hello,
perhaps it's something that i'm doing wrong here, or a difference
in the way that relayd works compared to hoststated. but here
goes.. i'm attempting to get relayd configured to replace my existing
hoststated setup, doing layer 7 load balancing of web servers.
what's happening is with every http check done, relayd returns a
connect failure. in doing a tcpdump i see the session is
brought up by relayd to the destination servers, the server responds
with a syn/ack, and then a rst is sent by the system running relayd.
...
i have a similar hoststated configuration running on the very same
system, load balancing the very same hosts. it operates as expected,
with the hosts being seen as up and available.
i have attached relayd debug log output, my relayd configuration
file, as well as hoststated debug and the hoststated config.
could someone perhaps shed some light on what i'm doing wrong, if
anything? perhaps a bug in the http check/tcp check code?
if i could be cc'd on any replies, i'd appreciate it. i'm not
currently subscribed to [EMAIL PROTECTED]
cheers,
-ben
