WEP Cracking - Packets That Appeared Are Encrypted
Mar 13, 2012
How WEP cracking works. I have a much better understanding now but it seems whatever programs I download and however close I get I always hit a wall somewhere. I am using windows 7 64 bit and my network adapters/cards are Broadcom 802.11n Network Adapter and Broadcom Netlink(TM) Gigabit Ethernet. I am not sure if these are adequate. I was using Commlink and aircrack but not sure if they are compatible and which versions i should have installed. I got as far as the collecting packets stage but the packets that appeared said ENCRYPT which was not correct and then my computer went to blue screen adn shut down and I had to system restore.
I was using my laptop - working in MS Word and hadn't even opend a internet browser and suddently a command prompt appears and all i managed to see before closing it from the task manager (which had it running through internet explorer i think) was that it was copying files.Its a work laptop so i would like to know if it was remote access from IT which seems doubtful on a Sunday or if i need to be concerned about security. Is there a relatively easy (considering i have zero programming experience) way for me to check if anyone logged on with remote access and who and what files were copied?
When I turned on my laptop today I noticed there was a new icon in my Network Connections section. It's called Internet Gateway. I haven't downloaded anything (weird or otherwise), I'm still able to connect to the internet and nothing seems to be amiss.
I use my desktop for streaming media throughout the house. I found it was causing lag for gaming most likely because it was taking up all the bandwidth for the router. We had a 2nd router laying around as well as a 2nd wireless adapter so we set up a 2nd network that was not connected to the internet for strictly media streaming.I attempted to change the network settings so the internet connection appeared as a public network so that streaming of media was hopefully diverted to the non internet wireless adapter.I want a faster way of transferring large video files from my laptop to my desktop. I recently bought a crossover cable to do this through direct connection.Both use the same user name and password as well as run the same win 7 pro however the desktop is the 64 bit version. I set up both ipv4 with the same addresses.When it has worked I am only getting a connection speed of just over 10mb and once I connect the crossover cable between the computers it knocks out my internet connection on the wireless card.
I reloaded XP on an old laptop I have, a Toshiba Satellite, and it works fine. Problem is when I try to connect to my wireless network, it comes up as being security protected...and it isn't...and never has been. I have other computers connecting just fine, but I can't seem to figure this one out. I don't have a key to enter as there isn't one! I installed a USB wireless adapter, and it works fine, but I don't want to use the adapter on the laptop.
The only way we can use our Motorola router is unencrypted. I have gone into the router numerous times and reset it, unplugged it, retyped the WEP key, tried to shift to WPA and nothing works. None of three computers in the house will connect unless all encryption is off. We live in a good neighborhood on a cul de sac, don't get a lot of traffic through here, and know the immediate neighbors, but nothing is stopping a stranger with a laptop from sitting on the street and using our wifi. I've talked to the Comcast tech. The trouble just seems to be our boxes won't get past the WEP encryption stage.
I have XP running on this older laptop for my kids.I wish to connect this laptop wireless (WPA2 encrypted) with the internet AND with other hardware in my home (other pc, harddisk, mediaplayer, printer).I know it can be done in windows 7, and Microsoft also had a virtual WiFi research project for a WEP encrypted visual WiFi.But as said I need a WPA2 encrypted virtual WiFi for a laptop running XP.
I've noticed, that ACS 5.1 is writing .gpg archives for backups. I'm about to upgrade an evaluation system and the Installation and Upgrade Guide tells me to do a full backup and restore in order to upgrade an eval to a production system. [URL] (second note in section "Evaluating ACS 5.1)
Question: can the production system sucessfully decrypt the backup? According to my personal gpg it is CAST5 encrypted with one passphrase. Is this passphrase constant for all ACS 5.x?
Packet Sniffing is mainly used on non-switched networks to display data that was supposed to be sent to nodes other than yourself, allowing you to see information such as usernames and passwords etc.My question is, why can this technology not be used as easily on a switched network? When nodes send data through a switch does it become encrypted?
This is a 5-year-oldish Gateway MX-6124 laptop running under Win XP 2002, SP3. I'm using SureWest DSL, with an ISP-supplied ComTrend NexusLink 5631 Modem/Router. The router is set up as a Secure Network, using WPA encryption. The laptop wireless operation light toggles off/on correctly using Fn-F2 control keys.I can connect to an open or non-secured wireless router, & have verified that at my church, at the Public Library, and at Starbucks. However, I cannot successfully connect to a passworded secured wireless source. I tried to use a secured network connection at my church yesterday, and could not connect. It "tries & tries" and eventually gives up and displays a cannot-connect type of message.
The laptop has worked correctly for several years on my home wireless network. It only stopped working about 3 or 4 weeks ago. I cannot recall changing anything in setup; I probably did it accidentally.I've spent about 2 hours in a couple of sessions with SureWest tech support. They diagnosed router setup using direct connect to the router, plus they talked me through several attempts at configuring the wireless config setup on the laptop. Everything I reported to them on the config settings appeared to be just fine. They also deduced that the wireless config on the desktop & router was correct.SureWest techs finally concluded that something was wrong with my laptop software config or the hardware, disabling it from making a encrypted connection. That sounds right to me, now having witnessed the secured connection failure described above, at my church wireless site.
I've looked at all the refs & things I can think of, plus followed step-by-step directions a couple of times with the SureWest techs. They rightfully pointed out that they could not make a tech support repair call on what did not appear to be a SureWest-related problem.I can easily make screenshots of any config screens needed on the laptop & upload to this forum.
I am actualy trying to make a remote access VPN between a ISR1921 and Windows 7 pro. I already managed to put a PPTP VPN with an authentication against our LDAP databse via radius. But our password are in SHA1 in our LDAP, so I had to let the password unencrypted on the network using pap and this is bad.If I don't use pap, it simply doesn't work since all the other method need unencrypted password for the challenge authentication.Does that mean that every remote access VPN keep our password unencrypted ? Maybe use EAP (but I can't find a howto or good documentation about it)? Can I add a certificate or something?
Is it possible to configure an IPSEC GRE tunnel with RIP on an SRP527w? I see RIP, GRE & IPSEC are all possible.. But I'm not sure about them all together securing the GRE tunnel??
I basically want to do this with the SRW routers not native IOS. Single head end hub & spoke.
I've configured an ASA5505 to be Lan to Lan VPN tunnel endpoint, peering with a linux box. The ASA is full licensed so that side isn't an issue.PROBLEM:When the tunnel is initialised from the linux box everything comes up okay except the ASA isn't encapsulation any packets. It is decrypted the packets received from the Linux box okay but no return traffic is being encrypted.When the tunnel is initialised from the ASA, nothing happens.After some troubleshooting I've found that the ACL defining interesting traffic nor the ACL defining NO_NAT aren't being hit at all.
ACL for NO_NAT: access-list NO_NAT line 1 remark ACL USED TO DEFINE WHAT TRAFFIC NOT TO NAT OVER THE VPN access-list NO_NAT line 2 extended permit ip host PAMS_SERVER object-group LINUX-BOXES 0xc736d5fb access-list NO_NAT line 2 extended permit ip host PAMS_SERVER 10.11.228.0 255.255.255.0 (hitcnt=0)
[code]....
I've checked with the administrator of the linux box and the definition for interesting traffic is exactly the same (except in reverse as should be the case).The firewall is doing other things like NATs and such like too but those NATs have nothing to do with this VPN. The setup is a LAN to LAN connection with no natting in between.The main parts of the config are attached, i've deleted things that should have a bearing on this however if you think it necessary i can sanitise the config and re-post. I think it will be working fine as long as the traffic hits those ACLs, however they're not and I'm unsure why.At this time i'm not seeing anything at all when doing an debug cry ipsec or debug cry isa. The ACL's aren't being hit so i'm guessing it's not even trying to form the VPN as it can't see any traffic that constitutes being 'interesting'.
Got to set up a site to site VPN to one in a clients office and we're struggling to get Phase 2 working, just seems to loop around saying "Received encrypted packet with no matching SA, dropping" which to me means the ACLs arent mirrored correctly?
Our campus using WisM (WS-SVC-WISM-1-K9) as wireless controller , Cisco 1130 access point and Cisco Secure ACS 4.2 Solution Engine 1113 Appliance as radius server. For username and password, ACS will export the data from Oracle database (production DB). The problem that we are facing right now is password that store in oracle database is in encrypted format. Base feedback from our database administrator, the encryption is done by oracle - application layer and cannot be decrypt back. In Oracle they call it "Oracle Stored Procedures" My questions :
1- Can Cisco Secure ACS 4.2 work with Oracle 10G or 11G?
2- Is there any option to tackle the encrypted password? Can ACS handle the "Oracle Stored Procedures" function?
are the connections between the ACS and external identity stores encrypted?I know that when setting up LDAP identity store there is the option to specify SSL conection. Are the other connections encrypted by default, or is the data sent between the ACS and AD, for example, sent in the clear?
The design is typical Cisco unified wireless solution. In such a implementation, is the traffic from the guest user who has successfully authenticated via WEB-AUTH encrypted? If so, what is the standard used, AES128 or TKIP?
In my company we put a RV042 router to connect two links to internet, but we have problem to enter a bank. The solution they gave us was to disable encrypted session balancing but I don´t know how to do it.
I installed a 1941 router with an encrypted GRE tunnel yesterday. The router has ipbasek9 and securiyk9 licensed. Initially the router was running the image c1900-universalk9-mz.SPA.150-1.M5.bin and was working fine. The tunnel was up and passing traffic. I then upgraded the IOS to c1900- universal k9-mz.SPA.151-2.T2.bin and when I reloaded the router the tunnel was stuck in a reset/down state. I tried doing shut/no shut on the interface and reloading the router again, no change. Being under some time pressure to get the device back into production I rolled back to the previous IOS image and the tunnel worked fine again. Is there a known bug that causes this behavior? I have searched cisco.com but have not found one. [code]
I have a new Inspiron 7520 and having issues with connecting to my secure network. In trying to troubleshoot the issue, I've discovered I can connect to my network when the connection is unsecured. When its encrypted, my connection is only limited (no IP address assign). I've also downloaded and installed the latest drivers with no resolution to my issue.
PC and Network Specifics: PC - Inspiron 7520Wireless Router = Netgear N600 - model WNDR3700Wireless Network - 2.4GHz b/g/n, WPA2-PSK [AES] System - Windows 8, 64-bitWindows IP Configuration
if I can use the encrypted port as unencrypted ethernet ports? url.. Each individual port on the Cisco Nexus 5010 switch is numbered, and groups of ports are numbered based on their function. The ports are numbered top to bottom and left to right.There are 20 to 28 ports on the Cisco Nexus 5010 switch, depending on which GEM is installed.
The 20 fixed ports form group 1 and are named 1/port_number. Ports 1 through 16 are unencrypted Ethernet ports. Of these, ports 1 through 8 are 10-Gigabit Ethernet and 1-Gigabit Ethernet-capable ports. Ports 17 through 20 are encryption-capable Ethernet ports.
I use a wireless adapter to connect to our home network but its stopped receiving packets but is sending them. It has worked fine for ages now it just randomly stopped. The network works with everything else (laptops, Xbox and iPods) but my pc wont receive anything. Also our home connection has no password as we live in the middle of nowhere.
I am having a really hard time with a computer that has a wireless connection. Specifically the internet keeps going out. The computer info is that of the affected computer and not the host computer to which the router and modem are connected.
I've no experience in VoIP and been ditched with looking at an IP trunking problem on our network.The users where getting dead lines or silent calls, but it seems after re-seating IP trunking card here and there around the network a few times, all is settled to normal. Unfortunately it's a third party that look after the majority of the telephony, and as they can't figure out why this happens they often say it must be a problem with the data WAN it traverses.So I started trying to figure something out, I have IPSLA monitoring setup in Solarwinds on most of the routers and all looks well from that aspect; MOS is 4.34 and Jitter is only 1ms at worst. I've taken a wireshark packet capture of the IP trunk by mirroring the port on the switch at a main site where I've been told a lot of calls are routed through. Inside wireshark I used the 'telephony> voip calls' tool and decoded all the calls. The output is showing most calls have 'Out of Seq' and 'Wrong Timestamp' at around 25-50%. Although these calls seem fine otherwise, and I took this capture whilst the fault was not occurring. I know I need to capture next time when the fault is occurring, but this is what I have for now.How can i fix this or even start to troubleshoot further?
p.s- each site has two routers running GLBP to the WAN, over two ISP locations. I read something about having consistent routing to avoid packets arriving out of sequence, but haven't found anything yet to say this is how I can/should do that.
Ive just downloaded wireshark just to mess around and ive noticed that even when ive got nothing open its still capturing packets. It gives me a choice of interfaces i want to choose to monitor and i would of thought it be "Realtek PCIe Family Controller" as this is normally the default one (im using wireless) but its saying no packets are being captured from this interface its the "Microsoft" Interface thats capturing the packets. Ive attached a screenshot, i know this isnt nothing bad but was just wondering 1) why isnt my Realtek PCIe interface capturing anything?
One Day the internet is fine the next day The Internet Stopped working. The problem is my pc is sending packets but not receiving any i though it was a bug or something so i restarted my pc after i restarted my pc the internet was working fine until a couple of minutes passed it stopped receiving packets again.i tried resetting the modem but nothing worked.I tried winsock fix or resetting TCP/IP and stuff but nothing workscause its starting to frustrate me.
Our computer is sending but not receiving packets. We've tried 3 different wi-fi adapters, and that wasn't the problem. We have no idea what's wrong? It won't pick up any wireless signals by the way, and it works fine while connected via Ethernet.
