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

On Solnix, ippool is the illumos IP Filter pool tool at /usr/sbin/ippool. Unlike the FreeBSD and NetBSD versions, it can target a zone with -z or -G, and it has -h to list hash pools. It has no -T (node expiry) and no -D (dump).

The manual pages

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

What Solnix runs

A default Solnix system runs the illumos ippool at /usr/sbin/ippool, published in pkgs.solnix.illumos-world-man. No other variants are shipped. The bundle has no Linux counterpart page.

Differences

Compared with	Topic	What differs
FreeBSD, NetBSD	zone selection (`-z`, `-G`)	Solnix ippool takes `-z` zonename (in-zone pools) or `-G` zonename (global-zone-controlled pools). Both are available only in the Global Zone. The FreeBSD and NetBSD pages have no zone options. Source: Solnix ippool(8) SYNOPSIS, Global Options -z, -G; FreeBSD ippool(8) SYNOPSIS; NetBSD ippool(8) SYNOPSIS
FreeBSD, NetBSD	`-h` lists hash pools	Solnix has `-h` to list pools of type hash, and `-l` lists tree pools. The FreeBSD and NetBSD pages have no `-h`. Their `-l` is filtered with `-t` type instead. Source: Solnix ippool(8) -h, -l; FreeBSD ippool(8) SYNOPSIS (-l); NetBSD ippool(8) SYNOPSIS (-l)
FreeBSD, NetBSD	`-t` pool type name	Solnix `-t` accepts pool, hash or group-map. FreeBSD and NetBSD accept tree, hash or group-map. A script passing `-t` tree is not valid by the Solnix page, although its `-l` is described as listing tree pools. Source: Solnix ippool(8) -t, -l; FreeBSD ippool(8) -t; NetBSD ippool(8) -t
FreeBSD, NetBSD	`-T` expiry missing	FreeBSD and NetBSD take `-T` ttl with `-a` to set the expiry of the added node, in seconds. The Solnix page documents no `-T` option. Source: FreeBSD ippool(8) -T, SYNOPSIS (-a); NetBSD ippool(8) -T, SYNOPSIS (-a); Solnix ippool(8) SYNOPSIS
FreeBSD	`-D` dump to stdout	FreeBSD `-D`, used with `-l`, dumps the pool configuration in a format usable as input to ippool `-f`. The Solnix page has no `-D` and does not describe a dump format. Source: FreeBSD ippool(8) -D; Solnix ippool(8) OPTIONS
FreeBSD	`-o` role values	Solnix accepts ipf, auth and count for `-o`. FreeBSD says only ipf (the default) is accepted. NetBSD matches Solnix. The Solnix page states no default role. Source: Solnix ippool(8) -o; FreeBSD ippool(8) -o; NetBSD ippool(8) -o
FreeBSD	`-t` required	In the FreeBSD synopsis, `-t` type is mandatory for `-A` and `-R`. In the Solnix and NetBSD synopses it is optional, in brackets, for both. Source: FreeBSD ippool(8) SYNOPSIS (-A, -R); Solnix ippool(8) SYNOPSIS (-A, -R); NetBSD ippool(8) SYNOPSIS (-A, -R)
FreeBSD	`-R` and repeated `-f`	The FreeBSD synopsis lists `-R` among the flags for `-f` and allows repeating `-f` file. Its OPTIONS section does not describe `-R` in that use. On Solnix, `-R` removes a pool and `-f` takes a single file. Source: FreeBSD ippool(8) SYNOPSIS (-f); Solnix ippool(8) SYNOPSIS (-f), -R
FreeBSD, NetBSD	`-M` and `-N` placement	Solnix and NetBSD list `-M` core and `-N` namelist under `-s`, the statistics mode. FreeBSD lists them under `-l` and shows none for `-s`. Source: Solnix ippool(8) SYNOPSIS (-s); NetBSD ippool(8) SYNOPSIS (-s); FreeBSD ippool(8) SYNOPSIS (-l, -s)
FreeBSD, NetBSD	root and device access	The Solnix page says the default permissions on /dev/ippool, /dev/ipauth, /dev/ipl and /dev/ipstate mean ippool must run as root for all operations. The FreeBSD and NetBSD pages do not say. Source: Solnix ippool(8) DESCRIPTION; FreeBSD ippool(8) DESCRIPTION; NetBSD ippool(8) DESCRIPTION

Standards

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

Writing portable scripts

Avoid -h, -z, -G, -T and -D in portable scripts: each exists on only some of Solnix, FreeBSD and NetBSD.
Pass -t explicitly with hash or group-map, which all three pages accept. The name of the third type differs: pool on Solnix, tree on FreeBSD and NetBSD.

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.
