Linux: check which program and process id (pid) listening on a particular port

For example, I want to check which program listening to port 8083, I can use the below command:

Netstat command

[root@myservertmp]#  netstat -taupen | grep 8083
Proto Recv-Q Send-Q Local Address  Foreign Address  State   User Inode PID/Program name
tcp        0      0 0.0.0.0:8083   0.0.0.0:*        LISTEN  500  54617 9894/java      
[root@myserver tmp]# ls -l /proc/9894/exe
lrwxrwxrwx. 1 sas sas 0 Jan 28 21:11 /proc/9894/exe -> /opt/myprog/thirdparty/jdk/jdk1.6.0_30/bin/java

fuser command

# fuser 8083/tcp
