3. Menganalisa servis yang membuka port di komputer lokal.
root@ubuntu:/home/kel2# netstat –listenning |more
Active internet connections (w/o services)
Proto Recv-Q Send-Q Local Address Foreign Address State
Active UNIX domain sockets( w/o servers)
Proto Ref Cnt Flags Type State I_Node Patch
Unix 4 [ ] DGRAM 6618 /dev/log
Unix 2 [ ] DGRAM 7939
Unix 2 [ ] DGRAM 7763
Unix 2 [ ] DGRAM 7492
Unix 3 [ ] STREAM CONNECTED 7298 @/com/ubuntu/upstart
Unix 3 [] STREAM CONNECTED 7295
Unix 3 [] DGRAM 6508
Unix 3 [] DGRAM 6507
Unix 3 [] STREAM CONNECTED 6458 @/com/ubuntu/upstart
Unix 3 [] STREAM CONNECTED 6454
4. Menganalisa servis yang membuka port dikomputer anda dengan perintah network mapper.
root@ubuntu:/home/kel2# nmap localhost
Starting Nmap 5.21 (http://nmap.0rg) at 2012-10-04 13.16 WIT
Nmap scan report for localhost (127.0.0.1)
Host is up (0.0000135 latency)
All 1000 scanned Ports on Localhost (127.0.0.1) are closed
Nmap done : IP Address (1host up) Scanned in 0.19 seconds
5. Menganalisa IP asal, IP tujuan,port tujuan dalam sebuah koneksi.
-pada terminal 1
root@ubuntu:/home/kel2# ssh 202.9.69.2
kel2@202.9.69.2’s password:
password tidak di masukkan dan langsung pindah ke terminal 2, dan hasilnya :
root@ubuntu:/home/kel2#netstat | grep ESTABLISHED
tcp 0 0 10.17.0.193:35003 lib.polsri.ac.id:ssh ESTABLISHED
PENJELASAN :
IP asal Dan IP tujuan telah terhubung dalam sebuah koneksi. Saat masuk ke terminal 1 dengan perintah ctrl+alt+F1, akan diminta password. Namun setelah masuk pada terminal 2, tidak akan diminta password.
6. Menganalisa IP asal, IP tujuan,port tujuan dalam sebuah koneksi.
Perintahnya:
root@ubuntu:/home/kel2#tcpdump -1 eth0
tcpdump: verbse output suppressed, use –v or –vv for full protected decode
listening on eth0,link-type EN10MB (Ethernet),capture size 65535 bytes
