To be able to respond confidently to server alerts even on holidays, I installed the SSH client app JuiceSSH.
・JuiceSSH - SSH Client - Android Apps on Google Play
I installed it on my Nexus5, but since it can’t take an SD card, I copied and pasted the SSH private key via email.
Otherwise, the UI is intuitive, so I could set up connection destinations without any particular trouble.
That’s all from the Gemba.
