Stuck assigning IP

Solaris 9 on x86:  I have a 3com 3509c  NIC in there (it's on Solaris's HCL).
It finds the NIC during installation.  However, when I try to let it get an IP (via DHCP) it cant get one.  Even though my DHCP server is working perfectly.

So I assigned an IP manually during installation.  Seems ok, but when the system rebooted, it looks for a DHCP server. Why does it do this when I specified static?

I log into the system, do an ifconfig -a.  It shows the loopback, and it shows my NIC as e1x10.
But the IP is not assigned to it.
Any ideas?
Thanks

Well I got an IP assigned to the Nic.
ifconfig elxl0 inet 192.168.4.4 netmask 255.255.255.0 up

How do I specify DNS and default gateway settings?  Still curious as to why the DHCP server cant get through....

You can set the gateway by placing the IP in /etc/defaultgateway and the namservers can be specified in /etc/resolv.conf. If the install didn't already do so you man need to modify /etc/nsswitch.conf and include dns in the search list for hosts.

I don't know if it applies to Solaris with a 3c509, but on Linux you must use a 3Com diagnostic tool to disable the card's PnP mode and set it for a fixed IP. Otherwise the card won't work properly.

To setup your Solaris box as the DHCP client, please read the instructions in the following page:

http://www.experts-exchange.com/Operating_Systems/Solaris/Q_20678299.html

The instructions in the about page still apply to Solaris x 86, you need to remember to
replace the real insterface name (eg, iprb0).


PS: You might need to run "/usr/sbin/sys-unconfig" to  
      unconfigure the Solaris box and then reconfigure it.

In case of the DHCP server failed to pass the DNS server infor to the client, or the client failed to get the DNS infor from the DHCP
server. (It might be a bug!).

Manually add the 'nameserver xxx.xxx.xxx.xxx' entries to resolv.conf after booting.  and also  check the/etc/nsswitch.conf
 to make sure that the "hosts" record looks like:

hosts:     files dns [NOTFOUND=continue]

What does it mean to be "Always On"?

Which model of 3com are you using, have a look at:

Or do a search on the web for your versioin of NIC.

Could you please write your hostname in the file
/etc/hostname.elxl0 (those are "L"s not "1"s), please be careful.
Then, open your /etc/hosts file and match the specified hostname with the IP address of your preference.

It work Ok on the next reboot. I don't thing it is realted with the hardware itself.

Hope this helps.
