SSH Setup

This is basically notes to myself on how to get a basic ssh server running. I do this just too rarely that I’m comfortable doing it from memory.

Install ssh (however you like according to your platform)

Add and/or uncomment the following lines in /etc/ssh/sshd_config:

1
2
3
4
5
6
7


PermitRootLogin no
PasswordAuthentication no # (can be yes for low-risk stuff)
PermitEmptyPasswords no
ClientAliveInterval 1000 # not sure if this one is needed
ClientAliveCountMax 0 # disables inactive timeout
Port 1234 # (not port 22)
Port 4321 # (it's possible to expose more ports if desirable)

Start/restart the ssh service
On client, run:
```
ssh -p 1234 user@hostname-or-ip
```
