Unable to get PXE menu?
-
@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…
Here is the switch config…ImageServerSwitch#show run Building configuration...

@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. -
@Tom-Elliott Will Ubuntu go into sleep mode like Windows does? I haven’t touched it in about an hour and it looks like it may have shutdown? Could be why it wasn’t working after the iP helper command…I restart the Ubuntu server, started TFTP and DHCP and I booted the PC and I finally have the FOG menu! WOOHOO Tom, Thank you so much for the help today. Literally so happy to get to this point, now just need to learn how to capture and deploy images! So the things I changed today were the netmask (don’t think this mattered), added an IP helper address and disabled spanning tree. Is the IP helper/spanning tree documented in tutorials anywhere? I don’t think the one I followed mentioned any of that. Anyways, thanks so F’ing much for the help!
-
@mikepel I don’t know how you installed Ubuntu, but I’m going to guess you installed it with a GUI?
The link should give you some info on how to prevent complete standby. I don’t think display sleep is a problem, but if the system goes out, when it comes back the services are likely not able to see the network (which would cause them to fail).
-
@Tom-Elliott Okay, I’ll look into all this. Just happy to be able to get PXE to work! Again, thanks.
