DRAC text console redirection & 1.3.0 C Server Admin released

I've seen some questions in the past regarding out-of-band managment UI via
mozilla on linux so:
The 1.3.0 C Server Administrator release supports (it works i checked)
Mozilla 1.0 on RH Linux.  To get it working you must install the (1.4.0 < X
> 1.4.0_03) j2re from java.sun.com.  Then you've got to link the j2re
libjavaplugin_oji.so (in /usr/java/<version>/plugin/i386/ns610/ on RH8.0) to
a libjavaplugin_oji.so in mozilla's plugin directory.  So, you should be
able to point to the ipaddress of the drac III and login.  More info in the
readme.

Read ya,
Joshua Giles

Hi again, I just thought I'd follow up on my own question with my own
answer, in case anyone else is interested.

Turns out my hunch was right, I needed another open port, and the port in
question is another VNC connection: 5901. I went ahead and openned 5902 and
5903, just in case the DRAC decides to spawn more than just these two VNCs
for some odd reason.

So, if you need to connect to a DRAC, and you want to do it via a SSH
tunnel, or allow connections through a firewall, just forward/open these
ports: 443, 5900, and 5901.
