I just used the standard file manager with Bodhi as means to connect to an FTP server. In fact, I was using the standard Bodhi file manager to connect to an old mobile device via an FTP server created on the mobile device. Interestingly, the mobile device was a Blackberry 10 device. It's worth noting that Blackberry 10 (BB10) devices can install Android applications via apk applications form such "app stores" as f-Droid. Anyways, I installed an FTP server on the BB10 mobile device. From there, I connected to the ftp address via the standard Bodhi file manager with a location that was something similar to ftp://[IP adress] and, voila! I was able to access all of the files from the device! From here, I am able to directly access the various files and folders on the device, modify them, and transfer files to the Bodhi machine.
It might be worth sharing that I successfull setup a LAMP server (LAMP is an acronymn for "Linux Apache MySQL PHP) on the "old" IBM T40. I was working to build a little "cloud" setup. The entire process was going well. Last month I finished reading a book to update my knowledge of PHP7 and familiarizing myself with MySQL and Apache, and dug up an older book to begin an intensive project. The frustrating part was that I have an older book on PHP5 and some of the functions are obsolete (in particular, "mysql" which is now "msqli" in PHP) which meant I had a great amount of troubleshooting to work through.
Unfortunately, the project got interrupted. And this part of the story is not worth sharting. In any case, I intend to get back to this work in the near future.
My point is the following: If you have an old computer laying around, and by "old" I mean anying within the last 15 years, perhaps you can use Bodhi 32bit Legacy and setup your own FTP server?
Sure, it's "faster" to use non GUI Linux to setup a server environment in order to ensure the machine's resources are dedicated to operating the server and not redirected to GUI performance. Nevertheless, Bodhi 32 bit Legacy is incredibly light and from my minimal experience thus far, it works well as a means to create a server/cloud setup using an old machine.
I had inended to create a thread sharing my experience thus far using Bodhi as a means to transform an "old" machine into a personal server/cloud, however -- as I've said above -- the project got interrupted.
Nevertheless, if anyone's interested, I can share what I've learned thus far using Bodhi 32bit Legacy to transform an old machine into a server for a personal "cloud". However I'm not sure if anyone's interested and I suspect the Bodhi team quite familiar with LAMP servers and topics similar.
Hopefully you find something of value in this post wimc that assists you with your FTP issue.
