rpsl2acl - create a list of CIDRs from RPSL database


rpsl2acl [options]


Rpsl2acl queries a set of RPSL objects from a whois server, extracts members: records and converts them into a list of non-overlapping CIDR values. The resulting list is sorted lexicographically.


The following option control the output:

Format output as a bind ACL statement with the given name.


Print string as the heading comment to the output. The argument can consist of multiple lines. A "#" sign will be printed before each of them.

--outfile= FILE , -o FILE

Write the result to FILE , instead of the default "netlist".

The following options control selection of RPSL objects and initial contents of the output list:

Add given CIDRs to the output list. Argument is a comma-separated list of CIDRs.

--from-file= FILE , -T FILE

Populate the output list with CIDRs read from FILE . The file must list each CIDR on a separate line. Empty lines and comments (introduced by "#" sign) are ignored.

--objects=objlist, -r objlist

Defines a list of objects to query. Objlist is a comma-separated list of RPSL object names.

The following options control TCP connections:

Disable persistent connection. Rpsl2acl will open a new connection to the whois server for each RPSL object it is about to query.


Query this server, instead of the default "whois.ripe.net".

Options controlling log and debug output:
= FILE , -l FILE

Write diagnostic output to FILE , instead of standard error.

--debug[=spec[,spec...]], -d[spec[,spec...]]

Set debugging level. spec is either category or category=level, category is a debugging category name and level is a decimal verbosity level. Valid categories are: "GENERAL" and "WHOIS".

--dry-run, -n

Don’t create output file. Instead print the result on the standard output.

Informational options:
, -h

Show a terse help summary and exit.


Prints the manual page and exits.


The program reads its configuration from one of the following locations:
File name given by "RPSL2ACL_CONF" environment variable (if set)
b. ~

First of these files that exists is read. It is an error, if the $RPSL2ACL_CONF variable is set, but points to a file that does not exist. It is not an error if $RPSL2ACL_CONF is not set and neither of the two remaining files exist. It is, however, an error if any of these file exists, but is not readable.

The configuration file uses usual UNIX configuration format. Empty lines and UNIX comments are ignored. Each non-empty line is either an option name, or option assignment, i.e. opt=val, with any amount of optional whitespace around the equals sign. Valid option names are the same as long command line options, but without the leading --. For example:

objects = RS-FOO,RS-BAR,RS-BAZ
aclname = mynets
add-network =
outfile = networks.inc



The name of the configuration file to read, instead of the default /etc/rpsl2acl.conf.
