Restart SSH Remotely?

[Randall Gellens <randy@pensive.org>]

This is probably one of those "Duh!" questions, but here goes: I've 
installed OpenSSH 3.3, and now want to stop the old sshd and start 
the new one.  I'm not physically at the machine, though.  Since I'm 
connected through ssh, if I kill the current sshd, will the current 
sshd child processes also be killed?  (If so, I won't be able to run 
the new sshd!)  Or will be connection still be OK?

Also, I have this other question:

The updated sshd_config file included with OpenSSH 3.3 has 
"#UsePrivilegeSeparation yes", which to me means that 
UsePrivilegeSeparation is on by default.  So there isn't any point in 
setting it in the sshd.confif file, is there?

Please cc me on any replies.  Thanks!
