Simple network TCP or UDP client and server utility. Used for validation that the host and port is open. (i.e., not blocked by firewalls) Note: This is a repo to test out various things. If you really want a utility to test tcp and udp connections, check out *netcat*. Start tcp server: nc -l 1234 Start tcp client: nc 127.0.01 1234 Start udp server: nc -l 1235 -u Start udp client: nc 127.0.01 1235 -u Start TCP server: snet -port 3000 Start TCP client: snet -client -host:1.2.3.4 -port 3000 When done, type in "STOP" in the client and "control-c" on the server. Start UDP server: snet -port 3001 -udp Start UDP client: snet -client -host:1.2.3.4 -port 3001 -udp On windows, might need to open an elevated prompt: netsh advfirewall firewall add rule name="TCP Port 3000" dir=in action=allow protocol=TCP localport=3000 netsh advfirewall firewall add rule name="UDP Port 3001" dir=in action=allow protocol=UDP localport=3001 On linux, if using UFW: sudo ufw allow 3000 sudo ufw allow 3001/udp sudo ufw allow from 1.2.3.4 to any port 3000 inspired by: https://www.linode.com/docs/guides/developing-udp-and-tcp-clients-and-servers-in-go/ # Development notes: # trying tcp server # start server go run main.go -port=1234 # start client go run main.go -client -host=127.0.0.1 -port=1234 send "Hello!" send "STOP" # initial go mod init github.com/mkinney/snet go mod tidy Note: Generated a personal access token with perms to do releases. workflow for a release: - commit changes - tag release git tag -a v0.2 -m "v0.2" git push origin --tags - create a release in GitHub for that tag git push See these other repos: https://github.com/mkinney/snet_win To build nupkg file that can be used for a Windows Chocolatey install https://github.com/mkinney/snet_rpm To build rpm package for Red Hat based linux systems https://github.com/mkinney/snet_packer To build an Ubuntu based docker image with snet installed https://github.com/mkinney/snet_apt To build apt package for Ubuntu
