Section 12.8 Initial Checkout and Troubleshooting
before
you open the RUDICS
account.
The network configuration and administrative policy at your facility may well dictate that
you receive
a
dministrative approval to make these changes. The actual changes may
have to be done by the Network Administrator. Plan accordingly. It is somewhat ironic
that many times one can get data from the middle of the ocean to the edge of your
building easier than getting that data from the edge of your building to your desk.
12.3.1.2 Public RUDICS IP Port
Select the RUDICS TCP/IP port you will be using. Unless you have an unusually
compelling reason, it is recommended that you use the default Iridium RUDICS port:
6565.
If there is confusion or doubt about what the IP port will be, it is recommended that you
have the Network Administrator reconfigure the network per Section 12.5
CONFIGURATION: Network, Firewall, and Operating System and you test it per
Section 12.8 Initial Checkout and Troubleshooting before you open the RUDICS
account.
12.3.1.3 Glider Authentication
Gliders connecting to a Dock Server via Iridium RUDICS
may optionally
be required to
authenticate before being allowed access to the Dock Server. Unless there are
overwhelming reasons to require Glider Authentication, it is recommended to
NOT
use
this capability.
It is difficult enough to communicate with an at sea Glider without the additional barrier
of a login sequence. It raises the probability that an at sea Glider will be
incommunicado due to misconfiguration, software error, corrupt file, lost password, etc.
If one elects to require Glider authentication, it applies to ALL gliders making an Iridium
RUDICS connection.
If one elects to require Glider authentication,:
(i) All gliders may share the same username/password, or
(ii) Each glider may have a unique individual username/password
The Dock Server Application does NOT do the authentication itself. It utilizes the linux
PAM (
Pluggable Authentication Module)
to require the underlying operating system to
perform the authentication. As shipped, the Dock Server utilizes a local
username/password (
/etc/passwd with Shadow Passwords
) for the authentication. This
