That is not as simple as that -- we lived with "simple" for long time, but it was not covering some corner cases so we ended up using the sd_notify, since that was the only reliable way for systemd to know the service is working. For others interested in this topic, there was a long discussion in bug #2641, unfortunately without upstream solution: https://bugzilla.mindrot.org/show_bug.cgi?id=2641 Regards, -- Jakub Jelen Software Engineer S...

Latest Oracle Linux (7.5) and openssh 7.4 is bundled as an rpm. this runs fine. if I download openssh 7.6 or 7.7, compile it with the flags --with-pam and --with-pid-dir=/var/run and install it to /usr/local, modify the sshd.service file to point to /usr/local/sbin/sshd, the start hangs. The sshd.service files looks like this: [Unit] Description=OpenSSH server daemon Documentation=man:sshd(8)

I didn't say that, and I don't agree with that, to me it's welcome ambition rather than bad assumptions. Consider this: How could systemd determine whether startup of a foreground daemon completed successfully or failed? Other than explicit

Hi, Am rebuilding httpd from scratch to enable http2 and minimize extra modules on Cent Os 8. Am having trouble understanding the spec file [0] and systemd initialization [1][2][3] (these are very similar to those extracted from [4]). Why are 3 scripts needed to start the service and why is a pid setting not needed as used in the httpd.service file at [5]? Benson [0]

Hi everybody, I've set up an new CentOS 7.6.1810 server. Then, via yum I installed qemu-kvm libvirt libvirt-python libguestfs-tools virt-install. There were no problems. But when I try to systemctl start libvirtd I get the following message: "libvirtd: process 472: arguments to dbus_message_iter_append_basic() were incorrect, assertion "_dbus_check_is_valid_utf8 (*string_p)"

...eports no error, while sshd isn't running. So what to do? A workaround for [re]start is to add sshd -t ExecStartPre linting, but that doesn't help at all with reload. It would be good to have sshd integrate with systemd here, but we need to avoid the libsystemd dependency. Fortunately, sd_notify() doesn't need to do all too much; almost everything is used before in the OpenSSH codebase, so it's easy enough to add local code for it. It's a sendmsg() with SCM_CREDENTIALS to the AF_UNIX SOCK_DGRAM named in $NOTIFY_SOCKET. The file descriptor passing code in monitor_fdpass.c sends...

...otify instead of Type=forking. While it's possible for systemd to keep track of all the subprocesses of a forking daemon, its difficult to determine if the service is "started". It uses the Pid file for that. With Type=notify, the daemon will send a notification back to systemd via sd_notify() when it is up, which makes it easier for systemd to know when a service has started, and start any dependencies or established that a target has been reached. You need a service that supports Type=notify, which httpd does. -- Jonathan Billings <billings at negate.org>

Ok I created my script this morning [Unit] Description=Connections After=network.target [Service] Type=notify ExecStart=/home/silentm/bin/mystart [Install] WantedBy=multi-user.target I put it in the correct directory, I rebooted and I see that my mystart script runs- programs start up but then they are killed with signal 15... Is there something else that allows them to continue to run? the

Under some circumstances for debugging purposes it may be helfpfull to know the PID used during startup as well. Just noted that this one is only listen in forked mode. Samba does fork with type=notify as well but systemd is waiting for sd_notify message in that mode. Anyway, for curiosity i recompiled samba with --without-systemd. If i use type=notify mode now and no PIDFile, systemctl start samba-ad-dc does not start samba but it shows the starte PID. There is an leftover samba process running whom can be killed with -9. root at dc1:...
