If you put computers with IP addresses that should be on separate subnets on a local network with each other, they won't be able to communicate. They'll try to send packets to each other through a router that can't forward them correctly. A symptom of this problem is a computer that...

and in order to stop them you need to understand and correct the weaknesses in TCP/IP or higher-level protocols that they will attempt to exploit. In other words, know what your enemy knows.
However, sending all messages to a single file makes it difficult to follow what is occurring in a single application over many hours. In addition, sending all messages to a single file does not exploit the multithreaded design of the syslogd, because each individual destination is assigned a ...
2 IBM z/OS V2R1 CS TCP/IP Implementation Volume 3: High Availability, Scalability, and Performance Address Resolution Protocol (ARP) takeover ARP enables your system to transparently exploit redundant physical interfaces without implementing a dynamic routing protocol in your mainframe. See Chapter 3...
FACK allows the sender to continue to send packets into the network during this period, in an effort to allow the sender to maintain an accurate view of the ACK clock. FACK also provides an ability to set the number of SACK blocks that specify a missing segment before re- sending the ...
but the principle remains the same—the routing table explicitly lists all of the networks behind the gateway and where the next closest (internal) gateway is for those internal networks, and the routing table lists a default gateway entry to send packets to that the gateway otherwise doesn't ...
