Unable to get PXE menu?
-
@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.
-
-
ip address helper should point to the DHCP server (in my case the same server where FOG is running)?
-
@mikepel Correct, but I’m still wanting to know WHERE the tftp timeout is coming from. Is it coming from iPXE (initializing) or is it coming from PXE with a PXE-E32 error?
-
@Tom-Elliott PXE-E32 error.
-
@mikepel Yep, then we need the ip-helper setup.
-
That PXE-E32 error happened after i setup the IP-Helper (and before). I’m only a help desk tech, I very rarely deal with network switch configs so it might not be configured right. I set it for VLAN 1 and all switch ports are on VLAN 1. Is that okay? I will get a copy of the config in a few minutes…

@mikepel All looks to be right, but can you just run another (
sudo service tftpd-hpa stop; sleep 2; sudo service tftpd-hpa start) again? It appears dhcp is working now, but tftp literally is not working at this point.
