PositiveSSL + Nginx Configuration

By on October 1, 2011 in Experience

Positivessl.com will offer you four files when you finish the application procedure:

 

Your domain's key file: domain.key or domain.pem

Your domian's certificate: domain.crt

Intermediate certificates: PositiveSSLCA.crt ,  UTNAddTrustServerCA.crt

Root certificate: AddTrustExternalCARoot.crt

 

1) Make a certificate chain:

If your Key file is domain.key, you'd better rename it to domain.pem

 

mv domain.key domain.pem

 

Then we have to concatenate all the certificates to one file in a special top to root chain: domian's certificate + Intermediate certificates + Root certificate

 

cat domain.crt PositiveSSLCA.crt  UTNAddTrustServerCA.crt AddTrustExternalCARoot.crt > domain_chain.crt

 

 

2) Modify Nginx conf file, here is a example:

server
{
listen 443;
server_name domain.com;

ssl on;
ssl_certificate /root/domain_chain.crt;
ssl_certificate_key /root/domiann.pem;
ssl_protocols SSLv3 TLSv1;
ssl_ciphers ALL:-ADH:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP;

location / {
…
…
}

…

}

Limit the Number of Connecting Threads from A Single IP to Protect CC Attacking

By on September 24, 2011 in Experience

This method may help you alleviate the CC attacking from a single IP.

 

1) Install iptables:

 

Ubuntu/Debian:

apt-get install iptables

CentOS: 

yum install iptables

 

2) Set the maximum number of threads that a single ip can connect you server at the same time:

iptables -I INPUT -p tcp –dport 80 -m connlimit –connlimit-above 10 -j DROP

iptables-save > /etc/noddos

Here 10 is the maximum number, you can change it to others, then:

vim /etc/rc.local

Add:

iptables-restore /etc/noddos

 

ALL DONE.

 

 

Setup Nginx HTTPS (SSL) Inverse Proxy

By on September 19, 2011 in Experience

We aim to setup an inverse proxy “https://google.vpscouponcode.com” to “https://encrypted.google.com”.

 

1) Download Nginx and install it. (Make sure to include the SSL Module)

 

2) Goto your DNS panel and make a new A record (Proxy URL, here we take “google.vpscouponcode.com” as an example) to your inverse proxy server ip.

 

3) Forge a Self-authorized Certificate

 

Make a dictionary for the Certification files:

 

cd ~

mkdir ssl

cd ssl

Generate a CA Private Key:

openssl genrsa -out ca.key 4096

Generate a  CA Certification:

openssl req -new -x509 -days 3650 -key ca.key -out ca.crt

Generate the Private Key of your server:

openssl genrsa -out server.key 4096

Generate the Certificate Signing Request of your server (Important: Common Name is your inverse proxy URL ):

openssl req -new -key server.key -out server.csr

Using the CA Certification to sigh your Certificate Signing Request:

openssl x509 -req -days 3650 -in server.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out server.crt
