curl/docs/cmdline-opts/interface.d

Long: interface
Arg: <name>
Help: Use network INTERFACE (or address)
See-also: dns-interface
Category: connection
Example: --interface eth0 $URL
Added: 7.3
---
Perform an operation using a specified interface. You can enter interface
name, IP address or host name. An example could look like:

 curl --interface eth0:1 https://www.example.com/

If this option is used several times, the last one will be used.

On Linux it can be used to specify a VRF, but the binary needs to either
have CAP_NET_RAW or to be run as root. More information about Linux VRF:

docs: add categories to all cmdline opts Adapted gen.pl with 'listcats' This commit is a part of "--help me if you can" Closes #5680 2020-07-13 20:15:04 +08:00			`Category: connection`
curl.1: provide examples for each option The file format for each option now features a "Example:" header that can provide one or more examples that get rendered appropriately in the output. All options MUST have at least one example or gen.pl complains at build-time. This fix also does a few other minor format and consistency cleanups. Closes #7654 2021-08-31 22:37:14 +08:00			`Example: --interface eth0 $URL`
cmdline-opts: made the 'Added:' field mandatory Since "too old" versions are no longer included in the generated man page, this field is now mandatory so that it won't be forgotten and then not included in the documentation. Closes #7786 2021-09-28 17:50:07 +08:00			`Added: 7.3`

--interface: add support for Linux VRF The --interface command (CURLOPT_INTERFACE option) already uses SO_BINDTODEVICE on Linux, but it tries to parse it as an interface or IP address first, which fails in case the user passes a VRF. Try to use the socket option immediately and parse it as a fallback instead. Update the documentation to mention this feature, and that it requires the binary to be ran by root or with CAP_NET_RAW capabilities for this to work. Closes #2024 2017-10-27 02:42:55 +08:00
