PXE Boot process/trouble shooting
Hello all, at the moment, I am looking at the automated kickstart and PXE boot functionality. My boot is stuck somewhere but I cannot spot anything in the logs or what/where something is supposed to happen. Can you please assist me in troubleshooting? This is where I am at (CentOS Uyuni Server): 1. Kickstartable tree is downloaded (via reposync). 2. Distribution is set up via WebUI. (Tree path=/var/spacewalk/rhn/kickstart/1/centos8-baseos-x86_64 and it exists on the file system for apache:apache). 3. Basic Profile created via WebUI ("kickstart-profile", OS seems OK, "Available tree" as in 2., software URL: /ks/dist/org/1/centos8-baseos-x86_64 ) 4. DHCP set up Now starting up a server: 5. PXE picked up DHCP. 6. PXE loaded the blue Cobbler menu Here, I can chose "kickstart-profile:1:test" 7. Now, whenever that entry is selected, the blue screen flashes and I am pretty much at the same place as 6. Pressing tab to see the boot details, these lines are shown: /images/centos8-baseos-x86_64:1:test/vmlinuz initrd=/images/centos8-baseos-x86_64:1:test/initrd.img ks=http://dev2.bluhm-de.com/cblr/svc/op/autoinstall/profile/kickstart-profile:1... BOOTIF=01-00-0a-21-31-56-34 wget http://dev2.bluhm-de.com/cblr/svc/op/autoinstall/profile/kickstart-profile:1... BOOTIF=01-00-0a-21-31-56-34 wget http://server/images/centos8-baseos-x86_64:1:test/vmlinuz wget http://server/images/centos8-baseos-x86_64:1:test/initrd.img All download content. Also firewall is disabled. So I am not really sure what exactly is supposed to happen when you press [enter] at step 6 above. What would be the real next step? Download a file? Boot an already downloaded file? Any hints for debugging would be great. Thank you and best wishes, Stefan
Thank you, got it. TFTP permission issue. Strangely the TFTP log only shows successful requests. Unsuccessful ones are only shown via a --verbose switch. ----- Ursprüngliche Mail ----- Von: "Stefan Bluhm" <opensuse.org@bluhm-de.com> An: "uyuni-devel" <uyuni-devel@opensuse.org> Gesendet: Samstag, 23.
