一、IP過濾：包括來源IP或者目標(biāo)IP等于某個(gè)IP
比如：ip.src addr==192.168.0.208??or ip.src addr eq 192.168.0.208 顯示來源IP
? ?? ???ip.dst addr==192.168.0.208??or ip.dst addr eq 192.168.0.208 顯示目標(biāo)IP

二、端口過濾：
比如：tcp.port eq 80 // 不管端口是來源的還是目標(biāo)的都顯示
? ?? ???tcp.port == 80
? ?? ???tcp.port eq 2722
? ?? ???tcp.port eq 80 or udp.port eq 80
? ?? ???tcp.dstport == 80 // 只顯tcp協(xié)議的目標(biāo)端口80
? ?? ???tcp.srcport == 80 // 只顯tcp協(xié)議的來源端口80

過濾端口范圍
tcp.port >= 1 and tcp.port <= 80

三、協(xié)議過濾：tcp
udp
arp
icmp
http
smtp
ftp
dns
msnms
ip
ssl
等等
排除ssl包，如!ssl 或者??not ssl

四、包長(zhǎng)度過濾：
比如：
udp.length == 26 這個(gè)長(zhǎng)度是指udp本身固定長(zhǎng)度8加上udp下面那塊數(shù)據(jù)包之和
tcp.len >= 7??指的是ip數(shù)據(jù)包(tcp下面那塊數(shù)據(jù)),不包括tcp本身
ip.len == 94 除了以太網(wǎng)頭固定長(zhǎng)度14,其它都算是ip.len,即從ip本身到最后
frame.len == 119 整個(gè)數(shù)據(jù)包長(zhǎng)度,從eth開始到最后

五、http模式過濾：
例子:
http.request.method == "GET"
http.request.method == "POST"
http.request.uri == "/img/logo-edu.gif"
http contains "GET"
http contains "HTTP/1."

// GET包
http.request.method == "GET" && http contains "Host: "
http.request.method == "GET" && http contains "User-Agent: "
// POST包
http.request.method == "POST" && http contains "Host: "
http.request.method == "POST" && http contains "User-Agent: "
// 響應(yīng)包
http contains "HTTP/1.1 200 OK" && http contains "Content-Type: "
http contains "HTTP/1.0 200 OK" && http contains "Content-Type: "
一定包含如下
Content-Type:

六、連接符 and / or

七、表達(dá)式：!(arp.src==192.168.1.1) and !(arp.dst.proto_ipv4==192.168.1.243)
