Teleporter is a small utility in the vein of netcat to send files quickly from point A to point B. It is more convenient than netcat in that you don't have to run a separate command with file redirection for each file you wish to transfer.
Teleporter lets you pass the destination and a list of files you wish to send and it will create those files with the proper filenames on the receiving end. Each Teleporter binary can act as a client or a server so there's no need to move multiple software packages around.
Teleporter can recursively copy, overwrite, rename, and keep a backup of the destination file.
Teleporter now does delta file transfers using the xxHash3 hashing algorithm for files being overwritten, hashing the entire file as well as splitting the file into a number of smaller chunks.
The protocol Teleporter implements to transfer files is called Teleport and is defined in
To start a teleporter in server (receiving) mode, just run:
Teleporter will default to listening on
0.0.0.0:9001 for incoming connections.
Here are some additional options for receiving files:
Usage: teleporter listen [OPTIONS] Options: --allow-dangerous-filepath Allow absolute and relative file paths for transfers (server only) [WARNING: potentially dangerous option, use at your own risk!] -m, --must-encrypt Require encryption for incoming connections to the server -p, --port <PORT> Port to listen on [default: 9001] -h, --help Print help
To start a teleporter in client (sending) mode, run:
teleporter send [-d <destination>] -i <file> [[file2] [file3] ...]
Here are some additional arguments for sending files:
Usage: teleporter send [OPTIONS] Options: -i, --input [<INPUT>...] List of filepaths to files that will be teleported -d, --dest <DEST> Destination teleporter host [default: localhost] -p, --port <PORT> Destination teleporter port [default: 9001] -o, --overwrite Overwrite remote file -r, --recursive Recurse into directories on send -e, --encrypt Encrypt the file transfer using ECDH key-exchange and random keys -n, --no-delta Disable delta transfer (overwrite will transfer entire file) -k, --keep-path Keep path info (recreate directory path on remote server) -b, --backup Backup the destination file to a ".bak" extension if it exists and is being overwritten (consecutive runs will replace the *.bak file) -f, --filename-append If the destination file exists, append a ".1"(or next available number) to the filename instead of overwriting -h, --help Print help
Teleporter will transfer files with their name information as well as their file permissions. Any file path information will be lost unless the
-k option is enabled. All the received files will be written out in the CWD where the server side was started unless the server was started with the
--allow-dangerous-filepath option. When overwriting a file with the
-o option, additional modifiers can be used, such as
-b to make a backup of the original file, or
-n to disable delta file transfers and always overwrite the entire file.
Scan for Teleporter Instances
To have teleporter scan the local network for any reachable teleporter instances, run:
This will iterate through all the network devices (except the loopback device!) and will attempt to locate any teleporter servers listening on a specific port. It will report back if any server is found and what version they are running. This feature is only available on teleporter v0.10.7 and higher.
Here are the additional arguments for scanning:
Scan all network devices for any reachable Teleport listeners Usage: teleporter scan [OPTIONS] Options: -p, --port <PORT> Port to scan for [default: 9001] -h, --help Print help
Rename / Copy-To
Teleporter can now set remote file locations, or file renaming, via the
: operator. Similar to how
Docker allows quick mounting of directory locations, Teleporter will first attempt to open a file by the full given path, if that file does not exist, it will see if there are any colons (
:) in the filename. If present, it will split the filepath and attempt to open on the first portion of the name. If that succeeds, Teleporter assumes this is a file rename / copy-to. Teleporter will also need the
-k option, to keep filepath information. Otherwise only the file name will be changed.
For example, given the following command:
./teleporter -i ~/Downloads/ubuntu-20.04.3-live-server-arm64.iso:/tmp/ubuntu.iso -k
(and assuming the server was started with
--allow-dangerous-filepath), Teleporter will first attempt to open
~/Downloads/ubuntu-20.04.3-live-server-arm64.iso:/tmp/ubuntu.iso, if that fails, it will attempt to split the path on
: and open
~/Downloads/ubuntu-20.04.3-live-server-arm64.iso. If that succeeds, then it knows it is a rename / copy-to operation and will set the destination filepath to be the second part of the string:
/tmp/ubuntu.iso. On the server, it will only receive the file for
/tmp/ubuntu.iso. If the
-k argument was omitted, the server would just receive the original file renamed as
If you have Rust and Cargo installed, Teleporter can be quickly compiled and installed by running the following command:
cargo install --locked teleporter
This will install Teleporter to
~/.cargo/bin/teleporter, which might need to be added to your shell's
