Remote File Access.
-
In our institution the firewall exclusively allows HTTP traffic alone. It does allow for ports other than 80 but the packet format should confirm to HTTP. Now I have a system at home connected to the internet by a router. I even have a static IP provided to me by my ISP. But in order to remotely access files not only for reading / opening alone but even for modification, upload, download etc. i need to use FTP. But the packets are dropped by the firewall. How and in which language can we write an ActiveX component which can convert these packets to HTTP from my institution system for outgoing traffic and also reconvert the HTTP to the original format at my home system end. Similarly as any inbound traffic other than HTTP is dropped so the same has to be performed at my home end also. Also tell me how what protocol and ports does mstsc.exe (WindowsXP) uses. Could you please throw some light on the above problem. In summary my main objective is to have a directory listing of my system(home) files so that I can use them locally. How to do it?

I think my question was ambiguous. I actually want to develop my own ActiveX component to do the protocol conversion say from FTP to HTTP while outbound from my firewall and vice versa at my Home system end. At the same time I also want to do the above thing while coming traffic comes from my home system to my institution system so as the firewall doesn't discard the packet again. Hope i'm clear now. I want some programming / implementation concept.

OK, say you do this. If the company is that strict on controlling traffic through that firewall, how are you going to get them to install a component on the web servers that translates your traffic back to unencapsulated FTP?? You need components on BOTH sides of the firewall to get this to work. You need a server (possibly web service) running on the inside of the firewall and you need a client application running on your home machine.

2006, 2007Exactly. U seem to read my mind. I have thought of the same kind but implementation wise I'm confused. IIS 6.0 is running on both ends. because the mechanism will always be like - institute system triggered, as the firewall will not allow inbound request, hence I need a component which will do encapsulation an decapsulation at both ends. Now please suggest a way to do this. I can even log into my system from any Cyber Cafe using mstsc. But I can't from my instiute system. Please help

But will it give me permissions like i have in explorer? Can I download and upload any file in form of directory services? I'm not aware of it hence I'm asking so
