Good night, I have my dedicated Linux server and my ubuntu 14.04, I compiled my server and everything is fine, but I can not get out of PUTTY! If I close it the server goes offline. The CTRL + A + D command was minimizing until two days ago, at the moment it only generates A ^. When I open the vps without connecting the server by ./tfs I can minimize using the eating. After opening do not mince at all! And if I close it drops everything.
