Governor Dhankar criticises Mamata govt to serve ‘political masters’: Derek O’Brien
NEW DELHI: Trinamool Congress (TMC) MP Derek O’Brien on Monday slammed West Bengal Governor Jagdeep Dhankhar for allegedly demeaning and criticising the state without any basis. “Normally ignored you, but you have crossed the line. Enough. You are nothing but His Master’s Voice! You are a disgrace to the office you hold. Without basis, u criticize and demean Bengal to serve your political masters. U do this while enjoying Bengal’s hospitality. Shame on you,” O’Brien tweeted.

The TMC leader was responding to tweets by the governor where the latter was attacking chief minister Mamata Banerjee. “Alarming reports that De facto boss WB Police Surajit Kar Purakayastha #SSA Mamata Banerjee vigorously engaged in translating politically motivated police actions. Concerned at Field police work of DGP- postings and transfer, investigation usurped by De facto boss Purakayastha,” Dhankhar tweeted. “Such capitulation DGP WB Police and usurpation #SSA Mamata Banerjee sound the death knell of democracy. Such gross violation of the Police Act and constitutional provisions proves the political stance of police and administration that is by law required to be “politically neutrality,” he said in another tweet.

— Governor West Bengal Jagdeep Dhankhar (@jdhankhar1) 1609156654000
The governor said that decoupling of police from political work is a must for the survival of democracy. “Political Neutrality is the quintessence of administration as per law. Its disregard by public servants by engaging as political workers cannot be countenanced. Such misconduct entails serious consequences,” he said.

Prez rule in WB not possible after case heard by SC: Nitish
Amid a national brouhaha over the developments in Kolkata on Sunday evening involving CBI and West Bengal CM Mamata Banerjee, Bihar CM and NDA ally Nitish Kumar played it down saying election is round the corner and many things will happen in next one month.
However when asked about imposition of President rule in West Bengal, Nitish said, “It is not possible since the matter is under hearing of the Supreme court.”
Nitish added,” All parties are concerned about votes but none is concerned about the nation.”
On the police lathi charge on RLSP chief and former Union minister Upendra Kushwaha in which he was injured on Saturday, Nitish said everything was on record who provoked police. Asking DGP Gupteshwar Pandey to direct police force for observing patience, the CM said the police react only when it is hit and when the police react only a senior officer could stop them.
On Congress president Rahul Gandhi’s rally at Gandhi maidan, Nitish said any party could make any promises before polls. He asked why during Congress or UPA governments at centre Patna University was not accorded central University status?
He said Rahul compromised his image by joining hands with those convicted in corruption cases (Lalu Yadav). ” It is the same person who had torn the ordinance and enhanced his image but nie corruption was no longer an issue for him.”

ntopng源码研究
ntopng是个啥?
ntopng 是一款实时的多协议网络流量监控工具。或许你会问,不是有wireshark啊这类基于的libpcap的各种sniffer工具,这牛逼在哪了?具体可参考官网
简单的总结几点ntopng的亮点:
低资源需求,高性能,基于pf_ring技术,似乎是同一个厂商的产物
监控各类协议,包括你没听过的,可以利用nDPI实现协议发现例如某p2p某IM (GFW的味儿了)
支持NetFlow/sFlow采集器,适配标准的网络设备
支持可视化分析/报表到出,很方便的查看网络连接和流量动向
可以交互式的查看历史流量数据,支持MySQL
为啥要研究它?
公司运维团队和安全团队想通过网络流量分析,审查流量和设备间的关系拓扑。
但是碍于分析能力不满足于需求,况且我司业务流量巨大,很可能需要进行改��,例如把数据打到Kafka,然后使用Spark Streaming进行分析,以WebUI的方式输出我们的业务能力等。虽然与软件开发商沟通了半个月商业license已经买了…
抛砖引玉一般的分析
关注环节:启动初始化、FlowDump、LUA交互、DB方法、协议字段映射关系
main.cpp 初始化
核心结构体:
涉及两个核心类:Ntop(相当于是骨架)、Perfs(相当于数据处理相关) 其中Ntop类的主要公有方法:
私有方法的声明代码:
Prefs类的主要公有方法:
Perf的类结构:
Prefs::Prefs(Ntop *_ntop) { num_deferred_interfaces_to_register = 0, cli = NULL; memset(deferred_interfaces_to_register, 0, sizeof(deferred_interfaces_to_register)); ntop = _ntop, sticky_hosts = location_none, simulate_vlans = false; local_networks = strdup(CONST_DEFAULT_HOME_NET "," CONST_DEFAULT_LOCAL_NETS); local_networks_set = false, shutdown_when_done = false; enable_users_login = true, disable_localhost_login = false; enable_dns_resolution = sniff_dns_responses = true, use_promiscuous_mode = true; resolve_all_host_ip = false, online_license_check = false; max_num_hosts = MAX_NUM_INTERFACE_HOSTS, max_num_flows = MAX_NUM_INTERFACE_HOSTS; data_dir = strdup(CONST_DEFAULT_DATA_DIR); install_dir = NULL, captureDirection = PCAP_D_INOUT; docs_dir = strdup(CONST_DEFAULT_DOCS_DIR); scripts_dir = strdup(CONST_DEFAULT_SCRIPTS_DIR); callbacks_dir = strdup(CONST_DEFAULT_CALLBACKS_DIR); config_file_path = ndpi_proto_path = NULL; http_port = CONST_DEFAULT_NTOP_PORT; http_prefix = strdup(""), zmq_encryption_pwd = NULL; instance_name = NULL; categorization_enabled = false, enable_users_login = true; categorization_key = NULL, zmq_encryption_pwd = NULL; es_index = es_url = es_user = es_pwd = NULL; https_port = 0; // CONST_DEFAULT_NTOP_PORT+1; change_user = true, daemonize = false; user = strdup(CONST_DEFAULT_NTOP_USER); http_binding_address = NULL; https_binding_address = NULL; // CONST_ANY_ADDRESS; httpbl_key = NULL, flashstart = NULL; cpu_affinity = NULL; redis_host = strdup("127.0.0.1"); redis_password = NULL; redis_port = 6379; redis_db_id = 0; dns_mode = 0; logFd = NULL; disable_alerts = false; max_num_alerts_per_entity = ALERTS_MANAGER_MAX_ENTITY_ALERTS; max_num_flow_alerts = ALERTS_MANAGER_MAX_FLOW_ALERTS; pid_path = strdup(DEFAULT_PID_PATH); packet_filter = NULL; enable_idle_local_hosts_cache = true; enable_active_local_hosts_cache = false; /* only cache active hosts on exit */ enable_probing_alerts = CONST_DEFAULT_ALERT_PROBING_ENABLED; enable_syslog_alerts = CONST_DEFAULT_ALERT_SYSLOG_ENABLED; enable_probing_alerts = enable_syslog_alerts = false; /* set later */ num_interfaces = 0, enable_auto_logout = true; dump_flows_on_es = dump_flows_on_mysql = false; enable_taps = false; memset(ifNames, 0, sizeof(ifNames)); dump_hosts_to_db = location_none; json_labels_string_format = true; #ifdef WIN32 daemonize = true; #endif export_endpoint = NULL; enable_ixia_timestamps = enable_vss_apcon_timestamps = false; enable_flow_activity = CONST_DEFAULT_IS_FLOW_ACTIVITY_ENABLED;
/* Defaults */ local_host_cache_duration = LOCAL_HOSTS_CACHE_DURATION /* sec */; non_local_host_max_idle = MAX_REMOTE_HOST_IDLE /* sec */; local_host_max_idle = MAX_LOCAL_HOST_IDLE /* sec */; flow_max_idle = MAX_FLOW_IDLE /* sec */;
intf_rrd_raw_days = INTF_RRD_RAW_DAYS; intf_rrd_1min_days = INTF_RRD_1MIN_DAYS; intf_rrd_1h_days = INTF_RRD_1H_DAYS; intf_rrd_1d_days = INTF_RRD_1D_DAYS; other_rrd_raw_days = OTHER_RRD_RAW_DAYS; other_rrd_1min_days = OTHER_RRD_1MIN_DAYS; other_rrd_1h_days = OTHER_RRD_1H_DAYS; other_rrd_1d_days = OTHER_RRD_1D_DAYS; host_activity_rrd_raw_hours = HOST_ACTIVITY_RRD_RAW_HOURS; host_activity_rrd_1h_days = HOST_ACTIVITY_RRD_1H_DAYS; host_activity_rrd_1d_days = HOST_ACTIVITY_RRD_1D_DAYS; housekeeping_frequency = HOUSEKEEPING_FREQUENCY;

mysql_host = mysql_dbname = mysql_tablename = mysql_user = mysql_pw = NULL;
has_cmdl_trace_lvl = false; has_cmdl_disable_alerts = false;
}
FlowDump
需要先关注一个最终的核心细节,PacketDumper.cpp
相关类方法:
调用pcap接口执行dump操作:
真正的FlowDump在 /ntopng/src/NetworkInterface.cpp 这里
Flow序列化为JSON:
存入MySQL,/ntopng/src/MySQLDB.cpp
LUA接口交互
用于注册LUA函数的结构体,Lua.cpp
注册过程的核心实现:
DB查询方法
这里没啥好看的,没关键玩意。
协议字段映射关系
搞清楚映射关系,我们就可以拿到它分析好的协议类别了,这也是它靠nDPI获得的强项。
进入MySQL表,看flowsv4的表结构,ipv6我们就不分析了。
这里的protocol字段类型都是整数,不好看出枚举值,还得是通过代码来分析:

Kolkata (West Bengal), [India], Dec 20 (ANI): Amid the on-going drama over the BJP's demand for holding Rathyatra in West Bengal, Calcutta High Court allowed Congress leader and senior advocate, Abhishek Manu Singhvi to join argument on behalf of DGP and ADG Law and Order in the case. This comes after the Chief Justice's bench agreed to hear the plea on Friday, which was filed by Mamata Banerjee-led West Bengal government on Wednesday, challenging the Calcutta High Court's single bench order permitting BJP's save democracy Rathyatra in the state. Earlier on Thursday, the court allowed the BJP to proceed with its Rathyatra in West Bengal, which is perceived in some political circles as a major setback to the Mamata government. The court gave permission to the BJP to hold three yatras in West Bengal and directed that the administration should ensure that there is no breach of law and order. Before the court's decision, the state government had refused permission for the proposed yatra citing intelligence reports of possible communal violence in areas where the BJP has planned the rallies.
