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

Nous allons faire en sorte que MultideskOS et surtout ses outils de
cryptage/décryptage soient remis à jour régulièrement, car la sécurité
est mieux assurée ainsi. Exemple, nous mettons MultideskOS sur le net le
30 juin 2002, vous codez vos fichiers avec MultideskOS, trois semaines
plus tard, un pirate informatique parvient à les décoder, pas grave ! Le
temps qu'il trouve comment les fichiers sont codés, une nouvelle
combinaison de codage est déjà sortie ! Les fichiers déjà codés avec
l'ancienne version seront recodés avec la nouvelle version
automatiquement. Le travail ne doit être fatiguant QUE pour les pirates
informatiques !
