After this week's update to nagios-plugins 2.1.1, check_smtp and check_tcp segfault when the port they are meant to be monitoring is closed: nagios@grackle:/usr/local/libexec/nagios>./check_smtp -V check_smtp v (nagios-plugins 2.1.1) nagios@grackle:/usr/local/libexec/nagios>./check_smtp -H localhost Segmentation fault nagios@grackle:/usr/local/libexec/nagios>./check_tcp -V check_tcp v (nagios-plugins 2.1.1) nagios@grackle:/usr/local/libexec/nagios>./check_tcp -H localhost -p 26 Segmentation fault Also when -v is used with no other arguments (I found this by accident, I was aiming for -V): nagios@grackle:/usr/local/libexec/nagios>./check_smtp -v HELOCMD: HELO grackle Segmentation fault nagios@grackle:/usr/local/libexec/nagios>./check_tcp -v Using service TCP Port: 0 flags: 0x2 Segmentation fault Host is FreeBSD 9.3-RELEASE, GENERIC kernel on amd64. Please let me know if I can supply any further information to help resolve this. Thanks!
Please, report that to the nagios-plugins people, it's not a FreeBSD specific problem.
