Question 1

How to set up an SFTP server using pkg/sftp in Go?

Accepted Answer

Integrate the server with Go's crypto/ssh package for authentication; examples on pkg.go.dev show basic setup, but you'll need to handle file system permissions and connection management manually.

Question 2

pkg/sftp vs scp for file transfers in Go – which is better?

Accepted Answer

pkg/sftp is better for programmatic operations within Go apps, offering features like directory listings and file stats, while scp is a CLI tool with simpler use but less control.

Question 3

Does pkg/sftp support resumable file transfers?

Accepted Answer

No, it doesn't have built-in support for resumable transfers; you'd need to implement custom logic for handling partial uploads or downloads based on file offsets.

Question 4

How to handle authentication with pkg/sftp client?

Accepted Answer

Use Go's crypto/ssh package for SSH key or password authentication; the sftp package relies on established SSH connections, so setup involves standard SSH configuration.

Question 5

Is pkg/sftp production-ready for large-scale deployments?

Accepted Answer

Yes, it's used in production, but performance depends on SSH connection overhead and Go's concurrency model; test with your workload for scaling issues.

Question 6

Can I use pkg/sftp with non-standard SFTP servers?

Accepted Answer

It aims to follow the SFTP protocol spec, but compatibility may vary with servers using extensions; check with your target server or add custom handling if needed.
