  • proxychains

    proxychains allow you to route traffic using proxy servers. This is useful for routing traffic throihg applications that do not support proxy by default. For example, i use ssh through proxy chains.

    To install proxychains on Ubuntu, run

    apt install -y proxychains
    

    Now you need to edit /etc/proxychains.conf and add your proxy servers.

    sudo vi /etc/proxychains.conf 
    

    On my computer, i use SSH tunnel to a sevrer on port 7878, so i added following to end of my proxychains.conf

    socks5  127.0.0.1  7878
    

    To text proxy proxychains, run

    boby@sok-01:~$ curl checkip.amazonaws.com
    59.92.71.53
    boby@sok-01:~$ proxychains curl checkip.amazonaws.com
    ProxyChains-3.1 (http://proxychains.sf.net)
    |DNS-request| checkip.amazonaws.com 
    |S-chain|-<>-127.0.0.1:7878-<><>-4.2.2.2:53-<><>-OK
    |DNS-response| checkip.amazonaws.com is 34.193.115.2
    |S-chain|-<>-127.0.0.1:7878-<><>-34.193.115.2:80-<><>-OK
    51.38.246.115
    boby@sok-01:~$ 
    

    As you can see when using proxychains, you get a difernt IP as traffic get routed through proxy server specified in proxychains.conf

    Proxychains show some connection info, you can hide this by editing proxychains.conf and uncommenting the line

    # Quiet mode (no output from library)
    #quiet_mode
    

    With quite mode enabled, you will see

    boby@sok-01:~$ proxychains curl checkip.amazonaws.com
    ProxyChains-3.1 (http://proxychains.sf.net)
    51.38.246.115
    boby@sok-01:~$

  • Server Load

    Here are some useful commands to check server load.

    iostat shows disk IO usage. %iowait shows how much time the process waits for disk operation. This should be 0. If you are on VPS, check for %steal to see if the host server is overloaded.

    iostat 1 10
    

    Checks for processes in ā€˜Dā€™ state

    for x in `seq 1 1 30`; do ps -eo state,pid,cmd | grep "^D"; echo "-"; sleep 2; done
    

    Top processes using CPU resources

    top -bn 1 | head -20
    

    Check Running Process

    ps aux
    top
    atop
    pstree
    

    Check For Bad Scripts

    WPRobot plugin for wordpress take lot of cpu usage, find sites using WPRobot

    find /home -name 'wprobot.php'
    
  • Requesting a zone trasnfer with dig

    To request a zone transfer using dig, use

    dig @NAME_SERVER_HERE  -t AXFR  DOMAIN_NAME_HERE
    

    Example

    [root@vps3 poweradmin]# dig @server10.hosthat.com  -t AXFR  bizhat.com
    
    ; <<>> DiG 9.5.1-P2-RedHat-9.5.1-2.P2.fc10 <<>> @server10.hosthat.com -t AXFR bizhat.com
    ; (1 server found)

  • Steam store games on different Disk

    I have a 250 GB SSD as boot drive. My steam games installed on a 2nd 2 TB hard disk. After reinstalling Ubuntu, i installed steam with.

    apt install steam
    

    Steam does not show the games installed on the 2 TB HDD.

    To get the games work, i renamed steamapps folder, them created a symlink to directory on the 2 TB HDD where games are installed.

    Stop steam, then do the following. /mnt/data/SteamLibrary/steamapps is the directory where my games are installed. Change it to whatever directory where your games are installed.

    cd ~/.steam/debian-installation/
    mv steamapps steamapps-old
    ln -s /mnt/data/SteamLibrary/steamapps
    

    Now start Steam, you will see the games.
