How to get a list with all the hosts connected to a domain? (CentOS 6.5)

I want to print a list of all the hosts connected to the domain.

I'm looking for a command which does more or less what that one in Powershell does, but for Linux:

Get-ADComputer -Filter * | ForEach-Object {$_.Name}

So, what I want to do is getting a list with all the hosts on a domain and then compare it with all the hosts which are already monitored with Nagios.

The computer on which the command will be executed is the Nagios-server (not on the DC itself).

There's no convenient wrappers that intergrates with Active Directory as the cmdlets you have in powershell. However, Active Directory is an LDAP server, and you can pull out the info with the ldapsearch tool, this query fetches all the registred computers in out Active Directory domain:

ldapsearch -LLL  -H ldap://ad.ourdomain.local  -x  -D 'OURDOMAIN\user' -w 'thepassword' -b 'dc=ourdomain,dc=local' 'objectClass=computer' name

  • ad.ourdomain.local is the host name or IP address of an active directory domain controller.

  • OURDOMAIN\user is your domain name, and an existing user name (e.g. ACME\Jon). i.e. the username one uses when logging into a domain account on a windows machine

  • thepassword is the password of the above user Jon

  • dc=OURDOMAIN,dc=local is the top level LDAP DN, e.g. dc=acme,dc=local, it might be dc=acme,dc=com`, or something else. I don't know an easy way to figure it out except pulling the info out of ADExplorer
