IPv6 SSH-Tunneling

Hi,

I am currently trying to connect to an IPv6-only host via WinSCPs tunneling function.

This is the configuration I'm using:
<invalid link removed>
When connecting, instead of establishing the connection, it just shows this error message:
<invalid link removed>

I have tried the current nightly build, but apart from the nicer error icon :mrgreen: , nothing changes:
<invalid link removed>

The issue can be reproduced with OpenSSH and dropbear SSH servers.

Any ideas?

Thank you very much,
Tobias

Please attach a full log file showing the problem.

Hi,
I will post a log shortly.

In the meantime I have figured out, that putting the IPv6 address in [ ] brackets fixes the problem.

EDIT: Log is now attached.

Best regards,
Tobias

Thanks for your response. Though I do not see any IPv6 address in the log.

That might be part of the problem :mrgreen:

I have used IPv6 addresses to connect in this log.
Does WinSCP internally use PuTTY to provide this tunneling feature?
If so: I figured out, that PuTTY needs square brackets around an IPv6 address to make it work.

It might be enough to just encapsulate every IPv6 address in [ ] if it is sent to your tunneling method.

So long,
Tobias

I do not think so. WinSCP logs the IP address exactly as your enter it. Can you please try again? Posting a screenshot and a corresponding log file?
