Return to sshconnect.h CVS log

Up to [local] / src / usr.bin / ssh

Deprecate UsePrivilegedPort now that support for running ssh(1)
setuid has been removed, remove supporting code and clean up
references to it in the man pages

We have not shipped ssh(1) the setuid bit since 2002.  If ayone
really needs to make connections from a low port number this can
be implemented via a small setuid ProxyCommand.
