Solaris

Hi,

Need help for the network configuration on Solaris 10 5/8.

My NIC's dirver was loaded after Solaris installation and is configured using static ip address for a local network:

172.16.1.12

I have configured set of files as:

/etc/hosts :

172.16.1.12 ls12

/etc/hostname.iprb0:

ls12

/etc/nodename:

ls12

Physical network cable connections checked and all good.

The problem is that I can ping the machine itself but can not ping others on the subnet 172.16.1.0

While another computer with address of 172.16.1.15 has no problem at all. The only difference for those two computers is that the nic on second one was recognized by Solaris during installation time and the network configuration was done during the installation time.

What is the problem for the first one?

thanks

What is the output from an ifconfig -a? have you checked the netmask?

# ifconfig -a

lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1 inet 127.0.0.1 netmask ff000000

iprb0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2 inet 172.16.1.12 netmask ffffff00 broadcast 172.16.1.255 ether 0:1e:90:cd:9a:a4

Do you have the default GW set correctly in /etc/defaultrouter? Might not be the cause, but make sure it is set properly before further troubleshooting. The output from netstat -rn would give an indication as well.

your /etc/netmask and /etc/defaultrouter should be set

whether the interface is recognized during installation or not doesn't mean the interface doesn't work. could be that this interface is not native to sol10 os. as long as the correct drivers are loaded into the kernel, the interface will work as advertised. i'm going with incredible on this one.
what is the output of the following commands:
dladm show-dev
netstat -rn
cat /etc/netmask
cat /etc/defaultrouter

And also, on some new T5xxx system, you can't even plumb thenxge interface. They have some bugs with the Solaris 05/08 release and it will only work after apply the latest kernel patches
