Telnetlab

Ip address of server is checked using ifconfig command

Telnet is connected from client to server

From tcpdump we can see the password of telnet is exposed and is not secure.

When ssh is used password cannot be seen using tcpdump.

Tcpip:

Using nping we generated tcp syn packets and attacked port 23 of the victim.

Next we generated tcp rst packets and attacked the server

In next sequence we generated ack packets and using hex script to attack the server

Network-basics

Ip addresses of both machines can be seen

servers can ping each other and this also added each other into their arp entries.

Server 2 can access server 1 using ssh in which we can see using tcp dump tcp packets.

Routing-basics

Ip address of all the machines can be seen

Workstation 3 cannot connect to other servers on the same gateway

Workstation 2 can easily ping google

Workstation 3 still cannot get to google

Iptable rules to show nat entry is for workstation 1 with ip 192.168.1.2

remote machine can access workstation 1 from nat through gateway machine.

Remote ws connected to gateway

Bird-bgp

Dumps can be seen in wireshark

E4 cannot be reached from anywhere

Configured r4 for e4 but still it has some errors even after correct configuration...
