《 UNIX网络编程》源码的使用

学习编程这东西，看代码，改代码，运行代码这样才能学到实际东西！本书说在www.unpbook.com可以获取源码，不过打不开！所以google

unpv13e.tar.gz

并在网络上找到了：源码：http://code.google.com/p/stid/downloads/detail?name=unpv13e.tar.gz&can=2&q=

现在就是使用的问题了！

关于在windows下的问题

既然是unix网络编程，直接在windows下运行当然是行不通的！（问：那还学这个干嘛！？？你说呢，我们学的是思想和方法，window网络编程其实差异不大）

不过在windows下装个UNIX模拟器cygwin貌似是一个不错的选择！也有人用这个模拟器搭建UNIX网络编程平台，不过对初学者有一定难度！（cygwin是个好东西呀！）

关于在Linux 下的使用问题

Linux也是UNIX,当然没问题！现在说明如何使用书本源码unpv13e.tar.gz的问题。

首先，解压源码,这里是解压到当前目录:acer@ubuntu:~$ tar -xvf unpv13e.tar.gz

其后，建议去阅读解压后目录unpv13e下的README文档！

README文档内容如下：（ubuntu下执行红色部分即可）

QUICK AND DIRTY

===============

Execute the following from the src/ directory:

    ./configure    # try to figure out all implementation differences

    cd lib         # build the basic library that all programs need

    make           # use "gmake" everywhere on BSD/OS systems

    cd ../libfree  # continue building the basic library

    make

    cd ../libroute # only if your system supports .4BSD style routing sockets

    make           # only if your system supports .4BSD style routing sockets

    cd ../libxti   # only if your system supports XTI

    make           # only if your system supports XTI

    cd ../intro    # build and test a basic client program

    make daytimetcpcli

    ./daytimetcpcli 127.0.0.1

If all that works, you're all set to start compiling individual programs.

Notice that all the source code assumes tabs every  columns, not .

MORE DETAILS

============

.  If you need to make any changes to the "unp.h" header, notice that it

    is a hard link in each directory, so you only need to change it once.

.  Go into the "lib/" directory and type "make".  This builds the library

    "libunp.a" that is required by almost all of the programs.  There may

    be compiler warnings (see NOTES below).  This step is where you'll find

    all of your system's dependencies, and you must just update your cf/

    files from step , rerun "config" and do this step again.

.  Go into the "libfree/" directory and type "make".  This adds to the

    "libunp.a" library.  The files in this directory do not #include

    the "unp.h" header, as people may want to use these functions

    independent of the book's examples.

.  Once the library is made from steps  and , you can then go into any

    of the source code directories and make whatever program you are

    interested in.  Note that the horizontal rules at the beginning and

    end of each program listing in the book contain the directory name and

    filename.

    BEWARE: Not all programs in each directory will compile on all systems

    (e.g., the file src/advio/recvfromflags.c will not compile unless your

    system supports the IP_RECVDSTADDR socket option).  Also, not all files

    in each directory are included in the book.  Beware of any files with

    "test" in the filename: they are probably a quick test program that I

    wrote to check something, and may or may not work.

NOTES

-----

- Many systems do not have correct function prototypes for the socket

  functions, and this can cause many warnings during compilation.

  For example, Solaris 2.5 omits the "const" from the 2nd argument

  to connect().  Lots of systems use "int" for the length of socket

  address structures, while Posix.1g specifies "size_t".  Lots of

  systems still have the pointer argument to [sg]etsockopt() as a

  "char *" instead of a "void *", and this also causes warnings.

- SunOS 4.1.x: If you are using Sun's acc compiler, you need to run

  the configure program as

        CC=acc CFLAGS=-w CPPFLAGS=-w ./configure

  Failure to do this results in numerous system headers (<sys/sockio.h>)

  not being found during configuration, causing compile errors later.

- If your system supports IPv6 and you want to run the examples in the

  book using hostnames, you must install the latest BIND release.  You

  can get it from ftp://ftp.vix.com/pub/bind/release.  All you need from

  this release is a resolver library that you should then add to the

  LDLIBS and LDLIBS_THREADS lines.

- IPv6 support is still in its infancy.  There may be differences

  between the IPv6 sockets API specifications and what the vendor

  provides.  This may require hand tweaking, but should get better

  over time.

- If your system supports an older draft of the Posix pthreads standard,

  but configure detects the support of pthreads, you will have to disable

  this by hand.  Digital Unix V3.2C has this problem, for example, as it

  supports draft , not the final draft.

  To fix this, remove wrappthread.o from LIB_OBJS in "Make.defines" and

  don't try to build and run any of the threads programs.

COMMON DIFFERENCES

------------------

These are the common differences that I see in various headers that are

not "yet" at the level of Posix.1g or X/Open XNS Issue .

- getsockopt() and setsockopt(): 5th argument is not correct type.

- t_bind(): second argument is missing "const".

- t_connect(): second argument is missing "const".

- t_open(): first argument is missing "const".

- t_optmsmg(): second argument is missing "const".

- If your <xti.h> defines the members of the t_opthdr{} as longs,

  instead of t_uscalar_t, some of the printf formats of these value

  might generate warnings from your compiler, since you are printing

  a long without a corresponding long format specifier.

注意：以后我们都用make编译源代码

最后运行：./daytimetcpcli 127.0.0.1如下

acer@ubuntu:~/jwt/unpv13e/intro$ ./daytimetcpcli 127.0.0.1
connect error: Connection refused

发现报错：connect error: Connection refused

这种情况说明服务器没有启动daytime服务！那Ubuntu如何启动，daytime服务呢？

Ubuntu启动daytime服务

1. sudo apt-get install xinetd

2. sudo vi /etc/xinetd.d/daytime, 把 disable = yes to no

3. sudo /etc/init.d/xinetd restart

在运行 ./daytimetcpcli 127.0.0.1

出现结果！！
