(1.9.8) SFTP not working?

[Alexander Schuch]

Our server was switched from normal ftp to sftp. But I
cannot login with FileZilla 1.9.8 using 'FTP with explicit
encryption'. All I get is following:

Status: Connecting to xxx.xxx.xxx.xxx:22 ...
Status: Connected with xxx.xxx.xxx.xxx:22. Waiting for
welcome message...
Response: SSH-1.99-OpenSSH_3.1p1

(nothing happens for about 5 minutes...)

Error: Timeout detected!

But when I use another client from
<​http://www.ssh.com/products/ssh/download.cfm>, it
works... A bug in FileZilla or maybe a server mis-
configuration or something totally different?

BTW: 'FTP with implicit encryption' doesn't work at all
and normal FTP says the same as with explicit
encryption.

You were trying to connect to an SSH server using SSL. It's a
little bit confusing but SFTP is FTP over SSH, whereas FTPS
is FTP over SSL.

FileZilla 1.9.8 does not support SFTP. But the next version,
1.9.9, will. I've already published beta versions of 1.9.9 with
SFTP support, you can download the latest one here:
​http://filezilla.sourceforge.net/beta.htm

Using my nice Win98SE maschine I always get:

Error: Can't initialize CSFtpIpC. Please make sure that
enough system resources are available!
Error: Unable to connect!

I even rebooted my computer but with no luck, i.e. same
message.

Thanks for reporting, it's fixed in beta 7

trace log of refused connection

[Alexander Schuch]

Using FileZilla 1.9.9.7 I still cannot connect to that SFTP
server. I've included a trace log. There is a typo in error
message "Error: FzSFtp.exe did not respone, terminating
connection." I think it should be 'respond'.

[Tim Kosse]

Could you please enable "Trace messages from the ftp
engine" in the debug settings and post the message log after
a failed connection attempt?
Can you connect to the Sourceforge SFTP servers?
​sftp://user:pass@filezilla.sf.net:22 (replace user and pass)

[Alexander Schuch]

I already traced the messages; they are located in a file to
download - check bottom of this page (or check here
<​https://sourceforge.net/tracker/download.php?
group_id=21558&atid=372241&file_id=26082&aid=573242>).

Trying to connect to SourceForge SFTP server results in
exactly the same messages... Just to tell you: I'm using
Win98SE.

[Tim Kosse]

Please try beta 8, I've tested it under Win98SE and it works.

original unchanged trace using 1.9.9.8

[Alexander Schuch]

Even the latest version 1.9.9.8 won't connect to SourceForge
SFTP server. I've included full unchanged trace log.

[Tim Kosse]

Please try beta 9. Someone else had the same problem and
beta 9 fixed it.

[Alexander Schuch]

Good work - well done! It works!
But there is still a minor issue concerning the 'reconnect'
feature. If I enter a wrong password and get rejected
using 'reconnect' won't ask for the password again.
