Hosts menu contains commands for creating and modifying hosts. In addition, this menu provides the search commands for searching hosts within a zone.
Most of the host specific commands are not in the Hosts menu itself, but are displayed as buttons when user views a host record. Some of these buttons such as Edit or Delete are only available when user has privileges to make modifications to hosts in that zone.
Search command is the default command when entering into Hosts menu. This command provides powerful search engine for hosts within current zone. See Table 5-5 for descriptions of the fields used in the command dialog.
Table 5-5. Search Hosts Dialog
| Field | Description | Example |
|---|---|---|
| Record type | Limits search to specific record type; <Any Type>, Host, Host reservation, Delegation, Plain MX, Alias, AREC Alias, Glue record, DHCP only | Host |
| Subnet | Search only hosts within specified network | |
| CIDR (block) or IP | Lmit search to given CIDR block or IP address (NOTE! this field supersedes the subnet field) | 192.168.1.128/25 |
| Domain pattern (regexp) | Limit search scope to hosts that have domainname that matches regular expression given in this field. | \.sales$ |
| Sort order | Sort search result by IP or hostname | by IP |
| Entries per page | Number of hosts to display per page | 256 |
| Search field | Defines the field that is searched for pattern defined in next field (Pattern). | Ether |
| Pattern (regexp) | Search hosts records for this regular expression in the field defined in "Search field" field. |
Last Search command performs the previous search again. This provides a quick way to redo a search you did earlier.
Add host command is used to create a host. This command displays slightly different dialog for administrators or users with "RWX" access to the zone than normal users who will get more restrictive dialog. See Table 5-6 for descriptions of the fields used in the command dialog.
Table 5-6. Add Host Dialog
| Field | Description | Example |
|---|---|---|
| Hostname | Hostname (without the zonename part of the host's FQDN) | ws001 |

| IP | Host's IP number (only if "Manual IP" selected in subnet field). | |
| Router (priority) | This field should be zero for hosts. For router interfaces, this should be set to positive priority value (1=highest priority). Priority is used for choosing "best" router interface when generating DHCP config for each subnet. | 0 |
| Group | Group which this host belongs to. | None |
| MX template | MX template to use for this host. | None |

| Ethernet address | Host NIC hardware (MAC) address (this must be unique within zone) | 00:00:01:23:45:66 |
| Asset ID | This field is reserved for organizational asset ID tag (this must be unique within server) | |
| Model | Host model information (informational) | |
| Serial no. | Host serial number (informational) | |
| Misc. | miscellaneous information about the host (informational) | |
| Expiration date | Host will automatically disappear from DNS & DHCP configurations after it has expired (sauron can automatically clean expired hosts from database when run with --clean option) |
Edit button is used to modify existing host. This button can only be used by normal user if she has necessary privileges to make modifications to the host. See Table 5-7 for description of the fields used in this dialog.

Delete button is used to delete a host. This button can only be used by normal user if she has necessary privileges to make modifications to the host. If a host has dynamic aliases that point to it those aliases are also automatically removed when the host is deleted.
Copy button can be used to "copy" a host easily. This button will take the information from the current host and use this information to pre-fill Add host command dialog. If hostname contains number it is incremented, otherwise number two (2) is appended to the end of the hostname.
Move button is used to move a host into a new subnet. After selecting new subnet for this host, next available IP address within the auto assign address range of that network is suggested as new IP address for the host. This button can only be used by normal user if she has necessary privileges to make modifications to the host.
Alias button is used to add a dynamic (CNAME or A record) alias for a host. This button can only be used by normal user if she has necessary privileges to make modifications to the host.
Add alias command is used to add a static (CNAME) alias. This command is meant for adding static "out-of-zone" aliases only. Normally aliases should be added using Alias button, which will create a dynamic alias for that host. This command is available for administrator and users with "RWX" access to the zone.
Add MX entry command is used to add plain MX record (without A records or anything). This command is available for administrator and users with "RWX" access to the zone.
Add delegation command is used to add a zone delegation (NS records). This command is available for administrator and users with "RWX" access to the zone.
Add glue rec. command is used to add glue records that are sometimes required for delegations where one ore more delegated zone's name servers are within that zone. This command is available for administrator and users with "RWX" access to the zone.
Add DHCP entry command is used to add a "host" entry that will only appear in DHCP configuration, but not in DNS configuration. This command is available for administrator and users with "RWX" access to the zone.
Add SRV rec. command is used to add a SRV records. This command is available for administrator and users with "RWX" access to the zone.
Add reservation command is used to add a host reservation. Host reservations can be used to reserve hostnames and IP numbers for future use.
Network Settings button displays network settings for selected host. This will include IP address, netmask, network address, broadcast address, and default gateway for the host.
History button displays history of this host record. This will include information like when the record was created, and when it was modified and by whom. This option is available for users who by default have authorization level of 1 or higher (this can be controlled via variable ALEVEL_HISTORY in configuration file).
Ping button allows user to run "ping" command against the selected host. This option is only available when it is explicitly enabled in configuration file and user has at least the required authorization level.
Traceroute button allows user to run "traceroute" command against the selected host. This option is only available when it is explicitly enabled in configuration file and user has at least the required authorization level.
