| Description |
|
fping finally seems to be picked up by a new maintainer - which is great (see http://fping.org/ ) the problem is that zabbix source ip detection breaks with fping3. zabbix tries to detect whether fping help output contains -I or -S flag (in that order), and uses that option with the source ip specified. unfortunately for zabbix, fping3 uses -I for source interface, and -I comes first in the fping3 help output, so zabbix picks it up and uses -I<sourceip>, which fails and makes fping3 to ignore this parameter this is true for both fping 3.0 and 3.1-rc1 (both already used in gentoo) |

as for how to properly solve this... hard to say. zabbix must be able to detect & work properly with vanilla fping2, patched with both flags and also fping3. maybe do 'fping -v' first, if it's >= version 3, use -S (until source interface is implemented in zabbix |

I am not sure it is a bug, it sounds like a feature request (improvement). |

...and it might get resolved in fping3, so only early fping3 versions might be affected. |

FreeBSD started to use v3.4 in its ports three (i.e. as stable branch) from 24 Sep 2012 09:16:00 Debian is using already v3.2 in testing repo and v3.4 in experimental repo. |

any update on this bug? We're still advising Gentoo Linux users to avoid using fping >= 3.0 with zabbix and have been for over 6 months..I'd like to get clarification if the problem still exists, whether it really is a problem or just a feature request, and/or what the long term solution will be.... |

there are no specific plans to support all functionality with fping3 yet. we'll probably get to that when most distributions in wide use will have migrated to it |

Information for users of Fedora and EPEL: EPEL5 and 6 only ship fping-2.4b2. This version doesn't support setting a source IP address. You've got to set up routing accordingly or mangle datagrams with iptables to manipulate the routing decision, if necessary. All maintained Fedora releases ship fping-3.5. We're avoiding the problem of flag detection by hard-coding the flag to -S. |

EPEL 7 will have fping 3.5 and the behavior thus will be the same as in Fedora. |

This seems to also affect Zabbix 2.4.4 release on Debian Wheezy. Debian uses fping version 3.2. The patch on http://pkgs.fedoraproject.org/cgit/zabbix.git/tree/zabbix-1.8.12-fping3.patch still seems to fix this. |

Attached "fping-help.txt" demonstrates help output for fping tags that are not release candidates (based on https://github.com/schweikert/fping). |

Fixed in development branch svn://svn.zabbix.com/branches/dev/ZBX-4894 by preferring "-S" option over "-I" option if both are present. |

Successfully tested. |

Fixed in pre-2.2.12rc1 r58772, pre-2.4.8rc1 r58773, pre-3.0.2rc1 r58774, pre-3.1.0 (trunk) r58775. |
), fallback to the existing detection otherwise ?
