#42474: munin: all plugins fail with "can't drop privileges: setrgid() not implemented at /opt/local/lib/perl5/site_perl/5.12.4/Munin/Node/OS.pm line 261" ------------------------------+-------------------------------- Reporter: pierre.bauduin@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.2.1 Keywords: | Port: ------------------------------+-------------------------------- On a brand new iMac running MacOSX 10.9 "Mavericks", I clean installed the '''munin''' port. This port is the equivalent of the munin-node package on Debian. Basically it listens on port 4949 from the munin server. Commands from the munin server can be "list" to list all available plugins or "fetch <plugin>" to fetch a particular plugin. One can easily test the plugins by doing telnet 127.0.0.1 4949 then fetch <plugin> == Problem == All munin plugins fail with "#Bad exit": {{{ telnet 127.0.0.1 4949 Trying 127.0.0.1... Connected to localhost. Escape character is # munin node at albert list df df_inode http_loadtime if_en0 if_err_en0 load lpstat netstat ntp_offset processes users fetch load # Bad exit . fetch users # Bad exit . }}} Let's look what is going in the log file'''/opt/local/var/log/munin/munin- node.log''': {{{ 2014/02/12-17:30:06 [27043] 2014/02/12-17:30:06 [27061] Plugin 'users' Can't drop privileges: setruid() not implemented at /opt/local/lib/perl5/site_perl/5.12.4/Munin/Node/OS.pm line 261, <STDIN> line 19.\n.

Just change the user and group to: {{{ user munin group munin }}} Load and unload the munin-node plist: {{{ sudo launchctl unload /Library/LaunchDaemons/org.macports.munin-node.plist sudo launchctl load /Library/LaunchDaemons/org.macports.munin-node.plist }}} ... and the munin plugins now run perfectly. {{{ telnet 127.0.0.1 4949 Trying 127.0.0.1...
