红帽全球峰会46.12. 追踪 IPv4 和 IPv6 侦听尝试
solisten 工具追踪所有 IPv4 和 IPv6 侦听尝试。它跟踪尝试，包括最终失败的或者不接受连接的侦听程序。当程序希望侦听 TCP 连接时，工具会跟踪内核调用的函数。
流程
输入以下命令启动显示所有监听 TCP 尝试的追踪过程：
# /usr/share/bcc/tools/solisten PID COMM PROTO BACKLOG PORT ADDR 3643 nc TCPv4 1 4242 0.0.0.0 3659 nc TCPv6 1 4242 2001:db8:1::1 4221 redis-server TCPv6 128 6379 :: 4221 redis-server TCPv4 128 6379 0.0.0.0 ....- 按 Ctrl+C 停止追踪过程。
