An issue that we have run into is that on some of the machines, black areas appear over the screen at random times.These black areas disappear when the users mouse over and return when the mouse is moved back. The areas are usually small (about 30 pixels wide) and we have had to log the users off and on again.The machines that users are using are Thin Clients (HP and Wyse) and it seems to happen when certain programs are in use (Sage).

I hear a lot these days about ethernet deployment in metropolitan areas as access networks. Does this mean that there would be one big optical ethernet LAN (or MAN if you prefer) with fiber to the home connected by switches? Wouldn't this lead to massive spanning trees in large cities? One bad,configuration in the network would affect the whole network.Will all IP traffic have to travel to the core even if it is destined for an intra-MAN destination? I cannot imagine that a ARP broadcast in a large MAN is feasible.

Make sure area-278 does not receive any ospf routes from other areas as well as from ASBR routes from other areas. At the same tim, area-278 should be able send successfully RIP routes that we receive from R2 to backbone area.
View 1 Replies View RelatedWe are looking into the possibility of putting in some public wireless access in the public areas of our organization. Its a fairly small building in terms of public access and it needs to span 3 rooms in total. We have a spare BT line into the building - ADSL 2+ - and so will utilize that instead of putting them on our network. We would like to run some router based content filtering on the router - but would use open dns if this isn't possible.I could do to find a good wireless router that will cover the 3 areas . Its not a large budget project as there isn't going to be very highly utilized. We are looking Cisco kit - and have drawn up a few options. Initially we were going to go with the 1140's - but these are access points and as per my understanding aren't going to work with the phone line - as it needs to be a wireless router.
The next area was the Linksys E series (E4200) - they do look really good, and they have the content filtering which we like. What the power and range of the E series is? The only issue we might have is its a fairly old building and so some of the walls are pretty thick - one of which is wooden lined.It has the 3x3 mimo antennas and so guess it would provide some pretty good range/power. If the hardware is cheap enough then we may be able to setup the routers in repeater mode - however I'm not sure if the home devices can work that way? - I think max would be £300 - but that will be decided when I have some better numbers.
At random times AT NIGHT, while Call of Duty, Black Ops, the signal on the game goes red. I have spent more nights on the phone with ATT without resolution and refuse to call again. An ATT tech has come to our house twice, once to check the outside line and to look inside too. Signal to house is always fine.We bought the 2Wire 2701HG-B since ATT said that our problem was we were running a modem and seperate router. We even sent the PS3 out for service thinking it was the problem. Yet here we are again with a red signal in the game.On the modem, the ethernet and wireless flash VERY rapidly, its more like a strobe than a flash. The internet and dsl lights are solid. We are considering going to cable from DSL.
View 10 Replies View RelatedI recently inherited a Cisco 2911, that appears to have had Firewall rules imported into Externally Defined Rules. ACL's are currently allowing/disallowing traffic. However, there are no firewall rules configured. To meet compliance we need to have Packet Lavel Inspection (Firewalled) rules. There are two areas in the router, under ACL area, and under Security. What is the difference between these two Firewall areas?Are both areas providing packet level inspection?Can I build Firewall rules (within the Security area) to replace the ACL's?

View 1 Replies View RelatedSo I have two xbox 360's plugged directly into my dir-655 router with Ethernet cables. I have no idea how to port forward these, correctly and everything I try ends up with my router being reset. I don't have a pc connected to the router, only a wireless laptop.
opening ports for multiple xbox 360's (Black Ops is what we are trying to play).
One thing I do know is that when I tried portforward.com's walk-thru for port forwarding, when I enter the ports into the dir-655 port-forward menu, I can no longer connect to Black Ops at all, it says servers are down (WHICH THEY ARE NOT I CHECKED).
Does this board supports DirectIO to PCIe devices? I have one, and there is an option in the BIOS for IOMMU (disabled or 64mb) which dosent seem relevant? But ESXi dosent see support for pass through.

View 1 Replies View RelatedI ran the setup CD and can access my camera from inside my local network. When I try to access it from outside, I can access the camera fine but the video stream is black. I tried RTSP ports 554, 2080 and 5632 with no success (of course I port forwarded the dsl modem as well). My dsl modem is a westell 7500 and my ISP is frontier communications. I contacted their support tech and at first he ran me through the exact port forwarding sequence I had already done on the modem. He then went away for a while and came back to say that I need to upgrade to their fixed internet address service. I understand dynamic DNS and don't think this is an issue because I can contact the camera OK, I just don't get the video through (black screen). Another issue is that the camera is reporting PPPOE 'failed'. The support tech has given me two PPPOE user names and passwords but neither work. The support tech said that they do require PPPOE.

I have just installed two DCS-942L cameras and uses MyDlink. The live video is OK from MyDlink, but when I log on to the cameras from "Advanced Settings" the live video is just a black screen, no matter what video profile I select. Like wise I can't select motion detect area, because there is just a black screen.I have tried on tree different computers. What can be wrong?

View 1 Replies View RelatedBeen catching wind of an upcoming super fast router....the Asus RT-66U.Currently their RT-N56U has been the fastest router tested at smallnetbuilder....at over 800 megs throughput.The new RT-66U has a 600MHz processor, and 1 gig of RAM. State table size (concurrent sessions) at over 300,000.
Supposed to be based on the Broadcom chipset..so it'll probably support DD-WRT...but to be honest, I saw some screenies of the Asus firmware for this unit...and holy crap what cool features.url...
Having some issues with a vpn between two of my locations. Both edge devices are ASA's, and the tunnel is an IPSEC tunnel. Both MTU's are set to 1500 both on inside and outside. (provider mtu setting request is 1514, and both ASA's will be changed out soon.) Unfortunately, some exchange/kerberos auth issues are causing me a problem in the remote site. I perform the tests that microsoft recommends using a length of 1472 on packet ping size, and do not fragment flag (1406 is the largest packet I can push across the vpn) . I know part of this is due to the extra overhead that ipsec places on the connection.
I want to refrain from putting the black hole registry workaround on all of the PC's in this remote location.I've also seen some discussion about manually setting the TCPMSS value down to 1300 on most ASA's.
Just discovered I can change the focus on a DCS-920 by adjusting the black ring around the lens. It can be focused from very close, just inches, to infinity. I don't see this in any of the DLink documentation.
View 2 Replies View RelatedWe have a customer that has a fiber rum between 2 building. They want to have 2 seperate fibers active that terminate into the same switch on each end. (redundancy).
In building A they have an extreme networks black diamond switch that does not support STP.In bulding B they have a Cisco 4507.
We will ahve to use a layer 3 routed connection due to the fact their switch in building A does not support STP.Our tech does not want to use static route becuase he does not want to setup IP SLA for the redundant connection.
Will RIPv2 work for this scenario and failover to the other fiber if needed? The hop count is the same for each fiber path..
