Prevent Neighbour From Using Wifi?
Sep 2, 2011
I have high speed wifi at home and the wifi is WPA-PSK protected. My neighbour will be coming to my home to work with me and I will be keying my wifi password into his Windows XP laptop for him to access my wifi.
This is one time access only, after that he is not allowed to access my wifi. To prevent him from accessing my wifi, I will have to delete the password that I keyed into his laptop.
Where do I find this wifi password in the Windows XP? What folder and what filename?

My IPTV connection works fine so far but as soon as I start watching TV I can't use my WiFi connection anymore. My router is an "Alice Modem 1121" (SIEMENS S1621-Z220-A) with 4 LAN ports and a WiFi interface (4th LAN port provides the IPTV). It is directly connected by wire to my PC's ethernet card for the IPTV and the internet is provided via the WiFi. When I activate the LAN connection the WiFi and internet connction stays up and requests can be sent but nothing returns anymore. Another device (iPod) has no problems with accessing the internet while IPTV is in use. I also have a Netgear WNR1000v3 router which I tried to use as AP instead but it's exactly the same problem. Unlucky the Netgear router is not supported to use dd-wrt firmware yet (I've found a step by step guide to prevent multicast floods with dd-wrt/ebtables). But maybe the Alice Modem can handle this problem on its own. I read some stuff about VLANs and splitting them but I have no clue how that would look like.
The "nas_0_1_34" is for the IPTV.

I have a problem where I have 3845 router and c3845-advsecurityk9-mz.124-24.T5.bin dis is the IOS running on it and there's a back up BRI interface for the serial. Now if my serial link goes it normally goes to my BRI, once we had a time where the BRI was also down and when we restored back the Serial link we were still not able to reach the other side. We are using OSPF routing to reach the destination. When this happens and when we reboot this router we are able to reach the destination. sometimes we are able to reach it when we remove ospf and use static and now if we put back the ospf routing the link comes back, this happens again and again.

I share my internet connection with my roommate who is very tech savvy. I found out yesterday that he has been hacking into my gmail account and reading my emails. I didn't think it was quite possible and I'm very surprised. He manages the internet connection and has full access/control over it.what can I do to prevent him from accessing my information?

We have 9 WLCs around a corporate network. Each of the WLCs was in the same mobility group for failover purposes, and to permit APs to reconnect back to their primary WLC in the event of a failover.
However one of the sites has now been sold and pending separation of the LAN infrastructure the APs need to be isolated and prevented from associating with any WLC other than their primary (on site). From our experience once the APs know about other WLCs they retain this list in NVRAM even if the secondary WLC is removed from the configuration they will still associate with one of the known APs if possible (Cisco document this). WLC v 8.1.185.

I often have to change switch ports to different VLANs. Regardless of whether I find the ports myself or if someone tells me what the ports are, I'll always perform additional verification steps to make sure that the port I'm changing doesn't connect to a switch, a router, a server, or something else that's equally important. But mistakes happen, and I have accidentally changed the wrong port to a different VLAN, thereby disconnecting the end node.
Is there a way to configure a port so that it will not allow you to change its VLAN (or make any configuration changes to it)? I'm imaging a command that when applied to a port would not allow you to make config changes to the port until you remove that command from that port, at which point you'll be able to change its VLAN, shut it, etc. If there isn't such capability, what strategy do you use to minimize the possibility of accidentally changing trunks, routed ports, or important access ports to different VLANs (other than labeling and verify)?

I've tried a few things to get around this, some kids where I work keep changing the wallpaper, sometimes to quite disgusting things. Since groups of them all use the same login with roaming profiles, everyone gets to look and laugh at the annoying wallpaper.
I've tried enabling active desktop local policy and preventing users changing wallpaper but as far as I could tell active desktop didn't even come on, I refereshed the policy.
Does anyone know a good efficient way of simply setting a wallpaper for all users in an ad ou and preventing them changing it? I've got rid of all ways to set a desktop wallpaper apart from the right click menu on an image which has the "set as backgound" option, that's what they are using to do it.
I don't really mind how it's done, could be a registry hack to remove that option from the right click context menu when clicking on an image, I could then deploy it with group policy.

My wife is moving into an apartment complex for school and she has a Brother HL-2270DW printer. Since she only has a laptop and moves around the apartment, I would like to use the wireless on the printer. Unfortunately, the internet for the building is just through wireless APs. I have the printer installed on the network, but my concern is that anyone can just search for network printers and install it. While printing on it won't be useful for them, it could be a good way to waste her paper/toner. Is there a way to prevent users from installing it without being able to change the router settings? I did not see any option in the web configuration.

I am having some trouble understanding extended control lists. I am trying to prevent a certain host on LAN1 from accessing a server on LAN2, while still allowing the host access to the rest of LAN2.This is what I thought the command should be:
access-list 100 deny ip 175.16.1.2 0.0.0.0 175.17.2.2 0.0.0.0
My understanding was that:
Green = source & mask
Red = destination & mask
However this seems to stop all my other hosts on LAN1 from pinging the server also.

Just bought myself an 825. I've got it set up and working, but how do I prevent wireless users from accessing the setup pages for the router?
I only wish wired access to the setup pages. I'm used to doing this on my old linksys, but can't find the setting on the new router.

I'm wondering if anyone knows to set up the switch so that when I'm connecting via SSH, the switch doesn't prompt for a username if I supply one in the initial connect request? For example, we usually connect by typing something like the following at a command prompt:
ssh johndoe@10.10.10.10
Then the switch would prompt for a password. I've tried this on the Cisco SF302 but it still prompts for a username, and then the password.

We have a couple of switches with a L3 Vlan 238 interface which runs PIM SM and OSPF, and HSRP. We have connected to this same segment telemetry processors which have raw socket interfaces configured - which means it picks up all IP packets which hit the interface and forwards them along.So we dont want the processor to recevie any of the 224.x.x.x switch housekeeping traffic? is there anyway to prevent that ?

At the core of my network I have two Nexus 5548's with the routing/L3 daughter installed. They have a default route that points to my ASA 5520 for Internet access. I have configured a VLAN that I do not want to have access to the Internet. What is the best way of preventing this access? ACL on the Nexus or Firewall rules on the ASA?

Dropped VPN connections.I experienced a similar issue a few years ago with my LinkSys WRT54G router with dropped connections to my corporate network using the Cisco VPN Client. To make a long story short the problem was the result of the following:
1. The default ""Client Lease Time" on LinkSys routers is 0 which means 1 day or 24 hours.
2. By DHCP Protocol definition, DHCP clients must renew the DHCP client IP address lease at the 1/2 life cycle of the lease (12 hours if using the router's default setting). This is deadly for VPN clients as the short period of time when the client IP address is no longer valid, the VPN client considers this a loss of network connection. The LinkSys E-series routers further aggravate the situation by randomly assigning new IP addresses to DHCP clients instead of reassigning the client's previous IP address and tends to favor higher host IP addresses in the defined range.
Suggestions to prevent lost VPN client connections:
1. Change the "Client Lease Time" on the router to 8640 minutes (6 days 00:00:00).
2. Prior to establishing a VPN client connection, use the Windows Command Prompt to issue the "ipconfig /renew"
command to obtain a new IP address from the router that will be good for 3 days (72 hours).
3. Configure your E-series router to use the <DHCP Reservation> option to pre-assign IP addresses to your systems making sure they are outside the range of the dynamically assigned DHCP addresses. Using default settings,these would be in the range of 192.168.1.2 thru 192.168.1.99 as the router starts at 192.168.1.100 thru 192.168.1.149.

I want to know what is the best way to black traffic inside the same VLAN, this VLAN is a user VLAN, it means that I am talking about access layer.I wanted to use private vlan, but C2960S doesn't support this feature. Any other way to prevent any to any traffic in the user vlan, this vlan only have to speak at the Layer 3.

I want to configure my ACE so that if a probe fails, it fails over to the backup rserver, BUT it won't failback to the primary rserver until manual intervention is complete. The problem is we don't want an rserver to fail and failover to secondary, then failback to primary, repeat... (flip-flopping). I want to be able to have time to get on the server and find out what may have caused the probes to fail before it fails back.
