IP tunnel problem


I'm trying to create a tunnel to my linux box. After reading several howto-s I'm using the following command:

ip tunnel add tunl0 mode ipip local remote aaa.bbb.ccc.ddd

All I get is:

ioctl: No buffer space available.


BTW: if I try to create GRE tunnel I get the same error. Both IP and GRE tunneling is compiled into my Kernel 2.4.22-ow1

Once again I'm answering my question myself Perhaps it will helo those who have similar problem:
the device tunl0 already exists in the system, it appeared there automatically after enabling IP/IP tunneling in kernel. I have to use another name like tunl1 or something.

Thanks for the answer. 9 years have gone by and now it has saved me probably quite a bit more searching.
