HTTPD

OpenBSD - HTTPD CGI

OpenBSD, HTTPD, CGI-BIN

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.

OpenBSD - Minio

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
