Negative, I have Raspbian with version 12 bookworm installed on other Pi 3b and can successfully change sshd listen port. Even armbian-config doesn't allow an alternate port. The problem requires a fix in Armbian.

Same here ... I installed Armbian_24.5.1_Odroidxu4_bookworm_current_6.6.31_minimal.img today, along with a few other tools I regularly use: root@odroidxu4:~# grep "Port " /etc/ssh/sshd_config #Port 22 Port 61022 root@odroidxu4:~# systemctl restart ssh root@odroidxu4:~# systemctl status ssh | grep listening Jun 10 23:03:06 odroidxu4 sshd[1309]: Server listening on :: port 22. root@odroidxu4:~# lsof -nPi | grep ssh | grep -v grep sshd 1149 root 4u IPv6 16682 0t0 TCP 192.168.1.6:22->192.168.1.53:42810 (ESTABLISHED) sshd 1309 root 3u IPv6 7753 0t0 TCP *:22 (LISTEN) How to effectively change sshd port with newest Armbian, please? These same steps worked in Armbian_21.05.4_Odroidxu4_buster_legacy_4.14.222.img, just as they have in every other Linux distribution. I tried to follow samond's solution, but still no altered sshd port: root@odroidxu4:~# cat /etc/systemd/system/sshd.socket [Socket] ListenStream= ListenStream=61022 root@odroidxu4:~# systemctl daemon-reload && systemctl enable sshd.socket && systemctl start sshd.socket The unit files have no installation config (WantedBy=, RequiredBy=, Also=, Alias= settings in the [Install] section, and DefaultInstance= for template units). This means they are not meant to be enabled using systemctl.
