Donna,
Use telnet(1) to verify that each host can contact the LDM port on the
other:
On Earthdata:
telnet curio 388
On Curio:
telnet earthdata 388
(You should use the fully-qualified hostnames for each to reduce DNS
issues). If one of them doesn't work and both LDM-s are running, then
something is blocking the TCP connection.
Regards,
Steve Emmerson
