Lab 1

Topics of the lab:

TCPDUMPING: tcpdump is a data-network packet analyzer computer program that runs under a command line interface. It allows the user to display TCP/IP and other packets being transmitted or received over a network to which the computer is attached.

SNMPWALK: SNMP walk is an SNMP application that uses SNMP GETNEXT requests to collect SNMP data from network and infrastructure SNMP-enabled devices, such as switches and routers.

REMOTE ACCESS: The act of being able to access and work on a different PC than the one you are currently using.

SNMP SETUP

Community string: public

to add a user to sudo privileges, do: usermod -aG wheel [username]

To get rid of root login #vi /etc/ssh/sshd_config Switch "Yes" to "No" and uncomment out the "Root Login" section

To snmpwalk, type : snmpwalk -Os -c (community string) -v2c (target)

snmpwalk requires proper snmp setup, you can do this via the roles and features method on the management box

To add remote services, just simply go through the installer on your management box and add them through there.

When TCP dumping, make sure that have what your listening for sending data towards the listening box.

IP ADDRESSES DO MATTER!!!
