How to change the root password

The S100 is shipped with a default root password of symmetricom. For security reasons, it is a very good idea to change that password immediately.

To change the root password, use the following steps:

1.Use HyperTerminal or Tera Term (included on the enclosed CD) on the serial port, or SecureShell using PuTTY (included on the enclosed CD). Log in as User root with Password symmetricom.

2.Type the command passwd, all lower-case (UNIX commands are always case-sensitive).

3.You will be prompted to type your new password, and then to type it again to confirm. This is what you will see:

[root@syncserv1 /root]# passwd New UNIX password:

Retype new UNIX password:

passwd: all authentication tokens updated successfully [root@syncserv1 /root]#

Note: The password command “prefers” passwords containing a random variety of letters and numbers, and no common words. So if you use a recognizable word as the new pass- word, you may get an error message that looks like this:

[root@syncserv1 /root]# passwd New UNIX password:

BAD PASSWORD: it is based on a dictionary word

Retype new UNIX password:
