Oinsa ita bele loke facebook husi server block Access denied

Atu loke Access denied www.facebook.com iha opsaun 2 proxy husi mozila no DNS Open

stop Access Denied (policy_denied) Your system policy has denied access to the requested URL

ida ne halo ita sai barauk wainhira loke link website nebe ita atu loke liu-liu ba link www.facebook.com hahahahahahha

ita sempre hasoru husi media teknologi internet problema Access Denied,dala ruma husi konten website nebe ita loke iha konten pornografia,

1.opsaun 1 ok maluk sira keta fera ulun ba ida ne,ne fasil ba ita atu loke Access Denied www.facebook.com

oinsa ita atu resolve problema ne no uja maneira oin-oin,ok mai ita hare hamutuk

seacrh iha google no loke link website proxy gratis exemplo hanesan

http://webproxy.to

http://hidemyass.com

http://webproxy.ca

http://www.freshproxylist.net

oinsa ita atu uja link website proxy ne ok

1.loke firefox

2.click options

3.click advanced - network- settings - click manual proxy configuration ense proxy IP adress open ho 212.3.190.77 ho port 8080 maibe keta haluha IP ho port ne hau foti husi nasaun china bele loke website ka link http://webproxy.to

2.iha opsaun 2 bele uja mos DNS Open

fungsaun DNS pronto atu simu no loke website nebe blokir,tan ida ne mak hau halo maneira DNS Open husi google

1.hanehan logo windows + R iha keyboard (start Run)ketik: cmd >enter)no ketick ncpa.cpl. ok

2.sei mosu pagina Network Connections,no click kanan ba Network Connections nebe sei acktiva,hili properties > internet protocol service 4 (TCP/IPV4)

3.no hatama use the following DNS server addresess no ense Preffered DNS server 8.8.8.8 dan Alternate DNS server 8.8.4.4.

laiha problema wainhira ita hakarak koko no aprende ba opsaun hotu-hotu ema bele tansa ita labele.hahahahha obrigadu ba atensaun keta haluha fo komentariu iha okos

Networking

Oinsa Desemvolve DHCP server ubuntu server

Dhcp signifikadu husi dynamic host configuration protocol.mak protocol nebe atende fo ip address no mos atribusaun seluk ba komputador klinte ho otomativu. Dhcp server hanesan solusaun maneja ip address iha rebe nebe bo'ot.

Mai Estuda hamutuk konaba Cisco Packet Tracer

Oinsa atu fahe rede uja route ba Lan A no Lan B

Loke Cisco .

desenu.1

Ok.diak nia sei mosu tuir mai nee..

desenu.2

Ita sie hili komponentu nebe mak ita uja mak hanesan :

→ komputador

→ router

desenu.3

4. Agora Ita klik dala rua ba router... → tab CLI

ita setting uluk ba Lan A.

nia interfaca fa 0/0 ip mak : 192.168.0.1 net mask 255.255.255.0

router>

router>enable

router#conf t

router#interface fa 0/0

router#ip address 192.168.0.1 255.255.255.0

router#no shutdown

router#exit (sai husi configura fa 0/0)

router>exit (sai husi configura terminal)

router>write (rai = save)

router>exit (taka configura)

Oinsa ita bo'o sira kria fali ba Lan B....??????????

…..TPC?????

5. Nia resultadu ikus liu mak sai hanesan ne'e.....!!!!

KOINHESIMENTU KONA BA KOMPONENTE SIRA IHA KOMPUTADOR

MOTHERBOARD

Motherboard mak komponente komputador nian ne’ebe ita atu tau ka monta komponente sira seluk komputador nian hanesan Processor, Video Card, Sound Card, Hard Disk, RAM, Power Supply no seluk seluk tan. Motherboard ne’e nia funsaun atu halo ligasaun ba komponentes ida-idak hodi bele halo komunikasaun ba malu. Kada motherboard iha nia espesifikasaun rasik, espesifikasaun hanesan processor saida mak fo apoiu no kapasidade maksimal RAM hira ne’ebe hetan apoiu husi motherboard.

PROCESSOR

Karik komputador ida kompara ho ema, processor hanesan kakutak ba ema ne’e.

Processor ka CPU (Central Processing Unit) mak komponente komputador ne’ebe nia serbisu atu ezekuta instrusaun ka hala’o kalkulasaun. Molok sosa processor ida imi tenke buka hatene uluk, socket processor modelo saida mak ita nia motherboard ne’e iha, karik socket AM2, socket LGA 775, ka seluktan.

RAM

RAM mak abreviasaun husi Random Access Memory, mak komponente komputador ida ne’ebe ho nia funsaun atu rai dokumentu provizoriu husi programa ida ne’ebe sei lao hela no dokumentus hirak ne’e bele asesu ho acak ka random. Molok ita sosa RAM ida, ita tenke hatene uluk Slot RAM modelo saida mak ita nia motherboard iha, karik SDRAM, DDR, DDR2, ka seluktan.

Hard disk mak komponente komputador, fatin ne’ebe rai dokumentus pemanente. Hard disk ho kapasidade bo’ot iha ita nia komputador maka ita bele rai dokumentus barak liutan. Molok ita sosa hard disk ita tenke buka hatene interface hard disk modelo saida mak ita nia motherboard iha, karik IDE, SCSI, SATA, ka seluktan.

POWER SUPPLY

Kompara ho kareta ne’ebe la lao bainhira laiha mina, nune’e mos komputador ida la moris ka la funsiona bainhira laiha power supply ka PSU (Power Supply Unit). Power supply mak komponente ida husi komputador ne’ebe ho funsaun atu oferese forsa eletrisidade ba komponenete sira seluk hanesan motherboard, hard disk, optical disk drive, no sira seluktan.

OPTICAL DISC DRIVE

Maske la ho optical disc drive komputador bele moris ka funsiona, maibe kuandu laiha komponente ida ne’e, komputador hanesan izolado husi mundo liur nian, izolado husi mundu liur signifika katak ita iha difikuldades baihnira iha tempo ruma ita hakarak kopia dokumentus, instala programa, hare filmajem VCD ka DVD, ne’ebe rai iha CD ka DVD.Optical Disc Drive bele hanesan CD-ROM, DVD-ROM, DVD-RW, Blue-Ray, ka seluktan. Molok sosa optical disk drive ida, ita tenke buka hatene uluk interface modelu saida mak ita nia motherboard iha, karik IDE, SATA, ka seluktan.

MONITOR

Monitor mak komponente komputador ne’ebe ho nia funsaun atu hatudu figura ne’ebe fo sai (output) husi video card. Monitor komputador barak ne’ebe iha merkadoria agora dadaun ne’e mak monitor CRT (monitor tabung) no monitor LCD maibe agora dadaun ema barak prefere uza monitor LCD (liu-liu iha edifisiu sira) tamba monitor ida ne’e laos deit ho modelu ne’ebe modernu, maibe mos iha forsa seluk mak poupa espasu no poupa eletrisidade.

KEYBOARD

Keyboard mak komponente komputador ho nia funsaun hanesan instrumentu hodi hakerek buat ruma. Alem de keyboard standard, keyboard komputador agora ne’e iha modelu oin-oin, hanesan keyboard mini, keyboard fleksibel ne’ebe bele lulun, keyboard wireless ne’ebe bele uza bluetooth, no seluktan.

MOUSE

Mouse mak komponente komputador ne’ebe ho nia funsaun atu muda kursor iha monitor no atu klik buat ruma hanesan butaun (tombol) iha aplikasaun programa ida. Mouse mos iha modelu oin-oin, iha mouse standard, mouse ba jogus (gaming), mouse wireless ne’ebe uza Bluetooth, no seluktan.

Saida Mak DCHP

Saida Mak DCHP ??

DCHP liafuan badak husi Dynamic Configuration Host Protocol. DCHP mak protokolu nebee nia basiku iha client/server nee uja fasil liu wainhira atu halo alokasaun fatin IP nian iha rede nian (Network). Rede local nebee la uja DCHP tenki kria ka halo fatin IP nebee manual baa komputador hotu-hotu. Karik DCHP monta iha rede local ida, entaun kmputador hotu-hotu nebee mak iha hela koneksaun rede ida sei hetan fatin IP nebee otomatiku no server DCHP. Laos fatin IP det, parameter rede barak nebee mak sei hetan ka foo husi DCHP, hanesan default gateway no DNS server.

DCHP defini baa iha RFC 2131 no RFC 2132 nebee pubilka tiha ona husi Internet Engineering Task Force. DCHP hanesan ekstensaun ida husi protokolu Bootsrapt, Protokolu (BOOTP).

DCHP nia Lalaok

Tamba DCHP nudar protocol nebee uja iha client/server ida nee maka DCHP iha buat rua, buat rua nee mak DCHP Server no DCHP Client.

DCHP server hanesan makina nebee halao servisu nebee bele foo fatin atu “aluga” (menyewakan) fatin IP no informasaun TCP/IP selu-seluk tan baa kliente nebee husu ou nia hakarak. Iha systema operasaun oi-oin baa rede nebee hanesan Windows NT Server, Windows 200 Server, Windows 2003 Server ou GNU/Linux nebee iha serbii hanesan nee. DCHP kliente (Client) makina nebee kliente nebee halao servisu nuudar sasan nebee mamar (Software) kliene DCHP sira nebee belee halao komunikasaun ho DCHP Server. Systema operasaun barak liu kliente rede iha (Windows NT Workstation, Windows 200 Profesional, Windows XP, Windows Vista ou GNU/Linux) nebee iha sasan nebee mamar (Software) hanesan nee
