[ale] PPP/SSH VPN dies randomly



We are using Bob's VPN setup for SSH/PPP tunnels.  We have uptime of
around 2-5months at a time and is only increasing as he discovers new
ways to overcome PPP and SSH snafu's.  I would recommend looking at
turning off PPP compression and also making sure SSH doesn't quit on a
"~." character pair.  I believe Bob could fix that for you with some
switches on SSH and PPP.  You don't have to accept downtime on your
SSH/PPP VPN tunnel.  We regularly have no glitches at all.  I also know
that Bob has developed as part of his product an autorestart VPN.  We
will be testing that out in the next couple of weeks.  I have had
dropouts on the VPN when a switch is recycled by our ITS without my
knowledge.  With the autorestart function based around SSH passphrase
authentication, I won't have to worry about the VPN anymore.  In fact,
since we started using Fly-by-Day, I haven't had to worry about security
very much at all.  Really has made a difference in my productivity as a
researcher/sysadmin.  Hope this helps,
Dow
