A sample RFC 1350 server, implemented from scratch according to the spec in Go.
The core logic is implemented in tftpserver.go, connection_service.go and memory_filestore.go.
Clone this repo and execute ./runServer.sh from a POSIX-compatible shell. Superuser permissions are needed due to it listening on the default port 69.
Using the default tftp client available from most package managers:
echo "Hello, world!" >> hello.txt
tftp 127.0.0.1
mode octet
put hello.txt
get hello.txt
Dependencies: Go 1 (developed with Go 1.11.2 (linux/amd64))
cd cmd/tftpd && go build
sudo ./tftpd
Read (RRQ), Write (WRQ) requests and unknown requests will be outputted to requestLog.txt in the current working directory.
for the server are located in lib/tftpserver_test.go and are integration-style tests.
These seem to like being run with go test within lib/, Visual Studio Code seems to be flaky running them on my machine.
