### Testing
Changes can be tested by using [Packer](https://www.packer.io/) and
[vmm(4)](https://man.openbsd.org/vmm.4) :
* This process depends on the [Go](https://golang.org/) programming language.
**Packages**
Needing a Golang eco system and some basics
````
pkg_add go-- packer-- git--
````
* We use the [packer-builder-openbsd-vmm](https://github.com/double-p/packer-builder-openbsd-vmm) project to bridge Packer and vmm(4)
````
git clone https://github.com/double-p/packer-builder-openbsd-vmm.git
````
**builds**
Set ````GOPATH```` (default: ~/go), if the 1.4GB dependencies wont fit.
````
make
make install
````
* You need your unprivileged user to be able to run vmctl(8) through doas(1)
```
echo "permit nopass myunprivilegeduser as root cmd /usr/sbin/vmctl" >> /etc/doas.conf
```
See packer-builder-openbsd-vmm/examples/README.examples for further instructions
* Enable NAT on your host machine
```
pass out on em0 inet from tap0:network to any nat-to (em0)
```
*assuming em0 is your egress interface*

# logcheck.sh: Log file checker
# Written by Craig Rowland <crowland@psionic.com>
#
# This file needs the program logtail.c to run
#
# This script checks logs for unusual activity and blatant
# attempts at hacking. All items are mailed to administrators
# for review. This script and the logtail.c program are based upon
# the frequentcheck.sh script idea from the Gauntlet(tm) Firewall
# (c)Trusted Information Systems Inc. The original authors are
# Marcus J. Ranum and Fred Avolio.
#
# Default search files are tuned towards the TIS Firewall toolkit
# the TCP Wrapper program. Custom daemons and reporting facilites
# can be accounted for as well...read the rest of the script for
# details.
#
# Version Information
#
# 1.0 9/29/96 -- Initial Release
# 1.01 11/01/96 -- Added working /tmp directory for symlink protection
# (Thanks Richard Bullington (rbulling@obscure.org)
# 1.1 1/03/97 -- Made this script more portable for Sun's.
# 1/03/97 -- Made this script work on HPUX
# 5/14/97 -- Added Digital OSF/1 logging support. Big thanks
# to Jay Vassos-Libove <libove@compgen.com> for
# his changes.
# CONFIGURATION SECTION
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin
# Logcheck is pre-configured to work on most BSD like systems, however it
# is a rather dumb program and may need some help to work on other
# systems. Please check the following command paths to ensure they are
# correct.
# Person to send log activity to.
SYSADMIN=root
# Full path to logtail program.
# This program is required to run this script and comes with the package.
LOGTAIL=/usr/local/bin/logtail
# Full path to SECURED (non public writable) /tmp directory.
# Prevents Race condition and potential symlink problems. I highly
# recommend you do NOT make this a publically writable/readable directory.
# You would also be well advised to make sure all your system/cron scripts
# use this directory for their "scratch" area.
TMPDIR=/var/cache/logsentry
# The 'grep' command. This command MUST support the
# '-i' '-v' and '-f' flags!! The GNU grep does this by default (that's
# good GNUs for you Linux/FreeBSD/BSDI people :) ). The Sun grep I'm told
# does not support these switches, but the 'egrep' command does (Thanks
# Jason <jason@mastaler.com> ). Since grep and egrep are usually the GNU
# variety on most systems (well most Linux, FreeBSD, BSDI, etc) and just
# hard links to each other we'll just specify egrep here. Change this if
# you get errors.
# Linux, FreeBSD, BSDI, Sun, HPUX, etc.
GREP=egrep
# The 'mail' command. Most systems this should be OK to leave as is.
# If your default mail command does not support the '-s' (subject) command
# line switch you will need to change this command one one that does.
# The only system I've seen this to be a problem on are HPUX boxes.
# Naturally, the HPUX is so superior to the rest of UNIX OS's that they
# feel they need to do everything differently to remind the rest that
# they are the best ;).
# Linux, FreeBSD, BSDI, Sun, etc.
MAIL=mail
# HPUX 10.x and others(?)
#MAIL=mailx
# Digital OSF/1, Irix
#MAIL=Mail
# File of known active hacking attack messages to look for.
# Only put messages in here if you are sure they won't cause
# false alarms. This is a rather generic way of checking for
# malicious activity and can be inaccurate unless you know
# what past hacking activity looks like. The default is to
# look for generic ISS probes (who the hell else looks for
# "WIZ" besides ISS?), and obvious sendmail attacks/probes.
HACKING_FILE=/etc/logsentry/logsentry.hacking
# File of security violation patterns to specifically look for.
# This file should contain keywords of information administrators should
# probably be aware of. May or may not cause false alarms sometimes.
# Generally, anything that is "negative" is put in this file. It may miss
# some items, but these will be caught by the next check. Move suspicious
# items into this file to have them reported regularly.
VIOLATIONS_FILE=/etc/logsentry/logsentry.violations
# File that contains more complete sentences that have keywords from
# the violations file. These keywords are normal and are not cause for
# concern but could cause a false alarm. An example of this is the word
# "refused" which is often reported by sendmail if a message cannot be
# delivered or can be a more serious security violation of a system
# attaching to illegal ports. Obviously you would put the sendmail
# warning as part of this file. Use your judgement before putting words
# in here or you can miss really important events. The default is to leave
# this file with only a couple entries. DO NOT LEAVE THE FILE EMPTY. Some
# grep's will assume that an EMPTY file means a wildcard and will ignore
# everything! The basic configuration allows for the more frequent sendmail
# error.
#
# Again, be careful what you put in here and DO NOT LEAVE IT EMPTY!
VIOLATIONS_IGNORE_FILE=/etc/logsentry/logsentry.violations.ignore
# This is the name of a file that contains patterns that we should
# ignore if found in a log file. If you have repeated false alarms
# or want specific errors ignored, you should put them in here.
# Once again, be as specific as possible, and go easy on the wildcards
IGNORE_FILE=/etc/logsentry/logsentry.ignore
# The files are reported in the order of hacking, security
# violations, and unusual system events. Notice that this
# script uses the principle of "That which is not explicitely
# ignored is reported" in that the script will report all items
# that you do not tell it to ignore specificially. Be careful
# how you use wildcards in the logcheck.ignore file or you
# may miss important entries.
# Make sure we really did clean up from the last run.
# Also this ensures that people aren't trying to trick us into
# overwriting files that we aren't supposed to. This is still a race
# condition, but if you are in a temp directory that does not have
# generic luser access it is not a problem. Do not allow this program
# to write to a generic /tmp directory where others can watch and/or
# create files!!
# Shouldn't need to touch these...
