iodine-client-start(8)


NAME

   iodine-client-start - start an iodine IPv4-over-DNS tunnel

SYNOPSIS

   iodine-client-start [option]

DESCRIPTION

   'iodine-client-start' starts an iodine IP-over-DNS tunnel.

   -h, --help
          Print help and exit

   -v, --version
          Print version info and exit

   Invoking  the  program without options attempts to set up and configure
   an iodine IP-over-DNS  tunnel  using  the  configuration  in  the  file
   /etc/default/iodine-client  or by querying the user. It tries to figure
   out the right way to set things up by observing the network, and if all
   else fails by guessing.

   QUICK CONFIGURATION

   Put two lines in the file /etc/default/iodine-client

          subdomain=your.tunnel.sub.domain

          passwd=password_for_that_tunnel

   or invoke the script with those environment variables set:

          env subdomain=xxx passwd=xxx iodine-client-start

   If these are not set, the script will query the user for them.

   DETAILS

   The  configuration  file  consists  of  lines which are either comments
   starting with '#', or settings of the form VAR="val". Valid VARs are:

   subdomain

          Sample value: your.tunnel.sub.domain (no default, must be set)

   passwd

          Sample value: password_for_that_tunnel (no default, must be set)

   testhost

          Hostname to ping when testing if network  is  working  (default:
          slashdot.org)

   bounce_localnet

          Take  the  local  network down and then up again before starting
          tunnel (default: false)

   test_ping_localnet

          Test if the local network is  working  by  pinging  the  gateway
          (default: true)

   test_ping_tunnel

          Test if the iodine tunnel is working after it has been set up by
          pinging the host at the other end (default: true)

   test_ping_final

          Test if the tunnel is working after everything is ostensibly set
          up by trying to ping an external host (default: true)

   default_router

          IP  address  of  router  on  the local network---should be found
          automatically, set this if that fails and  the  program  guesses
          wrong.

   interface

          Interface  to  use (e.g., eth1, eth0, etc) for connection to DNS
          server  used   for   the   iodine   tunnel---should   be   found
          automatically,  set  this  if that fails and the program guesses
          wrong.

   mtu

          Set if tunnel MTU needs to be manually changed (lowered). Should
          not be necessary anymore, as recent versions of iodine negotiate
          an appropriate MTU during tunnel setup. But if that  negotiation
          does not happen, or if you are using an older version of iodine,
          the default tunnel MTU is 1024, and  if  the  local  DNS  server
          restricts  to  512  byte packets you might need to use an MTU of
          220.

   skip_raw_udp_mode

          Set "-r" option in iodine command line. With this option, iodine
          does  not  try  to  establish  a direct UDP socket to the iodine
          server on port 53. (default: true).

   continue_on_error

          Set if the script should continue even if a command fails.   Use
          to  test  script  when running as non-root. Defaults to false if
          running as root, true otherwise.
