Query and Change
Ethernet Ports
ethtool
is a Linux utility that allows you to query or change the settings for Port 0 (
eth0
) and Port
1 (
eth1
). For example, to view current settings for Port 0 issue the following command:
ethtool eth0
Here is an example of one way to set the speed on Port 0 to 1000Base-T:
ethtool -s eth0 speed 1000 duplex full autoneg off
The command above will immediately change the port speed to 1000Base-T, but it will revert to its
factory (10/100/1000Base-T) at a system reset. If you want to retain the setting after a system reset,
then you need to edit the
rc.M
configuration file. Follow this sequence:
1. Edit
/etc/rc.d/rc.M
using one of the editors on the previous page.
Insert the desired
ethtool
line (see example above) after the Gatekeeper Daemon is started and
before the Precision Time Protocol is started. Exit and save the
rc.M
file.
2. Now you need to copy the
rc.M
file into a location that will ensure your changes persist
through a system reset. Copy
/etc/rc.d/rc.M
to
/boot/etc/rc.d
as shown:
cp /etc/rc.d/rc.M /boot/etc/rc.d
For more details on
ethtool
and how to use it type:
man ethtool
Redirect Syslog Files
to Remote Host
You can redirect syslog files to a remote host (syslog server) by adding the standard Linux redirect
commands to the Meridian II’s
syslog.conf
file. Follow this sequence:
1. Edit
/etc/syslog.conf
using one of the editors on the previous page. Insert this line:
*.* @remote_host
Substitute the actual name or IP address of your remote syslog server for “remote_host”. The
most common log file to be directed to the Syslog Server is the
messages.log
file which contains
authenticated user login activity. If you would like to only redirect this log info to the remote
host, insert this line instead of the one above:
messages.log @remote_host
Exit and save the
syslog.conf
file.
2. Now you need to copy the
syslog.conf
file into a location that will ensure your changes persist
through a system reset. Copy
/etc/syslog.conf
to
/boot/etc/syslog.conf
as shown:
cp /etc/syslog.conf /boot/etc/syslog.conf
