how to get
around proxy servers and
firewall when running DS9 or VNC
questions to ask of the computer admins
1) are you running a proxy
server?
a) if
no,
do nothing special; go to question 3
b) if yes, ask question 2
2) is the proxy required?
a) if
no,
do nothing special; go to question 3
b) if
yes, set proxy server in ds9: under Edit menu, select
Preferences>, HTTP
then type proxy host and proxy port in the
pop-up box
also, save
Preferences: under Edit menu, select Preferences>,
Save Preferences
go to question 3
3) are you using a firewall?
a) if
no,
only the proxy setting is needed (and only if answer was "yes" to
question 1); ds9 should work properly
b) if
yes, ask question 4
4) is firewall set to DENY ALL?
a) if
yes,
firewall must be adjusted (both trust-to-untrust and untrust-to-trust)
:
(1) the
following IP addresses for ds9 servers must be allowed access for DS9
to function
128.6.239.124
for
basho.rutgers.edu access
131.142.40.41
131.142.41.9
131.142.41.10 for
chandra-ed.cfa.harvard.edu access
(2)
port 28574 must be open for DS9 server access
(3) the
following IP address must be activated for VNC to function:
128.6.239.124
for
basho.rutgers.edu access
(4)
port 5900 must be open for VNC access
DS9 and VNC should now work properly in all
of the above changes are made
b) if
no, DS9 and VNC should work properly
