The functionality requires ssh v2 to work at all. Of course, of top of that, your particular ssh v2 implementation needs to support it. In the case of OpenSSH, the support has existed for over two and half years. See revision 1.77 of ssh/servconf.c[0]. > It's not that simple.

Well, if we're talking about OpenSSH, you'd be crazy to be running any version prior to the existence of the privilege separation functionality, which came a good deal of time after the ClientAliveInterval support was added.
