PIX 501 in the firewall of the Web server
Hello
At the suggestion of a colleague, we bought a firewall PIX 501 to protect our new Win2003 web server and a UNIX/Oracle DB server.
I've never worked with before firewalls.
Our servers are located in a cage at the ISP and belong to us. There are only two servers providing web site. I have read the documentation in the Getting Started book and it does not answer my question.
We have 2 web sites with different IP numbers on our web server. Let's say 140.5.5.4 and 140.5.5.5. I understand that I have will redefine the numbers with the firewall (192,...) but I do not understand how the routers at the ISP will be able to route requests for two websites to the firewall when it has one IP number, say 140.5.5.1?
Any help is appreciated.
Thank you, Jerry
Jerry,
what you are referring is called port forwarding. Whether you a PIX with a public IP address 12.1.1.1 and your web servers are respectively and 12.1.1.2 12.1.1.3. Port forwarding is really a 2 step process:
* a static translation of the public IP address of the PIX (12.1.1.1) at the address of the web server (12.1.1.2)...
static (inside, outside) tcp 12.1.1.1 12.1.1.2 www www netmask 255.255.255.255 0 0
* an intermediate statement basically "all web requests should be allowed in the pix outside of the interface"...
driving permit tcp host 12.1.1.1 eq www everything
Here is a link that will help you to clarify this point:
www.Cisco.com/warp/Customer/707/28.html
This should help you get started. Regarding the basic configuration, it takes config examples on the Cisco site, if you have access CCO.
Let me know if it helps.

PIX 501 problems with the web server internal.
I want to open for my internal Web server, so it can be accessed from outside and I read about it here and how to do it and I do what I think of his right, but I can´t operate.
Now I just tried to open the http port standard 80 but later I want to open a specific port and also use SSL on the web server for added security.
Then I would like my setup now get help and also how to do when using other ports and SSL later.
Thanks Thomas!

PIX with H &; S VPN DMZ hosting web server to the hub
Ok
Heres a problem which I think would be quite common for these even remotely conscious of security. Unfortunately, my knowledge of the PIX (as well as other Cisco devices) is still in phase of 'growth '.
So, here's the problem. I have a WAN put in place with PIXen and SonicWalls, we are set up in a design essentially Hub and Spoke (fine ok so it is partially meshed). We recently decided to pull the trigger on getting a 'real' web site and everything went relatively well that getting up and rolling. (even with my notice of 3 days/deadline), but here's the problem: I set up the web server on the DMZ to the hub pix, and I figured out (the easy part) how to set things so in the Home Office, people can connect to the web server by using the internal address, but I don't know what to do for people in remote offices with VPN home connections. I tried to define static routes, I tried to add the DMZ to the VPN trigger, I tried to do both of the last things together, and I checked that I have rules allowing traffic to the VPN outside the DMZ on the inside. So, what else can I I get?
I have no problem by configuring a PIX for all basic ups and VPN even at this stage, I can do most of it through the CLI (even if I still want to do more through the PDM). My biggest stumbling block on the PIX has so far was when I actually involve this pesky DMZ...
I actually two PIX in my office, two for my network domestic (one for my place in the States and one for my place in the Japan), so if you can help me, I'll be the two problems and do not forget to give a rating of excellent reviews!
so I guess that leaves me to the place where I scream...
Help!
and I humbly await your comments.
the current pix configuration should look at sth like this,

isakmp policy 10 hash md5

now, to add dmz on top of the existing vpn, add the following to the pix (and apply the same concept on the remote end device)
access-list 102 permit ip
access-list 110 permit ip
nat (dmz) 0 access-list 102

External HTTP >; internal to the web server
Hello
I have a router ADSL with a public IP assigned, preforming NAT. This leads to a 506th PIX which leads to a Web server. The entire interior of the ADSL is on private IP addresses.
I want to allow external users access to the Web server on port 80.
I inwardly and outwardly put up ICMP connectivity (for testing only) and it works correctly.
I created a virtual server on the ADSL router that forwards port 80 traffic to the external interface of the web server. It has worked successfully for half an hour and then something in the config changed PIX and it no longer works. Here is my config PIX

Just upgraded to 8 Captivate and for some reason my server any internal messages is no longer work on the web server. I can test locally the lesson that always points to the Web server and it works. Can't understand why when it is on the server it does not work. The ashx handler that manages to post is fully accessible to the web server and DNS solves very well so I can't understand why he doesn't hit the Manager. I use IIS to host it and a .ashx for managing for results.
Is there maybe something new that needs to be allowed in IIS for 8 Captivate work? .js seems to be fine and firewall is not the issue. Short of ideas and the need for this work as soon as possible.
Thank you very much for your help!
Nick
OK, finally solved. For some reason any run under HTTPS lesson could not publish my results. As soon as I changed to HTTP the results perfectly. All of this makes sense why I could post locally on the Web server. Hope this saves someone else 5 days of hell.

Not possible to activate the scripts on the Web server
Hello
I would like to create a page .html for Web with a bit of scripting ESP included - Services because now I understand just this:
<% for (i=0; i<3; i++) {
...some text...
} %>According to this document NOR, I first need to enable scripting:
To use the script with a Web service, you must enable the feature on the Web of LabVIEW server. In LabVIEW, select the script on the Web Server: Configuration page in the dialog box Options to enable the use of scripts on the Web server.
I activated the Web server and it works OK. But there is nothing called "Scripting" in the configuration page - and the script is executed (the code is just printed in the form of simple text).
Anyone know how to activate the ESP script?
Version: LV 2012.
Best regards, Jan
Hi Jan,
In fact, you use the ESP file instead of a static HTML file. For example, if we had the static html file:
Hello world
This file can be located at something like /MyWebService/HelloWorld.html.
If I then do something like have a page to say "Hello, Jan" or "Hello, Mark" I could use ESP. In this case, your code might look like:
<>
var xname = form ['name'];
%>
Hello, @@xname
The URL of such a web method is perhaps something like jan/MyWebService/Hellovar/Jan where Jan string literal passed to the terminal of a web method that can resemble
In this example, the string "Jan" is passed to the terminal of the value of the VI. What implementation of the Web method in the spec to build his signature might look like in /Hellovar /: value.
So, back to your original question. You embed not ESP breast and the HTML document. Instead, you embed HTML inside a document of ESP and the rendering of the document in HTML format when accessing the URL of the Web method. While the paper you mentioned earlier has an example project in that you can use as a reference
-
Here's a question I'll get lucky with. I have a VI, set to be reentrant, broadcast via the web server. The main instance of the VI is never worked with: it's a clone whenever someone accesses the correct URL, and the user interacts with the newly created clone (never the main forum). A clone is able to configure and calling instrument VI when good IDs are entered, which translates to browser popups that are controllable on the end of the user (even if only one user ever does both. To clarify, many clones can be opened simultaneously for connection purposes, but that a user never interacts with the instruments that are not themselves reentrant).
If the user clicks on my Logout button in their browser, it is trivial to close these instruments other, independent and properly clean. But if the user simply click on the red X in their browser, it is non-stop and the instruments that the clone called stay open on the server, when they close.
My experience so far:
No close panel? event seems to be triggered in the clone. The clone simply cease to be.
The remote_panel_connections property doesn't seem to work properly in this case (I have not had luck so far), since it is possible that more than a clone to be active and that the main parent who is spawning clones stays running, but is not interacted with in some way.
What I need:
One way for the clone of VI recognize that the user has closed his browser and communicate that it closes all the assets of VI before ending.
--------------
I would like to avoid forcing the instruments that the clone call to constantly query to see if the VI clone is present on the network. If there is no other solution, but this, I would appreciate a suggestion as to the intensive way less code and resources to implement this type of interrogation, as the instruments are really designed to be totally independent after they are called, rather than under vi.
Thanks for all comments, let me know if you need more information.
MTdev wrote:

When a VI stops running, any reference as a queue is also cancelled. You can make use of this fact. If your original clone VI could launch a second reentrant VI, which remains active, you could channel all communications to the instruments via VI second using a queue created in the first. When the first VI disappears, it will trigger an error waiting waiting VI in the second (no vote office is involved). The second VI can take all the necessary measures.

start the Web server in different folders
I developed a compiled VI (Smarts - Net .exe) that has been designed to operate in a specific folder (\Smarts-Net) and activated the Server Web page of Smarts - Net .html in the same folder. So far so good.
The application receives data in real time produced another of our programs and generates graphs to show "what happens".
My clients would like run multiple instances of my program for their customers, but want to isolate their customer 'A' customer 'B' so that they cannot display the data on the other. I can start my application using different IP ports so that I can have multiple views, but I want to further isolate the data of the customer in different folders.
I did a 'manager' program that will create a subfolder of the folder in my main application (\Smarts-Net) so that it would appear as "\Smarts-Net\JobA" and copy all the files in the main folder in the new subfolder. I then change the of Smarts - Net .ini file with the new pathname of the file and the new port like this number:
[Smarts-Net]
server.app.propertiesEnabled = True
Server.OLE.Enabled = True
Server.TCP.servic = "My Server computer/VI"
server.vi.propertiesEnabled = True
WebServer.DirectoryIndex = "index.htm"
WebServer.LogEnabled = True
WebServer.LogPath=C:\Smarts-Net\Logs\Smarts-Net.log
WebServer.MimeTypes = (a LOT of Mime types in here... I left aside for this post)
WebServer.Port = 9501
WebServer.Enabled = True
WebServer.RootPath=C:\Smarts-Net\JobA
WebServer.TcpAccess = "" + c * ' "
WebServer.ViAccess = "' + * '"
DebugServerEnabled = False
DebugServerWaitOnLaunch = FalseAfter you change the .ini file, I start the application (Smarts - Net .exe) to the new folder.
This is where I need help. If I try to display the VI from another computer using an address like http://snape:9600/JobA/Smarts-Net.html, I get an "HTTP 404 - File not found" error. But, if I try to http://snape:9600 / Smarts - Net .html, I get the VI Panel!
Thus, it seems that I can change the Port in the .ini file, but not the RootPath. Does anyone know how to get the html to load from a different folder from the one specified when I created the application code?
Hello Steve,.
From your description it looks that the web server is already doing what you say you need for.
There is a difference between the URL path, the path that is entered in the browser and the path of file system, the location of the file on the disk.
The WebServer.RootPath token specifies the directory of the file system that corresponds to the root directory, "/", in the URL. You have specified C:\Smarts-Net\JobA as root your path so all files in this directory will be the URL of the http://mycomputer:myport / myFile. If you want the URL of http://mycomputer:myport/Logan/myFile then you need to have your root C:\Smarts-Net\ directory.
Does make sense?

Additional installers do I need to use the web server?
I am building an application in LabVIEW 8.6 and want it includes the Web of LabVIEW server and eventually Web Services. Should additional installers I include? In addition to the runtime, the following options are: 'LV Web Services', "NI LabVIEW Run-Time Engine Web Server", "NI LabVIEW Web Server." I can find no documentation explaining the differences between these - especially the last two.
Hello Nathan,.
From 8.6 web server is a separate component. Just as LabVIEW desktop is a separate installation program since the runtime if there is a web server for each component. In addition, Web Services is a component that is generated on the web server.
So, if you need web server in the Office two, LabVIEW and RTE and you eventually will need to deploy web services, as well, then you'll need to install these components.
Here's our FAQ to get Web services work - you might be useful.

What is the web server integrated for Windows XP Professional?
Hello
I would like to know what the web server integrated for Windows XP Professional.
I don't know of a free web server like Apache or IIS.
I want to host my site on the net using the web server integrated in XP (not IIS).
Thanks in advance.
It is not just any server web, other than IIS, integrated with Windows XP Professional.
You think perhaps of Personal Web Server (PWS) which was part of the old operating systems like Windows NT. Which no longer exists in Windows XP Professional - it has been replaced by IIS.

WANT to 114 does not connect to the Web server
Have installed a 114 WANT, everything works except for the webservices - wireless eprint etc.
I tried everything-
1 re-install services - error cannot connect to the web server
2. Update - error cannot connect to the web server
3 give the static IP address
4 restore the default settings
I have an internet connection on all computers. Can someone give me a hint on how to get Web services to work?
Hi sbenzie,
How your printer is currently connected to the network? Via Ethernet or wireless? What is your current router / network configuration? That shows your printer because it is the IP address? What happens when you try to launch applications?
Not yet given the information above, here's what I would try.
I suggest to reconnect the printer to the network by running the Wireless Setup Wizard and attempt to restart the web services. If this is not enough, you may change some DNS settings in printers EWS (built-in web server) to do this, put the IP address in a browser window on your PC.
This should start the integrated Web server. In SAP, select the network on the network tab, select 'network '.
Then select "network address" (IP). Do not change the IP configuration at the top. Go down under "DNS address configuration"and select 'Manual DNS server'. " Under manual DNS server, enter (an 8 in each box on the first line) 8.8.8.8 and 8.8.4.4 on the second line. Press the button 'Apply' at the bottom.
Now try to connect to Web Services again.

I can\ to connect to the web server integrated on my D7460?
Hello
I had some problems with my Photosmart D7460 printer and resolved (for now) most of them.
Except that I can't connect to the built-in web server. Also, I do not get a response when I try and ping the printer.
Giving to think I have problems of network with the exception that I can print to this printer... Well well, from most of the computers on the network, but that's another story.
I checked what the said road IP address he gave to the printer.
Any suggestions would be welcome.
OK, I seem to have solved the problem.
I'm not sure that bit of material, it was causing the problem but it seems to come form tries to use "WPA & WPA2" parameters (BT Home Hub 3.0) wireless access point.
Who having spent 'WPA only' I can now ping, print and connect to the web server.
