using scp

install open-ssh first.

then if the host ip address is 1.1.1.130 and want to copy file called copy.txt to host's /home directory.

then scp copy.txt user@1.1.1.130:/home
the other way is scp user@1.1.1.130:/home/copy.txt or to give directory path

this can be used in iphone as well(never used android phone so i don't know)

isic & dependency file

isic is a very lousy network integrity check tool
as it says on the download link it can melt down one network very easy.
when I try last time it creates around 30,000+ packets per second.

http://packetfactory.openwall.net/projects/ISIC/index.html

installation is quite simple,
unzip with tar, configure, make and make install.
do not use this tool except to test your own network's integrity.
