You won’t find the patches because they are not needed for that Kernel version. It is already built in!

I’ve installated HAproxy on Debian with kernel Linux 2.6.32+.
When HAproxy starts, I’ve the following error:
Starting haproxy: haproxy

[ALERT] 024/152707 (1802) : parsing [/etc/haproxy/hapr xy.cfg:54] : ‘usesrc’ not allowed here because support for TPROXY was not compiled in.

May you help me? Have any suggestions?

Please have a look at our new Blog post at http://blog.loadbalancer.org/setting-up-haproxy-with-transparent-mode-on-centos-6-x/ which should help.

If you have a High-availability pair of HA-Proxy units this would be the internal floating IP, if you just have a single unit then you would probably just have one IP address. The VIP or bind address would usualy be on the external network (so you definately would not use that one).

I’ve got couple of questions:

1. It’s 100% mandatory to change default gateway of real servers to point to 1 of the haproxy IP addresses?

2. If yes, which one? The VIP one?

Regards
