Is there a way to overcome the port limit on a linux system? We have a server running that accepts incoming connection and it uses very little memory and cpu. It’s rather silly that we have to build a cluster of small linux boxes just to overcome a software limit (number of points of around 60k). Any ideas?
There is no limit of 60k tcp or udp sockets, you just think there is. The actual limit is much higher. There are 64k ports, but the same port may be used for more than one connection, as only the pair of addresses/ports needs to be unique.
Having said that, if you have 60k distinct clients concurrently connected, you may a have high availability requirement which means you’ll need to have several machines anyway.
