We are pleased to announce version 2.4 of The GNU Networking Utilities.

GNU Networking Utilities contain traditional networking utilities,
clients and servers, including ftp, telnet, inetd, rsh/rlogin, tftp,
talk, syslogd, ping, traceroute, whois, hostname, dnsdomainname,
ifconfig, and logger.

Happy hacking,

Here are the compressed sources:   (2.6MB)   (1.5MB)

Here are the GPG detached signatures:

Use a mirror for higher download bandwidth:

Here are the SHA1 and SHA256 checksums:

52908bfc6e0bb6bbb54de4414e92c29fd13906d7  inetutils-2.4.tar.gz
dq7gwvCVRyhgDVEJVdaXpOwpMkMY54SEjbYG7jwJ42U  inetutils-2.4.tar.gz
df64dd4ea0e752a839dd51dd8a6a001c9c7d1e96  inetutils-2.4.tar.xz
F4nWsbGlff4qere1M+6fXf2cv1tZuxuzwmEu0I0PaLI  inetutils-2.4.tar.xz

The SHA256 checksum is base64 encoded, instead of the
hexadecimal encoding that most checksum tools default to.

Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify inetutils-2.4.tar.gz.sig

The signature should match the fingerprint of the following key:

  pub   ed25519 2019-03-20 [SC]
        B1D2 BD13 75BE CB78 4CF4  F8C4 D73C F638 C53C 06BE
  uid   Simon Josefsson <>

If that command fails because you don't have the required public key,
or that public key has expired, try the following commands to retrieve
or refresh it, and then rerun the 'gpg --verify' command.

  gpg --locate-external-key

  gpg --recv-keys 51722B08FE4745A2

  wget -q -O- 
 | gpg --import -

As a last resort to find the key, you can try the official GNU

  wget -q
  gpg --keyring gnu-keyring.gpg --verify inetutils-2.4.tar.gz.sig
