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!

fping 3 README
|
||||
--------------
|
||||
fping is a program to send ICMP echo probes to network hosts, similar to ping,
|
||||
but much better performing when pinging multiple hosts. fping has a long long
|
||||
story: Roland Schemers did publish a first version of it in 1992 and it has
|
||||
established itself since then as a standard tool.

||||
|
||||
|
||||
Installation
|
||||
------------
|
||||
If you want to install fping from source, proceed as follows:
|
||||
|
||||
0. Run ./autogen.sh
|
||||
(only if you got the source from github)
|
||||
|
||||
1. Run ./configure with the correct arguments
|
||||
(see: ./configure --help)
|
||||
|
||||
2. Run make; make install
|
||||
|
||||
3. Make fping either setuid, or, if under Linux:
|
||||
|
||||
sudo setcap cap_net_raw+ep fping
|
||||
|
||||
4. Have a look at the fping(8) manual for usage help
|
||||
(fping -h will also give a minimal help output)
|
||||
|
||||
|
||||
IPv6 support
|
||||
------------
|
||||
You can can compile fping with support for IPv6 addresses. A separate binary
|
||||
is used for that, called fping6. To build it, use ./configure --enable-ipv6
|
||||
(possibly combined with --enable-ipv4 to also build fping for IPv4). E.g.:
|
||||
|
||||
# ./configure --prefix=/usr/local --enable-ipv4 --enable-ipv6
|
||||
# make
|
||||
# make install
|
||||
# sudo setcap cap_net_raw+ep /usr/local/bin/fping*

* Version 4.0

|
||||
|
||||
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,
|

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
|
