.SH DESCRIPTION
|
|
.B rblcheck
|
|
is a simple command-line to perform DNSBL (DNS-based blocklists) lookups.
|
|
For every IP address (or a name, in which case it will be resolved to an
|
|
address first), the utility verifies whenever it is listed in a (list of)
|
|
DNS blocklists specified with
|
|
.B \-s
|
|
or
|
|
.B \-S
|
|
options, optionally obtains text assotiated with the listing (usually it
|
|
is either some description about the reason of the listing or an URL
|
|
referring to such a description), and displays results on standard output.
|
|
.PP
|
|
The program is implemented on top of
|
|
.BR udns (3)
|
|
library.
|
|
|
|
.SH OPTIONS
|
|
|
|
The following options are recognized by
|
|
.BR rblcheck :
|
|
|
|
.TP
|
|
.B \-s \fIzone\fR
|
|
add the given \fIzone\fR DNSBL name to the list of active zones.
|
|
.TP
|
|
.B \-S \fIzone-file\fR
|
|
add list of zones from the named \fIzone-file\fR to the list of
|
|
active zones (the file specifies one zone as the first word on a
|
|
line, empty lines and lines starting with `#' character are ignored).
|
|
.TP
|
|
.B \-c
|
|
reset active zone list.
|
|
.TP
|
|
.B \-v
|
|
be more verbose, produce more detailed output.
|
|
.TP
|
|
.B \-q
|
|
the opposite for \fB\-v\fR -- produce less detailed output.
|
|
.TP
|
|
.B \-t
|
|
obtain text for listed addresses.
|
|
.TP
|
|
.B \-n \fInsaddr\fR
|
|
Use the given nameserver (given as IPv4 or IPv6 address) instead of the
|
|
default. The same effect may be achieved by setting $NSCACHEIP environment
|
|
variable.
|
|
.TP
|
|
.B \-m
|
|
stop after first hit, ie after the first address which is found to be
|
|
listed.
|
|
|
|
.TP
|
|
.B \-h
|
|
print short help and exit.
|
|
|
|
.PP
|
|
If no
|
|
.BR \-s ,
|
|
.BR \-S
|
|
and
|
|
.B \-c
|
|
options are given,
|
|
.B rblcheck
|
|
will try to obtain list of zones using $RBLCHECK_ZONES environment variable,
|
|
or ~/.rblcheckrc, or /etc/rblckechrc files, in that order. If no zones are
|
|
found, it will exit unsuccessefully.
|
|
|
|
.SH "RETURN VALUE"
|
|
When no addresses given are listed and no errors occured,
|
|
.B rblcheck
|
|
exits with code 0. If at least one address is listed,
|
|
.B rblcheck
|
|
returns 100. In case of DNS errors,
|
|
.B rblcheck
|
|
returns 2.

.B $RBLCHECK_ZONES
|
|
if no
|
|
.BR \-s ,

.B \-S
|
|
or
|
|
.B \-c

|
|
.B rblcheck
|

will try the two files (the first one that exists) to obtain list of
