What if packet size cannot be represented as a value divisible by 8?
Suppose a packet contains 23 bytes of data, and the MTU of the network is 1024 bytes. We have to make sure the data is divisible by 8. But in this case, that is not possible since if the data is represented as 24 bytes,there will be an extra byte (where do we get it from?) and if the data is...

Java method to reset a packets time to live
I was told that there is a JAVA method to reset a packets time to live. Given that a packet being accepted by a machine that had java on it would create a new header anyway, is the point to increase the TTL? The person made the statement that these packets roam the Internet for years. am I...

Obfuscation of destination IP address
A self proclaimed security architect told me that there were hacking attacks where the hacker "obfuscated" the destination IP address to confuse the router into forwarding the packet out all of its interfaces and subsiquently the packet would live forever. In my limited knowledge I was a bit...

Inbound traffic is coming from router IP, not internet IP. Why?
Hello, thank you for your time. I have recently noticed a strange occurence going on with inbound traffic. The other day, I helped my friend set up his network. icmp ping was good. while sniffing, I first noticed inbound tcp traffic to me was not coming from my friend's IP address, but coming from...

Coding for packet header duplication
I want to know, how to filter packet header duplication. Packets may travel in sequentially over the internet. If the headers duplicate, the traffic will delay. so, I want to block the site that header duplicated. It may be Perl, C++ or other programming languages.
