feature password protection. Starting the GUI without password is accomplished by a
few steps to be entered via the Linux console.
If you disable the vnc password for the R&S OSP, the network access control is in your
own responsibitity.
Once the vnc password is disabled, the instrument remains in this state, until the
usage of a vnc password is explicitely enabled again.
Disabling the password:
1. Switch on the R&S OSP. The actual IP address must be known.
2. Start an application program (like PuTTY or similar) and connect your PC to the
R&S OSP. When asked for the login, use the login name root and the password
root.
3. Type in the following commands:
cp /etc/inetd.conf /etc/inetd.conf.ori
sed -i 's/vnc.*/vnc stream tcp nowait root \/usr\/bin\/x11vnc x11vnc -display :0 -
inetd -q -speeds dsl/' /etc/inetd.conf
reboot
This is shown in the following dialog:
With the password disabled, the R&S OSP GUI is started without any VNC
authentication.
Enabling the password again:
1. Switch on the R&S OSP. The actual IP address must be known.
2. Start an application program (like PuTTY or similar) and connect your PC to the
R&S OSP. When asked for the login, use the login name root and the password
root.
