|
|
- Set capability `cap_net_raw` (to use RAW and PACKET sockets) for a given file:
|
|
|
|
`setcap '{{cap_net_raw}}' {{path/to/file}}`
|
|
|
|
- Set multiple capabilities on a file (ep behind the capability means "effective permitted"):
|
|
|
|
`setcap '{{cap_dac_read_search,cap_sys_tty_config+ep}}' {{path/to/file}}`
|
|
|
|
- Remove all capabilities from a file:
|
|
|
|
`setcap -r {{path/to/file}}`
|
|
|
|
- Verify that the specified capabilities are currently associated with the specified file:
|
|
|
|
`setcap -v '{{cap_net_raw}}' {{path/to/file}}`
|
|
|
|
- The optional `-n {{rootuid}}` argument can be used to set the file capability for use only in a user namespace with this root user ID owner:
|
|
|
|
`setcap -n {{rootuid}} '{{cap_net_admin}}' {{path/to/file}}`
