Hi again!!!

I m able to compile the original code by VJ.. Actually I included my
own file.namely
reference:: http://web.cecs.pdx.edu/~jrb/tcpip/misc.src/traceroute.c

#include "ip_var.h"
#include "udp.h"
#include "udp_var.h"

But then the problem is....

I m not getting any kind of error but ... when I run the code, the
output is what I did not expected. ie

whenever I do a "traceroute" to any system in my LAN, it shows time
out..

1 * * *
2 * * *
3 * * *

......
and so on...

Can anyone suggest me in this regard why the program is not giving the
proper output.

regards,
tiken

Are you running the program as root, or setuid root?

traceroute needs access to root privledges in order to function.

yes, I m running the program as root.
The problem I m facing is that
the function wait_for_reply(sock,from) returns 0 everytime
ie a time out indication.. I even tried to increase the waittime but
could not help.

I think thers some trouble in the "select()" call because I m getting
the Socket descriptors value...

Can anyone put some pointers in this regard.
