Solaris Networking Commands

How to add a NIC card on Sun:

ifconfig hmeX plumb
ifconfig hmeX inet xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx
ifconfig hmeX up

How to change a hostname on Sun:

Make sure to use notepad or vi to edit files in order to avoid hidden characters.

There are four files that must be modified in order to rename the hostname:

1) /etc/hosts
2) /etc/net/ticlts/hosts
3) /etc/net/ticolts/hosts
4) /etc/nodename
5) /etc/hostname.hmex
6) /etc/net/ticotsord/hosts

Another way to change the hostname is by using sys-unconfig command. This restores the system to an unconfigured
state and should only be used when you are not concerned about preserving the current setup of the system. I suggest
looking at the man pages for further information (man sys-unconfig) or edit the following files above.

Note: rename the directory under /var/crash to match your new hostname.

Sun Solaris Servers Network Configuration Guide (SPARC Platform Only)


To bind an IP address to a Network Interface Card
#ifconfig -a
--- to check the configuration
#ifconfig qfe0 plumb
--- to enable the first Network Interface Card
#ifconfig qfe0 <ip address> netmask <subnet> up
--- to bind IP address, subnet, and enable the configuration

Create a file on /etc directory - hostname.qfe0 with hostname entry
Add entry on /etc/netmasks if IP address is on different subnet
Add entry on /etc/inet/hosts file with IP address and hostname

Example:
#ifconfig -a
hme0: flags=863<UP,BROADCAST,NOTRAILERS,RUNNING,MULTICAST> mtu 1500
inet 202.40.231.2 netmask ffffff00 broadcast 202.40.231.255
ether 8:0:20:9f:51:fe

#ifconfig qfe0 plumb
#ifconfig qfe0 202.40.231.3 netmask 255.255.255.0 up
#ifconfig -a

hme0: flags=863<UP,BROADCAST,NOTRAILERS,RUNNING,MULTICAST> mtu 1500
inet 202.40.231.2 netmask ffffff00 broadcast 202.40.231.255
ether 8:0:20:9f:51:fe
qfe0: flags=863<UP,BROADCAST,NOTRAILERS,RUNNING,MULTICAST> mtu 1500
inet 202.40.231.3 netmask ffffff00 broadcast 202.40.231.255

To change IP Address
#ifconfig qfe0 down
--- to disable the first Network Interface Card

To remove Network Interface Card
#ifconfig qfe0 unplumb
--- to remove the first Network Interface Card

To bind a virtual IP address to Network Interface Card
#ifconfig qfe0:1 plumb
--- in some cases this is not needed if qfe0 has been plumb
#ifconfig qfe0:1 202.40.231.4 netmask 255.255.255.0 up

Create a file on /etc directory - hostname.qfe0:1 with hostname entry
Add entry on /etc/netmasks if IP address is on different subnet
Add entry on /etc/inet/hosts file with IP address and hostname

NOTE:
-If adding a quad

Network Interface Card, the naming convention will be qfe0, qfe1, qfe2, qfe3.
-If adding a single port Network Interface Card, the naming convention will be hme1, hme2, hme3.
-The onboard Network Interface Card is hme0
-If adding a virtual IP address, the naming convention will be hme0:1, hme0:2, up to hme0:3 only for hme0,
or qfe0:1, qfe0:2, up to qfe0:3 only for qfe0, depending on the number of hme and qfe port used.


To hardcode the speed of the Network Interface Card
Example:
You want to hardcode 100Full Duplex for hme0
#ndd -set /dev/hme instance 0
#ndd -set /dev/hme adv_100fdx_cap 1
#ndd -set /dev/hme adv_100hdx_cap 0
#ndd -set /dev/hme adv_10fdx_cap 0
#ndd -set /dev/hme adv_10hdx_cap 0
#ndd -set /dev/hme adv_autoneg_cap 0

Create an input on the file /etc/system so that when your system rebooted it will run the NIC in 100Full Duplex
automatically.
set hme:hme_adv_100fdx_cap=1
set hme:hme_adv_100hdx_cap=0
set hme:hme_adv_10fdx_cap=0
set hme:hme_adv_10hdx_cap=0
set hme:hme_adv_autoneg_cap=0

To check the status
#ndd /dev/hme \?
--- displays all command options for ndd
#ndd /dev/hme link_status
--- displays the hme0 link status

The above configurations should be followed in order.

1 = Capable/Enable
0 = Disable
hme1 = instance 1
hme2 = instance 2
hme3 = instance 3

The system on the other end of network cable should be hardcode to 100Full Duplex also. If the other end is a
switch, check your vendor manuals on how to do it.

To monitor packets traveling in your NIC ports
Example:
You want to monitor your hme0 port of packets coming from IP address 202.40.224.14
#snoop -d hme0 | grep 202.40.224.14

You want to monitor your qfe1 port of packets coming from host server1
#snoop -d qfe1 | grep server1

You want to monitor your hme1 ports of all packets
#snoop -d hme1

To add or remove a static route
Example:
You want to add a static route to network 192.168.16.0 to your default gateway of 10.236.74.1
#route add -net 192.168.16.0 10.236.74.1

then create a script, so that when the system rebooted the route will automatically added
#cd /etc/rc2.d
#vi S168staticroute

Add the following line
route add -net 192.168.16.0 10.236.74.1

You want to add a static route to host 192.168.64.4 to your default gateway of 10.236.74.1
#route add 192.168.64.4 10.236.74.1

then create a script, so that when the system rebooted the route will automatically added
#cd /etc/rc2.d
#vi S168staticroute

Add the following line
route add 192.168.64.4 10.236.74.1

You want to delete the static route to network 192.168.16.0 to your default gateway of 10.236.74.1
#route delete -net 192.168.16.0 10.236.74.1

You want to delete the static route to host 192.168.64.4 to your default gateway of 10.236.74.1
#route delete 192.168.64.4 10.236.74.1

I just want to contribute a little bit.
