Warn if no server running #7

Open richb-hanover opened 1 year ago

richb-hanover commented 1 year ago

I got the following error message when I ran the client without a server running at the other end.

A simple "No server seems to be running at \" would suffice

?134 release % ./crusader test 192.168.253.128

zsh: abort      ./crusader test 192.168.253.128

I agree that this will be a good improvement.
