116 Using the DNS Failover (DFO) Utility
Options
(continued)
•
/failback
—Denotes a failback procedure, performed after a failed source is recovered or
restored (required for modify on failback)
•
fbswitch
(optional)—By default, the DFO utility will only failback records in the
dfo_failback_config.dat
file.
fbswitch
allows you to enter a search criteria to identify
the records to change back, even if they are not in the configuration file.
fbswitch
is also used
if the
dfo_failback_config.dat
file is missing
•
/lock
—Allows Active Directory locking for the A type record of the source specified without
modifying the record
•
/unlock
—Allows Active Directory unlocking for the A type record of the source specified
without modifying the record
•
trusteename
—The domain account for the source server machine (
domain\machine$
). DFO
attempts to deny write permissions to the DNS A record on failover for the account identified as
the trustee. “Deny write permissions” is then removed from the DNS A record on failback. This
keeps the source server from reclaiming its DNS A record if it comes back online prior to
failback. You can enter multiple /trustee switches (for example, /trustee administrator /trustee
user).
•
/verbose
—Logging and display level set to maximum detail (optional)
•
/FLUSHDNS /machine [machine_FQDN])—
Run the
ipconfig /flushdns
command to
flush the DNS cache on the specified machine (remote or local (.))
•
/TTL
—Update the TTL value of all modified records
•
seconds
—The number update interval for the TTL (in seconds)
•
/addomain
(optional)—The name of the Active Directory domain where the source
A Type record’s object is stored. This is used if the Active Directory Domain location of the DNS
record object is different than the DNS domain name location for that object. The DFO utility
will attempt to locate the Active Directory record object for locking (see the “
trusteename
” for
more information), but if the DFO utility is unable to determine the location of the Active
Directory object, it will use the ADFQDN location if specified.
•
/test
—Test mode. Modifications are not
actually
made, just listed (optional)
•
/debug
—Forces DFO to write the DNS resource record as-is to the
dfolog.log
file prior to
any DFO modify or list activity
•
/?
—Displays the syntax of the DNS Failover utility
•
/help
—Displays the syntax of the DNS Failover utility
Password
Encryption
•
/setpassword
—
NOTE:
This function must be run separate from a modify or list activity.
/setpassword
is designed to allow the user to store a username/password pairing in an
encrypted file for later use. (optional, but required if
/getpassword
will be used)
•
/getpassword
—Once a username/password pair has been encrypted and stored using
/setpassword
, this command can be used at the command line to retrieve the password
associated with a specific username. It is designed to avoid storing passwords in clear text.
