Peer-to-Peer Protocols
----------------------
Gnutella=6346|6347|6348
Kazaa=1214
WinMX=6699|7730
DirectConnect=0 Dummy port as this is a pure P2P protocol
eDonkey=4661-4665
-q --create-suspicious-packets 这个参数告诉ntop为“可疑数据包”创建一个导出文件。
有很多很多中情况导致“可疑数据包”的产生,包括:
Detected ICMP fragment
Detected Land Attack against host
Detected overlapping/tiny packet fragment
Detected traffic on a diagnostic port
Host performed ACK/FIN/NULL scan
Host rejected TCP session
HTTP/FTP/SMTP/SSH detected at wrong port
Malformed TCP/UDP/ICMP packet (packet too short)
Packet # %u too long
Received a ICMP protocol Unreachable from host
Sent ICMP Administratively Prohibited packet to host
Smurf packet detected for host
TCP connection with no data exchanged
TCP session reset without completing 3-way handshake
Two MAC addresses found for the same IP address
UDP data to a closed port
Unknown protocol (no HTTP/FTP/SMTP/SSH) detected (on port 80/21/25/22)
Unusual ICMP options
-A --set-admin-password 这个参数用来启动ntop时设置管理口令并退出。当管理人员在安装后需要自动设置ntop的口令时非常有用。
-A and --set-admin-password (不指定值)将会提示用户输入口令。
你可以使用--set-admin-password=yourPassword指定一个口令。“=”是必需的&“不能有空格”。
如果你想把ntop作为守护进程运行而不设定口令,会出现“致命错误”(FATAL ERROR)提示,ntop会
停止!
-B --filter-expression 过滤器可以让用户在任何能想到的条目上对ntop接收到的流量进行限制。在ntop启动时用这个参数指定过滤规则,但是这也可以在运行期间在 Admin|Change Filter页面改变。
基本格式是-B filter,where the quotes are REQUIRED。
