Node Full Search

For an explanation of each field, please see the Node help.

Search Fields

Name - String

Search for name. Note there are 5 types of name (see Name Type). If a domain is not specified, the name is searched for in all domains.

Example:
Search for all nodes starting with humsci:
Search for Name "humsci*"

Name Types - Checkbox

Select the types of names you wish to search for.

  • Node Name (most common type of name)
    In DNS jargon, a Node Name is an A type resource record. If a DNS server is queried for the address of this name, any of the active IP addresses may be returned.
  • Alias
    An alias, in DNS jargon, is a canonical name (CNAME type resource record). A canonical name cannot also be used as a mx record.
  • Interface Name (only found on Advanced Nodes)
    Name associated only with the active IP addresses of that interface.
  • IP Address Name (only found on Advanced Nodes Name associated with one specific IP address)
    DNS A type resource record.
  • IPC Address Name (only found on IPC Nodes Name associated with an IPC address)
    IPC Nodes do not use the IPC addresses themselves but are responsible for passing the addresses out (e.g., DSL routers). This is a DNS A type resource record.
Receives Mail For (MX) - String

In DNS jargon, Receives Mail For is an MX type resource record.

Example:
Find the machine that receives mail for mymail (i.e. me@mymail).
Search for 'Receives Mail For = mymail'

Only Node Types and Exclude Node Types - Checkbox

Select the Node Types you wish to search for or exclude. Note that Router, IPC and Advanced Nodes are separate access types. In other words, to add/modify/delete Node that is a Router, the User must have rights to Node and Router. Use "Exclude Node Types" allows to eliminate certain types.

  • Routers - because it is a separate access type, Router is generally used by Networking Systems for real routers.
  • IPCs - a Node that also passes out IP addresses to other machines
  • Advanced - a Node with extra features like Interface name, IP address name
  • Template - a Node that has an address space instead of IP address.

Example #1:
Find all Routers that are not Advanced
Search for Name = * and Only Node Type = Router and Exclude Node Type = Advanced
If the Name parameter is not included, the search will complain that no parameters were entered.

Example #2:
Find all Nodes starting with "ab" that do not have additional types
Search for Name = ab* and Exclude Node Type = Router, IPC, Advanced, and Template

IP Address - IP Address

Search for interface or IPC IP address.

Example:
Find Nodes in the top half of 171.64.20.0/24
Search for IP address = "171.64.20/24"

Pointer Preference - Radio Button

Search for IP addresses whose name preference is: all, closest, either

IP Address Status - Radio Button

Search for IP addresses that are active, inactive or either.

Hardware Address - Hardware Address

Also known as MAC address or Ethernet address.

DHCP - Radio Button

Search for Nodes with DHCP on, off or either

DHCP Options - Label

See the DHCP Help page for a list of supported DHCP options or click on "Options List" link.

Example:
Search for Nodes which get a configuration file from a server named "configserver.stanford.edu"
Search for "DHCP Options = next-server=configserver.stanford.edu"

Roaming - Radio Button

Search for Nodes with Roaming DHCP on, off or neither

Group - String

To add/modify/delete a Node, the User must belong to the same Group as the Node. To see list of all Groups, click on "Group list" link.

Example:
Find all Nodes in the Group "Sociology"
Search for Group = "Sociology"

Department - String

Search for the Department associated with a Node. See a list of all departments by clicking on "Department List" link.

Example #1:
Find all Nodes in "Bechtel International Center"
Search for Department = "Bechtel International Center"

Example #2:
Find all Nodes in Drama or Comparative Literature
Search for Department = "Drama or "Comparative Literature""

Location - String

Search by Node building. See a list of all locations by clicking on "Location List" link. Note that location name does not contain site and code anymore. Thus searching for location "Off Campus (00-002)" will fail. The right way to search would be "Off Campus".

Example:
Find all Nodes in Storey House or Columbae
Search for Location "Storey* or Columbae*"

Site - String

Site is also known as Quad.

Code - String

Code is also known as Building.

Expiration Date - Date

Note that NetDB takes NO actions based on this date. The date is merely for user convenience (for instance, tagging machines visiting for a conference).

Example:
Search for Nodes with Expiration Date on January 1, 2000.
On or After= 1/1/2000
Before= 1/2/2000

Make and Model - String

Make and Model have separate fields. See entire Make/Model list by clicking on "Make&Model list".

Example #1:
Find all Nodes which are Apple Performas
Search for 'Make = "Apple"' and 'Model = "Performa *"'

Example #2:
Find all Nodes made by Dell except Dell Optiplex
Search for 'Make = "Dell"' and 'Model = "not optiplex"'

OS - String

See the entire Operating System list by clicking on "OS list".

Example:
Search for Nodes running Redhat Linux or Caldera Linux
Search for "OS = linux and (caldera or redhat)"
or "OS = 'linux- redhat' AND 'linux- Caldera'"

Administrator - String

Node Administrators can be an individual person or an Admin Team. To search for a person, use either SUNet ID or full name. For best results, use the unique SUNet ID. To search for Admin Team, use the Admin Team field. Only one of the three fields can be used.

Example:
Find Nodes administered by the Admin Teams DCG and DSG
Search for Admin Team = "D?G"

Node User - String

Search by either SUNet ID or full name. For best results, use the unique SUNet ID. Note that only one field can be used at a time.

Custom Fields - Label

Custom Fields are user customizable fields. The equal sign (=) separates the label from the value.

Example #1:
User has customized one field to be AssetNum.
This will be a search for Node with asset number 1234567
Search for "Custom Field = 'AssetNum=1234567'"

Example #2:
User has customized one field to be TSO port.
This will be a search for Node connected to TSO 345
Search for 'Custom Field = "TSO port=*345*"'

Comment - String

Example:
Search for Node with comment mentioning "special" and "blue"
Search for comment = "*special*blue*".

Created By - String

Created By is the User who created a record. Search by either SUNet ID or full name. For best results, use the unique SUNet ID. Note that only one field can be used at a time.

Example:
Find records created by either John Doe(jodoe) or Jane Doe(jadoe)
Search for "Created By SUNet ID = jodoe or jadoe"
or "Created By Name = Jane Doe or John Doe"

Created Date - Date

Created Date is the date that a record was created.

Example:
Search for records created on January 1, 2000.
On or After = 1/1/2000
Before = 1/2/2000

Modified By - String

Modified By is the last User to change this record. Search by either SUNet ID or full name. For best results, use the unique SUNet ID. Note that only one field can be used at a time.

Example:
Find records modified by either John Doe(jodoe) or Jane Doe(jadoe)
Search for "Modified By SUNet ID = jodoe or jadoe"
or "Modified By Name = Jane Doe or John Doe"

Modified Date - Date

Modified Date is the last time the record was modified.

Example:
Search for records modified on January 1, 2000.
On or After = 1/1/2000
Before = 1/2/2000

General Examples

1. Find Users that have been adding Nodes to 175.1.7 who are not Joe LNA.

Search with the following parameters:
  • Created By - set display to "Yes"
  • Created By Name = not "Joe LNA"
