Help Needed! Some Netwroking Problem

[abhay 0]

may be there is a way to attach the no-ip service and the web-server(ie port 80) through MTNL connection

is all incomming/outgoing of no-ip and the webserver through MTNL and rest through sify & and yup i think that is possible, isint it

[StaticElectricity 8]

ooh boy, i really didnt get what you ppl are trying to do, but as far as i can say,

set up a dummy page at the MTNL IP,use some scripting such that the dummy page finds out the SIFY Public ip, and redirects all the hits to your SIFY ip.

I guess thats all you can do.

whatever u said could work dint try it thought seems to be some kinda technical glich there but even if it works it wont solve the problem

of actully having two diffrent connection one with public ip and second with pvt ip and most of the traffic should go from the pvt one

Possible......yes, how, that's what we are trying to figure out. Lets see what linuxguy thinks of my last idea, cuz I don't really know much about the internal working of TCP/IP.

[abhay 0]

linux is true ! hey whats ur real name by d way

if i connect to one ip address then i have to communicate with that ip only what we actully need is all mtnl connection should be on MTNL and all sift connection through sify

1) both should not mess with each other

2) a way to keep specific appz to comunicate with perticular NIC (as in no-ip and all kinda webservers <-- all outgoing and incomming connections through from these appz through one (MTNL NIC))

abhay, you can run the webserver on the MTNL IP and surf the internet on the Sify IP. That can be done without a problem. But then data exchange on the MTNL IP will be counted and since you have a limit, you might exhaust your limit pretty quickly if your webserver hosts big files

Guys, the problem with running a webserver on the Sify IP is that abhay is NATed behind the router's IP. For example:

Sify's router -> External NIC = 212.x.x.x Internal NIC: 10.0.0.1

Now, all customers connect to Sify's internal NIC which means they all have IPs in the range 10.0.0.2-10.0.0.254. Sify's router handles authentication, DHCP and NATing. Since it doesnt port forward all the ports, what happens is that the request sent to the Sify's external IP wont be forwarded to abhay's internal IP. Hence, even if abhay knows the external IP of Sify's servers, it wont be of any use lest sify configures a DMZ or Port forwarding.

Sify can setup a DMZ for Abhay or they can forward selective ports to his computer but I dont think they will be willing to do that

Life is complicated

aree linuxbhaiya woh to sabko pata hai ki yeh mera problem lets stop describing the prob and get to work and get a solution for it

if it is solved it can help anybody who wants a cheap PUBLIC IP SOLUTION

i mean who gives a public ip for just RS 80 / month MTNL ka dabba kuch toh kaam ayega

PS rs 80 is mim chages then rest the charges are as per usage

abhay, the per MB charge is what s**ks. Otherwise i would've gone for MTNL myself. Why do you think I keep ranting about ****ty broadband in India?

I don't see how you can do that either? You would still have to change the routing tables right? And if you change them, they work on both connections right?

my webserver would be running on MTNl so max datatransfer would be 30 - 40 mb a month so my bill would reach max 150 RS

that good enough for a256 connection

i think we can modify routing table in such a way that some appz work with one NIC and some with other

i dont know how it is done though . theorytically it is possible

Ok sorry for off topic posting........but I am really remindef of this quote "Theory is when you know something, but it doesn't work. Practice is when something works, but you don't know why. Engineers combine theory and practice, nothing works and they don't know why!!"

[linuxguy 0]

adwait, you still havent gotten it. There isn't any need to modify the routing tables. The Apache server can bind itself to the MTNL IP. While we can set the default gateway to Sify, so all other apps will communicate through Sify while Apache does through MTNL.

aaah! aisa hai kya.........never knew that. Hmm......something to tinker with in the holidays (only 2 papers left......yay!!)

[abhay 0]

bhaiyoon aapas mein hi discuss karna hai ya iss windows wale ke problem bhi suljhana hai

[linuxguy 0]

Abhay, dont ask me to guide you in Windows. I absolutely dont use windows :|

[cracker 0]

I have a simple solution for u.

install Microsoft’s virtual pc and run 2 pc in 1

download virtual pc from Microsoft’s web site.

If u don’t like ms stuff than u can go forVMware Workstation 5

It is virtual workstation.

Get its trial version from

http://groups.google.co.in/group/desi-tek/...a957181995506f6

it is easy to configure and use

where exatly are you trying to get @

how will it solve my problems ??

[ashoksoft 83]

Think of this funda...

U host a web page... and provide the IP to the world. (consider it is 203.*.*.* - MTNL)

And now u wish that when a user requests a page from ur MTNL address, u send him a page (maybe via re-direction) from ur SIFY connection.

Aren't we missing something major here??? If u could do the transmission thro ur sify IP, why do u need two connections? (and logically, isn't it simpler to do a simple server-send, rather than a server-redirect?)

Cheers

Ashok

[cracker 0]

by using virtual pc u can have two or more os @ 1 time

on 1 pc

u can use sify in 1 and mtnl in other to run a webserver

ok did it

got VMware and virual pc cracked

so now some R&D left to do on it

hmm thx for d idea buddy! will surely try on it

hey btw isint there any lesser memory consuming way out ! ???

[ashoksoft 83]

try the yonger bro of them all .."bochs system emulation"

cheers

Ashok

PS : it is free too (opensource)!!

[linuxguy 0]

eh? i dont understand how exactly will VPC solve his problem. Forget solving problems, it is going to complicate them further. And I have told this plenty of times, what Abhay is trying to achieve is _not_ possible with TCP/IP

Will Amd Athlon xp 64bit 2800+(1.81Ghz) with 512mb ram do?

hmm no wonder VMware hangs up my XP
