Ka Kit,

The reason it failed is because you were not in the LDMHOME dir, you need
to more careful about the commands that I send to you. I said to:

% bin/rpc.ldmd -vl - etc/ldmd.conf

not

% rpc.ldmd -vl - etc/ldmd.conf 

It makes a big difference

The reason the gempak data was not being written was dir permissions were
not correct for the user ldm for example:

halo{ldm}% cd storm
halo{ldm}% ls watches
halo{ldm}% ll
total 8
drwxr-xr-x   2 gempak   data         512 Feb  1 16:21 ffg
drwxr-xr-x   2 gempak   data         512 Feb  1 16:16 sels
drwxr-xr-x   6 gempak   data         512 Feb  1 16:20 tropic
drwxr-xr-x   2 gempak   data         512 Feb  1 16:17 watches

The ldm did not have write permission for these dirs


halo{ldm}% ll
total 8
drwxrwxr-x   2 gempak   data         512 Feb  1 16:21 ffg
drwxrwxr-x   2 gempak   data         512 Feb  1 16:16 sels
drwxrwxr-x   6 gempak   data         512 Feb  1 16:20 tropic
drwxrwxr-x   2 gempak   data         512 Feb  1 16:17 watches
