GNUNET-NAT-SERVER(1) General Commands Manual GNUNET-NAT-SERVER(1) NAME gnunet-nat-server -- help GNUnet setup test network setup with NAT SYNOPSIS gnunet-nat-server [-c FILENAME | --config=FILENAME] [-d | --daemonize] [-h | --help] [-L FILENAME | --logfile=FILENAME] [-v | --version] <PORT> DESCRIPTION Running a gnunet-nat-server is similar to running a hostlist server: it is a special service to the community with special requirements and no benefit to those running the service. This program will listen on the specified PORT for incoming requests to test a peer's network connectivity. Incoming requests can ask it to con- nect to a given IPv4 address (and port) using TCP or UDP and to send a 2-byte test message using the specified address. The program can also be asked to send a "fake" ICMP response message to a given IPv4 address (for autonomous NAT traversal --- see the description in the respective research paper). The idea is that gnunet-nat-server will be run on some trusted hosts with unrestricted connectivity to allow GNUnet users to test their network con- figuration. As written, the code allows any user on the Internet to cause the gnunet-nat-server to send 2-bytes of arbitrary data to any TCP or UDP port at any address. We believe that this is generally harmless. When running gnunet-nat-server, make sure to use a configuration that dis- ables most NAT options but enables 'enable_nat_client' and sets 'inter- nal_address' to the global IP address of your local host. Also, the gnunet-helper-nat-client should be installed locally and run with root privileges (SUID), otherwise the gnunet-nat-server will not work properly. Note that gnunet-nat-server could be run via gnunet-arm but typically is not. Also, the name of the host and port that gnunet-nat-server is run on should be specified in the NATSERVER option in the [setup] section of the configuration file of hosts that are supposed to autoconfigure with this server. Normal GNUnet end-users should not concern themselves with gnunet-nat- server. In fact, distributions are encouraged to consider not shipping it at all. The options are as follows: -c FILENAME | --config=FILENAME Use the configuration file FILENAME. -d | --daemonize Daemonize gnunet-nat-server (detach from terminal). -h | --help Print the help page. -L LOGLEVEL | --log=LOGLEVEL Configure logging to use LOGLEVEL. -l FILENAME | --logfile=FILENAME Configure logging to write logs to FILENAME. -v | --version Print the GNUnet version. SEE ALSO gnunet-transport(1) The full documentation for gnunet is maintained as a Texinfo manual. If the info(1) and gnunet programs are properly installed at your site, the command info gnunet should give you access to the complete handbook, info gnunet-c-tutorial will give you access to a tutorial for developers. Depending on your installation, this information is also available in gnunet(7)and gnunet-c-tutorial(7).
