Hi,

I am using the kickwebs approach to have lighttpd use port 80. this pushes the default web interface of my DNS-323 (Actually a CH3SNAS) to port 81.

I want to know more on how this works. THe killwebs.sh just kills the defaults webservice. I suppose the default webservice is restarted then and will switch to port 81 because port 80 is already in use by lighttpd by then.

Where is the port for the default webservice configured? Where is it configured that it switches to port 81 if port 80 fails?

The problem I have with the kickwebs method is that if for some reason the lighttpd fails to start after a reboot, than the default webservice will again be available at port 80 and thus to the whole internet.

Maybe there's some simple other service I could start at port 80 after lighttpd. If lighttpd start fails, then this simple service will occupy port 80 and prevent the default interface to become available?

Any ideas?

Thanks. Since it's hardcoded

Code:

static int                      port = 80;                                              /* Server port */
static int                      retries = 5;                                    /* Server port retries */

/* 
*      Open the web server on the given port. If that port is taken, try
*      the next sequential port for up to "retries" attempts.
*/
        websOpenServer(port, retries);

(Is it the same on ch3snas?)

Your nice little c program will be needed.Should I put a wait/sleep in there or is the accept a blocking call?
