Asa 5505 Reset

[Demeter Exekutor]

4The current configuration register should be the default of 0x01 (it will actually display as 0x00000001). The security appliance will ask if you want to make changes to the configuration register. Answer no when prompted.

11. While still in Configuration Mode, reset the configuration register to the default of 0x01 to force the security appliance to read its startup configuration on boot: asa(config)#config-register 0x01

A factory reset (configure factory-default) from the console will reset just the config and not erase the added license keys, correct? I don't have access to the original keys (they were installed by the previous owner) and don't want to lose access to these extra features.

I can confirm that the Cisco ASA 5505 indeed does not lose the activation key/license when performing the factory reset. No action is required after the factory reset - it boots back up with the key intact.

I have an ASA firewall setup, but i have forgot the enable password; I have the admin password anyway.

I am not trying to reset password using rommon; Please dont suggest confreg break

I saw an user named enable_15 in ASDM, but resetting this password also did not work.

If your admin credentials work as the enable password...then that would be the encrypted enable password you are seeing right? enable_15 is always listed in users - its like the built in Administrator account in windows.

I always like to make sure the running configuration is saved to non-volatile flash memory in case the ASA 5505 loses power. The way to ensure the unit will come back up correctly in the event of a power failure is to reboot it!

show version and then look for licence. Mine says base license, you can also look at vpn users and such as that is the part you are upgrading for primarily.10 total vpn users on base license. 50 for upgraded, or unlimited for premium package.

i did the same procedure on cisco asa 5510 series but when i reloaded after a reboot no configuration was found in running configuration even i copied startup-config to running-config but still when i reboot it the running-config is somehow erased or removed

could you please tell me about this

hello, my apologies, im a newbie too and as most of the people around here, out network admin is no longer with the company and left me nothing. i have an asa 5505 and recently we changed the company IP and i needed to set that up in the router but i couldnt login. so i decided to do a factory restore and start from a clean slate. i was able to do it and it was giving me an ip but i needed to remove the password and i reset it again to factory and now i am not getting any ip address at all. its giving me a 169.254.60.195 ip address. need your expertise.

thanks for the quick response, i did try to reset it again for about 3 or 4 times now and being careful to follow the instructions carefully. on my initial reset it did work and i was getting an ip address 192. but i couldnt log in to asdm so i reset the password and did another factory reset again but now im only getting a 169 ip and port zero is plugged in to our network but when i plug in my pc to port 1-5, i do not get any led lights only on 6 and 7 but still not giving me any address. i cant connect using asdm nor and i have tried resetting it numerous times and nothing.

my cable is straight through and i can connect to the network directly. and we are running dhcp. our ip is at 10.0.0.x range. i have tried unplugging the uplink and just use one cable to connect the device, there are no link lights form 0-5 only 6-7 and it will still give me 169 ip. i tried pushing the reset button at the back but it seems useless. i can still connect to the device using the console but no asdm or https. any ideas? thanks

Have your lawyer write them a letter threatening legal action if they do not hand over the passwords. Make sure to be clear that if recalcitrant IT company causes any interruptions in productivity that they will be sued for those damages.

I have tried to reset the ASA 5505 that i have, i have followed all the advice, but i am getting no where, the device i have was set up quite some time ago and left, the guy has left the ocmpany with the settings for the device.

When i try a hyperterminal session with the device, i get nothing, i cant even get the device Command line when i press enter a few times, i know the session is there as when i power off and on again, i get the:

cisco systems page that tells me the BIOS version, and at the bottom the ROMMON version, but i cant get an further on with the reset to factory default?????

Any help anyone.

Thanks for your very helpful information. I have one question. I would like to reset using the factory-default but I need to set the Management IP address to one on my existing network. At the same time since it will be plugged into an existing network with a working DHCP, I need to disable the dhcp and just give the management interface a static IP that I can hit over the network. Is that possible or should I just try to set it up using the ASDM and my laptop?

PS I am about to change over from an existing Windows Server 2003 ISA 2006 firewall to my new Cisco ASA 5510 firewall. Any suggestions or hints for making it as painless as possible. Thanks so much for your help.

Sonicwall are so much easier to use and have a faster throughput when compared to similar Cisco device and much cheaper, i though when i finally got into the ASDM and configured the ASA i was thinking these cisco devices are so bad after all but for a device to not save its own config, whats that about?

I have followed the instructions to reset to factory settings. Completed and believe everything worked. But my computer does not get any ip adderss to conect to. So, I redid the reset many times and get the same result. I have noticed that there is a Error in the executing command lines. It says:

Failed to apply IP address to interface Vlan2, as the network overlaps with interface Vlan1. Two interfaces cannot be in the same subnet.

On a site-to-site VPN using a ASA 5520 and 5540, respectively, I noticed that from time to time traffic doesn't pass any more, sometimes just there's even missing traffic just for one specific traffic selection / ACL while other traffic over the same VPN is running. It happens even though there's a constant ping running. The reason might be that it runs over a satellite link which isn't perfectly stable.

You can do it on your side, entering the remote IP. Or login to the remote site, but possibly you have to do it outside the VPN, so using a different interface, for example using the public IP instead of the IP to which you connect through the tunnel.

Also in regard to Stefan's answer, if you do a clear on a remote device over the VPN you're resetting, typically it will re-establish the VPN and your SSH session will continue per normal instantaneously or at most within seconds. I do it quite often on ISR G1 and G2 routers all the time when modifying their tunnels.

I needed a more reliable VPN solution to a remote site I need to work on every now and then. At the time I had setup the remote sites router to push VPN connections through to the Windows 2003 Server (I know, I know) and it would handle the VPN connection. From there I'd RDP to other desktops as needed. Now, when the server would crash and be M.I.A. for whatever reason, I'd be without a VPN connection and would then have to drive to the site to do anything.

Long story short, I came across an ASA 5505 and saw the words VPN associated with it and now I'm setting one up to basically be a VPN point at the remote site, can then hit other desktops from the edge of the network rather than rely on the server to be available for the WHOLE network to be available.

If you have forgotten the password to access your ASA configuration or need to perform maintenance on an ASA device but do not have administrative access, this process will guide you through the steps that are necessary to recover the password to administer it. You must be physically connected to the device for this method to work. In my case, I am directly consoled to the device through a serial cable connection and using PuTTY to reach into the device itself.

You will see the current configuration register (normally 0x00000001) and will be prompted to to change its value. Be sure to make note of the register value so you can change it back later, when you are finished making changes.

The ASA should boot up normally now and you should be able to go about your business without any further complications. Let me know if you know of any easier or better ways of resetting passwords for ASA devices.

The 5505E is a weatherproof measuring wheel with a long battery life. It can be set to measure in either metric or imperial units at the touch of a button. The 5505E adds when moving forward and subtracts in reverse. It has an electronic brake and telescopic handle that folds down for easy transport. Two measuring modes are available: trip and total.

Check in Event Viewer for any Critical, Error or warning events that may be logged at the same time that the laptop crashes. To get to Event Viewer in Win 10, press the Win Key + x key (both together) and then click on the link.

Yeah, both fans work perfectly, I have no overheating problems, when I check the Event Viewer it shows some Error Code 28 and some other related errors, also, when I checked the Device Manager, I found something about Logitech but every time I uninstall it and reupdate the device, the same problems come back. I even reset the computer for factory reset and still have the same problem.

Also did you check event viewer? You seem to be talking about error codes in device manager. With event viewer problems are listed under the categories Critical, error and warning and then show source and event ID number for the event
