I'm monitoring a directory for FTP uploads on the server using a CF event gateway. Fine so far, but I want to get at the IP address of the computer uploading the file. The server is Windows Web Server 2008 R2 IIS 7 and Windows FTP 7.5
What I am aiming for is growl type message if the uploaded file has been handled correctly (or else error msg) and for that I need the IP of the sender. (there is no problem with NAT within the LAN)
The FTP service writes a log containing the IP which I could try to correlate with the directory monitoring event, but other than by scraping the log is there another way?
Since ColdFusion has no connection to the FTP service in IIS, you'll have to handle this through the logs. You can, however, use something like LogParser (see this article
from Ray Camden on how to use it to parse an IIS log file.
Good luck!

For network gurus out there, I'll like to ask some questions regarding some unique setup where the server will be sending a request to a client on localhost on a certain port.
I have a cloudy understanding of some network fundamentals that I hope you'll be able to help me out.
Kindly check the image below:
Basically, there's a static website hosted in AWS s3 and at some point this website will send a request to https://localhost:8001.
I was expecting that it will connect to the nginx container listening on port 8001 in my local machine, but it results in 504 gateway error.
My questions are:
Is it possible for a remote server to directly send data to a client at a particular port by addressing it as localhost?
How is it possible for the static website to communicate to my local docker container?
Thanks in advance.
In the setup you show, in the context of a Web site, localhost isn't in your picture at all. It's the desktop machine running the end user's Web browser.
More generally, you show several boxes in your diagram – "local machine", "Docker VM", "individual container", "server in Amazon's data center" – and within each of these boxes, if they make an outbound request to localhost, it reaches back to itself.
You have two basic options here:
(1) Set up a separate (Route 53) DNS name for your back-end service, and use that https://backend.example.com/... host name in your front-end application.
(2) Set up an HTTP reverse proxy that forwards /, /assets, ... to S3, and /api to the back-end service. In your front-end application use only the HTTP path with no host name at all.
The second option is more work to set up, but once you've set it up, it's much easier to develop code for. Webpack has a similar "proxy the backend" option for day-to-day development. This setup means the front-end application itself doesn't care where it's running, and you don't need to rebuild the application if the URL changes (or an individual developer needs to run it on their local system).
I have two EC2 servers. One runs Windows Server 2012 R2 and the other runs on Amazon's Linux build. The Linux box is used as a web server with PHP doing the scripting. I would like the Linux server to send a string to the Windows server every time a PHP file (acting as a RESTful end-point) is processed.
I've never done anything similar and was wondering where to start. From the research I've done so far, it seems like using Netcat to create a Telnet connection might do the job. If so, what would the boilerplate code look like? Netcat is a pretty old platform and there's not much to be found in terms of examples from a Google search.
I am also open to other solutions that could solve this problem.
The workflow of what I am trying to do looks like:
A user hits PHP file end-point -> PHP or the server it runs on sends a string to the Windows Server -> Windows server receives the string and starts a script
You could think of exposing this as an endpoint on your Windows server using either of:
IIS + PHP
IIS + CGi/Perl
IIS + Asp
or anything else.
Expose a simple page on IIS (Windows web server) and hit that from within your webservice login (Linux server) whenever the Linux server receives a request. The script/page that is exposed by your Windows server could execute the desired script then.
The page/endpoint that is exposed on the Windows server should be protected so that not anyone could execute it (disabling public ips. Restricting only the Linux server Ip in your firewall rules etc.)
Sample
Within your php webservice - $my_var = file_get_contents('http://WinServerPrivateIp/runScript.pl'); // Make it asynchronous if needed
runScript.pl in Windows - Would execute your actual script.
You could look at calling winexe from within PHP. I haven't done it myself but I've read that this should do the trick.
winexe Sourceforge
Some sample code from within PHP here
I hope that this is of some help to you

I have ColdFusion 9 installed on my system.
I need to read data from an SSL encrypted site (https). I have followed all the steps described in CF documentation.
That is:
Go to a page on the SSL server in question.
Double-click the lock icon.
Click the Details tab.
Click Copy To File.
Select the base64 option and save the file.
Copy the CER file into C:\ColdFusion8\runtime\jre\lib\security (or whichever JRE ColdFusion is using).
Run the following command in the same directory (keytool.exe is located in C:\CFusionMX7\runtime\jre\bin):
keytool -import -keystore cacerts -alias giveUniqueName -file filename.cer
In CMD, it showed "certificate was added successfully"
But it is still showing the same error peer not authenticated.
Is there anything more required?
If you are trying to call web services in CF 11 (and maybe 10 but check that yourself), CF expects the web service or any CFHTTP call to use the WebSocket Service and port 8577 in a standard setup. This is because the WebSocket Services have been optimized for web services and CFHTTP also uses WebService Sockets.
I run CF 11 on my IIS server and port 8577 is blocked by a firewall. When I tried to connect, it sends back this error for CFHTTP and web services:
"I/O Exception: sun.security.validator.ValidatorException: PKIX path
building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to
find valid certification path to requested target"
It would seem like it requires adding custom certificates to the CACERT for JRE, but that is not the solution for me.
There is a simple fix to get this running with IIS (at least IIS) if you do not want to unblock the WebSocket Service and you don't need that performance to run natively. All you have to do is go in to the CF Admin dashboard and change the WebSocket Service to "Use Proxy". This will send all calls to the CF WebSocket Service or CFHTTP through IIS as a proxy. Restart the CF Application Server service and it should work just fine. If these directions are not perfect I apologize but it will lead you to get it working. See also Using WebSocket with ColdFusion 11.
Although the documentation doesn't specifically mention it, restarting the ColdFusion service is required. If you haven't already, that should be the first thing you try.
when i try opening http://127.0.0.1:8500/test.com
I get
500 There is no web application configured to service your request There is no web application configured to service your request
when i try opening http://127.0.0.1:8500/CFIDE/
I GET THE same error
Kindly guide me to solution.
It means the server did not fully start. The JRun container started and was able to accept an HTTP Request via its internal webserver port, but then the ColdFusion Server inside JRun was not fully deployed or not deployed at all.
The startup events in /path/to/coldfusion8/runtime/logs/coldfusion-event.log and /path/to/coldfusion8/logs/server.log will contain details about what failed during ColdFusion startup.
You will probably not make sense of the events as they are usually somewhat cryptic. Please post log contents for further diagnosis.
I am trying to call a web service from a BizTalk (2006) orchestration.
Having got the hang of the basics, I have been following this tutorial (page 74 onwards) in which i have a web reference to an external web service (I am using this web service instead of the one in the tutorial), I have my web message in a Send component, and have set up the request / response ports for the web service call.
I'm fairly sure that eveything is set up correctly, but my orchestration fails to call the web service with the following error:
The adapter failed to transmit the message going to send port
"My_Order_Processor.Orchestration-CurrencyConvertPort-36c122f41c5596ae"
with URL "http://www.webservicex/net/CurrencyConvertor.asmx.
WebException: Unable to connect to the remote server.
SocketException: An existing connection was forcibly
closed by the remote host 209.162.186.60:80
The IP 209.162.186.60 is the address for the web service I am trying to connect to. I am trying to narrow down the reasons for the error, e.g.:
Firewall issues
Proxy server issues (I don't know how to configure BizTalk to use a proxy server)
Something else
The BizTalk server can ping the web service, I can access the internet (through IE), I can add the WebReference to the project successfully (meaning at least the orchestration designer can access the web service okay). I have also tried a different web service, with the same result.
Any ideas on finding out why this is happening or how to find out more info? (I'm new to BizTalk)
I've seen this veru vague error before for many different reasons. Two suggestions.
Download something like NetMon and watch what is going on on the wire.
Turn off chunked encoding. For some reason, many web services don't handle this well.
Let us know what you find out.
Could this not be an authentication issue? Check that you can connect to the webservice using the Bts credentials.
This turned out to be a proxy issue.
By navigating to Biz Talk Group -> Platform Settings -> Adapters -> SOAP, I was able to configure the BizTalk server host's SOAP adapter (which is what the web service call uses to make the call) to use our company proxy server correctly. Double click the 'send' SOAP adapter, go to Properties under adapter name.
