| fping 4.0 (2017-04-23) | ||
| ====================== | ||
|
|
||
| ## Incompatible Changes | ||
|
|
||
| ##### fping and fping6 unification | ||
|
|
||
| fping and fping6 are now unified into one binary. It means that, for example, | ||
| doing 'fping google.com' is going to ping the IPv6 IP of google.com on | ||
| IPv6-enabled hosts. | ||
|
|
||
| If you need exact compatibility with old versions, you can configure and | ||
| install fping twice: once for ipv4, and once for ipv6: | ||
|
|
||
| ./configure --disable-ipv6; make clean install | ||
| ./configure --disable-ipv4 --program-suffix=6; make clean install | ||
|
|
||
| ##### Option -n, not the same as -d anymore | ||
|
|
||
| Option -n / --name is now doing a reverse-DNS lookups on host addresses, | ||
| only if they are given as IP address, but not for hostnames. For example, | ||
| if you write 'fping -n google.com', fping would previously do a | ||
| forward-DNS lookup on google.com, and then a reverse-DNS lookup on the | ||
| resolved IP address. Now, it is just going to keep the name 'google.com'. | ||
| That same behavior can be achieved with the option -d / --rdns (which was | ||
| previously an alias for -n). | ||
|
|
||
| fping<4.0 fping>=4.0 | ||
| fping -n NAME NAME->IP->IPNAME NAME | ||
| fping -d NAME NAME->IP->IPNAME NAME->IP->IPNAME | ||
|
|
||
| ##### Discarding of late packets | ||
|
|
||
| fping will now discard replies, if they arrive after the defined timeout | ||
| for reply packets, specified with -t. This change is relevant only for the | ||
| count and loop modes, where the measured times should be now more | ||
| consistent (see github issue #32 for details). | ||
|
|
||
| To prevent loosing reply packets because of this change, the default | ||
| timeout in count and loop modes is now automatically adjusted to the | ||
| period interval (up to 2000 ms), but it can be overriden with the -t | ||
| option. The default timeout for non-loop/count modes remains 500 ms. | ||
|
|
||
| ##### No restrictions by default | ||
|
|
||
| fping will not enforce -i >= 1 and -p >= 10 anymore, except if you | ||
| './configure --enable-safe-limits'. | ||
|
|
||
| The reasoning to removing the restrictions by default, is that users can | ||
| clog the network with other tools anyway, and these restrictions are | ||
| sometimes getting in the way (for example if you try to ping a lot of | ||
| hosts). | ||
|
|
||
| ##### Default interval (-i) changed from 25ms to 10ms | ||
|
|
||
| The default minimum interval between ping probes has been changed from | ||
| 25ms to 10ms. The reason is that 25ms is very high, considering today's | ||
| fast networks: it generates at most 31 kbps of traffic (for IPv4 and | ||
| default payload size). | ||
|
|
||
| ## New features | ||
|
|
||
| - Unified 'fping' and 'fping6' into one binary (#80) | ||
| - Long option names for all options | ||
| - IPv6 enabled by default | ||
| - New option -4 to force IPv4 | ||
| - New option -6 to force IPv6 | ||
| - Keep original name if a hostname is given with -n/--name | ||
| - Option -d/--rdns now always does a rdns-lookup, even for names, as '-n' was doing until now | ||
| - Enforce -t timeout on reply packets, by discarding late packets (#32) | ||
| - Auto-adjust timeout for -c/-C/-l mode to value of -p | ||
|
|
||
| ## Bugfixes and other changes | ||
|
|
||
| - -i/-p restrictions disabled by default (enable with --enable-safe-limits) | ||
| - Default interval -i changed from 25ms to 10ms | ||
| - Fix compatibility issue with GNU Hurd | ||
| - A C99 compiler is now required | ||
| - Option parsing with optparse (https://github.com/skeeto/optparse). Thanks Christopher Wellons! | ||
| - New changelog file format |
