I'm using a Debian 9 image on a virtual machine. The ping command is not installed. When I run:

sudo apt-get install ping

It asks me:

Package ping is a virtual package provided by:
  iputils-ping 3:20161105-1
  inetutils-ping 2:1.9.4-2+b1
You should explicitly select one to install.

Why is there two ping utilities? What are the differences between them? Is there some guidelines to choose one version over the other? What are the implications of this choice? Will all scripts and programs be compatible with both versions?

iputils’s ping supports quite a few more features than inetutilsping, e.g. IPv6 (which inetutils implements in a separate binary, ping6), broadcast pings, quality of service bits... The linked manpages provide details.

iputilsping supports all the options available on inetutilsping, so scripts written for the latter will work fine with the former. The reverse is not true: scripts using iputils-specific options won’t work with inetutils.

As far as why both exist, inetutils is the GNU networking utilities, targeting a variety of operating systems and providing lots of different networking tools; iputils is Linux-specific and includes fewer utilities. So typically you’d combine both to obtain complete coverage and support for Linux-specific features, on Linux, and only use inetutils on non-Linux systems.

  • Thank you for your answer. You say that typically you combine both to obtain complete coverage but as both implement the virtual package ping, If I install one the other is removed. How do you combine them? – Ortomala Lokni Oct 25 '17 at 14:09
  • @Ortomala I meant that you combine both sets of utilities: for example, ftp from inetutils, ping from iputils, etc. (That part of my answer wasn’t focused on ping specifically.) – Stephen Kitt Oct 25 '17 at 14:18

inetutils-ping is the portable GNU implementation, which is used on non-Linux Debian systems (such as Debian GNU/kFreeBSD).

iputils-ping is Linux only, but does have more features. If you are using Linux, you probably want iputils version of ping.

    I learned from @StephenKitt's answer that iputils-ping supports ipv6 with same binary (ipv6 is a symlink), while inetutils-ping provides a separate ping6 binary. Both support ipv6, but the symbolic links aren't visible from packages.debian.org file listings. – sebasth Oct 25 '17 at 13:02
  • i have tested the ping from both packages . ping6 seems to work only when installing the inetutils-ping thx again – GAD3R Oct 25 '17 at 13:08
  • @GAD3R What do you need the ping6 command for, if ping from iputils-ping supports both protocols? You can force it to use only either protocol with the -4 and -6 switches, should the need arise. – Johan Myréen Oct 25 '17 at 13:35

    @GAD3R that’s weird, iputils-ping installs a ping6 symlink, so you should be able to ping6 :: without installing inetutils-ping at all (and I can, on the systems I’ve checked this on). – Stephen Kitt Oct 25 '17 at 14:20

You can install one of them , the tow package provide the ping binary , the inetutils-ping will provide an additional tool ping6
