  It seems that you may have more than one DHCP server on your local network.

  What is the basic configuration of your current network? In other words, what is the brand & model of your modem, gateway or router? You have a dedicated server or another client on the network that provides the DHCP service?

• Back to 'mac address cloning.

  My latest issue of 'mac address cloning' has been resolved, but now I have another. Before, I had to reset my router to turn off and reset everything and it worked. Now I have to activate "clone mac address" to get my pc and the server let me contact them (thru 'MSTSC') with my wireless laptop and then I have to disable it to get on the internet. Is there a way for the pc and the server to be reset and start fresh?

  It is most likely a name resolution problem. When you don't have the address cloned MAC and you ping dan - pc, do you have the answers?

  Unless you have a server configured on your network, WINS all of your PCs have static on the router DHCP leases, or if you run your own internal DNS server, or if you have the file for all of your internal machines LMHosts entries, it is unlikely that you will be able to be able to resolve the names of the computers on your local network.

  Probably the easiest way for you is to refer to their IP address. If you have changed the port they listen to on, so you can access separately from outside your network (when you're not home for example) you must add this airport number to the IP address in the input address mstsc block, IE 192.168.1.10:3389 for them and 192.168.1.11:3399 for the other (this is for example...

  Of course you can.

  Well, you should be able to do it, but until you're able to explain more clearly what you are doing, so that we can solve the hang up, it is impossible to determine how to help you.

  So, you can make a backup with Desktop Manager if you prefer. Then use ABC Amber IPD Converter software (google to find it) to extract the file backup IPD to your address book.

• I would like to move the button reload of the address bar. I also have a visible 'next' button and the back button.

  Simple as that. Because I have OCD, it is extremely unpleasant to have both forward and back buttons is not always visible. How can I return to this appearance?

  I also want to separate the button reload of the address bar, as I had before the update. I'm reloading of pages often enough and have the button smaller and in the address bar, it's... a little counterintuitive.

  Ideally I would have ordered it, from left to right: back, forward, reload, address bar.

• How does the virtual machine BACK to Windows?

  How does the NTVDM?  I run an old DOS program written in Fortran 77, which, with the exception of the database has not changed in 20 years.  It takes about 2 hours to start a business.  My boss told me that I can get a better computer.  Upgrading my computer 3 GB RAM maximum 4 GB will make a difference.  When I use the MEM command, I thought that the memory in use is what I take BACK used, approximately 1 MB.  Am I missing something?  More RAM can help?  Help a different CPU architecture?   The little knowledge by going to various sites, I have gained seems to tell me that dual core or quad processors are unnecessary because BACK is a single processor and use it exclusively.  How about a faster chip.  Is there a limit to the speed that is finished on the BACK.  Then addresses NTVDM maybe all these problems Unlike DOS itself.

• iPhone will start

  Yesterday my 6s iPhone crashed and turned back and all my photos wiped for maybe 5 minutes and then they all came flooding back. Then my phone started acting really slow all by doing something like opening the apps and I had off maybe two times three times during this time to see if she could solve the problem and he didn't. At this time, he got extremely hot so I turned off the phone and he was left in charge all night. Now, whenever I press the lock button to turn the phone on, the apple logo shows for a minute, and then she just turns off again. Help?

  Have you tried troubleshooting?

  1. Restart: press start/stop button until the Slide to Power Off slider appears, select Slide to Power Off and after it stops, press on On / Off button until the Apple logo appears.
  2. Reset: press the home and On / Off buttons at the same time and hold them until the Apple logo appears (about 10-15 seconds).
  3. Restoration: connect your iPhone to iTunes on your computer, backup, and then select factory restore.

  Make an appointment at the Genius Bar in Apple for the service. If you need a Apple Store - find a store - Apple.

• I have problems with my 7510 holding a wireless ip address 192.168 etc. He said 169. etc.

  My HP Photosmart all-in-one (which is only a few months old) stopped communicating with my router Netgear DGN1000 Adsl a few days before Christmas.

  Instead of the 192.168.0.9 ip address that he used before I turned off the router, ITI is back with an address of 169.254.249.128; 'Source setup' = 'Auto ip "; a subnet mask of 255.255.0.0; and default gateway 0.0.0.0. I know that they are bad, so I tried a fixed ip address to 192.168.0.201, a SM 255.255.255.0; and a DG 192.168.0.1; It was OK, but the next day, returned to the auto ip settings.

  I finally managed to contact HP and the guy spent 75 minutes with me trying to restore things and finally the village that the Netgear router did not have access to the printer via certain ports (which he sent me a list of) and something he said that I had to tell my ISP (Virgin media) "FLOOD DETECTION SET to OFF" & "SP1 FIREWALL SET TO OFF.

  Communicating with VM, they were insistent that their router was not at fault - they could open ports 12 or so, at a cost to me of 60 pounds! (I refused this)

  HP told me how to set up for printing Ad Hoc (bypassing the router), who had worked during our tests.

  VM has been in my settings for the router, via a remote access device and verified a few settings, but the only one, I saw them alter was CH10 CH11 to change.

  I could certainly not the printer to accept the 192.168.1.201 after that anyway.

  As a result, I have reset the network default printers and reconfigure wireless settings. He seemed OK and running on 192.168.0.9

  I have now reset IP address in the manual on the printer, by entering the 192.168.0.9 and 255.255.255.0; and 192.168.0.1;

  Touch wood he delayed for a few days, but I havn't turned off anything (but during the night before it went wrong!)

  I'm not convinced I have a solution here and would welcome any suggestions as to what I can still do it.

  Maybe I already have some, as I "completely uninstalled and reinstalled the software HP7510 on my desktop PC.

  Incidentally, the printer is set up on 3 PCs in the House - a desktop computer under W7 HP 64 bit, a laptop (same model with BONES) and a laptop under W7 HP, but 32-bit computer.

  All were unable to print when I had problems.

  I would appreciate any suggestions for a fix permanat more. (I would have rather found a final breakdown) I have all other routers, I could try, or I could open ports, but my question is - if I had need of these open ports and other settings (detection of flooding etc.) why the work of the printer for the first few weeks I had it implemented, and why turn off the router caused these issues? (Assume that I need in the future - to turn off the router happens)

  Thank you

  Dave

  Hi Dave,.
  
  Great post with good information.
  
  As you mentioned, the printer came back with a style 169.xxx.xxx.xxx IP address. This is normally produced when the device is not able to get a full connection with the router, router it gives an internal IP address.
  
  Normal suggestion when a printer continues to maintain a connection is to assign a static IP address. This is done by using the manual IP functionality, you've talked about using. This locks the device to the network settings, and even when the network is restarted the information is preserved. This should be the solution to the issue.
  
  I hope this helps.

• TCP Hijack on IDS signature

  Someone has a lot of experience with the 'TCP Hijack' signature on the IDS sensors? I checked the NSDB and docs IDS for the engine in question, but neither go into details on how to determine if alerts are false or true positives.

  Any comments would be much appreciated.

  Thank you very much

  Matt

  Under the version of Cisco IDS 3.x, Hamid 3250 only looked at a few ports (TCP 21, 23, 513 and 514, if I remember correctly).

  With the introduction of version 4.x, the signature was no longer limited to these ports. Thus, at least here, we were see a large number of "false positives" involving the web proxy traffic and NetBIOS traffic. BTW, I have no idea if the signature has been coupled to the ports under version 5.x (someone?).

  The logic that we apply to all alarm hamid 3250 we see here is based on two factors: intent and feasibility.

  Although it is theoretically possible to divert most oriented session TCP connections between a client and a server, there are some that simply make no sense.

  If you take alarms involving TCP port 80, what would be the point to divert someone connecting to a web server? Anything sensitive that someone could do this using a browser is done via HTTPS (SSL/TLS aka), so Cryptography will eliminate the threat of hijacking it. So now you re left with web access unsecure. what you are more likely to find if divert you this? Someone looking at the comic strip Dilbert, or something as I imagine... I think you will agree that, therefore, there is no intention at all.

  As with any attack of diversion, the feasibility is quite low. Most of these attacks requires that the hijacker be in the same domain as the intended victim. That being said, it goes without saying that you aren t also see cache poisoning attacks ARP or TCP Syn flooding (or another DoS attack against the victim), you aren t see a valid hijack alarm. Of course, the problem here is that these activities usually occur in an area that is not supervised by a NIDS, then you will need other corroborating data to see (HIDS/NNIDS, router logs).

  In all cases, these alarms are not very useful on their own. When they become valuable, in my opinion, is when they appear in concert with other alarms (e.g. Hamid 7105 - imbalance of ARP requests).

  I hope this helps.

• the ASA 5505 configuration

  Hey guys

  I have a server that accepts traffic on a port within my network and external clients need to access this server. the nat and accesslist works well, but it is a matter of wait time and connection failed... Note that without the client server asa directly works fine... and note also that the traffic is encrypted (ssl)... are there additional provisions that I have to configure? y is it expire? Packet Capture see traffic from the outside to reach inside the interface but no response from the inside to the outside...

  I don't have that only one access list reloads the traffic from the outside to the server and a nat rule.

  advice needed...

  Thank you

  Hello

  So from what I understand

  "inside the xxx.114 interface the default route on the server is xxx.1 which is one interface on another asa.

  This means that the default route on the server is an another ASA. It won't work unless you apply TCP statebypass.

  ASA is a statefull firewall. This means for the TCP IP, always see two way traffic. If SYN crosses an ASA should see SYN/ACK back. If an ASA did not syn and sees syn/ack due to asymmetric routing, is wrong in the wok.

  Change the default route in the same ASA server or configure TCP statebypass (which is not recommended however).

  Thank you

• [RVS 4000] Secure setup ACL

  I want to do an ACL that will allow traffic minum. For example, only; HTTP, DNS, SSH, FTP, TeamSpeak, Torrents.

  This doesn't seem to be possible with the ACL on my Cisco Small Business RVS4000, I can only choose predifined parameters.

  I can't configure my own source and destination IP and port. If it is not very useful.

  I may be wrong, that's why I posted this threat. Is there a way to allow a minimum circulation with the ACL?

  When I don't allow HTTP, DNS, etc. and deny the rest I can't use my TeamSpeak and Torrents, MSN more.

  That's what I have now and that works, but it is not safe... Check the screenshot below. Here's my configuration of iptables, an ACL like this would be my idea of secure
