What is Guptachar ?

Guptachar is a remote administration tool. This means that once you install Guptachar on computer A, you can control computer A from any computer B provided that both computer A and computer B are on the same IP based network like the Internet.

Guptachar also differs from most remote administration tools in one respect. It does not require its own client. This is because Guptachar runs as a web server. So once you've installed Guptachar on Computer A, all you need on Computer B is a web browser.

Guptachar has various features which allow you to administer the remote computer (aka Computer A) like browsing files, uploading files, executing programs, logging keys, shutting down and restarting, etc.

I've got Guptachar installed, how do I do the controlling ?

Say you've got Guptachar installed on Computer A whose IP address is 10.7.1.5, just point your web browser to http://10.7.1.5/ and enjoy.

If you've chosen to install Guptachar on a port other than 80 (discussed in the section on installation), say 8081, simply point your browser to http://10.7.1.5:8081/ instead.

How do I get to know the remote computer's IP Address ?

That's a good question. If computer A accesses the internet through dialup, it is likely to have a different IP address every time it logs on. This is why Guptachar has the facility of an IRCBOT.

Basically, if the IRCBOT feature is activated,whenever the remote computer (Computer A) goes online, Guptachar will connect to an IRC server with a predefined nickname, providing its IP address as its real name. So, whenever you want to know Computer A's IP address, you also connect to the same IRC server (use an IRC client like mIRC) and type /whois nickname.

While installing Guptachar (or by changing its server options), you can specify which IRC server and with what nick to logon. In case, the nickname you specify is already occupied, it'll try to logon with variations of the nick. Say, the nick you specified was gupt, it'll try to login as gupt, then gupt1, then gupt2, etc.

You can also ask Guptachar to connect to IRC via an HTTP proxy. Beware though, some IRC servers do not allow you to connect through a proxy (especially an open one).

How do I install Guptachar ?

Normal Installation

Just run the install.exe file. It'll ask you a series of questions and then install Guptachar on your machine.

Firstly, it'll ask you which port you want Guptachar to work on. Now webservers usually work on port 80. But it might not be such a good idea to operate on that port. Also, if you are installing it on an account with insufficient priveleges, you may be forced to use a higher port no. Remember this though, if you use a port other than 80, say 8081, you'll need to point your browser at http://ipaddress:8081/ instead of http://ipaddress/ or just ipaddress.

Then, it'll ask you whether you want access to the machine to be restricted and if so, it'll ask you for a username password pair.

Then it'll ask you whether you want Keylogging to be enabled. Following this, it'll ask you details about the IRCBOT feature.

Most of these options can be changed later through Guptachar, mostly using Server Options.

Making a Quick Installer

A quick installer is a stand alone .exe file, which has both the guptachar binaries as well as your inputted options stored within itself. Just running the .exe file will install Guptachar on the system without any user interaction.

To make a quick installer, just run makeqinst.exe. It'll first ask you for the filename of the quickinstaller (ie. the name of the .exe file) and then the same questions that it asks during normal installation.

Running makeqinst.exe does not install Guptachar on your system.

You'll need to run the generated .exe file to actually install Guptachar.
