linux - 如何测试短暂端口的耗尽(How to test ephemeral ports exhaustion)

Question

is there any way (tool) in Linux that can be used to reserve all ephemeral ports?

(Linux中有什么方法（工具）可用于保留所有临时端口？)

the reason for this is that I am testing remediation when all outbound ports are in use.

(原因是当所有出站端口都在使用时，我正在测试补救措施。)

I've tested apache "ab" but it does not seem there is a way to allocate all outbound ports on the system.

(我已经测试过apache“ ab”，但似乎没有办法在系统上分配所有出站端口。)

I am viewing the available ports using the below:

(我正在使用以下方法查看可用的端口：)

first_port=$(cut --fields 1 /proc/sys/net/ipv4/ip_local_port_range)
last_port=$(cut --fields 2 /proc/sys/net/ipv4/ip_local_port_range)
ss --numeric --tcp state connected "( sport >= :$first_port and sport <= :$last_port )"
