UPnP on Cisco router

I need to enable UPnP on my Cisco 3640 router using the command prompt(telnet), does anyone have a solution?

    UPnP is used to automatically open ports in a firewall to allow traffic through. What IOS version are you using? Since this is a router and not a firewall are you expecting to get an access-list updated automatically?

It doesn't support UPnP, it is a commercial product.

I need to access my NetgearN150 from a command prompt as the GUI is not working can someone tell me if there are telnet or ssh commands available for this unit? The following lists the systems I am...


I think if you're using stock firmware you might be out of luck using ssh.
Still try telnet. (telnet IP address) if it was enabled before on the router (disabled by default.) If you have Win 7 you have to enable telnet in "Programs and Features/Turn Windows features on or off".
Find more info here.
Anyways - I would first try a 30-30-30 reset.
  1. Hold reset button for 30 sec.
  2. pull power whilst holding the reset button for another 30 sec.
  3. plug in power and keep the reset button holding for an additional 30 sec.
Let me know how that goes.

Where is the password located at


Hey, the Netopia routers do not have a default username and password. If a password is already set up, you might need to reset the router.

In order to log into the router you need to Telnet into it.
If you are using Windows XP, you can start Telnet from Start>Accessories>Communications>Telnet

if you are using Windows Vista or Windows 7, Telnet is not enabled by default. You need to enable it first. You can quickly re-enable Telnet by following these steps:

Start
Control Panel
Programs And Features
Turn Windows features on or off
Check Telnet Client
Hit OK

After that you can start Telnet via Command Prompt. (or the Start menu)

then once you get into the Telnet Console, type in:
192.168.1.1

and the router interface will open up and let you chanfge settings.

Hi i have 1841 router what is the default user name password for this i tryed with user name passowrd as cisco but is saying that no user cisco pls help me



  • Follow these steps in order to recover your password:
    1. Attach a terminal or PC with terminal emulation to the console port of the router.
      Use these terminal settings:
      • 9600 baud rate
      • No parity
      • 8 data bits
      • 1 stop bit
      • No flow control
    2. If you can access the router, type show version at the prompt, and record the configuration register setting.
      Note: The configuration register is usually set to 0x2102 or 0x102. If you can no longer access the router (because of a lost login or TACACS password), you can safely assume that your configuration register is set to 0x2102.
    3. Use the power switch in order to turn off the router, and then turn the router back on.
      Important Notes:
      • In order to simulate this step on a Cisco 6400, pull out and then plug in the Node Route Processor (NRP) or Node Switch Processor (NSP) card.
      • In order to simulate this step on a Cisco 6x00 with NI-2, pull out and then plug in the NI-2 card.
    4. Press Break on the terminal keyboard within 60 seconds of power up in order to put the router into ROMMON.
      If the break sequence does not work, refer to Standard Break Key Sequence Combinations During Password Recovery for other key combinations.
    5. Type confreg 0x2142 at the rommon 1> prompt in order to boot from Flash.
      This step bypasses the startup configuration where the passwords are stored.
    6. Type reset at the rommon 2> prompt.
      The router reboots, but ignores the saved configuration.
    7. Type no after each setup question, or press Ctrl-C in order to skip the initial setup procedure.
    8. Type enable at the Router> prompt.
      You are in enable mode and should see the Router# prompt.
    9. Type configure memory or copy startup-config running-config in order to copy the nonvolatile RAM (NVRAM) into memory.
      Important: Do not type copy running-config startup-config or write. These commands erase your startup configuration.
    10. Type show running-config.
      The show running-config command shows the configuration of the router. In this configuration, the shutdown command appears under all interfaces, which indicates all interfaces are currently shut down. In addition, the passwords (enable password, enable secret, vty, console passwords) are in either an encrypted or unencrypted format. You can reuse unencrypted passwords. You must change encrypted passwords to a new password.
    11. Type configure terminal.
      The hostname(config)# prompt appears.
    12. Type enable secret password> in order to change the enable secret password. For example:
      hostname(config)#enable secret cisco
    13. Issue the no shutdown command on every interface that you use.
      If you issue a show ip interface brief command in privilege EXEC mode, every interface that you want to use should display up up. For example:
      Router#show ip interface brief
    14. Type config-register configuration_register_setting>. Where configuration_register_setting is either the value you recorded in step 2 or0x2102 . For example:
      hostname(config)#config-register 0x2102
    15. Press Ctrl-z or end in order to leave the configuration mode.
      The hostname# prompt appears.
    16. Type write memory or copy running-config startup-config in order to commit the changes.

How do you perform a "factory reset" on a cisco c2912-lre-xl ?


From a console login, should look something like this:

Switch>

Go to privileged EXEC mode with the command "Enable"

Switch#
Enter the command "erase startup-config"

It will prompt you to confirm
When you confirm, it will bring you back to this prompt

Switch#

Now, enter the command "reload"
It will prompt you to confirm. And after a reload, you will be brought back to a screen that looks like this:

Press ENTER to begin

NOTE: if you are telnetting to the switch it WILL boot you out as you cannot keep an established telnet session without VTY line passwords and those are cleared by this process.

ALSO NOTE: This will NOT erase your VLAN data, VLANs are stored in a special file in Flash on a Cisco switch and SHOULD NOT be erased without professional help as there is a risk of destroying the IOS load on the switch.

How to reset password of pix 506e


Hi,

You only need a PC and a serial terminal. First of all you need to know the PIX software version you run. After that you must go to Cisco web page and get from there the utility for the password recovery corresponding to your version of software.

After that you must connect to the PIX console port. Press ESC key after the PIX is booting and a special prompt it will appear (monitor>). Issue the "interface" command to specify which interface to be active. Inside interface it will be the default one. Then use the command "address" to go with the IP address of the above interface. After that, you will need also an TFTP server where you must upload the software utility specified in the beginning of the solution (the one downloaded fron Cisco). After the "address" command, issue an "server" command to put the IP address of the TFTP server. Than, use the command "file example.bin", where the example.bin is the file downloaded from Cisco. Maybe you will need also to specify the gateway of your network. This you can accomplish by using the "gateway" command. Finally, use the "tftp" command to start the download.
The default Telnet password after this process is "cisco."Go into configuration mode and issue the passwd your_password command to change your Telnet password.

Good luck!

Best regards,
T

Not able to telnet to my home router (netgear WGR614V9)


You have to have telnet access enabled for all earlier revisions of wgr614. See : http://www.seattlewireless.net/index.cgi/NetgearWGR614#UnlockingtheTelnetCosole but bear in mind that v9 is not known officially to have a telnet CLI.

I have cisco router 857 and dont know how to configure


Hi!
You can access the user manual for your router by going to:  http://www.cisco.com/en/US/docs/routers/access/800/850/software/configuration/guide/857sg_bk.pdf

But simply put,  - You have to enable the web interface in Hyperterminal/Telnet/Terminal - To connect to your router this way, open your Terminal and type the following commands in order:
1) enable (enter password if necc.) 2.) config term 3.) ip http server (this command might also be set to "no ip http server") 4.) exit
After doing the above: 1.) Press Cntrl+Z 2.) Go to Copy, Run, Start 3.) Open your browser and go to "10.10.10.1"
Good luck! -TJ

Lanier ld122 503 service unavailable


This can occur if the Web services has been turned off in either the Web Image Monitor or from a telnet command for this device.
To check the status of these services you will need to telnet into the device.

1. From a command prompt type : telnet then the IP Address of the device

2. Telnet will respond back with a request for a login and then a password. Enter the login and password. The login and password used for Telnet are the same credentials that are used to log into the device’s Web Image Monitor (WIM).

3. Type in show at the msh> command prompt.
This will output many lines of information. The information you are concerned with is under the TCP/IP-Mode heading. You may need to scroll up in the command prompt window to see these services. The device’s services will be shown followed by their status. The ‘show’ command will show if the services are enabled (UP) or Disabled (Down).

4. If Web shows a down status, at the command prompt msh> type in set web up.

5. At the command prompt msh> type in logout

6. To make your changes Active you must type yes when prompted to "save configuration data"

Note: Always check with your system administrator before making any changes on a network device.
