area Connection 2" admin=ENABLED

One or more essential parameters not specified
The syntax supplied for this command is not valid.  Check help for the correct syntax.

Usage set interface [name = ]fName
            [ [admin = ] ENABLED:DISABLED
              [connect = ] CONNECTED:DISCONNECTED
              [newname = ] NewName ]

      Sets inteface parameters.
     
      IfName  - the name of the interface
      admin   - whether the interface should be enabled (non-LAN only).
      connect - whether to connect the interface (non-LAN only).
      newname - new name for the interface (LAN only).

      Notes"
      - At least one option other than the name must be specified.
      - If connect = CONNECTED is specified, then the interface
        is automatically enabled even if the admin = DISABLED
        option is specified.

Boinc....Boinc....Boinc....Boinc....

I don't believe this script would work.

If I remember there needed to be a communication to the servers that both reported some work and requested new work. That request then needs to time out due to missing the acknowledgement. 5 minutes I believe. Then Boinc would make the same communication again and the servers pick up the double reporting of the same work which indicates that the ack was missed by the client. This would then trigger the sending of 20 ghost work units.

Boinc....Boinc....Boinc....Boinc....

Apparently it doesnt work on XP. http://support.microsoft.com/kb/262265

The work around is to change the IP address to a non working one for your router and then back to dhcp (or a working static address).

Disable
=======

netsh interface ip set address <interface name> static <ip address> <mask> <default gateway> <gateway interface metric>

e.g.
netsh interface ip set address "Local Area Connection" static 1.1.1.1 255.0.0.0 1.0.0.1 1

Enable
======

netsh interface ip set address "Local Area Connection" dhcp

Tried on XP and works OK.

...I don't believe this script would work.

Quite possible. I am unable to test & refine the logic & delays involved at this time, so leaving it up to those who use the manual method successfully to attempt adjustments (if they want to). There are plenty of ways to acheive a five minute delay if needed ( adding a pause to 'press any key to continue' line would be one way that enables the mentioned manual check via another machine of the host update.)

The curious thing that I see with a non-script induced resend, is in the timing & sequence involved. I beleive this is the procedure we're trying to trigger (?):

...

I don't see a five minute interval there between presumed broken ACK & request.resend response, but certainly longer than a few seconds. That 22 second preriod between request and realising the ACK wasn't received looks like the key interval to play with to me, which shoud correspond to the section marke 'calibrated delay' just before disabling the network adaptor... hopefully.

That "Couldn't connect" didn't actually send the request, having failed to get a SACK after three tries. The request which initially reported at least some of that work must have been earlier, and would indicate either timeout or http error.

Btw do you know if you have ghosts at all?

I had many of them, so I completed my work and detached/retached.
Now I don't have any.

All the ghost I have are now form one date. September 11 three time codes 11 sep 2010 2:53:41UTC 50 work units 11 Sep 2010 2:40:42 63 units and 11Sep 2010 2:36:20 39 units. Since I live in the Pacific time zone -7 hours ?? it makes it Saturday night our time. look at some of the work units that timed out and some that 4 time out replies 2 from one day and 2 from the next set of work units. The 152 work units will time out in the next 10 or 12 days ?? and hopefully things will get back to normal. It's all those ghost that are causing high pending credit numbers.

I modified the windows batch file to use choice.exe for the step delays.

I modified the windows batch file to use choice.exe for the step delays.

Most SETIzens will not have choice.exe installed, its not longer part of windows.

However, it can be downloaded from http://winsupport.org/utilities/freedos-choice.html
