[augeas-devel] Augeas Hosts_Access lens

[Raphaël Pinson]

Hi Eugene,


When you have questions about Augeas, it is easier to ask on the
mailing list (which I added as Cc) so that others can benefit from the
answers.

The easiest thing to know that is to try it in a file. Create a file
with multiple addresses and see how Augeas understands it (using
augtool for example, or augcheck from [0]).

The test file (in
/usr/share/augeas/lenses/tests/test_hosts_access.aug) also contains
some useful examples:


let multi_client = "sshd: 10.234. , 192.168.\n"

test Hosts_Access.lns get multi_client =
  { "1"
    { "process" = "sshd" }
    { "client" = "10.234." }
    { "client" = "192.168." }
  }


which shows that multiple IPs get mapped as multiple "client" nodes.

That is true.

Just implemented it in commit 91633265b2e0ceef91997f266a6e178654d389a9. See [1].
