slm dostlarım cisco 3700 serisi bir router ım var veee parolasını hatırlamıyorum hyper terminal ile bağlantı kurduğumda bembeyaz bir sayfa geliyor. ne yapmam lazım şifremi kıracam bu yöntemle kırmam doğru adımmı olur? yardımlarınız için teşekkür ederim.

zaten başka türlü kıramazsınız. hyperterminal ile konsol üzerinden kıracaksınız. peki router ile ilgili bilgiler yazılar geliyor mu? bazı yazılar gelmesi lazım ve en azından router açılımı sağlandığında password istemesi lazım, bu ekran gelmiyorsa com bağlantınızı kontrol edip bağlı olduğunuzdan emin olun.
password ve herhangi bir yazı gelmiyor fakat hyper terminal bağlı olduğunu sol alt köşede yazıyor.bağlantı seçeneğini com1 yerine com3 ü seçince klavyeden birşeyler yazabiliyorum fakat ekranda yazdığım yazılardan başka bir şey gelmiyor.
Slm;
su komut'a bir goz atalimmi... "seek and destroye", bu komutu yazarken tab key komutu tamamlamaz, comutu hard code etmek zorundasiniz, yani gizli ve tehlikeli bir komut....bu komutun amaci password recoveryi disable etmesidir.
n_s_p_r(config)#no service password-recovery
umarim ufukta birkac gemi daha gormenize yardimci olurWhen you configure the router, ensure you see this message:
router1(config)#no service password-recovery
WARNING:
Executing this command will disable password recovery mechanism.
Do not execute this command without another plan for
password recovery.
Are you sure you want to continue? [yes/no]: yes
router1(config)#end
This is a message you could see if the configuration is unsuccessful:
router1(config)#config-register 0x2142
router1(config)#no service password-recovery
Please reset the ignore config bit (0x40) in config-register.You cannot change the configuration register in order to ignore the start-up configuration after ROMMON security has been enabled. In order to change the configuration register to ignore the start-up configuration, you must issue the service password-recovery command.
router1(config)#no service password-recovery
router1(config)#config-register 0x2142
Password recovery is disabled, can not enable diag or
ignore configuration.When the no service password-recovery command is configured, you see this message during boot up:

*There are only a few methods you can use to recover from a lost password, but---d-i-k-k-a-t-> all of them destroy the start-up configuration<-----------------.
1------------------>Routers that have nonvolatile RAM (NVRAM) chips can be removed and reseated. The NVRAM is implemented with battery-backed up static RAM (SRAM). If you remove the SRAM, the contents of NVRAM are erased as well as the no service password-recovery configuration. Be sure to use proper anti-static procedures when you handle the NVRAM. Some of these routers are 3640 and 3660.
2------------------->Other routers, such as the 1700, 2600, and 3620, use an electrically erasable programmable read-only memory (EEPROM) in order to hold the configuration. The EEPROM does not erase when you remove it.
3-------------------->Another method is to reload or boot the router with console access, and press CTRL-BREAK within five to ten seconds of the Cisco IOS software image decompressing or roughly when the "Image text-base:... " part of the banner begins. You are then prompted to reset the router to factory default (erase start-up configuration).

ee peki. benim hyper terminal ile bağlantımdan niye birşey gelmiyor ekrana yardımcı olurmusunuz??
gelip bizim yapacak halimiz yok. konsol kablonuzun sağlam olduğunu kontrol edin. ayrıca hyperterminal ayarlarını da kontrol edin. 9600 8N1 gibi ayarlar olması gerekiyor. Hangi com porttan bağlı ise portu da belirtin. Hyperterminal ayarlarınızı paylaşır mısınız?
günaydın
peki bu telnet bağlantısında da geçerlimi yoksa sadece console bağlantısında mı bu yöntem uygulanabilir?
