Can't connect to remote host via Channel Adaptor

[Jean]

i setup a gateway based on the jpos gateway tutorial (http://jpos.org/doc/tutorials/jpos-gateway.pdf).

here is my 10_channel.xml:

<channel-adaptor name='jpos-channel' class="org.jpos.q2.iso.ChannelAdaptor" logger="Q2">

<channel class="org.jpos.iso.channel.NCCChannel"

packager="org.jpos.iso.packager.ISO87BPackager"

header="6000190002">

     <property name="host" value="123.164.14.90" />

     <property name="port" value="11000" />

</channel>

<in>jpos-send</in>

<out>jpos-receive</out>

<reconnect-delay>10000</reconnect-delay>

</channel-adaptor>

But, i can't connect to the remote and the log is as following:
<log realm="org.jpos.transaction.TransactionManager" at="2022-09-15T23:38:22.175426" lifespan="1010ms">

But when I change the host Ip to a NCCC stimulation server on localhost or when i send the message direct to the "remote host" via jPos Channel (the code is below) , everything works fine and i receice the response from remote host.

I wonder what i'm wrong in config the 10_channel.xml, 
Pls help me

Do you have access to 123.164.14.90:11000 ?

Have you tried a simple 'telnet 123.164.14.90 11000' ?

[Jean]

i did. i  have the response when i call it directly with the client app as following: 

public static void main(String[] args) throws IOException, ISOException {

ISO87BPackager packager = new ISO87BPackager();

String hostName = "123.164.14.90:11000";

int portNumber = 11000;

NCCChannel channel = new NCCChannel(hostName, portNumber, packager,ISOUtil.hex2byte("6000190002"));

channel.setTimeout(30000);

Date now = new Date();

ISOMsg m = new ISOMsg();

m.setMTI("0800");

m.set("3", "900000");

m.set("11", "000043");

m.set("12", "144042");

m.set("13","0315");

m.set("24","019");

m.set("41","00000122");

m.set("42","000000080210002");

m.recalcBitMap();

logISOMsg(m);

channel.connect();

channel.send(m);

ISOMsg response = channel.receive();

System.out.println("********** Response***********");

logISOMsg(response);

}

private static void logISOMsg(ISOMsg msg) {

System.out.println("----ISO MESSAGE to Pack-----");

try {

System.out.println(" MTI : " + msg.getMTI());

for (int i = 0; i <= msg.getMaxField(); i++) {

if (msg.hasField(i)) {

System.out.println(" Field-" + i + " : " + msg.getString(i));

}

}

} catch (ISOException e) {

e.printStackTrace();

} finally {

System.out.println("--------------------");

}

}

No header, different String for host.

I suggest you ask the targe what they see in each case or trace your side of the network and see what is and what isnt leaving your machine and compare.

Thank you for supporting me. 
i found the problem. That because the bank didn't return the STAN for logon message so jpos couldn;t mapping the request and response message.
And we tried to mapping by another field like Terminal ID , and everything worked perfectly
