• Two routers in a LAN

  - by taxi

  router A no wifi +--- pc01 +--- pc02 | +--- router B wifi +--- pc03 +--- printer In my LAN I have a modem-router (say A) (no wifi connection) acting as DHCP server, and connected to the Internet. Now, I want to add another router (say B) (with wifi connection) to the LAN, in order to connect wifi pc's and net printers. Here I would disable DCHP server functionality. Is it correct to connect router B to router A via an ethernet port? In router A I define an IP address (eg 192.168.1.100) to be assigned to router B (MAC address). I expect to see router B listed as an attached device, in router A's status, but on the contrary it is not listed.

• A really unique case of Load Balancing

  - by Shamshun

  I have an internet connection which has limited up/down bandwidth per IP address. What I want to do is to get multiple IP addresses on a "single" LAN interface, and use a load balancer to distribute traffic through them. I was successful at getting 100 ip addresses on a single interface. my problem is that Linux and Windows use the first ip address of an interface by default, so my bandwidth is not increased. I would appreciate if someone tells me what Load Balancing software has the ability to distribute load between multiple IPs on a single interface. I have tried to do so on both Win7 and Backtrack-LinuxR2

• How Do I Get To Preferences In FireFox

  - by user123

  I'm currently trying to get to preferences in FireFox in Linux Ubuntu. Because I don't have 10 reputation, I can't post an image (otherwise I would). All I see in the browser is the Address Bar, Downloads and Home. If I right-click (or left click) on any of these, I don't have further options (other than Home, but it only allows me to add items to the toolbar, none of which are Preferences/Options/Etc). I tried vising a website to see if more options would open; nothing. I tried right clicking on the main page and each toolbar item (listed) to see if there was another options like "Preferences" or "Options"; nothing. I tried entering "Preferences" in the address bar, thinking maybe it would open automatically; nothing. I tried right clicking on FireFox on the Linux Menu to see if I could open options without opening the program (and tried this even when the program was open); nothing.

• Wrapping a point-to-point link

  - by user3712955

  I'm using a pair of IP radios (non-WiFi) to bridge my office engineering LAN (172.0.0.0/8) to a lab in another building. The radios work fine, but they expose a web management interface I'd like to hide, and they also generate traffic (ARP, STP, and more) that I need to keep off my (very, very clean) LAN segments. I have some ARM-Linux boards (similar to Beagle/Panda/RasPi) running Ubuntu, and I've put one at each end of the link, between the radio and the LAN. Each of the boards has 2 wired Ethernet interfaces, eth0 and eth1. The LAN segments are connected to eth0, and the radios are connected to eth1. I'd like to accomplish the following: Keep radio-originated traffic off my LAN segments! Hide all services provided by the radio (web, ssh, etc.) Transparently pass all traffic between the LAN segments (including things like ARP). The above also applies to the ARM-Linux boards: No stray traffic my LAN from them either! I'd like the system to look like a switch: LAN packets arriving at one eth0 appear at the other. And neither eth0 should have an IP address: The working system should behave like a CAT6 cable with some latency (instead of ARM boards and radios). Unfortunately, I'm confused about how to properly configure the ARM Ubuntu systems. What I'm guessing I need is a bridge on each board (br0?) and a VLAN (vlan0 or eth0.0?) to isolate the LAN traffic from everything else as it passes through the ARM boards and the radios. Then I need some kind of a firewall to block sending anything out eth0 that isn't from the other eth0 (via the VLAN). I've looked at the ip and ebtables commands (especially -t broute). While the concepts sorta-kinda make sense, I'm completely lost in the details. Edit: In the perverse case that a system on one of my LAN segments has the same IP address as one of the radios, or as eth1 on the ARM-Ubuntu boards, a VLAN won't work. Which I believe means I need to tunnel all traffic between the two eth0 interfaces to get that "like a wire" behavior. Help? Finally, I'd like to have a way to temporarily expose services on the ARM boards (ssh) and the radios (web) for maintenance purposes. Ideally, it would expose an IP address with ssh available on port 22. Once connected, I figure I'd start an X11 session and run a browser on the ARM board to access the radios. Or something. I could login via the console to enable/disable this, or perhaps could use a GPIO to trigger a script. I feel I've identified most of the pieces needed to make all this happen, but I have no idea how to combine them to make a working system. Thanks!

• Windows 7 computer apparently connected to working wireless network but can't access router page or internet

  - by Hemmer

  I can consistently connect successfully to both the router and the internet using both my phone and two different computers which strongly suggests that the issue is at the desktop end. Only my Windows 7 desktop machine has stopped getting internet connectivity. It manages to connect to the router's network using the Windows 7 wireless dialog, but can't access either the router configuration page (192.168.1.1) or the internet in general once connected. The strange thing is the wireless network icon in the notification bar shows a full strength signal, sometimes with the yellow warning triangle. The output of ipconfig /all is: Wireless LAN adapter Wireless Network Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Broadcom 802.11g Network Adapter Physical Address. . . . . . . . . : 00-12-17-94-98-90 DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 192.168.1.102(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Lease Obtained. . . . . . . . . . : 08 June 2011 10:32:16 Lease Expires . . . . . . . . . . : 08 June 2011 12:32:16 Default Gateway . . . . . . . . . : 192.168.1.1 DHCP Server . . . . . . . . . . . : 192.168.1.1 DNS Servers . . . . . . . . . . . : 194.168.4.100 194.168.8.100 NetBIOS over Tcpip. . . . . . . . : Enabled I've tried renewing DCHP settings disabling IPv6 resetting TCP stack uninstalling and reinstalling WLAN card drivers I've not installed anything new or made any changes to my knowledge, this just happened out of the blue.

• How can I redirect HTTP(S) traffic to another gateway?

  - by PsyStyle

  I have a network like 192.168.0.0/15 with the default gateway set to 192.168.0.1. All the workstations of the network use this gateway for all kind of accesses to the Internet. Now I am testing a new Internet connection with another provider and for that I'm using a second gateway on the same subnet with 192.168.0.2 as IP address. I want to redirect only HTTP and HTTPS traffic to this second gateway keeping untouched the address of the default gateway set inside every workstation. How can I accomplish this task? What I have to change inside the first's gateway firewall configuration or routes? I tried with a DNAT like: DNAT loc:192.168.0.1 loc:192.168.0.2 tcp 80 but nothing worked. I use Shorewall for simplicity in configuration but I can understand even theorical answers which I will try to adapt to my case.

• How can I set clean urls (enable rewrite) if I don't have a domain ?

  - by Patrick

  In order to enable clean urls in Drupal, I add the lines below to the lighttpd configuration file. However I'm now working on a local server and I don't have a domain available. So I need to work with this address http://local.ip/Sites/mywebsite I've tried to replace ["host"] with ["socket"] and replace the domain with ip and subfolders (see address above), but unsuccessfully. How can I set the configuration file to set clean urls even if I don't have a domain ? thanks $HTTP["host"] =~ "(^|\.)mywebsite\.com" { server.document-root = "/var/www/sites/mywebsite" server.errorlog = "/var/log/lighttpd/mywebsite/error.log" server.name = "mywebsite.com" accesslog.filename = "/var/log/lighttpd/mywebsite/access.log" include_shell "./drupal-lua-conf.sh mywebsite.com" url.access-deny += ( "~", ".inc", ".engine", ".install", ".info", ".module", ".sh", "sql", ".theme", ".tpl.php", ".xtmpl", "Entries", "Repository", "Root" ) # "Fix" for Drupal SA-2006-006, requires lighttpd 1.4.13 or above # Only serve .php files of the drupal base directory $HTTP["url"] =~ "^/.*/.*\.php$" { fastcgi.server = () url.access-deny = ("") } magnet.attract-physical-path-to = ("/etc/lighttpd/drupal-lua-scripts/p-.lua") }

• VPN on PC vs Mac

  - by allstar

  I am trying to connect to a VPN from my home computer, as opposed to my work computer which already has the network info set up. I have received instructions on connecting from a mac, but since I don't have that I'm trying to do the equivalent on my PC. I know the: server group name secret and my own login account and password Using the Windows 7 VPN, there's space for: Internet address destination name user name password domain (optional) I'm trying to determine what's what. I assume the internet address is the server. I've tried using the "secret" as the Password, b/c i'd think the first part is connecting to the VPN as opposed to logging in. It still wants a user name though. I tried mine, I tried the "group name". I would appreciate your help with this. Thanks!

• Virtualbox share guest (windows xp) printer to host(linux)

  - by M0E-lnx

  I have a weird situation. I own a printer that has 0 support in linux, but of course, it works in windows. So I have installed VirtualBox 3.1.2 with guest additions to provide access to my usb devices. I have successfully setup the printer and the guest os can print fine. Now, the question is: Is there any way to make this printer accessible to the host OS? I noticed that the guest OS takes an ip address of 10.0.2.15, but when I try to ping that address from the linux host, it goes nowhere. No response. Has anyone here done this before? can anyone think of a way to do this?

• Block a Server from reaching a machine

  - by user

  I have a Windows 2003 server that I want to block from accessing a specific IP address. I want to control this from the Server. because I control the machine. The traffic is http traffic (webservice call). It uses a non-standard port, so IP address+ Port combination would also work. Background: I have a development enviornment that for some reason is ignoring host file enteries under some circumstances. These host files point the enviornment at services in another Dev enviornment. Wne th host files are ignored, dev is talking to production. This is not my question, rather the motivation for this inquiry. I want is a failsafe to ensure dev will error instead of happily engaging in transactions with production. I control the dev server, I do not control the firewalls or the target production machine.

• My raspberry pi server hostname doesn't work?

  - by xSpartanCx

  The people over on the rPi forums don't have any answers for me... I've got a raspberry pi running raspbian server edition. My problem is that the only way I can ssh into it with putty is through the static ip. My router doesn't recognize the hostname; it shows the mac address as the name. This causes the pi not to show my apache2 website online (I think). The only way I've gotten it to work is using my other linux server to forward using virtual hosts, and that has to use the ip address, too. However, now that I have my other server off, the website doesn't work.

• How do I simplify my URLs with Apache (or DNS)?

  - by user45015

  I'm running Apache 2.2 with WHM / cPanel. Let me know what other info you need to answer this question. I want to set up some kind of forwarding/redirect so that the following occurs: _http://appname.mydomain.com/ (ignore the underscore, couldn't post actual links) actually sends you to _http://mydomain.com:8072/appname/ This can be overt (your browser address bar changes) or not, it doesn't really matter (although if I get to pick I would prefer the address bar NOT change). My initial thought was to use a CNAME, but I've since learned you can't include a port in your cname. Now I'm thinking I have to do something with my Apache VHOST? I am very much a novice at apache / web server internal workings, but I know my way around a command line well enough.

• Mirrored servers in data centers nationwide -- how? [closed]

  - by Sysadmin Evstar

  Possible Duplicate: Mirrored servers in data centers nationwide — how? Mirrored servers in data centers nationwide -- how? I flunked my IT interview by getting this question wrong. I thought that in the various metropolitan areas, an "http://google.com" request goes to the ISP's DNS server, which somehow returns an IP address for one of several geographically-nearby http servers, and then something internally rolls over to the next available local Google server. But then, I could not explain where the table of available local Google servers is actually cached, or the details of the IP address rollover. Or how they could manually take some server out of the rotation, from anywhere. So, what should I be reading now so I can ace this question next time? Also, what daemons run on these machines 24/7 to keep all those mirrored database disks synchronized?

• jquery selector for elements beside one another? [migrated]

  - by PaulHanak

  this SHOULD be simple, but I have been through the Jquery Selector help for about an hour now and nothing seems to be working. Help! I am basically trying to pull the text (an address) of a SPAN after a user clicks on the link next to it. Please note though, I will have about 10 on a page, so I cannot set a static address. It must be pulled when the user clicks. The html code: <a href="3" class="clicky">Click to Show Map</a> <span style="display: none" class="theaddy">123 Fake Street, Somewhere Else, 12341</span> So really, my question is, how do I grab the text from .theaddy when a user clicks on .clicky? As I said, I cannot use var propertyaddy = $(.theaddy).text(); because there are 10 of these addy's on the same page. I need some sort of "THIS" Next To kinda thing. I also tossed around the idea of placing the SPAN inside the A, but my efforts on that weren't working either. Thank you in advance for any help!

• How to configure multiple WCF binding configurations for the same scheme

  - by Sandor Drieënhuizen

  I have a set of IIS7-hosted net.tcp WCF services that serve my ASP.NET MVC web application. The web application is accessed over the internet. WCF Services (IIS7) <--> ASP.NET MVC Application <--> Client Browser The services are username authenticated, the account that a client (of my web application) uses to logon ends up as the current principal on the host. I want one of the services to be authenticated differently, because it serves the view model for my logon view. When it's called, the client is obviously not logged on yet. I figure Windows authentication serves best or perhaps just certificate based security (which in fact I should use for the authenticated services as well) if the services are hosted on a machine that is not in the same domain as the web application. That's not the point here though. Using multiple TCP bindings is what's giving me trouble. I tried setting it up like this in my client configuration: <bindings> <netTcpBinding> <binding> <security mode="TransportWithMessageCredential"> <message clientCredentialType="UserName"/> </security> </binding> <binding name="public"> <security mode="Transport"> <message clientCredentialType="Windows"/> </security> </binding> </netTcpBinding> </bindings> <client> <endpoint contract="Server.IService1" binding="netTcpBinding" address="net.tcp://localhost:8081/Service1.svc"/> <endpoint contract="Server.IService2" binding="netTcpBinding" address="net.tcp://localhost:8081/Service2.svc"/> </client> The server configuration is this: <bindings> <netTcpBinding> <binding portSharingEnabled="true"> <security mode="TransportWithMessageCredential"> <message clientCredentialType="UserName"/> </security> </binding> <binding name="public"> <security mode="Transport"> <message clientCredentialType="Windows"/> </security> </binding> </netTcpBinding> </bindings> <services> <service name="Service1"> <endpoint contract="Server.IService1, Library" binding="netTcpBinding" address=""/> </service> <service name="Service2"> <endpoint contract="Server.IService2, Library" binding="netTcpBinding" address=""/> </service> </services> <serviceHostingEnvironment> <serviceActivations> <add relativeAddress="Service1.svc" service="Server.Service1"/> <add relativeAddress="Service2.svc" service="Server.Service2"/> </serviceActivations> </serviceHostingEnvironment> The thing is that both bindings don't seem to want live together in my host. When I remove either of them, all's fine but together they produce the following exception on the client: The requested upgrade is not supported by 'net.tcp://localhost:8081/Service2.svc'. This could be due to mismatched bindings (for example security enabled on the client and not on the server). In the server trace log, I find the following exception: Protocol Type application/negotiate was sent to a service that does not support that type of upgrade. Am I looking into the right direction or is there a better way to solve this?

• Calling a WCF service from another WCF service

  - by ultraman69

  Hi ! I have a WCF service hosted on a windows service on my Server1. It also has IIS on this machine. I call the service from a web app and it works fine. But within this service, I have to call another WCF sevice (also hosted on a windows service) located on Server2. The security credentials are set to "Message" and "Username". I have an error like "SOAP protcol negociation failed". It's a problem with my server certificate public key that doesn't seem to be recognise. However, if I call the service on the Server2 from Server1 in a console app, it works fine. I followed this tutorial to set up my certificates : http://www.codeproject.com/KB/WCF/wcf_certificates.aspx Here's the config file from my service on Server1 that tries to call the second one : <endpoint address="" binding="wsHttpBinding" contract="Microsoft.ServiceModel.Samples.ITraitement" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <client> <endpoint address="http://Server2:8000/servicemodelsamples/service" behaviorConfiguration="myClientBehavior" binding="wsHttpBinding" bindingConfiguration="MybindingCon" contract="Microsoft.ServiceModel.Samples.ICalculator" name=""> <identity> <dns value="ODWCertificatServeur" /> </identity> </endpoint> </client> <bindings> <wsHttpBinding> <binding name="MybindingCon"> <security mode="Message"> <message clientCredentialType="UserName" /> </security> </binding> </wsHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="ServiceTraitementBehavior"> <serviceMetadata httpGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="True" /> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="myClientBehavior"> <clientCredentials> <clientCertificate findValue="MachineServiceTraitement" x509FindType="FindBySubjectName" storeLocation="LocalMachine" storeName="My" /> <serviceCertificate> <authentication certificateValidationMode="ChainTrust" revocationMode="NoCheck"/> </serviceCertificate> </clientCredentials> </behavior> </endpointBehaviors> </behaviors> And here's the config file from the web app that calls the service on Server1 : <system.serviceModel> <bindings> <wsHttpBinding> <binding name="WSHttpBinding_ITraitement" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="Message"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" algorithmSuite="Default" establishSecurityContext="true" /> </security> </binding> </wsHttpBinding> </bindings> <client> <endpoint address="http://localhost:8020/ServiceTraitementPC" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_ITraitement" contract="ITraitement" name="WSHttpBinding_ITraitement"> </endpoint> </client> Any idea why it works if if I call it in a console app and not from my service ? Maybe it has something to do with the certificateValidationMode="ChainTrust" ?

Am I looking into the right direction or is there a better way to solve this?

• Combined SOAP/JSON/XML in WCF, using UriTemplate

  - by gregmac

  I'm trying to build a generic web service interface using WCF, to allow 3rd party developers to hook into our software. After much struggling and reading (this question helped a lot), I finally got SOAP, JSON and XML (POX) working together. To simplify, here's my code (to make this example simple, I'm not using interfaces -- I did try this both ways): <ServiceContract()> _ Public Class TestService Public Sub New() End Sub <OperationContract()> _ <WebGet()> _ Public Function GetDate() As DateTime Return Now End Function '<WebGet(UriTemplate:="getdateoffset/{numDays}")> _ <OperationContract()> _ Public Function GetDateOffset(ByVal numDays As Integer) As DateTime Return Now.AddDays(numDays) End Function End Class and the web.config code: <services> <service name="TestService" behaviorConfiguration="TestServiceBehavior"> <endpoint address="soap" binding="basicHttpBinding" contract="TestService"/> <endpoint address="json" binding="webHttpBinding" behaviorConfiguration="jsonBehavior" contract="TestService"/> <endpoint address="xml" binding="webHttpBinding" behaviorConfiguration="poxBehavior" contract="TestService"/> <endpoint address="mex" contract="IMetadataExchange" binding="mexHttpBinding" /> </service> </services> <behaviors> <endpointBehaviors> <behavior name="jsonBehavior"> <enableWebScript/> </behavior> <behavior name="poxBehavior"> <webHttp /> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="TestServiceBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> </behaviors> This actually works -- I'm able to go to TestService.svc/xml/GetDate for xml, TestService.svc/json/GetDate for json, and point a SOAP client at TestService.svc?wsdl and have the SOAP queries work. The part I'd like to fix is the queries. I have to use TestService.svc/xml/GetDateOffset?numDays=4 instead of TestService.svc/xml/GetDateOffset/4. If I specify the UriTemplate, I get the error: Endpoints using 'UriTemplate' cannot be used with 'System.ServiceModel.Description.WebScriptEnablingBehavior'. But of course without using <enableWebScript/>, JSON doesn't work. The only other thing I've seen that I think will work is making 3 different services (.svc files), that all implement an interface that specifies the contract, but in the classes specify different WebGet/WebInvoke attributes on each class. This seems like a lot of extra work, that frankly, I don't see why the framework doesn't handle for me. The implementation of the classes would all be the same, except for the attributes, which means over time it would be easy for bugs/changes to get fixed/done in one implementation but not the others, leading to inconsistent behaviour when using the JSON vs SOAP implementation for example. Am I doing something wrong here? Am I taking a totally wrong approach and misusing WCF? Is there a better way to do this? With my experience doing web stuff, I think it should be possible for some kind of framework to handle this ... I even have an idea in my head of how to build it. It just seems like WCF is supposed to be doing this, and I don't really want to reinvent the wheel.

• mexTcpBinding in WCF - IMetadataExchange errors

  - by David

  I'm wanting to get a WCF-over-TCP service working. I was having some problems with modifying my own project, so I thought I'd start with the "base" WCF template included in VS2008. Here is the initial WCF App.config and when I run the service the WCF Test Client can work with it fine: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.web> <compilation debug="true" /> </system.web> <system.serviceModel> <services> <service name="WcfTcpTest.Service1" behaviorConfiguration="WcfTcpTest.Service1Behavior"> <host> <baseAddresses> <add baseAddress="http://localhost:8731/Design_Time_Addresses/WcfTcpTest/Service1/" /> </baseAddresses> </host> <endpoint address="" binding="wsHttpBinding" contract="WcfTcpTest.IService1"> <identity> <dns value="localhost"/> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> <behaviors> <serviceBehaviors> <behavior name="WcfTcpTest.Service1Behavior"> <serviceMetadata httpGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="True" /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> </configuration> This works perfectly, no issues at all. I figured changing it from HTTP to TCP would be trivial: change the bindings to their TCP equivalents and remove the httpGetEnabled serviceMetadata element: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.web> <compilation debug="true" /> </system.web> <system.serviceModel> <services> <service name="WcfTcpTest.Service1" behaviorConfiguration="WcfTcpTest.Service1Behavior"> <host> <baseAddresses> <add baseAddress="net.tcp://localhost:1337/Service1/" /> </baseAddresses> </host> <endpoint address="" binding="netTcpBinding" contract="WcfTcpTest.IService1"> <identity> <dns value="localhost"/> </identity> </endpoint> <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange"/> </service> </services> <behaviors> <serviceBehaviors> <behavior name="WcfTcpTest.Service1Behavior"> <serviceDebug includeExceptionDetailInFaults="True" /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> </configuration> But when I run this I get this error in the WCF Service Host: System.InvalidOperationException: The contract name 'IMetadataExchange' could not be found in the list of contracts implemented by the service Service1. Add a ServiceMetadataBehavior to the configuration file or to the ServiceHost directly to enable support for this contract. I get the feeling that you can't send metadata using TCP, but that's the case why is there a mexTcpBinding option?

• Connecting WCF from Webpart

  - by Bhaskar

  I am consuming a WCF Service from a webpart in Sharepoint 2007. But its giving me the following error: There was no endpoint listening at http://locathost:2929/BusinessObjectService that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. --- System.Net.WebException: The remote server returned an error: (404) Not Found.

So, I guess the URL is definately correct. Please help !!!

• General website publishing questions involving domain forwarding issue

  - by Gorgeousyousuf

  Even though I have been having a certain level of knowledge and experience about web development I have never interested in obtaining a domain and publishing a website from my own server. Since today I have been struggling with getting my own domain and configuring it utilizing web sources. I started with learning the outline of web publishing process including web server installation, deploying a website for testing purpose,router port forwarding, getting a domain and forwarding domain to my router which will also forward http requests to my web server I am confused about some parts and so far could not get the web site accessed from outside of the network. All I try to do is just for learning purpose so I do not pay much attention to security issues for now. I have Server 2008 and IIS 7.5 installed. I use a laptop and have access to the modem over wireless and my modem is Zoom x6 5590. Well I will continue explaining what I have done so far and what I think will be after each action I did, I have successfully had access to my website on any local computer entering the internal ip address and port pair of the host machine in a browser. Next, I forwarded port 80 of my host machine creating a virtual server like 10.0.0.x(internal ip(static) of the host) - tcp - start port : 80 - end port : 80 in router options. Now I suppose every request that will come to the public Ip on port 80 will be forwarded to my host machine(10.0.0.x) over port 80. So If everyhing went as desired, the website listening on port 80 will accept the request and process the issue and finally respond bla bla bla... I suppose to access my website from outside of the network by entering http://MyPublicIp:80 in a browser but I couldn't accomplish this task by now despite using godady's domain forwarding tool,I see a small view of my website when I click the "preview" button that checks whether the address(http://publicip/Index.aspx) I entered where my domain will be forwarded is available or not. I am sure that configuring domain does not play a role in solving such a problem since using public ip and port matching does not help. So here is the first question, What is the fact that I face this problem? After that, I have couple of question regarding domain forwarding using godaddy tool. Can I forward my domain to a any port for example port 8080 other than default http port 80? Additionally, can I use a sub-domain to forward to a different port of the host? What I want to design is if the client enters www.mydomain.com, website1 will respond over a specified port and after when a client enters info.mydomain.com, another website which listens on different port will respond. I tried to add a sub-domain and forward it to a address like http://www.mydomain.com:8080/Index.aspx with no success. Can I really do that? Finally, what if I have a ftp site listening on the default port 21 and I create a domain like ftp.mydomain.com that will forward to that ftp site address. Is it possible to use sub-domains for ftp site access? I know I am more than confused but no matter whatever and however you reply to me, you will help me have a more clear view on this subject. Thank you very much from now.
