Discovering additional network configurations

Can someone help me. While trying to install solaris 10 in my ultra 80. I keep getting a hangup while discovering additional network configurations. How can I disable this so it doesnt happen anymore.

boot cdrom -vs is supposed to take you to a functional environment,
into single-user mode, and do so in a verbose fashion.
That is exactly what the command does. Thus it's functioning properly.
To start your OS installation, just boot to the cdrom.
OK boot cdrom <enter>
If you want it to do so in a verbose fashion, use the -v command switch.
... just do not use the letter "s" in the command and it will start the install.
During this entire discussion, you never mentioned whether you even tried
to probe the SCSI bus to see whether the drives were recognized by OBP.
If OBP doesn't see them, then your system will fail back to trying to discover
a boot device on the network ( along any network pathway that could possibly exist ).

The IP subnets are not technically the same (10.1/16 and 10.2/16), but they are handled by the same router.
Normal operation and Solaris9 jumpstart is fine. I got the same problem when I tried jumpstart in the same subnet as the jumpstart server.
The Solaris10 installer is doing something unexpected when detecting setting. Something like checking that address with DHCP is the same as the one gotten initially ( I do not believe this is the problem, this is just in the area where I believe that there is problems).
Any specific hints?

Discovering additional network

hi all
im trying to install solaris 10 on my PC but it seems not working every time it hangs on the " discovering additional network ..."
i checked my harware its comatabile with solaris 10 and after many tries i removed the eathernet card but the same thing it hangs on the same statement for more than 30 min.
plz if u can help me
i am new to solaris

Have you by any chance set it up to use DHCP? If so then you might want to change that to a static entry.

Ghost Ethernet Adaptor (en2) appeared in all network configurations!

Since a few minutes, for no related reason I can imagine,
I find in all my network configurations a new Network Port:
Ethernet Adaptor (en2)
Worse than this, in all the configurations I have not
recently modified, I found that this new ghost interface
is "On".
I looked at what may have happened at the Unix level to
discover that I have a new interface named en2 which has
an Ethernet address that start like the one of my internet
Ethernet card, but which is different.
Where is this ghost "Ethernet Adaptor" coming from?

How to handle changing IPv6 network configurations

Hi,
I run a Mac Mini as a server with OS X Server 10.8.5/2.2 on it using an internet connection with DS-lite. The server runs fine on a private IPv4 and a public IPv6 assigned by the ISP thrugh my router. Now from time to time (on some really odd days 5 times a day) my ISP decides to change my IPv6 prefix and as a consequence the IPv6 of my server. This results in a warning and some services seem to work not always properly. When I handle the warning and update the network configuration (although all relevant pieces of configuration that are shown along this proces remain unchanged), everything is back to normal.
Now I wonder whether there is better way to handle changing IPv6 prefixes while everything else is unchanged? Any thougths? Thanks. Steffen

I'll add my 2 cents too Sudheer...
I suppose your versioning strategy should take into account your particular circumstances, impact analysis, ESB architecture etc...
In our case it makes sense to version the service operations because we have some consumers that want to stay on the older version & other that want to move with the changing versions...
We've noticed that SAP, with the standard delivered enterprise services also version step the service operations so you esentially have 2 service contracts but one that caters for additional fields/functionality. The consumer uses the service operation that they prefer.
The other possibility, if you are in a position to make the new fields 'optional' then you could do that without impacting all the consumers, the consumers that have the additional info to pass in the request can do so & the other consumers can carry on business as usual.
Then you could also version step the entire service, that would entail making use of a new software component version but this would entail new endpoints & depending on your architecture it could impact all your consumers. If you're using an integrated ESB architecture, your consumers would have one endpoint & the ESB would route the request to the relevant service version.
So you could minise impact on the consumers & develop a good versioning strategy depending on what your current situation is.

Best wireless network configuration with my hardware

I have a rather large property and over the last year or so I have acquired the following hardware. Up until now I have been extending my network wirelessly to get through coverage. However with the recent addition of a Time Capsule and the addition of AT&T U-Verse, I decided it was time optimize my network configuration
The Hardware:
• 1 AT&T Residential Gateway (With WiFi)
• 1 Airport time Capsule
• 2 Airport Extreme 802.11n (Gigabit Ethernet)
• 1 Airport Extreme 802.11n (Fast Ethernet)
• 1 Airport Express 802.11n (used mostly for printers)
The Computers:
• Mac Pro 8 core 2.8Ghz
• Mac Mini Core Duo 1.83Ghz
• Macbook Air Core 2 Duo 1.8 Ghz
• Lenovo T60p (with 802.11n)
• Ipod Touch
The slowest system is the Mac Mini with it's 802.11g however it is close enough to the TC / Residential gateway to wire into the network. All the other systems need to take advantage of the Wifi and have the ability to use the 802.11n speed. I'm not too worried about the ipod touch...
So I know I am reaching a point of diminished returns by constantly extending my wireless connection. Now, would it be beneficial to set the TC as kind of my main Wif access point and use eithernet to connect my Airport Extremes to extend my network?
I have the built in 802.11g of my AT&T RG disabled right now. I could create a 2nd network to allow the connection of my mini and iPog touch. but for the most part i would prefer to leave it disabled.
One thing to take into consideration. Due to the nature of AT&T U-Verse and the connection from the AT&T RG and the TC/AP Extreme bust be in bridge mode giving DHCP control to the AT&T RG.
Whew. Any thoughts?
Message was edited by: Vermifuge

Ethernet as many routers as possible. Place secondary routers in bridge mode. Separate the N devices to a router (TC) from N+B/G devices should go to the secondary routers. Once done set wireless to create their own network. All N computers to N router ie TC and the remainder to which ever secondary router you prefer.

Error during Checking Network Configurations Requirements in RHEL3 VM

Hi,
I have a Red Hat Enterprise Linux Image Virtual Machine on my desktop which uses Fedora Linux. I have set this up using VMplayer.
I need to install Oracle 10g on the RHEL VM.
As the RHEL VM does not have X Windows, I am connecting to it from the Fedora Linux to do the installation.
During the Product-specific Prerequisite checks:
Checking Network Configurations Requirements throws an error,
Please find it below:
Actual Result: Unknown Host Exception has Occured :rhel3vm:rhel3vm
Check complete: The overall result of this check is: Not executed <<<<
Recommendations: Oracle supports installations on systems with DHCP-assigned public IP addresses. However, the primary network interface on the system should be configured with a static IP address in order for the Oracle software to function properly.
The Fedora Linux gets the IP address from the DHCP and allocates an IP address to the VM.
However, when we set both of them as static and the problem still persists, and also when we set the fedora as dynamic and RHEL VM as static, the issue is not resolved.
Any help will be truely appreciated. Thank you.

We were running a non-DHCP (static IP) configuration and ran into this issue. We discovered that the hostname and FQDN were not correctly specified in the /etc/hosts file.
Fixing the hosts file to correctly reference the IP resolved the issue.
Hope this helps...

Additional info:
I have connected 2 PCs with LAN (Ethernet) cable and want configure them for exchanging files. Both running Arch Linux. I am following the Network Configuration wiki page from the beginning. Didn't have luck with DHCP/dynamic IP, so trying Static IP this time. Restarting the pc with network.service enabled results in same error (in systemctl --failed). Same error message on both PCs.
Trying to run ExecStart lines one by one:
$ sudo /sbin/ip link set dev lan up
$ sudo /sbin/ip addr add 192.168.1.2/24 dev lan
RTNETLINK answers: File exists
$ sudo /sbin/ip route add default via 192.168.1.1
RTNETLINK answers: File exists
Does this mean there already is IP address and route assigned? If so, how to find out which service has done that? Do I need to remove it? Am I following the right wiki page (didn't find another)?
What am I doing wrong and how can I correct this error? / Point me in right direction.

Please help about OVM network configuration

I have ready RAC OVM templates and below is the instructions.
Can someone explain this to me?
I want to create a OVM server and OVM manager on virtualbox. But I couldnt und network configurations.
Following are the non-standard requirements for your OVM setup:
The VMs must be able to interact with the OVM server (Dom0) at IP address 192.0.2.1
The OPVM server (Dom0) must supply NTP and DNS services to the DB VMs
The OVM server must be configured with 3 virtual bridges (virbr0, virbr1, virbr2) to support the different Database Machine networks.
Here are some notes, assumptions and requirements associated with these VMs:
1. The public network interfaces on all the VMs occupy addresses in the 192.0.2.X range. The private storage network and cluster interconnect on all the VMs occupy addresses in the 192.168.1.X range.
2. All the VMs assume access to NTP and DNS services provided by servers at 192.0.2.1. One way to provide these services is to configure a bridged network interface on 192.0.2.1 under Dom0 and to configure NTP and DNS services on Dom0. Another way is to create an additional VM with a primary network interface on 192.0.2.1 which offers the required services.

Then I will import some OVM templates to that system.
No - not possible using Virtualbox - as noted, OVM and Virtualbox are different technologies and an OVM install will destroy the native OS.
I believe you are confusing technologies and terms. If I understand your needs, you are wanting to install Virtualbox on your OS, then create VMs using Virtualbox and/or import Virtualbox VM templates. Note that Virtualbox VM templates are different than OVM VM templates - the latter can only be installed on OVM Server.

Host and VMs network configuration

Hi,
We have additional Network cards on the Host hyper-v server. Does it make sense to configure Host and VM network
in this way?
Host network configuration for Hyper-v virtual network switch:
1NIC ---
2NIC --- host_team_1
3NIC ---
4NIC --- host_team_2
VM network configuration:
host_team_1 ---
host_team_2 --- VM_team_1
Would we benefit from this configuration?
Thanks

It has to be in this way:
1NIC ---
2NIC --- host_team_1
3NIC ---
4NIC --- host_team_2
VM network configuration:
host_team_1 ---
host_team_2 --- VM_team_1
I understand your point. Just idea is if we have 4 physical NICs on host server for VMs, to configure 2 teams on host server and then one team on virtual machine.

Multihomed network configuration

So, when I say multihomed what I really mean is that Macbook Air is configured to use two network interfaces -- Wi-Fi and USB ethernet -- in one Location. Each interface is configured to work on a different subnet. In fact, wi-fi is assigned a public IP address of 195.88.xxx.xxx, and USB ethernet NIC a private address of 192.168.0.252/24. Wi-Fi is en0, and USB ethernet is en2. Both interfaces are in active state.
My goal is to have MBA to route all traffic to en0, except for 192.168.0.0/24 network which I want to go via en2, the USB ethernet card.
The topology is pretty simple:
Linux Laptop <--- Linksys Cisco Router <---   en2 via <--- MBA ---> via en0   ---> Linksys Cisco Router ---> <Internet>
Essentially, I need to put en2 on the ethernet segment where the Linux laptop is to be able to talk to it directly. No routing needed. This apporach works without any problems in Linux environment. However, on Mac OS X it doesn't work and it makes me wonder why.
A few details on what happens on the network:
tcpdump output from Linux machine (it is assigned 192.168.0.253/24):

I tried Service Reorder (in System Settings->Network) and set en2 as the first device on the list, or one position behind en0. It doesn't change anything.
My question is similar to these discussions:
https://discussions.apple.com/thread/2297388?start=0&tstart=0
https://discussions.apple.com/message/9984744?messageID=9984744#9984744?messageI D=9984744
and in one of them it is implied that no extra configuration should be made beyond what I've already done, but clearly Mac OS X doesn't see ARP request reply from the Linux machine.
BTW, firewalls are down on both systems.
I also found this network configuration manual for Princeton University campus network
http://www.net.princeton.edu/mac/network-config-x-10.8/caveats.html#ip-weakend
that claims that Mac OS X actually cannot do what I'm attempting to and refers to Weak End System Model which in essence is described in RFC4907 as:
In the Weak End System model, addresses refer to a host. As a
        result, packets sent on an outgoing interface need not
        necessarily have a source address configured on that interface,
        and incoming packets whose destination address does not
        correspond to the physical interface through which it is
        received are accepted.
That could explain why ARP request reply never makes it back to Mac OS X.
So, any ideas? Any tips?
I'd highly appreciate help of the community because I'm stuck

I dont have a PSC2210 but one of the documents I saw said to go to the front panel of the printer, press the Setup button, press 6 and then press 1 to print the Network Configuration page.

Network configuration Solaris 10.

Hi all,
I got my solaris up and running with Audio and graphics working fine. Now I need to setup internet. I know the following details. Can anybody help me how to set this information. In linux I would, network configuration tool and on windows, I chang the TCP/IP properties. I don't know what to do in solaris.
I ahve the following information.
1) My IP Address
2) Subnext mask
3) DNS
4) Primary gateway
5) Sec. Gateway.

If your IP is dynamic, Solaris should get you connected to web, without your intervention. Just make sure the DHCP client is running (it runs, by default). Also check this compatibility list: http://www.sun.com/bigadmin/hcl/data/sol/components/views/networking_all_results.page1.html
If everything looks good, you can try "inetmenu" tool to get a valid IP address. More information is available at OpenSolaris web site: http://opensolaris.org/os/community/laptop/inetmenu/

Why does 10.8 take so long to discover Wifi networks?

I've noticed recently that it takes a very long time for my MacBook Pro 6,2 OS X Mountain Lion 10.8.2 to discover WiFi networks.
I open the laptop up, or wake it up from sleep, and the wifi takes 30 secs to more than 1 minutes to find any WiFi networks. It doesn't maintain the connection to the network it was connected to before the last time it went to sleep.
The WiFi icon in the upper left has no bars, all greyed out, nothing moving. When I click on it, the context menu that drops down just says "no network selected".
Interestingly, if I turn WiFi off, wait a few seconds, then turn it on again, it works fine, connects very quickly.
Is anyone else having these problems? I would very much like to get this resolved. I primarily use my computer for webbrowsing, so when I open it and have to sit there for a minute before any networks are found, then I have to go in and select my network, it becomes very frustrating.
Thanks

I've noticed recently that it takes a very long time for my MacBook Pro 6,2 OS X Mountain Lion 10.8.2 to discover WiFi networks.
