Hi All, We would need to choose a fixed port for communication between our server and an external app. From time to time to we run into issues as Linux assigns this port to another app during startup. ip_local_reserved_ports ( https://patchwork.kernel.org/patch/76954/ ) would have solved this cleanly but the kernel we are using does not support this functionality. I see some people recommending using unassigned/reserved ports at http://stackoverflow.com/questions/133879/how-should-one-go-about-choosing-a-default-tcp-ip-port-for-a-new-service and this seems risky. Registering a port with IANA is an option but the process seems to be lengthy. This application does not need to be portable to other operating systems so I am wondering if we could choose a port outside the Linux ephemeral range as specified in ip_local_port_range max value. This max value on Linux is 61000 so can a port number greater than 61000 be used for such needs? The Linux kernel versions I need to support are 2.6.14 and 2.6.27.
