We've got Workgroup LAN at our office and the Server is configured by the OS “Windows Server 2008 R2”. Most of the users use OS Windows XP-Service Pack-2. Now, I want to see the Internet surfing status/activities done by any particular user/users at any time from the Server. You know that, some people enter into restricted sites which impose severe negative impact on the network. If I could trace from the Server any user of doing this, I shall block his Internet connection from the Server.

I have WCS 7.0.172.0 where as i have very frequent alert about DoS : CTS flood In channel 60, the system has detected 212 CTS frames in the last minute, which matches the traffic pattern of the form of denial-of-service attack, CTS (Clear-To-Send) attack. A wireless denial-of-service attacker may suspend the wireless media for communication by taking advantage of the privilege of CTS frame to reserve RF medium for transmission. By transmitting back to back CTS frames, an attacker can force other wireless devices sharing the RF medium to hold back its transmission until the attacker stops transmitting the CTS frames. The system detects the abuse of CTS frames for denial-of-service attack.

I am attempting to block all FTP traffic on port 21 from the servers in my network, and only allow FTP from one server to go out.
I have created the following ACL
access-list 101 Permit ip any any
access-list 101 Permit 21 1.1.1.1 0.0.0.0 any
access-list 101 Deny 21 any any
and have applied it to my truck VPN that goes up to my firewall
int Vlanxxx
ip access-group 101 out
But when i test ftp is still allowed by all servers.

I can't seem to find any info on how to configure 2 DHCP server pools on a C3750, to use with 2 user vlans. The purpose is that users in vlan 1 should get an IP address from DHCP server1, and users in vlan 2 should get an IP address from DHCP server2. Both DHCP servers are configured in a stack of C3750 switches, which acts a a L2 switch.

There is a unicast flood on 3750 killing slow modem links. How to determine source MAC address of flooder? Is there a rate limit feature for it?
I know how to block it completely on port-level, but it breaks normal network operation. (when port goes down for some reason, it's learned MACs got flushed and since other hosts know MACs, they keep flooding untill their arp caches expire).

I'm not entirely sure what's going on. I run 4 computers on this network, 2 Windows Xp, 1 Windows 7, and 1 Linux. All of which cannot access AIM, Gchat, and Minecraft(lol). I have no idea what would cause this, I run DD-WRT on my router(Linksys WRT-54G). I've checked all ports and I don't have anything blocked. I seriously need to fix this because I use AIM for my work. I can't even get into AIM Express which is web-based(tells me to check my network connection.

I have time warner cable as my ISP, and have a netgear wireless modem hooked up to the only computer in house, in my living room, but I would like to have internet access in my room as well (where my rig will be). What do I need to get? I was thinking of getting a wireless network adapter PCI card, but am a bit concerned that I will then have to deal with laggy connections while online gaming.

I have a netgear wireless modem router in an upstairs bedroom/study. My problem is that I can connect my son's windows 7 laptop wirelessly in any of the upstairs rooms with a good download speed (around 8mbps) except for his bedroom in which the download speed suddenly drops to 400-600kbps. I can sit on the landing connecting at 8mbps, then move into his doorway and it drops to around 3mbps and then a couple of feet further into the room and it's only 500kbps.
I've tried turning off all other electrical appliances in his room but it makes no difference. Obviously something is affecting the download speed dramatically but I'm at a loss as to what it can be. The signal strength seems fine.

recently I have been using my laptop downstairs where the router is in the same room, and now, when I attempt to connect to the network in my bedroom it connects for maybe a few seconds and indicates an average connection and I can also see other available networks before suddenly all connectivity is lost, I can't even see other available networks. Previously I would be able to get strong signal in my bedroom and I was able to use the internet without any fault.I have tested a family member's laptop in my bedroom, and theirs seems to be working just fine in my room. I can only use my laptop downstairs now and I need to know if this is a fault with my laptop's network adapter or if it's a problem with connection between my laptop and the router.

I'm staying at a friend's place and can only access the internet when I'm in the same room as the router.When out of the room my computer detects the network at two bars of strength but after a short time denies me access, when I run the network troubleshooter it says that it cannot detect the proxy settings.My friend can connect fine to the network from anywhere in the house and I can connect to my home network and my school network with no problems.Both of us are running Dell Laptops with Windows 7.My card is a Dell Wireless 1510.The router uses WPA2 encryption.why I can't connect?

I am trying to move one of my PCs to a different room where CTA5 will be impossible to connect, and decided to go with a wireless adapter. My previous wifi experience is limited to built in adapters in laptops (Dell, HP, Asus) and smartphones (HTC, samsung).I use Win 7 64bit and a 2wire gateway (att dsl).None of these devices ever gave me trouble, even when being rooms away (signal quality would drop, but no disconnects).My first try was with a Roseville 150Mbit USB adapter. I let my Windows install the driver, it worked and connected just fine with good speeds. But every so often it would disconnect (resetting my gateway in the process). This has never happened before with any of my other wireless devices, so I replaced the adpter with another. This time it was a TP-link brand adapter. Again I let windows find a driver, everything worked, good speeds, but again I got random disconnects. I than downloaded software from TP-link and installed drivers that way, but nothing changed.The disconnects aren't frequent ( 2-3 in an hour) and are short in duration, but since I will use the machine for online gaming, this will not work.

I have a DIR-615 D4 (Original firmware V1.00VG), I tried to install DD-WRT using all the guides online and here, but no matter what i do, the router does not seem to successfully complete the flash?
- successfully entered emergency room
- uploaded the bin file
- power light turns off (but link to machine light still on)
- left it for a good 10 mins to be sure, and still no life out of it
- power cycled and router goes back to emergency room
So i then tried to revert back to the V1.00VG;
- uploaded bin file
- power light stops flashing and stays on solidly (link to machine still green)
- left it for a good 10 mins to be sure, and still no life out of it
- power cycled and router goes back to emergency room

My question has to do with the low signal strength of my dir-655. I have it set up in the second bedroom of my apartment. When I am sitting in my living room (about 30 feet away) it's really hard to pull in a signal of more than one bar on my phone, or two bars on my wife's kindle fire and will often drop the signal all together. But, if I search for networks, tons of other routers come up with excellent signal strength from our neighbors. Is there something I need to know about expanding the signal strength?
