I'm seting up IPsec between 2 linux boxes.
When I run "setkey -f /etc/.../setkey.conf" I got error "The result of line 23: Protocol not available."
Line 23 of setkey.conf is:
add x.x.x.x y.y.y.y ah 0x200 -A hmac-md5 "1234567890123456";
Is it because hmac-md5 not available? I've tried other choices like hmac-sha1 etc., all have same error.
I googled and didn't see any clear answer.
Thanks for the help.
