cisco catalyst2900、3500系列交换机密码破解方法
1.拔掉交换机的电源线
2。用超级终端和控制线连到交换机,超级终端的设置是:
9600 baud rate
No parity
8 data bits
1 stop bit
No flow control
3。按住交换机前面板的“mode”按钮,插上电源线,当端口1上面的灯不亮后,放松“mode”按钮;
4。这时超级终端上应该显示:
The system has been interrupted prior to initializing the flash
file system.
The following commands will initialize the flash file system, and
finish loading
the operating system software:
flash_init
load_helper
boot
5。输入flash_init
6。输入load_helper
7. 输入dir flash:
这时显示:
Directory of flash:
2 -rwx 843947 Mar 01 1993 00:02:18 C2900XL-h-mz-112.8-SA
4 drwx 3776 Mar 01 1993 01:23:24 html
66 -rwx 130 Jan 01 1970 00:01:19 env_vars
68 -rwx 1296 Mar 01 1993 06:55:51 config.text
1728000 bytes total (456704 bytes free)
8。输入rename flash:config.text flash:config.old
9.输入boot,重新启动系统
10。系统启动完后显示:Continue with the configuration dialog?
[yes/no] :
输入N
11.输入enable
12.进入enable模式后,输入rename flash:config.old flash:config.text
13。接着按以下步骤操作:
Switch# copy flash:config.text system:running-config
Source filename [config.text]? (press Return)
Destination filename [running-config]? (press Return)
14 。接着按以下步骤操作:
switch#configure terminal
switch(config)#no enable secret
switch(config)#no enable password
路由器口令破解
1、启动路由器,在30秒那按ctrl+break,进入rommon模式
System Bootstrap, Version 12.1(3r)T2, RELEASE SOFTWARE (fc1)

C2600 platform with 65536 Kbytes of main memory
PC = 0xfff0ab6c, Vector = 0x500, SP = 0x80004884
monitor: command "boot" aborted due to user interrupt
rommon 1 >
2、然后输入
rommon 1 > confreg 0x2142
You must reset or power cycle for new config to take effect
rommon 2 > reset
3、路由器会重新启动
