John, I had a problem with the DHCP not starting up when using Network Manager to set my static IP. Usually people use the /etc/network/interfaces file to get around this but I wanted to use Network Manager so I had access to VPN connections and such.
I found if I put my DHCP & tftp startup scripts into /etc/network/if-up.d then they start when my network is connected through Network Manager. Here is my script: /etc/network/if-up.d/dhcp3-server #! /bin/sh # Kick DHCP server when interface comes up (for Ubuntu, probably Debian too) # Workaround for <https://bugs.launchpad.net/ubuntu/+source/dhcp3/+bug/392826> # Bugs: # - Only works when interfaces for dhcpd are explicitly listed. DHCP_IF=/etc/default/isc-dhcp-server DHCP_INIT=/etc/init.d/isc-dhcp-server [ -f "$DHCP_IF" -a -f "$DHCP_INIT" ] || exit 0 . "$DHCP_IF" if [ "x$INTERFACES" = x ]; then # Don't know which interfaces it manages, always restart restart_dhcp=1 else restart_dhcp=0 for iface in "$INTERFACES"; do if [ "$iface" = "$IFACE" ]; then restart_dhcp=1 fi done fi if [ "$restart_dhcp" = "1" ]; then "$DHCP_INIT" restart sleep 10 /etc/init.d/tftp-hpa restart fi Make executable. Now test by disconnecting & re-connecting. from Michael On 10/08/12 05:59, John Hupp wrote: > > Thanks for that, Michael. > > Actually, further testing on this setup shows that it's not just TFTP > that sometimes fails.
