Description Sanchke Dellowar 2016-08-27 23:16:46 UTC
Linux Mint 18 (Cinnamon).

I have .odt & .otg on a local server who's address is
When attempting to open them (via Nemo), Libreoffice asks for credentials, I fill them in. Press 'OK', then I get a dialog box saying:

"The host name could not be resolved." - And that's that no file opened.

Going into more detail, I get the same error attempting to open files using FTP via:
 - Bash (`libreoffice5.2 ftp://username@`)
 - Libreoffice's Open Remote File Dialog
 - Libreoffice's Open File Dialog
 - Nemo (File Browser)
So out of all the ways to get to the file, all of them fail the same way.

Now here's the kicker: if I use SFTP or SSH, it works perfectly fine. So this is obviously a FTP-only issue.

Also allow me to add that this same FTP connection works fine with all other services requiring it: so it is certainly not an issue with the server or client computers, it is only libreoffice having issues with it.

Thank you very much!

PS: Before anyone get's on their high horse about why not to use FTP: I am using FTP because I need all the speed I can get, for I am dealing with large files. ;)

The author of bug 72460 managed to get his working via the 'open file' -> '...' dialog. I am not able to do that.

Since the bug hasn't been confirmed independently, let's leave status as UNCONFIRMED.

I tried accessing files via FTP (anonymous user) over home network, and had no problem. Used LibreOffice on Ubuntu 14.04.

Interesting. Any chance you could test without using anonymous user? And are you entering IP or domain as a host?

Sure, I just tried with a normal user, with same results. I've been using IP address, and tried three of the four methods you listed (except the last one).

So either the message is completely bogus (for example it can't connect to the FTP server for some reason, but gives an unrelated error message), or the issue is indeed that it's trying to resolve an IPv4 address as host name... like, maybe LibreOffice somehow gets the idea the system is only using IPv6 addresses, so it tries to resolve an IPv4 one as host name?
I don't know if that can actually happen, it's just an example of what my thought process would be (there's also the complication that then it likely wouldn't work fine with other services).

Could you please try to reproduce it with the latest version of LibreOffice from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the latest version.
