OpenVPN Inline Certs

Kategorie:OpenVPN To get an OpenVPN-Configuration in one file you can inline all referred files like this:

$ nawk '
/^(tls-auth|ca|cert|key)/ {
  type=$1;
  file=$2;
  # for tls-auth we need the key-direction
  if(type=="tls-auth")print "key-direction",$3;
  print "<"type">";
  while(getline tlsauth<file)
    print tlsauth;
  close(file);
  print "</"type">";
  next;
}
{
  # All other lines are printed as they are
  print;
}' connection.ovpn

And inline to files:

$ nawk '             
/^<(tls-auth|ca|dh|cert|key)>/ {
  type=$1;
  gsub(/[<>]/,"",type);
  file=type".pem";
  print type,file;
  print ""> file;
  while(getline) {
    if($0 == "</"type">"){
      fflush(file);
      close(file);
      break;
    } 
    print $0>>file;} 
  next;
}
{
  # All other lines are printed as they are
  print $0;
}' connection.ovpn > connection_.ovpn
