This utility allows management of the named DNS daemon. Do this on the master server only. As you can see, there is a file called rndc. This is the default directory where BIND expects to find its config files and zones. Now, copy this file to the second server in the same location. What matters is that you have to change the permissions and the owner of the file. BIND runs under the bind user, not root. Do this on both servers. To control the slave server from the master, we have to modify the main BIND configuration file, named.
Also, the keys have to be the same, but we already took care of that part above. Do this on the slave server, not the master. If you look at my IPs below, this means that the rndc utility will be accepted from the localhost and from the the IP By default, it listens on the localhost only. Do this on BOTH servers. In named. You should put the public IP of each server there, so the line will differ on both servers. If you have a firewall, make sure port TCP is open for communication.
If we try to ping google. From another computer, try to use any of our servers as a DNS. This is what you should get: Query refused. But, also, we want to access the Internet from the server, for example to update the server. Name resolution for other domains from localhost is OK, but not OK from outside. The zone file tells where the records can be found. On the master server only, edit named. We are allowing the transfer of the zones to the slave server only.
Go all the way at the bottom and add these line to define the zone file. The file should be called db. You might want to read the following link if you are not familiar with the syntax of a zone file. All you have to do now is to reload the new config with rndc reload. This enables the ipfw firewall which is needed for natd. Thank you for reading. Good Day Amos Thanks for your brilliant work. Will this config work on freebsd 12 inside an iocage jail.
I am moving away from linux and implementing my customer service platform on Freebsd only going forward. Best Regards Johan van Huyssteen. You can check here. Wondering about the android openvpn app.
My apologies — worked it out. There are two difference OpenVPN apps. The latter allows you to import certificates. Update maybe? This was my openvpn server hierarchy:. You may need to restart your freenas server after setting this parameter. FreeBSD security patches may be downloaded and installed using the following commands. The first command will determine if any outstanding patches are available, and if so, will list the files that will be modifed if the patches are applied. The second command will apply the patches.
If the update applies any kernel patches, the system will need a reboot in order to boot into the patched kernel.
If the patch was applied to any running binaries, the affected applications should be restarted so that the patched version of the binary is used.
Usually, the user needs to be prepared to reboot the system. To know if a reboot is required by a kernel update, execute the commands freebsd-version -k and uname -r and if it differs a reboot is required.
If patches exist, they will automatically be downloaded but will not be applied. The root user will be sent an email so that the patches may be reviewed and manually installed with freebsd-update install.
If anything goes wrong, freebsd-update has the ability to roll back the last set of changes with the following command:. Again, the system should be restarted if the kernel or any kernel modules were modified and any affected binaries should be restarted.
If a custom kernel is installed, it will have to be rebuilt and reinstalled after freebsd-update finishes installing the updates. The uname 1 command may be used to verify its installation. It will be helpful in diagnosing a variety of problems and in performing version upgrades. Rebuilding and reinstalling a new custom kernel can then be performed in the usual way.
The updates distributed by freebsd-update do not always involve the kernel. It is not necessary to rebuild a custom kernel if the kernel sources have not been modified by freebsd-update install. The current patch level, as indicated by the -p number reported by uname -r , is obtained from this file. Rebuilding a custom kernel, even if nothing else changed, allows uname to accurately report the current patch level of the system.
This is particularly helpful when maintaining multiple systems, as it allows for a quick assessment of the updates installed in each one. X to FreeBSD Both types of upgrades can be performed by providing freebsd-update with a release version target.
After the command has been received, freebsd-update will evaluate the configuration file and current system in an attempt to gather the information necessary to perform the upgrade. A screen listing will display which components have and have not been detected. For example:. At this point, freebsd-update will attempt to download all files required for the upgrade. In some cases, the user may be prompted with questions regarding what to install or how to proceed.
This warning may be safely ignored at this point. Once all the patches have been downloaded to the local system, they will be applied. This process may take a while, depending on the speed and workload of the machine.
Configuration files will then be merged. The merging process requires some user intervention as a file may be merged or an editor may appear on screen for a manual merge. The results of every successful merge will be shown to the user as the process continues. A failed or ignored merge will cause the process to abort. The system is not being altered yet as all patching and merging is happening in another directory. Once all patches have been applied successfully, all configuration files have been merged and it seems the process will go smoothly, the changes can be committed to disk by the user using the following command:.
The kernel and kernel modules will be patched first. Before rebooting with the GENERIC kernel, make sure it contains all the drivers required for the system to boot properly and connect to the network, if the machine being updated is accessed remotely. It is recommended to disable non-essential services as well as any disk and network mounts until the upgrade process is complete. Once the system has come back online, restart freebsd-update using the following command.
Since the state of the process has been saved, freebsd-update will not start from the beginning, but will instead move on to the next phase and remove all old shared libraries and object files.
Depending upon whether any library version numbers were bumped, there may only be two install phases instead of three. The upgrade is now complete. If this was a major version upgrade, reinstall all ports and packages as described in Upgrading Packages After a Major Version Upgrade.
If a custom kernel has been built more than once or if it is unknown how many times the custom kernel has been built, obtain a copy of the GENERIC kernel that matches the current version of the operating system. It is also suggested that the kernel is built without any other special options. Generally, installed applications will continue to work without problems after minor version upgrades.
After a major version upgrade, all installed packages and ports need to be upgraded. Packages can be upgraded using pkg upgrade. A forced upgrade of all installed packages will replace the packages with fresh versions from the repository even if the version number has not increased.
The forced upgrade can be accomplished by performing:. This command will display the configuration screens for each application that has configurable options and wait for the user to interact with those screens. To prevent this behavior, and use only the default options, include -G in the above command.
Once the software upgrades are complete, finish the upgrade process with a final call to freebsd-update in order to tie up all the loose ends in the upgrade process:. This command evaluates the current version of system utilities, libraries, and configuration files and can be used as a built-in Intrusion Detection System IDS. As freebsd-update stores data on disk, the possibility of tampering is evident. While this possibility may be reduced using kern.
An alternative method for providing IDS functionality using a built-in utility is described in Binary Verification. The system will now be inspected and a lengthy listing of files, along with the SHA hash values for both the known value in the release and the current installation, will be sent to the specified output file.
The entries in the listing are extremely long, but the output format may be easily parsed. For instance, to obtain a list of all files which differ from those in the release, issue the following command:. This sample output has been truncated as many more files exist. Some files have natural modifications. Kernel modules may differ as freebsd-update may have updated them.
Documentation is an integral part of the FreeBSD operating system. The initial download of the documentation sources may take a while. Let it run until it completes. This section provides an explanation of each branch and its intended audience, as well as how to keep a system up-to-date with each respective branch.
Members of the FreeBSD community who are active testers. They are willing to spend time solving problems, making topical suggestions on changes and the general direction of FreeBSD, and submitting patches. Users who wish to keep an eye on things, use the current source for reference purposes, or make the occasional comment or code contribution. It is not a quick way of getting bug fixes as any given commit is just as likely to introduce new bugs as to fix existing ones. The Commit messages for the main branch of the src repository list records the commit log entry for each change as it is made, along with any pertinent information on possible side effects.
To join these lists, go to FreeBSD list server , click on the list to subscribe to, and follow the instructions. Due to the size of the repository, some users choose to only synchronize the sections of source that interest them or which they are contributing patches to. Be active! Suggestions with accompanying code are always welcome.
It is simply another engineering development track, not a resource for end-users. Users who do not have the resources to perform testing should instead run the most recent release of FreeBSD. Developers will also make announcements in this mailing list when they are contemplating some controversial fix or update, giving the users a chance to respond if they have any issues to raise concerning the proposed change.
Join the relevant git list for the branch being tracked. This list records the commit log entry for each change as it is made, along with any pertinent information on possible side effects. In order to track changes for the whole source tree, subscribe to Commit messages for all branches of the src repository.
Refer to www. When tracking down bugs it is important to know which versions of the source code have been used to create the system exhibiting an issue. FreeBSD provides version information compiled into the kernel. The git rev-list command is used to find the n-number corresponding to a Git hash. Usually this number is not all that important.
