# ipsec\_verify(8)

see if the IPsec subsystem has been installed correctly

## NAME

ipsec\_verify - see if the IPsec subsystem has been installed correctly

## SYNOPSIS

**ipsec** *verify*

## DESCRIPTION

The *ipsec verify* examines the local system for a number of common system faults and configuration mistakes.

## HISTORY

Written originally for the Linux FreeS/WAN project \<**https://www.freeswan.org**\> by Michael Richardson. Rewritten in python by Paul Wouters

## BUGS

*Verify* was converted from shell to perl to python, and the MASQUERADING/NAT rule tests still need to be ported. The *ss* command is around in various non-intuitive and buggy versions, causing some false-positives with respect to listening on UDP port 500 and 4500. See https://bugzilla.redhat.com/show\_bug.cgi?id=829630
