Robert,

re: reason McIDAS data is being written in a different location from GEMPAK

OK, makes sense.

No worries.

OK.

OK.

>My ldmd.log stuff is going to /var/log/messages instead of where it's

The entry for RH 8 is the same for other OSes:

#
# LDM messages on local0
#
local0.debug                            /local/ldm/logs/ldmd.log

I logged on and made the change to your /etc/syslog.conf file, sent
a HUP to syslogd, and now LDM things are being logged to ~ldm/logs/ldmd.log.

Just so you know, I took this opportunity to once again time the build
of McIDAS-X/-XCD.  This time, however, I stopped the LDM and made sure
that the system was idling when I started the build.

The verdict is in: a full McIDAS-X/-XCD build takes 00:07:14 on your
system.  Again for reference, it took 00:05:37 on our dual Athlon 2400+
machine running FreeBSD 4.8.  I think that this goes a long way towards
demonstrating that FreeBSD is pretty darn fast!

>Thanks for all the help,

Glad to help out.

re: syslog.conf entries for LDM logging under RedHat 8.0 Linux

#
# LDM messages on local0

local0.debug                            /local/ldm/logs/ldmd.log

I logged on and made the change to your /etc/syslog.conf file, sent
a HUP to syslogd, and now LDM things are being logged to ~ldm/logs/ldmd.log.

>Thanks I appreciate it.
