Cisco WAN :: C877 Device With Unknown Ip Address
Apr 24, 2013
We had a new linux server installed at a remote office yesterday, unfortunately the guy installing the server forgot to change the IP addresses, doh. It's plugged into a C877 and I can see the port is up/up and I see the mac address using 'sh mac-address-table'. The ip address on the server is unknown but it's unlikely to be in the correct subnet for the vlan it's attached to.
Is there a way I can add an arp entry manually to the router, then ssh to the server and correct the ip address? Or is there some other way to establish the IP address of the server? It's gonna be a pain to revisit the office and there's no one there that can get into the server room to do anything from the console.

Since i got sky broadband it's always been running super slow, the amount of times i have called them is ridiculous. So i have just been looking around on the sky address to see if i can fix it and in my Attached devices i have, the pc, an ipod touch and an unknown device. I'm wondering if this has anything to do with the slow speeds and maybe it's somehow 'stealing' my broadband. I've read a previous post of the same type but that wasnt for sky. i ran the ipconfig/all into CMD

Though ASA5585-X S-20 and UCS C200 are not in LMS 4.0 supported device table, I'm wondering if there is any way to monitor these devices using LMS? Our data centre has a quite number of UCS C200 servers and two ASA5585-X S-20.

My desktop's internet connection is acting up. It's always worked fine, then all of a sudden it has stopped. I can still access MSN messenger and Paltalk, perfectly fine, and it is showing that I have an internet connection. However, when I open any of my browser windows, it cannot access the internet. My laptop and ipod are connecting fine on the wireless. I have my ethernet cable from the desktop plugged into the router, which is plugged into the modem. I CAN force the connection to work by 'talking' to the modem (using the IP address) and doing a disconnect and reconnect. This lasts for a little while, then it stops again. When I do my network map, it shows an 'unknown device' where the modem is supposed to be. When I disconnect and reconnect the modem, it changes from 'unknown device' to 'switch'.

I have a Dell 7720 148285 SE notebook. I use Windows 7 x64 Professional Edition. I downloaded and installed all the latest drivers from Dell Support site. Unfortunatelly I have got a problem.I see an unknown USB device in my Device Manager. (I have not connected any USB device to my computer except one mouse, but this is recognised correctly.)url... recognised that I do not see anywhere my Bluetooth adapter. So I think might be that is the problem.I installed the following drivers:[code[
Of course I restarted the computer every time I installed a driver but the 'Unknown device' still remained url...noticed that if I turned of my wireless connection with the keyboard buttons: Fn + F2, then this Unknown device have been disappear. After I re-enable the wireless connection with Fn+F2 buttons, then I get this error message, and my 'Unknown device' is already show up.How should I install the Bluetooth driver correctly? And which driver should I use for that?

I recently purchased a Linksys EA4500 Dual-Band N900 Router with Gigabit and USB. Everything set up great with no problems and after a day or 2 I managed to get all home devices connected (2 laptops, 2 printers, an iphone, 1 tv, 1 blu-ray, an old desktop, and a tablet). Everything was connected right and working and I installed the Linksys app on my iPhone which let me see what devices were connected and all that. Well, last night, an unknown device showed up as a connected device. It's labeled as: android_(insert string of characters) and has a MAC address. I've tried and tried to identify what this device is and I can't. Everything else on our network is still showing up independently of that device. I'm worried that someone using our connection and possibly putting our device security at risk. What can I do to A) try to identify what the device is and B) if it is an intruder, block it's access.

I have the WRT400N router with the latest firmware. Recently I have noticed a device in my DHCP that I do not recognize. It is not device I own (believe me, I have racked my brain and confirmed) as it shows as an Acer pc. I cannot ping the IP address however. I have rebooted my router several times thinking maybe it's a former connected device but saved in memory but it keeps coming back. I am thinking possibly it is someone hi-jacking my Internet, but not sure. I am using WEP security but it shows a LAN connection which is strange for a wireless device. The only hard wired pc is my HP.

It may be a coincidence but my Broadcom Network Adapter 802.11g stopped working after trying to fix 'unknown device' in Device Manager (It was working perfectly before this).OS: Windows 7 Starter on 'BenQ Joybook Lite U105'.I tried the Windows Network trouble shooter and it didn't work (saying there may be a problem with the driver. I uninstalled the driver and re-installed it (including a possibly newer one) and it didn't work. Within 'Network Connections" the Broadcom wireless adapter is shown as 'disabled' I R-clicked to enable it, a window popped up saying it was enabled but it still showed as being disabled. My feeling is that something is preventing it from being enabled, logically, I would guess. Also went to 'Component Services' and ether started or restarted everything with the word network on it still no luck..My Google search on an other pc , now on day 3, couldn't find anything. (BTW the 'unknown device' which according to the icon, seems to be the joybook itself, is still not fixed and still listed as 'unknown device').

I keep getting some additional IP addresses logging onto my home network that have an address outside what should be allowed by the router. The server is running at 192.168.2.1 and is set to only allow clients from 192.168.2.2 - 192.168.2.10 so a total of 9 clients should be allowed on.The problem is that something keeps logging in with an address of 192.168.169.2 or 3 etc. Sometimes more than one device at a time.I have assumed that it is some automated or virtual client as I'm pretty certain my network has not been breached. I have a 9 character password with a relatively random alphanumeric combination, although I haven't tried changing the password (I live in a share house with with a bunch of devices using wireless, so I haven't yet bothered). What I don't understand is how it has connected with the xx.xx.169.xx range at all. I have a Belkin 'Share' Wireless N Modem Router and at some stage there was a 'guest' network but that has since been disabled and I still am seeing the extra address. I have attached a screen shot of the DHCP client list on the router.The following is a list of devices that may be on the network at times, I'm thinking one of these may be responsible for the problem:
Windows Vista Desktop - Only LAN device
PS3
Macbook
Epson wireless printer
Android HTC Desire Mobile Phone
Laptops running various Windows versions (XP, Vista and 7)
A few thoughts I had:
- the android phone is capable of running a wireless hotspot, may have to look into it to see if if has been operating as an access point into the Belkin router, but assumed this wouldn't bring up clients connected to the phone on the home router.
- The desktop has PS3 Media server installed to stream video to the PS3 over the network (not that I have ever managed to get it to work), however this is not ever open on the desktop.

i have a little 877 router running Version 12.4(24)T2. I want to muck around with an IKEv2 IPSec VPN but i can't find anywhere to configure IKEv2.
I have found some doco that says its under the crypto config, something like router(config)# crypto ike2 ...........
But i don't have that option. Is it anywhere else?

I want to achieve the following setup:
So basically I have a C877 and a Cisco ASA 5505 and I want to push the public IP of the ISP to the outside interface of the ASA so the Cisco 877 will only be responsible for ADSL and PPPoA. Don't ask me why I don' t use a modem/router instead. I know that is a waste to use the C877 in this way but I want to test the setup.
Right now the config of the C877 regarding ADSL and PPPoA looks like that ( I don't have the ASA connected yet, so all the PC are connected directly to the C877 right now):
interface ATM0 no ip address load-interval 30 no atm ilmi-keepalive pvc 0/35 encapsulation aal5mux ppp dialer dialer pool-member 1
interface Dialer1 ip address x.x.x.x 255.255.255.248 ip access-group OUTSIDEACL in ip nat outside ip inspect FWRule out ip virtual-reassembly encapsulation ppp dialer pool 1 ppp authentication chap pap callin ppp chap hostname xxxxxxx ppp chap password 0 xxxxxxx ppp pap sent-username xxxxxx password 0 xxxxxxx
ip route 0.0.0.0 0.0.0.0 dialer 1
ip nat inside source route-map Nat interface Dialer1 overload
interface vlan 100 is my LAN configured with DHCP.
how I should configure the C877 to push the public IP to the ASA?

I'm running a Winsock server on my machine, and I want to be able to connect a client (on an external/remote) network. I know that there are two IP addresses: The WAN IP which is what your IP address looks like while connecting to the internet. There is also an IP address assigned to you by your router. If both machines are on the same network, then I am able to make the client connect to the server by providing the Router-IP. But when they are on different networks, they do not connect even when i give the WAN IP. How exactly do I specify an address for a remote device ?

I'm in need of a device which can switch to several items which has the same mac address. I heard that there may be devices that can handle this, by for example mapping fake unique mac addresses in the switch to each on of the same mac addresses on the devices, so when you try to send something to a "device with the same mac address" you send it to the faked address in the switch and the switch just forwards it.

we manufacture an industrial device that runs embedded linux, and we are throwing ideas around on how we can find devices that are connected to our network, without knowing their ipAddress. I know this is possible, because Advantech do it with their ADAM utility to find units. I put a WireShark sniff on my LAN as the ADAM Utility found a unit, and saw the following[CODE]

I just got the motorola droid 3, my first android device. I'm trying to figure out how to get my device to connect to my network as it won't obtain the IP address.I have a Motorola Surfboard SBV5120 Modem and a Microsoft MN-700 router. I just switched from the Palm Pre Plus which connected perfectly to this network, the network is unsecured and has 2 pc's and a 360 running on it. I was able to connect to my friend's wireless network fine at his house.

I'm trying to get started on setting up my first Transparent ASA.I understand an ASA in Transparent Mode can now have an ip address with Bridge Groups or some such mechanism. I'm looking for examples of how to set that up and other information below. Is the ip address associated with the device or is it interface specific? Will I be able to SSH with that ip address setup? Can I use ASDM if the Transparent ASA has an ip address? This 5512X has an IPS. Any one who has setup an IPS on this platform knows it has some very particular requirments in order to communicate with the outside world. I need examples of how to do that with a Transparent ASA.How is NAT setup differently (if at all) on a Transparent ASA?Are ACLs done any differently?

Okay so currently in my possession is a SR 5500 wireless channel receiver with a problem.. We need to find its current ip address it also is not a standard ip address such as 192.168.xxx.xxx it has a standard ethernet port and of course GPIB ports
I'm looking to know if there is a way I can find its ip address by maybe with a crossover cable, or by bridging its connection to my computer and somehow seeing what ip it's requesting.

When ever I create a network object in ASDM 6.0(3) the UI also wants to send the command 'asdm location (network object IP address)' to the device.What is the purpose of 'asdm locaction ....'? Is it telling the ASA-5540 that the IP address is allowed to connect to the device using ASDM?If that is the case why does 'asdm location xxx.xxx.xxx.xxx'get denerated for every network object I create?

We have a daisy-chain like network at my work involving various cobbled together parts such as Print Servers and switches. Today a random computer has appeared on our network with the name USER-U40PVRNHWL. We do broadcast a wireless signal, but it is password protected. I have done a complete sweep of the building and there are no extra pieces of hardware physically connected into our network.
