error sftp on altap 2.52 - connection refused

[jpermana]

I tried SFTP with altap salamander 2.52 and got error, while working fine with Altap salamander 2.51.

Any idea why ?? and how to resolve it ??

[Jan Rysavy]

Are you using any firewall on your computer? It looks like Salamander is blocked. Could you connect using FTP plugin to our (ALTAP) bookmark?

What about Plugins > Check Version > Check for new versions, does it work?

Hi Jan,

The firewall is Off. Also I was able to FTP to Altap bookmark (both 2.51 and 2.52)

The winscp plugin version is 1.62 for Altap 2.52 and version 1.51 for Altap 2.51.

Following link describes common causes of this error for WinSCP application. They mostly apply to WinSCP plugin for Altap Salamander, with the only difference being that the plugin does not support FTP protocol.

Also, if the link does not help, please post a log files both from 2.52 and 2.51. See logging pane on WinSCP login dialog.

Hi Martin,

Attached comparison Altap 2.52 and Altap 2.51. On Altap 2.51, I tried SFTP, SFTP (allow SCP fallback) and SCP, all works, mean I can connect. On Altap 2.52, none of these configuration work, all with the same result "network error : Connection refused"

How do I get the log file ?

Thanks

Please setup both WinSCP to create log files:

Hi Jan, Martin,

I found the problem.

Thanks

[Jan Rysavy]

What was the problem?

[jpermana]

can not use localhost, i have to put 127.0.0.1

I just looking at the log, then there's the problem.

I encountered the same problem in another program (on W7x64) just yesterday. The lookup for localhost returns an IPv6 address and an invalid/unusable IPv4 address. In my case, the IPv4 address was 0.0.0.0.

[Jan Rysavy]

Yes, reopening this problem. I can confirm there is problem with WinSCP on x64 Windows 7. localhost is resolved as "::1" instead of "127.0.0.1". It does work in FTP client so it looks to be WinSCP related.

Hi Jan,

So is this fix on altap 2.52 ?

[Jan Rysavy]

Martin Prikryl, author of WinSCP plugin, is still working on it.
