#5850 closed defect (worksforme)

illegal port command using FTPS transfer

Reported by: lee.norman@… Owned by: dkocher
Priority: normal Milestone: 4.1
Component: ftp-tls Version: 4.0.2
Severity: major Keywords:
Cc: Architecture: Intel
Platform: Mac OS X 10.6

Description

after upgrade to 4.0.2, every time I use FTP-SSL connection to transfer files from my transfer server, it errors out with illegal PORT command. I can use plain FTP to transfer file with no issue on this version.

I used 4.0.1 with no such error. There is no change in the ProFTPD version used on the server side, still 1.3.3a.

I set the Severity to high because I cannot transfer using FTP-SSL anymore.

Thanks in advance for looking into this problem. I have uploaded the log drawer transcript.

Hi - I have not change the bookmark since I upgraded to V4.0.2... wondering why it worked before. I have tried to set it to PASV mode and it worked OK. For plain FTP, ACTIVE mode worked just fine. Sounded like an issue... but I got an resolution. Not a problem anymore.

This change was made in r8557. We have no more an automatic fallback for general FTP errors when opening data sockets.
