#Add other user additions here:

If you want to disable any of the servers, comment out the setenv line for that server. You

can also set other environment variables for the system and for the network servers in the

user setenv area. See the section for each of the servers for a list of user-controlled

environment variables.

Add lines to run in the user additions section at the end of the .startup file.

You can hit the '5' key when slush begins to boot to bypass the .startup file and bring up the

Serial server.

II . Serial Server

The Serial Server provides TTY login to the slush system.

Configurable options with environment variables:

setenv HISTORY

[size]

- Size of history command buffer.

setenv BROADCASTS

[true/false]

- Allow or disallow wall broadcasts. Default

is true.

Note: This variable will not take effect until the server is restarted.

A user can create a home directory (i.e. a directory with the same name as the user's

username) in the root directory. When the user logs in, they will be placed in this directory.

Otherwise, the user is placed in the root directory at login.

The user can also place a .login file in their home directory. Every line in this file will be

executed as they would from a slush command prompt. You can comment out lines by

inserting a '#' at the beginning of a line.

Slush is setup by default to use serial0 at 115200. If you need to change the port, or set the

speed down to 19200, edit Slush.java. Change the SERIAL_PORT and SERIAL_SPEED

and other variables to your needs, and rebuild. For help in the build process, see

Building_Applications.txt.

III. Telenet Server

The Telnet server listens on port 23 (the well-known port for Telnet) for connection requests,

and spawns off sessions to handle each request.

Configurable options with environment variables:

setenv TELNET_ALLOW_ROOT [true/false]

- Allow or disallow root to login to Telnet. Default

is true.

setenv HISTORY [size]

- Size of history command buffer.

setenv TELNET_TIMEOUT [Number of ms]

- Inactivity timeout. 0 is infinite. Default inifinity.

setenv TELNET_WELCOME [file]

- File to display on successful login.

setenv BROADCASTS [true/false]

- Allow or disallow wall broadcasts. Default is

true.
