I connecting to a Cisco ASA 5500 using a third party IKEv1 client. The initial connection and all rekey attempts that start on the client are successful. A tunnel is established, data cna be transferred between the client and the ASA's internal network etc.However, when the ASA initiates rekeying of a Quick Mode SA this is rejected on the client. The rejection occurs due to QM3's HASH payloading having a length of 4, which is wrong.
ASA log:
ISAKMP Header
Initiator COOKIE: 48 81 9e 1b 80 94 41 a9
Responder COOKIE: fa ab 87 c7 a5 d9 8d 35
Next Payload: Hash
Version: 1.0
Exchange Type: Quick Mode
[code]...
Since the initial negotiations work, pre-shared key, IKE/IPsec settings etc should be correct; if they weren't the connections wouldn't work in the first place.
We have a VPN configuration currently using a VPN3000 device. According to this [URL] and some others I seen DNS payload can also be translated in NAT configuration.How can I doing it with the VPN3000 box ? On my configuration DNS payload aren't translated, but it is maybe an option I need to set or unset !
i want to know that how can i send more than 1506Bytes in payload of ethernet frame insteadd of 1500Bytes(max size)? i have hardware device that can send variable length payload so what changes can be made for this operation
How the one-way hash is generated given the challenge number and shared secret password?It's just that I was reading Cisco 3 chapter 7, and it doesn't explicitly outline how the one-way hash is actually generated, it simply states that it is generated given the challenge number (randomly generated for every challenge message) and the shared secret password.
Is there any other way to configure the checks using the hash value of an application instead of register key ??? I have read and confirmed that the hash value does not change never. Its the same value....But I did not find a way to configure the rule on the CAM.... ? By the way I am using Cisco NAC 4.8.2
I have a 2821 Router with several IPSec Tunnels on it. I would like to replace this with a ASA 5510. My hope is to swap these out with minimal impact on the active Tunnels. I have the details of each Tunnel well documented. My question or concern is in configuring the Tunnels on the ASA. Do I need to configure IKE proposals in just IKEv1? If I use IKEv2, my concern is that there will be compatibility issues with the remote end of the Tunnels, or is IKEv2 functional with IKEv1? If not, then, do I just configure everything in IKEv1 and ignore IKEv2?
just upgraded my ASA5510 from IOS 8.25 to 8.42Everything is running fine apart from one VPN between ASA5510 and cisco 887V router.The VPN session is up but no data traffic is being passed through The tunnel although this VPN was working fine with old IOS. The tunnel is up but no data is passing through IKEV1 session.
Which transmit hash policies are supported by the SLM2008? I can't find this information in any of the documentation for this switch, all that is stated is that it supports Link Aggregation using IEEE 802.3ad LACP. I'm connecting to a Netgear ReadyNAS Pro that supports Layer 2 and Layer 3+4 transmit hash policies and I'm not sure which to choose (or whether it matters).
I have a L2L tunnel setup between two ASA's (v8.4). I used the wizard to set these up and selected the defaults of both IKEv1 and IKEv2, thinking that it would select one or the other. The strange thing is that now I see a separate session between these ASA's, one for IKEv1 and one for IKEv2. Both are passing traffic. Is this expected behavior? Should I disable IKEv1 to force only v2 since both are v8.
I was calculating packet amount of MPEG I use byte rate to divide by 188 byte but now i want to calculate H.264 encode video what is the packet length of h.264? is it same 188byte?
making EEM work to show first xx lines of CPU utilization. I found when I put cli command "terminal length 13", the EEM stopped working and timed out after 20 seconds. I have tried IOS 12.4(25d) and 12.2(53) with same results. [code]
I've heard that a method to optimize traffic is to use variable length packets. They say that the worst case is in minimum length packet (64 bytes). But I can't understand why.
I used 2 PC with gigabit NIC, use cat6 with short cable i've got speed 1000Mbps, but with longer cable(around 30meters) speed is 100Mbps. I'm looking forward to seeing from you soon.
I would like to know the meaning of 'set max-parse-length 8192' on ACE.Looking at Cisco documentation I found:"you can set the maximum number of bytes to parse for generic protocols by using the set max-parse-length command in generic parameter-map configuration mode.You can set the maximum number of bytes to parse for generic protocols by using the set max-parse-length command in generic parameter-map configuration mode.' what a set max-parse-lenght is?
I am installing a network in my small business and was given a spool of Cat5 cable to run wires... I know the length in feet of cable that I was given, but I was wondering if there is some kind of markers on the cable to tell me how much is left... I will be charged for it by foot after I'm done, and I want to know how much I've used. Do I have to just use a measuring tape? Seems unnecessarily complicated... I've checked the wire but can't see any marker of the length remaining.
In order to get from the coaxial jack on my wall to my cable modem I have to run about a 50 foot coaxial cable around the perimeter of the room.Will the length of this cable diminish the speed of my internet?
i need to connect modem to computer with the length of 150m. suggest which way is efficient to connect. which cable is efficient. is any medium needed in between.
The URL field in the web access log has a length of 70 characters. Is there any way to increase is[INFO] Mon Jun 13 21:30:30 2011 Website1234567890012345678900123456789001234567890012345678900123456789001234567890 accessed from 192.168.xx.xx
When you type a command in the terminal, if the command is too long is only displays the last half of it. How do I change it show it give me enough room to view the entrie command?
I have a Cisco WISM2 installed on Cisco cat 6509, with 39 indoor (3502i) and 14 outdoor (1310G) Access point, so the problem i am facing is that, the controller recognizes all AP and they are all configured and working well, then the signal of the outdoors (1300) its broadcast in a very short length like 60 meters, and i don't understand this is likely having a problem with a controller software version or ... being at 3m, my card does not show excellent signal strength and yet with the indoor thing are Ok.
Can the Cisco 3750 and Cisco 2911 enforce password length? Is there a default password length? I had read the following:You can specify a password length but not special characters etc..security passwords in-length
I came across this site. I wanted to produce a better incoming ACL at home and work to prevent known bad sites
Here is their list of the Top 10 Global Spammers is out. The biggest surprise on the list is Korea, as it takes over the number one global spammer spot from China. With the improved high speed internet infrastructure in Korea and ease of network access, who knew Korea would be on the rise.
Here is the complete Global Spanner Top Ten List for the first quarter

Korea China India Russia Turkey Viet Nam Ukraine Brazil Venezuela Pakistan
When I sort the list, it is over 16k lines of ACL!
My question relates to what performance limits I would find. Can I actually put that many lines in an ACL? Will the router choke and do any other work
I have attached the sorted ACL list for you to review
Any of the following router lines will accept a list that large and still run acceptably?
I tried to sign in with my DYNDNS account in the dynamic dns settings and the username field is limited to 15 characters. The problem is that DYNDNS does not limit usernames to 15 characters and my username is more than 15 characters. How can I get them to fix this?
I have something I assumed but I am not sure if this wrong or not. I assume that every say 1 meter, I can send say 1 bits, so if I have 10 meters of link length, I can send 10 bits of data on that link. Do you have any argument to strongly support this assumption, preferrably a reference.
I have an ASA 5505 with software version 8.2(1). It is making DHCP requests for IPSec clients that connect to the ASA. The DHCP requests packets the ASA makes have an extra '00' appended to the hostname field, and the length field is the size of the hostname + 1. The DHCP server is Microsoft Server 2003 and this causes the hostname to be registered with an unknown character which appears as []hostname. Then when server 2003 tries to update the DNS record, it fails because of the invalid character in the hostname. Is there anyway to have the ASA have the correct length for the hostname field in the DHCP packet, or a workaround that will solve this problem?
