Very Computer

Hi,

I'm working on a sparc machine with a built in Ethernet 10base-T
port and an extra Ethernet card which has a 10base-2 or AUX port.
There are two interfaces preconfigured, namely le0 and le1 which
I presume that they refer to the on board port and the extra
adaptor respectively. I've also edit files hostname.le0,
hostname.le1 and hosts file to configure there name and addresses.

prtconf shows the followings :

System Configuration: Sun Microsystems  sun4m
...
SUNW,SPARCstation-5
....
     ledma, instance #0
         le, instance #0
     ....
     le, instance #1
     ...

Now, when I use ifconfig -a to check the two interfaces, I get
the following output :

lo0: flags=849<UP,LOOPBACK,RUNNING,MULTICASE> mtu 8232
        inet 127.0.0.1 netmask ff000000
le1: flags=863<UP,BROADCAST,NOTRAILERS,RUNNING,MULTICASE> mtu 1500
        inet 192.168.101.1 netmask ffffff00 broadcast 192.168.101.255
        ether 8:0:20:88:35:2a
le1: flags=863<UP,BROADCAST,NOTRAILERS,RUNNING,MULTICASE> mtu 1500
        inet 163.37.211.34 netmask ffffffc0 broadcast 163.37.255.255
        ether 8:0:20:88:35:2a

It is strange that the two interfaces have the same ethernet/mac
address,
why ?

Indeed, how can one get the ethernet/mac address of each interface
installed ?

Besides, last week, the hub port connecting the le1 interface got some
problems. I plugged the cable into another port but ping still failed to
reach other machine. Then I reboot the machine, without powering off it,
ping still didn't work. Finally, I shutdown and switch off and on the
machine again, ping is then ok. I got no clue on what is going on, could
somebody help me ?

Thanks.

  ifconfig le1 ether 8:0:21:88:35:2a

HTH

-ts

So, from the <OK> prompt its:
setenv local-mac-address? TRUE

From the OS its:
eeprom local-mac-address?=TRUE

Then reboot.

That should give discrete MACs for each interface as well.

on AIX there is a system call 'disclaim' that returns the memory to the
OS. Is there something similar on Solaris 5.5.1?
