2.16 passwd
Changes either user or link password
Syntax
passwd [-n newname] [user]
passwd -r hostname
Description
Use the passwd command to change a user name, a connection password, or the password shared with a
RADIUS server. Only one user name, root, is pre-defined. You can define one local link password for the
local router, up to five passwords for remote connections, one password for each of the Router’s
modems, and one password for each RADIUS server in use. The password stays the same for each login
until the administrator changes it. No aging of passwords is performed.
When changing a password the user is prompted for the old and then the new. Both are required. The
new password must be typed the same way twice to ensure accuracy. If no previous password exists, the
new password must still be typed the same way twice.
New passwords must be at least five characters long if they combine capitalized and un-capitalized
letters, or at least six characters long if in all in the same case. Although longer passwords are accepted,
limit the maximum number of significant characters in a password to eight, because password algorithms
do not work with more than 8 characters. The passwd file contains user and password information.
