HI Andreas, I started my work on stroke utility .
Initially I was having some segfaults but was able to resolve them. I was able to add connections via CLI which was evident from ./stroke statusall . But I was unable to initiate the added connections. I started my work by hard-coding the stroke message to a certain extent later on I will be cleaning up the code. I have attached the Log files and the modified code. Please help me or direct me the hack to initiate the connection. I will go ahead.
