Problem setting up sshd

General
1

Is there some special configuration to set up ssh/sshd on chachyos? I’ve done it many time on other arch-based systems, but I’m quite stuck:

  1. I’ve started sshd.service on the host m/c
  2. Ping to the host works fine.
  3. ssh to the host simply has no response:
❯ ssh cachyos-host -v
OpenSSH_9.9p1, OpenSSL 3.4.0 22 Oct 2024
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Reading configuration data /etc/ssh/ssh_config.d/20-systemd-ssh-proxy.conf
debug1: Connecting to cachyos-host [192.168.x.x] port 22.

Host Firewall? SSHD running? Router firewall?

Thanks Danny. I was sure that I had not set up any firewall, and my router has not firewall (since other sshd are running ok on the LAN). However I’ve just discovered that plasma network setting has enabled ufw by default… (blush).

ufw comes default on CachyOS :slight_smile:

Oh, I’ve been there…also been deep into sshd config too figuring out ‘why’.

So, I’m trying this too, but after allowing port 22 and ssh on ufw in both cachy machines I got, I still can’t seem to ssh into each other? (error “connection refused”)

Am I missing something else?

edit: I actually had to enable the ssh service :person_facepalming:
use “systemctl enable sshd” and reboot first.
