Flush IIS HTTP and FTP Logs to Disk

Today I wanted to find a way to flush the IIS FTP logs on-demand.  The logs for IIS FTP flush to disk every 6 minutes, and the HTTP logs every 1 minute (or 64kb).  This can make troubleshooting difficult when you don’t receive immediate access Read More......( read more ) Read More...

Changing the Identity of the FTP Extensibility Process

Many IIS FTP developers may not have noticed, but all custom FTP extensibility providers execute through COM+ in a DLLHOST.exe process, which runs as NETWORK SERVICE by default. That being said, NETWORK SERVICE does not always have the right permissions to access some of the areas on your system where you may be attempt to implement custom functionality. What this means is, some of the custom features that you try to implement may not work as expected. For example, if you look at the custom FTP logging...( read more ) Read More...

How to use Managed Code (C#) to create an FTP Home Directory Provider that is based on the Remote Client IP Address

I recently had an interesting scenario that was presented to me by a customer: they had a business requirement where they needed to give the same username and password to a group of people, but they didn't want any two people to be able to see anyone else's files. This seemed like an unusual business requirement to me; the whole point of keeping users separate is one of the reasons why we added user isolation to the FTP service. With that in mind, my first suggestion was - of course - to rethink...( read more ) Read More...

How to determine if FTP clients are using FTPS

One of my colleagues here at Microsoft, Emmanuel Boersma , just reminded me of an email thread that we had several weeks ago, where a customer had asked him how they could tell if FTPS was being used on their FTP server. He had pointed out that when he looks at his FTP log files, the port number was always 21, so it wasn't as easy as looking at a website's log files and looking for port 80 for HTTP versus port 443 for HTTPS. I had sent him the following notes, and I thought that they might make a...( read more ) Read More...

How to Use Managed Code (C#) to Create an FTP Home Directory Provider for the Days of the Week

I had a question from someone the that had an interesting scenario: they had a series of reports that their manufacturing company generates on a daily basis, and they wanted to automate uploading those files over FTP from their factory to their headquarters. Their existing automation created report files with names like Widgets.log , Sprockets.log , Gadgets.log , etc. But they had an additional request: they wanted the reports dropped into folders based on the day of the week. People in their headquarters...( read more ) Read More...
