Symlink not recognised using Proftpd Server

[nicofr]

Hello Guys,

Recently i have upgrade my proftpd server to last release (1.3.4a) on AIX servers (6.1) and filezilla client even at the last release (3.5.3) on Windows does not reconize anymore the symlinks. It happens only with filezilla clients. All other clients i have (standard ftp windows, standard ftp client on AIX) works perfectly but i'd rather filzilla for my customer because it's a very good client !
But now the symlinks are displayed as files and not as directories and we can not go into the symlinks.
Mays be this issue is a combination of proftpd last release and filezilla but now i'am block.
Any ideas would be very appreciated.
Thanks for your support.
Nicolas

Hi,

Same bug for me. Symlinks are shown as file and when trying to download, I have a 550 error "not a regular file".
I tried with proftpd version 1.3.3g and it works (linux SLES11 SP1 server). The small arrow link symbol doesn't appear on the directory icon but the link is recognized.
With other ftp client, links are OK with proftp 1.3.4a.

With my old proftp server 1.3.1, links were well displayed with a "link dir" icon.

All test made with FileZilla 3.5.3

Can you please provide logs with raw directory listing enabled? - ​http://trac.filezilla-project.org/wiki/TicketSubmissionGuide#Logs

It simply might be a bug that the FTP server does not report the items as symbolic links using MLSD.

Maybe see #4490 for what I mean.

Debug log with raw directory listings.

I am also facing this exact problem.

Using Filezilla 3.5.3 and ProFTPD 1.3.4a Server.

Using other FTP clients they see the symlink as a folder fine. Howfile filezilla see's the folder public_html as a file, if I double click it doesnt transfer, if I manually navigate to it I get into the folder.

I reopened #4490 - the issue is that RFC 3659 has an Errata (ID 500), and instead of 'slink', the MLST token was changed to 'symlink' plus a small change to conform with existing BNF syntax constraints. The correct syntax to support for a symbolic link should be:

Type=OS.unix=symlink;Perm=;Unique=keVO1+4G4; foobar

You can find discussions about this, for example here:

• ​http://www.proftpd.org/docs/modules/mod_facts.html
• ​http://www.rfc-editor.org/errata_search.php?rfc=3659

For the record, we see the issue using the Mac client (while this ticket was opened as a Windows client issue).
