Is Termius the only cross platform emulator that includes Android as one of the platforms? It is quite good, in my limited experience, but too expensive for a hobbiest. I like that I can use my Linux desktop, MacOS laptop, and Android tablet/phone and the UX is the same across them all. The sync (trial for free, then charge) is great. But I'd be fine if it was something where I could DIY a sync method with something like Syncthing.
I'm aware of the likes of Alacritty, but no mobile app. And of course Termux is great for mobile, but no desktop versions.
It all boils down to wanting some sort of sync function either DIY or otherwise that includes hosts and SSH keys and while not as important, I do like the consistent UX between platforms. Is there something else to consider?
You bring some valid points up. Considering the low number of servers and clients I might need to reach, a sync certainly isn't critical. I sought it out because I started distro-hopping when I built my first dedicated Linux PC recently and was annoyed having to set up the password-less logon to the servers I use. Now that I've settled, it's not a concern anymore. And if I do want to try another down the road, I can make sure to back up the config files and import them in the new OS.
I actually lied. I said that OpenSSH doesn't have a "bookmarking" feature. OpenSSH does have a "bookmarking" feature – the Host entries in ~/.ssh/config, with a Hostname field.
I haven't used that feature much, since normally, I'd rather add a short hostname to /etc/hosts, and then all software on the system can use that short hostname, not just OpenSSH.
The last time I used it was to set up a tunnel that bounced through multiple machines running ssh servers with a single command, over a decade ago, which is something else it can do.
But it is there.
How dare you!
In all seriousness that's good to know. Gives me options to pick from. Thanks!
