Jgn Menggunakan Device Operational, Kalo ada apa2 bisa Dipecat!!! jgn salahin gw

Gw coba praktek make switch CISCO CATALYST 2900

—-start here—

lihat tombol2 yg ada di switch tsb, disana ada tombol “MODE

ketika switch br di idupin cepet2 pencet tombol MODE tsb, smp muncul kotak di bawah ini

The system has been interrupted prior to

initializing the flash filesystem.

The following commands will initialize

the flash filesystem, and finish loading the operating

system software:

flash_init

load_helper

boot

smp muncul prompt :

switch:

trs masukin command :

switch:load_helper

selanjutnya masukin command di bawah ini :

switch: flash_init

Initializing Flash... flash

fs[0]: 18 files, 2 directories flash

fs[0]: 0 orphaned files, 0 orphaned directories flash

fs[0]: Total bytes: 7741440 flash

fs[0]: Bytes used: 3966464 flash

fs[0]: Bytes available: 3774976 flash

fs[0]: flash

fs fsck took 7 seconds. ...done initializing flash.

Boot Sector Filesystem (bs:) installed,

fsid: 3 Parameter Block Filesystem (pb:) installed,

fsid: 4

berfungsi utk menginisialisasi flash system image pada switch :

lalu kita bs cek isi switch dengan menggunakan perintah “dir” (kok sama ky windows 😀 )

nah folder yg mau kita rubah adalah folder flash

selanjutnya spt ini

switch: dir flash:

Directory of flash:/  2

-rwx  2664051   <date>    c2950-i6q4l2-mz.121-11.EA1.bin 3

-rwx  269       <date>    env_vars 4

-rwx  2296      <date>    vlan.dat 5

-rwx  3441      <date>    config.text 6

-rwx  5         <date>    private-config.text 7

drwx  704       <date>    html 19

-rwx  109       <date>    info 20

-rwx  109       <date>

info.ver  3774976 bytes available (3966464 bytes used)

Dari hasil diatas dapat kita liat file IOS disimpan disini, data2 vlan serta startup-config yaitu config.text.
file config.text inilah yg diload pada saat switch booting. Nah, thinking of something? kalo kita bisa
dapetin/edit itu file, maka bisa kita manipulasi tuh enable secret. that’s how it works.

here’s the main method, ……………
kita rename file config.text menjadi config.text.old
caranya adalah sebagai berikut:

switch: rename flash:config.text flash:config.text.old

----Cek Hasil-----

switch: dir flash:

Directory of flash:/  2

-rwx  2664051   <date>               c2950-i6q4l2-mz.121-11.EA1.bin 3

-rwx  269       <date>               env_vars 4

-rwx  2296      <date>               vlan.dat 5

-rwx  3441      <date>               config.text.old 6

-rwx  5         <date>               private-config.text 7

drwx  704       <date>               html 19

-rwx  109       <date>               info 20

-rwx  109       <date>               info.ver  3774976 bytes available (3966464 bytes used) switch:

dapat dilihat bahwa file config.text berubah menjadi config.text.old

setelah itu ki restart switch dengan cara:

switch: boot

setelah command boot di execute :

switch: boot Loading

Would you like to enter the initial configuration dialog? [yes/no]:

look at the result, like the new switch huh?
yaap karena kita udah manipulasi file startup-config, sehingga switch menanyakan “Would you like to enter the initial configuration dialog? [yes/no]:”

so what we gonna do then??

ketik “no” untuk membaypass initial configuration mode.

the next step as follows:

Switch>en

Switch#dir

Directory of flash:/      2

aha kita sudah masuk ke mode “enable” tanpa hrs make pwd, selanjutnya terserah anda 😀 😀
