Because these all are * free * socks5 proxy servers found on the internet, the stability cann't be ensured. Some of them can be used to let my browser directly access the internet, some may not; or if do the test in different time, the one cann't becomes good, and vice versa. Based on the above fact, I want to use all of them in one group of the backend of haproxy to get the redundancy and the loadbalance capability. The only issue for my case it that I want let haproxy to determine the correspoing server are up or down at the specific port and then direct me the up ones at the testing time done by haproxy.

Re: Health check for backend constituted with multiple socks proxies.
I mean what happens if you point your browser directly to one of the Ip address? Cause, what you're doing with your HAProxy configuration currently, is only forwarding the TCP connection from a browser client to a socks5 server. If your browser client don't know how to speak to the socks5 server, HAProxy won't do it on behalf of it. So please confirm first the browser can use any of the listed IP without using HAProxy. Then we'll dig into your issue...

Health check for backend constituted with multiple socks proxies.
Hi all, My haproxy.cfg is as follows: - global maxconn 4096 daemon nbproc 3 defaults mode tcp timeout connect 5000ms timeout client 5ms timeout server 5ms frontend socks5 bind0.0.0.0: default_backend socks5-balance backend socks5-balance balance roundrobin server socks5-1 104.220.35.112:48178 check server socks5-2 104.236.196.208:1234 check server socks5-3 113.61.111.196:60088 check server socks5-4 114.94.131.120:8118 check server socks5-5 115.119.233.36:2235 check server socks5-6 115.29.49.52: check server socks5-7 117.247.65.204:1080 check server socks5-8 118.26.201.224:1080 check server socks5-9 118.26.228.8:1080 check ... server socks5-3194.23.80.193:60088 check server socks5-3295.163.65.88:49389 check - I found that the the health-check results given by haproxy are not consistent with the real statues/availabilities of these servers listed in the backend section. For example, when I use the -db mode to see the message on stdout, I can found that even haproxy reported there are serveral backend servers are available, I still cann't use 127.0.0.1: as proxy to access websites/ urls. Any hints on how to let haproxy give a more precise/reliable/correctness health-check for this case? Thanks in advance. Regards -- .: Hongyi Zhao [ hongyi.zhao AT gmail.com ] Free as in Freedom :.
