How to configure network with just 1 ethernet adapter?

I was looking for a guide which would talk about how to configure your network in case if you have only 1 Ethernet adapter. Is it mandatory to have more than 1 network card to configure multiple ports? If not, what are the options available to deploy a Virtual Machine that can have applications which are available over the network. I don't have a separate network i.e. public network as well as management network is of same IP range.
I am having 2 node cluster using NFS for pools as well as repository.

I am having 2 node cluster using NFS for pools as well as repository. I strongly recommend you get at least one more physical NIC for your server, if not two: running NFS and the cluster heartbeat and the guest traffic all over the same network is going to put a lot of data down the wire and you may land up in a situation where the cluster traffic is overwhelmed and a node reboots. You need to be very careful in this situation. Network cards are cheap and you should have at least two or three, I reckon.

How to configure network virtualization in SCVMM 2012 R2 with two host

hi everyone... can you teach me how i configure networking in my infrastructure..
i am getting confuse that i have 2 phisical server, i don't know to set the netwokring in scvmm. Every best practice, i found in internet is using more than 2 physical server.
i have been tried before with the networking which i want..but it failed...
any one help me please...

This whitepaper should explain the required steps to get this working.
http://gallery.technet.microsoft.com/Hybrid-Cloud-with-NVGRE-aa6e1e9a
The whitepaper will use more than two hyper-v hosts, but you'll get the picture.
You can have 1 host to run your NVGRE VMs, while the other host should be dedicated to run the virtualization gateway VMs.

I just got a fc7 yamaha expression pedal and can't figure out how to configure it with mainstage or logic.

I just got a fc7 yamaha expression pedal and can't figure out how to configure it with mainstage or logic. I'm using a Gio pedal.

Hi
You will need to map the "Expression Pedal" to the Waa pedal. There are several ways you could do it, here's one:
In Layout Mode, add a Pedal Screen control, and Assign it to the in-coming MIDI from the GiO.
In Edit mode, select the Screen Control, and click the "Map Parameter" button. While this is active click on the Wah pedal in the PedalBoard plugin. Turn off 'Map Parameter".

How to configure sso with SSL step by step

Purpose
In this document, you can learn how to configure SSO with SSL. After user have certificate installed in browser, he can login without input username and password.
Overview
In this document we will demonstrate:
1.     How to configure OHS support SSL
2.     How to Register SSO with SSL
3.     Configure SSO for certificates
Prerequisites
Before start this document, you should have:
1.     Oracle AS 10g infrastructure installed (10.1.2)
2.     OCA installed
Note:
1.     “When you install Oracle infrastructure, please make sure you have select OCA.
2.     How Certificate-Enabled Authentication Works:
a.     The user tries to access a partner application.
b.     The partner application redirects the user to the single sign-on server for authentication. As part of this redirection, the browser sends the user's certificate to the login URL of the server (2a). If it is able to verify the certificate, the server returns the user to the requested application.
c.     The application delivers content. Users whose browsers are configured to prompt for a certificate-store password may only have to present this password once, depending upon how their browser is configured. If they log out and then attempt to access a partner application, the browser passes their certificate to the single sign-on server automatically. This means that they never really log out. To effectively log out, they must close the browser.
Enable SSL on the Single Sign-On Middle Tier
The following steps involve configuring the Oracle HTTP Server. Perform them on the single sign-on middle tier. In doing so, keep the following in mind:
l     You must configure SSL on the computer where the single sign-on middle tier is running.
l     You are configuring one-way SSL.
l     You may enable SSL for simple network encryption; PKI authentication is not required. Note though that you must use a valid wallet and server certificate. The default wallet location is ORACLE_HOME/Apache/Apache/conf/ssl.wlt/default.
1.     Back up the opmn.xml file, found at ORACLE_HOME/opmn/conf
2.     In opmn.xml, change the value for the start-mode parameter to ssl-enabled. This parameter appears in boldface in the xml tag immediately following.
<ias-component id="HTTP_Server">
<process-type id="HTTP_Server" module-id="OHS">
<module-data>
<category id="start-parameters">
<data id="start-mode" value="ssl-enabled"/>
</category>
</module-data>
<process-set id="HTTP_Server" numprocs="1"/>
</process-type>
</ias-component>
3.     Update the distributed cluster management database with the change: ORACLE_HOME/dcm/bin/dcmctl updateconfig -ct opmn
4.     Reload the modified opmn configuration file:
ORACLE_HOME/opmn/bin/opmnctl reload
5.     Keep a non-SSL port active. The External Applications portlet communicates with the single sign-on server over a non-SSL port. The HTTP port is enabled by default. If you have not disabled the port, this step requires no action.
6.     Apply the rule mod_rewrite to SSL configuration. This step involves modifying the ssl.conf file on the middle-tier computer. The file is at ORACLE_HOME/Apache/Apache/conf. Back up the file before editing it.
Because the Oracle HTTP Server has to be available over both HTTP and HTTPS, the SSL host must be configured as a virtual host. Add the lines that follow to the SSL Virtual Hosts section of ssl.conf if they are not already there. These lines ensure that the single sign-on login module in OC4J_SECURITY is invoked when a user logs in to the SSL host.
<VirtualHost ssl_host:port>
RewriteEngine on
RewriteOptions inherit
</VirtualHost>
Save and close the file.
7.     Update the distributed cluster management database with the changes:
ORACLE_HOME/dcm/bin/dcmctl updateconfig -ct ohs
8.     Restart the Oracle HTTP Server:
ORACLE_HOME/opmn/bin/opmnctl stopproc process-type=HTTP_Server
ORACLE_HOME/opmn/bin/opmnctl startproc process-type=HTTP_Server
9.     Verify that you have enabled the single sign-on middle tier for SSL by trying to access the OracleAS welcome page, using the format https://host:ssl_port.
Reconfigure the Identity Management Infrastructure Database
Change all references of http in single sign-on URLs to https within the identity management infrastructure database. When you change single sign-on URLs in the database, you must also change these URLs in the targets.xml file on the single sign-on middle tier. targets.xml is the configuration file for the various "targets" that Oracle Enterprise Manager monitors. One of these targets is OracleAS Single Sign-On.
1.     Change Single Sign-On URLs
Run the ssocfg script, taking care to enter the command on the computer where the single sign-on middle tier is located. Use the following syntax:
UNIX:
$ORACLE_HOME/sso/bin/ssocfg.sh protocol host ssl_port
Windows:
%ORACLE_HOME%\sso\bin\ssocfg.bat protocol host ssl_port
In this case, protocol is https. (To change back to HTTP, use http.) The parameter host is the host name, or server name, of the Oracle HTTP listener for the single sign-on server.
Here is an example:
ssocfg.sh https login.acme.com 4443
2. Restart OC4J_SECURITY instance and verify the configuration
To determine the correct port number, examine the ssl.conf file. Port 4443 is the port number that the OracleAS installer assigns during installation.
If you run ssocfg successfully, the script returns a status 0. To confirm that you were successful, restart the OC4J_SECURITY instance:
ORACLE_HOME/opmn/bin/opmnctl restartproc process-type=OC4J_SECURITY
Then try logging in to the single sign-on server at its SSL address:
https://host:ssl_port/pls/orasso/
     3. Back up the file targets.xml:
cp ORACLE_HOME/sysman/emd/targets.xml ORACLE_HOME/sysman/emd/targets.xml.backup
4. Open the file and find the target type oracle_sso_server. Within this target type, locate and edit the three attributes that you passed to ssocfg:
·     HTTPMachine—the server host name
·     HTTPPort—the server port number
·     HTTPProtocol—the server protocol
If, for example, you run ssocfg like this:
ORACLE_HOME/sso/bin/ssocfg.sh http sso.mydomain.com:4443
Update the three attributes this way:
<Property NAME="HTTPMachine" VALUE="sso.mydomain.com"/>
<Property NAME="HTTPPort" VALUE="4443"/>
<Property NAME="HTTPProtocol" VALUE="HTTPS"/>
5.Save and close the file.
6.     Reload the OracleAS console:
     ORACLE_HOME/bin/emctl reload
7. Issue these two commands:
ORACLE_HOME/opmn/bin/opmnctl restartproc process-type=HTTP_Server
ORACLE_HOME/opmn/bin/opmnctl restartproc process-type=OC4J_SECURITY
Registering mod_osso
1.     This command sequence that follows shows a mod_osso instance being reregistered with the single sign-on server.
$ORACLE_HOME/sso/bin/ssoreg.sh
     -oracle_home_path $ORACLE_HOME
     -config_mod_osso TRUE
     -mod_osso_url https://myhost.mydomain.com:4443
2.     Restarting the Oracle HTTP Server
After running ssoreg, restart the Oracle HTTP Server:
ORACLE_HOME/opmn/bin/opmnctl restartproc process-type=HTTP_Server
Configuring the Single Sign-On System for Certificates
1.     Configure policy.properties with the Default Authentication Plugin
Update the DefaultAuthLevel section of the policy.properties file with the correct authentication level for certificate sign-on. This file is at ORACLE_HOME/sso/conf. Set the default authentication level to this value:
DefaultAuthLevel = MediumHighSecurity
Then, in the Authentication plugins section, pair this authentication level with the default authentication plugin:
MediumHighSecurity_AuthPlugin = oracle.security.sso.server.auth.SSOX509CertAuth
2.     Restart the Single Sign-On Middle Tier
After configuring the server, restart the middle tier:
ORACLE_HOME/opmn/bin/opmnctl restartproc process-type=HTTP_Server
ORACLE_HOME/opmn/bin/opmnctl restartproc process-type=OC4J_SECURITY
Bringing the SSO Users to OCA User Certificate Request URL
The OCA server reduces the administrative and maintenance cost of provisioning a user certificate. The OCA server achieves this by authenticating users by using OracleAS SSO server authentication. All users who have an Oracle AS SSO server account can directly get a certificate by using the OCA user interface. This reduces the time normoally requidred to provision a certificate by a certificate authority.
The URL for the SSO certificate Request is:
https://<Oracle_HTTP_host>:<oca_ssl_port>/oca/sso_oca_link
You can configure OCA to provide the user certificate request interface URL to SSO server for display whenever SSO is not using a sertificate to authenticate a user. After the OracleAS SSO server authenticates a user, it then display the OCA screen enabling that user to request a certificate.
To link the OCA server to OracleAS SSO server, use the following command:
ocactl linksso
opmnctl stoproc type=oc4j instancename=oca
opmnctl startproc type=oc4j instancename=oca
You also can use ocactl unlinksso to unlink the OCA to SSO.

I have read the SSO admin guide, and performed the steps for enabling SSL on the SSO, and followed the steps to configure mod_osso with virtual host on port 4443 as mentioned in the admin guide.
The case now is that when I call my form (which is developed by forms developer suite 10g and deployed on the forms server which is SSO enabled) , it calls the SSO module on port 7777 using http (the default behaviour).
on a URL that looks like this :
http://myhostname:7777/pls/orasso/orasso.wwsso_app_admin.ls_login?Site2pstoreToken=.......
and gives the error :
( Forbidden
You don't have permisission to access /sso/auth on this server at port 7777)
when I manually change the URL to :
https://myhostname:4443/pls/orasso/orasso.wwsso_app_admin.ls_login?Site2pstoreToken=.......
the SSO works correctly.
The question is :
How can I change this default behaviour and make it call SSO on port 4443 using https instead ?
Any ideas ?
Thanks in advance

Can I use my Macbook pro in Africa with just a adapter?

I am travelling to Africa and was wondering if I can use my macbook pro with just the adapter for 240 or do I also need the converter.

On any of your electronic equipment, look at the power adapter. For example, the adapter with my MacBook Pro says "Input: 100-240V" therefore it will work at 240 volts with only an adapter, no transformer needed.

Hey guys! I want to connect my Imac 21 " with my Tv just for fun. Does anyone know , how it works?

Selecting the correct adapter and cable depends on which year model iMac you have and what inputs the TV has?
Check the User's Guide that came with your iMac or your Spec's at > Apple - Support - Technical Specifications
to see if your iMac has a Mini-DVI or Mini DisplayPort and then select that adapter with the correct connection for the TV.
Example: if you have a 2010 or 2011 iMac and an HDMI ready TV, then you would want the > Moshi Mini DP to HDMI Adapter with Audio Support - Apple Store (U.S.)

How to use thunderbolt to gigabit ethernet adapter

hi mates. i just purchase the Thunderbolt to Gigabit Ethernet Adapter last week for my Mac Book Pro Retina. but i have no idea how it work. i tried just plug in the adapter and the LAN cable in but no luck...
Any idea how it works?

Plug in the Adapter and the cable to the adapter and the other end of the cable to a switch or router then Reboot the system. Then check the Network section in System Preferences to see if the Ethernet shows up. If it does your done. If not then you have a bad adapter, a bad cable, both bad adapter and cable or the Thunderbolt port is bad.
Or at the last a corrupted install of OS X.

Can you determine link status with USB Ethernet adapter?

I'm wanting to replace an old G4 PowerBook with a 11" MacBookAir. I install networks, and I often need to determine link status of an Ethernet connection. With the built-in Ethernet port on most Macs, you can check the Network Status to see if there is link on an Ethernet connection (either the green or yellow status signs).
If I am using the Apple USB Ethernet adapter, do I get similar feedback from the Network preference panel? If not, perhaps a terminal command that would do the same?

Yes - the Network Panel under System Preferences works the same as with a regular Mac, showing USB Ethernet status (connected, disconnected, etc) and with the updated connected IP address, etc.

How to configure channels with Spring-Flex?

Newbie here trying to get my first Flex/BlazeDS app up and running.   I'm using the Spring-Flex integration and believe I have properly configured my servet and remoting destinations. My only remaining questions relate to how to configure the channels.
The use of the Spring/BlazeDS integration means that I do not have to have a remoting-config.xml file anymore. But it the documentation is unclear as to whether I need to configure my channels within a services-config.xml file still.
If I do need a services-config.xml file (and I think I do), how does one get away without hard coding the server URL? I've seen samples on the web like:
url="https://\{server.name\}:\{server.port\}/flex2gateway/cfamfsecure"
But I don't get when/where/what does the dynamic substituion? They almost look like Maven or Spring properties, but they can't be. Is this just something that has to be manually changed after installation?
Finally, I really don't like the idea of compiling the Flex client against a server-side configuration file as I have seen suggested on the web. How would one go about have the Flex client discover - or otherwise figure out what it needs to do dynamically?
Sorry for the multi-question post....thanks for any help!

You could load that info from an XML file as described below. I took this from the doc.
To further externalize configuration, you can pass the endpoint URL value to the client at runtime. One way to do this is by reading a configuration file with an HTTPService component at application startup. The configuration file includes the information to programmatically create a channel set at runtime. You can use E4X syntax to get information from the configuration file.
The following MXML application shows this configuration file technique:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
    applicationComplete="configSrv.send()">
    <mx:Script>
    <![CDATA[
    import mx.controls.Alert;
    import mx.messaging.channels.AMFChannel;
    import mx.messaging.ChannelSet;
    import mx.rpc.events.ResultEvent;
    private var channelSet:ChannelSet;
    private function configResultHandler(event:ResultEvent):void
        var xml:XML = event.result as XML;
        var amfEndpoint:String = "" + xml..channel.(@id=="amf").@endpoint;
        if (amfEndpoint == "")
            Alert.show("amf channel not configured", "Error");
        else
            channelSet = new ChannelSet();
            var channel:AMFChannel = new AMFChannel("my-amf", amfEndpoint);
            channelSet.addChannel(channel);
            ro.channelSet = channelSet;
            ro.getProducts();
    ]]>
    </mx:Script>
    <mx:HTTPService id="configSrv" url="config.xml" resultFormat="e4x" result="configResultHandler(event)"/>
    <mx:RemoteObject id="ro" destination="product"/>
    <mx:DataGrid dataProvider="{ro.getProducts.lastResult}" width="100%" height="100%"/>
</mx:Application>
The MXML application reads the following configuration file:
<?xml version="1.0" encoding="utf-8"?>

WRT54GS CONNECTION TO MODEM THROUGH USB CABLE WITH AN ETHERNET ADAPTER

The ethernet port on my motorola surfboard modem is damaged but the usb port is fine. I am attempting to connect my WRT54GS (ver 6) router to the modem via a usb cable with a male ethernet adapter. Unfortunately it does not appear that the router is able to accept such an input due to driver or firmware issues. The modem requires me to set up my pc with another driver specifically for the usb connection when i am connected directly. Any suggestions?

Get a new modem, The USB is not meant for that it's meant for wireless network storage.

How to configure sync with my local ftp server?

I have used XMarks since now because it hallow me to synchronize my bookmarks with my local server. Now XMarks don't work anymore because it's not more possible to synchronize the passwords.
Any other alternative imposes to use an external server and I don't want to use an external server. My data must remain on my machine it's absolutely excluded that i use an external unknown server for this.
The only solution must be a free solution (a real free solution) and the firefox synchronization seems to me the best/only one.
But I've not found how to configure it to use my own server.
So how to do it, where are the options to the synchronizer to give my own ftp server or whatever other server it needs?

iAS 6.0 sp4 officially does only support iPlanet Directory Server 5.0 sp1 and 4.13.
For more details visit: http://docs.iplanet.com/docs/manuals/ias/60/sp4/ig/prep.htm#42084
I guess, you can specify the directory server during the time of installation.
Thanks,

How to configure network printer on solaris 10 intel based

how to configure the network printer in solaris 10
like hp laserjet printer/printers,

Very very easy.
Go to the print manager . (printmgr I believe or in the launch menu under preferences)
select add a network printer
Fill out the info. I find that the hpijs printer driver works better then the suggested foomatic on my hp 4000s. I could not print pdfs otherwise.
Other things to know is the protocol should be BSD (at least it works for me). And add the port to the destination so 192.168.0.1:9600 for example (for hp).
thats about it. To have it show up correctly in JDS you should probably add it to the printer list under the launch->preferences->printer preferences.
