Getting remote address in applet

hi guys,
how to get client ip in an applet.i tried lot with each n every
possible combination
but it always gives u Localhost/127.0.0.1.
first i tried with this line of code...
clientIP=InetAddress.getLocalHost().getHostAddress();
then i tried with this one........
String hostname = InetAddress.getLocalHost().getHostName();
System.out.println(hostname);
InetAddress[] ads = InetAddress.getAllByName(hostname);
for (int i=0; i<ads.length; i++) {
System.out.println(ads);
then i tried with javascript calling applet function in javascritp
but all in vain.
why is it so. is there any security problem in applet.
or what?? or where i m worng??
anyone know how to get client ip.
it will be greatfull if any of u cud tell me the solution.
thankx in advance

Get remote address in HttpSessionAttributeListener?

Hi,
I'm using an HttpSessionAttributeListener to log user sessions: it looks for the "NtlmHttpAuth" attribute, which is bound by the NtlmHttpFilter from the jCIFS project.
Is there a way to get the remote user address, from the HttpSession? I can't seem to find an obvious way to do it. The only thing that comes to mind is to create another filter (executed before NtlmHttpFilter) that would grab it from the request and set it as an attribute on the session, but this seems a little circuitous. I'm not even sure it would work, since I'm not 100% clear on how exactly NtlmHttpFilter interacts with the session life-cycle.
What's the right thing to do?

The remote address is indeed request based, not session based.

Problem in getting remote address?

Hi,
I have a procedure on my login page, which reads user's IP address and stores it in a log file. I am using the following statement to get the IP address of remote user:
select owa_util.get_cgi_env('REMOTE_ADDR') from dual;
It is running fine on my workspace at http://apex.oracle.com and returns the real IP address of the remote user. But when I use the same code at my hosted server I get 127.0.0.1 instead of real IP.
Any ideas please?
Thanks,
Zahid

Hello,

Can you please explain that how it can be misleading and how would you go for securing anything super confidential etc.?

Well, lots of reasons really. Firstly the IP address that you think identifies an end user might in fact be the IP address of a transparent proxy server that their ISP uses (a transparent proxy server can modify the request headers to change the IP address so that the request appears to come from them rather than the end user). The user might also have actively used a proxy server to 'appear' to be coming from somewhere else (a common technique to view content that should not be visible outside certain countries etc).
The user might be inside a corporate LAN which presents a single (or multiple) NAT IP address to the world, so you only know the IP address of their main NAT routers/switches etc.
The user might be using a tunneled SSH session so that the traffic appears to be coming from another bastion host rather than their own machine.
The user might be using a network like TOR, so that their network traffic appears to be coming from elsewhere.
Pretty much since TCP/IP became popular there have been ways and means to spoof your IP address (for various nefarious reasons), it's always been relatively easy to spoof a fake IP address at the packet level...obviously the difficult bit is to then receive the content if you're pretending to be elsewhere ;) How it has and continues to be done...
Those are just a few examples off the top of my head, there are others...
My point is, that using the IP address of the HTTP request can be useful, however just be aware that the address might not be the actual real address of the real end user (for the reasons described). I have actually seen people block a particular IP address from access a web site, only to find that it was actually the address of a proxy server used by hundreds (or more likely thousands) of other users who had also been inadvertently blocked from accessing the site.
Hope this helps,
John.

Please help: Get IP address of a remote device (wifi kit) from DHCP router

Hi ppl,
I am about to get the IP address for the wifi kit which is connected to the same router with my PC.
I need to control my wifi kit through TCP client communication, but DHCP tends to assign new IP address to my wifi kit when connected to router.
Hence, i wish to write a java function to trace the IP address before starts the communication.
I am thinking to get the wifi kit's IP address based on the Hostname (name of the wifi shield):
As below:
InetAddress thatIp = InetAddress.getByName("Wiznet");
System.out.println("IP E:"+thatIp.getHostAddress());
But i don't think this is secure..
I attempt to research for getting IP address with MAC..
But have ambiguity on the result i found.
It stating i have to get the ARP table from router but it is not a good approach.
I have no luck for next finding on how retrieving the table with Java.
Hereby hope to have your advise how can i get the ip address of my wifi kit in a more dynamic and secure method..
is it using Hostname or MAC address or else...
many thanks.

hi... wish to have your advise again.
I tried to retrieve the arp table in java and attempt to extract the IP address based on MAC address for particular devise.
But i stuck with the substring... my code is as below:
Process result = Runtime.getRuntime().exec("arp -a");
     BufferedReader output = new BufferedReader
               (new InputStreamReader(result.getInputStream()));
     String line = output.readLine();
     while(line != null){
          if ( line.startsWith("default") == true ){
               System.out.println("is default");
               break;
     line = output.readLine();
     String ipAdd = line.substring(0, 18);
     String MACAdd = line.substring(24, 42);
     System.out.println(line.length() + " " + line + " " + ipAdd + " " + MACAdd );
i m trying to sub the IP and MAC accordingly.. but i got error saying
Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 42
     at java.lang.String.substring(Unknown Source)
     at ExecTest.main(ExecTest.java:22)
i dun understand this! as since the length of LINE is 56 , why STRING INDEX OUT OF RANGE happen?!
please advise!!!

Hi Paul,
Try using the RFC_READ_TABLE function module...
Pass the table name as t001w which contains the plant details.
Hope this helps.

Hi
I have installed coheI have installed coherence server "fmw_12.1.3.0.0_coherence_Disk1_1of1.zip" along with Examples on windows machine and C++ client coherence-cpp-12.1.3.0.0b51709-windows-x86-vs2012.zip on the same machine.
I have built the "contacts" C++ Example successfully and while I execute this "contacts" using run I am facing TcpAcceptor error.
On my coherence server the TcpAcceptor is listening on port 8088, so I have modified the extend-cache-config.xml file with values "ip address of my windows machine" and port as "8088".
All the time I am getting below error,

Problem in connecting remote server using Applet?

Hello everybody,
I am facing problem in connecting to remote server using Applet in browser. I am using JDK 1.5.0_12 and running the application on apache 2.2.
Firstly I have tried with simple jar file which could not connect to remote server and throws permission denied than now I am trying with signed jar file but also not working. I have changed the java.policy file of JDK in server with grant all Permission but also it throws "java.security.AccessControlException:access denied(java.net.SocketPermission 127.0.0.1:1521 connect, resolve)".
Can anybody suggest me how to solve this problem?
Thank You.

VWLC clients getting DHCP address from management VLAN

Hi,
We have a strange scenario whereby some wireless employees are obtaining addresses from the management VLAN.
Some details:
DHCP managed by MS DHCP 2008 R2 (in remote data centre)
Cisco vWLC AIR-CTVM-K9 running v7.6.110.0
AP's are a mix of 2602 and 3702 (46 and 2 of each respectively)
SSID's are employee, guest, and production devices (all mapped to their own interface with relevant VLAN tag as per normal)
AP's all in FlexConnect mode as per vWLC caveats
Some employees are receiving addresses in the wireless management VLAN. This network only has six DHCP addresses available as it is solely for AP's, WLC and HSRP gateway. Obviously this gets exhausted very quickly leaving us with a scenario where clients are not obtaining DHCP addresses.
I understand that with FlexConnect mode, it will assign IP's from the native VLAN. What I don't understand is why most clients receive addresses in the correct VLAN, but a handful do not, and then cannot get an address from DHCP. Obviously the ideal scenario would be to put the AP's into local mode but unless this has changed in a SW release then I don't believe it's possible...
My question is: How do I get ALL the employees to obtain addresses from their interface and not the management VLAN?
Thanks in advance.

Hi,
I think we need a closer look to your configurarion to eliminate some possibilities:
- What is the WLAN security you choose?
- What is the interface that is configured under the WLAN?
- Does your WLAN have local switching enabled?
- If your security is using RADIUS server, do you have AAA override enabled under the WLAN config?
- If your security is using RADIUS server, do you send any attributes to the users?
- You have eliminate that clients that got management vlan IPs are always on same AP or they can be on any AP.

Ip remote address invalid

Hey Guys, trying to connect with a friend of mine for the first time today, neither of us has used iChat before. He is on Leopard, i'm on Tiger.
We can text no problem, but we can't video or audio chat.
Keep getting the message IP Remote Address Invalid.
We tried the usual, logging off etc, even reverted to our mobile broadband sticks & still no-go.
Any ideas????

OK so heres the thing, he has a macbook & an iMac - both new, both running leopard, & he can connect those via, text, vid & audio
But he cant connect to me, running Tiger, so it appears the fault is with me.
My router is a Thompson 735BB6
I'm on version 3.1.9 (v446)

OWSM Custom Step - Determine Remote Address

I'm working on a custom step that provides custom metrics for some of our web services (BPEL). The only thing that I haven't been able to figure out is the remote address.
The heart of my code is:
public IResult execute(IMessageContext messageContext) throws Fault {
Result result = new Result();
result.setStatus(IResult.FAILED);
boolean isRequest = (IMessageContext.STAGE_REQUEST.equals(messageContext.getProcessingStage()) || IMessageContext.STAGE_PREREQUEST.equals(messageContext.getProcessingStage()));
if (!isRequest) {
result.setStatus(IResult.SUCCEEDED);
return result;
try {
log(messageContext);
result.setStatus(IResult.SUCCEEDED);
} catch (Exception ex) {
messageContext.getInvocationStatus().setErrorMessage(ex.getMessage());
generateFault(ex.getMessage());
return result;
private void log(IMessageContext messageContext) throws Exception {
String client = null;
try {
client = ((MessageContext) messageContext).getRemoteAddr();
// HttpServletRequest httpServletRequest = (HttpServletRequest) messageContext.getProperty("javax.servlet.request");
// if (httpServletRequest != null) {
// client = httpServletRequest.getHeader("Host");
} catch (Exception ex) {
String msg = "Unable to extract the client IP address.";
throw new Exception (msg);
<continue capturing metrics and log to the database>
The problem is, client is always null. I've tried both techniques I've found online and neither of them seem to produce any results. Could there be some server configuration that is preventing this information from be sent to OWSM?

mrmora,
After opening a Service Request and communicating with one of Oracle's reps, I was told that the HttpServletRequest (and I guess other client info) is never available for either the Server Agent or Client Agent.
I created a Gateway, instead, and and I'm now getting the HttpServletRequest and the client's IP. Both of these codes now work:
HttpServletRequest request = (HttpServletRequest)messageContext.getProperty("javax.servlet.request");
String clientIP = httpSrvltRqst.getRemoteHost();
=====
String clientIP = ((MessageContext)messageContext).getRemoteAddr();
Thanks.

Is it possible to get Remote Desktop to work from my Surface 2 to a local PC running Vista?

Is it possible to get Remote Desktop to work from my Surface 2 to a local PC running Vista?
I keep getting "cannot find PC" entering IP or PC name
but as a test I have set up my PC to do web hosting, and I can browse to the IP address using desktop IE and see my local web pages.
I've just found a reference that says it has to be Business Vista.
Why would Microsoft put such a STUPID restriction in?
I think this Surface thing is going to go back if so.
What about Win8 64 Pro? Will that work?

Hi,
Thank you for posting in Windows Server Forum.
Yeah, windows 8 pro can connect to surface 2. There is detailed article guide for it, please check below link.

Login "async" Remote Address

Hi,
we have ACS 5.3 and I don't know why we have a lot of authentication failed of of Username like:
"state to down"
"d state to up"
"% Authentication failed"
"l1/0:15, changed state to up"
All logs have "async" in the Remote Address field
The followng is an example of the log:
Do you know why?
thank you
Fabrizio

can you please tell me what device they are coming from? The async port is a console port. Once you find the NAS ip address,please get it physically checked what is connected on Console port, even if we have a console cable connected remove it. It seems like there is something that is causing a noise on console port (tty0).
On the NAS device, please use "show line" and check if there is noise appearing on the console port.
