It takes a traffic\-summary file (produced by +traffic_summary\&.pl) as input and produces a traffic\-model file that can be used by +traffic_replay +for traffic generation\&. +.PP +The model file summarizes the types of traffic (\*(Aqconversations\*(Aq between a host and a Samba DC) that occur on a network\&. The model file describes the traffic in a way that allows it to be scaled so that either more (or fewer) packets get sent, and the packets can be sent at a faster (or slower) rate than that seen in the network\&. +.SH "OPTIONS" +.PP +\-h|\-\-help +.RS 4 +Print a summary of command line options\&. +.RE +.PP +SUMMARY_FILE +.RS 4 +File containing a network traffic\-summary\&. The traffic\-summary file should be generated by +traffic_summary\&.pl +from a packet capture of actual network traffic\&. More than one file can be specified, in which case the traffic will be combined into a single traffic\-model\&. If no SUMMARY_FILE is specified, this tool will read the traffic\-summary from STDIN, i\&.e\&. you can pipe the output from traffic_summary\&.pl directly to this tool\&. +.RE +.PP +\-o|\-\-out OUTPUT_FILE +.RS 4 +The traffic\-model that is produced will be written to this file\&. The OUTPUT_FILE can then be passed to +traffic_replay +to generate (and manipulate) Samba network traffic\&. +.RE +.PP +\-\-dns\-mode [inline|count] +.RS 4 +How DNS traffic should be handled by the model\&. +.RE +.SH "EXAMPLES" +.PP +To take a traffic\-summary file and produce a traffic\-model file, use: +.PP +traffic_learner traffic\-summary\&.txt \-o traffic\-model\&.txt +.PP +To generate a traffic\-model from a packet capture, you can pipe the traffic summary to STDIN using: +.PP +tshark \-r capture\&.pcapng \-T pdml | traffic_summary\&.pl | traffic_learner \-o traffic\-model\&.txt +.SH "OUTPUT FILE FORMAT" +.PP +The output model file describes a Markov model estimating the probability of a packet occurring given the last two packets\&. +.PP +The count of each continuation after a pair of successive packets is stored, and the ratios of these counts is used to calculate probabilities for the next packet\&. +.PP +The model is stored in JSON format, and also contains information about the packet rate and DNS traffic rate\&. +.SS "Example ngram listing" +.PP +The following listing shows a contrived example of a single ngram entry\&. +.sp +.if n \{\ +.RS 4 +.\} +.nf + "ngrams": { + "ldap:0\etdcerpc:11": { + "lsarpc:77": 1, + "ldap:2": 370, + "ldap:3": 62, + "wait:3": 2, + "\-": 1 + }, [\&.\&.\&.] + } + +.fi +.if n \{\ +.RE +.\} +.PP +This counts the observed continuations after an ldap packet with opcode 0 (a bind) followed by a dcerpc packet with opcode 11 (also a bind)\&. The most common next packet is "ldap:2" which is an unbind, so this is the most likely packet type to be selected in replay\&. At the other extreme, lsarpc opcode 77 (lookup names) has been seen only once, and it is unlikely but possible that this will be selected in replay\&. +.PP +There are two special packet types here\&. "wait:3" refers to a temporary pause in the conversation, where the "3" pseudo\-opcode indicates the length of the wait on an exponential scale\&. That is, a "wait:4" pause would be about 2\&.7 times longer that a "wait:3", which in turn would be similarly longer than a "wait:2"\&. +.PP +The other special packet is "\-", which represents the limit of the conversation\&. In the example, this indicates that one observed conversation ended after this particular ngram\&. This special opcode is also used at the beginning of conversations, which are indicated by the ngram "\-\et\-"\&. +.SH "VERSION" +.PP +This man page is complete for version 4\&.19\&.5 of the Samba suite\&. +.SH "SEE ALSO" +.PP +\fBtraffic_replay\fR(7)\&. +.SH "AUTHOR" +.PP +The original Samba software and related utilities were created by Andrew Tridgell\&. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed\&. +.PP +The traffic_learner tool was developed by the Samba team at Catalyst IT Ltd\&. +.PP +The traffic_learner manpage was written by Tim Beale\&. |
