To verify your installation you can check if the folder /etc/ansible/ exists with that content:Packet capture files can be opened and analyzed offline with tcpdump or any. When tcpdump finishes capturing packets, it will report counts of: packets captured'' (this is the number of packets that tcpdump has received and processed) packets received by filter'' (the meaning of this depends on the OS on which you're running tcpdump, and possibly on the way the OS was configured - if a filter was specified on the.
When used properly, it can give you a detailed view of packets as they traverse interfaces on a Linux host. Sudo apt-get install tcpdump. Drwxr-xr-x 2 root root 4096 Nov 29 22:39 rolestcpdump allows you to capture network traffic on one or more interfaces on the host. If you execute the TCPdump command with the -i flag you can name an interface and the TCPdump tool will start capture that. Capture packets from a specific interface. Once the TCPdump tool is installed, you can continue to browse following commands.
Properly Tcpdump How To Use It
However, I'm experiencing a (probably) simple problem but, as I'm not such an experienced user in these issues, I would like to ask for some help.-rw-r-r- 1 root root 1016 Nov 29 22:39 hosts-rw-r-r- 1 root root 19155 Nov 29 22:39 ansible.cfgWith that steps done, we almost can start the tcpdump.yml ansible-playbook – finally 🙂 ConfigurationFirst thing to mention is that for now I don’t care about ansible roles. At the moment I'm trying to install libpcap 1.0.0 and tcpdump 4.0.0 as they are tagged as the latest releases. It provides several ways how to use it for DNS analysis. For debian it can be installed directly from the debian repository: apt-get install tcpdump TCPdump allows write a sniff to file or display it realtime. TCPdump is preinstalled on many linux distributions.

SummaryI hope I was able to answer some of your questions and you feel ready to start your tcpdump with Ansible.If you have problems, don’t hesitate to contact me.If you want to know more about it, join my Slack Workspace or send me an email. For this arctile I’ve decided to use the way with user+pw.Here is the screenshot of the successful execution to one of my webserver (I used root just for this demo -)):While this command was running on my AWS instance, I’ve double checked on my webserver if tcpdump is running:Tcpdump 9741 9740 0 10:40 pts/1 00:00:00 /usr/sbin/tcpdump -G 10 -W 1 -i eth0 -s 0 -w /tmp//packet_capture_vmd17544_1518255638.pcap tcp port 443After the playbook was finished, my /export/tmp/ansible/ folder on my AWS instance looked like this:-rwxr-xr-x 1 root root 12421 Feb 10 09:41 packet_capture_vmd17544_1518255638.pcap.gzThe playbook takes the tcpdump, zip it, change the file permission to be able to copy it, copy the logs to your server and delete the file finally from the remote machine. With “-k” ansible will ask me for the SSH passwordYou can also do all of it with SSH keys. With “-u daniel” I am specifying the user name I want to connect with via SSH
