  • Middleware with generic communication media layer

    - by Tom
    Greetings all, I'm trying to implement middleware (driver) for an embedded device with generic communication media layer. Not sure what is the best way to do it so I'm seeking an advice from more experienced stackoverflow users:). Basically we've got devices around the country communicating with our servers (or a pda/laptop in used in field). Usual form of communication is over TCP/IP, but could be also using usb, RF dongle, IR, etc. The plan is to have object corresponding with each of these devices, handling the proprietary protocol on one side and requests/responses from other internal systems on the other. The thing is how create something generic in between the media and the handling objects. I had a play around with the TCP dispatcher using boost.asio but trying to create something generic seems like a nightmare :). Anybody tried to do something like that? What is the best way how to do it? Example: Device connects to our Linux server. New middleware instance is created (on the server) which announces itself to one of the running services (details are not important). The service is responsible for making sure that device's time is synchronized. So it asks the middleware what is the device's time, driver translates it to device language (protocol) and sends the message, device responses and driver again translates it for the service. This might seem as a bit overkill for such a simple request but imagine there are more complex requests which the driver must translate, also there are several versions of the device which use different protocol, etc. but would use the same time sync service. The goal is to abstract the devices through the drivers to be able to use the same service to communicate with them. Another example: we find out that the remote communications with the device are down. So we send somebody out with PDA, he connects to the device using USB cable. Starts up the application which has the same functionality as the timesync service. Again middleware instance is created (on the PDA) to translate communication between application and the device this time only using USB/serial media not TCP/IP as in previous example. I hope it makes more sense now :) Cheers, Tom

  • How to connect an existing strongly-typed data set to a different server at run time?

    - by Kiril
    I am coding a simple space empire management game in Visual C# 2008, which relies on connecting to a remote SQL server database to get/store data. I would like the user to be able to connect to a user-specified SQL server from the login screen(he specifies IP address, port, database name, ID, password and presses "connect" button). However, I found out that the Dataset connection string property is read only and cannot be changed. Is there any way to guide the wizard-generated DataSet to a user-specified server at run time?

  • Using UCMA to connect to 3CX?

    - by Rodney Burton
    Has anyone used Microsoft's UCMA 2.0 SDK to connect to 3CX's free IP PBX to add voice capabilities to their application? If so, does it work? What I am trying to accomplish is having a windows form app running on 2 or more computers, and each person can connect to another person and carry on a voice conversation using their headset connected to their computer. App is in C# w/ .NET3.5 SP1.

  • Is It Possible to get a (rough) Mobile Phone Location from a HTTP Request

    - by Tim Lytle
    If memory serves me correctly, google does this for the maps site. I know google's mobile maps app can determine the rough location (I assume using some kind of cell tower lookup), yet I seem to remember the site getting somewhat close to the current location when viewing on a mobile browser. Anyone know how/if that's possible? Does the IP address change based on the tower or area (seems like they'd be using some kind of gateway common to the carrier)?

  • 9000+ different subdomains 301 to main domain, .htacess apache

    - by Karim
    I bought a domain that had various subdomains such as Kim.domain.com/whatever john.domain.com/whatever1 Lizo.domain.com/whatever2 Simon.domain.com/whatever1 And this was in the thousands, and also had links to these pages I'd like to do a 301 redirect for all these urls into http://domain.com Any idea how this could be done? This is for a apache web server and needs to be done via .htaccess I have implemented the solution from reading the answer below. RewriteEngine On RewriteCond %{HTTP_HOST} !^www. domain.com$ RewriteCond %{HTTP_HOST} !^$ RewriteRule ^/(.*)$ http:/ / www. domain.com/$1 [L,R=301] However I have a slight problem, I would like to redirect all subdomains + subfolders to http://www. domain.com/ With the exception of http: //domain. com/subfolder/, in which case I would like to redirect to http: // www.domain. com/subfolder/ [i.e. exception for no subdomain] I'm guessing I need to add an exception, what can I do to implement this. Note: example URLs above have had spaces added to them to prevent spam blocks for blocking the post.

  • Allow outgoing connections using 'iptables'

    - by umanga
    Greeting all, "iptables -L" gives the following output [root@ibmd ~]# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination Server has global IP and can be accessed from outer IPs.But I cannot ping nor telnet to any port (including TCP 80) from the server. Does this has something to do with my 'iptables' settings ? Any tips on allow access from my server? thanks in advance.

    ereg and eregi functions will be deleted from Php. Please help to find alternatives for the following ereg functions: 1) To allow IP addresses only for specific ranges: $targetAddr = "60.37..*..*"; if (!ereg($targetAddr, $_SERVER['REMOTE_ADDR'])) { die; } 2) To replace series of points like ....................... $message = ereg_replace("[.]{3,}", "...

  • Cannot connect to remote mail server for sending emails in ASP.NET

    - by Dave
    I want to migrate a web application from a Windows Server 2003 to a Windows Server 2008 R2. All works fine except sending emails from the application. If I configure the application to use the smtp server on "localhost" it works, but changing it to the "real" host name (e.g. mail.example.org) no mail is sent. The error message says, that the remote server needs a secure connection or smtp authentication. But since it works when using "localhost" instead of the host name I doubt that this is the problem. Also it's unlikely a problem with the mail server, I also tried it with another one. So for me it seems like the firewall is blocking the outgoing connection to the mail server. I tried to open port 25, but it still did not work. Maybe I just did it the wrong way. Update: For clarifying my setup: I have a Windows Server 2008 R2 with hMailServer installed (set up for some of the hosted domains) For the website I'm talking about I need to use an external mail server (totally different hosting provider) Apparently I was a bit off the track. It seems like it works when using connecting to the local mail server either with the host name "localhost" or "mail.somedomain.com" (while somedomain.com is set up in my mail server). But when using the host name of the external mail server ("mail.externaldomain.com") it seems like it tries to connect to the local server again, although this domain is not set up in the mail server. Thanks to Evan Anderson for the tip to use telnet - why I have not thought of it myself?... :-) Note, the website www.externaldomain.com is hosted on my server but the DNS entries are maintained by the other hosting provider. "externaldomain.com" is the only entry which points to my server all other records (MX, subdomains) are pointing to the other server. So I think the question is now, how do i bring my server to connect to the external mailserver. Do I have to configure this in my mail server or is it a windows server thing?

  • What's the right way to communicate between 2 or more .Net applications running on a same computer w

    - by Ivan
    If my applications run on a same computer or even on different computers in a same LAN and need intense and quick communication, it seems illogical for me to use text-encoded web services and HTTP. I could possibly use IP/TCP/UDP sockets and invent my own protocols, but believe there is a standard way for .Net applications to send/receive object instances (and, maybe, even sharing an object by reference?). Can you tell me what's that standard way? I am only interested in .Net Framework 4 applications and don't need to support legacy frameworks.

  • Can I make ruby send network traffic over a specific iface?

    - by rjorgenson
    I am writing a script that grabs the external IP address along with some other information about each iface. I can't figure out how to make ruby send traffic over a specific iface(eth0 and wlan0 for example). I am currently using the open-uri library to open http://whatismyip.org and read it into a variable. def get_external_ip begin open("http://whatismyip.org") { |f| return f.read } rescue return "none" end end Is there any way to specify this at runtime of the script or from within the script itself(ideally)?

  • Lighttpd check request headers in configuration

    - by Mike Hayes
    Hi I was wondering if it was possible in the configuration of Lighttpd to read request headers, I've searched and searched.. apparently it's not possible. For example, conditional configuration based upon IP address: $HTTP["remoteip"] == "0.0.0.0" { // Do something } Is there something similar to check headers, for example: $HTTP["X-Some-Header"] == "Value" { // Do something } I'm thinking there isn't but thought I would post here as a last resort. Google didn't help much, and Lighttpd documentation would suggest this is not possible. Thanks Mike

  • iptables secure squid proxy

    - by Lytithwyn
    I have a setup where my incoming internet connection feeds into a squid proxy/caching server, and from there into my local wireless router. On the wan side of the proxy server, I have eth0 with address 208.78.∗∗∗.∗∗∗ On the lan side of the proxy server, I have eth1 with address 192.168.2.1 Traffic from my lan gets forwarded through the proxy transparently to the internet via the following rules. Note that traffic from the squid server itself is also routed through the proxy/cache, and this is on purpose: # iptables forwarding iptables -A FORWARD -i eth1 -o eth0 -s 192.168.2.0/24 -m state --state NEW -j ACCEPT iptables -A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A POSTROUTING -t nat -j MASQUERADE # iptables for squid transparent proxy iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j DNAT --to 192.168.2.1:3128 iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128 How can I set up iptables to block any connections made to my server from the outside, while not blocking anything initiated from the inside? I have tried doing: iptables -A INPUT -i eth0 -s 192.168.2.0/24 -j ACCEPT iptables -A INPUT -i eth0 -j REJECT But this blocks everything. I have also tried reversing the order of those commands in case I got that part wrong, but that didn't help. I guess I don't fully understand everything about iptables. Any ideas?

  • fail2ban block ports rules iptable

    - by J Spen
    I just installed Ubuntu Server 14.04 and don't have much experience with IPtables. I am trying to get a basic setup going where I only accept SSH connections on port 22 and 2222. I actually have that working with no problem using fail2ban ssh. Then I wanted to block all other ports except 423 and 4242 but either method of DROPing all connections that are not listed seems not to work and it blocks me out of everything. Below is the setup that works: -P INPUT ACCEPT -P FORWARD ACCEPT -P OUTPUT ACCEPT -N fail2ban-ssh -A INPUT -p tcp -m multiport --dports 22,2222 -j fail2ban-ssh -A fail2ban-ssh -j RETURN I tried to change it either to: -P INPUT DROP -P FORWARD ACCEPT -P OUTPUT ACCEPT -N fail2ban-ssh -A INPUT -p tcp -m multiport --dports 22,2222 -j fail2ban-ssh -A fail2ban-ssh -j RETURN or: -P INPUT ACCEPT -P FORWARD ACCEPT -P OUTPUT ACCEPT -N fail2ban-ssh -A INPUT -p tcp -m multiport --dports 22,2222 -j fail2ban-ssh -A INPUT -j DROP -A fail2ban-ssh -j RETURN I have noticed that the rules for fail2ban-ssh are automatically added to my iptables on boot because if I save them with iptables-persistant they are entered twice. How do I go about blocking everything accept those 2 ports using fail2ban? Is it a bad fail2ban configuration or do I need to add the fail2ban-ssh -j Return somewhere else in my code.

  • Xorg input devices fail without udev

    - by Sampo
    What I am trying to do: Launch Xorg server without udev device manager. What I have tried to do: Make sure that /dev/ has all required nodes, such as /dev/input/*. Make sure that all required kernel modules are loaded. Launch Xorg. What happens: Xorg starts up as excepted. Xorg loads correct GPU driver and sets right screen resolution. Xorg blocks all input devices (keyboard, mouse), Alt+F[1-12] does not work (can't go back to tty1). Unraw'ing keyboard to take its control from X removes blocking and after unraw I can Alt+F1 back to tty1. Xorg still does not handle any input. Why I think that it should work: Same configuration works well if udev is loaded. Loading udev does not add or modify /dev/ contents, all nodes stays same. My main question is: How to make Xorg input devices work without udev? Any additional information about how Xorg really uses/detects/grabs keyboard would be helpful. And any additional information about what udev really does (other than populating /dev/) would also be helpful.

  • ssh_exchange_identification: Connection closed by remote host

    - by rick
    Firstly, I know that this question has been asked a million times, and I have read everything I can find and still cannot fix the problem. i am encountering this issue when ssh'ing in from my mac to my Ubuntu server on a fresh install of Ubuntu (I reinstalled because of this issue). I have SSH portmapped to 7070 because my ISP is blocking 22. On the client: bash: ssh -p 7070 -v [email protected] debug1: Reading configuration data /etc/ssh_config debug1: Connecting to address.org port 7070. debug1: Connection established. debug1: identity file /home/me/.ssh/identity type -1 debug1: identity file /home/me/.ssh/id_rsa type 1 debug1: identity file /home/me/.ssh/id_dsa type -1 ssh_exchange_identification: Connection closed by remote host Here's what I have done to try to resolve the issue: Made sure my maxstartups is ok: bash: grep MaxStartups /etc/ssh/sshd_config #MaxStartups 10:30:60 Made sure hosts.deny is clear of denials. Made sure hosts.allow has my client IP. Clear out known_hosts on client Changed ownership of /var/run to root Made sure etc/run/ssh is Made sure /var/empty exists Reinstall openssh-server Reinstall ubuntu When I run telnet localhost, I get this: telnet localhost Trying ::1... Trying 127.0.0.1... telnet: Unable to connect to remote host: Connection refused When I run /usr/sbin/sshd -t Could not load host key: /etc/ssh/ssh_host_rsa_key Could not load host key: /etc/ssh/ssh_host_dsa_key When I regenerate the keys with ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key I get the same error. I am pretty sure this is the issue. Can anyone help?
