Modify existing module on Slax

for example
if you use some module then face a path problem, you can modify it.
the below message is showed when I run tsocks module what I have installed

ERROR: ld.so: object '/usr/lib/libtsocks.so' from LD_PRELOAD cannot be preloaded: ignored.


1. download tsocks module from http://bencoh89.free.fr/slax6modules/

2. extract content of tsocks module to a directory

mkdir tsocks
lzm2dir tsocks.lzm tsocks/

3. pack the module back to the .lzm format by using

dir2lzm tsocks/ tsocks.lzm

vi /etc/danted.conf

# the package seems not complied with libwrap support.
#user.libwrap: nobody
