# AnySync Netcheck Tool

A simple tool that checks the ability to connect to Anytype nodes. It was created to test network and TLS (sync) issues.

The *Netcheck* Tool opens a connection to the coordinator nodes to establish communication with the libp2p protocol and *AnySync* handshakes, to attempt to execute network configuration requests.

The .zip contains all our tools, but the sync check procedure requires only **“any-sync-netcheck”**.\
(The other file is our [self-hosting tool](https://github.com/anyproto/any-sync-tools/blob/main/any-sync-network/README.md).)
