'ssh -f' option, interoperability with ssh v2.3.0

[Marko Asplund]

i'm trying to use the ssh command's -f option with OpenSSH v2.1.1p4 on
linux (RedHat v6.2). this option doesn't seem to be working properly on my
system - the specified is run succesfully but it isn't put to the
background. is this a known problem?

also, OpenSSH doesn't seem to interoperate with SSH Communications
Security's ssh v2.3.0 (apparently because of different opinions about HMAC
sizes). this can be fixed in the (ssh v2.3.0) configuration files by
specifying:

	MACs		hmac-md5

but is there any work being done for fixing this this problem in OpenSSH's
part?

best regards,
