Scanning An External Network Through UDP / ARP Scan?

Jun 24, 2011

the setup is as follow: I have two separate network.192.168.90.xx and 10.10.xx.xx the two boxes being connected via an ethernet cable. How would I go about having a 192.(...) machine speak to a 10.(...) box? My boss tells me that via a UDP call the 192.(...) machine can get the IP of a 10.(...) box. Isn't UDP dependant on a subnet mask to limit the # of queries, and in that case would it even be feasable? I was thinking instead of spoofing the 192.(...) IP to an unoccupied 10.(...) IP. Of course to do this would require knowing what IPs are unoccupied on the other network, and I cannot assume the would respond to pings.

Scanning Open Ports On Network

Jan 24, 2012

My company deals in a video conference software which requires certain ports to be open to work correctly, including tcp and udp ports. Clients who want to test / purchase have different kind of network setup. I usually tell them to open those ports require by the software on their end. How do i ensure if the port range required by my software is open once I am at their location. I have installed a few network scan tools but not sure what ip do i scan. Should I scan my server's ip once I am at their location and connected ? or should I scan their gateway ?

Refine Nmap Scan For MPLS Network?

Aug 10, 2011

I am trying to use Nmap to determine whether a certain IP address is available or not. However, the output of the scan shows that it scanned the subnet my computer is on and only one address in the network I typed in (MPLS network). Is there any way I can have Nmap only scan that one subnet and not all the others?

What Tools Are Available To Scan Network And Give More Information About Stranger's PC

Sep 12, 2011

I'm running Windows 7 Pro. I noticed tonight when I clicked on Network in Windows Explorer that in addition to my home PCs there is a PC with someone's name on it. My suspicion is that my wireless ISP has screwed up in some way. I ran SoftPerfect's Network Scanner and don't see any strange IP addresses, so this stranger's PC is not on my subnet. What tools are available to scan my network and give me more info about the stranger's PC?

Network Scan To Discover Rouge Apple Device Host Names

Sep 27, 2011

Anyway, I am looking for a way to discover host names of Apple devices (namely iPods and iPhones) that are on our network. I've tried a number of programs like Nmap, Advanced IP Scanner, and LanSpy to name a few. All of them will report back the MAC address with no problem but no dice on resolving the host name.

My goal is to use the host name to identify the device, and ultimately the person with the device. Any thoughts on how I can go about this? Is there a setting in Nmap I'm missing or perhaps a better program to use?

Nov 3, 2012

I have an Canon MP 530 that works great for my home office network, but right now it's being shared off one of my PCs. I would like to network it like my HP LaserJet P2055dn, but not just printing, also fax and scan (via Adobe Acrobat Pro). Does this product really exist.

About two years ago I bought a Linksys device that turned out to be a $100 mistake, but now I'm really needing this sharing functionality.

D-Link DIR-825 :: 5 Ghz Enabled Doesn't Show Up When Scanning?

Dec 15, 2010

I am running a DIR-825 I believe one of the original's no updates or anything.  I run it mixed mode.  The 2.4 shows up and I can connect to but the 5 ghz (n) speed says it's enabled but I can never see it when I scan on any of my wireless n products (laptops and other computers).  Dlink support told me to change to mixed mode g and n.  I was running it in mixed mode (a, g and n).  D link told me to change to mixed mode g and n and to make sure they stay on channel 6 and 11.  Is this correct.  Which firmware should I upgrade to and is there any easy way to do this?

Cisco Firewall :: 65535 ASA - Port Scanning Protection Through Embryonic Limit Setup

Jul 1, 2011

url...I discovered that it would be possible to be protected from portscan, i mean when someone scan our nework/host from outside, the attacker will see all the 65535 ports as "open" (in that way it will be more difficult for an attacker to perform customized attacks...)So I have follow the setup in that link: policy-map global_policy class class-defaults set connection embryonic-conn-max 15 per-client-embryonic-max 3 service-policy global_policy global . The problem is that I don't have the exepected result..If i do a portscan over Internet from an external host to my hosts the portscan is successfully working and I can view my open ports...I have also tried to set this through a "match" in an access-list but without any sucess.

External HDD Access Over Network?

Mar 28, 2011

Is there any way that I can connect my External USB HDD to my wireless network so that any computer on my network can retrieve files on the HDD.

I previously had a Cable router, which had a USB port on the back so I was able to do this.

But as of next week I am moving back to BT, so i will need to change my router to an ADSL version.

External HDD To Wireless Network To USB Port On TV?

Jul 15, 2011

Basically, I need my external hard drive connected to my wireless network so I can have access to it from two computers BUT I want to be able to stream my videos/music via a USB 2.0 wire directly to my TV.The problem with this configuration is that the hard drive has one input/output USB 2.0 port. I am going to hook it up to a network enclosure which will solve the having the hard drive to wireless network...but how can I stream data via a USB cable to my TV?A friend of mine told me that I can have a USB connection from my desktop going to the TV - this will achieve the data going from my external hard drive via the network to my desktop and from my desktop to my TV via USBDoes this sound like I am on the right track? I am unsure as to whether I will need any software solutions to be able to have access to the data on the hard drive from my TV.

Can't Connect To External IP From Just One Computer On Network

Feb 7, 2013

From our Exchange server, I am completely unable to communicate with one of our partner's mail server. I cannot ping it by either the host name or IP address. Trace route times out at the final hop. The firewall is disabled, and antivirus (ESET) is temporarily disabled. I cannot access the IP through the web browser either, everything times out.However, every other computer on our network can connect fine. I haven't seen any other problems with any other IP addresses, it seems to be only this one that I can't connect to, and only from our Exchange server. All computers are going through the same gateway, using the same internet connection, and using the same DNS servers.The computer that I'm having the problem on is a static IP. All settings look correct, and match another server that I can access the IP from.I've checked the hosts file for anything, and it is in it's default state.

LAN Not Working After AVG Scan?

Jan 29, 2012

OK- so my computer was going haywire - freezing, lagging, crashing. Only thing I could do was to restart in safe mode and run a full AVG scan which did show viruses that were sent to virus vault. Once I restarted into normal windows mode, the computer seems to be working fine with no freezing, etc.....but my LAN connection won't work. Looking at all the device managers and info on the LAN - it says "device is working properly". I have tried downloading a few "fix it" programs like Winsockxpfix and Complete Internet Repair - didn't work.

Netgear WNR2000v2 / Using External HD For Backup On Network?

Aug 13, 2011

Two desktop computers with windows 7 home premium.Router: Netgear WNR2000v2 (which is NOT IPv6 compliant).External HD: 2TB Fantom.I have the external HD connected to one of the desktops via USB. I'd like to use it to back up the second computer to this HD.How do I get the second computer to recognize this as a backup target?Incidentally I've had problems getting HomeGroup setup since IPv6 is required for HomeGroup. I assume the problems are because the router isn't IPv6 compliant. I've tried the Microsoft Fixit 50410 (Use IPv4 instead of IPv6 in prefix policies. I've also reverted using Microsoft Fixit 50440 (Enable IPv6).

Osx 10.5 How Do I Automatically Share External USB Drives Over Network

Jul 21, 2013

I used to have an old G5 tower running OS X 10.5 (Leopard) which I was using as a file server. In this tower I had a USB dock connected where I could plug in 2.5 inch drives from my archive and then access them over the network by connecting to the G5.

Last week I upgraded my "fileserver" and I am running OS X Mountain Lion Server on a regular Mac Pro tower. When I connect to my new fileserver via Finder I am only able to see the local hard drives but none of the external ones. I can add a share-point for the external drives but that is not very practical since I am always connecting different drives from the archive.

So what I would like to have is that when I plug in an external drive to my file server it shows up in the network shares without me having to create a share-point for every different drive I connect.

Cisco :: Connecting Back To Network Through External Interface?

Mar 4, 2013

I have a ASA 5505 configured with three VLANs: Inside, Outside, and DMZ.I am running an exchange server on the Inside network and have configured NAT to allow connections to it from outside. This works fine. I can also happily connect to it using it's internal address from the inside. In the DMZ I have setup a linksys router to work as a guest wifi network. I configured the ASA to block any traffic from the DMZ to the internal network.This has been working fine for the last few weeks.Wireless users cannot access any internal resoureces, but can browse the internet etc.. etc..

My problem is that I want users to be able to connect to the wireless with smartphones, tablets etc..., if they do so, they can access the internet, but not get their email. From my (limited) understanding, the problem is that the ip address I am trying to connect to is the same ip that I am transmitting from. Is there any way to send the packets to the outside network and then loop them back to the exchange server?
