Add utility function to retrieve local IP address #58

Closed sweep-ai[bot] closed 10 months ago

sweep-ai[bot] commented 10 months ago

Description

This PR adds a new utility function get_local_ip to the utils directory. The function retrieves the local IP address of the system and is compatible with macOS, Linux, Windows, and BSD.

Summary

Created a new file local_ip.rs under the utils directory.
Implemented the get_local_ip function that returns a Result<String, std::io::Error>.
Used the std::net module from the Rust standard library to retrieve the local IP address.
Handled potential errors that might occur when retrieving the local IP address.
Added unit tests to ensure the correctness of the function.

Please review and merge this PR. Thank you!

Fixes #57.

is there any other way to retrieve the local IP address without using ip binding?

Hi @SkuldNorniern,

I decided to make the following changes:

File Path Proposed Changes

src/utils/local_ip.rs Modify src/utils/local_ip.rs with contents:
• Replace the current implementation of the get_local_ip function with the following code:
```rust
use if_addrs::get_if_addrs;
use std::io;

pub fn get_local_ip() -> io::Result {
let interfaces = get_if_addrs()?;
for interface in interfaces {
if interface.is_loopback() || !interface.ip().is_ipv4() {
continue;
}
return Ok(interface.ip().to_string());
}
Err(io::Error::new(io::ErrorKind::Other, "Failed to retrieve local IP address"))
}
```

File Path	Proposed Changes
`src/utils/local_ip.rs`	Modify src/utils/local_ip.rs with contents: • Replace the current implementation of the `get_local_ip` function with the following code: ```rust use if_addrs::get_if_addrs; use std::io; pub fn get_local_ip() -> io::Result { let interfaces = get_if_addrs()?; for interface in interfaces { if interface.is_loopback() \|\| !interface.ip().is_ipv4() { continue; } return Ok(interface.ip().to_string()); } Err(io::Error::new(io::ErrorKind::Other, "Failed to retrieve local IP address")) } ```

and can you also make a code that parse the input text like 192.168.0.0/24 and compare with 192.168.0.15 if the ip is in/same with the 192.168.0.0/24

Hi @SkuldNorniern,

I decided to make the following changes:

File Path Proposed Changes

src/utils/ip_parser.rs Create src/utils/ip_parser.rs with contents:
• Create a new file ip_parser.rs under the utils directory.
• Implement a function parse_subnet that takes an input text in the format 192.168.0.0/24 and returns a tuple (String, u32) representing the IP address and subnet mask.
• Implement a function is_ip_in_subnet that takes an IP address as a string and a subnet tuple (String, u32) and returns a boolean indicating if the IP is in the same subnet.

src/utils/local_ip.rs Modify src/utils/local_ip.rs with contents:
• Import the parse_subnet and is_ip_in_subnet functions from ip_parser.rs.
• Modify the get_local_ip function to also accept an optional subnet parameter.
• If a subnet is provided, parse it using the parse_subnet function.
• Compare the retrieved local IP address with the subnet using the is_ip_in_subnet function.
• Return the local IP address only if it is in the same subnet, otherwise return an error.

File Path	Proposed Changes
`src/utils/ip_parser.rs`	Create src/utils/ip_parser.rs with contents: • Create a new file `ip_parser.rs` under the `utils` directory. • Implement a function `parse_subnet` that takes an input text in the format `192.168.0.0/24` and returns a tuple `(String, u32)` representing the IP address and subnet mask. • Implement a function `is_ip_in_subnet` that takes an IP address as a string and a subnet tuple `(String, u32)` and returns a boolean indicating if the IP is in the same subnet.
`src/utils/local_ip.rs`	Modify src/utils/local_ip.rs with contents: • Import the `parse_subnet` and `is_ip_in_subnet` functions from `ip_parser.rs`. • Modify the `get_local_ip` function to also accept an optional subnet parameter. • If a subnet is provided, parse it using the `parse_subnet` function. • Compare the retrieved local IP address with the subnet using the `is_ip_in_subnet` function. • Return the local IP address only if it is in the same subnet, otherwise return an error.

a code that parse the input text like 192.168.0.0/24 and compare with 192.168.0.15 if the ip is in/same with the 192.168.0.0/24 into a separate code please, revert the previous change

can you redo the get_local_ip function to use the pnet crate? here is the documentation link: https://docs.rs/pnet/latest/pnet/

and can you fill up the get_local_ip function?

fill up the get_local_ip function properly not as a unimplemented feature and also write a check_is_subnet function
