Posted by John Carl Villanueva on Wed, Jul 17, 2019 @ 10:55 PM

[Last updated July 17, 2019] Last time, we tackled the problem system administrators encounter when their passive FTP or FTPS connections have to pass through a NAT firewall or router. A similar problem can happen when you're dealing with the same type of connections and a reverse proxy. It gets even more complicated when you have to deal with both external and internal users. Let me show you how to deal with that.

Drawbacks of the 4 Most Popular File Transfer Methods | JSCAPE

Posted by John Carl Villanueva on Thu, Aug 16, 2018 @ 11:28 PM

This post was originally published on June 2013 but was last updated on August 16, 2018.


Sending someone multi-megabyte or even gigabyte-sized files is getting more common these days. For example, in our Help Desk, it's normal to receive a zip file of log data of over 100MB. While it might seem this is just a highly specialized case that's only common in the tech business, it's not.

A single high resolution image can already run up to a few megabytes, while a regular video can easily exceed 50MB. We often use videos and images in our Power Point presentations and other files, so media file attachments of these types can be pretty common. 

The problem is, people often resort to solutions that aren't suitable for sending large files, especially in an enterprise environment. Email, which is the most common way of sending files, is not a suitable big file transfer method for this. So are other methods many people unwisely use at work for sharing really big files; files that are even much larger than a gigabyte.
