NAME

       ltsp dnsmasq - configure dnsmasq for LTSP

SYNOPSIS

       ltsp [ltsp-options] dnsmasq [-d dns] [-p proxy-dhcp] [-r real-dhcp] [-s dns-server] [-t tftp]

DESCRIPTION

       Install /etc/dnsmasq.d/ltsp-dnsmasq.conf, while adjusting the template with the provided parameters.

OPTIONS

       See the ltsp(8) man page for ltsp-options.

       -d, --dns=0|1
              Enable  or  disable  the  DNS  service. Defaults to 0.  Enabling the DNS service of dnsmasq allows
              caching of client requests, custom DNS  results,  blacklisting  etc,  and  automatically  disables
              DNSStubListener in systemd-resolved on the LTSP server.

       -p, --proxy-dhcp=0|1
              Enable  or  disable  the proxy DHCP service. Defaults to 1.  Proxy DHCP means that the LTSP server
              sends the boot filename, but it leaves the IP leasing to an external DHCP server,  for  example  a
              router  or  pfsense  or  a  Windows  DHCP  server. It's the easiest way to set up LTSP, as it only
              requires a single NIC with no static IP, no need to rewire switches etc.

       -r, --real-dhcp=0|1
              Enable or disable the real DHCP service. Defaults to 1.  In dual NIC  setups,  you  only  need  to
              configure  the internal NIC to a static IP of 192.168.67.1; LTSP will try to autodetect everything
              else.  The real DHCP service doesn't take effect if your IP isn't 192.168.67.x, so there's no need
              to disable it in single NIC setups unless you want to run isc-dhcp-server on the LTSP server.

       -s, --dns-server="space separated list"
              Set the DNS server DHCP option. Defaults to autodetection.  Proxy DHCP clients don't receive  DHCP
              options,  so  it's  recommended to use the ltsp.conf DNS_SERVER parameter when autodetection isn't
              appropriate.

       -t, --tftp=0|1
              Enable or disable the TFTP service. Defaults to 1.

EXAMPLES

       Create a default dnsmasq configuration, overwriting the old one:

              ltsp dnsmasq

       A dual NIC setup with the DNS service enabled:

              ltsp dnsmasq -d1 -p0 --dns-server="0.0.0.0 8.8.8.8 208.67.222.222"
