Is there a maximum number of connections that can be proxied

[wlarsong]

Hello I have setup SSH piper to proxy connections between different servers. I have over 2,500 connections and I am finding once I reach 512 connections the SSH piper drops connections.

If I bypass SSH-Piper and all the connections go to one server the server can handle all 2500 without drops. As soon as I add ssh-piper I hit a 512 limit.

Is SSH-piper using a config or line of code to control max connections to one server?

If I use SSH-piper and go to another server with less connections, everything is OK.

user1 *2500 ------------------>ssh-piper ------> Box 1 (Not working Capped at 512)
user2 *5 ----------------------^      |
                                      |-------->Box 2 (  Working all 5 can log in)

did not test so many conns to single piper, but thanks for the input.

there is no cap for sshpiper, did you see any err when accepting connection?
