stunc - STUN test client. STUN test client Author: Pekka Pessi <Pekka.Pessi@nokia.com> Martti Mela <Martti.Mela@nokia.com> Kai Vehmanen <Kai.Vehmanen@nokia.com> Date: Created: Thu Jul 24 17:21:00 2003 ppessi Synopsis stunc [OPTIONS] <stun-server-address> Description The stunc utility can be used to gather information about possible NAT devices that are located between the client and STUN server. stunc can provide the following information: the IP address and port as seen by the STUN server, detecting presence of NATs, and hints on the type of address translation done. It should be noted that the results of NAT type and life-time detection should be considered as hints. There is no guarantee that NAT(s) will handle future packets in the same way. Command Line Options The stunc utility accepts following command line options: -b Perform a STUN binding discovery. stunc will report the client transport address (IP:port) as seen by the STUN server. In the presence of NATs, this address is allocated by the NAT closest to the STUN server. -l Perform a STUN binding life-time check. -n Perform a STUN binding type check. Notice that the results are only hints. Nondeterministic behaviour, resource exhaustion, or reboots of network elements can cause changes in NAT behaviour between successive runs of stunc. -r Randomize the local port. Otherwise stunc let's the operating system select a free port. -s Request a shared-secret over TLS. Tests whether the STUN server supports the shared-secret mechanism (needed to protect message integrity). Can be combined with -b, -l and -n. Return Codes 0when successful 1when any errors detected Examples Discover the NAT binding, use a random local port: $ stunc stunserver.org -b -r Environment #STUN_DEBUG Reporting Bugs Report bugs to <sofia-sip-devel@lists.sourceforge.net>.

sip-dig - Resolve SIP URIs. This is an example program for sresolv library in synchronous mode. Author: Pekka Pessi <Pekka.Pessi@nokia.com> Date: Original Created: Tue Jul 16 18:50:14 2002 ppessi Synopsis sip-dig [OPTIONS] uri... Description The sip-dig utility resolves SIP URIs as described in RFC 3263. It queries NAPTR, SRV and A/AAAA records and prints out the resulting transport addresses. The default transports are: UDP, TCP, SCTP, TLS and TLS-SCTP. The SIPS URIs are resolved using only TLS transports, TLS and TLS-SCTP. If not otherwise indicated by NAPTR or SRV records, the sip-dig uses UDP and TCP as transports for SIP and TLS for SIPS URIs. The results are printed intended, with a preference followed by weight, then protocol name, port number and IP address in numeric format. Command Line Options The sip-dig utility accepts following command line options: -p protoname Use named transport protocol. The protoname can be either well-known, e.g., 'udp', or it can specify NAPTR service and SRV identifier, e.g., 'tls-udp/SIPS+D2U/_sips._udp.'. --udp Use UDP transport protocol. --tcp Use TCP transport protocol. --tls Use TLS over TCP transport protocol. --sctp Use SCTP transport protocol. --tls-sctp Use TLS over SCTP transport protocol. --no-sctp Ignore SCTP or TLS-SCTP records in the list of default transports. This option has no effect if transport protocols has been explicitly listed. -4 Query IP4 addresses (A records) -6 Query IP6 addresses (AAAA records). -v Be verbatim. Return Codes 0when successful (a 2XX-series response is received) 1when unsuccessful (a 3XX..6XX-series response is received) 2initialization failure Examples Resolve sip:openlaboratory.net, prefer TLS over TCP, TCP over UDP: $ sip-dig --tls --tcp --udp sip:openlaboratory.net 1 0.333 tls 5061 212.213.221.127 2 0.333 tcp 5060 212.213.221.127 3 0.333 udp 5060 212.213.221.127 Resolve sips:example.net with TLS over SCTP (TLS-SCTP) and TLS: $ sip-dig -p tls-sctp --tls sips:example.net 1 0.500 tls-udp 5061 172.21.55.26 2 0.500 tls 5061 172.21.55.26 Environment #SRESOLV_DEBUG, SRESOLV_CONF Reporting Bugs Report bugs to <sofia-sip-devel@lists.sourceforge.net>.
