Netstat : How to Find and Check Number of Connections to a Server

netstat -na
Display all active Internet connections to the servers and only established connections are included.

netstat -an grep :80 sort

Show only active Internet connections to the server at port 80 and sort the results. Useful in detecting single flood by allowing users to recognize many connections coming from one IP.

netstat -n -p|grep SYN_REC | wc -l
Let users know how many active SYNC_REC are occurring and happening on the server. The number should be pretty low, preferably less than 5. On DoS attack incident or mail bombed, the number can jump to twins. However, the value always depends on system, so a high value may be average in another server.

netstat -n -p | grep SYN_REC | sort -u
List out the all IP addresses involved instead of just count.

netstat -n -p | grep SYN_REC | awk '{print $5}' | awk -F: '{print $1}'
List all the unique IP addresses of the node that are sending SYN_REC connection status.

netstat -ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n
Use netstat command to calculate and count the number of connections each IP address makes to the server.

netstat -anp |grep 'tcp\|udp' | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n
List count of number of connections the IPs are connected to the server using TCP or UDP protocol.

netstat -ntu | grep ESTAB | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -nr
Check on ESTABLISHED connections instead of all connections, and displays the connections count for each IP.

netstat -plan|grep :80|awk {'print $5'}|cut -d: -f 1|sort|uniq -c|sort -nk 1
Show and list IP address and its connection count that connect to port 80 on the server. Port 80 is used mainly by HTTP web page request.

netstat -nt | grep 80 | wc
find total connection

!includedir /etc/mysql/conf.d/I’ve gone back and forth over the years configuring MySQL for optimal performance, and while I know I’m not there, I now have a new baseline to build from. From a post called Standard MYSQL my.cnf configuration, you can see all the base information, but also things like:

key_buffer=256M # 64M for 1GB, 128M for 2GB, 256 for 4GBWhich defines the value (256M) but then spells out ideal base values for you to start with if you have more RAM on your system. This is very helpful, I’m tried to go a step further by combining it with Debian’s default my.cnf that comes on 5.0 (lenny) for MySQL 5. As I’m always open for suggestions for improvements, please comment if you have a different view on these choices, thanks. Here it is:

Howto Secure Apache

1. Use the latest and most current version. Right now the latest is the Apache 2.2 series
2. Make sure you’ve installed all the latest security patches
3. Hide the Apache Version number, and other sensitive information
4. Make sure apache is running under its own user account and group
5. Ensure that files outside the web root are not served
6. Turn off directory browsing (mod_autoindex)
7. Turn off server side includes (SSI)
8. Turn off CGI execution
9. Don’t allow apache to use symbolic links
10. Turning off multiple Options
11. Turn off support for .htaccess files
12. Use the Apache mod_security
13. Disable all unnecessary modules
14. Make sure only root has read access to apache’s config and binaries
15. Lower the Timeout value
16. Limiting large requests
17. Limiting Concurrency
18. Restricting Access by IP
19. Adjusting KeepAlive settings
20. Run Apache in a Chroot environment

SSL: Verifying that a Certificate matches a Private Key

The private key contains a series of numbers. Two of those numbers form the “public key”, the others are part of your “private key”. The “public key” bits are also embedded in your Certificate (we get them from your CSR). To check that the public key in your cert matches the public portion of your private key, you need to view the cert and the key and compare the numbers.
Normally it requires some manual number matching to match a given private key with a given certificate, however with this command you are able to do a comparison automatic:

$ (openssl x509 -noout -modulus -in server.pem openssl md5 ;
openssl rsa -noout -modulus -in server.key openssl md5) uniq

(If more than one hash is displayed, they don’t match)

CSR : Certificate Signing Request

How to Generate CSR use OpenSSL

1. Create a RSA private key for your Apache server, PEM-formatted:

#openssl genrsa -out domain.com.key 1024

2. Create a Certificate Signing Request using the RSA private key created above (output will be PEM format):

#openssl req -new -key domain.com.key -out domain.com.csr

Note that the Common Name field is the field where the domain name should be stated.

How to setup CSR

1. Copy your issued certificate, intermediate certificate and key file (generated when you created the Certificate Signing Request (CSR)) into the directory that you will be using to hold your certificates.
2. Open the Apache ssl.conf file and add the following directives: *

SSLCertificateFile /path to certificate file/your issued certificate *
SSLCertificateKeyFile /path to key file/your key file *
SSLCertificateChainFile /path to intermediate certificate/gd_intermediate_bundle.crt

Save your ssl.conf file and restart Apache.

CSR : Generate a Certificate Signing Request (CSR) for Apache + Mod SSL + OpenSSL

1. Install OpenSSL

2. Create a RSA key for your Apache server:
cd /apacheserverroot/conf/ssl.key (ssl.key is the default key directory.)

NOTE: If you have a different path, cd to your server’s private key directory...

3. Type the following command to generate a private key that is file encrypted. You will be prompted for the password to access the file and also when starting your web server.

Warning: If you lose or forget the pass phrase, you must purchase another certificate.

#openssl genrsa -des3 -out domainname.key 2048
You could also create a private key without file encryption if you do not want to enter the pass phrase when starting your web server:

#openssl genrsa -out domainname.key 2048
Note: We recommend that you name the private key using the domain name that you are purchasing the certificate for ie domainname.key

4. Type the following command to create a CSR with the RSA private key (output will be PEM format):


#openssl req -new -key domainname.key -out domainname.csr


* Note: You will be prompted for your PEM pass phrase if you included the "-des3" switch in step 3.

5. When creating a CSR you must follow these conventions. Enter the information to be displayed in the certificate. The following characters can not be accepted: < > ~ ! @ # $ % ^ * / \ ( ) ?.,&

Common Name : The fully qualified domain name for your web server. This must be an exact match.

Organization : The exact legal name of your organization. Do not abbreviate your organization name.

Organization Unit : Section of the organization

City or Locality : The city where your organization is legally located.

State or Province : The state or province where your organization is legally located. Can not be abbreviated.

Country : The two-letter ISO abbreviation for your country.

6. Do not enter extra attributes at the prompt. Warning: Leave the challenge password blank (press enter) Note: If you would like to verify the contents of the CSR, use the following command:


#openssl req -noout -text -in domainname.csr

7. Submit the CSR during a enrollment by opening the CSR in a text editor such as Notepad or Vi and copying and pasting the text into the Enter CSR box.

8. We recommend that you create a backup of your private key

To do this make a copy of the private key file (domainname.key) generated in step 3 and store it in a safe place. If you lose this file, you must purchase a new certificate.
* The private key file should begin with (when using a text editor)

-----BEGIN RSA PRIVATE KEY

----- and end with -

----END RSA PRIVATE KEY-----.


To view the contents of the private key, use the following command:
openssl rsa -noout -text -in domainname.key

Linux (Debian) : user nologin shell

เนื่องจาก vsftpd ใช้ user ตรงๆ จาก os เลย ดังนั้นการสร้าง user ก็เป็นการสร้าง user ของ os ด้วยคำสั่ง useradd ซื้อมีออฟชั่นให้ใช้ล้านเจ็ดสิบเอ็ดแสน

useradd [options] LOGINNAME

เมื่อสร้าง user แล้ว อย่าลืมตั้งรหัสผ่านให้ user ที่สร้างด้วยคำสั่ง passwd LOGIN ด้วยนะครับ

ใน option เราต้องระบุ shell สำหรับ user นั้นด้วย แนะนำให้ระบุ shell ไปที่ /usr/sbin/nologin เพื่อที่จะให้ user ท่านนี้สามารถ เข้าใช้ ftp ได้ แต่ไม่สามารถใช้งาน shell ได้
แต่จะใช้ /usr/sbin/nologin ได้นั้น ต้องไปแก้ไขไฟล์ /etc/shells ก่อน ให้ดูว่า มีบรรทัด/usr/sbin/nologin อยู่รึยัง ถ้ายังไม่มี ให้เพิ่มเข้าไป

dist-upgrade vs upgrade

This command installs the latest versions of any out-of-date packages on your system. It never installs a package that is not yet installed.

apt-get dist-upgradeThis command installs up-to-date version of packages, and may install additional packages.

if you want to do a distro-upgrade, use dist-upgrade. For instance, moving from Debian -stable to Debian -testing. Dist-upgrade is a special upgrade that is used if you are fetching packages from a new location, which is specified in /etc/apt/sources.list

If you want to simply upgrade the packages you have installed for your current distro, use 'apt-get upgrade'.
