DF Perl Informer v1.90b
DF™ Perl Informer — a free script that allows you to find out a lot of useful information about the server software, its configuration and physical parameters.
There is also information about the client, a built-in command line (web-shell) and a network password installer.
This script is an indispensable assistant when installing and configuring various scripts or testing hosting
- Server Information - Software & Hardware and load average. Information about the server’s operating system will help you choose the appropriate distribution, other data will help you configure the software correctly.
- User Information - allows you to find out your IP, user agent, which is useful for setting access by IP.
- Environment variables show the presence of GeoIP, help to learn about proxying (cloudflare) and choose a method for determining IP.
- Processes - shows the running processes, allows you to see which processes load the server or hang up.
- Command line (web-shell) - the ability to execute commands from the web, will help you unpack the archive, assign rights, remove the process, delete unnecessary files, etc.
- Set network password - the ability to assign a network password to the selected files or directory.
- Web server allowing to run cgi/pl scripts (Apache/Nginx/IIS).
- Perl 5 (installs on 100+ operating systems, including Linux / FreeBSD / Windows / MacOS)..

- Load Average for 1, 5, 15 minutes, the main indicator of server load.
- Awake processes (all processes, processes only the current user)
- Unix Inter-Process Communications (IPC: Shared Memory Segments, Semaphore Arrays, Message Queues).
- Users working at present on a server (Working users)
- Information about the processor: number, model name, frequency, the size cache memories, speed and other characteristics CPU.

- Are enumerated all variable environments in the alphabetical order: DOCUMENT_ROOT, GATEWAY_INTERFACE, GEOIP_ADDR, GEOIP_CONTINENT_CODE, GEOIP_COUNTRY_CODE, GEOIP_COUNTRY_NAME, HTTP_ACCEPT, HTTP_ACCEPT_ENCODING, HTTP_ACCEPT_LANGUAGE, HTTP_CDN_LOOP, HTTP_CF_CONNECTING_IP, HTTP_CF_IPCOUNTRY, HTTP_CF_RAY, HTTP_CF_REQUEST_ID, HTTP_CF_VISITOR, HTTP_CONNECTION, HTTP_COOKIE, HTTP_HOST, HTTP_REFERER, HTTP_UPGRADE_INSECURE_REQUESTS, HTTP_USER_AGENT, HTTP_X_FORWARDED_FOR, HTTP_X_FORWARDED_PROTO, PATH, QUERY_STRING, REMOTE_ADDR, REMOTE_PORT, REQUEST_METHOD, REQUEST_URI, SCRIPT_FILENAME, SCRIPT_NAME, SERVER_ADDR, SERVER_ADMIN, SERVER_NAME, SERVER_PORT, SERVER_PROTOCOL, SERVER_SIGNATURE, SERVER_SOFTWARE.
- Perl environments (Other Variables)
- Displays the running processes on the server for all users.
Unix displays information output by the command 'ps auxw' (USER, PID,%CPU,%MEM, VSZ, RSS, TT, STAT, STARTED, TIME, COMMAND).
Some servers may only display information about the current user's processes, depending on the server's security settings.
In Windows systems, the information displayed by the `tasklist` command is displayed (Image Name, PID, Session Name, Session number, Memory).
Command line (web-shell)
- Ability to execute commands on the server using the command line (analogue of shell).
- Commands are executed from the current user. Actions requiring root access will be denied.
- Lengthy commands may be interrupted due to the time limit of scripts running on the server (30 seconds).
- The feature is unsafe and is disabled by default! To enable it, you need to set a password on the script (the link "protect", upper-right corner) and create a special file on disk (piext.acs) to confirm that you have access to the site.
- There are hints for popular Unix commands. Working with files - copy (cp), rename/move (mv), delete (rm) files. Assignment of rights (chmod) and users (chown) on files. Creating (mkdir), deleting (rmdir) directories. File list output (ls), file search (find), archiving (tar, gzip). View disk space (df). Processes - showing (ps, top), removing (kill, killall). Process tracers and debuggers (ktrace, truss, strace, gdb). Working with IPC-display (ipcs) and delete (ipcrm).
Set network password (Htpassword Generator)
- Password protection of files or the entire directory in which the script is located. Enter the login, password and file name requiring authorization. The script will automatically create .htaccess and .htpasswd files and set a password.
- Unlike third-party network password generators, you do not need to find out and choose the password encryption algorithm.
- The function is also unsafe and is disabled by default, to enable it the same actions are required as to enable the web-shell.
