OpenBSD initial setup
Some steps that I take when setting up OpenBSD system
First of all, some useful links (yes, I know that the OpenBSD documentaiton is excellent, but sometimes a blogpost is helpful also!).
- https://sohcahtoa.org.uk/openbsd.html nice guide to setting up OpenBSD on laptops. Updated already for the new 7.3 (not major changes, but it stays current).
- https://www.c0ffee.net/blog/openbsd-on-a-laptop more OpenBSD on laptop advice.
- https://www.openbsd.org/faq/faq4.html the official FAQ.
I’ve a guide on setting up peervpn here: https://acronymchile.com/post/2018/07/18/peervpn/ Most of that still applies to OpenBSD. I needed to make one small change In the file platform/io.c (two lines added):
#if defined(__FreeBSD__) #define IO_BSD /* Next two lines added... */ #elif defined(__OpenBSD__) #define IO_BSD #elif defined(__APPLE__) #define IO_BSD #elif defined(WIN32) #define IO_WINDOWS #ifdef WINVER #if WINVER < 0x0501 #undef WINVER #endif
Based on that, things compile just fine.
In configuration, the device must be a tapfile (e.g. tap1). Otherwise, nothing special required.
To enable the service, you need a file in /etc/rc.d such as the following (depends on specific paths, of course)
#!/bin/ksh daemon="/usr/local/bin/peervpn /etc/peervpn/peervpn_joy_configfile.conf" . /etc/rc.d/rc.subr rc_cmd $1
Can then start/stop/enable the service with commands like
doas rcctl start peervpn doas rcctl stop peervpn doas rcctl enable peervpn
Dotfiles and Fossil
I’ve started keeping dotfiles in a fossil repository (just been giving fossil a go). Of course, because this is the only fossil repository, I couldn’t remember quickly how to clone it.
fossil clone ssh://user@hostname//path_info/FossilRepos/mc_dotfiles_rep.fossil \ ~/FossilRepos/mc_dotfiles_rep.fossil mkdir ~/mc_dotfiles && cd ~/mc_dotfiles fossil open ~/FossilRepos/mc_dotfiles_rep.fossil doas pkg_add stow
and so on… (note, host-names and details of paths removed)
XFCE and desktop
I’m lifting heavily from https://www.birkey.co/2022-01-29-openbsd-7-xfce-desktop.html for these instructions
doas pkg_add xfce xfce-extras doas usermod -G operator <user> doas usermod -G wheel <user> echo "exec startxfce4" >> ~/.xsession ## In reality, you probably want ">", but I'm always a bit nervous of ## that and so prefer to play it safe...
