2007-01-28Don't try to print `optarg' (which will be a NULL pointer) if an unknownHolger Weiss1-1/+1
command line option was used, as this leads to a segfault on some systems. The unknown option will be printed by getopt(3) anyway. So, simply call print_usage() and exit UNKNOWN via the new usage5() instead. git-svn-id: https://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk@1590 f882894a-f735-0410-b71e-b25c423dba1c
2007-01-20compilation fixes for check_ntp.c:M. Sean Finney1-3/+3
- check_ntp.c:290: warning: overflow in implicit constant conversion fixed with an explicit cast to int8_t. - check_ntp.c:544: warning: pointer of type ‘void *’ used in arithmetic fixed by casting to ptrdiff_t before arithmetic and (void*) afterwards - in TVtoNTP64, cast arithmetic result passed to R32 as uint64_t. git-svn-id: https://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk@1571 f882894a-f735-0410-b71e-b25c423dba1c

2006-05-01- check_ntp:M. Sean Finney1-76/+144
- now roughly feature-complete. - various bugfixes, esp. offset calculation. - enhanced the asynchronous offset polling to set requests that haven't recieved a response in >= 1 second to stale and retransmit them, which results in much better performance on unreliable networks. - we only spend timeout/2 seconds polling offsets, and if we don't get everything by that point we work with what we have and set status to warning/critical depending on how much data we have. - set the same defaults as the perl script. - commit changes to configure.in to support automatic building of check_apt (if apt-get is installed and regex libraries available) and check_ntp (unconditionally), now defaulting to check_ntp.c instead of the perl script. if this is an issue we can back out the commit of course. an eye should be kept on check_ntp building and running correctly in different environments, esp. 64-bit and big-endian platforms, and those with more "esoteric" API's (do any of the platforms not have poll()?). - similar changes to Makefile.am's. - common.h: add statement to include sys/poll.h - runcmd.c: exit STATE_UNKNOWN if execve() fails. git-svn-id: https://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk@1386 f882894a-f735-0410-b71e-b25c423dba1c
2006-04-12the offset_requests are now parallelized. still stuff needs to beM. Sean Finney1-62/+105
done (conveniently marked with XXX), but on well behaving networks the plugin should behave more or less identical to check_ntp.pl now. git-svn-id: https://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk@1373 f882894a-f735-0410-b71e-b25c423dba1c
2006-04-12added a currently unused but "good for reference" version of offset_requestM. Sean Finney1-0/+76
which attempts to behave more like ntpdate, but this doesn't yet and the code isn't actually used yet. git-svn-id: https://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk@1372 f882894a-f735-0410-b71e-b25c423dba1c
2006-04-11another big code-commit to check_ntp. jitter calculations now work, andM. Sean Finney1-22/+247
the program is becoming much closer on the packet-for-packet level to how check_ntp.pl behaves. i'll send an email in the morning :) git-svn-id: https://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk@1371 f882894a-f735-0410-b71e-b25c423dba1c
2006-03-20- shuffling some code around to keep things tidy.M. Sean Finney1-19/+32
- now average the result of 4 queries just as ntpdate does - put things in place for jitter calculation git-svn-id: https://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk@1332 f882894a-f735-0410-b71e-b25c423dba1c

2006-03-18initial version of the pure-c check_ntp implementation. jitter not yetM. Sean Finney1-0/+355
implemented, and a couple other misc things to do, so i haven't yet patched Makefile.am git-svn-id: https://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk@1330 f882894a-f735-0410-b71e-b25c423dba1c
