Protocols / Routing :: Locked Out Of Device On Network
Apr 12, 2012
I had a custom device/computer on my network that was hacked from hong kong. It's one of those things where I seriously think the chinese have built a back door into it when they built it or something because everything was secured and monitored.The device runs it own OS or something like that I guess you could say. It can also run it in standalone mode broadcasting it's own signal. Once I figure this out I may not put it online anymore but thats besides the point right now. When it was hacked I'm pretty sure the port it uses to connect was changed from 80 to 591. When it runs in standalone mode I can connect to it but I am unable to actually access it's proprietary graphic network interface. It sends out UDP every few seconds or so and basically I was trying to search for some type of udp broadcast monitor and have tried using network tools such as netstat, port scanning, multicast, etc on all of the big three OS's because sometimes it seemed to finnicky what it wants to connect to. I've tried to let it connect back to my router again which it seems to do, but is then denied access and I think it may even have a trojan or somethng so I don't want it to that but if I have to to access it again I will.In standalone mode I've it usually trys to connect on 192...5 or 192...7 and I've tried to get through 591, 23, 80 etc. multiple times with no luck.

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.

My wife and I Security Enabled our wireless network several months ago.We recently moved, and after transferring Internet service, we realized we'd lost our passkey.My wife's laptop has, after one failed attempt to connect to the network, refused to even show the network as an available connection.We currently have the router set to broadcast SSID.We have restored factory settings on the router and completely revamped the security setup.We've removed all other networks in the area as optional connections on her computer.We also replaced the ethernet cord to my desktop because the old one started erratically disconnecting.Nothing's worked.My wife's computer is a Dell laptop using Windows Vista.

I just received a blu ray player for Xmas that has an Ethernet connection for streaming Netflix,YouTube, etc. my problem is my router is upstairs and the blu ray is downstairs. I really don't want to run an Ethernet cable from the blu ray to the router. Can I use another router on the same network and have it close to the blu ray?,I have a netgear router just laying around and the main router is a Verizon fios router.

I have a need to use two routers (Each with different ISP) on my (LAN) office network.I presently DO NOT want to go the (Two ISP's on one router, or Load Balancing router). I Just simply want two routers with two separate ISP's.I will assign the managers workstations to the faster ISP, and other Workstation to the slower connection.And it seems to work, and all resources seem to be available on the LAN, regardless of which (Gateway) Router(1 or 2) I point the workstation to.I assume because all devices are on the same LAN 192.168.0.XXX Is this a proper way to allocate and use two routers on the same LAN?

I have a local DSL line in our remote office. We are connecting a microwave antennae that carries our main office internet to the remote office.I want to be able to connect both paths to a Layer 3 switch and route traffic through the main office with the router connected to the DSL as a fail-over solution.I would really like to stick with HP Procurve's if possible.

I'm trying to connect an Xbox 360 to my University's wireless network using a bridged connection between the wireless adapter and the LAN adapter. I can connect to the internet on the Xbox, but not Xbox LIVE. I get an error message stating that my MTU setting must be 1364 or higher. I obviously cannot access the router settings because they are the schools routers and I do not have administrative privileges. So, Is there some other way to modify MTU settings without that access?

I have the modem feeding a router that I turned dhcp off to use it as a switch, I then have the switch feeding a ubiquiti nanostation and a wireless router (to feed house 1). The other end of the nanostation is in house 2 (1000ft away) where I have it feeding into another wireless router to feed that home hard wired and wireless.Everything works but cannot get both to work at same time.

We have two networks in our lan: 10.0.0.0/24 and 192.168.1.0/24. Actually the networks are separated. The 192.168.1.0/24 network contains some hosts that ip can not be changed. We want redesign the network and communicate with both networks without routers. I thougnt about changing the netmask for 192.168.1.0/24 in 192.168.1.0/22 (1022 hosts) and change IP's in the 10.0.0.0/24 network in 192.168.2.0/22.

I was working as IT Support in an encoding company. I support over 500 desktop users. my problem is about in entire network because i always encounter hang network in my grave yard shift. Our network system set up have domain server, antivirus server, database server, 4 PC's use as backup servers and 3 unit of network attached storage and approximately 500 units of desktop use for production in encoding. I always experiencing network hanging then after all system will be freeze, so i suggest to shutdown all pc for usually in 5mins then turn on again. In an hour the problem is still exist again and again. I did all possible way to make the production smooth run for my whole shift but still after some hours it occurs again. I dont know what would be the possible reason why the network hangs and stuck up. The network attached storage did not reach the entire capacity, the antivirus server is still updated, the domain and database server are working properly even the PC's use as backup server. There is no internet connection we use in production, so i assure that no virus we encounter in all pc. Is it the cabling? or is it the switches?

I have Dell machine with Win Xp3 loaded, on my local network (and other computers). I set NIC card "Link Speed & Duplex" to autosense & make direct connection to my modem and works ok.When I plug into the network router I get the 'Cable is unplugged' and no Internet connection.I can change the "Link Speed & Duplex" to 10Mbps/Full Duplex and get intermitten connection. Also when I copy a file from Mapped drive I get "Cannot copy xxx - The specified network name is no longer available".
1. the NIC software is recently updated PRO/100 Adapter NDIS 5.1 driver
2. Although Microsoft has suggested Symantec < ver 4 has had an endpoint problem, I have 10.1.6.6000.
3. TCP/IP Properties are on automatic like the other computers.

Have a problem connecting my new IPcamera Elro C903IP so I can access it through the internet. Did the camera setup according to the manual. Local access (wifi network) works fine but access through internet remains impossible. IP of the camera is still 10.0.0.110 but I found out that for access trough the internet the IP would be like 192.168. etc but I can't change it properly.I have cable internet and a wifi router Netgear WNDR3700v2.Documentation that I found about port forwarding etc is not clear enough to me. I tried over and over but can't get it to work .

The question is apparently simple. A network is given, consisting of
- 1 network core switch: HP 5500-EI (Layer3)
- 4 access switches: HP 5120-EI (Layer2)
They are connected in the shape of a star (the core switch in the center)The task is to measure the occupation rate of this network on a per-VLAN basis.
For example : To be able to generate statistics like: During the last week - Monday to Sunday - the netowork occupation with VLAN 10 traffic was 30% and VLAN 60 traffic was 70%.

We just had a TEW-72GR router fail and replaced it with a TEW-GR. Now I am unable to get to my domain (mydomain.net) from outside the network. Inside the network, all appears to be fine. I can enter that address and get to the site with no issues.We use SBS 2008 with windows 7 clients.All clients can get out to the web, we can send and receive emails, but I can not access the domain.

I have set up port forwarding for my WD Network HDD, which runs a Media Server (Twonky). Now, I have tested the ports and accessed it through the internet and it works fine, until... I click a link to open a folder and suddenly I get a "No such page" error thing. I have however identified this problem, it seems that when I go off the main page it re-routes to the original network address, not my IP forward address. For Example if my IP was 82.9.12.456 and the port was 800 i would go to "82.9.12.456:800" and it would load but once I navigate i go to "192.168.0.*:800/*****" and does not load the page. If i then copy and past my IP into the URL it works, but this is annoying.

I'm studying for a Cisco certification and I'm trying to wrap my head around the routing. I understand how routers work for the most part and how the get updates about networks and how many hops away they are, but I don't get what happens when a router doesn't know the path to a network.

partition the departmental IP network address block to create a staff and a student subnet. Each of these will be identified by its own network address and netmask. It is university policy that you must be economical with the IP addresses. That is, the subnets must be as small as possible, but they must be large enough to accommodate the maximum number of hosts you were given. Also, it is university policy that the respective gateway router to the outside world should always be given the highest possible host IP address in the subnet. The student subnet should have a higher IP network address than the staff subnet. The network must be able to support up to 60 machines on the staff subnet (not counting the router) and up to 120 machines on the student subnet (also not counting the router).
IP address/netmask
University network address127.158.128.0
University network mask255.255.192.0
University internet gateway IP address127.158.191.254
Department network mask255.255.254.0
Department router address127.158.129.254
Suppose that the network address of the departmental network is 127.158.128.0 (calculated by AND between Dep network mask and Dep router address)I know that 60 machines would use 6 bits for the staff subnet.the netmask of staff would be 255.255.255.192.how can I figure out the the IP network address of the staff subnet.I have worked out the range for the staff subnetwork.
127.158.128.0 - 127.158.128.63
127.158.128.1 = Gateway address
127.158.128.63 = Broadcast address
Now how can I calculate the IP network address of the staff subnet?

I am a medical student and I use my college wifi to download torrent files via utorrent. Earlier they have blocked torrent sites, So... I use to download the torrent address via my 3G Dongle and then open it in the utorrent to download the whole file ( 4 GB or 8 GB size). The WiFi provides about 1-2 Mbps speed and the files ude to download very easily . But, now along with the blocked site , ... the utorrent is not catching speed.

I am attempting to replace my actiontec router with the Cisco 871 I have little expirience with CLI-IOS so I was trying to use sdm express that failed to load and when I finally got it to load it still didnt work and I ended up getting locked out of the router it was totally unresponsive. So I did a reset and now am attempting to use the Cisco Configuration Assistant to set up my wan connection but it have been loading security related data for 15 minutes and I have a feeling it's not doing anything at all. I don't understand what I'm doing wrong.... Any advice.... I just was trying to get a default set up that would give me internet access Im not trying to enable any of the security functionality at this point.

How do I do that?E1200 series linksys router. I'm looking for an ethernet cable and my installation disk right now to see if I can connect with the cable and maybe use something on the disk if I have to.

I've been using the trial version of a product called Folder Lock on another computer than the one I'm using right now to type this message. I got a little too enthusiastic about locking away folders into Folder Lock on that other computer, and I think I locked away Folder Lock itself.In the past (before this problem developed), when I clicked a Folder Lock icon, it used to prompt me for the Folder Lock password, which I would then input, and then Folder Lock would open, and I could lock and unlock folders. But the problem is that now I don't get prompted for the Folder Lock password. I get a message (from Folder Lock) that says, roughly, "you may not have permissions to carry out that action." So even though I have the Folder Lock password, I can't open Folder Lock, because it won't prompt me for the password, and just says I don't have permissions.I also locked into Folder Lock my downloads folder on that computer, and apparently folders or icons that used to allow me to access the internet on that computer. I can no longer access internet from that computer.I'm wondering how I can get Folder Lock to prompt me for the password, so I can open Folder Lock. I would like to unlock all the folders I locked -- including if I locked Folder Lock itself! I locked away a lot of my important stuff. I wonder if I should do a system restore to a date before I installed Folder Lock, but I wonder if the system restore might fail to delete Folder Lock, because Folder Lock might prevent its own deletion. I have Folder Lock 7. I have Windows 7.
