The remote access to the KWh meter depends on a SSH tunnel on the MTA.

File in systemd at: /etc/systemd/system/kwh-tunnel.service:

   [Unit]
   Description=Tunnel to kWh meter.
   After=network.target
   
   [Service]
   ExecStart=/usr/bin/ssh -i /etc/kwh-meter-tunnel -l dirkx -p 222 -T \
        -o ServerAliveInterval=60 -o ExitOnForwardFailure=yes \
        -L 9999:192.168.6.111:80 \
        -L 1161:127.0.0.1:1161 \
        83.163.200.191 -
   RestartSec=30
   Restart=always
   
   [Install]
   WantedBy=multi-user.target

and

   [Unit]
   Description=Local end of SNMP Tunnel to kWh meter.
   After=network.target
   [Service]
   ExecStart=/usr/bin/socat -T15 udp4-recvfrom:2161,bind=127.0.0.1,reuseaddr,fork tcp:127.0.0.1:1161
   RestartSec=30
   Restart=always
   [Install]
   WantedBy=multi-user.target

and this is received by a SSH authorized key line on the space machine:

      no-pty,permitopen="192.168.6.111:80",permitopen="127.0.0.1:1161",command="/usr/local/bin/socat tcp4-listen:1161,reuseaddr,fork UDP:192.168.6.111:161" \
             ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC1...xPGezJYI0wMNlI9XiP kwh tunnel

With localhost:9999 mapped in the CRM for those that need access.

MRTG setup

This should be fixed - i.e. not run as root !!

   [Unit]
   Description=Multi-router Traffic Grapher
   After=syslog.target
   [Service]
   Environment=LANG=C
   ExecStart=/usr/bin/mrtg --daemon 
   Type=forking
   SuccessExitStatus=0 1
   [Install]
   WantedBy=multi-user.target
