Posted on by

KB ID 0000573

Problem

If you cannot get access to your router, or you have bought, found or been given one, and you cannot access it. The simplest thing to do it to reset to to factory settings. Once the Router has been reset its settings will be as follows;

DrayTek Default Username and Passwords

Model
Username
Password
Vigor Rev. ALL admin admin
Vigor 2600 admin {blank}
Vigor 2800 {blank} {blank}
Vigor 2900+ admin admin
Vigor 3300 draytek 1234

Note: The Router will set itself up with a static IP address http://192.168.1.1) and will act as a DHCP server (Make sure your network card it set to get its address automatically.

 

Solution

Warning: Make sure you have all your Routers settings, before you start, especially your ADSL username and password (ring your ISP and confirm) before resetting the Router as all these settings will be WIPED!

Factory Reset DrayTek Vigor: Option 1 (If you do not know the password)

Note: Model shown is a DrayTek Vigor 2800

1. with the router powered on in normal operation the power light should be blinking (slowly)

2. Use a pen, to depress the factory reset button on the rear of the device.

3. The power light will blink rapidly.

4. Release the factory reset button.

Factory Reset DrayTek Vigor: Option 2 (If you know the password)

If you can log in but just want to wipe the settings, and revert to factory defaults.

1. Connect to the web management console and navigate to, System Maintenance > Reboot system > Tick “Using factory default configuration”.

Factory Reset DrayTek Vigor: Option 3 (If you know the password)

If you can log in but just want to wipe the settings, and revert to factory defaults.

1. Familiarise yourself with the DrayTek Vigor firmware upgrade procedure. But use the firmware that ends in .RST NOT the firmware that ends in .ALL. (Note: The .all firmware just updates the firmware but keeps the settings).

Dell PowerEdge – PERC RAID Card Importing / Using ‘Foreign’ Disks

Posted on by

KB ID 0000639 

Problem

I bought some SAS disks from eBay to go in my Power Edge 2900 Server, and scratched my head for a while trying to get the PERC RAID controller to use them. I could only see them marked as ‘Foreign’. Probably because they did not have their original config ‘wiped’ off them before I bought them.

Solution

1. Boot the server, Press CTRL+R when prompted, then press ‘C’ to enter the Configuration Utility.

WARNING: DONT clear the config on the controller or you lose ALL your Virtual Disks / Arrays.

2. Select the controller > F2 > Foreign Config > Clear > Confirm.

3. You can now add the disk(s) as a new Virtual Disk.

4. I’m just presenting one 300GB SAS disk as RAID0 here.

Cisco Catalyst Password Recovery / Reset

Posted on by

KB ID 0000496 

Problem

The title is a bit of a misnomer, we are not going to recover the password, we are simply going to change the password to one we know.

Solution

Note: This procedure works on models, 2900, 2940, 2950, 2955, 3500XL, and 3550. Before you start connect the the device with a console cable and terminal emulation software, the procedure is the same as the one I’ve outlined here.

1. Power the switch off >press and hold the “Mode” button > Power on the switch.

2. For 2900, 3500XL and 3550 Switches release the mode button when the 1x LED light goes out (all the other port lights will remain lit). For a 2940 and 2950 Switch release the mode button after the “Stat” LED goes out. For a 2955 switch press CTRL+BREAK.

3. On screen you should see the following.

[box]

Base ethernet MAC Address: 00:0b:be:78:a2:00
Xmodem file system is available.
The password-recovery mechanism is enabled.

The system has been interrupted prior to initializing the
flash filesystem. The following commands will initialize
the flash filesystem, and finish loading the operating
system software:

flash_init
boot

[/box]

4. Type “flash_init” then when it has ran type “load_helper”

[box]

switch: flash_init
Initializing Flash...
flashfs[0]: 18 files, 3 directories
flashfs[0]: 0 orphaned files, 0 orphaned directories
flashfs[0]: Total bytes: 15998976
flashfs[0]: Bytes used: 4386304
flashfs[0]: Bytes available: 11612672
flashfs[0]: flashfs fsck took 17 seconds.
...done Initializing Flash.
Boot Sector Filesystem (bs:) installed, fsid: 3
switch: load_helper

[/box]

5. Next we need to make sure that the config.text file is in flash memory type “dir flash:”

Note: don’t forget the colon on the end or it will error and say “Permission Denied”.

[box]

switch: dir flash:
Directory of flash:/

2 drwx 192 <date> c3550-i9q3l2-mz.121-11.EA1a
17 -rwx 255 <date> info
18 -rwx 255 <date> info.ver
19 -rwx 5448 <date> config.text
20 -rwx 5 <date> private-config.text
21 -rwx 2364 <date> vlan.dat

11612672 bytes available (4386304 bytes used)

[/box]

6. We are now going to change the name of the config file so when the switch boots it will start with no configuration, then we can boot the switch.

[box]

switch: rename flash:config.text flash:config.backup
switch: boot

[/box]

7. Eventually when the switch boots it will ask if you want to configure it, say no.

[box]

Model revision number: G0
Motherboard revision number: A0
Model number: WS-C3550-24-SMI
System serial number: CAT0650Y1VR

--- System Configuration Dialog ---

Would you like to enter the initial configuration dialog? [yes/no]: no

[/box]

8. At this point we can go to enable mode, change the name of the config.text file back again, and load it into memory (press Enter to accept the default filenames).

[box]

Switch>enable
Switch#rename flash:config.backup config.text
Destination filename [config.text]?
Switch#copy flash:config.text system:running-config
Destination filename [running-config]?
5448 bytes copied in 0.728 secs

[/box]

9. Finally you can remove the password, and reset it to whatever you want, and save the new config.

[box]

HostName#conf t
Enter configuration commands, one per line. End with CNTL/Z.
HostName(config)#no enable secret
HostName(config)#enable password thisisthenewpassword
HostName#wr mem
Building configuration...
[OK]
HostName#

[/box]
