IPTraf is an ncurses-based IP LAN monitor that generates various network statistics including TCP info, UDP counts, ICMP and OSPF information, Ethernet load info, node stats, IP checksum errors, and others.
ifstat is a tool to report network interfaces bandwith just like vmstat/iostat do for other system counters. It can monitor local interfaces by polling the kernel counters, or remote hosts interfaces using SNMP.
Ethstatus is a console-based monitoring utility for displaying statistical data of the ethernet interface on a quantity basis. It is similar to iptraf but is meant to run as a permanent console task to monitor the network load.
ethstats works by parsing the /proc/net/dev file that the Linux kernel maintains, and thus utilizes a negligible amount of CPU time. ethstats shows the throughput of each device in both megabits per second and packets per second.
You can wake up WOL compliant Computers which have been powered down to sleep mode or start WOL compliant Computers with a BIOS feature.
WOL is an abbreviation for Wake-on-LAN. It is a standard that allows you to turn on a computer from another location over a network connection.
etherwake also supports WOL passwords.
TCPdump is a very powerful command line interface packet sniffer.
1. Install TCPDUMP
- To install TCPdump :
#apt-get install tcpdump
- To see the TCPdump dependencies:
#apt-cache depends tcpdump
tcpdump
Depends: libc6
Depends: libpcap0.8
Depends: libssl0.9.8
1. Network Settings
A. To configure your network interfaces with ifconfig.
- Static IP Address
#ifconfig [interface_name] [ip_address] netmask [mask]
ex :
#ifconfig eth0 192.168.1.15 netmask 255.255.255.0 broadcast 192.168.1.255
To configure the default gateway:
#route add default gateway [ip address] dev [interface_name]
ex :
#route add default gateway 192.168.1.1 dev eth0
Minicom adalah program komunikasi serial utk mengakses suatu jaringan atau perangkat melalui console port.
Tool ini mirip dengan Hyper Terminal, yg umumnya ada di Microsoft Windows System.
Ayo kita install Minicom :
#apt-get install minicom
Cek aktif serial ports :
#dmesg | grep tty
serial8250: ttyS0 at I/O 0×3f8 (irq = 4) is a 16550A
File /dev/ttyS0 permisinya harus di set read [...]
Netstat (NETwork STATistics) adalah command-line tool yg menyediakan informasi tentang konfigurasi jaringan dan aktifitasnya.
- Untuk menampilkan routing table :
#netstat -rn
-> -r : Kernel routing table
-> -n : Menampilkan alamat numerik.
- Untuk menampilkan statistik interface :
#netstat -i
-> -i : Interface
1. Network Settings
A. Seting network interface dengan ifconfig.
- Static IP Address
#ifconfig [interface_name] [ip_address] netmask [mask]
misal :
#ifconfig eth0 192.168.1.15 netmask 255.255.255.0 broadcast 192.168.1.255
nambahin default gateway :
#route add default gateway [ip address] dev [interface_name]
misal :
#route add default gateway 192.168.1.1 dev eth0
