Eric Leblond	20a8b9dbe5	unix-manager: add unix command socket and associated script ... This patch introduces a unix command socket. JSON formatted messages can be exchanged between suricata and a program connecting to a dedicated socket. The protocol is the following: * Client connects to the socket * It sends a version message: { "version": "$VERSION_ID" } * Server answers with { "return": "OK|NOK" } If server returns OK, the client is now allowed to send command. The format of command is the following: { "command": "pcap-file", "arguments": { "filename": "smtp-clean.pcap", "output-dir": "/tmp/out" } } The server will try to execute the "command" specified with the (optional) provided "arguments". The answer by server is the following: { "return": "OK|NOK", "message": JSON_OBJECT or information string } A simple script is provided and is available under scripts/suricatasc. It is not intended to be enterprise-grade tool but it is more a proof of concept/example code. The first command line argument of suricatasc is used to specify the socket to connect to. Configuration of the feature is made in the YAML under the 'unix-command' section: unix-command: enabled: yes filename: custom.socket The path specified in 'filename' is not absolute and is relative to the state directory. A new running mode called 'unix-socket' is also added. When starting in this mode, only a unix socket manager is started. When it receives a 'pcap-file' command, the manager start a 'pcap-file' running mode which does not really leave at the end of file but simply exit. The manager is then able to start a new running mode with a new file. To start this mode, Suricata must be started with the --unix-socket option which has an optional argument which fix the file name of the socket. The path is not absolute and is relative to the state directory. THe 'pcap-file' command adds a file to the list of files to treat. For each pcap file, a pcap file running mode is started and the output directory is changed to what specified in the command. The running mode specified in the 'runmode' YAML setting is used to select which running mode must be use for the pcap file treatment. This requires modification in suricata.c file where initialisation code is now conditional to the fact 'unix-socket' mode is not used. Two other commands exists to get info on the remaining tasks: * pcap-file-number: return the number of files in the waiting queue * pcap-file-list: return the list of waiting files 'pcap-file-list' returns a structured object as message. The structure is the following: { 'count': 2, 'files': ['file1.pcap', 'file2.pcap'] }	12 years ago
