== 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
