After Few Hours The Tcp / Ip Protocol Stops Working
Oct 14, 2011I'm having is that every few hours my TCP/IP protocol stops working. The modem lights remain normal but I can't connect to anything. The only thing that works on the internet is traceroutes at the command prompt which function normally. The solution is that I have to reboot and then everything returns to normal until a few hours later when it happens again. There are no error messages on any of my browsers. The page just goes white immediately. When I try to retrieve my email, I get a message about the TCP/IP isn't working.

Mar 22, 2011The IP defined in RFC 791 was the first widely-used version of the Internet Protocol. Interestingly, however, it is not version 1 of IP but version 4! This would of course imply that there were earlier versions of the protocol at one point. Interestingly, however, there really weren't. As I mentioned above, IP was created when its functions were split out from an early version of TCP that combined both TCP and IP functions. TCP evolved through three earlier versions, and was split into TCP and IP for version 4. That version number was applied to both TCP and IP for consistency.url... what i wanna know s in tat underlined line its given 3 versions of TCP what r they?

Jun 23, 2011I have a PPTP VPN server (WIndows 2008 R2) sitting behind an RVS4000, I have port forwarding for 1732 on and the client's (Windows 7) can reach the VPN server but cannot complete the connection due to an 806 error, which is GRE traffic related. I have PPTP passthrough on and have also created a ACL entry for PPTP traffic. I've seen many posts on this topic over several years with no solutions, and I do have the latest firmware (Version:V1.3.3.5). This is also definetely router related as I have absolutley no problem connecting when I point directly to the VPN server by internal IP address.

Jan 26, 2013I was working on a problem the other day and came across something that I had seen before but never given much thought. I had a router with a switch connected to it and the interface was showing as Ethernet0 is up, line protocol is down. The problem in the end turned out to be a cable that had fell out because it was not connected correctly, but I was able to replicate this interface status on a router (FastEthernet0/0 is up, line protocol is down), and NO cable was attached to the interface.I've had a look on the internet but cant seem to find a good answer, so does anybody else know why this status is shown on the router? Remember, NO cable is connected to the interface so it isn't a speed or duplex problem

Cisco Firewall :: QOS By Protocol On ASA 5512-X
Apr 18, 2013I'm looking to make a possible configuration for a customer. They need a device to provide :- firewalling- bandwidth limiting based on protocols, IP, users- web content filtering- good reporting to see which device/users are consuming most of the bandwidth.I used to use cisco ASA as firewall but it's a while I last installed on and I'm nt uptodate which current state.So I thought of using an ASA 5512-X but I'd like to know if it comply with all the requirements .Most important being the reporting and bandwidth limiting capability. It would be great to have some configuration example regarding bandwidth management.

Dec 6, 2011The Intel N-1030 just refuses to connect at N protocol. Its almost as if the N protocol has been disabled waiting for a real fix from Intel.
I have updated firmware, etc., for router. I have several N devices and ALL connect easily and quickly. I gave up for now on the Intel WLAN N-1030 and bought a Netgear N mini-usb dongle device. With coupons it was about 10 bucks at Staples. Popped it in and what do you know, connected at N in a blink of an eye.
If Netgear can get a mini-usb N device to work properly Intel and Dell? I have set everything as suggested, power to max, router channel to auto, etc. Why no selection for wireless mode b/g/n in driver but only the 802.11n mode option?
Something is not right with this driver and implementation of the N-1030. At some point Dell is going to have to step up and provide us with what THEY advertised as the hardware we purchased. Selling a device with N protocol wireless when in reality the N protocol does not work is going to be on Dell, not on Intel.

Cisco AAA/Identity/Nac :: ACS SE 4.2 RADIUS Protocol
Mar 28, 2013I am using the Self RADIUS server in my Cisco ACS SE 4.2 appliance S. I have an AAA client C that interacts with S by means of the RADIUS protocol. This works fine, in that S correctly carries out authentication chores on username/password (PAP and CHAP) pairs received from C, sending back to C the corresponding Access-Accept packet when the authentication succeeds, or Access-Reject when it doesn't.
I have been able to import a set of three VSAs into S. Each of those attributes is of string type. I then configured in S a single user U with password P so that, whenever a U/P pair received in S from C is authenticated by S, S should send back to C, in the Access-Accept packet, the three attributes with the following values: [code]
With this setup, when an authentication is successfully completed by S, C receives 53 bytes worth of data from S every time. I am attaching a typical example, already disassembled. I have disguised the actual vendor ID, for legal reasons, but the rest is exactly as it was when received in C.
According to the disassembly, what we got is an Access-Accept packet, as expected. Its length is 53 bytes - again as expected, for this is the only packet that C has received from S here. However, the packet is incomplete, for attribute #3 is missing its value field.
Looking into the whole packet in more detail, it can be seen that while the wire format for the first attribute, namely, Frame-IP-Address, is correctly constructed, the remaining are not. For example, the sequence of bytes corresponding to the attribute #1 reads 1a 09 00 00 xx xx 2c 61 62 63. I believe that this is incorrect; it should be 1a 0a 00 00 xx xx 2c 61 62 63, for the wire format for this attribute consists of 10, not 9, bytes. I tried a few variations on the values for the attributes, and the results are always substantially the same, in that the wire formats for these attributes are always incorrect.
This all probably implies I have done something wrong when importing the VSAs into S, and/or when configuring things on S. I am therefore attaching the csv files I used to import my VSAs into S; as before, names and vendor ID are disguised, but their lengths are exactly the same as in the undisguised file. I used two csv files: One to import the vendor ID, and the other to import the VSAs under that vendor ID. As for user U, in S's administration GUI I clicked on User Setup and selected user U, moved to the bottom of the screen, where the attributes for this particular vendor were present,introduced the values for each attribute mentioned above, and made sure that button in front of each attribute was ticked.

Feb 14, 2012I just bought 2 Nexus 7000 to upgrade my primary/Production Data Center from 6509/MSFC. I'll keep the 6509E/SUP720 for the DR Data Center. I have ordered two 10Gig Wan Pipes between the Production and DR. In other words between the Nexus 7000 and the 6509E.
My problem is that i do not know the best way to do the routing between the 2 Data Centers. Currently I have MPLS with a provider connecting the 2 Data Centers using BGP on the CEs and I'm running eigrp in locally in the Cores. After the 10Gig comes to life, the MPLS will go away.
My QUESTION: Should i run ibgp between the 2 Nexus and ibgp between the 2 6509E/sup 720 AND THEN run ebgp between the Nexus and the 6509/sup 720 over the 10Gig WAN? OR should i collapse everything into one eigrp domain/AS and just run Eigrp between the Nexus and 6509E/Sup 720 over the 10Gig Wan?
