Tcpcrypt incompatible with ECN

Open jech opened this issue 14 years ago • 2 comments

Run

sudo sysctl net.ipv4.tcp_ecn=1

and tcpcrypt is no longer negotiated.

This is on x86, under Debian's Linux 2.6.37-1, running git 91cce740.

Thanks for reporting this. I've added a note to the Linux installation instructionsm about this, and I'll leave this issue open until it's resolved.

Without ECN, tcpcrypt seems limited to Linux servers that don't expect to face any incast issues.
