Every once in awhile I hit a (technical) wall, stumble upon a great tool or look for a reason to improve my English.
This is my place to share, welcome to my logs.
I prefer to use FileZilla FTP Server above the traditional IIS FTP module. FileZilla comes with a lite and lean GUI, great logging tools, connection (speed)limits and more. If you do not know FileZilla Server or the Filezilla Client I strongly encourage you to try them out at https://filezilla-project.org/
Setting up the FileZilla Server is straightforward, but after configuration the user/groups and directory you can have some trouble setting up the Windows Server 2012 Firewall. Traditional FTP uses port 21, you should open this on your Firewall (see below) but even after opening up this port some errors can rise to the occasion when using passive ftp.
I had the following problem:
Response: 227 Entering Passive Mode Command: LIST Error: Connection timed out Error: Failed to retrieve directory listing
When port 21 is configurated in the Firewall, and you have setup the users/groups in the FileZilla Server setup you still can encounter the problem above. By default the FTP client will connect through
passive mode, and opens a random port between 1-65535. Now this is a wide range and I do not recommend opening all these ports. Instead you can limit the range of these ports to let's say: 50100-51100.
Passive mode settings.
Use custom port rangeis checked and enter
50100in the first box a and
51100in the second.
Now that you have finished setting up the custom port we can move forward to the Windows Server 2012 Firewall.
Lets open up the Firewall panel, press the Windows key on your keyboard and start typing
firewall. The result should be
Windows Firewall with advanced.... Click it or hit enter.
(Pro tip 😉 hit
Windows Key + R →
firewall.cpl → hit
Portand click next.
50100-51100in the Specific local ports field.
Nextand make sure the
Allow connectionoption is selected. Then hit Next again.
Passive FTP Ports - FileZilla.
In case you have not yet added port 21 to the Firewall you can use the same steps, but instead of using port 50100-51100 just use port 21.
When connecting to your FTP Server the result now should be:
Response: 227 Entering Passive Mode Command: LIST Response: 150 Connection accepted Response: 226 Transfer OK Status: Received file listing
