is there a way to protect my computer from someone sniffing in my LAN
i mean i couldnt figure out a way since he doesnt need any access to my computer , i assume you know about sniffing !
so how can i know if someone is sniffing and how to prevent my sent info to be taken !
 
LAN? isnt lan wired? wan is wireless i think. if hes sniffing your lan go unplug his cable. if its wireless set up some encryption and restart your router
 
yes LAN is wired... what is the problem with that ?
how can i unplug him if i dont know or can't prove that he is sniffing !
and i can't setup some encryption when i use my lap because the router is not mine
it's usually a hot spot in a mall or hotel ! it's not encrypted
 
well if he is stealing your LAN conection than he has to be plugged into the network. or do you mean he is looking at your computer?
 
Anytime you’re using somebody else internet/network connection, you always taking a chance of somebody peering in and looking at what traffic is coming from your machine. You best bet here is to turn off file and printer sharing and disable NetBIOS temporarily until you return to your home and or private network. This way the will not be able to see your computers NetBIOS name and they can't view any of your shares that might be in place.
 
guys i dont think you understand the problem well
this IS my home network
he is my neighbor
i already know a way to prevent accessing my computer
i'm talkin about sniffing here
man in the middle attack

if you dont know what is sniffing then you can't answer my question
thanks for trying to help though
 
If you on a wired LAN, I don't understand your concern here :confused:.

The only time sniffing would be a problem is if you LAN was wireless and he was sniffing the wireless traffic. If you and he are on two different wired LANs and are within you own homes going out to your own ISPs or even the same ISP for that matter with nothing else in-between that could possible lead to somebody intercepting your traffic, then you have nothing to worry about. The only way he could possible capture your traffic is if he hacked one of your machines or he somehow broke into your home and started capturing the traffic from your LANs gateway or from a hub located on the network (if you use a hub). But I'd think your realize somebody was in your house capturing your traffic for no apparent reason.

LAN Local Area Network
WAN Wide Area Network (ISP)
WLAN Wireless Local Area Network

duh.......!
and FYI
i'm connected to a switch with that guy and the switch is connected to a router
sniffing in LAN is hijacking IP traffic between hosts this is called APR
ARP Poison Routing
i don't wanna get into this
i'm the one who is asking here

so please stop posting useless posts
i already know when i'm at risk or not i used to study MCSE
my question is clear
Is there a way to stop him from sniffing the traffic between me and the router ?

Thanks

Well since it would have been nice to know at the beginning of this thread the situation at hand, I and the other user that contributed to this post would have been more able to assist you.

If you want to prevent ARP poisoning, you would have to turn of both ARP and DHCP all together, assign static IPs to all the machines on the network, create a static ARP table on every node (with a static entry for every other node), stop the switch(es) from passing ARP traffic and or stop the machines from accepting ARP traffic.

Note: This will most likely make your LAN unusable, but will prevent ARP poisoning.


There is no fool proof way of preventing ARP attacks.

i want to prevent sniffing my machine traffic only not all nodes

DHCP is turned off already

could you please say the other stuff in more details !

You sure do have a lot of attitude for a person who is asking a question that was not clear until the end of the thread. Have you ever done sniffing on a network? Also, saying that you used to study MCSE doesnt make a difference to anyone here. It's almost a laughable thing anyway. If you dislike what people are saying then try searching for it on Google.
