Cisco Switching/Routing :: Password Break In ASA 5510
Jul 24, 2012
I have Cisco ASA 5510 series router which was handling by our one of our network admin who left without giving admin password. Now this is time to break the password . Since i don't know the admin password of the router , i don't how to handle few request. I am not a basically network admin guy to handle such things but i need to know how to break the password in order to do further requests. How to login router admin console without password or any chance to bring into default factory configuration.?
I have a 3845-Mb that has a username and password already on it. This needs to be wiped as its a sold unit. However i cannot break into teh IOS in Hyperterminal using Ctrl-Break either as it boots or after teh IOS image has loaded (after it shows Decompressed image {ok} etc). I have tried several break key combinations such as ctrl+F6+break and they dont work either. On boot the unit does show Password recovery Functionality is disabled. IOS image is 12.4(13r)T.
i have cisco 1941 router.unfortunately i dont remember password.Can any body tell me how to break password.I tried to go in Rom mon using ctr+break but nothing is happened.
Since last week we started noticing this problem that the branch users started to complain of slow application response.. After verifying it with the ISP and middle network we noticed that if i ping from my machine (ie usernetwork) to the WAN Router interface (facing the ASA) , i get time outs.. which is strange cause this is directly connected to it via ethernet cable.
Switch: WS-C3750X-48P (Stack with 2 Members) IOS: 12.2(58)SE2 Lic: IPBASEK9
[Code]....
Since i added another Member to the Stack, i'm facing the following problem: When i login with my tacacs user account, i will not be asked for the password. The same thing is for the tacacs account of my colleague, after entering the username he is logged in. It seems for me, that the passwords are cached only for this Switch.
I have an ASA 5510, with Ethernet0 connected to Internet via a T1 line, Ethernet1 connected to LAN1, and Ethernet2 connected to LAN2. LAN1 & LAN2 are independant, but share the Internet connection, via the T1 line. On LAN2, I have another router that connects to the Internet, via a Comcast line. I wish to route some of the traffic on LAN2 (10.38.77.0) to the other Router, on LAN2 (10.38.77.12) (connected to the Comcast line). I have entered the following lines:
I have mobile users using air cards that connect to the network with a VPN product called Net Motion. Our firewall is a ASA 5510. Once connected to the Net Motion VPN server the user will get a DHCP address from our network. In the past we could not get the VPN tunnel to complete since our layer 3 switch (3750G IP services) has 3 egress points and the egress point that we needed the VPN traffic to go out of is not the default gateway. To solve this we had the air card carrier set switch our air cards to static IP addresses and using route statements for the public IP addresses and access lists we got it to work.
The problem with this is that every new air card we provision needs a static IP address. My question is would policy based routing work in this scenario? The problem has been that the VPN tunnel was not able to complete the negotitaion phase as the traffic came into the switch and was trying to go out the default gateway. The VPN client wont get an internal IP address until the VPN tunnel is created.
I would like to get away from using static IP addresses.
I have an environment where i have two nexus 7010 switches, along with 2 nexus 5510's. I need to run OSPF as a layer 3 routing protocol between the vpc peer links. I have 1 link being used as a keep alive link, and 3 other links being used as a VpC link.
1) Is it best to configure a separate Vpc VLAN i.e 1010
2) Is it best to configure a vrf context keep-alive
3) just have the management address as the peer ip's.
I have Cisco ME3400 series switch .Unable to login as i have no user name and password. I want to set the swirch to factory default but not found any nub to press.
I'm been telnetting onto a 2955 and then upgraded the IOS and enabled ssh version 2 and then issues a "write", when I came back the exec-timeout had been issued and I was logged out of the router and now it is asking for a username and password and not just a password liek it did before enabling ssh. I havent yet put a username and password on yet, just the telnet.What would the username be if I havent set one?
I am trying to use the password recovery for an NME-16 and am having trouble. I am unable to look at my files in dir to so I can rename them. I can get the switch to bypass the config and come with the switch: prompt, but can not do anything more. I am trying the password recovery guide, but cant get to the text file to rename. I am using a 2811 router.
I have tried pressing the Reset button (within 5 secs) when the router power up. On my HyperTerminal, the image was loaded and the line interfaces were up. But when I press enter on HyperTerminal, there was no response.
I recently decomissioned an 871 from a small business site and the owner did not want the device anymore. So now I'm trying to use it back at the office in the sandbox, however I don't know the password to the device and neither does the business owner. There's a reset button on the back, but from what I've read (here), it only loads a different config file found on the internal flash. Tried this, no dice. Is this essentially a bricked router now or is there anything else I can do to clear the config and repurpose it for my use?
I trying to do password reset on a 506e that I got with the current password unknown. I've gone to the Cisco URL for the reset: [code]
I am using the correct bin file as I checked with my pix version. Also I CANNOT ping the firewall from a PCor system on the network, but CAN ping everthing from the PIX.I've tried using interface 1 but no go. Also I've checked the TFTP software (Solarwinds) is running fine and I've unblocked it in XP's firewall.
I have a cisco 2960 switch. Trying to recover a password. Have tried several different ways to recover it. I have let the switch load completely, then pressing the mode button waiting for the light to turn amber and then green. I also have held the mode button down, plugged the switch back in until the mode light turns from amber to green. Either way I will type flash_init. Then when I type load_helper I get a invalid command response. The command load_helper isn't even listed.
We have installed a SRST in one of our remote offices. They have ISDN Primary, and we have a 6mb MPLS link to our main HQ with 400k of QoS on the line. During the day, both Internal calls over the MPLS and external calls over the ISDN break up, but it doesnt happen all the time, i.e in a day the morning will be ok, then the users experience the break ups in the afternoon, then its everything is ok again.
The only factor that the calls share is the Lan infrastructure i.e the 3750G switches (7) of them which are stacked.We did have MAC flapping errors, and our telecoms provider suggested that it maybe these causing the issues, however we have got rid of all MAC flap errors, and are still receiving voice break ups.
Because the Lan switches are the only "item" both calls share, I am wondering now if the setup of the switches is correct. [code]
I have over 20 units doing the same thing and it seems to be a software isssue but i dont see any bugs or posts on it. This is only on 2960S switches and not 2960 or 2960G units.
If i use the password reset feature to break the units into rom and then type "boot" instead of power cycling the unit, they will fail MBIST post tests. If the unit is power cycled or left to boot normally on its own, there is no issues and all post tests pass. I know MBIST is Memory Built In Self Test and was thinking maybe breaking the unit into rom disrupts those memory tests for some reason. I tried the following software and got the same results with all of the images:
122-55.SE2 122-55.SE 122-53.SE2 122-53.SE1
Logs attached are from the same switch, one with password reset procedure used and while left to boot on its own.
I can see the console on the router. (Using the USB console connected to a Macintosh.) I was configuring the router though this console connection, and I created a new user (priv level 15) and removed the default 'cisco' user. So I'm stuck at the username/password login prompt now.
I decided to do the password recovery procedure (via the cisco doc I found etc), but I cannot break into ROMMON during the boot process. I'm not sure if that's because my Mac isn't sending the break, or what.
The pw recovery doc says you can "remove flash" if you can't break into the boot sequence. However, I cannot find any instructions on how to remove the flash. I've opened the router, and I see one very small daughter card on the main board that I think is the flash, but I'm not about to start arbitrarly prying parts off.
I have recently aquired a Cisco SGE2000 switch and the first thing I did was update to the latest firmware and change password. Now I cant login? Neither my admin / admin dosent work nor the new user I have created. Is there any characters that this dosesnt support like backslashes or forward slashes for password? If not then what can I do to get access to the switch again?
i just wanna know if it's possible to perform a router password recovery using the reload command and then issue the break sequence instead of doing an off/on on the power switch. i often find in the docs to use the latter.also, is there a way to retain the startup-config on a router when we re-enable the password recovery functionality (no service password-recovery). i've just tried this on one of our 877 and when i hit the break sequence, it went back to factory default setting.
I understand that the password has to be changed the first time we login to Cisco 3945 router but i failed to do that and its not allowing me to connect using default username/password.
I have one CISCO 6509 Switch in my store. I tired to login in that switch but couldnt.. Once it's booted it's asking me: rd: . Find the attachment. I recover the password by changing confreg value but that also failed.
I need to break into a 2901 router to recover the passwords. Cisco's methodology for password recovery on 2900 seriews routerssays to remove the compact flash card and reboot into RMON. There is no external compact flash card on a 2901. Is there acompact flash card inside the box? Or can you use the older method of rebooting and then hitting ctl+break to boot into RMON?
I recently configured a cisco 3750 switch for a stand alone network here at work, and on all our other switches and routers we use ACS to access everything. This switch being a stand alone I dont have that option.
So being like that I have to create everyone in the shop a username and password. Is there a way to prompt the user to change their password on their first login like you would with windows or such?
I recently received a Cisco 3548 XL Switch, I'm trying to reset the password from the console. I've followed the steps but when I type from here: [code]
