Changelog

All notable changes to this project will be documented in this file.

v2.1.1 - 2021-03-21

  • Rollback changes made to the traceroute function due to a bug.

v2.1.0 - 2021-03-20

  • Add a family parameter to the resolve function to define the address family.
  • Improve the reliability of the results of the traceroute function.

This version is the last of the 2.x branch. See you soon for the release of icmplib 3.0!

v2.0.2 - 2021-02-07

  • Rename the default branch from master to main.
  • Fix a bug preventing the traceroute function to work with IPv6 addresses (part 2).
  • Add more details about the privileged parameter in the README file (part 2).

v2.0.1 - 2020-12-12

  • Handle EACCES errors at sockets level.
  • Fix a bug preventing the traceroute function to work with IPv6 addresses.
  • Add some details about the privileged parameter in the README file.

v2.0.0 - 2020-11-15

icmplib 2.0 is here! :tada:

Here is an overview of the improvements: - All the foundations of the library have been completely reworked to make it even faster and simplify future developments. - You can now use the library without root privileges. Remember to disable the privileged parameter on functions and sockets. - The multiping function has been rewritten to use only one thread instead of as many threads as hosts to reach. This function will be up to 10 times faster and up to 2 times more memory efficient. - You can set a source IP address for sending your ICMP packets. - The traceroute function now has a first_hop parameter to specify the initial time to live value. - Two new exceptions have been added: NameLookupError and SocketAddressError - Compatibility with Linux, macOS and Windows has been improved. - Docstrings, examples and documentation have been updated.

And more! - The receive method of sockets can receive all incoming packets. - The new BufferedSocket class (experimental) can read and classify incoming ICMP packets into a buffer, in real time. Useful if you want to send several ICMP packets consecutively without waiting for a response between each sending. - Sockets throw new exceptions during instantiation, sending and receiving. - The resolve function now raises a NameLookupError if the requested name does not exist or cannot be resolved. - Compatibility with existing programs is maintained.
