User Manual

Chapter 3. Using the System
3.5.10. SSH
By default, users can use SSH to log in (or SCP and SFTP to transfer files) as user root with
password buffy. The password can be changed on Access Server by using command passwd
or with the setup application.
3.5.11. Telnet
If you enable telnet, users can log in over telnet as user root with password buffy. The pass-
word can be changed on Access Server using the command passwd or with the setup applica-
tion.
Note: Do not enable telnet because it is insecure. Use SSH instead.
3.5.12. NTP
The ntpd service uses the standard Network Time Protocol (NTP) to keep Access Server system
time automatically in sync using a random selection of eight public stratum 2 (NTP secondary)
time servers. The service is also configured to answer NTP requests from other devices.
The NTP server configuration can be altered by editing its configuration file /etc/ntpd.conf.
3.6. Utilities
Access Server is basically a small Linux system. Whether logged in from the management con-
sole or with SSH, your shell session starts as the root user in the root directory. After that, you
have the option to use most of the standard Linux utilities, briefly listed and described in Table
3-3. Most of the commands have a small built-in usage help that can be seen by executing the
command with the -h or --help parameter.
