SFTP with IPv6 address

Help & Support
1

Hi ,

I would like to SFTP to a device with an IPv6 address only.
I've tried to enter the address between square brackets [ffff:...] but that doesn't seem to work.

Can I use an IPv6 address for SFTP ?

Greetings,
chuvke

Hi,

I tried severals forms of the ipv6 address but none of them seem to be accepted (full 64bit or shortened form with :: )

Is IPv6 supported at all ? Couldn't find it in the documentation.

Grtz, chuvke

Only IPv4 at the moment, to my knowledge.

Hi Leo, Hi DOpus team!

I'd like to have IPv6 support as well VERY MUCH. Tried to use the wonderful sftp lister but it's working with IPv4 only.

Thank you!

BR,
Sven

Do you intend to support IPv6 for DOpus v12 ? So I could use the Holiday Sale for an update :wink:

All new Automotive Linux ECUs we are working with support IPv6 only, so I'm stuck here! This way I can't convince my boss to buy a new DOpus version.

In case someone needs IPv6 support for sftp, download https://sourceforge.net/projects/unix-utils/files/socat/1.7.3.2/, copy the files to some directory and then run

socat-1.7.3.2-1-x86_64\socat.exe TCP-LISTEN:22222,bind=127.0.0.1,fork TCP6:SOME_HOSTNAME_FROM_HOSTS_FILE:22
or
socat-1.7.3.2-1-x86_64\socat.exe TCP-LISTEN:22222,bind=127.0.0.1,fork TCP6:[SOME_IPv6_ADDRESS]:22

Of course this can be combined in a batch scipt like

set CMD_SOCAT=socat-1.7.3.2-1-x86_64\socat.exe
start /b %CMD_SOCAT% TCP-LISTEN:22222,bind=127.0.0.1,fork TCP6:[SOME_IPv6_ADDRESS_1]:22
start /b %CMD_SOCAT% TCP-LISTEN:22223,bind=127.0.0.1,fork TCP6:[SOME_IPv6_ADDRESS_2]:22
start /b %CMD_SOCAT% TCP-LISTEN:22224,bind=127.0.0.1,fork TCP6:[SOME_IPv6_ADDRESS_3]:22

to support multiple IPv6 targets in parallel. The task(s) / batchfile must not be closed/killed! Additionally Directory Opus FTP caching needs to be disabled. Set Preferences / Miscellaneous / Advanced: ftp_do_not_cache to "true", otherwise all entries in the lister are wrong if you use more than one connection in parallel.

After starting the task, setup a connection in DirOpus to "Secure SFTP via SSH (Port 22)", enter 127.0.0.1 as host address and set port to 22222. By changing the port, you can address optional other IPv6 addresses.

Works like a charm!
