  • Windows 2003 routing by port

    - by vansickle
    I have remote Windows 2003 server with two network interfaces e.g. Cn1 and Cn2. I need that all traffic goes through Cn1 except for one port (for me it's 3389, rdp for administration) that works over Cn2. Currently when I setup all connections work through Cn1, I completely lose connection over Cn2 - and can't connect to server via RDP over Cn2. Now I used static routing based on my ip address (which can changed - so it's bad).

  • Server access through switch port

    - by Kblz Btz
    I am using wireshark to monitor traffic on a server - Problem is, the computer I am using is only a terminal wired through the switch. Main line comes into the server which is relayed to multi-port switch (roughly 50 connections). Right now I get a lot of server communication between my it and my terminal but shows no information for other terminals. Can wireshark be configured to monitor ALL traffic in this environment?

  • Configuring correct port for Oozie (invoking PIG script) in Cloudera Hue

    - by user2985324
    I am new to CDH4 Oozie workflow editor. While trying to invoke a pig script from Oozie workflow editor, i am getting the following error. HadoopAccessorException: E0900: Jobtracker [mymachine:8032] not allowed, not in Oozies whitelist It looks like Oozie is submitting the job to Yarn port (8032). I want it to submit to 8021 (MR jobtracker) port. Can someone help me in identify where to set the job tracker URL or port so that oozie picks up the correct one (using Hue or Cloudera manager). Previously I tried the following but none of them helped Modfied workflow.xml file /user/hue/oozie/workspaces/../workflow.xml file. However it gets overwritten when I submit the job from workflow editor. In cloudera Manager -- oozie -- configuration --Oozie Server (advanced) -- Oozie Server Configuration Safety Valve for oozie-site.xml property I set the following- <property> <name>oozie.service.HadoopAccessorService.nameNode.whitelist</name> <value>mymachine:8020</value> oozie.service.HadoopAccessorService.jobTracker.whitelist mymachine:8021 and restarted the oozie service. 3. Tried to override 'jobTracker' property while configuring the pig task. This appears as follows in the workflow file however it doesn't take effect (or doesn't override) and still uses 8032 port. <global> <configuration> <property> <name>jobTracker</name> <value>mymachine:8021</value> </property> </configuration> </global> I am using CDH4 version. Thanks for looking into my question.

  • Configuring IHS server to direct traffic to the Netty component bound to a port

    - by rbot
    I have a Server Component ( based on Jboss-Netty, which could maintain & handle persistent connections ) deployed in WAS. This component when deployed & initiated within the WAS environment, binds to a port & listens for incoming HTTP connection. [ Why i had to deploy a Netty HTTP Server within WAS is another story - management requirement !! Netty is deployed in WAS as a spring bean which when initiated runs on a port in the machine, independent of WAS ] Clients (mobile app) were able to establish persistent HTTP connections (to the above URL::Port) with this netty component & send/receive requests. Now, I have to replicate this feature in our Production Environment where a IHS Server (Web Server) which sits before the WAS. What i expected is to get a IHS URL which could redirect the incoming packets to the specific PORT on WAS, so that the Client apps can establish a similar persistent http connection. Our Server Admin tried a few combinations and we are not able to identify how to proceed further on this. Your expert ideas would be highly appreciated.

  • how to recieve text sms to specific port..

    - by Umesh
    recieve text sms to specific port.. I have been looking for an answer to this question but but to no avail. This question has been popped a few times but nobody seems to have a clear answer. my code is as follows.. --MANIFEST FILE-- <receiver android:name=".SMSRecieve" android:enabled="true" <intent-filter <action android:name="android.intent.action.DATA_SMS_RECEIVED"/ <data android:scheme="sms" / <data android:host="localhost" / <data android:port="15005" / </intent-filter </receiver --SMS sending method-- String messageText = msgTxt.getText().toString(); short SMS_PORT = 15005; SmsManager smsManager = SmsManager.getDefault(); smsManager.sendDataMessage("5556", null, SMS_PORT, messageText.getBytes(), null, null); --Broadcast Reciever code-- static final String ACTION = "android.intent.action.DATA_SMS_RECEIVED"; //static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";(tried this too, but failed) if (intent.getAction().equals(SMSNotifyExample.ACTION)) { ...do some work.. } I also tried to replace android:name to "android.provider.Telephony.SMS_RECEIVED" but the result is the same. my application does not recieve the SMS on the specified port. Once i remove the following line its works fine <data android:scheme="sms" / <data android:host="localhost" / <data android:port="15005" / could you suggest me what am i missing??

  • Process-to-port mapping with SNMP and/or wmi/wmic in java

    - by Niddy888
    I'm trying to use SNMP to map outgoing ports on my host computer with the application running on the computer that is responsible for that communication. When running "netstat -ano" I get access to Protocol, Local Address (with port), Foreign Address (with port), State and PID. But I want to do this entirely without having to execute "cmd" from Java. By using SNMP OID: .1.3.6.1.2.1.25.4 (.iso.org.dod.internet.mgmt.mib-2.host.hrSWRun) I get access to PID (ex. 1704), Name (ex. cmd.exe), Path (ex. C:\Windows\system32) among others. There is an SNMP OID: .1.3.6.1.2.1.6.13 (.iso.org.dod.internet.mgmt.mib-2.tcp.tcpConnTable) that give you access to TCP connection state, local address, local port, remote address, remote port. But NO PID. So to sum up. My question again: Is there a way to "map" these tables together? Either directly in SNMP with other OID's or in conjunction with WMI / WMIC?

  • Expected output from an RM-1501 RS232 interface?

    - by Jon Cage
    I have an old RM-1501 digital tachometer which I'm using to try to identify the speed of an object. According to the manual I should be able to read the data over a serial link. Unfortunately, I don't appear to be able to get any sensible output from the device (never gives a valid speed). I think it might be a signalling problem because disconnecting the CTS line starts to get some data through.. Has anyone ever developed anything for one of these / had any success?

    Hi, I'am runing locally service on port 81 (192.168.1.101) I would like to access server from outside MY.WAN.IP.ADDR:81.

  • ssms cannot connect to default sql server instance without specifying port number

    - by Oliver
    I have multiple SQL Server 2005 instances on a box. From SSMS on my desktop I can connect to that box's named instances with no problem. After some recent network configuration changes, when I want to connect to the default instance from SSMS on my desktop, I have to specify the port number. Before the network changes, I did not have to specify the port number of the default instance. If I remote to any other box (including the one in question), and use that box's SSMS to connect to that default instance, success. From my desktop, and only from my desktop, I have to specify the port number. Is it a SQL Server configuration that I've missed? Is it possible something in my PC's configuration is getting in the way? Where would I look, or what could I pass on to the network folks to help them resolve this? Any help is appreciated.

  • LF/CR issue with RS232 in Linux

    - by Albinoswordfish
    I've been having this problem where anytime I send a 0xA through an RS-232 in a Linux OS the receiver interprets that as 2 bytes, 0xD and 0xA. Also whenever I receive 0xD the serial port interprets that as 0xA. I've been reading that there are known issues regarding this, has anybody been able to find a solution?

  • Add / remove a port number to/from a URL with REGEX in PHP

    - by SuperDuck
    Hello guys, I've searched but was unable to find an existing regex function. Has anybody done this before? I wish to add a port number, or remove a potantially existing one from a url in php. To use in some functions which translate a given url to the secure one, unsecure one, etc. Now I need a second SSL secured site on the server so I need to dynamically add a port number while converting http to https, and remove any port number while converting from https to http. Thanks, Duck

  • TcpListener.Start() does not open the port

    - by SoMoS
    Hello, I have a class that inherits from the TcpListener, this class Shadows the Start method just to call the base Start() and the base BeginAcceptTcpClient(). From time to time the method is called but the port is not opened (netstat does not show the port open). The class looks like this Public Class ExtendedTcpListener Inherits System.Net.Sockets.TcpListener Public Shadows Sub Start() SyncLock (m_stopLock) MyBase.Start() MyBase.BeginAcceptTcpClient(AddressOf Me.CompleteAcceptTcpClient, Me) My.Application.Log.WriteEntry("Extended Tcp Listener started ...", TraceEventType.Verbose) End SyncLock End Sub Any idea on what's happening or how to debug the issue? As the Start() is called without exception I expected to find the port always opened (the log is always written). Extra information: when the Start method works fine it works each time until app is restarted. When the Start method does not work it won't work again until the app is restarted.

  • Non ASCII char in PHP?

    - by domagoj412
    Hello, I am trying to send something to serial port (r232) with PHP. I am using this class: http://www.phpclasses.org/browse/package/3679.html The problem is that I am allowed to send only 1 byte. But if I send something like "1", I am actually sending 49 (ASCII for 1). Instead of send("1"), I tried with send(1) but it is no good, because this is integer which has 2 bytes. So is there a way to send a "real" char, not ASCII equivalent?

  • What are the licence restrictions for the RxTx Library

    - by Azder
    I want to make an Application that uses RxTx version 2.2pre2 to work with Serial Ports. What are the Licence restrictions, since it is an "LGPL v 2.1 + Linking Over Controlled Interface" licenced library if I don't use the Sun's javax.comm.* interface, but the RxTx's own gnu.io.* when importing into Java Files?

  • windows server 2008 r2 - can't get apache to run on port 80

    - by Robbiegod
    I have a rackspace cloud server running windows server 2008 r2. I've uninstalled IIS because I want to install Apache. I've installed Apache but it fails everytime i try to run it when i listen to port 80. I've run the command netstat -aon|finderstr "80" and i see the following: C:\Users\Administratornetstat -aon|findstr "80" TCP 0.0.0.0:80 0.0.0.0:0 LISTENING 4 TCP 10.180.15.249:139 0.0.0.0:0 LISTENING 4 TCP [::]:80 [::]:0 LISTENING 4 UDP 10.180.15.249:137 : 4 UDP 10.180.15.249:138 : 4 So what are these things running on port 80 and why can't i get apache to start? Is there an alternative port for to run apache under that will work just as well as 80?

  • Ubuntu 8.04 LTS MySQL port remote access

    - by Stig Christian
    Hi! I have tried everything I know, but still no solution to this problem. MySQL works perfectly on localhost, but it seems port 3306 is blocked from the outside... I have commented out "bind-address" in /etc/mysql/my.cnf, and there is no iptables rules that deny this port. (I have even opened the port in iptables just to be sure) Still I can`t connect to the server from a remote connection (telnet or portscan returns negative results). Where is the problem?

  • How to stop listening on an HTTP::Daemon port in Perl

    - by Trevor
    I have a basic perl HTTP server using HTTP::Daemon. When I stop and start the script, it appears that the port is still being listened on and I get an error message saying that my HTTP::Daemon instance is undefined. If I try to start the script about a minute after it has stopped, it works fine and can bind to the port again. Is there any way to stop listening on the port when the program terminates instead of having to wait for it to timeout? use HTTP::Daemon; use HTTP::Status; my $d = new HTTP::Daemon(LocalAddr => 'localhost', LocalPort => 8000); while (my $c = $d->accept) { while (my $r = $c->get_request) { $c->send_error(RC_FORBIDDEN) } $c->close; undef($c); }

  • Is 0x9B (155decimal) a special control character? Why is it missing from ascii tables?

    - by Chris
    Hi, I'm working on an embedded system, and i'm having dramas getting it to send a certain chunk of data across the serial port. I narrowed it down and found that if a 0x9B is present in the message, it corrupts the message. So i then look up 0x9b (155) on http://www.asciitable.com/, and it's missing! Isn't that a bizarre coincidence! Any ideas, is this a special character or something?

  • What is wrong with this attempt of sending a break-signal?

    - by Jook
    I have quite a headache about this seemingly easy task: send a break signal to my device, like the wxTerm (or any similar Terminal application) does. This signal has to be 125ms long, according to my tests and the devices specification. It should result in a specific response, but what I get is a longer response than expected, and the transmitted date is false. e.g.: what it should respond 08 00 81 00 00 01 07 00 what it does respond 08 01 0A 0C 10 40 40 07 00 7F What really boggles me is, that after I have used wxTerm to look at my available com-ports (without connecting or sending anything), my code starts to work! I can send then as many breaks as I like, I get my response right from then on. I have to reset my PC in order to try it again. What the heck is going on here?! Here is my code for a reset through a break-signal: minicom_client(boost::asio::io_service& io_service, unsigned int baud, const string& device) : active_(true), io_service_(io_service), serialPort(io_service, device) { if (!serialPort.is_open()) { cerr << "Failed to open serial port\n"; return; } boost::asio::serial_port_base::flow_control FLOW( boost::asio::serial_port_base::flow_control::hardware ); boost::asio::serial_port_base::baud_rate baud_option(baud); serialPort.set_option(FLOW); serialPort.set_option(baud_option); read_start(); std::cout << SetCommBreak(serialPort.native_handle()) << std::endl; std::cout << GetLastError() << std::endl; boost::posix_time::ptime mst1 = boost::posix_time::microsec_clock::local_time(); boost::this_thread::sleep(boost::posix_time::millisec(125)); boost::posix_time::ptime mst2 = boost::posix_time::microsec_clock::local_time(); std::cout << ClearCommBreak(serialPort.native_handle()) << std::endl; std::cout << GetLastError() << std::endl; boost::posix_time::time_duration msdiff = mst2 - mst1; std::cout << msdiff.total_milliseconds() << std::endl; } Edit: It was only necessary to look at the combo-box selection of com-ports of wxTerm - no active connection was needed to be established in order to make my code work. I am guessing, that there is some sort of initialisation missing, which is done, when wxTerm is creating the list for the serial-port combo-box.

  • Java: How to clear socket bindings

    - by Matt1776
    I am having a few issues with sockets within my Java SIP client. When I bind to an address and port, if something goes wrong I have to attempt to reconnect, usually after I've stopped and restarted the process. Problem with that is then the port is bound and I am forced to increment the local port. How can I remove the binding to the port I am targeting before binding to it? If that isnt possible, then how can I trap the process just before it ends so that I can locate the socket binding and close it manually?
