Logs are a critical component of any software or operating system. One of the most widely used logging systems on Linux systems is rsyslog. It has evolved from a regular syslog daemon to a fully-featured, enterprise level logging system. Most Linux distributions come with the rsyslog package preinstalled. By default, rsyslog uses the imjournal and imusock modules for importing structured log messages from systemd journal and for accepting syslog messages from applications running on the local system via Unix sockets, respectively.
If you want to use a UDP connection, which is faster but unreliable, search and uncomment the lines below replace with the port you want it to listen on, this should match the port address that the clients send messages to, we will look at this more when configuring a rsyslog client. To use TCP connection which is slower but more reliablesearch and uncomment the lines below. Next, you need to define the ruleset for processing remote logs in the following format.
We will use the following ruleset for collecting logs from remote hosts, using the RemoteLogs template. Note that these rules must come before any rules for processing local messages, as shown in the screenshot. There are many other templates that you can use, for more information, see the rsyslog configuration man page man rsyslog.
Save and close the configuration file. To apply the recent changes, restart rsyslog daemon with the following command. Now verify the rsyslog network sockets. Use the ss command or netstat with the same flags command and pipe the output to grep to filter out rsyslogd connections. Next, on CentOS 7if you have SELinux enabled, run the following commands to allow rsyslog traffic based on the network socket type.
Now on the client system, check if the rsyslog service is running or not with the following command. Once the rsyslog service is up and running, open the main configuration file where you will perform changes to the default configuration.
To force the rsyslog daemon to act as a log client and forward all locally generated log messages to the remote rsyslog server, add this forwarding rule, at the end of the file as shown in the following screenshot.
The above rule will send messages from all facilities and at all severity levels. To send messages from a specific facility for example authuse the following rule. Save the changes and close the configuration file. To apply the above settings, restart the rsyslog daemon. Run a ls command to long listing of the parent logs directory and check if there is a directory called ip You may also want to refer to relevant rsyslog manual pages for more help.

Ask Ubuntu is a question and answer site for Ubuntu users and developers. It only takes a minute to sign up. Now while I am able to manage ugprades of Unifi the dependency is not really strick on it I am unable to use apt upgrade anymore for the remaining packages.
Is there a way to "skip" unifi and it's dependency upgrades since I already do manual upgrades of Unifi and tell apt upgrade everything else ignoring what Unifi is saying? To clarify. If you upgrade just like I did to To fix it, I've uninstalled Unifi, reinstalled Unifi and brought the configuration from backup and it works fine on 3. My guess is that Ubiquiti doesn't have this process automated for the remaining users so for stable release they added this dependency.
Now since I'm already upgraded I need to keep my machine up to date. So now I need to skip Unifi upgrades i install them from dpkg directly with skip dependenciesbut keep upgrading other stuff. While all good answers I've opted for different approach.
Why fix Ubuntu while I can fix Unifi package! And simply install dpkg -i unifi-fixed. After installation apt updateapt upgrade works! You have a package unifi with unmet dependencies. The Apt packaging system considers unmet dependencies to be a big problem and will keep complaining about it until it is solved. There is no other way to stop it. Ubuntu Community Ask!

Try to run sudo apt update first to update the reopistory database on your machine. And, if the problem don't go away run sudo apt --fix-broken install as the output suggest. Doesnt help. I always do that. Unifi blocks it because it requires 3.
The problem I've got is that I get numerous dependency problems when trying to install the software. In the guide, I get to the point where I run the command below when I run into errors:. I've tried purging and removing anything and everything to do with mongodb and I still get this same problem at the end. Need some advice on how to get this fixed. I am having the same issue, which is the mongodb-server has to be LESS than 3.
I believe these instructions should work for you, which adds sources to install an "older" version of mongodb-server and the unifi controller:. The easiest way is to follow steps on the site of Ubiquiti. Before you install it though, download and install mongodb community version 3. I took the one for Ubuntu Ubuntu Community Ask!

Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference.This article is based on my 15 Minute Hosted UniFi Controller setup, so start with that article, and then come back to this article when your UniFi Controller is up and running. Something like unifi. If anyone browses directly to those services, they will get a connection refused response. Log into your UniFi controller and run the following commands to allow those ports through the firewall:.
This command will ask for your email and FQDN — it will also have you accept the terms of usage. Your certificate and chain…. A developer named Steve Jenkins create a really great script that automates the rest of the process, making it super easy.
The first command renews the certificate every 12 hours on the hour, and the second command re-runs the UniFi script 5 minutes later. Very helpful. Once the cert is within X number of days of expiring I forget what X is — maybe 30 daysthen it renews.
Otherwise, all is well. I have not checked on ubuntu, but it might be unnecessary to create a renew crontab. The default for that crontab is also once every 12 hours. Seems like unnecessary downtime, especially if you are using features that require the controller to be online, like guest portal. Rather than opening 80 and all the time, you should use this command in your renewal command in crontab.
This will open the ports as certbot runs the renewal then automatically close the ports when it finishes. Wondering this myself. More than willing to add, but also have an additional question.
I have been wanting to do that with the controller and unifi video server as well.
Is there any other way to get this done? Thanks for this. Attempting this, but would love some help. Is this still an issue?Karhu ram test
I want to start an installation using the CloudKey on a new implementation and was wondering if this is going to work.
First: Thanks for the script. I know this an a few more but knowing that it is tested was a good thing. There seems to be nothing in the script preventing it from just running through everytime. So it will restart your controller twice a day!! Thank you! I followed all the steps, but I believe the script is defective. Can you verify this? Thank you.
So, I ran into a problem with this script and I figured out the solution. I am running Debian 9. LifecycleException: Protocol handler start failed — Caused by: java.
IllegalArgumentException: No aliases for private keys found in key store and more. There were no keys in the Keystore, so I restored the keystore. I scrolled back in the SSH buffer from the LetsEncrypt script and found I did not see this while the script was running : — keytool error: java.
Voila, everything is up and running.This tutorial will show you how to install a UniFi controller on Ubuntu. First we will configure the firewall using ufw and secure our server before installing UniFi. For this example, we are using Ubuntu The port below has nothing to do with UniFi but is required if you want to connect to your server using SSH.
If you changed your SSH connection port to something else than the standard 22, change it to the appropriate port.

If you are using OpenSSH, you can also configure the firewall based on the application. To do so, type:. To separate our UniFi repository, we are going to create a new repository by typing the following command:. If you want to know which version will be installed, take a look at the UBNT Support post for the latest information.
Have some patience while your server is installing the UniFi controller. When done, leave the server some time to start all the necessary programs min depending on your server. The UniFi controller is managed using a web interface. Open up your favorite browser and navigate to:. During installation, a self-signed certificate is installed. This will cause your browser to show a warning.
Install the UniFi controller on Ubuntu 16.04
Just accept the self-signed certificate for now, you can always install a supported certificate later to remove the warning. If you want to install an SSL certificate for use with the UniFi controller, go to my tutorial for help with the installation. You are commenting using your WordPress.

Ubiquiti's UniFi controller is a great way to manage networks built on Ubiquiti infrastructure. As a service provider, you may wish to host a centralized controller in the cloud so that you can manage multiple networks from a single location.
This how-to demonstrates how you might go about deploying Ubiquiti UniFi on a DigitalOcean droplet for easy scalability.
After logging in to the DigitalOcean dashboardclick the Create button and choose Droplets from the expanding menu. Under Choose a sizeselect a size that fits your budget. The smallest size should be just fine to get started. It's easy to scale your application up as you grow. Under Choose a datacenter regionselect a region that is close to you and your clients.
Under Select additional optionsselect both Backups and Monitoring. These free addons are important for any production system. If you choose not to use SSH authentication, you can still log in to your droplet using a username and password but SSH is the preferred method because of its increased security. More information about SSH logins can be found here. Under Finalize and createassign your droplet and appropriate name and click the Create button.
Once your droplet is created, its details can be viewed in your droplets list. Make a note of the IP address that has been assigned to your droplet. You'll need this later along with the temporary password that you will receive in your welcome email.

Windows users are recommended to use the free PuTTY tool. Pay special attention the the IP address.La cumparsita
Make sure that it matches the IP address of your new droplet. Log in using the username root and the password that was supplied to you. When logging in for the first time, you will be required to set a permanent password for your root account. Once you have done this, you will be logged in to your droplet and you will have a root prompt. PuTTY will also warn you that it does not recognize the certificate for the server your are connecting to.
