Documentation about the ncm-sendmail component

Ncm-sendmail-1.6 component

2 Functions:

1)The first check if the service is running,

2) The second function restarts the service.

(Both can be implemented with the notify/require parameters in puppet manifests)

Declaring the parameters (e.g my $cfgfilecf='/etc/mail/sendmail.cf';)

Configure state:

$tree
|-- manifests

| |-- init.pp
| |-- install.pp
| |-- local-users.pp
| |-- newaliases.pp
| |-- params.pp
| `-- service.pp
`-- templates
|-- local-users.erb
`-- sendmail.mc.erb

[Parameters]

$smart_host_enable=true,
$smart_host='cern.ch',
$accept_external_mail='true',
$masquerade_enable='true',
$user_domain='mail.cern.ch',
$local_relay_enable=true,
$local_users_file='/etc/mail/local-users',
$afs_forward_support=true

$sendmailmc_file = '/etc/mail/sendmail.mc'
$sendmailcf_file = '/etc/mail/sendmail.cf'
$file_group = 'root'

  • Modifying the sendmail configuration file
  1. masquerade_enable = true -->(put-line) MASQUERADE_AS(`<%= @user_domain %>')
  2. masquerade_enable = true -->(put-line) FEATURE(masquerade_envelope)dnl

  3. accept_external_mail = true -->(put-line) DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnl

  4. local_relay_enable = true -->(put-line) define(`LOCAL_RELAY',`<%= @user_domain %>')dnl ,LOCAL_USER_FILE(`<%= @local_users_file %>')dnl
  5. afs_forward_support = true -->(put-line) define(`confFORWARD_PATH',`$z/public/.forward.$w:$z/public/.forward:$z/.forward.$w:$z/.forward')dnl
Install the packages: 'sendmail', 'sendmail-cf', 'm4'

Configure the module ( the manifest is ready e.g: Generate sendmail configuration file)

And

  • Trying to guess all the non-afs users in the machine(default = root)
  • try to open the /etc/login.defs if failed hardcode the min/max local uid between 500 - 60000 ( <- this needs to be reviewed , Jarek)
  • Puppet approach of newaliases(does the same thing with sendmail component but better) if /etc/aliases.db is more recent, 0 if /etc/aliases is more recent 1 or aliases.db is absent and then it runs the newaliases command
Things to be done

  • How hiera plays with masterless approach
  • how i can extract the landb lib in order to have the landb_owner(s)
