如何察看端口是什么进程打开的？

babysgaler

本机Ip是192.168.12.17

-bash-3.00$ netstat -an | grep .5080
192.168.12.17.48375  192.168.12.65.5080   66270      0 49350      0 TIME_WAIT
192.168.12.17.48444  192.168.12.65.5080   66270      0 49350    497 ESTABLISHED
192.168.12.17.48445  192.168.12.68.5080   33135      0 49350      0 ESTABLISHED

如何察看是什么进程打开的端口和远程主机192.168.12.65的5080口连接？

谢谢帮忙

使用 #pfiles /proc/*
pfiles读取/proc下的进程ID作为参数

todaypuzzleme

根据你系统的版本从sunfreeware(www.sunfreeware.com)下个lsof安装包，安装后使用
/usr/local/bin/lsof -i | grep 端口号
可插到进程，从进程
ps -ef|grep 进程号
就知道了

1.  rpcinfo -p ---> program number
2.  cat /etc/rpc   ----> from program number find program name.

刚找到个更简单的办法
#pfiles * > /tmp/pf.out
#vi pf.out
查找端口关键字，可看到关联的文件信息，包括inode num
再find文件
#find / -inum inodenum 查找文件

使用lsof是一个比较通用的方法

谢谢各位解答
2#因为我们系统比较重要，不让自己装软件，所以不能下载lsof
3#可是如果端口不是rpc进程打开的，在/etc/rpc里面不是找不到吗？
4#我执行pfile *的时候报下面错误，这是怎么回事呢？
bash-3.00# pfiles *
