Monitoring Fold-Server clients??

How do I monitor the progress of my Fold-Server clients? Currently I am still in the testing stages of setting up my farm, but things are going well. I have the Fold-Server configured. I am able to get to the Internet through eth1 and eth0 is netbooting a PXE client computer. I have a monitor hooked up to the PXE client just so I could watch it the netboot was working. It boots fine, but I think there might be some problems. The screen says this...

-Ask before connecting: No
-User name: mike400hp (Team 33)
-User ID not found locally
+Requesting User ID from server
-Couldn't send HTTP request to server
+Could not connect to Primary Assignment Server for ID
-Couldn't send HTTP request to server
+Could not connect to Secondary Assignment Server for ID

+Could not get ID from server. Retrying...

Anyone have an idea what could cause this? Once I get the client working, how do I monitor it's progress?
 
I'm back! Had a camping trip this weekend, so thus the long response time.

Have you added the static route to your router? Here and here are Crashsector's and my documentation, respectively. There is another method if you can't add a static route for whatever reason, email me for details.

HTH :D
 
I thought that might have been the problem, but this morning I added the static route and still no luck. Here is a screen shot from my Netgear MR814 router.

Can you ping from the client to the outside world? Log in to it (either plug in a keyboard/monitor, or do "ssh fold-clientXXX" where XXX is the number of the client) and try these:
nslookup google.com
ping google.com
If those don't work, you may need to configure /etc/resolv.conf on the server.

I believe you may also need to turn off the "private" option on that route; some routers, I'm finding, won't do NAT for anything off their subnet.
 
Should I change the Gateway address on eth0 from 10.1.1.1 to 192.168.1.1? 192.168.1.1 the router IP. How do I log into the client? Where can I find the client number? It never gives me a prompt and is netbooting. Linux noob remember :)
 
It automatically switches to the 5th console. Hit alt-f1 and you'll be at a login prompt. The password is "Fold@on". It'll tell you the client number at the login prompt.

As for changing the route, whatever fold-server's address is is what the gateway should be set to. It's acting as a gateway between the two networks.

By the Fold-Server's IP you mean the 192.168.1.15 that is on eth1?
 
Right. The router on the 192 network will then know how to talk to the clients. An explanation of why this is necessary is at the link I posted for my documentation.
 
Alright I have rebuild the Fold-Server and I'm still getting the orginial error that started this thread. I'm able to log into the 'fold-client57" as root and here is what I get:

~ # nslookup google.com
Server: fold-server
Address: 10.1.1.1

Name: google.com
Addresses: 216.239.37.99, 216.239.39.99, 216.239.57.99
~ # ping google.com
PING google.com (216.239.57.99): 56 data bytes

******didn't appear to be doing anything so I hit Ctrl+C********
--- google.com ping statistics ---
113 packets transmitted, 0 packets received, 100% packet loss
~ #

Looks like it's going out but not coming back.
 
Can you ping google from the server? If you can, then I'll need to email you some files. This will mean that the router is denying NAT to the 10 subnet and we'll make some changes on fold-server to fix that.

Did you turn off the "private" option for the static route? I haven't figured out whether Netgear routers just deny NAT to other networks altogether or if it's an optional thing. :confused:

Anyways, if you can ping out from the server, email me and I'll send instructions.
 
Now you have mail. :) I'm getting Permission Denied when i try to:

iptables -t nat -A POSTROUTING -o eth1 -j SNAT --destination 0.0.0.0/0 --to-source 192.168.1.15

thanks!
