sun workstation nic card

I have an older sun workstation that was just moved to a different location.  I am trying to configure it to connect to the network in its new location.  I am not well versed on unix commands.  I need to know what command to use to show its current ip address and mac address.  I would also like to know what kind of network card it has.  speed and duplex settings.  It was working in its old location.  Unfortunately i cannot find the old switchport configs.

thanks!

Use "ifconfig -a" to show you all the interfaces... if its an older Sun, it will probably have one or more hmeX interfaces, although you'll likely be interested only in hme0.  Your specific interface will look something like this:

eri0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 192.168.1.114 netmask ffffff00 broadcast 192.168.1.255

This tells you that the IP is 192.168.1.114

To find the gateway, do "netstat -nr" (or "cat /etc/defaultrouter")


bash-2.05$ netstat -nr

Routing Table: IPv4
  Destination           Gateway           Flags  Ref   Use   Interface
-------------------- -------------------- ----- ----- ------ ---------
192.168.1.0          192.168.1.114        U         1  37873  eri0
224.0.0.0            192.168.1.114        U         1      0  eri0
default              192.168.1.254        UG        1 520147  
127.0.0.1            127.0.0.1            UH        33764114  lo0

bash-2.05$ cat /etc/defaultrouter
192.168.1.254

The line containing "UG" in the Flags column is the default route.

To reconfigure the interface/gateway, do the attached commands.

To make it permanent you will need to edit a few files:

/etc/hosts
/etc/hostname.<interfacename>
/etc/defaultrouter
/etc/netmasks


ifconfig hme0 <new IP> netmask <your netmask>
route add default <new gateway IP>

This should help and i will try this tomorrow.  What about determining the network card properties for example duplex mode and speed?

thanks

After you bring it up successfully, look in /var/adm/messages for the word "duplex":

bash-2.05$ grep -i duplex /var/adm/messages
/var/adm/messages.1:Nov 29 03:01:10 my.server.net eri: [ID 517527 kern.info] SUNW,eri0 : 100 Mbps full duplex link up

It will say what speed and duplex it came up at.  If you need to set it, use the ndd command, and you can make it permanent by editing /etc/system.  Personally I've had the best success just setting autonegotiate on both the switch and server side, but here are the commands to change it:

*****************************************************************************
To force full duplex operations, in /etc/system add:
*****************************************************************************
*   NO Auto-Negotiation-Protocol:
*   Force to 100BaseT Full Duplex:
set hme:hme_adv_autoneg_cap = 0
set hme:hme_adv_100fdx_cap = 1
*****************************************************************************

or to do it on the fly:

ndd -set /dev/hme instance 0            #<- select hme0
ndd -set /dev/hme adv_100fdx_cap 1      #<- enable full duplex
ndd -set /dev/hme adv_autoneg_cap 0     #<- turn off auto-neg
