how to create ip tunnel ????
I have downloaded a mobile ip program called dynamic mobile ip ( version 0.8.1 ) from:
I had run the HA, FA and MN on 2 laptops and one desktop. It is successfully communicate each others. But, I had found out that there is no throughput in the adhoc network although it can communicate each others.
I have some questions to ask because i really running out of idea to solve the problems. Hope you can help me. The problems are below:
1) From the README file of dynamic mobile ip, there is a small part under "RUNNING" in README file, which are:
"In order to be able to use the IPIP tunneling you must make sure that the
IPIP tunneling module (ipip.o) is loaded. This can be done with 'insmod ipip'
if the module is compiled to the Linux kernel as a loadable module."
I had search through those files inside downloaded dynamic mobile ip folder, but i cannot search the ipip.o file in it. May I know is it i have to download it from somewhere or is it as you mentioned to create the file which is for ipip.o ??
2) I had went to the dynamic Mobile IP forum and found a link as below:
The message contain are :
dynamics version 0.8.1 should work as it is. Your kernel should be
enabled with CONFIG_IP_ADVANCED_ROUTER and CONFIG_IP_MULTIPLE_TABLES
options. other wise FA doesn't work.
May I know where can i enable CONFIG_IP_ADVANCED_ROUTER and CONFIG_IP_MULTIPLE_TABLES ??
I did found a link about ipip tunneling which also mentioned about CONFIG_IP_ADVANCED_ROUTER and CONFIG_IP_MULTIPLE_TABLES , but i really don't know where it located. The link as below:
3) May I know to load ip tunneling module, is it "modprobe ipip" and "insmod ipip" both are same function command to create tunnel ?
Because when i type modprobe ipip, it is ok in terminal. But when i type insmod ipip, there is an error message said that:
"insmod: can't be read ipip , no such file or directory".
Please help me if you know about it. Your helps are much needed and appreciated.
