I logged onto snow and noticed something that was odd:

There are a LOT of new entries in /etc/services.  In particular, there
are new services that have the same port number that the ADDE compressed
(port 503) and uncompressed (port 500) want to use.

I took the liberty of commenting out the process in /etc/services that
conflict with the ADDE use:

%cat /etc/sevices
 ...
mcserv          500/tcp      # McIDAS ADDE port
mccompress      503/tcp      # McIDAS ADDE compression port
#isakmp         500/tcp
#isakmp         500/udp
stmf            501/tcp
stmf            501/udp
asa-appl-proto  502/tcp
asa-appl-proto  502/udp
#intrinsa       503/tcp
#intrinsa       503/udp
 ...

I then looked at the entries in /etc/inetd.conf and saw that they were
not quite correct.  To update them, I did the following (as 'root'):

cd ~mcidas
sh ./mcinet7.7.sh uninstall mcadde
sh ./mcinet7.7.sh install mcadde

All this did was first uninstall the ADDE changes to /etc/services and
/etc/inetd.conf; reinstall them; and then send a HUP to inetd.

After doing the above, I can successfully access snow via ADDE (get
information, list and display images; create a display through your
Make your own McIDAS GINI page; etc.)

There is one thing that is different that I should point out.  Perviously,
ADDE access was wrapped by tcpd.  This was why an entry was needed in
/etd/hosts.allow.  Now, there is no tcpd wrapper, and I can't find tcpd
on your system (a 'locate tcpd' doesn't reveal its hiding place).  If
you can locate tcpd (or reinstall it), we should redo the /etc/inetd.conf
entries so that it is used for the ADDE stuff.  I can do this as soon
as you point me to the location of tcpd.

"tcpd" is no longer need on FreeBSD as of 4.0.  The functionality of TCPD
is wrapped into "inetd".   See /etc/hosts.allow if you want to deny access
to IP's.  You would need to put the rule before the:

ALL : ALL : allow

line though...
