Which displays the contents of the /etc/resolv.conf le containing the domain name you entered previ-
ously using netconfig, and the nameserver IP address(es) to use for that domain.
Check Network Operation
With your Sonoma network parameters properly congured, you are ready to test the setup using
ping from a server or workstation that is able to access the network connected to the Sonoma. Al-
ternatively, you could ping one of your servers or workstations from the Sonoma prompt to test the
setup.
Once you have successfully established network communications with the Sonoma, you may perform
all maintenance and monitoring activities via telnet and ftp. The Sonoma provides both client and
server operation using telnet. For security reasons, only client operation is supported using ftp.
You may also monitor the Sonoma via the HTTPS interface (see Chapter 7 - HTTPS).
Security conscious users will want to use ssh, the secure shell replacement for telnet, as the login
means. The companion utility, scp provides a secure replacement for ftp as a means of transferring
les to and from the Sonoma. Both of these protocols are supported in the Sonoma via the OpenSSH
implementations for Linux. Refer to Chapter 5 - Security, OpenSSH for more information about the
secure shell protocol.
Using Telnet
When establishing a telnet connection with your Sonoma, logging in directly as root is not permit-
ted. This is a security measure that makes it slightly more difcult to gain access by simply trying
passwords, since it is also necessary to know the name of a user. When you initiate a telnet session
with the Sonoma, this banner will be displayed:
********************************************************************************
* Welcome to Sonoma_D12 CDMA telnet console on: host.your.domain
********************************************************************************
host login:
Here you may log in as “ntpuser” with password “Praecis”. When logged in as “ntpuser”, you may
check status information and view log les but you will not be able to modify any system settings or
view secure les. After correctly entering the password at this prompt,
Password:
the sign on message is shown. It identies the host system as Sonoma CDMA and shows the soft-
ware part number, version and build date:
Sonoma_D12 CDMA 6010-0065-000 v 1.00 Sat Jan 19 14:17:44 UTC 2013
Sonoma_D12 CDMA (root@host:~)->
This last line is the standard Sonoma CDMA prompt. After conguring the unit, you should change
the passwords using the Linux passwd command issued from the prompt.
To gain root access, you must now issue the “super user” command at the prompt:
