## Host Aliases
|
|

b1b450 |
## Groups of machines. You may prefer to use hostnames (perhaps using

|
|
b1b450 |
## wildcards for entire domains) or IP addresses instead.
|
|
|

## User Aliases
|
|
|
b1b450 |
## These aren't often necessary, as you can use regular groups
|
|
|
b1b450 |
## (ie, from files, LDAP, NIS, etc) in this file - just use %groupname
