On installing Raspotify on a new build of Ubuntu 19.10 for Raspberry Pi I saw the following error: Raspotify installer only runs on a Raspberry Pi Not too much information there. Going through the manual install procedure you end up something more meaningful: N: Skipping acquire of configured file ‘main/binary-arm64/Packages’ as repository ‘https://dtcooper.github.io/raspotify raspotify InRelease’ doesn’t support architecture ‘arm64’ So unpacking that a bit it seems that in switching to using Ubuntu Server from Raspbian on my Linux Spotify connect Raspberry Pi’s the architecture is ARM64 (ARMv8) rather than using armhf.
This is my process for upgrading HA Palo Alto firewalls. Some steps will depend on your HA configuration; if you are not using preemption then you can’t disable it etc. So where possible refer to the official documentation. To start off you should take named snapshots of the config and export them off the firewall just to be safe. Below are the steps: Primary Disable preemption, commit Fail over the firewall, CLI: request high-availability state suspend Note this will fail over the firewall Check connectivity now the secondary is active Install update and reboot After device has rebooted log in and check the tasks for a successful autocommit, CLI: show jobs all Enable HA, CLI: request high-availability state functional Secondary
Since Ubuntu 17.10 Artful, ifupdown has been replaced with Netplan. After each session trying to remember how to configure Netplan I seem to forget the locations and syntax. So this is for my aging memory. The configuration files for Netplan live in: /etc/netplan/ The default install of Ubuntu 18.04 leaves the following file: /etc/netplan/50-cloud-init.yaml As you can see the config file is in yaml. Unless specified manually the default install will give a simple file using DHCP.
The Palo Alto Networks Logging Service enables firewalls to push their logs to Cortex Data Lake (CDL). If a firewall is having issues connecting you can try the following. Check the logging service license is installed: request license info You should at least see the logging service license among the returned licenses. If not then things are not going to work. If the license is there and you still have issues then try the following to refresh the key and the certificate.
Trying to remember something I previously knew; how to insert images into posts. Using VS Code on macOS and the Paste Image extension you can copy the image into the clipboard using cmd + ctrl + shift + 4 Once in the clipboard you can paste the image into VS Code using cmd + alt + v. See below: Paste Image will copy the file into a folder and create the link in markup.
As of the Windows 10 October 2018 update, installing the Remote Server Administration Tools (RSAT) has changed: Starting with Windows 10 October 2018 Update, RSAT is included as a set of “Features on Demand” in Windows 10 itself. See “Install Instructions” So rather than a separate download RSAT has joined features on demand. This is an improvement in my opinion as the install is closer tied to the OS. Previously you would have to wait for the tools to be updated for newer versions of windows and that did not seem to happen very quickly.
2019 and a brand new post. Things have moved on so it is time to move to something new. In this case out with Jekyll and in with Hugo! So this calls for a brand new page. I guess I’m going to have to workout markup~~…~~
Configuration files can be long and complex and it is hard to see which values have been set. There are numerous ways to do this however, grep with -v (–invert-match) is a quick way to achieve this. The following example removes all the comments from an elasticsearch configuration file: [email protected]:~$ sudo grep -v ‘#’ /etc/elasticsearch/elasticsearch.yml Which returns: cluster.name: es node.name: es01 network.host: 10.1.10.187 discovery.zen.ping.unicast.hosts: ["10.1.10.187", "10.1.10.124"] discovery.zen.minimum_master_nodes: 2 Five lines where it is easy to see what has been configured.
Update Note, if you are looking to search for DHCP information across all or multiple DHCP servers in the forest then this is a quicker method. The below is still valid if you are searching a single server. Sometimes in a large infrastructure it can be hard to find new devices added to the network. Being able to search on MAC address across all DHCP scopes comes in handy. With powershell and Windows DHCP server this is easy to do.
You can pull this information from wmi. This method is useful when you are on the other side of the world to the machine you are working on. All you need is a local or remote shell via psexec or powershell, and type the following: wmic csproduct get name Here are some sample results: Name HP Z420 Workstation Name PRIMERGY BX924 S4 Name ProLiant DL380 G7
