# The `.netrc` file
|
|
|
|
Specifies automatic login information for the `ftp` and `rexec` commands.
|
|
|
|
It is located under a user's home directory (`~/.netrc`) and must be owned
|
|
either by the user executing the command or by the root user.
|
|
If the .netrc file contains a login password, the file's permissions must be set
|
|
to `600` (read and write by its owner only).
|
|
|
|
## Format
|
|
|
|
The file can contain the following entries separated by spaces, tabs, or new
|
|
lines:
|
|
|
|
- `machine` _hostname_: this begins the definition of the automatic login
|
|
process for the specified _hostname_; all the following entries, up to a new
|
|
`machine` entry or the end of the file, will apply to _hostname_
|
|
- `default`: like `machine`, but matches any hostname; there can be only 1 in
|
|
the whole file and it is considered the last entry (entries following it will
|
|
be ignored)
|
|
- `login` _username_: the full domain user name used for authentication; if
|
|
found the automatic login process initiates a login with the specified
|
|
_username_, else it will fail
|
|
- `password` _password_: the password to use for authentication; it must be
|
|
set at the remote host and must be present in `.netrc`, otherwise the process
|
|
will fail and the user is prompted for a new value
|
|
> passwords in this fields cannot contain spaces
|
|
|
|
The two formats below are equivalent:
|
|
|
|
```text
|
|
machine example.com login daniel password qwerty
|
|
machine host1.austin.century.com login fred password bluebonnet
|
|
```
|
|
|
|
```text
|
|
machine example.com
|
|
login daniel
|
|
password qwerty
|
|
machine host1.austin.century.com
|
|
login fred
|
|
password bluebonnet
|
|
```
