什么进程在UNIX上使用哪些端口？ [英] What processes are using which ports on unix?

问题描述

我需要找出哪些端口连接到Unix计算机（HP Itanium）上的哪些进程。不幸的是， lsof 没有安装，我没有办法安装它。

有没有人知道另一种方法？

解决方案

假设这是HP-UX？ Ptools 的用法 - 你有那些安装？如果是这样，您可以使用pfiles找到应用程序正在使用的端口：

pfiles打印所有打开的文件过程的描述符。
如果文件描述符对应于一个文件，则pfiles打印fstat（2）
和fcntl（2）信息。

如果文件描述符对应一个套接字，则pfiles打印socket
相关信息，例如套接字类型，套接字族和协议族。

在AF_INET和AF_INET6系列套接字的情况下，也打印对等主机的信息
。

for f in $（ps -ex | awk'{print $ 1}'）; do echo $ f; pfiles $ f | grep PORTNUM; done

为端口号切换PORTNUM。 :)可能是孩子pid，但让你足够接近以识别问题的应用程序。

I need to find out what ports are attached to which processes on a Unix machine (HP Itanium). Unfortunately, lsof is not installed and I have no way of installing it.

Does anyone know an alternative method? A fairly lengthy Googling session hasn't turned up anything.

解决方案

Assuming this is HP-UX? What about the Ptools - do you have those installed? If so you can use "pfiles" to find the ports in use by the application:

pfiles prints information about all open file descriptors of a process. If file descriptor corresponds to a file, then pfiles prints the fstat(2) and fcntl(2) information.

If the file descriptor corresponds to a socket, then pfiles prints socket related info, such as the socket type, socket family, and protocol family.

In the case of AF_INET and AF_INET6 family of sockets, information about the peer host is also printed.

for f in $(ps -ex | awk '{print $1}'); do echo $f; pfiles $f | grep PORTNUM; done

switch PORTNUM for the port number. :) may be child pid, but gets you close enough to identify the problem app.
