Blink: scp/sftp doesn't work on non-standard SSH port

[ghost]

I have configured a host named m and it uses a non-standard SSH port, and I can ssh m/mosh m without issue. However, it seems that scp/sftp still try to connect using port 22. curl makes no progress for over a minute before giving up. According to the remote host's sshd logs, no login attempt was performed.

blink> echo hello > hello.txt
blink> scp hello.txt m:~/hello.txt

Using sftp instead of scp doesn't seem to change anything. I have also tried using -p or -P to change the port.

Running Blink version 11.26 from App Store.

Yep, this is known issue and will be fixed in next release.

Thank you.

Not fixed in version 12.1 from App Store.

So, there is no yet way to scp with non standard port?

@idchlife and @0x0000null

Actually scp will pickup port from 'config' -> 'host' setting.
But first you have to 'ssh2' first to that host. It will add host to known hosts with rsa. (ssh currently adds esdsa, and scp doesn't recognize it)

we need to reimplement scp on top of libssh or OpenSSH

[idchlife]

wow, thanks for the information! It will help a lot!

Actually, found a bug with fresh compile. Fixed build 56

Fixed in version 12.2. (scp may still have issues: #624)

Hi @yury it seems that scp on Build 57 still not working.

Hi @thariman!

can you try with full destination path?

scp -v DockerIntro.pdf AI2:~/DockerIntro.pdf

[thariman]

OK It worked, both ways. Thank you.
