A short (one line) script for linux that pings all clients on your network. If using another subnet than 192.168.0 then you have to adjust the numbers.

export i=0;
while [[ $((++i)) -le 254 ]];
do ping -c1 -w1 192.168.0.$i | grep ttl | cut -d " " -f4 | cut -d ":" -f1;
done;

There are a lot of companies around that offer GPS car logging solutions. But if you take a closer look on what they offer then you find out that they are not really flexible when you have non standard needs.

The following describes a work in progress. Basically it works as intended but it still has to prove it’s long time stability. Continue reading »

Building VPN Connections from any Windows client against IPCop running Zerina is actually very straightforward. Doing that from a Ubuntu client is a little bit tricky since ubuntu’s network manager cannot handle Zerina’s .p12 (pkcs) files.

• Install network-manager-openvpn using synaptic
• I know it’s not linux style – but do a reboot know – just to insure that all services are running. I had no success with the next steps without rebooting. Or I’ve been too lazy searching for the services that needed a restart.
• Download the .p12 file from IPCop or ask someone to do it for you.
• Now you have to extract 3 certificate files out of your .p12 file.
  
openssl pkcs12 -nocerts -in (filename).p12 -out userkey.pem
openssl pkcs12 -nokeys -clcerts -in (filename).p12 -out usercert.pem
openssl pkcs12 -nokeys -cacerts -in (filename).p12 -out userca.pem

  Or download that script and call it with pkcs2certs.sh your-username.p12 and it’ll create the required files for you.
• Now place the files into your vpn configuration and make the settings match your zerina configuration (cipher, compression etc.)
