Problem with socket gateway

I am trying to use the socket gateway to watch a port 1010
for all incoming data. When data comes in I want to log it. Well to
get started I just used a simple example from the docs to see if I
could get it to work. But when I try to start the gateway I get
this error:
SocketGateway(tvsocket) Error opening port 1010:
java.net.BindException: Address already in use: JVM_Bind
Does anyone know what that means?
jfill

It could mean just what it says. The port is already in use
by some other application. On Windows, you can verify that using
FPort.

Problem with socket packaging

There seems to be a problem with the plastic cpu clip i work as a tech in a computer store we build many systems with msi boards, the plastic clip on the 915G series most times has fallen off and pins in the cpu socket have been damaged.
You should use a plastic insert under the cpu hood to prevent it from falling off.

Quote
Not sure either why DelUK thinks this is not a suitable topic for this forum.
Probably because Del interpreted "You should use a plastic insert under the cpu hood to prevent it from falling off." to mean that "You" was MSI, and not the members of this forum. Oddly enough, I interpreted this the same way. I don't see where Del indicated the topic was not suitable, though.
As Del said, and as mentioned in the Forum Rules, MSI does not participate here. If you feel there is a manufacturing problem, contact MSI directly.

Problem with Socket Sever

Hello,
I have a problem with a java socket.
I have a server application that generate random number.
I my client application, I connected to server application and red the random number.
My problem is in my application client only read one time. After this, the socket server application close.
How to do the server socket wait a new request from my client application?

Put your accept in a while ....
while (!this.interrupted()) {
Socket socket;
try {
socket = serverSocket.accept();

Problem with RD gateway manager

Hi,
Have some problems with manager. It used to work, but suddenly I can't connect to local server.
Get this error:
"The RD Gateway Managment snap-in console cannot connect to the server. To connect to this server, you must be a memeber of the local administrators group on the server."
The user account that i'm using is a member of the local administrator group.
Any ideas?
The RDS server is a Win2012 server. The AD server is a win 2008 R2 server.
Thanks
\Kent

Hi Kent,
Thanks for your comment.
For this you need to create RD Rap and RD CAP policies. When you create the RD RAP, add the user groups that you defined in the RD CAP. Also, create a new RD Gateway-managed computer group that contains both the NetBIOS names and the fully qualified domain
names (FQDNs) of the RD Session Host servers or the RD Session Host server farm that hosts the RemoteApp programs.
Please check below article for information.

Hope it helps!
Thanks.

Codec problem with one gateway

I am having a very strange problem with one of my gateways. No matter how I set up my regions and device pools I continue to have all calls go through this gateway as G729. This would be fine except that I can't do conference calls because of codec mismatches.
The gateway is a PRI running H323. CM 3.2.2(c) Gateway is a 3640 running 12.2.11(t)
All regions are currently set to G711.
I read something about a command under voice-port that sets the default codec. What I don't understand is, if this is what is causing it to go to G729, why is this the only gateway that ignores the regions.
Any help would be appreciated.

Cisco VoIP gateways support the codec negotiation feature. This feature provides the ability for a Cisco VoIP gateway to connect to other VoIP devices without necessarily knowing which codec is used for a call-setup. Also, this feature allows Cisco VoIP gateways to dynamically adjust to changes on remote devices. As long as the codec used by the remote VoIP device matches the capabilities-list of the Cisco VoIP gateway, the VoIP call is completed.
The following example shows how to configure codec negotiation:
Cisco-router# config t
Cisco-router(config)# voice class codec 1
!--- This sets up class 1 to be assigned to the dial peer.
Cisco-router(config-class)#codec preference 1 g723r63
Cisco-router(config-class)#codec preference 2 g729ar8
Cisco-router(config-class)#codec preference 3 g711ulaw
Cisco-router(config-class)#codec preference 4 g726r32 bytes 240
!--- These commands define the preferred codec list using 1,2,3, and 4 to set the preference.
Cisco-router(config)#dial-peer voice 1 voip
Cisco-router(config-dial-peer)#voice-class codec 1
!--- This assigns voice-class codec 1 to the dial-peer
Cisco-router(config-dial-peer)#destination-pattern 4723155
Cisco-router(config-dial-peer)#session target ipv4:192.168.100.1

Problem with Mobile Gateway 1.0 Configuration

reffering to the config guide for mobile gateway 1.0 (https://websmp102.sap-ag.de/~sapdownload/011000358700000518422009E/Config_Guide_MGW_SP01_rev.pdf) we are facing some problems with the configuration in the DOE.
In Chapter 4.1.1.4 a SWCV "MAS_SMARTPHONE" is mentioned, which is not available in our System, though all other steps before have been successfully executed.
We are on SP08 and SWCV "SAP BASIS 7.10" is activated and generated.
Does anyone know a workaround?

Problem with socket cross domain

Hi guys,
This is my cross domain file:
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "/xml/dtds/cross-domain-policy.dtd">

<cross-domain-policy>
<site-control permitted-cross-domain-policies="*"/>
<allow-access-from domain="localhost" to-ports="80" />
</cross-domain-policy>
I am placing it in my server.
From flex i am running this:
Security.loadPolicyFile("my server address");
And yet I am getting this event:
SecurityErrorEvent type="securityError" bubbles=false cancelable=false eventPhase=2 text="Error #2048"
What can I do?

Hello ILikeMyScreenNameNdCoffee,
I had the same problem with XMLSocket and I used a policy server that runs
on the remote server on port 843 and from Flex I load file before connecting
the xmlsocket Security.loadPolicyFile("my server address:843"). If you want
I can upload a version of my policy server or you can use the server policy
from here

Problem with socket permissions!

Hi All!
I'm developing an applet that displays an image after downlading it from a server; this server is different from the server I download the applet from, so I have problems with security. In fact I get the following exception:
java.security.AccessControlException: access denied (java.net.SocketPermission 172.16.1.22:8080 connect,resolve)
I'm using:
- Java Plugin 1.3;
- Netscape 7.0;
- IE 6;
I've tried to self-sign the applet but with no results (maybe I cannot use selfsigned certificate with java plugin 1.3);
After that I've created a new policy file ("MyPolicy" file)and mentioned it into:
C:\Program Files\JavaSoft\JRE\1.3.1_03\lib\security\java.policy
but it didn't resolve my problem (maybe I'm doing something wrong in creating my policy file??!!).
Which steps do I have to follow in order to make my applet connect to images server without security problems?
Thanks so much in advance,
Carlo

1.     Compile the applet
2.     Create a JAR file
3.     Generate Keys
4.     Sign the JAR file
5.     Export the Public Key Certificate
6.     Import the Certificate as a Trusted Certificate
7.     Create the policy file
8.     Run the applet
Susan
Susan bundles the applet executable in a JAR file, signs the JAR file, and exports the public key certificate.
1.     Compile the Applet
In her working directory, Susan uses the javac command to compile the SignedAppletDemo.java class. The output from the javac command is the SignedAppletDemo.class.
javac SignedAppletDemo.java
2.     Make a JAR File
Susan then makes the compiled SignedAppletDemo.class file into a JAR file. The -cvf option to the jar command creates a new archive (c), using verbose mode (v), and specifies the archive file name (f). The archive file name is SignedApplet.jar.
jar cvf SignedApplet.jar SignedAppletDemo.class
3.     Generate Keys
Susan creates a keystore database named susanstore that has an entry for a newly generated public and private key pair with the public key in a certificate. A JAR file is signed with the private key of the creator of the JAR file and the signature is verified by the recipient of the JAR file with the public key in the pair. The certificate is a statement from the owner of the private key that the public key in the pair has a particular value so the person using the public key can be assured the public key is authentic. Public and private keys must already exist in the keystore database before jarsigner can be used to sign or verify the signature on a JAR file.
In her working directory, Susan creates a keystore database and generates the keys:
keytool -genkey -alias signFiles -keystore susanstore -keypass kpi135 -dname "cn=jones" -storepass ab987c
This keytool -genkey command invocation generates a key pair that is identified by the alias signFiles. Subsequent keytool command invocations use this alias and the key password (-keypass kpi135) to access the private key in the generated pair.
The generated key pair is stored in a keystore database called susanstore (-keystore susanstore) in the current directory, and accessed with the susanstore password (-storepass ab987c).
The -dname "cn=jones" option specifies an X.500 Distinguished Name with a commonName (cn) value. X.500 Distinguished Names identify entities for X.509 certificates.
You can view all keytool options and parameters by typing:
keytool -help
4.     Sign the JAR File
JAR Signer is a command line tool for signing and verifying the signature on JAR files. In her working directory, Susan uses jarsigner to make a signed copy of the SignedApplet.jar file.
jarsigner -keystore susanstore -storepass ab987c -keypass kpi135 -signedjar SSignedApplet.jar SignedApplet.jar signFiles
The -storepass ab987c and -keystore susanstore options specify the keystore database and password where the private key for signing the JAR file is stored. The -keypass kpi135 option is the password to the private key, SSignedApplet.jar is the name of the signed JAR file, and signFiles is the alias to the private key. jarsigner extracts the certificate from the keystore whose entry is signFiles and attaches it to the generated signature of the signed JAR file.
5.     Export the Public Key Certificate
The public key certificate is sent with the JAR file to the whoever is going to use the applet. That person uses the certificate to authenticate the signature on the JAR file. To send a certificate, you have to first export it.
The -storepass ab987c and -keystore susanstore options specify the keystore database and password where the private key for signing the JAR file is stored. The -keypass kpi135 option is the password to the private key, SSignedApplet.jar is the name of the signed JAR file, and signFiles is the alias to the private key. jarsigner extracts the certificate from the keystore whose entry is signFiles and attaches it to the generated signature of the signed JAR file.
5: Export the Public Key Certificate
The public key certificate is sent with the JAR file to the whoever is going to use the applet. That person uses the certificate to authenticate the signature on the JAR file. To send a certificate, you have to first export it.
In her working directory, Susan uses keytool to copy the certificate from susanstore to a file named SusanJones.cer as follows:
keytool -export -keystore susanstore -storepass ab987c -alias signFiles -file SusanJones.cer
Ray
Ray receives the JAR file from Susan, imports the certificate, creates a policy file granting the applet access, and runs the applet.
6.     Import Certificate as a Trusted Certificate
Ray has received SSignedApplet.jar and SusanJones.cer from Susan. He puts them in his home directory. Ray must now create a keystore database (raystore) and import the certificate into it. Ray uses keytool in his home directory /home/ray to import the certificate:
keytool -import -alias susan -file SusanJones.cer -keystore raystore -storepass abcdefgh
7.     Create the Policy File
The policy file grants the SSignedApplet.jar file signed by the alias susan permission to create newfile (and no other file) in the user's home directory.
Ray creates the policy file in his home directory using either policytool or an ASCII editor.
keystore "/home/ray/raystore";
// A sample policy file that lets a JavaTM program
// create newfile in user's home directory
// Satya N Dodda
grant SignedBy "susan"
     permission java.security.AllPermission;
8.     Run the Applet in Applet Viewer
Applet Viewer connects to the HTML documents and resources specified in the call to appletviewer, and displays the applet in its own window. To run the example, Ray copies the signed JAR file and HTML file to /home/aURL/public_html and invokes Applet viewer from his home directory as follows:
Html code :
</body>
</html>
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
width="600" height="400" align="middle"
codebase="http://java.sun.com/products/plugin/1.3/jinstall-13-win32.cab#Version=1,3,1,2">
<PARAM NAME="code" VALUE="SignedAppletDemo.class">
<PARAM NAME="archive" VALUE="SSignedApplet.jar">
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.3">
</OBJECT>
</body>
</html>
appletviewer -J-Djava.security.policy=Write.jp
http://aURL.com/SignedApplet.html
Note: Type everything on one line and put a space after Write.jp
The -J-Djava.security.policy=Write.jp option tells Applet Viewer to run the applet referenced in the SignedApplet.html file with the Write.jp policy file.
Note: The Policy file can be stored on a server and specified in the appletviewer invocation as a URL.
9.     Run the Applet in Browser
Download JRE 1.3 from Javasoft

Trouble with socket gateway and an as3 xmlsocket connection

I succesfully set up the socket gateway and am able to conect to the CF socket gateway and send data from flash to the gateway.
The error I keep getting is when I add return value to the "onIncomingMessage"... cf error always logs "Cannot send outgoing message. OriginatorID "123124124" is not a valid socket id.
I am passing the originatorID as in the docs.... my question is what is a valid originatorID?
<cffunction name="onIncomingMessage" output="no">
<cfargument name="CFEvent" type="struct" required="yes">


   <cfset message="#CFEvent.Data.message#">
   
   <cfset orig="#CFEvent.OriginatorID#">
<cfset retValue = structNew()>
<cfset retValue.OriginatorID = orig>
<cfset retValue.MESSAGE = message>

<cfreturn retValue>
</cffunction>
I really hope I can get an answer hardly any docs or anything online on how to correctly return a message via a socket gateway.
Thank you.

Problem with socket and Threads

Hi,
I have coded a package that sends an sms via a gateway.
Here is what is happening:
* I create a singleton of my SMSModule.
* I create an sms object.
* I put the object in a Queue.
* I start a new Thread in my sms module that reads sms from queue.
* I connect to sms gateway.
* I send the sms.
* I disconnect from socket! This is where things go wrong and I get the following error (see below).
I have a zip file with the code so if you have time to take a look at it I would appreciate it.
Anyway all hints are appreciated!

Hi,
I'm trying to build a chat server in Java on Linux OS.I've created basically 2 classes in the client program.The first one shows the login window.When we enter the Login ID & password & click on the ok button,the data is sent to the server for verification.If the login is true,the second class is invoked,which displays the messenger window.This class again access the server
for collecting the IDs of the online persons.But this statement which reads from the server causes an exception in the program.If we invoke the second class independently(ie not from 1st class) then there is no problem & the required data is read from the server.Can anyone please help me in getting this program right.I'm working on a p4 machine with JDK1.4.

You're connecting to the server twice. After you've successfully logged in, pass the Socket to the Messenger class.
public class Messenger {
    Socket connect;
    public static void main(String args[]) {
        Messenger mes = new Messenger(args[0]);
    Messenger(Socket s, String strg) {

Problem with socket responses with flex

Hi, I am using the code below to connect to an IMAP server.
When I telnet to the server and use the commands that I am sending in the code, the rsponses are correct.
However, when I run the code below, I only obtain the ready and logged in responses as shown below.
Any ideas why I am not receiving the full set of responses from the socket?
Thanks in advance fro your advice.
The following is the output from the code:
+++++++++++++++++ START SENDING IMAP DATA +++++++++++++++++++++++++
sent: . login user1 myPassword
sent: . status INBOX (messages)
sent: . select INBOX
+++++++++++++++++ END SENDING IMAP DATA +++++++++++++++++++++++++
++++++++ [IMAP START]
Response is: * OK Dovecot ready.
[IMAP END] +++++++++
++++++++ [IMAP START]
Response is: . OK Logged in.
[IMAP END] +++++++++
The code is:

When I run telnet, the console responses are the same as the tcpdump messages.
When I run the program, the messages from tcpdump match the messages in my trace statements.
The messages from telnet and running the program are different:-)
I can only assume (at the moment) that I am sending multiple messages too quickly(?), but I did a quick and dirty big "for loop" to slow down the sending of subsequent messages, but with no resulting change in the programs behaviour.
So, still thinking about the problem - unfortunately.

Problem with socket programming(Vista)

I'm not sure if this has something to do with windows vista.
I wrote simple echo client and server programs and the client program contains these lines
String hostname="172.16.54.22"; //My comp's IP
int portNo=6666;
mySocket=new Socket(hostname, portNo);
Now the problem is that the client program is able to communicate with the server only when I run both of them in xp machines or if I run the server in vista and client in xp. The client is not able to connect to the server when both the client and server are running in a vista machine or if the server is running in xp and client in vista.
It'd be nice if any of you could throw some light on this issue.
PS:
It doesn't work even if I turn the firewall off
The programs work well when I give hostname="localhost" or hostname="127.0.0.1"
Here are my programs

Sorry everyone but I'd been giving a wong IP address thinking it's my own. The problem's solved.
Thanks for the response Peter.

Problem with Socket Client - Intermittent Truncated Response in AIX

{color:#0000ff}Hi guru
I have written on Socket Client method below to send request byte[] to Host and receive response byte[] from Host.
For this particular response, I'm expecting Host to return me byte[] with length 2274.
My problem is intermittently I received truncated message byte[] from Host with length only 1392. Sometimes I received full 2274 message, sometimes I received 1392 length. I tested in continual of 10 times by sending the same request to host, intermittently received truncated response message.
My real problem is that this only happened in {color:#ff0000}AIX {color}machine. With the same class, I tested on {color:#ff0000}Windows {color}platform and i received full response message byte[] with 2274 lenght always. Therefore, im counting out the possibilities that Host might send me truncated message.
Can anyone pls help to tell me how should I proceed to troubleshoot this problem in AIX? Is possible for me to trace what coming in?
{color}
public byte[] sendToHost(byte[] requestMessage, String requestId, String localTxnCode) throws Exception {
BufferedInputStream bis = null;
BufferedOutputStream bos = null;
long startTime = 0;
long elapsed = 0;
try {
LogManager.log(LogManager.DEBUG, Constants.DEFAULT_LOGGER_NAME, requestId, "[" + localTxnCode + "] To connect and send message to Host hostAddr=[" + hostAddr + "], hostPort=[" + hostPort

bos.write(requestMessage);
bos.flush();

if (bis != null) {
bis.close();

bos = null;
} catch (Exception e) {
LogManager.log(LogManager.ERROR, Constants.DEFAULT_LOGGER_NAME, requestId, "ARBConnection.sendToHost() [" + localTxnCode + "] Exception during closing BufferedInputStream and BufferedOutputStream");

I tried to use DataInputStream.readFully(byte[]). However, I could not retrieve a single byte from Host. It won't return until it fills the buffer, or EOS occurs. Isn't that what you wanted?
You need to believe it here. Either the sending application or Java or the sending TCP stack or the intervening routers or the receiving TCP stack or Java or the receiver can break up the transmission into 1 byte reads and there is nothing you can do about it at the receiver except what I said. BufferedInputStream will mask the effect to some extent but you still have to code under that assumption. You don't have any choice about this.
