Managing Icons and Logos
Icons and logos specified in the INI files must be placed in the file server
/wnos/bitmap
subdirectory. Icons are specified in the
Icon
clause of the connection statement and logos
are specified in the
FormURL
statement. Supported image file types include .ico (icon),
.bmp (bitmap), .jpg (JPEG), and .gif(GIF). Color depth for logos can be up to 256 colors.
Color depth for icons can be 16 colors. It is recommended that .jpg format not be used for
desktop icons.
Use the following guidelines:
•
Typical desktop icons are 64 x 48 pixels.
•
Typical sign-on logos are 100 x 61 pixels, with transparent background.
•
Maximum size for sign-on logos is 352 x 80 pixels (if smaller than this, it will be
positioned in the upper-left corner).
Understanding and Using System Lockdown Operations
Lockdown status for a thin client is set or removed using the
LockDown
clause of the
Privilege
statement in the INI files. Lockdown establishes the default privilege level
following thin client boot and before any privilege statement is read from an INI file.
Access to many facilities is affected by the privilege level.
•
Non-Lockdown Operation
- For normal operation, Low-privileged and Non-privileged
users may access the
Network Setup
dialog box by temporarily disconnecting the
Ethernet cable from the thin client and rebooting to Stand-alone user mode. The
Network Setup
dialog box can also be accessed after resetting the thin client to
factory defaults (by a G-key reset to factory default or using the
Reset the system
setting to factory defaults
check box in the Sign-off/Shutdown window of any user
with sufficient privilege to the Sign-off/Shutdown window.
•
Lockdown Operation
- In most cases, access to the resources available when the
system is not locked down is desirable; however, network environments requiring
maximum security should not permit uncontrolled changes to thin client network
access. Most facilities would include a
Privilege
with
LockDown
statement in the
wnos.ini file and might override the privilege in a {username}.ini file without modifying
the lockdown privilege. Thus, an administrator could log into any unit and have
sufficient privilege to modify the configuration of that unit without altering the default
privilege at the next reboot.
Caution
If the unit is configured for Dial-up access, there must be an RAS server
answering the configured telephone number. Otherwise, the unit will require
factory attention to recover it.
