I do not often use X11 - but when I do I prefer to enable X11forwarding, and when finished - turn it off. This is preferable, imho, to having "clear" X11 processing when local - and otherwise impossible when working remote. Working with openssh-7.5p2 I cannot figure out what (extra) I need to do with sshd_config to get it working. I know that there is a security-fix starting with

Hi, I am having some trouble with the ClientAliveInterval server setting. My (C++) application fails to start an SSH channel to an OpensSSH server within this time-out period if it doesn't reply correctly to this 'keep-alive' no-op that is sent by the server. How is this no-op handled? I am using the libssh client library, and I could find no references on how to handle this.

Hello, In response to the timing analysis attacks presented by Dawn Song et. al. in her paper http://paris.cs.berkeley.edu/~dawnsong/ssh-timing.html we at Silicon Defense developed a patch for openssh to avoid such measures. Timing Analysis Evasion changes were developed by C. Jason Coit and Roel Jonkman of Silicon Defense. These changes cause SSH to send packets unless request not to,
