Hitting the Enter key in your text editor starts a new line. If you type a long paragraph in a text editor and never hit the Enter key, then that paragraph is all on one line. Your text editor may display the paragraph as being on multiple screen lines (a feature called word-wrap), but that's a...

My man page says that recv may discard excess bytes depending on the type of socket. In other words, it'll probably discard excess bytes if you use it on a datagram socket, but for a stream socket, it shouldn't discard a thing.

From the "Environment Variables" section of my GNU grep (2.5.3) man page: POSIXLY_CORRECT If set, grep behaves as POSIX.2 requires; otherwise, grep behaves more like other GNU programs. POSIX.2 requires that options that follow file...

Actually, upon reading the documentation, that does not seem to be able to filter based on DNS name of the connecting IP. It just lets you filter based on IP, and gives you the ability to do a one-time reverse DNS lookup to find that IP. So does IIS have the ability to filter based on DNS name...

This is a nice resource for when you know how to do something on one Unix variant and want to find an equivalent for another: http://www.bhami.com/rosetta.html

The fuser command can be used for the same thing with slightly different syntax: fuser 22/tcp Try the -v option, too.

That sounds about right. Thanks!

Apache has "Allow From" and "Deny From" directives that can control access based on the DNS of a connecting IP (found by a reverse lookup). I was wondering if IIS has an equivalent to this capability.

Those aren't the file's permissions; that's a symlink, and symlinks always show up with 0777 permissions. You're looking for the permissions on the file it's pointing to (/opt/K/SCO/tcp/6.0.0Ni/usr/bin/rlogin, if that's not also a symlink).

Also, netstat has a -p option: -p, --program Show the PID and name of the program to which each socket belongs.

To address the underlying problem here, I'd suggest you look into using a directory service like NIS+ or LDAP.

For a simple project, you can get away with listing both source files on the command line: $ g++ gcd.cpp gcd-tester.cpp -o gcd-tester However, the correct way (especially on larger projects) is to compile each source file into an object file (ending with .o) using the -c option, then link the...

Most distributions have package managers that work with binary packages. You should just be able to download and install a gcc package without compiling. Then, you can use it to compile the other one if you really need to. What distribution is your Web server running? If it's Debian-based...

Is the wcsdup declaration #ifdefed out? With what? I'll bet you need to do: #define _GNU_SOURCE #include <wchar.h> to make the declaration visible to your code.

The block takes two arguments: a "current value" (memo), and the next item in the sequence (obj). The block specifies an operation that is to be performed on its arguments (the current value and the next item), resulting in a new value. The block is called for each element in the sequence. The...
