== Notes on installing, confuguring and using OpenBSD ==

TO DO LIST

vim
lid suspend
shell environment
ftpd ipv4
ntpd
inetd
fingerd
sshd ipv4
leafnode nntp


!FIND A WAY TO GET RWHO/RUPTIME.... not in OpenBSD packages/ports


==== install vim =

	pkg_add vim

choose one...?



==== install most (pager) =

this allows coloured man pages




==== lid suspend =

as installed OpenBSD will suspend if the laptop lid is closed. 

To prevent this edit /etc/sysctl.conf

	machdep.lidaction=0

*** update.... this only works for supressing the suspend AFTER
the system is running. Doesn't prevent it suspending if the lid
is closed DURING boot!

Leave the lid up but add something to turn off the console display
(work in progress)




==== shell environment =

OpenBSD uses korn shell (ksh)

add to .profile

===== ftpd =

To make the pre-installed ftpd use only ipv4

edit /etc/rc.conf.local
 
	ftpd_flags=-4


To start the pre-installed ftpd


	rcctl set ftpd status on
	rcctl start ftpd





===== ntpd ==

enable pre-installed ntpd

	rcctl set ntpd status on
	rcctl start ntpd

to check ntp status don't use ntpq!

use 

	ntpctl -s all 




===== inetd (to get fingerd& nntp to work) =


copy example inetd.conf from /etc/examples/inetd.conf
to /etc/inetd.conf

edit inetd.conf to allow finger (add -lsm to get right behaviour)
don't uncomment the tcp6 version


finger stream  tcp nowait  _fingerd /usr/libexec/fingerd   fingerd -lsm


comment out the daytime and comsat lines to prevent them listening.


start inetd

	rcctl set inetd status on
	rcctl start inetd





===== sshd only ipv4 =

edit /etc/ssh/sshd_config

AddressFamily inet

restart

	rcctl stop sshd
	rcctl start sshd





====== install leafnode ==

pkg_add leafnode


edit /etc/leafnode/config

	expire = 20

	server = news.eternal-september.org
 	username = xxxxx
	password = xxxxx
	initialfetch = 100


add to /etc/inetd.conf

	nntp stream  tcp  nowait  _news   /usr/local/sbin/leafnode

restart inetd

	rcctl restart inetd

make an /etc/crontab file to trigger fetchnews regularly


	30 * * * * _news /usr/local/bin/fetchnews
