ipseckey - Man Page

ipseckey

ipseckey generates RFC-4025 IPSECKEY DNS records based on the public key of the IPsec server. Supported IPsec software is libreswan and some versions of openswan (depending on its implementation of showhostkey). The record is displayed will have the label of the hostname. This can be manually changed.

(TODO: allow specifying --hostname and allow --reverse for creating in-addr.arpa. entries)

-h / --help

-v / --version

The NSS IPsec database in /etc/ipsec.d/*.db or for older openswan without NSS /etc/ipsec.secrets

ipseckey MUST be run on the IPsec gateway itself because unlike TLS, IPsec servers do not present their public RSA key any client. Currently, only libreswan IPsec is supported (https://libreswan.org) although some versions of openswan might work as well. Root access is needed because the public key is pulled from /etc/ipsec.secrets which can contain secrets and is therefor only readable by root (even though with libreswan, ipsec.secrets does not contain the any private RSA keys)

Some other IPsec software is not yet supported

ipsec_showhostkey(8) and RFC-4025
