Well, in this line: if(line.find('PING') #If server pings then pongs You are missing a : at the end. So fixed up is should look like: if(line.find('PING'): #If server pings then pongs s.send('PONG '+line[1]+' :'+ot+'n') print('PINGED!') I still have no idea where you are getting the ot variable from, I only see it in the syscmd function (which returns 0)? That should fix it, you got it right on the second if in the while loop though.
