I use ControlMaster auto (along with ControlPath) in my ssh config and find it very handy. I have noticed an annoying behavior, though: it seems that if there is no existing master connection and ssh creates a new one, the master connection process that is started has its stderr left open. This has manifested itself in two ways so far: (1) When using ssh day-to-day, I may be doing some work and

When I'm running interactive ssh session which is ControlMaster and I run scp or sftp to same host, creating another channel, it seems that ssh is stuffing the packets together exceeding MTU. I've for years ran QoS where I prioritize small packets, as it is clean and easy way to guarantee low latency to pretty much all you care for. Unfortunately ControlMaster packet stuffing breaks this,

Dear Mailing List We are using a ControlMaster with a short ControlPersist to access the bastion host which then gives access to customer hosts. Our Information Security Manager would like to disallow the ControlMaster. His attack scenario is an admin workstation with a compromised root account. An attacker can then use the ControlMaster to trivially get shell access on the bastion host
