Linux/window下怎樣查看某個連接埠被哪個程式/進程佔用

Windows:
C:/Users/ewanbao>netstat -aon|findstr "123"
TCP 127.0.0.1:55123 0.0.0.0:0 LISTENING 5092
TCP 127.0.0.1:55123 127.0.0.1:55124 ESTABLISHED 5092
TCP 127.0.0.1:55124 127.0.0.1:55123 ESTABLISHED 5092
UDP 0.0.0.0:123 *:* 1416
UDP [::]:123 *:* 1416
[注]:執行netstat -aon|findstr "123"以後，就可以看到5092進程中TCP開啟123連接埠，1416進程開啟UDP123連接埠

C:/Users/ewanbao>tasklist|findstr "1416"
svchost.exe 1416 Services 0 13,540 K
[注]：執行tasklist|findstr "1416"後就可以看到是svchost.exe在UDP開啟123連接埠
Linux:
cba001:~ # lsof -i:5300
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
named 26751 root 20u IPv4 64750499 TCP localhost:hacl-hb (LISTEN)
named 26751 root 21u IPv4 64750501 TCP cba001.eapac:hacl-hb (LISTEN)
named 26751 root 22u IPv4 64750503 TCP 192.168.0.10:hacl-hb (LISTEN)
named 26751 root 512u IPv4 64750498 UDP localhost:hacl-hb
named 26751 root 513u IPv4 64750500 UDP cba001.eapac:hacl-hb
named 26751 root 514u IPv4 64750502 UDP 192.168.0.10:hacl-hb
[注]:執行lsof -i:5300以後就可以看到26751進程在TCP和UDP上都開啟了5300連接埠.
cba001:~ # ps -ef|grep 26751
root 10118 26915 0 12:59 pts/8 00:00:00 grep 26751
root 26751 1 0 Jul06 ? 00:02:06 /opt/ipworks/IPWdns/usr/bin/named
[注]:執行ps -ef|grep 26751以後就可以看到是named進程開啟了5300連接埠

查看進程ID：
lsof -w -n -i tcp:8080
fuser -n tcp 8080netstat -anp|grep :8080[[:blank:]]
殺掉佔用連接埠的進程PID：
kill -9 pidnumber
