Sysmon feature causes ssh connection failure !

I found that Sysmon feature probably tries to open a ssh channel 0 which is not supported by all ssh server , for some network devices , while received open channel 0 request , they will mean to shutdown the ssh connection. This made the ssh connection always fail ! Please ,make this feature optional, instead of mandatory .

Inspect the Sysmon feature and the SSH path that opens channel 0, then reproduce the failure against an affected network device or SSH server. Done means Sysmon can be disabled and the SSH connection succeeds without requesting the unsupported channel.
