I bought a linux host and saw on the Internet that my host can be used to build my own vpn server. The key is that I can still roll over the wall. I feel pretty good. I want to build a linux host system.Centos6.5 It took me a long time to build a vpn above. This article focuses onCentosBuild the pptpd service on 6.5.

1. install ppp

Run the command: yum install ppp

2. install pptp

32 bit rpm-ivhhttp: // acelnmp.googlecode.com/files/pptpd-1.3.4-1.rhel5.1.i386.rpm
64 bit rpm-ivhhttp: // acelnmp.googlecode.com/files/pptpd-1.3.4-1.rhel5.1.x86_64.rpm

The author's system is 32-bit, so execute the command: rpm-ivhhttp: // acelnmp.googlecode.com/files/pptpd-1.3.4-1.rhel5.1.i386.rpm

The command line window prompts a problem.

Error: Failed dependencies:
Ppp = 2.4.4 is needed by pptpd-1.3.4-1.rhel5.1.i386

It indicates that pptp requires the ppp Version 2.4.4, and I have installed the ppp version 2.4.5, so I decided to uninstall the latest ppp, re-download and install Version 2.4.4, and run the command: yumremove ppp

Download ppp 2.4.4 ftp://ftp.muug.mb.ca/mirror/centos/5.9/ OS /i386/CentOS/ppp-2.4.4-2.el5.i386.rpm

Here to introduce a very good site, http://rpm.pbone.net, I have a lot of rpm packages all under this site. then install the downloaded ppp, execute the command: rpm-ivh ppp-2.4.4-2.el5.i386.rpm, then another problem occurs, the following prompt appears:

Error: Failed dependencies:
Libpcap. so.0.9.4 is needed by ppp-2.4.4-2.el5.i386

This is really tough. it means ppp2.4.4 depends on libpcap. so.0.9.4 and runs the command rpm-qa | greplibpcap. The result is displayed:

Libpcap-1.0.0-6.20091201git117cb5.el6.i686, indicating that the current libcap version is 1.0, and ppp2.4.4 is the need for 0.9. no way to only on the http://rpm.pbone.net this site is to download libpcap. so.0.9.4, and then uninstall the libpcap-1.0.0 version. execute the command:

Wget ftp://ftp.pbone.net/mirror/archive.fedoraproject.org/fedora/linux/core/6/i386/ OS /Fedora/RPMS/libpcap-0.9.4-8.1.i386.rpm

Run the command to uninstall libpcap: rpm-e libpcap. the following error message is displayed:

Error: Failed dependencies:
Libpcap. so.1 is needed by (installed)Tcpdump-14: 4. 0.0-3.20090921gitdf3cb4.2.el6.i686

It indicates that the libpcap package is still dependent on tcpdump. Therefore, you can only uninstall the libpcap package using yum and run the command: yum remove libpcap.

Install libpcap. so.0.9.4 and run the command: rpm-ivh libpcap-0.9.4-8.1.i386.rpm

Install ppp2.4.4, run the command: rpm-ivhppp-2.4.4-2.el5.i386.rpm, finally you can successfully install the ppp, then you can install pptp, re-execute our above command:

Rpm-ivhhttp: // acelnmp.googlecode.com/files/pptpd-1.3.4-1.rhel5.1.i386.rpm

3. configure pptp

Vi/etc/pptpd. conf: # localip 192.168.0.1 # remoteip192.168.0.234-238,192.168 .0.245: localip 192.168.0.1 remoteip192.168.0.234-238,192.168 .0.245 the localip here refers to the virtual ip address of your vpn server, remoteip is the virtual ipvim/etc/ppp/options.ppt pd you used to connect your vpn server to find # ms-dns 10.0.0.1 # ms-dns 10.0.0.2 changed to ms-dns 8.8.8.8 ms-dns 8.8.4.4 add a pptp account: vim/etc/ppp/chap-secrets # Secrets for authentication using CHAP # client server secret IP addresses username pptpd passwd

Edit/etc/sysctl. conf and set # net. ipv4.ip _ forward = 1 to net. ipv4.ip _ forward = 1. Run the command: sysctl-p

Add firewall rules:/sbin/Iptables-T nat-a postrouting-s 192.168.0.0/24-o eth0-j MASQUERADE

4. start pptp and restart firewall

Service pptp start

Servcie iptables restart

I finally got my own vpn server. this is really a tough task!
