--- Comment #2 from Jeremy Harris <[email protected]> --- Ah, one more thing the linux kernel did at least at one time - I don't know if it was ever fixed :- They saw fit to disable the entire facility if an initiator ever has to retry a SYN. For quite a long time, before deigning to try again. For all target IPs, not just the one having to retry. That essentially makes it mostly never work if your system ever talks to more than one target. IMHO, totally asinine (yes, I raised a bug...) You can test this by poking the sysctl that disables/enables TFO. -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
