+ It brings sd-daemon.c and .h directly downloaded from systemd. I've made very |
|
11 |
+ few changes to it to match our NETSNMP_NO_SYSTEMD and include paths. |

+ Add sd_find_inet_socket() and sd_find_inet_unisx() helpers into |
|
24 |
+ system-specific code. This will help us to find various sockets |
|
25 |
+ created by systemd much easier. |

+ Check sockets created by systemd when opening new server sockets. |
|
32 |
+ |
|
33 |
+ systemd can pass sockets to our daemons during startup using LISTEN_FDS |
|
34 |
+ environment variable. So check this variable when opening new listening |
|
35 |
+ socket - maybe system has already opened the socket for us. |

|
391 |
++ Reference implementation of a few systemd related interfaces for |
|
392 |
++ writing daemons. These interfaces are trivial to implement. To |
|
393 |
++ simplify porting we provide this reference implementation. |
|
394 |
++ Applications are welcome to reimplement the algorithms described |
|
395 |
++ here if they do not want to include these two source files. |
|
396 |
++ |
|
397 |
++ The following functionality is provided: |
|
398 |
++ |
|
399 |
++ - Support for logging with log levels on stderr |
|
400 |
++ - File descriptor passing for socket-based activation |
|
401 |
++ - Daemon startup and status notification |
|
402 |
++ - Detection of systemd boots |
|
403 |
++ |
|
404 |
++ You may compile this with -DDISABLE_SYSTEMD to disable systemd |
|
405 |
++ support. This makes all those calls NOPs that are directly related to |
|
406 |
++ systemd (i.e. only sd_is_xxx() will stay useful). |
|
407 |
++ |
|
408 |
++ Since this is drop-in code we don't want any of our symbols to be |
|
409 |
++ exported in any case. Hence we declare hidden visibility for all of |
|
410 |
++ them. |
|
411 |
++ |
|
412 |
++ You may find an up-to-date version of these source files online: |
|
413 |
++ |
|
414 |
++ http://cgit.freedesktop.org/systemd/plain/src/sd-daemon.h |
|
415 |
++ http://cgit.freedesktop.org/systemd/plain/src/sd-daemon.c |
|
416 |
++ |
|
417 |
++ This should compile on non-Linux systems, too, but with the |
|
418 |
++ exception of the sd_is_xxx() calls all functions will become NOPs. |
|
419 |

552 |

|
553 |
++ readable error message. Example: "STATUS=Completed |
|
554 |
++ 66% of file system check..." |
|
555 |
++ |
|
556 |
++ ERRNO=... If a daemon fails, the errno-style error code, |
|
557 |
++ formatted as string. Example: "ERRNO=2" for ENOENT. |
|
558 |
++ |
|
559 |
++ BUSERROR=... If a daemon fails, the D-Bus error-style error |
|
560 |
++ code. Example: "BUSERROR=org.freedesktop.DBus.Error.TimedOut" |
|
561 |
++ |
|
562 |
++ MAINPID=... The main pid of a daemon, in case systemd did not |
|
563 |
++ fork off the process itself. Example: "MAINPID=4711" |
|
564 |
++ |
|

++Net-SNMP provides two daemons, which support systemd system manager. |
|
658 |
++See http://www.freedesktop.org/wiki/Software/systemd to learn how |
|
659 |
++systemd works. Both socket activation and notification is supported by these |
|
660 |

661 |

++snmpd - The SNMP agent |
|
666 |
++---------------------- |
|
667 |
++Socket activation od snmpd daemon is implemented, but it's discouraged. |
|
668 |
++The reason is simple - snmpd not only listens and processes SNMP requests |
|
669 |
++from network, but also gathers system statistics counters, sends traps and |
|
670 |
++communicates with subagents. It even opens few netlink sockets. |
|
671 |
++ |
|
672 |
++In other words, snmpd should run from system start to properly work. |
|
673 |
++This can be done in two ways: |
|
674 |
++1) either as snmpd service unit with 'Type=notification' and without a socket |
|
675 |
++ unit |
|
676 |
++2) or as snmpd service unit with 'Type=simple', appropriate socket socket unit |
|
677 |
++ and the snmpd service enabled. This way systemd creates the snmpd listening |
|
678 |
++ socket early during boot and passes the sockets to snmpd slightly later |
|
679 |
++ (but still during machine boot). This way systemd can paralelize start of |
|
680 |
++ services, which depend on snmpd. Admins must adjust the socket file manually, |
|
681 |
++ depending if the snmpd support AgentX, IPv6, SMUX etc. |
|
682 |
++ |
|
683 |
++snmpd should be started with '-f' command line parameter to disable forking - |
|
684 |
++systemd does that for us automatically. |
|
685 |
++ |
|
686 |
++ |
|
687 |
++snmptrapd - The trap processing daemon |
|
688 |
++-------------------------------------- |
|
689 |
++snmptrapd supports full socket activation and also notification (if needed). |
|
690 |
++Both 'Type=simple' (with appropriate socket unit) and 'Type=notify' services |
|
691 |
++will work. Again, '-f' parameter should be provided on snmptrapd command line. |
|
692 |
++ |
|
693 |
++If integration with SNMP agent using AgentX protocol is enabled, snmptrapd should |
|
694 |
++start during boot and not after first SNMP trap arrives. Same rules as for snmpd |
|
695 |
++applies then. |
