MAC address question - Solaris Intel

I am running Solaris 8 for Intel and using the Intel Ether Express Pro 100TX (iprb driver) network card and I need to permanently override the card's MAC address. Temporarily, I have used ifconfig to change the card's ether address, but as you know, that's only good until you reboot. The setting isn't in the iprb.conf file (and it's not like I have the luxury of having an OpenBoot eeProm).
If anybody knows, I appreciate your help. - Ken

The Mac addresses in intel cards are burnt into a serial eeprom on the card. So you can't change it. :-)

Mac address in solaris

Hi all,
Actually to find the Mac address in solaris OS , We need to do it in super user mode.
But without move to root mode , how can we get the mac address through command.
Is there any way,
If anybody knows please reply.
Thanks.

Virtual MAC-Address on Solaris 10 update 9

Hi,
i'm installing Solaris 10 update 9 on UCS B-Series (B230 M2 or B440 M2) with M72KR-Q Adapter. We create the Service Profile with vNIC associated to vNIC Template. The vNIC Template use the MAC Pool Address configurated.
When we run ifconfig -a on Solaris we can view only the original MAC-Address instead of Virtual MAC-Addres. Is this correct?
Thanks in advance

When you say the "original" MAC are you referring to the Hardware Default?
Ensure your MAC pool has available addresses also. You can also test unbinding the vNIC template from the Solaris service profile, and manually assigning a MAC address (watch for overlap) to the vNIC and see if that pushes to the solaris host.
If that works, then you have a pool/template issue. If not, we'll need to investigate further.

Robert

Setting MAC-address on wireless Intel 2200 BG card

I have a wireless Intel 2200 BG card in my laptop. I have installed the ipw2200-package, and it appears to be working. The module ipw2200 loads just fine and iwconfig gives me this:
eth1 radio off ESSID:off/any
Mode:Ad-Hoc Channel:0 Cell: 00:00:00:00:00:00
Bit Rate=0 kb/s Tx-Power=off
RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
However, i have not been able to set the MAC-address. I am at my parrents house, and their ISP have enabled a MAC-filter on the wireless router. So i can't access the router with my wireless card.
if i do a "ifconfig eth1", i can see that the MAC-address of the card is 00:0E:35:FE:2D:1A
Then i do:
ifconfig eth1 hw ether 00:50:BF:9C:D7:A5
I do not get any error-messages, but when i do a "ifconfig eth1", the MAC-address is still 00:0E:35:FE:2D:1A
Any suggestions on how i can set the MAC-address of my card?

It isn't my router, it is owned by our ISP. They might give me the username/password if i ask, but i thought setting the MAC-address on my card would be an easy thing to do. I have done it on my wired ethernet card, so i am using that one right now. But wireless would be more fun.

Router MI424WR - Device Names to MAC Addresses Question

I have Verizon FiOS with an ActionTec MI424WR Router. I have many devices connected to it on our home network: ipods, ipads, nook, kindles, laptop, roku, and a desktop.
For each device, I found its MAC address. Then I logged into the router and went to "My Network." There, I renamed each device (for example, from "android-alsdfjl3kljasdf" to "JonKindle" and "new-host-4" to "MaryIpad"). That way, I'll be able to go to the parental controls rules screen and assign each device to rules as I like.
Problem:
The names keep changing back to "android-alsdfjl3kljasdf" and "new-host-4". Not only that, but somehow, the MAC addresses keep changing. Is there a way to keep that from happening?
I thought MAC addresses were assigned to a piece of hardward and didn't change. Can someone please enlighten me?
Thanks,
smy

The trick to make the [name, MAC address] permanent is to assign a static DHCP lease to each device. Otherwise, when the lease expires and the device is no longer active, the router forgets everything about it.
As for changing MAC address, you are correct, they shouldn't change.
If you have multiple "Android-xxx" devices they may be coming up in a different order, thus creating the appearance of changing addresses. Make a list of every active MAC address and attempt to correlate it to your devices. The next time you think one changed, look and see if it's on your list.
MAC addresses can be changed by the user on some devices, however this is typically only done to "play" with a network or circumvent security features.
Good Luck.

Hyper-V Failover Clustering MAC Address Question

Hello,
Can someone please explain how MAC address assignment works in a hyper-v cluster? I have a couple machines that need to have a static MAC address assigned and want to know how the cluster handles it when the VM is Live migrated to a new host. Thanks in advance.

Hi ice2921,
Yes, after export and import to another Hyper-V host, the dynamic MAC address of the VM changes
after export and import to another Hyper-V host, the dynamic MAC address of the VM changes, this is by design.
As Alexey offered article, to have a dedicated Mac Address for the VMs they should be set to static MAC address, it is normal the dynamic assign to vm when the all the Hyper-v
host as there own MAC address range , this is by design of Hyper V and failover clustering when using Dynamic MAC addresses for VMs.
If you are using 2008R2 Hyper-V failover and you found it often lost the network connection and configuration, please install the hotfix.
Reinstalled the integration services
The network connection of a running Hyper-V virtual machine may be lost under heavy outgoing network traffic on a computer that is running Windows Server 2008 R2 SP1

HT4262 wds MAc address question

I have a wds network working with
- a time capsule as main
- a n exporess as relay
- an airport extreme as end node
it is working but slow; as I was wondering if there was any traffic between the end node and the main station i ask myselve:
should the remote stations mac address be allowed by the relay only or the relay and the mainstation?
any toughts on this?
tx
diederik

it is working but slow;
Unfortunately, that is what WDS does. The bandwidth on the network is cut in half for each relay or remote. Since WDS only runs at "g" wireless speeds, when you have a relay and remote configured, the entire network runs at only 25% of normal "g" wireless speeds. This would be about 13-14 Mbps link speed. The "actual" throughput would probably be around 6-7 Mbps.
I was wondering if there was any traffic between the end node and the main station
It depends on how you have configured the main base station and remote. If you "allow" the remote to connect to the main, then the remote will try to "hop" over the relay, so there would be direct traffic between the remote and main.
If you do not "allow" the remote to connect to the main, then the remote must be allowed to connect to the relay. In this case, there will not be direct traffic between the main and the remote. The main connects to the relay and relay connects to the remote.
any toughts on this?
Avoid WDS if possible

MAC address when solaris is in run level 0 mode

Hi
My system is at level 0 mode with the ok prompt. How to identify its MAC address?
thx

Hello
"ok" prompt means the operating system has not been loaded yet on a Sparc machine?!
In this state you can get the MAC address by typing

DNS and Static IP Address Question on Solaris v10 X86

I�ve recently installed Solaris v10 X86 and have two questions. The system is a Dell E521 with 4GB RAM and 1GB SysKonnect NIC, and internet is provided via a cable modem, that�s plugged into a Netgear router, and the Solaris 10 box is plugged into the Netgear router via a CAT5 ethernet cable.
1. I can connect to my router login page using the following URL:
http://192.168.1.1/start.htm and I can also connect to various web pages such as yahoo, if I first "ping yahoo.com" (on another machine that�s internet enabled) and then plug the web site�s ip address into the Solaris/Mozilla browser. So it appears that I haven�t been successful at pointing the Solaris x86 at a DNS server to resolve the DNS name.
2. I've purchased a commercially available software package and it requires a static ip address for this Solaris x86 server. If the ip address changes, it�ll stop working by design and require that I reacquire the license file. When connecting through this Netgear router, how do I lock this Solaris v10 x86 server into a specific ip address? (the ip address floats presently when cycling my PC�s on/off) presently, and assume the Solaris box will too, usually through an ip range of 192.168.1.<1 through 5>

The NIC is a SysKonnect 9821 1GB Ethernet card. The drivers in Solaris 10 were apparently very old and didn't install drivers or configure/plumb when I installed Solaris 10, so I downloaded the
latest drivers (hard to find!), followed the instructions and got the NIC drivers installed and then plumbed.
My router's ip address appears to be 192.168.1.1 and in one of the articles I've read, there is a recommendation to create a file (touch) within /etc named defaultrouter and enter the router's ip address. I did this, and the file now contains:
192.168.1.1
I also read where another file called resolv.conf needed to be pointed to a DNS server, which in this case, according to my Netgear router, and according to ipconfig/all on another WinBox on the same network, also shows the same 192.168.1.1 address for the DNS, so I created that file too (wasn't there) and it contains:
nameserver 192.168.1.1
There is a host name file called hostname.skge0 and it contains one line:
INTHOST
There is a hosts file, and it contains:
127.0.0.1 localhost loghost homex86
192.168.1.3 INTHOST
There is a netmasks file, and other than the commented out lines, it appears to contain one relevant line:
192.168.1.0 255.255.255.0
There is a nsswitch.conf file and other than the commented out lines, it contains:

Finally, I've also seen some advice using the folling command (and I tried it):
"route add default 192.168.1.1" as an alternative method of setting up route table
The only other command I've tried is:
"ifconfig skge0 192.168.1.1 netmask 255.255.255.0 up" but I suspect that was redundant as the plumb command I used to get the NIC functioning earlier probably already provided what was needed.
Finally, on this small network, I ran an ipconfig/all on a Windows based PC, to see what network settings were reported through the wireless connection, and this is an excerpt of that information:

.mac mail question:I have an old emac without an intel chip...

.mac mail question:I have an old emac without an intel chip...I have a .mac email account, I would like to be able to have my emails automatically forwarded to a gmail account. I cannot access icloud with this old machine, any ideas? thanks! and aloha!

Hello,
But you can setup iCloud email on you old Mac!
Do not delete the old account yet. sign up for an iCloud account if you haven't.
I understand .mac mail will still come through. Do not delete the old account yet.
You cannot use .mac or MobileMe as type of Account, you have to choose IMAP when setting up, otherwise Mail is hard coded to change imap.mail.me.com to mail.me.com & smtp.mail.me.com to smtp.me.com, no matter what you try to enter.
iCloud Mail setup, do not choose .mac or MobileMe as type, but choose IMAP...
On second step where it asks "Description", it has to be a unique name, but you can still use your email address.
IMAP (Incoming Mail Server) information:
• Server name: imap.mail.me.com
• SSL Required: Yes
• Port: 993
• Username: [email protected] (use your @me.com address from your iCloud account)
• Password: Your iCloud password
SMTP (outgoing mail server) information:
• Server name: smtp.mail.me.com
• SSL Required: Yes
• Port: 587
• SMTP Authentication Required: Yes
• Username: [email protected] (use your @me.com address from your iCloud account)
• Password: Your iCloud password
Also, you must upgrade your password to meet the new criteria: 8 characters, including upper and lower case and numbers. If you have an older password that does not meet these criteria, when you try to setup mail on your mac, using all of the IMAP criteria listed above, it will still give a server error message. Go to http://appleid.apple.com then follow directions to change your password, then go back to setting up your mail using the IMAP instructions above.
Thanks to dpepper...

ICloud to Mac Address Book - Two Questions

Okay, I have learned/accepted that iCloud is not the sync'ing deal that MobileMe was (missed that in the fine print as I have been a loyal .mac user from its inception and like the MM syncing). I understand that everything is updated in the cloud and pushed to various devices (for me, iPhone 4S, new iPad and 2009 MBP). So, how is it possible for my iCloud address book to have more contacts than my MBP address book? Wouldn't all of the ones in iCloud be pushed to the MBP? The only thing I can think is that before I understood the concept that there are two address books resident on the MBP, I starting deleting what I thought were duplicates since I wasn't able to merge them due to two different sources. I could not find a way at that time to tell me which line was from what source. Then, once I get the two address books matching - mostly to ensure that I am not missing anything in the iCloud one - what purpose does the Mac based address book serve? I just had a nightmare of dragging various cards from my iCloud address page on the right into the iCloud group on the left and only to realize after doing at least 20 cards that after the first one, the left page registers back up putting the Mac based group across from the iCloud contact list so I dropped many of them into the Mac group instead of the iCloud group. The iCal doesn't maintain a Mac version and an iCloud version, why does the address book? BTW, all software on all devices is up to date as of this posting.

Please pardon what may be a silly question. This is my first ever post...
I was thinking about deleting "On My Mac" address book per your above instructions, and sticking with the one iCloud contacts. The problem I am afraid of running into is this: In iTunes, when I sync contacts, the groups that show available for syncing all come from "On My Mac". If I delete from the Mac, will that make my "Contacts" icon on my iPad 'dead'? Thereby, forcing me to log onto iCloud to view my Contacts, instead of a handy shortcut???
Or will I simply get to forgo the iTunes syncing... and the "contacts" icon on my iPad will reflect what was synced thru iCloud?
If the latter is true, does that simply mean I will need to recreate my "groups" in iCloud?
Thanks in advance, I certainly need some guidance.

Solaris local-mac-address setting

Hi all,
Having 10gR2 Clusterware and RAC on two Solaris 10 sparc, is it required to set the EEPROM settng local=mac-address? to true so that each network card will use its own MAC address instead of the server unified MAC address? Did anyone see it in Oracle documentation for Solaris?

In order to avoid MAC address conflicts between the primary and standby NIC's, a unique
ethernet MAC address must be assigned to each network interface (NIC) on the server. On
Solaris, this can be done by setting the "local-mac-address?" PROM variable to TRUE (the
default value is FALSE) on each cluster node.

Considering buying time capsule have some Mac address related questions

Hi,
as mentioned above I'm considering buying a time capsule for backup and wifi purposes.
My internet providers connection depends upon a set Mac address from the first computer you register with, the system works with any router which then clones the MAC address and issues a wifi signal to all computers. I don't have access to the origional computer which we registered our connection on, it went to the great computer graveyard in the sky and I have no record of the Mac address.
I Would like to use the time capsule system as a router and remove my existing router. my questions
can the time capsule spoof or clone a Mac address ?
I Don't want to be offline while we deal with technical support as they are quite inept sometimes.
Is it in this case really plug and play ? Can I just plug it in set it up on my Mac and away it goes where other non Apple devices can use the wifi.
Without the existing router the cable that comes into the house connect directly to the ' original ' computer and the Internet only works on that computer
hope someone can help me I would like to purchase this device

The Time Capsule cannot clone a MAC address, so quite simply, the product is not for you.

Change MAC address on Intel Mac?

Is it possible to change the MAC address of an Apple computer using an Intel chip and if so, how?
Open Firmware on PPC machines made it easy. I don't know about EFI.

Hello Kappy,
Why is it not a good idea to change the MAC address?
Thanks Kevin
Because it is intended to be a globally unique identifier of hardware. The MAC address can be changed on modern systems but why? See here for more info http://en.wikipedia.org/wiki/MAC_address
Here are some reasons a person may want to change their MAC address. None of them sound like legitimately valid reasons.
From http://www.irongeek.com/i.php?page=security/changemac
To get past MAC address filtering on a router. Valid MAC      addresses can be found by sniffing them and then the deviant user could      assume the MAC of a valid host. Having two hosts on the same network can cause some network stability problems,      but much of the time it's workable. This is one of the reasons why MIC      Address filtering on a wireless router is pointless. An attacker can just      sniff the MAC address out of the air while in monitor mode and set his WiFi      NIC to use it. Interestingly, a lot of hotels use MAC filtering in their      "pay to surf" schemes, so this method can be an instant in for cheap skate      road warriors.
Sniffing other connections on the network. By assuming      another host's MAC as their own they may receive packets not meant for them.      However, ARP poisoning is generally a better method than MAC spoofing to      accomplish this task.
So as to keep their burned in MAC address out of IDS and   security logs, thus keeping deviant behavior from being connected to their   hardware. For example, two of the main things a DHCP server logs when it      leases an IP to a client is the MAC address and host name. If you have a      wireless router look around on it's web interface for where it logs this      info. Luckily there are tools to randomize this information (MadMACs).
To pull off a denial of service attack, for instance   assuming the MAC of the gateway to a sub net might cause traffic problems.      Also, a lot of WiFi routers will lock up if a client tries to connect with      the same MAC as the router's BSSID.

ACE multiple mac-address for a single IP (solaris ipmp)

Dear All,
We are triing to load ballance smtp traffic to solaris mail servers that are using ip multipath in bridge mode configuration.Multipath is configured so that only one of the redundant interfaces replies to arp request. Therefore all of the traffic come to the solaris from the ACE on the primary interface, but solaris uses the secondary interface too with different mac address to answer.The load ballancing working correctly it does not matter if solaris answers the request with its primary (MAC known by ACE) or secondary interface (MAC not know by ACE). But if the solaris wants to create a tcp session that is not balanced but go through the ACE with secondary interface which mac-address is not know by ARP in the ACE, the packets are silently discarded. There is no logs about it.
Please if someone could know this behavior answer.
Regards,
szicsu

If you do a 'show np 1 me-stat '-socm'' you will see a counter catching the packet drops.
Drop [mac lookup fail]: 30 0
Drop [route lookup fail]: 14316 0
We can't setup connection for unknown mac-address or if we do not have a route.
We need to first learn the mac-address through the arp request/response mechanism.
This is during this process that the encap id is associated with the mac-address.
Without that encapid we can't create the connection to flow the traffic.
You can try to disable normalization to see if that could help, but I can't guarantee it.
Gilles.
