Before I set about recompiling I thought I'd compare the F26 plugins with the versions from F25. The three plugins I'm seeing problems with are: check_nrpe check_ping check_load When I compare versions both F25 and F26 are using the same versions of each of the plugins.

CODE: SELECT ALL chmod ug+s check_ping Setting the super user bit has not resolved this. -rwsr-sr-x 1 root root 66272 Apr 21 00:13 check_ping ./check_ping 127.0.0.1 -w 3000.0,80% -c 5000.0,100% -p 5 C...
