# snoop
2. 监听所有以主机A为源和目的的包并将其显示出来. ( A为主机名, 下同)
- 2 -
# snoop A
3. 监听所有A和B之间的包并将其保存到文件file.
# snoop -o file A B
4. 显示文件file 中指定的包(99-108)
# snoop - i file -p 99,108
99 0.0027 boutique -> sunroof NFS C GETATTR FH=8E6C
100 0.0046 sunroof -> boutique NFS R GETATTR OK
101 0.0080 boutique -> sunroof NFS C RENAME FH=8E6C MTra00192
to .nfs08
102 0.0102 marmot -> viper NFS C LOOKUP FH=561E screen.r.13.i386
103 0.0072 viper -> marmot NFS R LOOKUP No such file or Directory
104 0.0085 bugbomb -> sunroof RLOGIN C PORT=1023 h
105 0.0005 kandinsky -> sparky RSTAT C Get Statistics
106 0.0004 beeblebrox -> sunroof NFS C GETATTR FH=0307
107 0.0021 sparky -> kandinsky RSTAT R
108 0.0073 Office -> jeremiah NFS C READ FH=2584 at 40960 for 8192
5. 详细查看文件file 中第101 个包:
# snoop - i file - v -p101
ETHER: ----- Ether Header -----
ETHER:
ETHER: Packet 101 arrived at 16:09:53.59
ETHER: Packet size = 210 bytes
ETHER: Destination = 8:0:20:1:3d:94, Sun
ETHER: Source = 8:0:69:1:5f:e, Silicon Graphics
ETHER: Ethertype = 0800 (IP)
ETHER:
IP: ----- IP Header -----
IP:
IP: Version = 4, header length = 20 bytes
IP: Type of service = 00
IP: ..0. .... = routine
IP: ...0 .... = normal delay
IP: .... 0... = normal throughput
IP: .... .0.. = normal reliability
IP: Total length = 196 bytes
IP: Identification 19846
IP: Flags = 0X
IP: .0.. .... = may fragment
IP: ..0. .... = more fragments
?

?
6. 查看主机A和主机B之间的NFS 包(命令中的and 和or 为相应的逻辑运
算)
# snoop - i file rpc nfs and A and B
1 0.0000 A -> B NFS C GETATTR FH=8E6C
2 0.0046 B -> A NFS R GETATTR OK
3 0.0080 A -> B NFS C RENAME FH=8E6C MTra00192 to .nfs08
7. 将这些符合条件的包保存到另一文件file2 中:
# snoop - i file -o file2 rpc nfs A B
8. 监听主机A和主机B间所有TCP 80 端口或UDP80端口的包
# snoop A and B and (tcp or udp) and port 80
9. 监听所有的广播包
# snoop broadcast
Using device /dev/hme (promiscuous mode)
10.10.10.50 -> BROADCAST UDP D=177 S=2541 LEN=35
10.10.10.50 -> BROADCAST UDP D=177 S=2541 LEN=35
10.10.10.50 -> BROADCAST UDP D=177 S=2541 LEN=35
10. 监听所有的多播包, 并显示详细内容.
#snoop -v multicast
ETHER: ----- Ether Header -----
ETHER:
ETHER: Packet 1 arrived at 12:33:2.16
ETHER: Packet size = 69 bytes
ETHER: Destination = ff:ff:ff:ff:ff:ff, (broadcast)
ETHER: Source = 0:4:76:46:8f:50,
ETHER: Ethertype = 0800 (IP)
ETHER:
IP: ----- IP Header -----
IP:
IP: Version = 4
IP: Header length = 20 bytes
IP: Type of service = 0x00
IP: xxx. .... = 0 (precedence)
IP: ...0 .... = normal delay
- 4 -
IP: .... 0... = normal throughput
IP: .... .0.. = normal reliability
IP: Total length = 55 bytes
IP: Identification = 14658
IP: Flags = 0x0
IP: .0.. .... = may fragment
IP: ..0. .... = last fragment
IP: Fragment offset = 0 bytes
IP: Time to live = 128 seconds/hops
IP: Protocol = 17 (UDP)
IP: Header checksum = ed38
IP: Source address = 10.10.10.50, 10.10.10.50
IP: Destination address = 255.255.255.255, BROADCAST
IP: No options
IP:
UDP: ----- UDP Header -----
UDP:
UDP: Source port = 2541
UDP: Destination port = 177
UDP: Length = 35
UDP: Checksum = 8E35
UDP:
ETHER: ----- Ether Header -----
ETHER:
ETHER: Packet 2 arrived at 12:33:12.16
ETHER: Packet size = 69 bytes
ETHER: Destination = ff:ff:ff:ff:ff:ff, (broadcast)
ETHER: Source = 0:4:76:46:8f:50,
ETHER: Ethertype = 0800 (IP)
ETHER:
IP: ----- IP Header -----
IP:
IP: Version = 4
IP: Header length = 20 bytes
IP: Type of service = 0x00
IP: xxx. .... = 0 (precedence)
