DDoS TCP proxy set-up

[DutchenL]

I'm now doing this: http://forum.ragezone.com/f335/tut-ddos-tcp-proxy-tutorial-959382/

But the last step doesn't work, the proxy won't start. These errors are the ones I get:

(First error is in dutch; says file or map doesn't exist)

What operating system are you using and what version ?

 

[DutchenL]

What operating system are you using and what version ?

Centos 7 (64 bits)

 

[xHosts]

You can try this

systemctl start haproxy

 

[DutchenL]

You can try this

systemctl start haproxy

Nothing happens if I do that?

 

[xHosts]

Did haproxy install correctly when you first installed it ?

 

[DutchenL]

Yes. I did yum install nano

They asked once for Y/N and I said yes (Y). After that it was installed.

 

[Jonteh]

Yes. I did yum install nano

nano is nano, you want yum install haproxy

 

[xHosts]

nano = text editor
haproxy = to proxy your traffic from VPS to your backend server

One can also simply perform ' in-kernel ' packet forwarding without haproxy, and it also works good:

[DutchenL]

Sorry I meant this, Yes i did that they asked once for Y/N and I said Yes.
yum install haproxy

The old tutorial thread is useless, haproxy has been updated.

The configuration is not going to work, this time you have do it yourself. Write a damn configuration script.

Install the latest version of HAProxy (1.6.3)
This config should work

global
   log /dev/log local0
   log /dev/log local1 notice
   chroot /var/lib/haproxy
   stats socket /run/haproxy/admin.sock mode 660 level admin
   stats timeout 30s
   user haproxy
   group haproxy
   daemon

defaults
   log global
   mode tcp
   option dontlognull
   timeout connect 5000
   timeout client 50000
   timeout server 50000

frontend tcp_front
   bind PROTECTED_IP:PROTECTED_PORT
   default_backend tcp_back

backend tcp_back
   balance roundrobin
   server server1 VPS_IP:VPS_PORT check

Then try starting Haproxy

service haproxy start

frontend tcp_front
   bind PROTECTED_IP:PROTECTED_PORT
   default_backend tcp_back

backend tcp_back
   balance roundrobin
   server server1 VPS_IP:VPS_PORT check

Then try starting Haproxy

service haproxy start

Can you explain me how I can install the latest version of haproxy? Install the latest version of HAProxy (1.6.3)

What is the command in putty? Or is it again yum install haproxy?

It would be better if you could learn the basics of linux first, because the way it is, you'll get stuck at every simple issue you face.

Start with a basic linux class, here:



It should help you.

cp /root/haproxy-1.4.24/examples/haproxy.init /etc/init.d/haproxy

chmod 755 /etc/init.d/haproxy

useradd --system haproxy

mkdir -p /etc/haproxy

Edit the config file then save it.

vi /etc/haproxy/haproxy.cfg

global
   log /dev/log local0
   log /dev/log local1 notice
   chroot /var/lib/haproxy

   server server1 VPS_IP:VPS_PORT check

Then run this.

service haproxy start
chkconfig haproxy on

@Hayd3n this is a great hand. But you've just killed his learning curve, because if he had learned linux itself, he wouldn't need that tutorial.
