1/15    Two sys admin questions:
        1) How do I disable EXPN in sendmail 8.8.7?
        2) Is ssh 1.1 client compatible with ssh 2.0 server?
           \_ i think you need to install the old sshd and then tell ssh2d
              to accept ssh connections using sshd rather than ssh2d.  The
              protocols are different and hence are not compatible.
        \_ bang yourself on the head with a ball-peen hammer until you
           get over this stupid idea that you should disable EXPN.  -tom
