• How to connect two databases on two servers

  How to connect two databases on two servers. For example
  a serevr is in India and another in Australia.
  The following example is correct or not
  
  Select A.ID, B.Name [10.50.17.87] .HR. EMP A, [192.168.100.125] .HR. TRANS B

• Copy users and hashes of password between two servers that does not use AD

  Hello

  We have two servers running Windows 2008 R2, but because we run AD on two of them, I need to find a way to copy the users to the users group to the other server remote desktop and duplicate the hashes thus.

  Any ideas? No user file or parameter must copy.

  It is better that I do not have need to install AD on one of them and only for the purpose of copying users and hashes

• Connectivity between two piles of Dell 2048

  Hi guys, I'm very new to the configuration of the switches. We have a small office and just implement a new data room. We have 4 switches of POE Dell 2048 x stacked for VOIP and PCs phones and 2 x Dell 2048 switches stacked to our servers. I have 4 x 10 gb twinax cables to connect the two heaps as in the pic below:

  

  What is the best way to implement these four connections? I tried to do a SHIFT of four ports in each stack, and it seemed to fall some ping until I disabled STP for the LAG group. I'm a little worried about turning off STP however. These are the only switches that are on the network. Any ideas on what the best config for this would be appreciated. Sorry, as I said I am quite new to this.

  Thanks, Dave

  Hi guys,.

  Just to wrap this I configured LACP on the mentioned LAG today and now, she purrs like a kitten.

  See you soon,.

• Catalyst 3560 liaison network between two servers ubuntu 12.04

  Hello world

  I'm trying to transfer data with more than 1 Gbit/s between two servers, but I just get a card (approximately 1 Gbps) NETWORK performance. Here is my configuration:

  srvnettest1 and srvnettest2 are two 12.04 servers ubuntu with three network cards in each. management eth0, eth1 and eth2 are network cards that should work as a team. ;-) Here are the relevant parts of fit it:

  My test tools are nuttcp (by transfer) and bmon (to watch what is happening during the transfer). Unfortunately, I am not able to transfer more than 1 Gbps:

  I tried a lot of things, but now I have no idea what to do or what to try next. It is true that I have no deep understanding of Cisco etherchannels yet, so I guess that my mistake is somewhere in the IOS configuration.

  Thanks a lot for your support and welcome to Germany

  Stephan

  Hello Stephan,

  With EtherChannels, a single flow (the flow of images/packages with the same source and destination) is always carried by a single link only. Implementation of Cisco implements not balancing on connections in an EtherChannel load by package, and it avoids a reason: executives could get reorganized, something this plain Ethernet never should do. This means that you will not see an improvement in bandwidth on the speed of a single link to your EtherChannel for a single stream. It is only the overall bandwidth for several stream which increases. The advantage of EtherChannel becomes therefore obvious that if your server starts many conversations and several stream handling.

• Setting up authentication with two servers (not redundant) authentication

  What I'm trying to do is to test a new authentication server, while disturbing is not the service for the current server already in place.

  I would like to test remote access to the network.

  Currently, I use a 5510 ASA that is configured to use a server RSA for authentication.

  I want to configure ASA to also use a RADIUS server for another form of authentication, without impact on the current RSA authentication.

  I found this topic which deals with something similar:

  https://supportforums.Cisco.com/discussion/10849371/two-RADIUS-server-1-...

  but it seems to imply that you can only configure two servers if they use two different protocols, so I think that this would not work in my case?

  Could someone clarify if what I want to do is possible?

  Hello

  You need to change the configuration for remote users.

  You can create another tunnel-group as well as political group and for this tunnel-group, you can use the newly created servers RADIUS group.

  tunnel-group Test-new type remote access
  tunnel-group Test-new general-attributes
  vpn address pool
  Group- Radius-new group authentication server

  authorization-server-group Radius-new group
  accounting-server-group Radius-new group
  default-"new-policy-created" group policy

  When users connect to this tunnel-group, they will be authenticated and authorized against "RADIUS-news-group.

  I hope this helps!

  Kind regards

• Connection to multiple servers through smartview

  Currently, my users side by comparison of the coast between the HFM application on Production servers and development then. To do this, they create a report in every environment, but I wonder; is there anyway to create a report to connect the two? Each environment has its own APS so I'm a little confused on if this is even possible. Even if I change the name of the connection, it does not. They use the reporting for this function, Ad-Hoc could be used?

  System: v11.1.2.1 (if it works with Smart View 11.1.2.3, then I'm ready to upgrade).

  That's right, you can recover data from both at the same time.  You'd have a column where you pull in your Production data and another column where you pull in your data of development within the same Excel sheet.  Again, it is using HsGetValue, not ad hoc reports.  Maybe it's different for you, but for me, I'd go under private connections - create a new connection - select my Dev server from the menu drop-down or enter-it's to see a list of all applications on the dev server, select the application that you want to connect to, give it a name and then use that name in your formula (for example HsGetValue ("Dev" etc...).  In your other coulumn would connect you to the production in a similar way, but your forumula would be HsGetValue("Prod",etc...).

• Failed to get vCenter to keep in touch with the two servers virtual virtual ESXi 4.0.

  I have a laboratory setup where I have two servers virtual windows (Domian controller and vCenter) and two virtual servers ESXi 4.0, on a Dell sitting bare metal Server ESXi 4.0.  So basically four virtual servers on a server phyiscal.  I can't get the vCenter server to stay connected to the ESXi 4.0 servers.  We'll always stay connected, and the other will be disconnected.  When I try to reconnect to the disconnected from vCenter Server I get a connection failure.  If I go directly to the ESXi box (the one that I can't connect to vCenter well) I can connect correctly by using the identification information same accurate I use however vCenter.  I'm running while mode track except metal nu ESXi installation that has the free license installed on it.  This is a limitation of the performance of the software in trial mode.  I hope not that would be nice to do for study purposes and to show the customers in a sort of demo of the installation.  Can anyone help plese here?  It is a laboratory configuration I do to perform vMotion, so I practice for my VCP.  Thanks in advance.

• Try to set up a direct parallel connection between two computers in Windows XP Home edition

  I tried to set up a direct parallel connection between two computers in Windows XP. I have the right cable (CAT 5 Ethernet connection) and you can set up the connection on my own laptop, but when I go through the installer on another laptop it create new connection-establishment of advanced connection--> when the next window opens asking me to choose between "accept incoming connections" and "connect directly to another computer" (which I need to select) for the second option is grayed out and not can not be selected.

  The same thing happens when I try to implement the same connection between my laptop and the desktop we have. All of these computers are running on Windows XP service pack 2. I really need help with this because I'm about to start pulling my hair.

• Can damage the FPGA module if I connect accidentally two pins writing together.

  My current configuration has a PXI chassis with two FPGA modules.  Each FPGA module has an adaptation Module 6581 on that.  I would like to test the signal through my system path by having the user to move some cables that would be a reason for a return to the other looping FPGA.

  I fear, however, the risk of the user is not correctly as shown and somehow a channel available in writing that connects to another channel write-enabled.  This damage to the FPGA or adaptation modules?

  Hi Brian,.

  Your concerns are correct. We never want to connect two pins that are output voltage. If two pins are outputs digital mistakenly connecting them together may damage one or both nodes in output since there is nowhere to flow the potential.

  It is well to connect to two pins that read a voltage. If both pins running entry digital (reading of the pins), as there is no risk, nor pin would be likely to be damaged.
