babariviere / port_scanner-rs Goto Github PK

Hi,

I'm having new difficulties with port_scanner::scan_port after upgrading from v1.5 from v1.2 on OS X 10.11, and I can't go back to 1.2 because you've yanked it from crates.io (there's other ways to do this but I don't want to go there yet)

scan_port is always returning false.

I'm kinda at a loss beyond that.

Cheers,
Bob

I've been trying out scan_port_addr on two of my servers and one of them was scanned instantly, returning me the correct result of which ports were open. However with the same code, on another similar server, the process could continue Running ... indefinitely until I had to Ctrl - C it. What could be the reason for this to happen?

Thank you for releasing this as a Rust library! It's simple but very useful. However, I have a feature proposal. 🙂

When working with Docker, it's normal to have multiple containers on your system, each with it's own network address. These containers are often started asynchronously, and it takes them a while to make a port available. In the cage tool, I need to poll containers to see if they have an open port. Ideally, it would have a ToSocketAddrs argument like bind: bind<A: ToSocketAddrs>(addr: A).

Would you be interested in supporting this feature in your library? I could send you a PR.
