LINX is an inter process communication protocol developed by Enea used for local and remote communications in distributed systems.


LINX is based on the IPC method - called LINK - used in Enea's OSE operating system. A Linux kernel module implementing the protocol is released as open source.

Protocol dependencies

  • Ethernet: So far LINX can only use Ethernet as its transport protocol besides shared memory. The ethertype 0x9999 used right now is not assigned by IEEE.

Example traffic



The LINX dissector is fully functional but could be improved for sure:

  • Reassembling of fragmented packages
  • Improve RLNH handling
  • Improve info column
