Cisco 1841 Password Recovery
My company installed our two 1841's about a decade ago and we are trying to upgrade them to new systems. The problem is that the tech that did the installation originally is no longer with us and did not leave us all the passwords we need.
I am able to access the SDM and view some of the information there but I need to have telnet access to the device. Viewing the configuration I am able to find out the username that was used and see an encrypted version of the password. It was set up with secret 5 which I have come to understand uses a SALTed MD5 hash.
I need to figure out what this password is so that I can telnet into our device. I can provide any verification information that is needed including the encrypted password (I didn't post it because I understand this is a public forum) if you can help me recover this password.
Thank you.

I observed two cisco 3945 routers lose IOS during password recovery. Router was rebooted, break sequence ctrl-break, then boot(instead of reset) issued. The router booted to its existing configuration or password recovery failed and router was power cycled again then ctrl-break issued. However this time the IOS was gone and all flash file systems were blank! It happened on two routers. Anyone know why such an anomaly would occur or has anyone witnessed such?
config register was set to confreg 0X2142 first time password recovery was attempted. It took but only after the power cycle(not when I simply typed boot) but by then the IOS images were gone. I found that very disturbing when it happened on two different routers and I never saw such a thing happen to a router before.

After swapping hard disks between two servers I can not access CRS Administration page through LDAP authentication. Default username/password Administrator ciscocisco doesnt help.
This guide doesnt help either
http://www.ciscosystems.com/en/US/products/sw/custcosw/ps1846/products_tech_note09186a00805a7acc.shtml
I can not find files mentioned in it. Not sure about our version, I am new to Cisco Contact Services. All I know is that it was configured with LDAP authentication.
Any suggestions?
Thank you in advanceHello. I have the similar issue. We use CUCM 7.1, UCCX 7.0.
An access to CUCM is configured through LDAP authentication. One of the corporate domain was broken, then it was recreated. After that I can't get an access to UCCX with admin user. It's interesting that I can see this user under the users list in CUCM and I can access UCCX with another user (with limitied rights). It seems like ldap integration is still working but something wrong with admin user. We tryed change a password for that user but it didn't help. I tryed use the "FRESH_INSTALL" procedure which is described in this post but when I try to log on with default user I have a blank page under this address:
http://UCCX_ip_address/appadmin/j_security_check.
Could anyone tell me what could it be? How can I log in with default username?
Thanks in advance.

I need to reset the admin password for Cisco Works. I've followed the online documentation and the different methods posted do not seem to work.
The first method I saw was to edit the cwpass file located at C:\Program Files\CSCOpx\lib\classpath\com\cisco\nm\cmf\servlet\cwpass and change the admin password back to the default.
You have to stop the Daemon, change the password back to defualt admin:0DPiKuNIrrVmD8IUCuw1hQxNqZc=::::F:: then restart the daemon.
After doing that I go to the url to access cisco works http://servername:1741/login.html where "servername" is the name of the server.
The new logon does not work.
I then found another doc that said to use the resetpasswd.exe file to reset the admin password. So. I stop the daemon, run the resetpasswd by issuing the command "resetpasswd admin". It prompts you to enter the new password twice. Then restart the daemon. I've checked the cwpass file and verified that the hash for the admin password changes when I reset it. But, I still can not logon.
Is there something else that needs to be restarted?You are probably still using external authentication. Try reverting to local mode first:
1. Stop daemons.
2. Go to NMSROOT\CSCOpx\bin\ in DOS.
3. Issue: perl ResetLoginModule.pl.
4. Restart daemons.
If you still cannot login, the original password file is located under NMSROOT\lib\classpath\com\cisco\nm\cmf\servlet\orig\. Try copying this one to the active file location: NMSROOT\lib\classpath\com\cisco\nm\cmf\servlet and then restarting daemons. -
Cisco ISE 1.2 vm cli admin password recovery
I'm having trouble getting this to work. I was under the impression by mounting the ISO (connect at power on) i could perform the password recovery like it states for the hardware appliance. However, if i mount the 1.2.0.899 iso image (connect at power) I don't seen to get any options in my vm console? At most, I have a <enter> at the very beginning that will take me to Grub or ADE boot menu... but I don't see anything about options to change the password?
Make sure you are following the steps in the following link:
http://www.cisco.com/c/en/us/td/docs/security/ise/1-2/installation_guide/ise_ig/ise_postins.html#38674
Also, make sure that the VM Guest is set to boot from DVD/CD first before trying the HDD.

Cisco NCS admin password recovery.
Hi All
In Cisco NCS shell I have incorrectly entered the following command in order to chang ethe admin password and saved it
username admin password hash <password> role admin
and hence lost the access to shell (ssh). Is there a way to retrieve or reset the admin password. Tried to log in as single user (as in any ohter Red Hat Distribution) but didn't work. In the worst case scenario I have rebuild the server (VM) from the .ova imange, however the licenses won't work.
Any advise would be greatly appreciated.
RegardsHello,
The only way to recover the admin password for NCS would be to use the recovery image (iso). The recovery image is not available for download from CCO. Please open a TAC case & they can special publish the image for you.
For the CLI admin password, the recovery method is the same as the physical appliance. Attach the recovery ISO, and reboot the machine. You may have to force the virtual machine to boot from the cd drive. Once it does, you will get the menu that contains the password recovery option.
Hope this helps.

Password Recovery Cisco WLAN Controllers
Hi,
I would like to know the procedure for recoering passwords on Cisco 2000/ 4000 series contorllers.
Please Help!
Thanks and Regards,
MohanSorry, you have to reset to factory defaults. Then reconfigure. Here's the TAC Case
Solution # K52826052
Title How to recover a password on the Cisco Wireless LAN Controller
Core Issue
Resolution
There is no password recovery option on the Wireless LAN Controller (WLC). You need to set the WLC to factory defaults and reconfigure it.
In order to set the WLC to factory defaults, power cycle the WLC, press ESC Key during the boot up process from the console and select last option(5) to clear the configuration and reboot the Wireless Lan Controller.
Note:The new default username and password is "admin". -
Cisco ACS 4.x Password Recovery
I inherited a ACS server, but I don't have the admin password. Does anyone know of a password recovery technique ?
If it is running acs ver 4.0 on windows, then it is not possible. With ACS v4.0 all the configurations have been shifted from registry to a database file thus increasing the security in ACS. So as of now there is no way to recover the lost Admin password in ACS v4.0, cause no setting is in registry, all settings are in SQL database.
So need to reimage it ...
If it is acs windows 3.3.4 or below then you need to make registry change,
login to ACS machine as administrator..
Go to start ===> run ===> regedit
Click on HKEYLOCAL machine ===> software ===> cisco
===>CiscoAAAv3.2===>CSAdmin===> and delete all administrative users defined by
right clicking into the administraor folder.
Now login locally to ACS and it should not prompt you for password.
For a best practice make sure that you have Allow automatic login is checked
This will not prompt you for password if you are logging in locally from ACS mahcine.
If it is appliance then you need to use recovery cd to reset admin password.

~JG

Thanks for help!I usually suffer from the same issue, but what works for me everytime is the other method that simulates break sequence. Can't find the documentation for it but this is how it goes:
Set the serial connection as follows in Putty:
Baud rate 1200
1 stop bit
8 data bits
no parity
no flow control
Turn off your router, then turn it back on and immediately press the spacebar for about 10-15 seconds. All you'll see is giberish. After that reset your console connection settings to the usual 9600 baud rate, and you'll find yourself in rommon mode. -
Creating "A" record in Cisco 1841
Hello All,
We are using Cisco 1841 router. Our requirement is to configure "A" record in the router i.e. we wanted this router to act as a Primary DNS server.
I can bit explain the scenario.
We have connected Internet Lease line ILL to this router with a static ip assigned to it. We have a domain name registered say e.g. www.xyz.com at www.namecheap.com. We wanted to host the web server inside our office network for our website. We did the necessary changes at www.namecheap.com to the domain www.xyz.com pointing it to our static ip. But we are not able to ping or browse the domain www.xyz.com and we contacted www.namecheap.com technical support and they informed us that we need to create a "A" record where ever the web server is hosted.
I tried to search the internet and i couldn't able to find the necessary online resources for creating "A" record in the router for the domain name. But i could find the below link for creating soa record http://blog.ipspace.net/2006/09/use-your-cisco-router-as-primary-dns.html and created a namesever entries like ns1.xyz.com
But this doesn't create "A" record
Any assistance would be really helpful.
Thanks
SundarDear Daniele,
Thanks for your reply.
You solution worked great for me.
We are able to ping the domain name.
Now we are facing another problem in reaching our web server. I will explain it below.
1. When i type the domain name in the browser we are getting a authentication popup asking for username & password, the popup says "a username and password are being requested by says level_15_access ..."
2. I provided the router username & password it redirect to the following link http://www.sitename.com/archive/flash:home/html/home_aux.shtml. and load the SDM (Cisco router and security device manager) page.
NOTE: we have installed Cisco SDM.
What i wanted is, the site should reach our website hosted in our IIS server inside the network. The IIS server has an local IP address 192.168.1.x and the router gateway has a IP address 192.168.1.y
Any assistance would be really helpful.
Thanks
