This will not help in whatever you are trying to do. The error you are seeing is not from insmod, it's from the run-time linker. If you had run 'ls' instead of insmod, you would have seen the same error. > > I am trying to port the cisco vpn client to then > > kernel 2.5.x.

You can't access is directly from a kernel module. Does your module really belong in the kernel? Or is it better to have it as a user-mode app? -Ravi. __________________________________ Do you Yahoo!? SBC Yahoo!
