`tcpdmatch(8)` on Solnix vs Linux and the BSDs

On Solnix, tcpdmatch is the illumos tcp wrapper oracle at /usr/sbin/tcpdmatch. It has the same -d and -i options as FreeBSD and NetBSD. The differences are in the configuration files it mentions and in the pages' cross-references to SMF.

The manual pages

Solnix: tcpdmatch(8) from pkgs.solnix.illumos-world-man · illumos.org
FreeBSD: tcpdmatch(8) 15.1-RELEASE
NetBSD: tcpdmatch(8) 11.0

What Solnix runs

A default Solnix system runs the illumos tcpdmatch at /usr/sbin/tcpdmatch. No other variants are shipped. The page's SEE ALSO points to inetadm(8) for managing inetd services in the Service Management Framework.

Differences

Compared with	Topic	What differs
FreeBSD, NetBSD	network configuration file searched	The Solnix page says tcpdmatch extracts extra information from the inetd network configuration file only. FreeBSD and NetBSD say it reads an inetd or tlid configuration file. Source: Solnix tcpdmatch(8) DESCRIPTION; FreeBSD tcpdmatch(8) DESCRIPTION; NetBSD tcpdmatch(8) DESCRIPTION
FreeBSD, NetBSD	`-i` inet_conf	On Solnix, `-i` is for when tcpdmatch cannot find inetd.conf. FreeBSD and NetBSD say it is also for when tcpdmatch cannot find tlid.conf. The option letter and argument are the same on all three. Source: Solnix tcpdmatch(8) -i; FreeBSD tcpdmatch(8) -i; NetBSD tcpdmatch(8) -i
FreeBSD	tlid.conf reference	The FreeBSD SEE ALSO lists tlid.conf(5). The Solnix page does not. Solnix lists inetadm(8) instead. Source: FreeBSD tcpdmatch(8) SEE ALSO; Solnix tcpdmatch(8) SEE ALSO
all four	inetd under SMF	The Solnix page points to inetadm(8) for managing inetd services in the Service Management Framework, and to inetd(8) for invoking tcpd through libwrap. The FreeBSD and NetBSD pages do not mention either. Source: Solnix tcpdmatch(8) SEE ALSO; FreeBSD tcpdmatch(8) SEE ALSO; NetBSD tcpdmatch(8) SEE ALSO
NetBSD	known FQDN bug	The NetBSD page has a BUGS section. A fully qualified hostname given as the client is recognised only as an IPv4 or only as an IPv6 address, not both. The Solnix page has no BUGS section, so it does not say whether this applies. Source: NetBSD tcpdmatch(8) BUGS; Solnix tcpdmatch(8) (no BUGS section)
FreeBSD	SYNOPSIS section	The FreeBSD page text in the bundle has no SYNOPSIS section. Solnix and NetBSD document two forms: daemon client, and daemon[@server] [user@]client. Source: FreeBSD tcpdmatch(8) (no SYNOPSIS); Solnix tcpdmatch(8) SYNOPSIS; NetBSD tcpdmatch(8) SYNOPSIS
Linux	Linux	No Linux counterpart page is in the bundle, so the manual does not say how Linux compares. Source: Bundle header lists only FreeBSD and NetBSD counterparts

Standards

POSIX: tcpdmatch is not a POSIX.1-2024 utility.
Solnix: Interface Stability: Committed.

Writing portable scripts

Use only -d and -i inet_conf, which are the same on Solnix, FreeBSD and NetBSD. Pass -i explicitly if the inetd configuration file is not found.

Every difference here is taken from the manual pages linked above: Solnix's published page, Linux (man-pages and the GNU and util-linux manuals), FreeBSD, OpenBSD and NetBSD. Each row names its source. Where a manual is silent, this page is too. Compiled 2026-10-26. Found a mistake? Mail hackers@lists.solnix.io.
