19990830: XCD, LDM & Firewalls

Bryan,

Since I didn't see a response to this on the email list, I decided that
it was probably a good idea to respond personally.

>Hopefully this is close to being "on-topic" for McIDAS users, particularly

>10/31/99), and Alden is recommending an LDM/Internet Data Distribution (IDD)
>solution. This has brought up some security issues here.

We have several sites that do this.

>If so, we (JSC) would be interested in chatting with you.

There are typically two ways of doing this:

o have access through port 388 enabled by your network administrator

o have a machine that "sits" on both sides of the firewall

>Thanks,

I am sure that you are probably looking for more information.  If so,
please send your inquiry to address@hidden, and we will farm
it out to the appropriate person.

By the way, I seem to remember trying to convince you (and or Doris)
a couple of years ago that using an LDM for data transfers to/from
sites like Canaveral.
