A: Troubleshooting
No connection can be established to the Spider
Check cabling. Are both USB cables or all of the USB and PS/2 cables plugged in? Are both Pwr
LEDs lit? Is the Ethernet cable plugged in, and the Link light lit? Is there Activity?
Have a look on your network. Verify your network configuration (IP address, router). Send a ping
request to the Spider to find out whether the Spider is reachable via the network. Establish a direct
connection between the Spider and the client. If you use a firewall then check the appropriate port
for accepting connections. The TCP ports 80 (for HTTP) and 443 (for both HTTPS and RFB) have
to be open (the server providing the firewall has to accept incoming TCP connections on these
ports). You may restrict these connections to the IP addresses used by the Spider and your client.
Login on the Spider fails.
Verify both your user login and your password. By default, the user sysadmin has the password
PASS. Ensure the web browser is configured to accept cookies.
The Remote Console window of the Spider does not open.
A firewall may prevent access to the Remote Console (TCP port 443). If there is a proxy server
between the Spider and your host, then you may not be able to transfer the video data using RFB.
Check the settings of the Spider and choose a different server port used for RFB transfer. A Java
Runtime Environment may not be installed, or may be disabled.
The video quality is bad or the picture is grainy.
Enter the Remote Console and click the Auto Adjust button to adjust the Spider’s video input
parameters to the correct values.
Special key combinations (e.g., ALT+F2, ALT+F3) are intercepted by the client system and
not transmitted to the remote computer.
You have to define a Button Key. This can be done in the Remote Console settings. Alternatively,
use the soft keyboard feature.
The Spider web pages are not displayed correctly.
Check your browser’s cache settings. Ensure the cache settings are not set to “do not check for
newer pages." Otherwise the web pages may be loaded from your browser cache and not from the
Spider.
Every time I open a dialog box with some buttons, the mouse pointers are not synchronous
anymore.
Disable the setting Automatically move mouse pointer to the default button of dialog boxes
in the mouse settings of your operating system.
The Remote Console does not open with Opera in Linux.
Some versions of Opera do not grant enough permission if the signature of the applet cannot be
verified. To solve the problem, add the lines grantcodeBase "nn.pp.rc.RemoteConsoleApplet"
