This three-part series on AIX® networking focuses on the challenges of optimizing network performance. In the first installment, you’ll review some best practices for network configuration, and utilize those practices for efficient monitoring of your hardware by taking advantage of network tools such as netstat, netpmon, entstat, and nmon. You'll also examine certain tools used to look at your interfaces to see how to configure them.
Traditionally, Unix/Linux/POSIX filenames can be almost any sequence of bytes, and their meaning is unassigned. The only real rules are that "/" is always the directory separator, and that filenames can't contain byte 0 (because this is the terminator). Although this is flexible, this creates many unnecessary problems. In particular, this lack of limitations makes it unnecessarily difficult to write correct programs (enabling many security flaws), makes it impossible to consistently and accurately display filenames, causes portability problems, and confuses users. more ....
