  • How to whitelist a domain while blocking forgeries using that domain?

    - by QuantumMechanic
    How do you deal with the case of: wanting to whitelist a domain so that emails from it won't get eaten, but not having emails forged to appear to be from that domain get bogusly whitelisted whitelist_from_recvd looks promising, but then you have to know at least the TLD of every host that could send you mail from that domain. Often RandomBigCompany.com will outsource email to one or more sending companies (like Constant Contact and the like) in addition to using servers that reverse-resolve to something in its own domain. But it looks like whitelist_from_recvd can only map to one sending server pattern so that would be problematic. Is there a way to say something like "if email is from domain X, subtract N points from the spam score"? The idea would be that if the mail is legit, that -N will all but guarantee it isn't considered spam. But if it is spam, hopefully all the other failed tests will render it spam even with the -N being included.

  • How does a client find the port number of a server?

    - by Jonathan
    Hello all, I am currently learning about basic networking in java. I have been playing around with the server and client relationship between two of my computers. However, I cannot figure out how distributed programs (say, a videogame), can not only find the 'host' computer, but also the port number on which the server is running in order to create a Socket between the two computers. The only way I really see to create a Socket is with an already known IP Address, and with a known port number. How do you search a LAN network for another computer (host) searching for clients? How do you determine what port the server is located on without 'pinging' all available ports for a response (which, I understand, is bad form... Something about 'server attack'...)? In such a situation as a video game, there can be any number of computers on the same network, and any number of them might be attempting to host, or otherwise running the application. Any other important information, or perhaps reference to a more detailed tutorial than the one I am using, regarding making connections on so very little information on the client side would be appreciated. Many thanks, Jonathan

  • How can I obtain the local TCP port and IP Address of my client program?

    - by Dr Dork
    Hello! I'm prepping for a simple work project and am trying to familiarize myself with the basics of socket programming in a Unix dev environment. At this point, I have some basic server side code and client side code setup to communicate. Currently, my client code successfully connects to the server code and the server code sends it a test message, then both quit out. Perfect! That's exactly what I wanted to accomplish. Now I'm playing around with the functions used to obtain info about the two environments (server and client). I'd like to obtain the local IP address and dynamically assigned TCP port of the client. The function I've found to do this is getsockname()... //setup the socket if ((sockfd = socket(p->ai_family, p->ai_socktype, p->ai_protocol)) == -1) { perror("client: socket"); continue; } //Retrieve the locally-bound name of the specified socket and store it in the sockaddr structure sa_len = sizeof(sa); getsock_check = getsockname(sockfd,(struct sockaddr *)&sa,(socklen_t *)&sa_len) ; if (getsock_check== -1) { perror("getsockname"); exit(1); } printf("Local IP address is: %s\n", inet_ntoa(sa.sin_addr)); printf("Local port is: %d\n", (int) ntohs(sa.sin_port)); but the output is always zero... Local IP address is: 0.0.0.0 Local port is: 0 does anyone see anything I might be or am definitely doing wrong? Thanks so much in advance for all your help!

  • Issue with blocking the UI during a onchange request - prevents other event from firing.

    - by jfrobishow
    I am having issues with jQuery blockUI plugins and firing two events that are (I think, unless I am loosing it) unrelated. Basically I have textboxes with onchange events bound to them. The event is responsible for blocking the UI, doing the ajax call and on success unblocking the UI. The ajax is saving the text in memory. The other control is a button with on onclick event which also block the UI, fire an ajax request saving what's in memory to the database and on success unblock the UI. Both of these work fine separately. The issue arise when I trigger the onchange by clicking on the button. Then only the onchange is fired and the onclick is ignored. I can change the text in the checkbox, click on the link and IF jQuery.blockUI() is present the onchange alone is fired and the save is never called. If I remove the blockUI both function are called. Here's a fully working example where you can see the issue. Please note the setTimeout are there when I was trying to simulate the ajax delay but the issue is happening without it. <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script src="http://github.com/malsup/blockui/raw/master/jquery.blockUI.js?v2.31"></script> <script> function doSomething(){ $.blockUI(); alert("doing something"); //setTimeout(function(){ $.unblockUI(); //},500); } function save(){ $.blockUI(); //setTimeout(function(){ alert("saving"); $.unblockUI(); //}, 1000); } </script> </head> <body> <input type="text" onchange="doSomething();"> <a href="#" onclick="save()">save</a> </body> </html>

  • Stream Music and Video Over the Internet with Windows Media Player 12

    - by DigitalGeekery
    A new feature in Windows Media Player 12, which is included with Windows 7, is being able to stream media over the web to other Windows 7 computers.  Today we will take a look at how to set it up and what you need to begin. Note: You will need to perform this process on each computer that you want to use. What You’ll Need Two computers running Windows 7 Home Premium, Professional, or Ultimate. The host, or home computer that you will be streaming the media from, cannot be on a public network or part of domain. Windows Live ID UPnP or Port Forwarding enabled on your home router Media files added to your Windows Media Player library Windows Live ID Sign up online for a Windows Live ID if you do not already have one. See the link below for a link to Windows Live.   Configuring the Windows 7 Computers Open Windows Media Player and go to the library section. Click on Stream and then “Allow Internet access to home media.”   The Internet Home Media Access pop up window will prompt you to link your Windows Live ID to a user account. Click “Link an online ID.” If you haven’t already installed the Windows Live ID Sign-In Assistant, you will be taken to Microsoft’s website and prompted to download it. Once you have completed the Windows Live download assistant install, you will see Windows Live ID online provider appear in the “Link Online IDs” window. Click on “Link Online ID.” Next, you’ll be prompted for a Windows Live ID and password. Enter your Windows Live ID and password and click “Sign In.” A pop up window will notify you that you have successfully allowed Internet access to home media. Now, you will have to repeat the exact same configuration on the 2nd Windows 7 computer. Once you have completed the same configuration on your 2nd computer, you might also need to configure your home router for port forwarding. If your router supports UPnP, you may not need to manually forward any ports on your router. So, this would be a good time to test your connection. Go to a nearby hotspot, or perhaps a neighbor’s house, and test to see if you can stream your media. If not, you’ll need to manually forward the ports. You can always choose to forward the ports anyway, just in case. Note: We tested on a Linksys WRT54GL router, which supports UPnP, and found we still needed to manually forward the ports. Finding the ports to forward on the router Open Windows Media Player and make sure you are in Library view. Click on “Stream” on the top menu, and select “Allow Internet access to home media.”   On the “Internet Home Media Access” window, click on “Diagnose connections.” The “Internet Streaming Diagnostic Tool” will pop up. Click on “Port forwarding information” near the bottom.   On the “Port Forwarding Information” window you will find both the Internal and External Port numbers you will need to forward on your router. The Internal port number should always be 10245. The external number will be different depending on your computer. Microsoft also recommends forwarding port 443. Configuring the Router Next, you’ll need to configure Port Forwarding on your home router. We will show you the steps for a Linksys WRT54GL router, however, the steps for port forwarding will vary from router to router. On the Linksys configuration page, click on the Administration Tab along the top, click the “Applications & Gaming Tab, and then the “Port Range Forward” tab below it. Under “Application,” type in a name. It can be any name you choose. In both the “Start” and “End” boxes, type the port number. Enter the IP address of your home computer in the IP address column. Click the check box under “Enable.” Do this for both the internal and external port numbers and port 443. When finished, click the “Save Settings” button. Note: It’s highly recommended that you configure your home computer with a static IP address When you’re ready to play your media over the Internet, open up Windows Media Player and look for your host computer and username listed under “Other Libraries.” Click on it expand the list to see your media libraries. Choose a library and a file to play. Now you can enjoy your streaming media over the Internet. Conclusion We found media streaming over the Internet to work fairly well. However, we did see a loss of quality with streaming video. Also, Recorded TV .wtv and dvr-ms files did not play at all. Check out our previous article to see how to stream media share and stream media between Windows 7 computers on your home network.

  • How can I use Linksys WPSM54G print server as a bridge for another machine AND also share the printe

    - by user26453
    I have a Linksys WPMS54G currently sharing a printer via the USB port with the rest of my network via the wireless. Is there any way to set it up so that the ethernet port is bridged over the wireless adapter portion? i.e., be able to uplink another machine or switch into the network via the WPMS54G's ethernet port? Update: The network architecture is as follows: (1) Linksys WRT54G router that serves as a router, DHCP server, and wireless access point for the network. Fairly standard configuration (3) Laptops that are used throughout the house via wifi (1) Linksys WPSM54G printer server that connects via wireless to the router, in a separate room with a printer attached to print seerver's USB port along with (1) Un-networked desktop in the same room Since the printer is plugged into the USB port of the WPSM54G, I am wondering if I can connect the desktop to the ethernet port of the WPSM54G and have it bridged over the wifi to the router. The twist here is that the ethernet is initially used to connect the wireless print server to the router (for configuration, can't configure it wirelessly if you are initially on a encrypted network). Now instead of using that ethernet port as a way to connect the print server to the network (via the router), I want to use the ethernet port as a way to connect another computer to the network, in effect bridging into the router via the print server, while still sharing the printer (attached via USB) through the print server. If this is not clear, please comment. To be clear, the computer I want to connect/bridge into the network does not have a wireless card, is far from the router, and I do not want to lay ethernet cable to connect it. While I could certainly buy a legitimate wireless bridge to accomplish this, I figured since the print server already has an ethernet port, see if I can't use that.

  • tcp connect hangs on SYN_SENT if something listens, gets CONN_REFUSED if nothing listens

    - by Amos Shapira
    I'm hitting a very strange problem - when I try to connect to one of our servers the client hangs with SYN_SENT if something listens on the port (e.g. Apache on port 80, sshd on port 22 or SMTP on port 25) but if I try to connect to a port on which nothing listens then I immediately get a "CONNECTION refused" error. Connecting to other applications (e.g. rsyncd on some arbitrary port) succeeds. I ran tcpdump on the server and see that the SYN packets arrive to it but it only sends a response if nothing listens on that port. e.g.: on the server I run: # tcpdump -nn port 81 06:49:34.641080 IP 10.x.y.z.49829 server.81: S 3966400723:3966400723(0) win 12320 06:49:34.641118 IP server.81 x.y.z.49829: R 0:0(0) ack 3966400724 win 0 But if I listen on this port, e.g. with nc -4lvvv 81 & Then the output of tcpdump is: 06:44:31.063614 IP x.y.z.45954 server.81: S 3493682313:3493682313(0) win 12320 (and repeats until I stop it) The server is CentOS 5, the client is Ubuntu 11.04, the connection is done between two LAN's over per-user TCP OpenVPN. Connection to other servers on that network do not have a problem. Connecting from the other servers on the same network to that server works fine. Connections from other clients in our office over openvpn is also not a problem. What am I missing? Thanks.

  • How to limit reverse SSH tunelling ports?

    - by funktku
    We have a public server which accepts SSH connections from multiple clients behind firewalls. Each of these clients create a Reverse SSH tunnel by using the ssh -R command from their web servers at port 80 to our public server. The destination port(at the client side) of the Reverse SSH Tunnel is 80 and the source port(at public server side) depends on the user. We are planning on maintaining a map of port addresses for each user. For example, client A would tunnel their web server at port 80 to our port 8000; client B from 80 to 8001; client C from 80 to 8002. Client A: ssh -R 8000:internal.webserver:80 clienta@publicserver Client B: ssh -R 8001:internal.webserver:80 clientb@publicserver Client C: ssh -R 8002:internal.webserver:80 clientc@publicserver Basically, what we are trying to do is bind each user with a port and not allow them to tunnel to any other ports. If we were using the forward tunneling feature of SSH with ssh -L, we could permit which port to be tunneled by using the permitopen=host:port configuration. However, there is no equivalent for reverse SSH tunnel. Is there a way of restricting reverse tunneling ports per user?

  • RPi and Java Embedded GPIO: Sensor Reading using Java Code

    - by hinkmond
    And, now to program the Java code for reading the fancy-schmancy static electricity sensor connected to your Raspberry Pi, here is the source code we'll use: First, we need to initialize ourselves... /* * Java Embedded Raspberry Pi GPIO Input app */ package jerpigpioinput; import java.io.FileWriter; import java.io.RandomAccessFile; import java.text.DateFormat; import java.text.SimpleDateFormat; import java.util.Calendar; /** * * @author hinkmond */ public class JerpiGPIOInput { static final String GPIO_IN = "in"; // Add which GPIO ports to read here static String[] GpioChannels = { "7" }; /** * @param args the command line arguments */ public static void main(String[] args) { try { /*** Init GPIO port(s) for input ***/ // Open file handles to GPIO port unexport and export controls FileWriter unexportFile = new FileWriter("/sys/class/gpio/unexport"); FileWriter exportFile = new FileWriter("/sys/class/gpio/export"); for (String gpioChannel : GpioChannels) { System.out.println(gpioChannel); // Reset the port unexportFile.write(gpioChannel); unexportFile.flush(); // Set the port for use exportFile.write(gpioChannel); exportFile.flush(); // Open file handle to input/output direction control of port FileWriter directionFile = new FileWriter("/sys/class/gpio/gpio" + gpioChannel + "/direction"); // Set port for input directionFile.write(GPIO_IN); directionFile.flush(); } And, next we will open up a RandomAccessFile pointer to the GPIO port. /*** Read data from each GPIO port ***/ RandomAccessFile[] raf = new RandomAccessFile[GpioChannels.length]; int sleepPeriod = 10; final int MAXBUF = 256; byte[] inBytes = new byte[MAXBUF]; String inLine; int zeroCounter = 0; // Get current timestamp with Calendar() Calendar cal; DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss.SSS"); String dateStr; // Open RandomAccessFile handle to each GPIO port for (int channum=0; channum Then, loop forever to read in the values to the console. // Loop forever while (true) { // Get current timestamp for latest event cal = Calendar.getInstance(); dateStr = dateFormat.format(cal.getTime()); // Use RandomAccessFile handle to read in GPIO port value for (int channum=0; channum Rinse, lather, and repeat... Compile this Java code on your host PC or Mac with javac from the JDK. Copy over the JAR or class file to your Raspberry Pi, "sudo -i" to become root, then start up this Java app in a shell on your RPi. That's it! You should see a "1" value get logged each time you bring a statically charged item (like a balloon you rub on the cat) near the antenna of the sensor. There you go. You've just seen how Java Embedded technology on the Raspberry Pi is an easy way to access sensors. Hinkmond

  • How could two processes bind onto the same port?

    - by Matt Ball
    I just ran into an issue where a request made to localhost:8080 from curl was hitting a different server than the same request made from inside Node. lsof -i :8080 revealed that two processes were both binding onto the same port: COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME node 51961 mball 14u IPv4 0xd980e0df7f175e13 0t0 TCP *:http-alt (LISTEN) java 62704 mball 320u IPv6 0xd980e0df7fe08643 0t0 TCP *:http-alt (LISTEN) How is this possible? Were they binding onto different interfaces? Or was it the IPv4 vs 6? If you're curious, node was hitting the other node process, curl was hitting the java process. The java process was started after the node process.

  • How can you connect three external displays to a laptop with only one vga or dvi port and plenty of

    I have had some success with usb docks like this Universal Docking Station by Kensington to connect one external display to my laptop while using the onboard vga port for another display. But that's only two displays and I'm shooting for three. All I do is develop software and work in Photoshop... no games. For the sake of discussion, we can assume a Thinkpad or equivalent laptop with Windows 7 (I'm hoping for a platform-agnostic solution). How could I do this?

  • VS2013: How to debug a web application under a specific app domain?

    - by burnt1ce
    I have a few applications running under one app domain using port 80. I'm using port 80 to test and develop web application code. I want to take those same applications and publish them in a different app domain under a different port, 8001. This way, clients can view my applications that's using port 8001 while I develop and compile my project on port 80. However, when I debug my application, it freezes both the web applications on both port 80 and 8001. How can I debug my application under port 80 without affecting the web applications under port 8001?

  • Django : presenting a form very different from the model and with multiple field values in a Django-

    - by sebpiq
    Hi ! I'm currently doing a firewall management application for Django, here's the (simplified) model : class Port(models.Model): number = models.PositiveIntegerField(primary_key=True) application = models.CharField(max_length=16, blank=True) class Rule(models.Model): port = models.ForeignKey(Port) ip_source = models.IPAddressField() ip_mask = models.IntegerField(validators=[MaxValueValidator(32)]) machine = models.ForeignKey("vmm.machine") What I would like to do, however, is to display to the user a form for entering rules, but with a very different organization than the model : Port 80 O Not open O Everywhere O Specific addresses : --------- delete field --------- delete field + add address field Port 443 ... etc Where Not open means that there is no rule for the given port, Everywhere means that there is only ONE rule (0.0.0.0/0) for the given port, and with specific addresses, you can add as many addresses as you want (I did this with JQuery), which will make as many rules. Now I did a version completely "handmade", meaning that I create the forms entirely in my templates, set input names with a prefix, and parse all the POSTed stuff in my view (which is quite painful, and means that there's no point in using a web framework). I also have a class which aggregates the rules together to easily pre-fill the forms with the informations "not open, everywhere, ...". I'm passing a list of those to the template, therefore it acts as an interface between my model and my "handmade" form : class MachinePort(object): def __init__(self, machine, port): self.machine = machine self.port = port @property def fully_open(self): for rule in self.port.rule_set.filter(machine=self.machine): if ipaddr.IPv4Network("%s/%s" % (rule.ip_source, rule.ip_mask)) == ipaddr.IPv4Network("0.0.0.0/0"): return True else : return False @property def partly_open(self): return bool(self.port.rule_set.filter(machine=self.machine)) and not self.fully_open @property def not_open(self): return not self.partly_open and not self.fully_open But all this is rather ugly ! Do anyone of you know if there is a classy way to do this ? In particular with the form... I don't know how to have a form that can have an undefined number of fields, neither how to transform these fields into Rule objects (because all the rule fields would have to be gathered from the form), neither how to save multiple objects... Well I could try to hack into the Form class, but seems like too much work for such a special case. Is there any nice feature I'm missing ?

  • Scriptable FTPS client able to send Keep Alive to control port?

    - by schultkl
    We need a FTP client that satisfies the following constraints: Windows Command-line scriptable, so we can automate it...sorry, FileZilla (?) FTPS, as it seems to perform better than SFTP The ability to send KeepAlive commands to the FTPS control port No passwords sent on the command line...sorry, curl Number 4, above, is critical: we have set KeepAlive in some other clients (e.g., CoreFTP LE) but we seem to have some routing equipment in the server environment which drops our connection when transferring a 7GB+ file. We have also set passive mode and "resume transfer" functionality seems currently broken with this secure file transport server...so we need to download the file in one go. What FTPS clients might meet our needs?

  • RAID across SAS controller ports

    - by BlueGene
    Hi, I'm managing a HP DL360 G5 machine. It has a SAS controller with two ports. Port 1 is attached to 4 drive bays and Port 2 has 2 bays. The machine currently has 3 drives connected to Port 1 with RAID 5 configuration. I'm trying to max out the bays by adding 1 disk in port 1 and 2 in port 2. Can I group those three disks(1 disk-port, 2 disks-port 2) in a RAID 5 configuration?

  • VLAN trunking between Juniper EX -> Cisco Catalyst -> and Cisco Router

    - by Hugo Garcia
    I have the following scenario: EX2200 Switch whit ge-0/0/6 set as an access port on VLAN 80 ge-0/0/0 set as a trunk port connected to a catalyst switch and various vlans allowed to pass includin vlan 80 On the Catalyst Switch. port #3 set up as a trunk port that receives traffic from the EX switch. port 46 is set up also as a trunk port that connects to a cisco router. Port #48 is where the host used to be connected host - EX2200 - Catalyst - Router the problem is that this EX2200 is a new addition to the network and the host connected previosly to the catalyst switch. traffic is not getting from the host to the router, but the router can send ARP request to the host. following is the relevant configuration: Catalyst Switch: interface GigabitEthernet1/46 switchport trunk encapsulation dot1q switchport trunk allowed vlan 80,82,83,93,289 switchport mode trunk mtu 1532 media-type rj45 speed 1000 duplex full arp timeout 300 ! interface GigabitEthernet1/48 switchport access vlan 80 switchport mode access mtu 1532 media-type rj45 speed 100 duplex full arp timeout 300 no cdp enable !

  • How do I point one virtual host to another instance of apache running at another port on the same bo

    - by sacamano
    Hi there. I've got two apache2 instances running on my box. One came with a bitnami redmine stack which sole purpose is to host Redmine at host:8080/redmine. The other apache instance is running with php and such and is where I specify all the VHosts for my domains. Now I'd like to point redmine.somedomain.com at www.somedomain.com:8080/redmine so that redmine is accessible through a subdomain and on port 80. Redmine is a Ruby on Rails app and runs with Phusion Passenger so I can't just point the vhost to the htdocs directory of the redmine install. How is this done? I've tinkered with ProxyPass and ProxyPassReverse but I just can't get it working. All help is greatly appreciated.

  • Cascading switches: uplink to uplink?

    - by wuckachucka
    I'm a bit confused as to why I haven't seen any references online to using Switch A's uplink port (1Gbps, 24-port 10/100) to connect to Switch B's uplink port: everything I've seen -- including documentation, forums, articles, etc. -- has Switch A's uplink port going to one of Switch B's 10/100 access ports. As I understand it, the Uplink port (besides greater speed normally) is no different than another port except that it's "internally crossed-over" so that you can use a straight cable with it. I've also seen documentation on using the uplink port to connect a switch to a gateway router, or even a server, as it provides greater bandwidth than the access ports, but yet not sure why nobody seems to be cross-uplinking, even when there's 2 uplink ports available on some higher-end switches. Switch in question is Linksys SRW224P (x2). Am I missing something?
