The lifetime cannot exceed one week. A negative trust anchor selectively disables DNSSEC validation for zones that are known to be failing because of misconfiguration rather than an attack. When data to be validated is at or below an active NTA and above any other configured trust anchors , named will abort the DNSSEC validation process and treat the data as insecure rather than bogus.
This continues until the NTA's lifetime is elapsed. NTAs persist across restarts of the named server. The NTAs for a view are saved in a file called name. An existing NTA can be removed by using the -remove option. An NTA's lifetime can be specified with the -lifetime option. TTL-style suffixes can be used to specify the lifetime in seconds, minutes, or hours. If the specified NTA already exists, its lifetime will be updated to the new value. Setting lifetime to zero is equivalent to -remove.
If the -dump is used, any other arguments are ignored, and a list of existing NTAs is printed note that this may include NTAs that are expired but have not yet been cleaned up. Normally, named will periodically test to see whether data below an NTA can now be validated see the nta-recheck option in the Administrator Reference Manual for details.
If data can be validated, then the NTA is regarded as no longer necessary, and will be allowed to expire early. The -force overrides this behavior and forces an NTA to persist for its entire lifetime, regardless of whether data could be validated if the NTA were not present.
The view class can be specified with -class. All of these options can be shortened, i. Enable or disable query logging. For backward compatibility, this command can also be used without an argument to toggle query logging on and off. Query logging can also be enabled by explicitly directing the queries category to a channel in the logging section of named. Reload the configuration file and load new zones, but do not reload existing zone files even if they have changed.
This is faster than a full reload when there is a large number of zones because it avoids the need to examine the modification times of the zones files.
Dump the list of queries named is currently recursing on, and the list of domains to which iterative queries are currently being sent. The second list includes the number of fetches currently active for the given domain, and how many have been passed or dropped because of the fetches-per-zone option.
If the zone is configured to use inline-signing , the signed version of the zone is discarded; after the retransfer of the unsigned version is complete, the signed version will be regenerated with all new signatures.
Scan the list of available network interfaces for changes, without performing a full reconfig or waiting for the interface-interval timer. Dump the server's security roots and negative trust anchors for the specified views. If the first argument is "-", then the output is returned via the rndc response channel and printed to the standard output. Otherwise, it is written to the secroots dump file, which defaults to named.
This command requires that the auto-dnssec zone option be set to allow or maintain , and also requires the zone to be configured to allow dynamic DNS. In either case, only completed keys are removed; any record indicating that a key has not yet finished signing the zone will be retained. This is the only supported mechanism for using NSEC3 with inline-signing zones.
Currently, the only defined value for hash algorithm is 1 , representing SHA The flags may be set to 0 or 1 , depending on whether you wish to set the opt-out bit in the NSEC3 chain. To set the opt-out flag, 15 iterations, and no salt, use: rndc signing -nsec3param 1 1 15 - zone. If the value would cause the serial number to go backwards it will be rejected. The primary use is to set the serial on inline signed zones.
Write server statistics to the statistics file. Display status of the server. Stop the server, making sure any recent changes made through dynamic update or IXFR are first saved to the master files of the updated zones. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search.
Master is updating a slave but very slowly, is there any way to speed this up? Is it possible to do update automatically? BIND is not monitoring file changes i. You must run rndc reload on the master after every modification. Sign up to join this community. The best answers are voted up and rise to the top.

I have two test servers master and slave: Master is updating slave but very slowly. How to speed this up. Master Thanks for the overflowing suggestions and replies. I tested it earlier by incrementing the serial number of a test zone in the primary, then reload the primary and the secondary both running BIND 8.
The secondary didn't update the zone until minutes later and it's unclear if the delay is a constant. That's why I want to force a refresh immediately instead of waiting "indefinitely". Remember the file will not necessarially be written immediately. You need to query the nameserver to determine if the zone has updated.
I remember seeing this behavior with the 9. How many master or servers do you have configured that are allowed to update the zone file?
When I had more then one I seen this. Bind would wait about 10 minutes fro the first one in the list to send the new zone file.
When this didn't happen it accepted the zone file from the other server. Reply to author. Report message as abuse. Show original message. Either email addresses are anonymous for this group or you need the view member email addresses permission to view the original message.
