Hi guys, i am using ubuntu 20.04 and ispconfig 3 i want to restart the sshd after changing the sshd_config and get an error: Code: tomdf@server3:~$ systemctl restart sshd Failed to restart sshd.service: Interactive authentication required. See system logs and 'systemctl status sshd.service' for details. then i look for the status of sshd and get Code: tomdf@server3:~$ systemctl status sshd ● ssh.service - OpenBSD Secure Shell server Loaded: loaded (/lib/systemd/system/ssh.service; enabled; vendor preset: e> Active: active (running) since Fri 2022-01-07 07:00:30 CET; 1 months 6 day> Docs: man:sshd(8) man:sshd_config(5) Main PID: 3581868 (sshd) Tasks: 7 (limit: 9485) Memory: 208.8M CGroup: /system.slice/ssh.service ├─ 51168 gpg-agent --homedir /var/lib/spamassassin/sa-update-keys> ├─3438812 sshd: tomdf [priv] ├─3438814 sshd: tomdf@pts/0 ├─3438815 -bash ├─3439355 systemctl status sshd ├─3439356 pager └─3581868 sshd: /usr/sbin/sshd -D [listener] 0 of 10-100 startups the syslog does not show any message do you have any idea how i can solve this? thank you for your help
