Web Server - Ask For Help / Web server hangs during no apparent activity
« on: January 25, 2012, 05:19:59 PM »
Using v 4.53, have a web server that has been running without issues for months. About three weeks ago the client says it stops working several times a day and they have to reset the server because the web server is running as a service. The server is a Godaddy virtual server.
I've been monitoring it with logging and a utility that requests a small test page every 5 minutes and running the server as a desktop app on the VDS for testing. It is hanging. I check my logs and there is no apparent activity at the time it hangs. When I run it on the desktop I see the app on the task bar, but the visible window has vanished and I have to kill it. It happens regularly at night, but not at the same times. The couple of packet sniffers I've tried to install won't work on the virtual server, they need a nic.
Couple of questions: Is there a packet sniffer that will work on a VDS so I can see everything that is coming into the web server? Or can I trap/log the data/request in NetTalk before it does anything with it? The first place I'm trying to do stuff is in the WebHandler ProcessLink embed.
At this point all I can think is that my web server is being queried by a web spider or probed by some bot. Any advice would be appreciated.

Web Server - Ask For Help / Hand coded report to PDF?
« on: June 14, 2011, 09:38:39 AM »
I have a need for a hand coded report that I want to go to a PDF, then serve and allow the user to view/download/save the PDF. I can make the Clarion report procedure and the steps with NetWebReportABC work as a test. But the report is not suited to the report procedure as I have a lot of extra pages of text and images, and many formats of detail lines that are conditionally used. I also need a footer from page 2 on that shows Page XX of XX, and I don't want the user to be able to edit the PDF.
Can this be done? Is there another tool that I can use that will convert a hand code Clarion report to a non editable PDF that I can then use standard NetTalk stuff to serve back?
This is currently an end user app that generates an RTF file that gets loaded into a VB TX Text Control app. It handled all the images, page footers and some protected fields. I've tried a few rtf to pdf converters, but none of them have worked well, and I'll need the images embedded now. They are just links in the RTF. Now we are trying to make this a web based app and I still need to produce the same complicated report, but in PDF. I can do everything with a hand code report easily enough, except for the Page XX of XX, and then making the PDF from it.
Any ideas, or if you can point me to some tools that can do this, would be greatly appreciated.

Web Server - Ask For Help / Want to serve a file from a variable name on NetWebForm
« on: March 11, 2011, 02:32:26 PM »
Using NT 4.53. I want to serve a file on a NetWebForm from a variable. I think it should look like this:
<pre>
<!-- Net:f:<!-- Net:s:FileLink2 --> -->
</pre>
NetTalk gives me a file not found, then the text of the session variable, and the rest of the page. So it knows I want a file, but doesn't use the session variable as the file name. Is there some way I can do this? It looks like the Net:f: has to be a fixed file name? Is there some other way this can be done with a simple statement similar to the above?
Right now I get by with calling a proc and reading the file in line by line and using SendPacket. It works, but thought there should be something better. Thanks!

Web Server - Ask For Help / POST problems
« on: January 19, 2011, 11:15:28 AM »
Using NT 4.53. I've had an ongoing problem that I would like to get fixed. I am POSTing to two separate websites (PayPal and UPS) and most of the time everything works. I POST, I get the return data, life is good. But occasionally I POST but I don't seem to get anything back. All of these POST's have something to return and the servers I'm posting to get the request and swear to me they are sending the response. I log my request and as soon as I get a response I log it. But there are times, especially with UPS, my log shows the request but no response. When I log into UPS, the data I should have gotten shows 'read', like they sent it, but I didn't get it. This has just been a nagging problem that I've tried to work around, but would really like this to work consistently. Any ideas as to what may be going on or something I should do differently? Thanks.

Web Server - Ask For Help / Web server as service issue
« on: September 21, 2010, 08:06:29 AM »
Currently running NetTalk v4.53, SelfService v2.05, and WinEvent v3.32. When I was using NT v4.3 and the other tools the web server ran as a service fine, no issues. Now that I am running NT v4.53, it does not seem stable. Twice in the past two days the server has "stopped" and going into the Admin tools | Services, it is NOT running. It is set for Auto in properties. Any ideas of why the server is now stopping and has to be manually restarted when it used to work fine? Thanks.

Web Server - Ask For Help / Problem with image/link after upgrade to 4.53 (and more)
« on: September 06, 2010, 10:22:19 AM »
I upgraded my NetTalk from 4.30 to 4.53. Now I have 3 problems.
Problem 1:
With an image/link on a NetWebForm. One of my fields was an image that pulled it's graphic from an external web site. It worked before but not now. The generated source from the web page is different:
Before, with 4.30:
<div id="securecheckoutbuttons_loc__img1_value_div" class="adiv">
<a href="ppGetPhone" target="_self" title="" ><img src="https://www.paypal.com/en_US/i/btn/btn_xpressCheckout.gif" width="" height="" alt="" border="0" align="absmiddle" ></img></a> <a href="ppGetPhone" target="_self" ></a>
</div>
After, with 4.53:
<div id="securecheckoutbuttons_loc__img1_value_div" class="adiv"><a href="ppGetPhone" target="_self" ><img src="https%3A//www.paypal.com/en%5FUS/i/btn/btn%5FxpressCheckout.gif" width="" height="" alt="" border="0" align="absmiddle" ></img></a> <a href="ppGetPhone" target="_self" ></a>
</div>
The image does not display and there is nothing to click. The new code is using codes in place of the colon and underscore in the URL for the graphic. What is the problem with this and how do I get it fixed? Thanks.
Problem 2:
I'm also having a problem with the Firefox browser opening the main frame when it hits the site. I get my header and menu on the left, but the right side frame gives this message:
Firefox can't establish a connection to the server at www.missouriauctionsupply.com:0.
Though the site seems valid, the browser was unable to establish a connection.
* Could the site be temporarily unavailable? Try again later.
* Are you unable to browse other sites? Check the computer's network connection.
* Is your computer or network protected by a firewall or proxy? Incorrect settings can interfere with Web browsing.
I can use the menu on the left after getting the message, I can log in, and when I log out, the browser displays what should be there to begin with. But it's not coming up when I first try to open the site. Internet Explorer seems to initially load the first Frame fine, but if I refresh, IE just shows a blank window. Viewing the source shows the frame stuff but nothing gets displayed on a refresh. What can I do to have this work like it used to?
Problem 3:
Every once in awhile I get the following from Firefox:
An error occurred during a connection to www.missouriauctionsupply.com.
SSL received a record that exceeded the maximum permissible length.
(Error code: ssl_error_rx_record_too_long)
The page you are trying to view can not be shown because the authenticity of the received data could not be verified.
* Please contact the web site owners to inform them of this problem.
I got this in the older version too. I was hoping the upgrade would fix this, but it has not. Any ideas on what this is and how it can be avoided? This just happens from time to time doing the same stuff over and over. Most of the time all the steps work properly, other times I'll get this message.

Web Server - Ask For Help / Issue with email not always getting sent
« on: June 18, 2010, 08:10:23 AM »
Using NetTalk 4.30, I have an issue on my web server where e-mail is not consistently getting sent. The app is a web store, they are all secure pages. In the last step I have a NetWebForm where I have embeds in Generate Form | 1 Start, and Generate Form | 9 After </script>. The first embed has a call to a local routine Do CreateNewOrder, where quite a bit of stuff is going on with writing the order to my files updating daily summaries and so on. The second embed is the call to my e-mail window: OrderConfEMail(loc:emailto, loc:emailtext, loc:emailhtml,0,0). Most of the time this all works fine.
However, there are times where I am not getting the confirmation e-mail, but I do have the order written. The way it is coded is that if there is an order written out, the e-mail code will execute. I should always get an e-mail on an order. I originally had the call to the e-mail in the same embed, the 1 Start, but it worked even less regularly then, so I moved it to the end of the Generate Form embeds and it has worked better. But I need it to work all the time.
First, why does this not always work? What else can I do to ensure the e-mail will always be sent? I am going to add code to the ErrorTrap of the email window and see if there is something getting posted there, but wondered if anyone had anything like this and what you did about it. It seems like there is some sort of timing issue that I can't nail down. Thanks.

Web Server - Ask For Help / Users security settings blocking my page
« on: February 08, 2010, 10:27:45 AM »
I have an issue where sometimes a user cannot get my page to come up. Here is how the client described the issue:
"This morning an IT officer from a bank called an explained the issue to me. He said that when the screen for the login and password pops up, it is identified only by an IP address. Apparently, security settings block such IP identifiers because of fraud, etc. It seems that instead of the IP we need to have an identifier show there..."
I'm not sure what to do with this. I am using v4.30. My web server is sitting on a godaddy VDS. The login page is called by my client using http://ipaddress/LoginForm. There is no domain name associated with this particular IP, though I suppose there could be if it would help the situation. Please let me know if that is the solution or if I need to do something in my web server to return some other info in place of the IP number. Thanks much.

Web Server - Ask For Help / User experience with IE not working all the time
« on: July 14, 2009, 09:40:08 AM »
I have some users with Internet Explorer issues that I can't duplicate on one of my NetTalk sites. Below is the latest text from one of the IT people of this user. What can I do with my NetTalk site that will work around this? Any ideas appreciated. Thanks.
Brian Ekeland
I have tested this in the following manner
1. I logged in as a network administrator to her PC and then logged into the site using her credentials. In this case, I was able to login successfully.
2. I then tried logged in as her on the PC. This time, however, the login attempt to the site failed with some sort of Java error (Object Unexpected, line 50).
3. So then I made Sam’s account a Power User on her computer but the results were the same as #2.
I’d appreciate any assistance your technical people can provide to this. It currently appears to be some sort of permission issue with the user’s account on the PC but all of her other applications work fine and her web browsing works fine to other sites. Please also be aware that granting our users full administrator rights to their PC is not desired and is frowned upon by our auditors so any other work around or fix though is fair game.

Web Server - Ask For Help / Can NetTalk Client do HTTP Digest Authentication?
« on: May 28, 2009, 07:18:01 AM »
I have a need to access a device that uses HTTP Digest Authentication. It is a network camera. My normal tool for this is Catalyst Socket Tools but they don't support this in any flavor of their stuff. So looking for alternatives and thought maybe NetTalk might be able to do this. Is that a possibility or anyone know of a TCP/HTTP tool that can do this? Thanks much.

Web Server - Ask For Help / SSL Certificate issue
« on: May 27, 2009, 12:35:37 PM »
I'm using a Starfield SSL Certificate that we got through Oak Park. When I use Internet Explorer, everything is fine. When I use Firefox I get a certificate error, Unknown Issuer. I talked with Starfield tech support and they say that my web server either does not have the intermediate certificate installed or it is not serving it properly. I asked why does it work with IE and they say that IE is more forgiving. I don't know what to do with this. I need NetTalk to use this certificate properly so I don't get these kinds of errors in Firefox. All I've done is go through the steps in the NetTalk docs to make the crt and key files and have them in the web\Certificates folder.
The web site is www.aucsupply.com. The error in Firefox will come up when I click the Login button. Please give me some direction. Thanks.

It hits my server app and the browser displays the image. When I use this:

I get a 400 Bad Request, The requested file was not valid. The file is there, I just want the browser to come up with the standard Save/Run dialog. I want this under a button on a form and was trying 'downloads/appnav44full.exe' as the URL and I get the same 400 Bad Request.
What do I need to do differently to get this file to download to a user? Thanks.

I have a client trying to use a Blackberry to access a web site I used NetTalk 4.30 on. They say they can see the form, but can't do anything with it, can't type anything in. My client is asking me to make this web site mobile friendly. Do I need to upgrade to v4.31? Can I add something to my existing 4.3 to make this work? Any direction would be appreciated. Thanks.

Web Server - Ask For Help / E-mail issue with html codes
« on: April 03, 2009, 10:13:22 AM »
I have an issue where I post a request to PayPal and they return some data, one of the items being an e-mail address. The e-mail address comes back like this: EMAIL=myaddr%40att%2enet and that works for me all of the time. However, there are e-mail addresses with a double period in them and I get this from PayPal: EMAIL=theemailaddr%40stny%2err%2ecom. When I use the GetSessionValue on the EMAIL, I get "theemailaddr@stny rr.com" There is a space in place of the first %2e. So I end up with an invalid e-mail address.
I am still running NetTalk v4.30. Has this been fixed in the latest version? Or is there some sort of workaround? Thanks.

Web Server - Ask For Help / NetWebForm generation timeout?
« on: November 03, 2008, 01:56:06 PM »
I have a NetWebForm and am using the Generate Form | Start embed. In this embed I call a window that communicates with PayPal by posting a string and receiving a response. When that returns, the NetWebForm should come up with my order confirmation number. I am having an issue where it is like the NetWebForm does not complete it's generation. Maybe the response from PayPal takes too long and the NetWebForm stops? Is there some timeout issue in there that can be extended? This is not a session timeout issue. Most of the time this all works. A couple times a week this comes up where I've sent my query to PayPal in this embed, but something kills the NetWebForm to where the rest of my code that completes the order and displays the confirmation just doesn't happen. I am communicating with PayPal and they are blaming my server and a timeout. Is there any sort of timeout on a NetWebForm generating? Thanks much.
