openssh unix dev - Aug 2010 - [Feature Request] Allow options in Host block to override global options in ssh

Hi everyone,

For ssh(1) to override global options with the options in "Host"
block, the
attached diff (w.r.t. the openssh code in FreeBSD 8.1-R) contains the code to
do so while parsing ssh configuration file.

This is useful for case like following where {d,proj,p,n}cvs.FreeBSD.org is an
alias to ncvs.FreeBSD.org hostname, thus connecting to
{d,proj,p,n}cvs.FreeBSD.org should utilize the existing connection.

#v+
ControlMaster auto
ControlPath /tmp/%r@%h:%p

Host dcvs
Hostname dcvs.FreeBSD.org
ControlPath /home/abbe/.ssh/cvs.cpath

Host projcvs
Hostname projcvs.FreeBSD.org
ControlPath /home/abbe/.ssh/cvs.cpath

Host pcvs
Hostname pcvs.FreeBSD.org
ControlPath /home/abbe/.ssh/cvs.cpath

Host ncvs
Hostname ncvs.FreeBSD.org
ControlPath /home/abbe/.ssh/cvs.cpath
#v-

Thanks

This isn't necessary, just put the global options in a "Host *"
section
at the end of the file.
