[ns] routing outside the subnet.

[sxroy1]

under the dsdv.cc file there is a function which drops the packet if its 
destined for outside the given subnet, the function is as follows:
DSDV_Agent::diff_subnet(int dst) 
{
char* dstnet = Address::instance().get_subnetaddr(dst);
if (subnet_ != NULL) {
if (dstnet != NULL) {
if (strcmp(dstnet, subnet_) != 0) {
delete [] dstnet;
return 1;
}
delete [] dstnet;
}
}
//assert(dstnet == NULL);
return 0;
}
 can any one give me any idea abt how to avoid this and add the route in the 
table so that routing to other subnets could be possible ?

any help would be really appriciated. thanks
roy

[ns] making ns2 to write to an output file

[nalinaksh gaur]

Hi everybody,

I am trying to make ns2 to write some statistics to an output file.  I
am writing the following code in some c++ file inside the ns2
directory :

#include fstream
using namespace std;

ofstream a_file (example.txt);
a_fileThis text will now be inside of example.txt;
a_file.close();
...

Now when I 'make' ns2, I get the following error message:

 error: expected constructor, destructor, or type conversion before '' token
error: expected `,' or `;' before '' token
error: expected constructor, destructor, or type conversion before '.' token
error: expected `,' or `;' before '.' token

How can I fix this problem?

Thanks!
