Domino on Linux: Updated/additional lnsnmp Start/Stop-Script that is compatible with systemd based Linux OS

Currently, there is only a lnsnmp.sh Script (/opt/ibm/domino/notes/latest/linux/lnsnmp.sh) shipped with Domino that does not work with systemd based Linux OS like CentOS 7 / RHEL 7). 

The Documentation ( https://www.ibm.com/support/knowledgecenter/de/SSKTMJ_10.0.1/admin/admn_configuringthedominosnmpagentforlinux_t.html () works only for SysVinit-based older CentOS / RHEL Releases).

    Does SNMP work for you outside the container in Domino 12.0.2?
    I can't get it working on current servers. I even used strace to trace the lnsnmp process.


    The SNMP server on the host is running and I get this back before the process terminates.

    Even if we solve it, it's not clear if we can get it working in combination.

    We need lnsnmp probably running inside the container. Or maybe it would be OK to run it on the host?

    I tried right now on a normal server and failed. Does it need to be installed inside the container?
    Could it run on the container host and the Domino servertasks communicate with it on the host?

    Still you would need a systemd service - which would not be too complicated to build.

    But I don't get it working even I traced it with strace. Any tip what might be missing?

    It was trying to read a lnsnmp.ini file in various places. but that's just optional. Even with debug enabled -D 255 I see only the output below and no errors.

    It's simple to make systemd service, but the lnsnmp.sh script does not work with systemd based Linux OS.

    systemd[1]: Starting LNSNMP(SNMP) Daemon....
    lnsnmp.sh[36098]: Don't know how to start/stop lnsnmp on this version of Linux.
    systemd[1]: lnsnmp.service: Control process exited, code=exited status=1
    systemd[1]: Failed to start LNSNMP(SNMP) Daemon..
    systemd[1]: lnsnmp.service: Unit entered failed state.
    systemd[1]: lnsnmp.service: Failed with result 'exit-code'.

    Also the lnsnmp.sh contains old default path which hasn’t been used in many years.

    Daniel Nashed created such a tool for UNIX/Linux.  See:

    http://www.nashcom.de/nshweb/pages/startscript.htm

    Very simple to set up and use. It just works!!  I have it on all my Linux Domino servers.

    As discussed on https://atnotes.de/index.php/topic,61967.0.html Ulrich Krause posted an service-Definition for lnsnmp that could be used directly (or as a base) for Shipping with Domino:

     

    [Unit]
    Description=LNSNMP
    After=network.target

    [Service]
    Type=simple

    LimitNPROC=infinity
    LimitCORE=infinity
    Environment=PATH=/usr/bin:/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin
    PIDFile=/var/run/lnsnmp.pid

    ExecStart=/opt/ibm/domino/notes/latest/linux/lnsnmp

    [Install]
    WantedBy=multi-user.target

Domino 10/11 SNMP systemd support

Domino SNMP consists of servertasks in combination with a Linux deamon. The script to start the Linux component still use init.d! Domino 10 is only supported on RHEL/CentOS 7.4 and higher and SLES 12 and higher. Both switched from init.d to system...
