RPKI-CLIENT(8) System Manager's Manual RPKI-CLIENT(8) NAME rpki-client -- RPKI validator to support BGP routing security SYNOPSIS rpki-client [-0ABcjmnoRVvx] [-b sourceaddr] [-d cachedir] [-e rsync_prog] [-H fqdn] [-P posix-seconds] [-p threads] [-S skiplist] [-s timeout] [-t tal] [outputdir] rpki-client [-Vv] [-d cachedir] [-j] [-t tal] -f file ... DESCRIPTION The rpki-client utility queries the Resource Public Key Infrastructure (RPKI) repository system with a built-in HTTPS client and rsync(1) to fetch all X.509 certificates, manifests, and revocation lists under a given Trust Anchor. rpki-client subsequently validates each Signed Object by con- structing and verifying a certification path for the certificate associated with the Object (including checking relevant CRLs). rpki-client produces lists of the Validated ROA Payloads (VRPs), BGPsec Router Keys (BRKs), and Validated ASPA Payloads (VAPs) in various formats. The options are as follows: -0 Include hazardous AS0 TALs in the output files. AS0 TALs are not recommended for automatic filtering of BGP routes. The default is not to include them. -A Exclude the ASPA-set from the output files that support it (BIRD, JSON, and OpenBGPD). -B Create output in the file bird in the output directory suitable for BIRD internet routing daemon version 2.16 and up. For compatibil- ity with earlier versions, use -A. The validated payload table names are ROAS4, ROAS6, and ASPAS. -b sourceaddr Tell the HTTP and rsync clients to use sourceaddr as the source ad- dress for connections, which is useful on machines with multiple interfaces. -c Create output in the file csv in the output directory as comma-sep- arated values of the Autonomous System, the prefix in slash nota- tion, the maximum prefix length, an abbreviation for the Trust Anchor the entry is derived from, and the moment the VRP will ex- pire derived from the chain of X.509 certificates and CRLs in sec- onds since the Epoch, UTC. -d cachedir The directory where rpki-client will store the cached repository data. Defaults to /var/cache/rpki-client. -e rsync_prog Use rsync_prog instead of rsync(1) to fetch repositories. It must accept the -rt and --address flags and connect with rsync-protocol locations. -f file ... Attempt to decode and validate the signed RPKI object or CCR in file using the cache stored in cachedir and print human-readable information about the object. Gzip compressed files are inflated on the fly. If file is an rsync:// URI, the corresponding file from the cache will be used. This option implies -n, and can be combined with -j to emit a stream of Concatenated JSON. This op- tion is intended for debugging. -H fqdn Create a shortlist and add fqdn to the shortlist. rpki-client only connects to shortlisted hosts. The shortlist filter is enforced during processing of the Subject Information Access (SIA) extension in CA certificates, thus applies to both RSYNC and RRDP connec- tions. This option can be used multiple times. -j Create output in the file json in the output directory as JSON ob- ject. See -c for a description of the fields. -m Create output in the file metrics in the output directory in Open- Metrics format. -n Offline mode. Validate the contents of cachedir and write to outputdir without synchronizing via RRDP or RSYNC. -o Create output in the file openbgpd in the output directory as bgpd(8) compatible input. If the -B, -c, and -j options are not specified this is the default. -P posix-seconds Specify the time for the evaluation in posix-seconds seconds from the unix epoch. This overrides the default of using the current system time. -p threads Validate using the specified number of threads. The default is two. Has no effect in combination with -f. -R Disable RRDP, synchronize only via RSYNC. -S skiplist Do not connect to hosts listed in the skiplist file. Entries in the skiplist are newline separated Fully Qualified Domain Names (FQDNs). A `#' indicates the beginning of a comment; characters up to the end of the line are not interpreted. The skip filter is en- forced during processing of the Subject Information Access (SIA) extension in CA certificates, thus applies to both RSYNC and RRDP connections. By default load entries from /usr/local/etc/rpki/skiplist. -s timeout Terminate after timeout seconds of runtime, because normal practice will restart from cron(8). Disable by specifying 0. Defaults to 1 hour. Individual RSYNC/RRDP repositories are timed out after one fourth of timeout. All network synchronisation tasks are aborted after seven eights of timeout. -t tal Specify a Trust Anchor Locator (TAL) file to be used. This option can be used multiple times to load multiple TALs. By default rpki-client will load all TAL files in /usr/local/etc/rpki. TAL are small files containing a public key and URL endpoint address. -V Show the version and exit. -v Increase verbosity. Specify once for synchronisation status, twice to print the name of each file as it's processed. If -f is given, specify once to print more information about the encapsulated X.509 certificate, twice to print the certificate in PEM format. -x Enable processing of experimental file formats. This option is im- plied by -f. outputdir The directory where rpki-client will write the output files. De- faults to /var/db/rpki-client. By default rpki-client outputs validated payloads in -joBcm (JSON, Open- BGPD, BIRD, CSV and OpenMetric) formats and in canonical cache representa- tion format. rpki-client should be run hourly by cron(8): use crontab(1) to uncomment the entry in root's crontab. TRUST ANCHOR CONSTRAINTS rpki-client can impose locally configured constraints on cryptographic products subordinate to publicly-trusted Trust Anchors. Constraining a Trust Anchor's effective signing authority to a limited set of Internet Number Resources allows Relying Parties to take advantage of the potential benefits of assuming trust, while deriving trust within a bounded scope. Each .constraints file imposes constraints on the Trust Anchor reachable via the same-named .tal file. One entry per line. Entries can be IP pre- fixes, IP address ranges, AS identifiers, or AS identifier ranges. Ranges are a minimum and maximum separated by a hyphen (`-'). Comments can be put anywhere in the file using a hash mark (`#'), and extend to the end of the current line. deny entries may not overlap with other deny entries. allow entries may not overlap with other allow entries. A given EE certificate's resources may not overlap with any deny entry, and must be fully contained within the allow entries. ENVIRONMENT rpki-client utilizes the following environment variables: http_proxy URL of HTTP proxy to use. FILES /usr/local/etc/rpki/*.tal default TAL files used unless -t tal is spec- ified. The TAL files of the five Regional Internet Registries are included. /usr/local/etc/rpki/*.constraints files containing registry-specific con- straints to restrict what IP addresses and AS identifiers may or may not appear in EE cer- tificates subordinate to the same-named Trust Anchor. /usr/local/etc/rpki/skiplist default skiplist file, unless -S skiplist is specified. /var/cache/rpki-client cached repository data. /var/db/rpki-client/openbgpd default roa-set output file. /var/db/rpki-client/rpki.ccr DER-encoded canonical cache representation file. This facility is experimental and is still subject to change. EXIT STATUS The rpki-client utility exits 0 on success, and >0 if an error occurs.
