@Pikmin I don’t like guessing much so we should just take a look at the facts - the packets on the network that is. So get your client ready but don’t start it yet. Go to your FOG server and install tcpdump (
sudo apt-get install tcpdumpor
sudo yum install tcpdump). Then run the following command and substitute x.x.x.x with the client’s IP address: tcpdump -w /tmp/boot_issue.pcap host x.x.x.x
Leave that command sitting there, boot up the client till it shows the error “Either DHCP failed or …”. Now stop tcpdump (Ctrl+c). Upload the generated file /tmp/boot_issue.pcap to your dropbox/google drive and post a link here or send me a private message if you don’t want to share this with the rest of the world.
I just went through the process of doing this when I discovered that after issuing spanning-tree portfast on all the interfaces it appears to be working now, so that’s the solution like in the other thread.
Thanks again for all your help george1421 and Sebastian Roth, I won’t forget the porfast setting ever again
