CGI change server IP address ??

[skyy]

Hi..

I am working on a CGI script to enable client to obtain the server ip address and then change to the IP address it prefer.

The server IP address can be obtain from the environment variable SERVER_ADDR

I am trying to change the IP address of the server with the following script:

#!/usr/bin/perl -w

use strict;

my $URL="http://192.168.28.130" ;
print "Status: 302 Moved\nLocation : $URL\n\n";

system("/sbin/ifconfig eth0 192.168.28.130" );


I managed to change the IP address of the server. But the Re-driection of the web page doesnt not happen.

Any idea how to solve this???

You need to print a meta refresh tag to redirect the browser. Search on google for "meta tag tutorial" or something similar.

Hi... that doesnt work. I tried already. Thanks...

print qq(<meta http-equiv="refresh" content="0; URL=http://192.168.28.135" >);

Did you print an http header first?

Yes...

print "Content-type: text/html\n\n";

hmm, I'm stumped. I don't know why it does not work.

I am also figuring out what happpen...

when i remove the change IP command:

system("/sbin/ifconfig eth0 192.168.28.130" );

the script works well with the redirection. But then i won't be able to change the server IP address....

Maybe Miller or Paul will have some advice for you. I don't know what the problem might be.

You could give it a try with the below.

#Redirect The Page
@redirect='<meta http-equiv="refresh" content="0;URL=http://192.168.1.149/feedback/thankyou.html">';
print @redirect;

Yes...

print "Content-type: text/html\n\n";

192.168.*.* is a private IP subnet. You are not going to be able to redirect an external user to an IP in that range. Their browser will instead look in their own private subnet.

Also, changing the IP address on a system level has no effect on the web. Using ifconfig will just brake things. Don't do that.

Finally, if you set it to a real IP address, the meta redirect should work. You can also use a redirect header if you're using mod_perl. Or if you want to rely on the JavaScript level, you can use a window.location assignment.

Hi Miller,

so is there any other way to change IP address?
Is there no way to do a auto redirect of web page?

Thanks..
