Re: Network problem

Nope none of that Viktor – two independent machines – even checked the XP license today as someone at microsoft indicated, that I may have the same serial number running on the two machines. Even checked for conflicts in IPs etc….. everything is fine. Mycrofth’s theory seems most compelling so far ….. the Agent is self distrusting when it recognizes a second instance of itself running on the LAN – even though they should run independently.

I have switched the agent off on the second machine as I cannot assign any more time to the task. I figured that there is absolutely no sense in running two agents at different times as it boils down to having one agent running all the time – the PC#1 is a Pentium 4 and it cooks roasts those hamburgers a lot quicker than the PC#2 – and AMD 1800MHz engine.

….Once I have some time I will get someone in to have a look at the network, run the tests, document them and then post them for some help. Maybe a peer to peer network doesn’t like two agents running on it at the same time….. I don’t know.

Thanks for spending time trying to figure this bummer out…… no better name for it sorry Admins!

Re: Network problem

I thought of one more thing that might do this. Perhaps you have a power supply problem of some sort. Are both plugged into the same UPS or something? Maybe the line voltage is on the harry edge of just barely letting the second PC run or something and as soon as there is just the right kind of activity on the other PC which might change the voltage, the power supply might produce a glitch causing things to crash. Just another wild idea.

Viktors - Re: Network problem

Viktors - I understand what you are saying. I donot use a UPS. Both PCs are connected to the mains directly. If this was a power issue it would affect windows and other applications and not just the agent itself. . . I push power realted issues down the list - worth checking for peace of mind, but nothing else at the moment. The other thng is that agent resets itself internally. It continues running, but just starts another task - downloads new data and starts crunching the data. The application (Agent) does not reload. This implies that the agent:

1. is under the impression that it has completed the data upload and requests for new data - some sort of status on task status changes or is changed by another application

2. looses track of its local status (all the data) and thinks that it is loading for the firsttime and therefore dwonloads new data (files deleted, corrupted or something else)

3. has an internal bug that makes it unstable when running in my environment ... AMD, graphics card, memory, netwoek ... don't know

4. none of the above sad

What is realy amazing me, is that I am the only one of 100'000 PCs running the Agent reporting this issue. . . unless other people have just given up sad

Have a good one!

We sometimes wonder if there are problems that people have that they solve by getting rid of the WCG program without telling us why. confused But your problem is the only report of something like this one. Which is why I concentrate (perhaps incorrectly) on your network setup, which is an unusual design.

Re: Network problem

RobStab
I have a similar configuration to yours. I use an XP machine as my Internet Connection Sharing Server. DSL=>XP =>out another Ethernet card to a router that other machines connect to. I forced a nonstandard IP number set in the ICS(#1) to connect to the router and a nonstandard group of IP numbers for the router to dispense using DHCP. Then all other machines obtain their IP numbers dynamically from the router..and they are all non-standard (the group that are normally used for internal networks).

I run the network setup wizard on all new machines and make sure that they obtain the IP addresses automatically from the router. Oddly enough they do not seem to find the DNS automatically and I have forced those to a known good set of DNS servers.

Everything works like a charm.

Now I go back to what I think Viktors said about the awareness of one WCG instance of the other. That sounds like the root of the problem to me.

Perhaps I do not understand your network settings. I like others here am no network expert and usually have marathon battles with network software till I finally get it working.... So what I am saying could be wrong or superfluous. That having been said, I would try to make sure that your #1 machine knows it is the ICS host and that it understands that the second card is for the internal network. (Actually machine one thinks the router is a PC - rather than a router). That way he always communicates with that "PC" using a set IP number. The fact that there are actually several PCs on the other side of the router is of no consequence to him...he merely passes data through as if it were all from one PC (actually the router). In this way, all the traffic coming from all the other PCs pass thorough the #1 PC with him really knowing what is in there... On the inbound side (PC1 inbound from Internet) once incoming data get past the firewall, he just passes the data to the IP# for the router and the NAT function in the router send it to the correct PC (to whom he has assigned the IP numbers to). I think I just broke about a hundred grammar rules and gave myself a headache.

So... Mine works using ICS on my "#1" machine. Wired like yours. The rest of the machines are ICS users and obtain their IP addrs from the router.

If you have a network software configuration different than this, which I presume you do, I would bet the problem is in that configuration...which allows processes on the #1 machine to be aware of processes on another. In my configuration, this is not possible.

If I have confused you, I appologize. sad

If I have helped great. biggrin

If you have questions, remember I just bullied my way through this whole thing using tenacity as my primary weapon; so I don't know much but I will try to explain mine more if you ask.

Re: Network problem

Well … at long last I am not alone in my „strange network config”! Bet there are a couple of other guys out there who don’t want to admit to what they have wired up at home wink

I have done everything to the book – i.e. the main ethernet card is configured in accordance with the internet providers guidelines and works perfect. No problems here.

The second card that runs bridge is configured is configured as follows:

Card id: 00-11-1E-11-0B-9F
Local IP: 192.168.0.1
Subnet mask: 255.255.255.0
Default gate: 192.168.0.1
DNS server: 192.168.0.1,
Alternative dns: 4.2.2.2
Serwer WINS:



I have all the other PCs (including one laptop) exactly the same except for local IP address which has a different last digit i.e. 192.168..0.2, 192.168.0.3 etc….The rest is identical (except for the card id of course)

….. but for all you that are afraid of networks – it is not a network problem. Why not?

1. I finally decided to install the Agent on my laptop and connected into the network instead of PC#2 – the trouble maker. It works fine!
2. Then having disconnected PC#2 from the network, I switched it on and the agent started crunching data when all of a sudden – bang agent rests and tries to connect to the server to pull down new data !!!!!!!!!!!

So we have the culprit. Went to the micrsoft site – pulled down the memory test – and Bills your Uncle! Memory problem that is not consistent. Comes and goes and is only identified by the intensive test. I have swapped out one of the memory banks to identify which one is the culprit. …… so fingers crossed.

Will let you know what happens next…… as the plot thickens but narrows down to the unpredictable 256Meg of RAM being molested at present by Bill!

Re: Not a Network problem

Great!! And I have had another embarassing lesson in isolating the problem. smile

Re: Not a Network problem

mycrofth .... you have kept me going through this feet of memory vengeance.... thankyou for the encouragement and ...just being there when I asked for help! .... that support was worth as much as the support that the Apollo 13 team got - knowing that they were not alone in dealing with their problem!

... but all problems are not resolved yet!

My laptop is crunching data at a CPU temp of 70 degrees Centegrade..... fans blowing like mad, hard disc stopped, power supply red hot and who knows what else is happening. I wonder how it will last before it pops!

Is this usual for a laptop to run this hot? The processor is a pentium 4 and I can imagine that it is getting the beating of its life - up till now, there were huge memory hungry spreadsheets and lots of power point stuff..... that is all. Suddenly all this math - I wonder how long it will withstand this wink

Re: Not a Network problem

Very interesting. So there was not a connection but rather happenstance where the agent on the first machine finished and it just happened that the #2 machine failed simultaneously. Things like that send you down the wrong path. crying

As to the configuration. I wired things that way due to the convenience. Notice that there is but one firewall machine. The others all communicate with each other and share things without the usual firewall headaches. Of course, it does not keep bad programs on the inside machines from phoning home..except on the "#1" machine but it does protect them all from intrusions. Actually I like this setup much better than the alternative...which is to connect the router to the internet and then have the other machines all have firewalls. Hum I just thought of another possibility ... this one is going to give me a headache.

As to the overheating P4 Laptop, I have one that I keep running at about 50% (using Toshiba utilities) just to avoid that problem. Sorry I can't help there.

Re: Not a Network problem

Yes coincidence led all down the wrong path.....

Mine is a Toshiba too.... I have just been looking at the Toshiba utilities and was wondering if I should do the same. It is really quite amazing - I stopped the agent and the temperature dropped from 71 to 42 within 3 minutes. Started the Agent and the temperature shot up just about vertically! The Toshiba reacts quickly though. The heat sink temp goes up with minimal time delay and the fan comes on quickly - seems to react to the speed of change in temperature as well as the current temperature - clever that.

.... Off to grab some ZZZZZZs.... take care all of you.
