It might happen on your CCNA exam, it might happen on your production network - but sooner or later, you're going to have to perform password recovery on a Cisco router or switch. This involves manipulating the router's configuration register, and that is enough to make some CCNA candidates and network administrators really nervous!
It's true that setting the configuration register to the wrong value can damage the router, but if you do the proper research before starting the password recovery process, you'll be fine.
Despite what some books say, there is no "one size fits all" approach to Cisco password recovery. What works on a 2500 router may not work on other routers and switches. There is a great master Cisco document out on the Web that you should bookmark today. Just put "cisco password recovery" in your favorite search engine and you should find it quickly.
The following procedure describes the process in recovering from a lost password on a Cisco 2500 router. As always, don't practice this at home. It is a good idea to get some practice with this technique in your CCNA / CCNP home lab, though!
The password recovery method examined here is for 2500 routers.
An engineer who finds themselves locked out of a router can view and change the password by changing the configuration register.
The router must first be rebooted and a "break" performed within the first 60 seconds of the boot process. This break sequence can also vary depending on what program is used to access the router, but is the usual key combination.
The router will now be in ROM Monitor mode. From the rom monitor prompt, change the default configuration register of 0x2102 to 0x2142 with the o/r 0x2142 command. Reload the router with the letter i. (As you can see, ROM Monitor mode is a lot different than working with the IOS!)
This particular config register setting will cause the router to ignore the contents of NVRAM. Your startup configuration is still there, but it will be ignored on reload.
When the router reloads, you'll be prompted to enter Setup mode. Answer "N", and type enable at the router> prompt.
Be careful here. Type configure memory or copy start run. Do NOT type write memory or copy run start!
Enter the command show running-config. You'll see the passwords in either their encrypted or unencrypted format.
Type config t, then use the appropriate command to set a new enable secret or enable password.
Don't forget to change the configuration register setting back to the original value! The command config-register 0x2102 will do the job. Save this change with write memory or copy run start, and then run reload one more time to restart the router.
This process sounds hard, but it's really not. You just have to be careful, particularly when you're copying the startup config over the running config. You don't want to get that backwards! So take your time, check the online Cisco documentation before starting, get some practice with this procedure with lab equipment, and you'll be ready for success on the CCNA exam and in your production network!

How to Connect a USB Modem Wireless Router Ethernet
I currently have a USB broadband modem. I purchased a wireless router which has ethernet connections. Currently, the modem is plugged into my computer downstairs which is running Windows 98, therefore, it won't bridge the connections to my computer upstairs(XP). I can't update to XP because a family member wont 'risk' it.
Can I connect the USB broadband modem to my wireless router using a complicated selection of cable adapters ie ethernet to USB (I cant find a USB TO ETHERNET adapter). If this is not possible, if I plug the USB modem into my XP computer, can I bridge the connections to my Win 98 computer using the XP computer as the host?
I think their is Ethernet to USB out their currently but not USB to ethernet. I dont see any reason why you should not be able to hook up your USB modem to your XP computer and use it as a bridge to the 98 computer.
Of course, it would be nicer to have an all-in-one unit, but you can accomplish your goal with this equipment. You cannot use cable adapters to convert the modem's USB into Ethernet. USB needs drivers to operate, and Ethernet connections do not provide those drivers to the device. you could also connect the modem to the XP machine and bridge connections, yes. but you can leave the system the way it is and configure it to run smoothly like this:
If I had the hardwear in front of me, it would be easier to provide specifics... but i can probly give you an idea of what to do. There are only 2 steps here:
1. configure an internet gateway.
2. configure the router.
And the rest is easy.
1. Set up the internet machine to SHARE AN INTERNET CONNECTION (you can use the wizard if you want, or just enable Internet Connection Sharing), which will turn the 98 into an internet gateway. that gateway needs an IP address designated, however. In essence, the 98 machine will be the internet server, so the IP of the 98 machine is the IP of the gateway. Assign an address, for example: 192.168.1.1 to the 98 machine. the "192.168" is important, and the last strings you can stretch on, but for the sake of ease lets keep it small. *TIP* the subnet mask will always be 255.255.255.0. okay that takes care of the host machine.
2. after you have an internet gateway, connect the wireless router, and console (or IP) in to the settings, usually by going into internet explorer and typing 192.168.0.1 into the address bar, and look for a slot for Internet Gateway. Type the address assigned in step 1. thats that for the router. (there may be other settings necessary for your specific network, and if there are, be sure to configure those.)
Lastly a few housekeeping tasks. make sure the workgroup for both machines is identical. I usually use MSHOME as the workgroup. Also make sure that on the XP machine, your IP address is set to "Automatically Obtain IP address", also known as DHCP.

Membuat kinerja ponsel Sony Ericsson menjadi optimal
Dengan memperbarui firmware ponsel, pengguna akan mendapatkan versi software terbaru yang persis sama seperti firmware di ponsel baru yang dijual di pasaran dengan tipe sama. Diharapkan, pada software versi terbaru, segala kekurangan, kelemahan, cacat software yang terdapat pada firmware versi lawas akan teratasi di versi terbaru.
Untuk bisa memperbarui firmware, pengguna cukup menyiapkan seperangkat komputer, aplikasi SEUS, koneksi internet dan kabel data yang biasanya sudah disertakan dalam paket penjualan ponsel. Komputernya disarankan berprosesor Intel Pentium 4 2.0 GHz atau lebih tinggi, memiliki ruang harddisk 300 MB, memori 512MB, punya satu slot USB yang kosong. Selain itu di komputer sudah terpasang Internet Explorer 4 atau yang lebih baru, dan Adobe Flash Player versi 8 ke atas.
Langkah Instalasi
1. Langkah pertama yang perlu dilakukan adalah mengunjungi alamat http://www.sonyericsson.com/cws/support/softwaredownloads/detailed/updateservicedengan browser. Klik link Download now untuk mengunduh SEUS terbaru. File instalasi Update_Service_Setup-2.8.12.9.exe (Sony Ericsson Update Service versi 2.8.12.9) berukuran lebih dari 25MB.
2. Bila telah diunduh, SEUS harus segera diinstalasikan. Klik ikon Update Service pada desktop atau menu start. Saat Layanan Pemutakhiran dijalankan, aplikasi ini akan mengakses internet untuk mengunduh konten yang diperlukan untuk menjalankan layanan ini. Proses ini mungkin perlu beberapa menit, bergantung kecepatan koneksi internet Anda.
3. Pilih bahasa yang Anda sukai dan ikuti petunjuk yang muncul. Khusus untuk P900 atau P910, jika PC suite sudah di-instal, klik dua kali Phone Connection dan hilangkan tanda cek pada port USB.
4. Di halaman sambutan Layanan Update, klik tombol Mulai. Saat muncul perjanjian layanan, setujui perjanjian tersebut. Setelah itu, pilih model ponsel yang Anda punya sesuai dengan gambar. Lanjutkan dengan memilih tipe ponsel sesuai dengan gambar yang muncul di layar. Tak lama kemudian akan muncul petunjuk cara menghubungkan ponsel ke komputer dalam posisi siap di-flashing. Ikuti petunjuk tersebut dengan teliti sesuai dengan tahapannya. Tahapan ini berbeda-beda tergantung pada jenis ponsel.
5. Jika Anda telah sampai pada tahap akhir, aplikasi SEUS akan secara otomatis melanjutkan proses dengan mendeteksi versi firmware di ponsel Anda dengan versi terbaru yang tersedia di internet. Apabila versi terbaru telah tersedia, Anda akan diajak untuk melanjutkan ke proses selanjutnya.
6. Proses berikutnya akan memakan waktu yang agak lama, tergantung pada koneksi internet Anda. SEUS akan mengunduh firmware ponsel yang ukurannya berkisar 10-65 MB. Pada tahapan ini pastikan arus listrik tidak terputus dan internet tidak mati.
Saat Sinyal mencoba trik ini, kebetulan koneksi internet tiba-tiba terputus di posisi 67 persen. Panik, sudah pasti, apalagi aplikasi SEUS tidak dapat dimatikan dengan alasan proses pemutakhiran sedang berlangsung. Jika Anda mengalami hal ini, matikan saja proses Update Service dengan paksa melalui Task Manager dan ulangi proses dari awal.
7. Bila pengunduhan telah selesai, SEUS secara otomatis akan melanjutkan ke tahapan selanjutnya, yaitu flashing firmware ponsel. Lagi-lagi Anda harus memastikan arus listrik tidak terputus. Tapi kali ini lebih serius. Jika dalam proses flashing terjadi pemadaman listrik atau koneksi kabel dari PC ke ponsel terputus, bisa dipastikan ponsel tidak dapat menyala setelahnya. Ini disebabkan firmware ponsel terkorupsi. Oleh karena itu, gunakan PC yang dilangkapi dengan UPS, atau notebook yang baterainya masih baik saat flashing guna menghindari hilangnya asupan listrik secara tiba-tiba saat proses flashing. Tenang saja, proses flashing tidak akan berlangsung lama, hanya beberapa menit. Selanjutnya, Anda sudah bisa menikmati ponsel “baru”.
TIPS
Jangan lupa untuk melakukan back-up penuh terhadap data-data di ponsel sebelum melakukan pemutakhiran. Setelah proses flashing, semua data akan hilang. Untuk keperluan backup, Anda dapat menggunakan aplikasi Sony Ericsson PC Suite atau aplikasi pihak ketiga, seperti My Phone Explorer dan sejenisnya.

Blogging Tips on What You Should Do or Not Do
Are you looking for effective blogging tips? You’ve come to the right place. It’s true that any individual can upload or open a blog online for the world to read and see. However, this is not a very easy thing.
Maintaining a blog in the long run is a bit difficult especially if you want to have a successful one. You can actually find blogging platforms for free online and most of the platforms are simple to use. Even a technophobic writer can use such blogging platforms but it is difficult to find qualities like originality, enthusiasm, creativity, patience, and spare time.
Many people who tried writing blogs had initially high passions for blogging but after some time, they neglected their blogs until it finally died. There are only a few bloggers who maintain weekly posts for a large number of subscribers. If you want to know their secrets to maintaining successful blogs for many years, just read on.
The first one is to write only about the things you know and love. Never write about something that you hardly know of and what you don’t like. Most individuals who want to write blogs often choose topics that are of great interest to other people, and of course, themselves. Make sure that you choose a topic that you’re interested and eliminate those that you don’t like, even if the topic is said to generate more traffic. As long as you’re passionate about the topic, go on and write a blog about it.
When you’re writing a blog, make sure that you have a new, funny, and smart insight. If you’re about to write something that was already written by other bloggers, stop writing about it and instead, try to think about a new and better idea or insight. Choose another topic instead.
The next helpful tip is to be creative. As always, creativity is very important in maintaining successful blogs. Once you’ve posted a certain idea, don’t repeat it all over again. Adapting fresh ideas of other bloggers is definitely not a good idea. If you want to gain the loyalty of your subscribers, you must always try to be original in every blog you write. This way, your loyal subscribers will stay hooked on the blogs you make.
It is also good if you always consider your readers. Your blogs are like featured columns and so you must update at least weekly. Try to add new posts so that you will not be forgotten. If in case you can’t write new posts, try to inform your readers.
Try to socialize with the readers. You can encourage them to take an active part in your blog by adding polls and asking questions. They will be more than glad to add personal comments. If you want to improve your blogging skills, you must also read the blogs of other bloggers.
