A: Why, yes! We’ve created a special document called “
Information for IT Managers
” which was written specifically
to help keep the blood pressure and stress levels of IT managers within normal tolerance. It can be found in the
APPENDIX B
of this manual or in the support section of our website at www.comrex.com
Q: my IT guy IS CONCErNED AbOuT SECurITy AND WANTS
TO kNOW WhAT SErVICES ArE OPEN ON ThIS bOX.
A: As mentioned, we’re serving an HTML/XML page on the well known server port, 80. Our streaming application is
UDP/RTP on port 9000 (9001 for CrossLock connections). SSH is enabled by default but requires a passkey. You can
disable it completely in the
Security
section of the
System Settings
menu by setting the
Remote Diagnostics
option
to
Not Enabled
. Leaving
Remote Diagnostics
(SSH) enabled will help if Comrex support needs to interface with your
ACCESS.
Q: I NOTICE IN ThE ADVANCED OPTIONS ThAT I CAN ChANgE
my STrEAmINg frOm uDP TO TCP. ShOulD I?
A: Not if you want the best overall performance. ACCESS is optimized in terms of data rate, stability and delay to
use UDP. TCP mode increases overhead and delay, and is included only for environments where UDP is hopelessly
blocked by a firewall. ACCESS decoders do listen to both TCP and UDP ports and choose whichever arrives first. If an
ACCESS gets an incoming TCP connection, it will establish TCP in the other direction automatically. One other note
for use with TCP — most of the information presented on the
Stats
tab is generated by the UDP functionality, so
you won’t see much here using TCP.
