I logged onto rainbow as 'mcidas' verified that 'mcidas'
can see imagery in the RTIMAGES dataset when looking locally:

After verifying this, I looked to make sure that the remote ADDE
access had been setup; it has been:
rainbow:[64]% uname -a
Linux rainbow.al.noaa.gov 2.6.18-128.4.1.el5 #1 SMP Thu Jul 23 19:59:19 EDT
2009 x86_64 x86_64 x86_64 GNU/Linux
rainbow:[65]% ps -eaf | grep xine

rainbow:[66]% ls /etc/xinetd.d
chargen-dgram discard-dgram ekrb5-telnet ktalk tcpmux-server
chargen-stream discard-stream gssftp mccompress tftp
cvs echo-dgram klogin mcidas time-dgram
daytime-dgram echo-stream krb5-telnet mcserv time-stream
daytime-stream eklogin kshell rsync
rainbow:[67]% cat /etc/xinetd.d/mcidas
#mcidas (port 112)
service mcidas
{
flags = REUSE
socket_type = stream
protocol = tcp
wait = no
user = mcadde
port = 112
server = /home/mcidas/linux/bin/mcservsh
server_args = -H /home/mcidas
log_on_success += USERID HOST
log_on_failure += USERID HOST
}
Seeing that the remote ADDE access is configured to be able to use
uncompressed (port 500), 'compress' compressed transfers (port 503) and
'gzip' compressed transfers (port 112), I then checked your MCCOMPRESS
environment variable setting:
rainbow:[68]% env | grep ^MCC
MCCOMPRESS=TRUE
MCCOMPRESS=TRUE specifies that the ADDE transfers should use
port 503. Since it also specifies that the compression
should be done using 'compress', I checked to see if 'compress'
is available on rainbow; it is _not_.
For recent installations of McIDAS, the preferred compression is 'gzip',
and McIDAS comes bundled with gzip/gunzip, so it does not have to
be installed in the OS.
I verified that by setting the MCCOMPRESS environment variable
to GZIP that I could access the various datasets that are
configured:
rainbow:[72]% setenv MCCOMPRESS GZIP
...

...
So, all that is really needed is for 'mcidas' and any other user
accessing the data via the remote ADDE server to change their
environment to use 'gzip' compression. Again, this is done
by having those users setup MCCOMPRESS to 'GZIP' in their
enviroment. I made the needed change in 'mcidas' .cshrc
file; it tested fine.
While I was at it, I updated some of your client routing table

Last comment:
- I see that you are running an old version of McIDAS, v2005:
lrwxrwxrwx 1 mcidas unidata 9 May 7 13:55 linux -> linux2005
It would probably be a good idea to upgrade to a current version
of McIDAS. The current release is now v2009.
Cheers,
Tom
