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:
