I've just needed to ssh into a VPS to fix something pretty urgently but my laptop was on the fritz and held me up. Obviously a big single point of failure problem!<p>I don't have any other physical machines that I could give ssh key access as backup..<p>There must be a web-based personal terminal provider that you can set up on a permanent basis? Then you could access it from anywhere, even when out with mobile etc. But I'm not sure which to go with/trust.<p>Or do most people just have a cheap secondary laptop?
I use android phone with termux or juicessh and hacker keyboard app. Also pretty much every phone should work with tiny foldable Bluetooth keyboard.<p>If you want a mobile kit for hotel room without carrying laptop there you can try some HDMI screen mirroring dongle (Google Cast).
There are a lot of potential security problems with setting something like what you describe, but it is very possible.<p>If you wanted, you could run <a href="https://github.com/huashengdun/webssh" rel="nofollow">https://github.com/huashengdun/webssh</a> on the sever you are trying to access, or something equivalent to a Boston server.
This is something you should definitely host with TLS, and some form of authentication.<p>You could use something like this: <a href="https://github.com/PHPAuth/PHPAuth" rel="nofollow">https://github.com/PHPAuth/PHPAuth</a>
You could also use Okta.
I built my own, Using codemirror.<p>NodeJs for the server which spawns a process to execute bash commands.<p><a href="https://twitter.com/fasturdotcom" rel="nofollow">https://twitter.com/fasturdotcom</a>
I use my phone. I have termux on android, with password protected ssh-key and it did save me a few times.<p>I assume there is something like that for iOS, or other phones.
