Unable to get PXE menu?
-
@Quazz He only needs it if he’s trying to resolve hostnames.
-
Do I need a TFTP config in DHCPD.conf? It looks like I’m getting an IP during PXE then it stops at TFTP?
-
@mikepel TFTP In the isc-dhcp shouldn’t be required.
What happens if you restart the tftp service on the fog server? (
sudo service tftpd-hpa stop; sleep 2; sudo service tftpd-hpa start) (Does it restart or fail, and if it succeeds can fog work now?) -
Here is another pic of the PXE boot.
-
I ran the command.
stop: unknown instance:
tftpd-hpa start/running, process 25705 -
@mikepel Is it working now?
-
@Tom-Elliott No FOG menu again. Same thing as before. I’m uploading a video of what happened to provide some more screenshots…it gets stuck at configuring net (net0: macaddress)… then reboots
-
@mikepel Well is your switch setup for STP? Seeing as it’s a separated switch and you’re setup is currently in “Isolated mode” can you simply disable STP?
-
@Tom-Elliott I’ll try to get into the switch. I was told there isn’t a config on it, this might take some time to do.
-
@mikepel What type of switch is it?
-
@Tom-Elliott Its a Catalyst 2950. It was donated from an Air Force Base…so I’d hope it has a wiped config. Know of any Linux programs to console into switches? Is there a putty for linux?
-
@mikepel there’s ssh. Console may require a windows system as I don’t know of any command based terminal access via console stuff. That’s not to say there aren’t any, I just don’t know of one off the top of my head.
-
@Tom-Elliott Still working on getting into the config. Had to use an old XP laptop, only thing I could find with a serial port.
-
It looked like it was a clean config, just to be sure I wiped it again. I don’t think its anything with the switch config…Maybe I should try to rebuild the FOG server from scratch again.
-
@mikepel I don’t have the manual for that switch, but MANY cisco switches automatically enable stp by default.
-
@Tom-Elliott haha ugh. okay I just put all the console cable stuff away. I did find a USB to console cable so I can use my main PC now at least. I’ll disable it if it’s on by default.
-
Okay spanning-tree is disabled now…now I’m getting something different! TFTP timeout…

@mikepel as you’re on a switch you need to enable an ip-helper to tell the switch to redirect dhcp requests to your fog server.
-
@mikepel please try to post a photo of where the tftp timeout is occurring. If it’s during PXE it’s the iphelper thing, if it’s from iPXE it’s something else.
-
@Tom-Elliott …that was in my OP! I know on SCCM we had to do that which is why I asked.
