7.2 Access Security
There are several ways of restricting logging in and access to X3200 to autho-
rized users only.
7.2.1 Logging In
Password Logging in to X3200 can be done in several ways as described in chapter 4,
page 81 , but is always protected by a password. Every unsuccessful attempt to
log in is logged with the source of the attempt by a syslog message and creates
a corresponding SNMP trap. Pauses are inserted after several unsuccessful at-
tempts to make it difficult for automatic attempts to find the password.
Until you have changed the default password for the user name
admin
, a warn-
ing is always given after logging in.
Auto logout To make unauthorized access difficult, the connection to X3200 is disconnected
if no keyboard entry is made for a period of 15 minutes. You can change the
time with the command
t <time in seconds>
(see chapter 11.1, page 350 ).
Caution!
All BinTec routers are shipped with the same user names and passwords. As
long as the password remains unchanged, they are not protected against unau-
thorized use. How to change the passwords is described in "Changing the pass-
word", page 95 .

Ethernet connection.
If you carry out a software update (see chapter 8.3, page 322 ), you should
deactivate auto logout as follows: Enter
t 0
in the SNMP shell.
