HTTPD

Let’s have a look a the old and simple “cgi-bin” stuff on OpenBSD. The Webserver is written by the OpenBSD Guys, and it runs in a chrooted environment.

switch to cgi-bin dir

cd /var/www/cgi-bin/

ip.cgi

create the file under /var/www/cgi-bin called ‘ip.cgi’

cat << 'EOG' > ip.cgi
#!/bin/sh
cat << EOF
Content-type: text/html

<html><head>
<title>IP: $REMOTE_ADDR</title>
</head><body>
<p>Your IP address is: $REMOTE_ADDR</p>
</body></html>
EOF
EOG

Set Owner & Permission

chmod 500 ip.cgi
chown www ip.cgi

as we have the command “cat” in the Script, we need to have this binary in the chrooted HTTP of OpenBSD as well.

Requirements

Fresh VM, running OpenBSD 7.2, fully patched
Public IP, all Ports allowed
FQDN pointing to your IP

run all the commands as root (or with ‘doas’ prepending …)

add Package

as usual with OpenBSD

pkg_add minio

Extend File Limits

we need some more current open files …

cat << EOF >> /etc/login.conf

# Minio, added $(date)
EOF

cat << 'EOF' >> /etc/login.conf
minio:\
  :openfiles-cur=4096:\
  :openfiles-max=8192:\
  :tc=daemon:
EOF

# Rebuild capdb
cap_mkdb /etc/login.conf

don’t forget go restart the box

Intro

Wanna run your own Nextcloud Server on OpenBSD … ? Give a Try ! It’s quite trivial as you can see. Just fireup an empty machine, assign an Hostname / DNS Record, and follow the Examples below. This Setup is done on the current Version, 6.9. Have Fun !

Packages

install some packages. i use sqlite as db because i don’t expect a lot of users/traffic/files.
