+Example: Connecting to remote postgresql
+========================================
+
+(1) On both the local & remote hosts:
+
+adduser -s /bin/false autossh <with blank passwords>
+-------------------------------------------------------------------
+
+(2) On the local client create an SSH key with an empty password:
+
+su -s /bin/sh autossh
+echo 'y' |ssh-keygen -t ed25519 -N ''
+-------------------------------------------------------------------
+
+(3) If using runit for service supervision < /etc/sv/autossh/run >:
+
+-------------------------------------------------------------------
+#!/bin/sh
+exec 2>&1
+su -s /bin/sh autossh -c \
+'autossh -M 0 -o "ServerAliveInterval 60" -o "ServerAliveCountMax 3" -L 1234:localhost:1234 -N -l autossh remote.ip.addr'
+-------------------------------------------------------------------------------------------------------------------------
+ln -s /etc/sv/autossh /etc/service/autossh
+-------------------------------------------------------------------------------
+** if running autossh in a script without using runit add -f to ssh options **|
+-------------------------------------------------------------------------------
+
+(4) Connect with:
+
+psql -h 127.0.0.1 -p 1234 -U username -d database
+-------------------------------------------------------------------------------
+openssh-server: works out of the box | ed25519 keys possible
+dropbear: echo "/bin/false" >> /etc/shells | ecdsa keys possible
+tinyssh: port forwarding not yet implemented | ed25519 keys possible
