ports.
Keyboard strokes are shifted.
Press both Shift keys.
Certificate warning shown while connecting via HTTPS.
It is normal for a warning dialog to be shown when connecting via HTTPS. The SSL
certificate we use is created when the unit is first produced. It does not contain the correct
hostname (subject name) because you can change the hostname as required. Also, it is
not signed by a recognized certificate authority (CA) but is signed by our own signing
authority. For more details, refers to “Appendix A: About Security Certificate Warnings.” on
page 32.
Windows XP doesn't awake from standby mode.
This is possibly a Windows XP problem. Try not to move the mouse while XP goes into
standby mode.
The terminal connection to NewStar Digital KVM via IP for initial configuration
cannot be established.
Check that the Null Modem cable connected to DCE Serial Port on the NewStar Digital
KVM via IP and terminal software is set to the following line parameters:
Connection speed: 115200 bps
No. of bits: 8
Parity: None
Stop bits: 1
Flow Control: None
Connect computer to the NewStar Digital KVM via IP and power this computer on. Power
on the NewStar Digital KVM via IP while pressing the ESC key on the keyboard
connected to it? This will switch the DCE Serial Port 1 to Configuration Login setting even
if it was set to Pass-through or Modem.
Also, Windows HyperTerminal has a bug: if you change baud rates while connected. the
screen is updated but the hardware is still at old baud rate; hang up and reconnect (using
icons at top of screen) to make new settings take effect.
If my network has a firewall, what setting do I use on the IP Extender to open a port
into the network?
You shouldn't change any settings in the NewStar Digital KVM via IP, but you should
open port 22 for both outbound and inbound connections in your firewall.
Port 22 only needs to be opened for inbound connections. You must use SSH tunnel to
connect to machine; tunnel to port 127.0.0.1:5900 for VNC protocol, and 127.0.0.1:80 for
HTTP (web) control.
OR, instead of SSH client, open ports 443 and 15900 (inbound) for HTTPS and encrypted
VNC protocol. Then click always on the "encrypted" link. This is easier because you don't
need to setup SSH tunnels.
