This commit does not add tests that verify the exact limit,
because pinging 100000 localhost addresses takes over 15
minutes on my PC. I have tested this fix manually.
As described in GH issue #299, the MAX_GENERATE+1 limit is only
applied when using an address range, not when using CIDR. This
commit changes this to always honor the generator limit.
* refactor target address generation to use the same new function
for both range and CIDR notation
* check the limit for addresses to generate in the new function
* document the generator limit in "fping --help" output
* document the generator limit in the fping man page
* test that the address generation limit applies when using CIDR
notation
With -Q SECS, fping emits information for the just finished
interval. This is good for long-running fping processes where
one would like to get an update on recent results, ignoring
missing responses from older intervals. This seems appropriate
for use with other software like netdata or smokeping.
But for short(er)-running fping processes, e.g., during a change
window, it may be more interesting to get a status update since
the beginning of the change window, i.e., the start of fping.
Adding a comma followed by the keyword "cumulative" to -Q SECS
(i.e., -Q SECS,cumulative) changes the interim reports to output
the current per system overall statistics, unless -N is used, too.
The new syntax is documented in fping.pod and added to fping -h
output.
Four tests are added:
1. Characters after SECS are ignored as before.
2. Unknown keywords are ignored as before.
2. Adding ",cumulative" changes -Q output.
3. Adding ",cumulative" also affects the additional -o output.
This addresses issue #243.
With the options -x and -X, fping does not require all hosts to
be reachable for an exit status of 0.
This addresses a comment in issue #99 suggesting such a man page
update.
The `-Q, --squiet=SECS` option does not replace the summary
statistics of `-q, --quiets`, but adds interval summary
statistics every SECS seconds to the output.
* Adjust `fping.pod` entries for `-d, --rdns` and `-n, --name`:
* The code performs reverse DNS lookups on the given targets,
not on source addresses from ICMP Echo Responses or ICMP
error messages. Adjust the `-d` description to reflect this.
* The sentence describing `-n` seems incomplete, so provide a
completion in similar spirit to `-d`.
* Add `-d, --rdns` to `-h, --help` output since `-d` and `-n` are
no longer equivalent.
The option --src is an alias for the uppercase -S.
Stumbled upon this in the man page.
When running "fping -h", the option is printed correctly:
$ -s, --stats print final stats
