PXE-E32: TFTP open time out on palo alto dhcp server

[george1421]

@joanmarzo Sorry its not running. Use systemctl enable dnsmasq and then systemctl start dnsmasq to start it. When you do, there will be a second line to the ps command. If it still not running then we need to look at the server log to see what it’s not happy about grep dnsmasq /var/log/messages or grep dnsmasq /var/log/syslog to see of it complains about your ltsp.conf file. I did not see anything wrong with it but I maybe missed something too.

I try to initiate the dnsmasq but it doesn’t work

@joanmarzo Well we know why it not work. So when you install FOG server did you tell it to install dhcp server? For some reason dnsmasq can’t start because dhcp server already is running on the fog server. DNSMASQ failed because it says you have dhcp server already running on this computer.

I think you are using ubuntu from the screen shots I see already. The command to stop the dhcp server might be. See if this command will stop the dhcp server running on the fog server. If you have palo alto dhcp server on your network then having 2 dhcp servers will cause problems. systemctl stop isc-dhcp-server then try to start dnsmasq. If it starts OK then you can disable isc dhcp server with this command systemctl disable isc-dhcp-server

Once you see dnsmasq running then pxe booting should work.

@george1421 I use Centos7

[george1421]

@joanmarzo OK so I’m a bad guesser for operating systems.

For Centos you use these commands.

systemctl stop dhcpd to stop the dhcp server

systemctl disable dhcpd to make it not start on next reboot.

@joanmarzo looks good now. The ps aux | grep dnsmasq now should give you two lines. That means its running. You will see the line with grep in it, but you should also see a line that starts dnsmasq.
