10 POINT TO SHARE

Anyway, I was just trying to build a list of what it takes to become a successful contractor (in network engineering area or technical consulting). With my limited experience as contractor, here it is:

1. Build the reputation. The most important, I believe, are the integrity and responsibility
2. Result oriented. The work must be done successfully no matter what, within the agreed timeline
3. Adaptable, flexible, able to handle the pressure and sudden changes in the project
4. Possess extensive experience in different types of project with multiple roles
5. Able to work independently, but at the same time able to work as part of the team
6. Good communication skill and can easily blend with customers from any types, anywhere, in any circumstances
7. Specialize and focus in one technology area but know other stuff to certain level. For example, expert in Core IP/MPLS network but understand as well the access layer, security, physical layer, data center and so on
8. Able to work as multiple roles: engineer, consultant, architect, project manager etc
9. Always update the skills, fast and continuous learner. Willing to invest on skill update, lab, and any tools that can assist in delivering the work
10. Know how to market yourself: social networking, keep the contacts with previous customers, always update the CV, etc

FACEBOOK DIBLOK ?

Facebook (FB), siapa yang tak kenal dengan FB hingga di kantor kadang2 kerjaan terbengkalai gara2 FB, he..he.. dan kadang2 dari HRD minta ke IT Dept untuk memblok akses ke FB (kejam amat hiks hiks)

Ada juga yang hanya boleh akses pada jam istirahat, jadi pilihannya mau makan istirahat atawa mau fb he..he..

tapi ada caranya neh supaya bisa akses FB, ya semacam istilah
Banyak jalan menuju Roma

pakai HP (sekarang beli hp pasti sudah di bundle dengan gratis akses facebook sekian waktu he..he..)
kalau dari kantor coba ke uncle google dan cari dengan keyword proxy untuk akses facebook

ini ada sedikit contohnya :

Reset password ROOT in DEBIAN

This is one of the problem faced by many person’s“what if i lost the root password”First thing that comes in mind is “use single user mode” but the answer is NO.
coz debian takes the system security to one more level up and by default ask’s for the root password.


so the BIG QUESTION IS HOW TO proceed further

follow these steps

1) on grub-boot prompt.
press “e” to enter edit mode

2) then press downarrow to reach the line that starts with “kernel “
press “e” again

3) at the end of this line type in “init=/bin/sh” or “/bin/bash”

4) then press enter to make that change and press “b” to boot

in a few seconds you will be on your “#” prompt

5) only one step left
“mount -o remount rw /”

this step is necessary coz in this case root file system is mounted as read only.

6) finally type “passwd” and you get the screen to change the password

and then type in “init 6? or “reboot”

NOTE FOR TECHNICAL USERS
those who are looking for the technical details, the main work is the init command that we passed as an argument to kernel, it told kernel to specifically run the command specified in parameter instead of working on normal routine.

TRICK = if you have any program you wish to run instead of this then you can do that too using init command only.

Remote PC With Command Prompt

RCMD, the remote command prompt

One of the most powerful parts of windows is the command line interface (cmd.exe). I have done things from directory listings to adding users locally, editing registry and even as far as manipulating windows services.

Being able to do all this from command line is great, but when you have multiple machines at different locations, It is nice to do some remote work from time to time. In comes PSEXEC from Microsoft’s Sysinternals. using PSEXEC and a little know-how on writing batch files, I created a batch file that will allow me to use the command line interface on remote PC while the user is still logged on.

The batch is as follows

psexec //%1 -u domainname\user -p password c:\windows\system32\cmd.exe

pause

saving this batch file as c:\windows\rcmd.bat will allow you to start the run command and type rcmd computername and you should get a command prompt for that PC (if you are an administrative user on that PC)

This is great for spot checks or quick changes, but when you want to make changes, but when you need to make changes on more than one PC, you can create a batch file with these changes and use PSEXEC to run the batch on a list of workstations.

First you want to create a text file (I call mine hosts.txt) and input each computer name or IP of the workstation (one host per line)

Next is to open up a command line and type in the following

psexec @hosts.txt -u domain\user -p password -c batchfile.bat

To keep things neat and tidy, I generally creatediscriptive folder with psexec, the batch file, the hosts file and a batch including this command called runme.bat.

Script Ambil File ke FTP Server Secara Otomatis

Script untuk download file dari FTP Server
Untuk yang sudah mengenal pemrograman Shell, script berikut bisa digunakan untuk mengambil file dari FTP server secara otomatis. Semisal menjadwalkan pengambilan file pada jam,tanggal ataupun hari tertentu, dengan bantuan crontab.

ftp -in
open HOSTNAME
user USER PASSWORD
COMMAND_LINE1
COMMAND_LINE2
COMMAND_LINE3
get FILENAME1
get FILENAME2
bye

Misal kita pengen konek ke IP 10.34.19.1, dengan user perator password:ngawur dan mendownload file dengan nama Laporan_20080301.txt dari direktori /home/operator/laporan, script nya kurang lebih seperti ini :

ftp -in
open 10.34.19.1
user operator ngawur
cd /home/operator/laporan
bin
hash
get Lap_20090214.txt
bye
Selamat Mencoba.

Belajar Cisco (VLAN)

vlan aktif
berdasarkan port
mac address
protokol
subnet
aplikasi

dhcp aktif default-router meragukan
routing protokol baru rip ,igrp eigrp,ospf,bgp
lalu lakukan konek si dengan jaringan lan perusahaan
maka diapakai NAT pada router agar client vlan di router kita terdeteksi
lalu dilakukan accest list lalu policy
ini syntaksnya:
setting vlan
switch
conf t
vlan database
vlan100
vlan200
vlan300
int range g1/0/8 g1/0/10
swtichport access vlan100
no shut
int range g1/0/11 g1/0/13
swtichport access vlan100
no shut
int range g1/0/13 g1/0/16
swtichport access vlan100
no shut
int g1/0/1
switchport mode trunk

router
conf t
int g0/1.100
encapsulation dot1q 100
ip address 192.168.10.254 255.255.255.0
int g0/1.200
encapsulation dot1q 200
ip address 172.16.20.254 255.255.255.0
int g0/1.300
encapsulation dot1q 100
ip address 10.0.30.254 255.255.255.0

static setiap komputer yang terhubung dengan switch tergantung vlan nya dengan mengeset ip address secara manual

dynamic setiap komputer hanya mengeplug lan kabelnya router akan memberikan ip secara otmatis

ip dhcp pool vlan100
network 192.168.10.0 255.255.255.0
default-router 192.168.10.254

ip dhcp pool vlan200
network 172.16.20.0 255.255.255.0
default-router 172.16.20.254

ip dhcp pool vlan300
network 10.0.30.0 255.255.255.0
default-router 10.0.30.254

tidak dibutuhkan router protokol karena terhubung directly ke setiap port

bagaimana cara agar masingmasing vlan tersebut terhubung dengan internet sedangkan kita tau setiap vlan memiliki ip yang berbeda
pada penerapan kali ini router berada dibawah switch yang terhubung lagi dibawah sebuah router yang menghubungkan jaringan dengan internet
dengan di bawah router tersebut menggunakan vlan lagi yakni 10.3.0.1 gateway nya
maka
kita harus mengeset network address translation
dapat diset
1.static
2.dynamic
1.dynamic ip
2. dynamic port atau yang disebut Port Address Translation
kita mencoba port address translation
konfgure di routernya
access-list 13 192.168.10.0 0.0.0.255
access-list 13 172.16.20.0 0.0.0.255
access-list 13 10.0.30.0 0.0.0.255
ip nat inside source list 13 inteface g0/0 overload
int g0/1.100
ip nat inside
int g0/1.200
ip nat inside
int g0/1.300
ip nat inside
int g0/0
ipnat outside

jangan lupa kita harus memberi tahu router kita gateway internetnya
dengan mengkonfigure
ip route 0.0.0.0 0.0.0.0 10.3.0.1
ssetelah terhubung dengan internet kita hedak mencoba untuk melakukan bandwith limit dengan mengkonfigure router
konfigure pada router
masuk interface dahulu
rate-limit input 64000 8000 8000 conform-action transmit exceed-action drop
access list konfiguration
