Re: OT: Configuring MAC Address manually on Solaris

Do you have a netmask you need to enter.. my guess would be you do. If you really have an IP in the 200.x.x.x range and you have a "class c" address (where the netmask is 255.255.255.0) you should be fine as is.. but my guess is its less than 172.x more and you need to specify it in the /etc/netmasks file.. for example, my (old) ISP gave me a 64.x.x.x address, but it was a class C .. so I had to make /etc/netmasks entries so that I could find my default router. Can you ping your default router?

.. also trust me on the /etc/hosts file.. sendmail will be happier and when sendmail is happy, you will be more happy.. you can do ale.local. if you dont have a domain.

/etc/hosts:
200.0.0.2   ale.yourdomain.com. ale


/etc/netmasks:
200.0.0.0 255.255.255.0


/etc/hostname.hme0:
ale

/etc/nodename:
ale

/etc/defaultrouter:
200.0.0.1

/etc/resolv.conf:
domain ale.com.ar
nameserver a.b.c.d
nameserver e.f.g.h


/etc/nsswitch.conf
#(otherstuff)
hosts:  files dns
#(otherstuff)
ipnodes: files dns
#(otherstuff)

Dear people, Peter:

Finally my ISP gave me four static IP's, in order to get Internet. So I had no to get in trouble with DHCP...but in thsi new configuration I have no Internet too.

Assuming one of my IP is 200.0.0.2 I do this:
/etc/hosts/200.0.0.2   ale   (separated by a Tab)
/etc/inet/hosts/200.0.0.2   ale   (separated by a Tab)
/etc/resolv.conf --- domain ale.com.ar
                                nameserver x.x.x.x
                                nameserver y.y.y.y.
/etc/nsswitch.conf --- hosts: dns files
/etc/defaultrouter --- 200.0.0.1 (my default gateway)
Then I reboot and hme0 is Up and running....but I have no Internet.

I test in a WXP machine with the IP and MAC of my Solaris and I get
connected to Internet.
 I have no IP Filter firewall rules...so I ask you: is my /etc/files
configuration good enough ???

Thanks again to everybody !!!!

Alejandro

Hi Alejandro

just put the dhcpagent file I sent you in /etc/default.

then unplumb your dhcp interface I assume it's hme0 if not, then change it to your needs

ifconfig hme0 down
ifconfig hme0 unplumb

also kill the dhcpagent
pkill dhcpagent

wait until the dhcpagent has released its network port with the
following command.

netstat -a | grep 4999

produces the following output if dhcpagent is active

localhost.4999             *.*                0      0 49152      0
LISTEN

after you killed the dhcp agent you have to check with netstat -a |
grep
4999
until you don't get any output for port 4999

now we start from scratch

ifconfig hme0 plumb

now we configure the mac address to the one your PC has. Replace
nn:nn:nn:nn:nn:nn
with the MAC address of your PC.

ifconfig hme0 ether nn:nn:nn:nn:nn:nn

now we try to get an IP address of the ISP this will also start the
dhcpagent

ifconfig hme0 autodhcp primary

now we should have our IP address. Doublecheck with

ifconfig -a

if you got the IP address you can check what your ISP provides with

showdhcp

Good luck.

Dear Peter,

Sorry again, but you are my hope !!! I continue without getting a
dynamic IP, and I'm not a Unix/Solaris expert.
I have no the /etc/default/dhcpagent script in my Solaris 7, so I
don't know how to continue.
Briefly, I start dhcpagent (I saw it with ps -ef), after that I run
"ifconfig hme0 dhcp ping" and the output of "echo $?" is 0 (it

appears

to be ok).
Then I run "ifconfig hme0 dhcp status" and I always obtain: STATUS:
selecting, SENT: 4, RECEIVED: 0, REJECTS: 0.
I edit my ipfilter rules as you said (incoming udp/67 to udp/68 and
icmp, and outgoing everything).
When I run "snoop -d hme0" I see only incoming ARP traffic from other
external machines. But there are no any outgoing traffic from my Sun
!!! So I think my dhcpagent is not leaving my Sun box.

Please...I don't know what to do, and people is asking me for

Internet

time after time !!!
Can you tell me what to do in order to use the IP and MAC Address

from

the Windows machine that is connected succesfully via cable modem ???
Maybe is my last chance.

Thanks Peter, I know I'm dsiturbing you, sorry.

Hi Alejandro

basically you do it this way

dhcpif=hme0

ifconfig $dhcpif plumb
ifconfig $dhcpif ether 08:00:20:12:34:56
ifconfig $dhcpif auto-dhcp primary 2>&1

I did not let Solaris configure the interface (no hostname.le0 or

what

ever
for the wan side. First of all you hav to configure the dhcp agent,

so

you
would get a little bit mor then just the IP address.
See my /etc/default/dhcpagent

I have my cablemodem startscript slightly modified attached.
after starting the script you can test your dhcp settings with
the showdhcp script to see what your ISP provides.

I hope that helps

Dear People, sorry for my off-topic. I'm suscribed to a Solaris

list

but it
appears to be down, and you know a lot of Solaris, so here I am.

At

second,
thanks to Michael Lim and Peter Bickel who helped me a lot with

my

cable
modem DHCP/IP Filter problems.
I just want to know if I run this command as root:  "arp -s
<ethernet_address> pub"
it's possible to set manually a MAC Address to my Sun's NIC

connected

to

Internet.
I want to know this because, in case I still have problem

connecting

via

DHCP (I did not receive any dinamic IP), I can set the public IP

assigned

succesfully to a Windows machine via DHCP and its corresponding

Windows' MAC

Address....maybe this can be one last solution.

But first, I will follow Michael and Peter advices !!!

Thanks a lot, regards !!!

Alejandro Cabrera
