You get right to the point without missing important details. I have been struggling with TCPDUMP for a while. I found it difficult to read and didn't know when it could be of use when troubleshooting. Now I do, thank you.

@ernestomarcos11 2 года назад

you all probably dont give a damn but does anyone know a tool to log back into an Instagram account? I somehow forgot my password. I would love any tricks you can offer me.

@odeus7164 2 года назад

@@ernestomarcos11 unfortunately that question has nothing to do with networking and no there and no tools available for security reasons. You’ll have to either figure out what the password is, reset it if you can’t remember or make a new account.

@Mark Raphael thanks for your reply. I got to the site through google and im in the hacking process now. I see it takes a while so I will reply here later when my account password hopefully is recovered.

@ernestomarcos11 2 года назад

In TCP Dump for example something is not working and you want to troubleshoot that issue so what is a syntax of TCP Dump?

@ajaydalvi2887 6 лет назад

Does TCPDUMP show the drop packet logs, packet is getting in from inside interface but on outside interface there is no logs when run TCPDUMP on external interface.

@ijasahmed5514 2 года назад

That clearly means it is dropped...i dont think we can see the dropped packets on tcpdump...

@MyMrrakesh 6 лет назад

Hi, Thanks for your tutorial. One thing i am confused about your diagram and IP table which has been mentioned. Those are not matching from network diagram. I watched complete video and i got confuse which situation i will execute the command for tshoot.

@MyMrrakesh 6 лет назад

As per your network diagram Eth0 IP add > 192.168.130.198 & 199 But management IP address is 192.168.223.100 (Why both are different network. ) Eth1 IP add > 11.11.11.12 & 11 (I am not able to find this ip address range and eth0 port not in the diagram). Eth 2 IP add > 192.168.223.198 & 199 (Its fine). Eth 3 IP add > 10.11.12.198 & 199 (This IP in the diagram showing different.) Kindly go through the diagram and IP address table once and make me understand topology with IP address. Thanks in advanced :)
