[McIDAS #VSV-153140]: Mcidas xcd

Hi Heather,

Sorry for the slow replies -- we have a User's Committee meeting here in
Unidata today and tomorrow, so my time is pretty well occupied except
at breaks.

OK.  There are a couple of additional settings in /etc/sysctl.conf that I
need to pass along:

#
# Enable DVBS reception
#
net.ipv4.conf.default.rp_filter = 2
#
# DVBS multicast fragment reassembly 
#
net.ipv4.ipfrag_max_dist = 0

You may also want to disable ipv6 (but this does not have anything
to do with being able to read data from the Novra):

net.ipv6.conf.all.disable_ipv6 = 1

OK.

Is there any chance we could login to your machine?  I seem to recall some years
ago that I was allowed to VPN into one NGC system and then SSH to another, but
I do not recall the details.

re:
> As for mcidas.  This is what I get when I give the tl.k command:
> [mcidas@npxcd workdata]$ tl.k
> H           := 17:29:45

> XCDDATA     := /data
> Y           := 2014258
> --END OF LIST

OK.  The McIDAS string MCDATA does exist, and it is setup to what I
would expect ** assuming that the HOME directory of 'mcidas' is
/home/mcidas **.

re:
> [mcidas@npxcd workdata]$ echo $MCDATA
> /home/mcidas/data

This is incorrect for Unidata McIDAS where it would be ~mcidas/workdata
(which would seem to be /home/mcidas/workdata in your case). 

re:
> But my MCDATA is set in my .bashrc to be /home/mcidas/data!

> What did I do wrong?

To answer better, please send me copies of your ~/.bashrc and ~/.bash_profile
files.

I will try to call tomorrow, but our User's Committee meeting goes until
noon MDT and I have a dentist appointment at 14:00 MDT.  If it is at all
possible to login to your system, the troubleshooting would go much faster.

Cheers,

Tom
