Hi,

I am trying to run leach protocol on ns2.35 using ubuntu 14.04 as platform.
I get an error when i try to execute the code leach_test in leach.err:

couldn't read file "/home/spc/ns-allinone-2.35/ns-2.35/mit/uAMPS/": illegal operation on a directory
while executing
"source.orig /home/spc/ns-allinone-2.35/ns-2.35/mit/uAMPS/"

invoked from within
"if [$instance_ is_http_url $fileName] {
set buffer [$instance_ read_url $fileName]

} else {

invoked from within
"source /home/spc/ns-allinone-2.35/ns-2.35/tcl/mobility/$opt(rp).tcl"

Why does this happen? and how can i fix this?
Thank you so much in advance

Best Regards,

Do these files exist?

Welcome to LQ.
Simple : You have a typo in one of the connected configuration files,
which you edited to /home/spc/ns-allinone-2.35/ns-2.35/*/*
