Which displays the contents of the
/etc/resolv.conf
file 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 RTM3205 network parameters properly configured, you are ready to test the setup using
ping
from a server or workstation that is able to access the network connected to the RTM3205.
Alternatively, you could
ping
one of your servers or workstations from the RTM3205 prompt to test
the setup.
Once you have successfully established network communications with the RTM3205, you may per-
form all maintenance and monitoring activities via
telnet
and
ftp
. The RTM3205 provides both
client and server operation using
telnet
. For security reasons, only client operation is supported
using
ftp
. You may also monitor the RTM3205 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 transfer-
ring files to and from the RTM3205. Both of these protocols are supported in the RTM3205 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 RTM3205, logging in directly as
root
is not per-
mitted. This is a security measure that makes it slightly more difficult 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 RTM3205, this banner will be displayed:
********************************************************************************
* Welcome to RTM3205 GPS telnet console on: host.your.domain
********************************************************************************
host login:
Here you may log in as “sysuser” with password “Praecis”. When logged in as “sysuser”, you may
check status information and view log files but you will not be able to modify any system settings or
view secure files. After correctly entering the password at this prompt,
Password:
the sign on message is shown. It identifies the host system as RTM3205 GPS and shows the software
part number, version and build date:
RTM3205 GPS 6010-0069-000 v 1.00 Sat Jan 19 14:17:44 UTC 2013
RTM3205 GPS (root@RTM3205:~)->
This last line is the standard RTM3205 prompt. After configuring 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:
RTM3205 GPS(root@RTM3205:~)-> su root
