I am setting up a Linux apache and bind server to test the behaviour of Windows XP,Vista, 7 and Mac OS X.I have setup a apache and bind already and they were tested individually. I used Firefox and IE to access the apache page by type in the IPv6 address and the page was showed correctly. And I have tried to query the AAAA record of a local zone "testing.com" in my Bind server using nslookup and the result is good too.However, it is strange that I cannot get it work if I type in the FQDN "http://testing.com" in Firefox and IE. I tried to capture the IPv6 traffic in Wireshark (Attached in this post) and there are no DNS query when I try to access the page. Is there anything that I have to set to get it work properly?(Actually I have tested the same thing on Mac OS X and Vista too but the result is the same)Below is my Windows 7 network setting and some nslookup query:
I was unable to telnet in to a SQL server on port 1433 to test the connection from the client PC.the application could connect and this alone verifies it is working on port 1433 for sql.My question is how can a telnet command on a specific port be blocked ?
I think I know what I'm talking about here, I just need someone to confirm that what I want to do is possible, and the way Im planning on doing it will work..Basically, I have a sky router (sagem model), and the wireless is weak upstairs in my house.So, I have ordered a new access point.What I want to do is keep the same wireless ssid and key etc, so my devices just connect.
Is it possible to find out the IP address of a PC connecting via Remote Desktop Connection.Running XP Pro on a network,I have admin rights to the PC's, but no direct access to the servers.Event viewer shows some details, but no IP address.
i have a query regarding the no. of isakmp policy priority creating..when i create a new policy in ASA 5500 firewall, i get the below error...i assume it will support only 20 nos, where as we can use between 1-65535.. can anyone from cisco confirm it...running version is 8.x & VPN Plus license.Policy limit reached. No more than 20 isakmp policies can be configured.”
I inherited a PIX 506 with 6.3. I will admit my background is more towards switching/routing. But while I know it is dinosaur, I need to maintain for partner interoperability. I just want to confirm that what I am thinking is correct and inf not how I can correct it.My thought is that since the access-list command doesn't list "eq" at the end, all ports and protocols are allowed?The other thing I am not used to is that the access-list has not id/number included in the command, so I assume that access-group specifies this functionality.
We have subscribed for MPLS links from Service provider we have a DC where the core connectivity is 90 MB and Remote branch location Connectivity is 64 Kbps. We are in process of enabling QOS for our links with co-ordination with Service provider ; as per our finding the branches have more RX traffic (downloading) so after discussion with provider we were advised to mark traffic from the core end and give it to the provider.The provider at its PE will honor the marking and set some B/W percentages and prioroty based on the DSCP marking values.
We need to mark this traffic so it is feasible to mark the traffic at the core DC router which has the below H/W details,Cisco 7206VXR (NPE-G2) processor (revision A) with 917504K/65536K bytes of memory. Processor board ID 36161439 MPC7448 CPU at 1666Mhz, Implementation 0, Rev 2.2 6 slot VXR midplane, Version 2.11
or is it feasible to mark the traffic at the core switch.
I am in the process of planning our new network. Our business is changing from hosting its own data centre, to moving it to a professional facility. We have 120 users, over 100 servers (physical and virtual) and three sites (main premise, data centre, dr site). The new network will connect all three. Our new WAN links are almost ordered. We will be making use of a managed MPLS IP VPN, with a 100M access rate at each site. I am currently focusing on the desing of the network at the main business premise. We have a significant investment in Cisco 2960 & 3750 switches and Fortinet firewall appliances. I plan to re-use these in the design.
Our current LAN is very flat and I want to segment the network. My plan is to create a number of VLANs, enable the Inter VLAN routing on the 3750 and then attach the 3750 to the Fortinet appliance which will provide stateful firewalling and traffic policin based on the VLAN (subnet) addresses. It is important that the traffic be routed as quickly as possible from this site to our prod and dr data centres.The 2960's act as the access layer, the 3750 as the distribution layer. The 2960's will connect via port channels (layer 2) to the 3750's and the VLAN interfaces will be configured on the 3750.
I was then planning on creating a VLAN on the 3750 to connect to the Fortigate appliance with a /29 address to limit the addresses used whilst also providing some flexibility for any future design changes.I want to implement a little security between the VLANs on the 3750 switches. I have a question about this coming up.I then plan to use the Fortigate appliance to do basic traffic policing based on source/destination addresses.
The WAN routers will connect to the Fortinet appliance on a Gigabit copper interface. The WAN routers will run HSRP between themselves and only one router will be active at any one time. The failover will be managed by the Fortigate and Cisco routers.I plan to define those addresses hosted at the other data centres and associate them with the interface associated with the WAN.I will then define the routing on the firewall for the two other data centres through summary routes for each of the sites. We will run static routing from the Cisco 3750 to the Fortigate and Fortigate to WAN router. We have no other networks/sites and won't have any others in the future.
We have Cisco 7609 Router and one 6 Mbps link which is on ethernet . When we are trerminating on Gigaethernet of 7609 router it is not coming up. While same link is showing up and working fine on other routers which is having Ethernet interface.
I have a Linksys RV042 and I came aceoss the setting " Dynamic IP+Domain Name(FQDN) authentication" setting under the Local Security Gateway type. How this option actually works. I tried googling but couldn't find a proper link.
I would like to be able to query the dot1dStpPortState obect on the Catalyst 2960-S on our LAN . Im running firmware c2960s-universalk9-mz.122-55.SE2.bin and according to the Cisco SNMP Object Navigator the object is supported (via the BRIDGE-MIB).However when i query using snmpwalk from my workstation :snmpwalk -v 2c -c bic-zua-ro 10.u.y.x 126.96.36.199.188.8.131.52.15.1.3 I receive and error .SNMPv2-SMI::mib-184.108.40.206.1.3 = No Such Instance currently exists at this OID For the sake of comparison, querying our 4700 :snmpwalk -v 2c -c bic-zua-ro 10.u.y.x 220.127.116.11.18.104.22.168.15.1.3 returns (as expected, cropped)
Whenever I try to use Firefox, no matter what website I try to go to, I get the message that firefox can't connect to the server. Whenever I try to go on safari, I get the message that it can't connect to the internet. However, when I use Opera, everything works fine, so it's not something wrong with my internet. At the same time, the website omegle stopped working for me, I don't know if this is related. When I open firefox, I also get the message "TypeError: Components.classes[cid] is undefined". I don't know what that means, but it's probably involved.
On my PC laptop, when we try to connect to the internet (wireless router) through firefox we get the error message"Firefox can't establish a connection to the server @ cn-us.start3.monzilla.com. When we try using Window explorer we get "Internet Explorer can't display webpage" When prompted to click on "diagnose connection problem" it states Windows did not find any problems with this computer network connection.
A couple of points... the connection indication at the bottom states the laptop is connected to the internet. (WLAN ON)I have a Mac that is connected to our internet and doesn't have any problems.We have Windows Vista on the PC laptop
I found my dir-601 router keeps making arp query to all ip addresses in same network periodically.all dhcp clients are general laptops and smart phone, I don't think there are any arp cheats attack on those devices.is it normal?
model: DIR-601 hardware version: B1 firmware version : 2.00NA
in my simple network setup, I cannot resolve DNS queries from inside my NATted network. On the router I can ping both IP-addresses and names. Ping from the local machine works for IP-Adresses but not for names. When doing nslookup, addresses are not found and a SERVFAIL message is returned. I use a Cisco ISR 861 Router to connect our local LAN to the Internet (The WAN of the 861 is connected to another DHCP/NAT-Router, which in turn connects to the ISP-Modem). Addresses in the local LAN are DHCP-distributed, the DNS-Servers from my ISP are configured on the Router and the DNS-Information is distributed correctly to my local LAN machines (as I can verify by doing nslookup on Linux).
I'm looking at a stack of WAP200 and WAP4410N APs. I'd like to use Cacti to track number of associations on each AP.What's the OID I should be querying? Are there multiple OIDs that would correspond to the multiple SSIDs? I'm running 2 SSIDs on all of them, and it would be extra nice to be able to track number of stations on each SSID, though the total number would also be acceptable as well.
WIth Chrome it does work although a bit slow. With IE as-well.Had the problem with FB as-well allthough that i could cancel with allowing it to connect.Gmail doesnt.Production Security Services and the certificates seem to cause problems.Searched the internet; tried a scan, checked the date, activataed the SSL and TLS in the browsercertificates, the server and organisations names.
A few days ago, all search engines stopped working on my computer on both IE and Firefox. Everything else works fine and I can surf the net using specific URLs but I can search for anything. I have tried a number of options and various anti-virus, spyware and malware scans but no infections are ever found. I have used, AVG, windows defender, and Malwarebytes.
I have a Windows7 laptop that was working fine til yesterday.I switched it on at home last night and it picked up my wireless connection but when I opened IE or Firefox it would not access any webpage (blank screen, no address that its resolving on status bar at the bottom and just a progress bar (IE) or a 'searching' icon (firefox)The network connection page in control panel says that it is connected and I can ping sites from the command prompt and some other software such as skype seems to be connecting.I have disable both bullguard firewall and made sure the windows firewall is off.I have come into work this morning and am getting the same problems, even when connected by ethernet cable, I can also see other computers on the network.I was occasionally getting a dial up connection pop up box appearing from an old dial-up connection I had set up, but have now deleted this connection.
I cannot connect to the internet using firefox or chrome but there's no problem with internet explorer. This happened after I installed and uninstalled speedbit video accelerator. When opened chrome, it gave me the following error.
(net::ERR_NAME_RESOLUTION_FAILED): Unknown error.
After the problem occurred, I rebooted the system, uninstalled firefox and chrome, freshly downloaded firefox (from IE) and the problem persists. I couldn't download chrome because chrome installer says it can't connect to the internet. Following are the details regarding my system and software.
o/s : windows 7 ultimate internet explorer : 9.0.8112.16421 64 bit firefox : 14.01
I tried stopping the firewall and the problem persists. Can't access router via firefox too!! Firefox doesn't give an error it just gives a blank page (about:home).
If this is a dns problem, how come it doesn't affect IE ?? Why can't utorrent listen on listen port ??
I am having trouble opening firefox as well as itunes. I get a message stating that i am not commected to the internet. I am able to connect to the internet using internet explorer and have no trouble logging on to websites from there.

Am experiencing the same problem where IE can connect to internet, but not Chrome, although the only change to my desktop PC (WinXP SP3) was a windows update. This issue seems to be quite common among all Windows OS because when I queried "can't connect chrome to internet" I've found over 50 posts at various forum describing your issue (and mine). I have also eliminated firewall, antivirus, etc and obviously since IE can get on the internet..my network connection is fine...as is/was yours. Looking more closely I'm thinking that somehow the specific port on outbound is not being accessed by Chrome/Firefox because I used a sniffer and see no request leave my pc and verified no request through my router either.
The winsock catalog in a namespace server configuration listing right? How would you explain that resetting the winspace catalogue fixes the issue?Wand3r3r said it was malware, but I'm quite sure we don't have that issue...I know my machine doesn't and this has occured on the library PCs also. I wan't to find sure fix and understand what is happening on the Windows stack, so that I can assuredly deploy Chrome on a student network and not see this re-occuring all over the place.
"How do i setup a proxy correctly using firefox?"I forgot what addon it was that i was trying to use, proxy fox i assume. If there any better firefox proxy addon that i can use i will be happy to use.I want to know the steps to make the proxy work correctly, because i like to be anonymous as possible when using the internet. I don't care about internet speed.
