Using IPv6 for SFTP (SSH)

Support
#1

Is it possible to use IPv6 address for a host in the SFTP (SSH) setup? I have tried every wasy I can think of from hostname to the IP address in brackets and it all fails.

#2

According to this old (and closed) Github issue it should (unless something got broken between there and here).

#3

So I saw that earlier and had tried the brackets already. Running the command in that thread is useless under linux as it is a windows binary.

#4

Should have mentioned that this is running on a CentOS 7 server.

#5

This issue was opened in 2012, so I suppose it is related to version 1.3. If that’s the case, the issue does not apply to Duplicati 2.

#6

Using brackets with the IP, I get:

Failed to connect: Could not resolve host ‘[2601’

Using no brackets I get:

Failed to connect: The socket is not connected

Using a fqdn in the linux host file, I get:

Failed to connect: Could not resolve host ‘train.internal.saroza-webb.com’

Using real DNS with a AAAA record, I get this:

Failed to connect: Could not resolve host ‘train.saroza-webb.com’

#7

Ah…Linux and old stuff - two (of many) things I’m still trying to get better at.

Thanks for the clarification and correction. :slight_smile:

#8

That is really a question for the underlying library “SSH.Net” (aka Renci SSH.Net):

I cannot find anything on IPv6 on the site, but maybe you can open an issue there?
