On the Internet, the user' s domain name and IP address areone-to-one correspondence. But the virtual dial-up access tothe Internet, resulting in a dynamic IP address. This has causedtrouble for computer enthusiasts who don' t have much money toapply for domain names. The previous period, due to the authorof the region' s ADSL instead of virtual dial-up, the troublealso troubled the author for a while. After many debugging,finally realized the dynamic IP address domain name automaticpointing under Linux. Now we will record it and share it withyou:

Before thehttp://www.deerf ield.com/download/dns2go/linux/index.htm isa server for a free domain name, put the dns2go in the/etc/rc.d/rc. local, the boot fixed free domain name. But ADSLto virtual dial-up way, there is no fixed IP address, startdns2go is very troublesome, first use the ifconfig command tofind the ppp0 IP, and thenmodify the IP under/etc/dns2go. conf,and then can start dns2go. It' s inconvenient to use manualoperation every time. It can not be started automaticallywithout anyone' s intervention. Write a C program to solve theproblem, in cases of all procedures are assumed installed inthe /usr/local/bin/, a program written in shell to call the Cprogram, the directory containing xnbh (shell program) , trans(Executive C program compiled) , outfile (intermediatetemporary files) , pppoe.txt (intermediate) , dns2go. conf(typical the configuration file)

The shell program for xnbh is as follows:

Adsl-start# starts the virtual dialer for adls,

The ifconfig ppp0 |grep -v "Link" >/usr/local/bin/pppoe.txt#produces the pppoe. txt file in the directory

The /usr/local/bin/trans# invokes the C program to extract theIP value in the file pppoe.txt, and then replaces the IP valuein the dns2go.conf to produce the intermediate file outfileCP/etc/dns2go. conf/etc/dns2go.confold#backup the originaldns2go. conf file

CP /usr/local/bin/outfile /etc/dns2go. conf # after replacingthe dns2go.conf file

Nohup /usr/local/bin/dns2go >/var/tmp/dns2go. log 2>&1 &#start fixed domain

After executing the second sentence in xnbh, the followingpppoe.txt is generated:

INET addr:218.65.217. 109 P-t-P: 172.0.0. 1

Mask:255.255.255.255

UP, POI NTOPOI NT, RUNNING, NOARP, MULT I CAS T, MTU: 1492, Met r i c: 1RX, packet s:26, errors:0, dropped:0, overruns:0, frame:0TX, packets:27, errors:0, dropped:0, overruns:0, carrier:0Collisions:0 txqueuelen:3

RX bytes:1400 (1.3 Kb) TX bytes:1358 (1.3 Kb)The trans. c program is as follows:

#include <stdio.h>

#include <ctype.h>

(ma i n)

{

F ILE, *fp, *bp, *out;

Int i=0;

Int j;char ip [16] ;char dip [16] ;char na [] = "address =";char inip [24] ;char readln [255] ;char readlnn [255] ;

fp = fopen ("/ usr / local / bin / pppoe.txt", "r") ;if (fgets (readln, 255, fp) ! = = null)

{ (i = 0; i < 16; i + +) ip = readln [20 + in] ;}in = 0;for (i = 0; i < 16; i + +)

{if (ip! = ' ' )

{dip = ip; printf ("ip% d =% c% n" in, ip) ; }else {j = i; printf ("j =% d", j) ; } }for (i = 0; i < = j; i + +) dip = ip;dip [j] = '\ 0' ;printf ("a =% s \ n", dip) ;f c l o s e (fp) ;strcpy (inip, na) ;printf ("inip =% s \ n", inip) ;strcat (inip, dip) ;

printf ("inip =% s \ n", inip) ;fp = fopen ("/ usr / local / bin / dns2go. conf", "r") ;out = fopen ("/ usr / local / outfile", "w") ;while ( ! feof (fp)) {if (fgets (readlnn, 255, fp) ! = = null)i f (strncmp ("addres s = aaa.bbb.ccc.ddd", readlnn, 15)) fputs(readlnn, out) ;else fputs (inip, out) ; }f c l o s e (fp) ;fclose (out) ;

}

在linux下用gcc –o trans trans.c编译通过产生文件trans,dns2go. conf的配vchgob #:

#

# simple configuration file for dns2go linux client

#

# for more information refer to the dns2go.conf manual page#

# global directives

#

# dns2go serverserver = discovery.dns2go.com

# key (required, case sensitive)key = aaaaaa - bbbbbb - ccccccc - ddddd (此项为申请的激活码)# log file (optional, default: syslog)

# log = / var / log / dns2go.txt

# send debug outputs two stdoutdebug

# number of connection attempts (optional, default: 8)# retries = 8

# rate two send heartbeats (in minutes) (optional, default: 0= automati c)

# heartbeat rate = 0

#

# domain directives

#

# fully qualified domain name (required)doma in = xxxxx.dnsgo.com (此项填写固定免费域名)

# static ip address (optional, default: external ip address)address = aaa.bbb.ccc.ddd (此项为假设ip)

# online www alias redirection: choose one of the following:# (optional, default: www. alias resolves two domain ip)# www redirect - url = http: / /. . .

# www redirect gate = 8080

# offline redirect option: choose one of the following# (optional, default: offline status page)

# offline - url = http: / /. . .

# offline - ip = 0.0.0.0

以上xnbh程序若加入/ etc / rc.d / rc. local /中则可以启动时自动启动固定免费域名,

此时你可以启动的apache, ftp, telnet等都可以用此免费域名了,出门在外的朋友可以

很方便找到自己的服务器,熟悉shell的朋友也可以用shell完成c程序的功能, 以上的

程序在redhat7.2上顺利通过.david
