Ubuntu Install on Sun Fire X4100 network issues
Hi
I have two Sun Fire X4100 machines with Ubuntu 12.04 installed on them.
I am able to configure the Net Mgt port with an IP address and access the ILOM from the browser. I can also boot the Ubuntu installed and redirect the output.
The issue i have is that when i configure the network interface(NET0) from Ubuntu and connect an ethernet cable to it i am unable to reach it via ping or ssh. I am also unable to ping out from it. I can confirm that all the network parameters(IP address,Netmask,gateway) are set correctly. And the NET0 interface is connected to the same switch the Net Mgt is connected to. I can ssh and ping the Net Mgt but not the NET0 interface.
I will really appreciate your help. Thanks

ping(8) System Manager's Manual ping(8)
Name
ping - send ICMP ECHO_REQUEST packets to network hosts
Syntax
/etc/ping [ options ] host [ datasize [ npackets ]]
Description
The DARPA Internet is a large and complex network of hardware connected together by gateways. The command utilizes the ICMP protocol's
mandatory ECHO_REQUEST datagram to elicit an ICMP ECHO_RESPONSE from a host or gateway. ECHO_REQUEST datagrams (pings) have an IP and ICMP
header, followed by a struct timeval, and then an arbitrary number of pad bytes used to fill out the packet. The length of the default
datagram 64 bytes, but this may be changed using the command-line option.
Typing ``ping host'' without any options will either report ``host is alive'' or ``no answer from host''. To get more statistics use the
-l option or one of the other options.
When using for fault isolation, it should first be run on the local host to verify that the local network interface is up and running.
Then, hosts and gateways further and further away should be pinged. The command with options sends one datagram per second and prints one
line of output for every ECHO_RESPONSE returned. No output is produced if there is no response. If an optional npackets is given, only
that number of requests is sent. Round-trip times and packet loss statistics are computed. When all responses have been received or the
program times out with npackets specified, or if the program is terminated with a SIGINT, a brief summary is displayed.
Options
-d Turns on SO_DEBUG flag on the socket.
-l Gives more statistics than if is used without options. Long output.
-r Bypasses the normal routing tables and sends directly to a host on an attached network. If the host is not on a directly-attached
network, an error is returned. This option can be used to ping a local host through an interface that has no route through it. For
example, after the interface was dropped by
-v Lists ICMP packets other than ECHO RESPONSE that are received. Verbose output.
Restrictions
This program is intended for use in network testing, measurement, and management. It should be used primarily for manual fault isolation.
Because of the load it could impose on the network, it is unwise to use during normal operations or from automated scripts.
