Mount Katahdin in Maine is the northern terminus of the famed Appalachian Trail. Ī ten-hour flight from Moscow, the city is the eastern terminus of the Trans-Siberian railroad.
Termius def upgrade#
If you have multiple Controllers, set them all in the Targets section of the upgrade script, which shows how easy it is to have Termius scale out for you.Now this cat is found primarily east of the Stanovoy Range near the Amur River's terminus, which is in what country.
Hopefully some others will get some use out of this, and can start building up a good snippet library to automate the still fairly clunky way of updating Unifi equipment and devices. Just plug them into the Targets section, and they'll have the upgrade script run on them as well, sharing the session variable(s).

If you have multiple Controllers, set them all in the Targets section of the upgrade script, which shows how easy it is to have Termius scale out for you. Here are some screenshots on how this looks in the Termius:
Termius def update#
No more looking up varying upgrade scripts when you need to update your Unifi devices. After that, run the upgrade scripts, and all targets of that script will be initialized with your session variables, and the installation commands will be run. Once an update is released, all you have to do is plug in the new installation URL endpoint in your startup snippets, and that's it.
Termius def download#
When you run the update snippet, it'll open SSH sessions to all 5, and as soon as those switches are opened, the startup script will initialize the session variables you need, which in this case is the download URL for the update package. For example, if you have a network with 5 Unifi switches, you can set those 5 as targets of a single snippet, and assign the session variable snippet as a startup snippet from the host property page in Termius. Where this type of automation really shines is that you can apply snippets to multiple hosts at the same time, so multiple Unifi devices can be assigned as targets of a single snippet/script. Here's an example for updating the Controller software:Ĭd /tmp wget $downloadUrl dpkg -i unifi_sysvinit_all.deb rm unifi_sysvinit_all.debĪs you can see, plugging in session variables is easy to do, and frees you from having to remember (or look up) the varying commands needed to upgrade different types of UI devices. Different types of Unifi equipment have different commands to upgrade the firmware, so in a 2nd script, you'll define the upgrade statements, and then plug in the downloadUrl as part of the installation script. When you first initiate an SSH connection to the Unifi equipment, this stores the URL variable for later reuse in the installation script. define other session variables you may need There's a workaround though, which is to create a snippet that gets run as a startup script (this is set in the host properties) for the host(s) you want to upgrade which defines the URL like the following (which we'll call a session URL):Įxport downloadUrl="". Storing variables in Termius is at first glance not possible. NanoHDs use the same firmware as FlexHDs, and almost all switches now use the USW-Multi installation package. Getting Termius itself set up is very easy to do, and how it's organized is fairly intuitive, although at first it seems to be lacking a mechanism for user defined variables, which in this overview is the ability to store firmware/software update URLs since those change with subsequent releases, but can applied to multiple hosts at the same time, e.g.
Termius def code#
The Termius client itself allows you to store SSH client connection info, SSH username/password/SSH keys, and bits of user defined code called Snippets. If you haven't used Termius before, it's an app used for SSH/Telnet sessions. This post assumes you've already set up login info for the SSN connections in the Keychain section of Termius. For non-trivial Unifi deployments, tools like Termius are essential to automate the updates. Automating your Unifi equipment updates can be a chore, which is why tools like Termius exist: To automate tasks via SSH/CLI, and Termius is great for this as there are Termius clients for virtually every platform, including mobile (iOS, Android).
