Proper server room mesti semua ada label dia....  Server room ni ada pakai proper rack etc ke?  

Anyway, kalau takde rack & label; terpaksa le kau ambik cable-tester & trace balik satu2 cable mana pegi mana....

BTW, server room kalau tak sejuk mau terbakar habis le...     Ambik le gambar, post kat sini....

betul tu.. kalu tak sejuk meraung la seber2 tu nak idup.. standard ar bilik seber sejuk.. tp ada gak yg tak sejuk aka seber tu nak kene jadi tukun la nanti...

then pasal cable2 tu, patutnya pn dilabelkan, kalu tak mmg masak la ko nak trace.. tgk la dkt switch ke apa ke, kat situ mesti dah dilabelkan.. cari penhujung cable kat dalam bilik seber ko tu...

kat opis aku ada beberapa switch yg mana kabel yg connect ke situ mmg x de label.mmg maut la nak trace kabel tu satu2 connect kat pc mana.
itu dlm opis yg ada dlm 30 pc.
kalo kat bilik server tu?huh mmg x akan dpt punya nak trace semua.
patutnya ada draft/buku yg bitau no port switch tu connect kat pc mana.
sbb kalo nak label rs mcm x praktikal plk.mn tau sticker dia tertanggal.m

akak tak amik networking...tapi nak nyibuk...
Apa kata-dapatkan network diagram your organisation. Kemudian identify box2 yg ada kat dalam bilik server tuh berdasarkan network diagram tuh. Rasanya better tanya kat your supervisor.

Biasanya info pasal network kat sesuatu organisation sepatutnya tak didedahkan kat umum seperti melalui forum ker. Sbb hacker menunggu jer apa2 info utk ceroboh the network.

Kalau ada rack yg sepatutnya, tak tanggal punya label dia...  Unless ada yg gatal tangan nak kopek le.  Semua ada proper tag yg guna plastik cover etc, bukannya pakai kertas & tape je....

Anyway, beli je network tester; kalau taknak penat ulang-alik, minta sorang lagi tolong...  Camni rupa dia...


Akak jadree00:  Internal connection je ni, bukan orang boleh tau pun IP address, port etc....  So, takde le sangat security risk dia....  Anyway, good point made too...  The biggest threat on any computer network is someone from the inside...  So, kalau tak tau something kena tanya org yg tau & never to reveal anything to outsiders....

Mula2 mmg la tak tau IP nyer. Once dah tau tuan umah nie keje kat mana, dah boleh teka IP address.

manalah tau mula2 citer pasal firewall lepas tuh terciter pasal OS apa guna. sikit2 info ter reveal. Last2...


p/s-akak tak pandai bab network nih...mungkin sbb tuh terlebih rasa seram jer bila tuan umah citer pasal info company kat outsider.

Noted....  Tapi, sunshine66 cuma nak tau camne nak trace cable dari satu end tu pegi mana je, so memang takde kena mengena dgn connection keluar....  Anyway, selalunya company hanya guna Streamyx yg guna dynamic IP; cuma company yg besar je yg pakai fixed IP...

But, macam yg saya cakap kat atas tu....  The best policy is to be a bit paranoid, tapi kalau paranoid terlebih memang takde org yg boleh tolong troubleshoot problem.  So, kena pandai balance le....

kalu tak silap dia nih sdg praktikal kat sebuah company besor oil &gas lagik, terbaca kat thread dia yg lain. rasanya unlikely company besor macam tuh pakai streamyx jer.

minta ampun tuan umah bcoz kak jad nie nyibuk jer....Orang dah tua camnielah prihatin lebih sikit kat adik2.
Tuan umah, silakan tanya soklan seterusnya.

Serius, rasa bersalah pulak macam halang orang nak belajar. Sekali lagi, mohon maaf. tk.

Oooo...  Gitu....  Takpe, soalan tetap soalan....  "There's no such thing as a stupid question"; lain le kalau memang niat nak tanya soalan camtu...  

Anyway, kalau company besar, lagi le unlikely dia boleh compromise security kat situ.  Semua server2 kat situ hanya orang tertentu saja yg tahu completely.  Takde diaorg nak reveal benda2 camtu kat budak practical or temporary staff.  Lagipun, internal network semua ada routing & port2 yg tertentu.  Lain le kalau memang berniat nak buat jahat & install some kind of sniffer or trojan kat dalam network...  Itu pun memang risky pun cuz ramai le mata2 yg selalu monitor network tu & memang pakar selok-belok network kat office tu....

FYI, even kat rumah saya pun saya monitor selalu network saya....  Nampak macam paranoid, tapi bagus sebab saya ada wireless router etc...  :-)


Anyway, so now akak dah tahu & memang akak patut concern pasal orang nak reveal too much info kat outsiders.  Mostly, the best policy is "need-to-know basis"...   

BTW, ke mana dah agaknya sunshine66 ni?

Basically your static IP to the internet, ports yg open untuk certain applications, VPN etc; then password & username....  Kalau setakat internal & physical cable etc takde masalah....  Lebih2 lagi kalau ada WiFi, cuz selalunya orang lock WiFi tapi ada gak sebab admin nak hide SSID WiFi tu cuz org boleh curi2 tap-in & analyse the traffic, then crack the WEP or WPA system yg Admin implement....  BTW, WiFi lagi senang cuz open sikit, kalau wired network nak kena physically intersect traffic kat cable tu...

BTW, sunshine tak reveal apa2 pun yg boleh bagi security risk....  Tapi, tengok contoh kat atas tu...  Ni namanya Social Engineering, so skrg I dah tau you keje practical kat O&G yg besar.  Tu dah narrow down the subject, kalau kita borak lagi dah tentu I boleh dapat tempat kerja U, either kat Exxon or Petronas etc....     Kejap je, tak susah pun...

Kalau nak trace host (server or PC gi masuk hub or switch mana) try buat mcm nie.  Hang panggil member hang sorang.  Sorang tunggu kat host/pc/server sorang lagi tunggu kat switch.  Cabut cable utp kat host tu. Then masukkan balik.  Then cabut balik.  Buat process tu banyak kali.  Kawan satu lagi tgk lampu mana yang padam/ada balik kat switch/hub tu.  Yang lampu dok padam/nyalalah port yang host tu guna.  Ada faham.

Ini cara nak jimat cost tak payah pakai tester.  Tapi jangan buat mcm tu kat kritikal server plak.  Naya kena menjawab nanti.  Huhuhuh....
