Port ini biasanya digunakan untuk web server, jadi ketika user mengetikan alamat IP atau hostname di web broeser maka web browser akan melihat IP tsb pada port 80,
2. Port 81, Web Server Alternatif
ketika port 80 diblok maka port 81 akan digunakan sebagai port altenatif hosting website
3. Port 21, FTP Server
Ketika seseorang mengakses FTP server, maka ftp client secara default akan melakukan koneksi melalui port 21 dengan ftp server
4. Port 22, SSH Secure Shell

Si Pengganggu Kinerja Komputer
Apa sih pengganggu komputer? Pertanyaan itu kalo diajukan sebenarnya kurang spesifik.. Seharusnya yang harus ditanyakan yaitu, "Apa saja pengganggu Kinerja Komputer itu?"
Ada banyak hal yang mengganggu komputer, tapi "si pengganggu" cuma ada beberapa.. Antara lain:
Virus: bisa pasif, bisa akif, biasanya memanfaatkan kelengahan user.
Spyware: namanya juga spy, untuk memata-mata aktivitas yang dilakukan dalam sistem operasi tersebut, mungkin termasuk password tracing ya?
Worm: ini sih freestyle-virus, auto run, auto replication.

Worm Kido alias Downadup
Kategori Antivirus, Virus, security | 5,571 views | 59 Comments
Worm Downadup
Sebenarnya sejak beberapa hari ini sempat membaca/mendapat informasi mengenai worm Downadup di beberapa blog tentang security/virus/antivirus, tetapi saya biarkan saja karena dikira hanya berita worm biasa. Tetapi ternyata banyaknya yang memberitakan tentang worm ini karena memang worm ini cukup “dahsyat” dan canggih.
Berdasarkan perkiraan dari F-Secure, salah satu variant baru worm ini sudah menginfeksi hampir 9 juta komputer hanya dalam waktu 4 hari. Jumlah yang tidak sedikit untuk worm yang belum lama muncul.
Nama asli Worm ini adalah Worm:W32/Downadup.gen dan mempunyai berbagai nama alias seperti : W32/Conficker.worm.gen (Symantec), Mal/Conficker (Sophos) , Worm: Win32/Conficker (Microsoft). Selain itu juga dikenal dengan nama Conflicker dan Kido (contoh nama : Worm: W32/Downadup.gen!A, Net-Worm.Win32.Kido.ih ). Worm ini termasuk kategori Malware yang berjalan di windows 32 -bit, makanya disebut W32.
Penyebaran worm
Penyebaran worm ini melalui berbagai cara, seperti Network/jaringan yang di share atau password yang lemah, juga bisa menyebar dengan membuat file pemicu autorun.inf yang di copykan ke USB Flashdisk (drive) atau media removable lainnya. Maka sebaiknya fitur autorun windows ini dimatikan selain untuk mencegah penularan berbagai virus lainnya.
world-map
Worm ini memanfaatkan celah keamanan Windows untuk menginfeksi korbannya, seperti artikel sebelumnya Ada apa dengan Security Update Windows MS08-067. Worm akan membuat folder dengan nama acak di dalam directory RECYCLER ( yang digunakan Recycle Bin untuk menyimpan file yang telah dihapus ) juga menduplikasi diri di berbagai tempat lainnya.
Efek Worm Downadup
Dan ini mungkin yang membuat saya menulis artikel ini, beberapa pengunjung ebsoft menuliskan komentar bahwa mereka tidak bisa membuka situs-situs antivirus, dan bisa jadi penyebabnya adalah worm ini.
Worm ini mampu mengubah/menambah fungsi internal windows (TCP) untuk memblok akses situs-situs keamanan (security/antivirus), dengan memfilter alamat yang mempunyai karakter/text tertentu. Dan untuk menghilangkan efek tersebut tidak mudah, karena boleh dibilang sudah tingkat low level programming.
Worm ini didesign untuk melindungi diri dari deteksi antivirus dengan menggunakan teknik tertentu yang jarang digunakan, melindungi diri dari upaya untuk di hapus, mematikan windows update, restore point sebelum infeksi, mematikan trafik jaringan tertentu, mengoptimalkan fitur windows Vista untuk memudahkan penyebaran, mampu menginjeksi explorer.exe, svchost.exe dan services.exe dan lainnya.
Situs-situs yang di blok cukup banyak, meliputi web yang menggunakan text seperti berikut ( bisa di blok atau selalu memunculkan pesan Time Out ketika membuka situsnya) :
* virus
* spyware
* malware
* rootkit
* defender
* microsoft
* symantec
* norton
* mcafee
* trendmicro
* sophos
* panda
* etrust
* f-secure
* kaspersky
* f-prot
* nod32
* eset
* grisoft
* avast
* avira
* comodo
* clamav
* norman
* pctools
* rising
* sunbelt
* threatexpert
* wilderssecurity
* windowsupdate
* avp
* avg
Selain itu juga situs-situs security lainnya.
Bagi yang belum terkena, maka untuk menghindari bisa download update Untuk Windows XP Microsoft Security Update MS08-067 (Patch for fixing the security hole). Sedangkan jika komputer sudah terinfeksi, maka bisa download remover tool, baik dari F-Secure atau Bitdefender dibawah ini.

What is the difference between an Ethernet hub and switch?
What is the difference between an Ethernet hub and switch?
Although hubs and switches both glue the PCs in a network together, a switch is more expensive and a network built with switches is generally considered faster than one built with hubs. Why?
When a hub receives a packet (chunk) of data (a frame in Ethernet lingo) at one of its ports from a PC on the network, it transmits (repeats) the packet to all of its ports and, thus, to all of the other PCs on the network. If two or more PCs on the network try to send packets at the same time a collision is said to occur. When that happens all of the PCs have to go though a routine to resolve the conflict. The process is prescribed in the Ethernet Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol. Each Ethernet Adapter has both a receiver and a transmitter. If the adapters didn't have to listen with their receivers for collisions they would be able to send data at the same time they are receiving it (full duplex). Because they have to operate at half duplex (data flows one way at a time) and a hub retransmits data from one PC to all of the PCs, the maximum bandwidth is 100 Mhz and that bandwidth is shared by all of the PC's connected to the hub. The result is when a person using a computer on a hub downloads a large file or group of files from another computer the network becomes congested. In a 10 Mhz 10Base-T network the affect is to slow the network to nearly a crawl. The affect on a small, 100 Mbps (million bits per scond), 5-port network is not as significant.
Two computers can be connected directly together in an Ethernet with a crossover cable. A crossover cable doesn't have a collision problem. It hardwires the Ethernet transmitter on one computer to the receiver on the other. Most 100BASE-TX Ethernet Adapters can detect when listening for collisions is not required with a process known as auto-negotiation and will operate in a full duplex mode when it is permitted. The result is a crossover cable doesn't have delays caused by collisions, data can be sent in both directions simultaneously, the maximum available bandwidth is 200 Mbps, 100 Mbps each way, and there are no other PC's with which the bandwidth must be shared.
An Ethernet switch automatically divides the network into multiple segments, acts as a high-speed, selective bridge between the segments, and supports simultaneous connections of multiple pairs of computers which don't compete with other pairs of computers for network bandwidth. It accomplishes this by maintaining a table of each destination address and its port. When the switch receives a packet, it reads the destination address from the header information in the packet, establishes a temporary connection between the source and destination ports, sends the packet on its way, and then terminates the connection.
Picture a switch as making multiple temporary crossover cable connections between pairs of computers (the cables are actually straight-thru cables; the crossover function is done inside the switch). High-speed electronics in the switch automatically connect the end of one cable (source port) from a sending computer to the end of another cable (destination port) going to the receiving computer on a per packet basis. Multiple connections like this can occur simultaneously. It's as simple as that. And like a crossover cable between two PCs, PC's on an Ethernet switch do not share the transmission media, do not experience collisions or have to listen for them, can operate in a full-duplex mode, have bandwidth as high as 200 Mbps, 100 Mbps each way, and do not share this bandwidth with other PCs on the switch. In short, a switch is "more better."
