wokaround for bad ftp server welcome message

2010-02-23 18:16

i want to connect to odd ftp server, that has wrong welceme message format.

instead, of standards complying

220 (vsFTPd 1.1.3 bla bla)

it returns

Running the FTPD
                Got past fork
                             changed group
                                          opened tty
                                                    /home/directory/bla/bla/log
/system/ftpd.logdoing signal
                            signal
                                  listening
                                           220 strange FTP server (Version 5.437
 Fri Dec 24 08:39:24 CST 2004) ready.

which of course is completely non-standard and doesnt comply to ftp prodotocl.
however, i have actualy found one ftp client that manages to get 220 out of this mess, and after that everything works fine. This client is CuteFTP Pro. Problem is, that none of other ftp clients (windows default, windows commander, ultraedit built in, filezilla) i have tried, understands that, and i would really like to use open source client instead of expensive and bloated cuteftp.

So, question is - could it be possible to do some kind of workaround in winscp, using some script/configuration or whatever, to get through this odd welcome message?

Is there something i can do, apart of downloading source and building my own custom version of winscp client?

Please post a full log file showing the problem.

To generate log file, enable logging, log in to your server and do the operation and only the operation that causes the error. For posting extensive logs you may use pastebin or similar application. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you may email it to me. You will find my address (if you log in) in my forum profile. Please include link back to this topic in your email. Also note in this topic that you have emailed the log.

and as i posted in previous post - problem is on the server side, it sends bad welcome message. what i want to achieve is some workaround so winscp would ignore that.

OK thanks. I see. Well let's see if more people use such a server.

I have no control over what welcome message the server sends as i am not admin, winscp is able to verify the ssl connection but is unable to comply with the welcome message.
