Hello,

I’m back with a new question!

I’m running Fog alongside my DHCP server (Windows Server 2012) and for some reason, TFTP keeps timing out at PXE boot.

I’ve captured traffic using Wireshark and it looks something like this:

Server sends data packet “Block 0” to client
Client tells server “Fragemented IP protocol”

Server sends data packet “Block 1” to client
Client tells server “Acknowledgement, Block: 0”

And this repeats until it times out. Just sending block 0 and 1 back and forth.

I’m completely lost and any help would be greatly appreciated!

Thanks!

Hello,

I’ve been posting a lot recently and I apologize but I am running out of time.

My latest issue is that whenever I attempt to upload an image, I get:
“RPC remote system error connection refused” and something similar to NFS share could no be mounted.

Does anyone have any ideas on how to solve this?

Thanks!

Physical PCs across multiple subnets (subnets other than what the DHCP server and the Fog server are on)

Hello,

I work in a lab environment that is controlled by a Windows Server 2012 DHCP server.
I currently have Fog installed on an Ubuntu 10.04 box and have been attempting to PXE boot off of it.
For some reason, I continually receive: “File not found” during PXE boot and am unable to proceed any further.

I have done (on another box): tftp [my server’s IP] and then get pxelinux.0 with success.

I don’t understand why my PC’s can’t PXE boot if I can pull the file manually.
In Server 2012, I have configured option 66 to my server’s IP and option 67 to pxelinux.0.

Any help would be [B]greatly[/B] appreciated!

Thank you!

It ended up being that all of my PCs were in AHCI mode when they needed to be in IDE. It’s all solved now! Thanks!

After doing some more testing, I’ve found that:

Host PC running a virtual machine, virtual machine will do EVERYTHING perfectly! No errors.
Same host PC will only do quick inventory. Can’t mount NFS because of RPC issue.

Why does a virtual machine work but the physical box does not when they are on the same exact subnet, port, everything?
The only difference is that I have IP reservations on my DHCP server for the physical boxes and not the virtual machines.

The error is: “RPC No Route to Host” whenever I attempt to mount the NFS share to upload an image.

There must be a reason as to why these computers can’t find their way back to the Fog server.

Well, I spoke too soon…

Last night, I was remoted into virtual machines on physical PCs in different subnets and that worked.

This morning, I tried to perform a full registration and image the physical PCs in different subnets and I am still getting the RPC error.

When I perform a quick registration, it works. When I perform a full registration, it just keeps trying to send the information but it never completes.

My DHCP server gave the virtual machines no reserved IP address where as my physical boxes get a reserved IP. Maybe that has something to do with it? Not sure.

I GOT IT!

I read this post earlier today and didn’t think much of it. Turns out, it fixed my issue.

I had to edit my.conf and change bind-address to my Fog server IP instead of 127.0.0.1.

Thank you so much, Tom! I couldn’t have fixed it without your support. I greatly appreciate it!

That’s something that I’ll look into! I’ll see what I can do tomorrow morning and hopefully, I’ll be able to get it working. I think that you’re right though. I’ll keep you posted on how it goes tomorrow!

There’s no internal firewall on the network and the Ubuntu Server that Fog is running off of has its firewall disabled.

I’m thinking about when I first installed Fog. It asks me what my router’s IP address was and I set it to the IP of my Windows DHCP Server.
