some tools for Freifunk Gluon to enhance ssh logins with many infos and some miniscripts and maintainance, for example

alfredcheck  autoupdater-status  clientwifi  fastd-status  geoguess_legacy  hop_penalty  location  meshwifi  MoW       nodename  sshkeys  uplinkif
alt          branch              contact     geoguess      help             lat          lon       MoL       nodeinfo  snping    status   v4up		 wginfo

supersimple example of php for geoguess (because small freifunk router cannot connect to https ... so you have to be tricky)

<?php

function IsValid($mac)
{
  return (preg_match('/([a-fA-F0-9]{2}[:|\-]?){6}$/', $mac) == 1);
}

# validate and append all macs
foreach($_GET as $mac=>$val)
  { if(IsValid($val)) { $full .= "{\\\"macAddress\\\": \\\"$val\\\"}," ; } };
# remove last ","
$full = rtrim($full, ",");
# substr($full,0,-1);

system("wget -qO- \"https://location.services.mozilla.com/v1/geolocate?key=test\" --post-data=\"{ \\\"wifiAccessPoints\\\": [$full],\\\"considerIp\\\": \\\"false\\\"}\" ");
