How to make 2 clients on same VLAN communicate to each other when tunnel-loop-prevention is enabled?

Requirement:
How to make two clients on same VLAN communicate to each other when tunnel-loop-prevention is enabled on tunneled-node configuration at controller?
Whenever we enable tunnel-loop-prevention on controller while we configure tunneled-node, the communication between two tunneled-node client on same VLAN is blocked or dropped.
If the tunneled-node clients are of different VLANs then they can communicate between them even when the tunnel-loop-prevention is enabled on the controller.
Solution:
To make two tunneled-node client on same VLAN to communicate between them, we need to enable "local-proxy-arp" for the interface VLAN on the controller.
Once it is enabled now the tunneled-node clients on same VLAN can communicate between each other.
Configuration:
To enable "local-proxy-arp":
Get to the interface of the VLAN on the controller
Example :
(config)#interface vlan 5
(config)#ip local-proxy-arp
To enable tunnel loop prevention on controller
(config)# tunnel-loop-prevention
Verification
Show commands:
To check if tunnel-loop-prevention is enabled or disabled
#show tunneled-node config
Tunnelded node Server: Enabled
Tunnel Loop Prevention: Enabled
To check if local-proxy-ap is enabled:
#show interface vlan 5
Look for in the output "ProxyARP enable"

Unknown HostOK, I'm no socket programming expert; but I can see a few potential problems with what you've written.
1. First off, which line is line 88? Line numbers would be useful. Also, indenting your code properly would make it easier to read.
2. Your 'while(!str.equalsIgnoreCase("close"))' will always fail with a NullPointerException because 'str' is initially set to null.
3. Your 'while(true)' loop worries me. How does it exit? Relying on an exception is usually very bad practise.
4. You are not handling SecurityExceptions. While it's unlikely to happen on your machine; it could easily happen on another.
5. It might be worth indicating the actual exception thrown in your "Failed to accept client" message. accept() can throw three different types of IOException.
6. All the threads you create will be called "New THREAD", which doesn't provide much value.

How to make your iPad and iPhone commicate with each other

How to make your iPad and iPhone commicate with each other

this is very easy...
firstly disconnect the DSL modem for the linksys..
then connect the computer to the linksys router (port 1/2/3/4)..
then access the linksys setup UI
open ur web browser
site: http://192.198.1.1/
username: [blank]
password: admin
now hook up the westell modem.. and goto the status page ...
check Internet IP.
if then Internet IP is 192.168.1.* then,
disconnect the westell from the router and goto the setup page.
change the LOCAL IP address to 192.168.2.1 (notice the 2.1 and not 1.1)
save settings....
connect the westell and viola ur online...
if the Internet IP is 0.0.0.0 then
goto the setup page and change the 'Internet connection Type' to 'PPPoE'
once done the page changes and give u a place to enter a username and a password.. this username and password is given by verizon..
sud be something like '[email protected]'
once done save settings...
goto the status page and hit connect... give it a few moments... u shud get a Internet ip address... if u get one ur online if not then power cycle the entire network. and try check to see if u get an ip..
hope this helps...
cheers..
Life is short... So get movin !!!

How do I enable two wireless clients to communicate with each other?

I have a WRT54GL with the latest firmware. I have two computers which are both connected to the router, with IP addresses assigned via DHCP. Neither has a firewall running. I cannot get them to communicate with each other -- even ping doesn't work. I can ping the router itself using the IP address assigned to it on the WAN side by my ISP. Both computers have no problem reaching the internet through the router.
What settings on the router will enable the communication to occur? I can't find anything in the router's user interface which appears to control this.
Thanks.
Solved!

How to make client application

hi....
help me...^ ^ how to make client application(not standalone..)
I seached bea document.. but I can't it.
if someone have sample(.ear or .jar), I hope you it share...

Hi
Client Application can be any Java class, JSP etc which is a part of multi
tier architecture which accepts input from Client and directs request to the
middle tier for processing. You can refer to
http://e-docs.bea.com/wls/docs61/jsp/index.html
for building jsp's as Client application.

How can I have threads communicate with each other?

I'm working on a project that requires a group of classes communicating with each other. I decided on using a server and carrying out communication that way. However, my app only has communication between the client and server. I need the clients to be able to communicate with each other. Does anyone know how I can do this or point me to a good tutorial?

Sorry, here's a bone stock example of my server and client:
<SERVER>
package testserver;
import java.io.*;
import java.net.*;
import java.util.*;
public class TestServer
static int portOpen;
public static void main(String[] args)
portOpen=4000;
try
ServerSocket portListener = new ServerSocket(portOpen);
TestServer userThreads = new TestServer();
while (1==1)
Socket userConnection=portListener.accept();
userThreads.new PortConnection(userConnection);
catch (Exception e)
System.out.println("The server encountered a serious error. Server shut down.");
e.printStackTrace();
System.exit(0);
class PortConnection extends Thread
//Declare variables to handle connections.
Socket ourConnection;
BufferedReader serverInput;
PrintWriter serverOutput;
PortConnection(Socket userConnection)
try
ourConnection=userConnection;
serverInput=new BufferedReader(new InputStreamReader(userConnection.getInputStream()));
serverOutput=new PrintWriter(userConnection.getOutputStream(),true);
start();
catch (Exception e)
System.out.println("An error occurred when a user attempted a connection.");
public void run()
serverOutput.println("Welcome to the Server.");
try
serverOutput.close();
serverInput.close();
ourConnection.close();
catch (Exception e)
</SERVER>
<CLIENT>
package testclient;
import java.io.*;
import java.util.*;
import java.net.*;
public class TestClient {
static BufferedReader userInput;
static Socket quizServer;
static BufferedReader serverInput;
static PrintWriter serverOutput;
static String serverData;
public static void main(String[] args) {
userInput = new BufferedReader(new InputStreamReader(System.in));
try {
quizServer=new Socket("localhost",4000);
catch (Exception e) {}
try
serverInput=new BufferedReader(new InputStreamReader(quizServer.getInputStream()));
serverOutput=new PrintWriter(quizServer.getOutputStream(),true);
catch (Exception e) {}
try {
serverData=serverInput.readLine();
catch (Exception e) {}
System.out.println(serverData);

Log into each device with your own Apple ID's in Settings > iCloud.
Then, so you can share preiously purchased apps, log into both devices using the Apple ID used to make those purchases, but ONLY in Settings > iTunes and Apps Stores.
Verify that each device uses your own Apple IDs in Settings > Facetime and Settings > Messages.

How many midlets can communicate to each other?

Hi
How many midlets can communicate to each other? Also can we use one midlet as a library for another midlet?
thnx.

I mean to say how they can use each other's resources? Is it possible thet one midlet can use other midlets resource? Also can we add or delete the midlet from our application .jar file within the same midlet?

Hi user 1724, before icloud, we had the same issue....
so yes, the solution was to each log into the mac separately.
i kept the main itunes library and apple id, and my son made his own itunes library (which linked to the main itunes/apple id) - so we were able to maintain separate contacts lists.
but then w/ the cloud i guess we assumed the cloud would know we each have different contact lists on diff. phones, but it seems the cloud just lumped it all together -

2 J2EE RI servers which communicate with each other

Hi all,
I'm wondering whether the following scenario is possible, and if so, of course I would like to now how I have to achieve it.
I want to run two j2ee ri application servers on two different machines. What I want, is that the applications on the two different servers can communicate with each other.
Any help on this will be greatly appreciated.

Greetings,
that does the lookup, so I have the bean clasees in
the classpath of the project (is that what you
ment?).In addition to the bean classes, the client needs the stub files generated by deploytool - the reason for the ClassCastException is due to that the cast actually gets made against the server stub(s) which, in this case, isn't available to the client. The stubs are generated during deployment and have the same name as your interfaces with the suffix '_impl' (implementation). The first dialog of the deployment wizard has the option to "Return client jar" - select it (a checkbox) and add the resulting jar file (has the same name as your .ear file with the ending 'Client.jar'), to your client's CLASSPATH (just mount it as a filesystem in Forte4J ;). This file has the stubs along with the rest of your bean's associated classes.
Can you help? I'm realy stuck.I hope this helps.
Thanks.

Can I have two LANs with the same IP route to each other

Hi there,
I have a customer who has a televantage voip network on a private 192.68.0.0/24 network but has two sites connected via a wireless tower that wants to enable QOS over between the two sites by using a 2621XM router at each end. I've enabled QOS on both routers for voice and video but haven't deployed this yet since I'm not sure if I need to change one of the sites networks to a different network number since I'll have the routes in place with a 192.168.1.0 on the WAN side. If both remote networks stay with the same number scheme of 192.168.0.0/24 will they be able to find each other when requesting where a remote 192.168.0.0 host is or do I need to change of the offices networks to a 192.168.2.0 network to make this work? Sounds kind of basic but before deploying I wanted to get some input...thanks.

Routers cannot route unless the address blocks for each interface are different.
If you have two sites connected by any kind of link, and you'll use one site as a gateay to the Internet, then you'll need at least four different addresses/ blocks:
The 'b' site LAN, i.e., fa/0/0:192.168.0.0/24
The 'b' site WAN (interconnecting link), i.e., fa0/1: 192.168.1.1/30
The 'a' site WAN (interconnecting link), i.e., fa0/1:192.168.1.2/30
The 'a' side LAN, i.e., fa0/0:192.168.2.0/24
(assumes that your wireless link is acting as a bridge or non-routing link) - the fa0/1 device connects to the wireless devices).
If you use the same router on the 'a' side for the interconnecting link for both the 'a' LAN and the Internet gateway, then the third interface would be your Internet WAN address.
The 'b' side LAN interface is your 'b' side default gateway for you clients
The 'a' side LAN interface is the 'a' side default gateway for your clients
Set a default gateway on the 'a' router to the ISPs Default gateway / next hop address.
If you're using a third router for an Internet gateway, then the LAN interface address becomes the default gateway for the clients on that LAN, and you'll need to set up a static route pointing to the other LAN in the routers that connect the two LANs..
A routing protocol may be useful but, depending on your actual bandwidth available, it's probably better to just set up static routes (no routing protocol bandwidth utilization).
The /30 for the WAN link gives some economy of address usage, but it may also secure the link better, since there are no additional addresses for the intruder to use; they'd have to spoof one of the two valid addresses (.1 & .2) as well as crack your encryption (and / or other security).
There's an armload of other possible configurations / topologies / address schemes, I believe this one would be reasonably common.
The bottom line is that a router can only route from one address block to another. In order to pass traffic between two segments with the same address block, you need a bridge / switch, or some other layer one/two device (like a wireless transceiver pair).
Good Luck

Migration between two environments which can't communicate with each other

My customer is intending to do migration from test environment to production environment using CCM.
But the two environments are not in the same network.
The environments' setting is as blew.
BO TEST Repository can communicate with Web BO Server.
BO PRODUCTION Repository (Cluster environment) can communicate with Web BO Server.
BO TEST Repository and BO PRODUCTION Repository (Cluster environment) are in the different network, they can't communicate with each other.
Setting Target Repository manually in CCM.
Questions are:
1. In CCM, as long as both Source Repository and Target Repository can communicate with Web BO Server, the migration will be successful.
Is that right?
2. If 1 is not right, is there additional setting should I do?
For example, If I need to open some firewall port?
3. Is there other attentions should I notice?
Thanks

Yes that is correct
2. If 1 is not right, is there additional setting should I do?
For example, If I need to open some firewall port?
You have another option which is to use the BIAR files. Export your objects to a BIAR file in source environment, and import them from BIAR into the target environment
3. Is there other attentions should I notice?
when using BIAR files as solution, Make sure that you keep them < 1GB size to avoid corruption
you may have to increase or adjust timeouts on input and output repository servers as well

Remote Access VPN users unable to communicate with each other

Hi,
We have configured Remote Access VPN on Cisco IOS router. Users are able to access the inside resources but cant communicate to each other. Any suggestions on the issue?

Have you excluded the VPN traffic from being NATed when traffic is going between clients?
Please post a full sanitised configuration of the router so we can check it for configuration issues.

Is there a way to have 2 threads communicate w/each other?

I'm working on a program which requires 2 threads to communicate with each other. I was wondering how I can do this? How can I find out an id to reference a thread?

I am not sure that there is .. not directly anyway. You can creat an intermediate class and pass copies of its objects to your threads. And then your threads can use it as a means of communication between them. For example:
class A {
// you have some private and public methods here.. which you can use to communicate between threads
class B extends Thread {
private A aVar;
public B (A a) {
aVar = a;
//you have your run method here..
class C extends Thread {
private A aVar;
public C (A a) {
aVar = a;
//you have your run method here..
class D {
public static void main(String [] args) {
A a = new ();
B b = new B (a);
C c = new C(a);
b.start();
c.start();
}

How can i get my items to stay in place and not cross over each other when readjusting the browser s

How can i get my items to stay in place and not cross over each other when readjusting the browser size.
Basically on my site when i go from a small screen to a big screen everything doesn't adjust to the screen size. I don't know what im missing

Thanks in advance

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.
