Hi Alan,

I got a chance to logon to cyclone (via ssh, so it works nicely) and
found that I couldn't update the /var/data/mcidas directory with
a good copy of SYSKEY.TAB or ROUTE.SYS.  The reason that I was unable
to do this is the directory is owned by 'root', and the write permissions
have not been set for 'mcidas' (or others) to be able to update it:

cyclone% ls -alt /var/data
total 8
drwxrwxr-x  36 root     sys         1024 Apr  3 15:45 ..
drwxrwxr-x   2 root     other        512 Apr  1 14:10 mcidas
drwxrwxr-x   4 root     other        512 Mar 18 15:36 .
drwxrwxr-x   2 root     other        512 Mar 18 15:36 xcd

So, you or someone else with 'root' access on cyclone should:

o change the ownership of /var/data/mcidas and /var/data/xcd to 'mcidas'
  (make sure you change the group to that of 'mcidas' also!)

o delete the copy of SYSKEY.TAB in /var/data/mcidas

o as 'mcidas':

  - copy ~mcidas/data/SYSKEY.TAB to /var/data/mcidas
  - copy ~mcidas/workdata/ROUTE.SYS to /var/data/mcidas

That should get rid of the errors you/the student were seeing with McIDAS
startup.
