How To Update Client For Rust Mac

  1. Linux and Mac EAC support is probably too early to reliably use (something garry probably found out after pushing Mac/Linux EAC out). The Windows client has a minor fuckup in the registry keys being set.
  2. This timeline shows the history of the Rust game client updates, so you can track updates history at one place. Additional details of each update.
How To Update Client For Rust Mac

The current idea of RustBuster was to create an Anti-Cheat that is running on client side, with auto-update, obfuscated, and get rid of the server-sided laggy anti cheats. Also, RustBuster client will be a Plugin-Developement Center too, where plugin devs will be able to do client sided GUIs, and stuffs, etc.

A Rust based DNS client, server, and Resolver, built to be safe and secure from theground up.

This repo consists of multiple crates:

LibraryDescription
Proto Raw DNS library, exposes an unstable API and only for use by the other Trust-DNS libraries, not intended for end-user use.
Client Used for sending query, update, and notify messages directly to a DNS server.
Server Use to host DNS records, this also has a named binary for running in a daemon form.
Resolver Utilizes the client library to perform DNS resolution. Can be used in place of the standard OS resolution facilities.
Rustls Implementation of DNS over TLS protocol using the rustls and ring libraries.
NativeTls Implementation of DNS over TLS protocol using the Host OS' provided default TLS libraries
OpenSsl Implementation of DNS over TLS protocol using OpenSSL
  • Build a safe and secure DNS server and client with modern features.
  • No panics, all code is guarded
  • Use only safe Rust, and avoid all panics with proper Error handling
  • Use only stable Rust
  • Protect against DDOS attacks (to a degree)
  • Support options for Global Load Balancing functions
  • Make it dead simple to operate

Client

Using the ClientFuture is safe. ClientFuture is a brand new rewrite of the oldClient. It has all the same features as the old Client, but is written with thewonderful futures-rs library. Please send feedback! It currently does not cacheresponses, if this is a feature you'd like earlier rather than later, post arequest. The validation of DNSSec is complete including NSEC. As of now NSEC3is broken, and I may never plan to support it. I have some alternative ideasfor private data in the zone. The old Client has been deprecated, so pleaseuse the ClientFuture. If this is an inconvenience, I may add a conveniencewrapper around ClientFuture that would match the old Client; if this is somethingyou would like to see, please file an issue.

Unique client side implementations

These are standards supported by the DNS protocol. The client implements themas high level interfaces, which is a bit more rare.

FeatureDescription
SecureSyncClientDNSSec validation
createatomic create of a record, with authenticated request
appendverify existence of a record and append to it
compare_and_swapatomic (depends on server) compare and swap
delete_by_rdatadelete a specific record
delete_rrsetdelete an entire record set
delete_alldelete all records sets with a given name
notifynotify server that it should reload a zone

DNS over TLS on the Client

DNS over TLS is supported. This is accomplished through the use of rust-native-tls. To use DNS over TLS with the Client, the TlsClientConnection should be used. See the TlsClientConnectionBuilder::add_ca() method. Similarly, to use the tokio ClientFuture the TlsClientStream should be used. ClientAuth, mTLS, is currently not supported, there are some issues still being worked on. TLS is supported for Server validation and connection privacy.

Server

The server code is complete, the daemon supports IPv4 and IPv6, UDP and TCP.There currently is no way to limit TCP and AXFR operations, so it is still notrecommended to put into production as TCP can be used to DOS the service.Master file parsing is complete and supported. There is currently no forkingoption, and the server is not yet threaded (although it is implemented withasync IO, so threading may not be a huge benefit). There is still a lot of workto do before a server can be trusted with this externally. Running it behind afirewall on a private network would be safe.

Zone signing support is complete, to insert a key store a pem encoded rsa filein the same directory as the initial zone file with the .key suffix. Note:this must be only readable by the current user. If one is not present one willbe created and written to the correct location. This also acts as the initialkey for dynamic update SIG(0) validation. To get the public key, the DNSKEYrecord for the zone can be queried. This is needed to provide to otherupstream servers to create the DS key. Dynamic DNS is also complete,if enabled, a journal file will be stored next to the zone file with thejrnl suffix. Note: if the key is changed or updated, it is currently theoperators responsibility to remove the only public key from the zone, thisallows for the DNSKEY to exist for some unspecified period of time duringkey rotation. Rotating the key currently is not available online and requiresa restart of the server process.

DNS over TLS on the Server

Support of TLS on the Server is managed through a pkcs12 der file. The documentation is captured in the example test config file, example.toml. A registered certificate to the server can be pinned to the Client with the add_ca() method. Alternatively, as the client uses the rust-native-tls library, it should work with certificate signed by any standard CA.

DNSSec status

Currently the root key is hardcoded into the system. This gives validation ofDNSKEY and DS records back to the root. NSEC is implemented, but not NSEC3.Because caching is not yet enabled, it has been noticed that some DNS serversappear to rate limit the connections, validating RRSIG records back to the rootcan require a significant number of additional queries for those records.

Zones will be automatically resigned on any record updates via dynamic DNS.

Mac OS X: using homebrew

Debian-based (includes Ubuntu & Raspbian): using apt-get

How To Update Client For Rust Macros

Testing

  • Unit tests

    These are good for running on local systems. They will create sockets forlocal tests, but will not attempt to access remote systems. Tests can alsobe run from the crate directory, i.e. client or server and cargo test

  • Functional/Integration tests

    These will try to use some local system tools for compatibility testing,and also make some remote requests to verify compatibility with other DNSsystems. These can not currently be run on Travis for example.

  • Benchmarks

    Waiting on benchmarks to stabilize in mainline Rust.

Building

  • Production build, from the trust-dns base dir

Running

Warning: Trust-DNS is still under development, running in production is notrecommended. The server is currently only single-threaded, it is non-blockingso this should allow it to work with most internal loads.

  • Verify the version
  • Get help
  • Launch named server with test config
  • Query the just launched server with dig

Using as a dependency and custom features

The Client has a few features which can be disabled for different reasons when embedding in other software.

  • dnssec-opensslIt is a default feature, so default-features will need to be set to false (this will disable all other default features in trust-dns). Until there are other crypto libraries supported, this will also disable DNSSec validation. The functions will still exist, but will always return errors on validation. The below example line will disable all default features and enable OpenSSL, remove 'openssl' to remove the dependency on OpenSSL.

  • dnssec-ringRing support can be used for RSA and ED25519 DNSSec validation.

  • dns-over-native-tlsUses native-tls for DNS-over-TLS implementation, only supported in client and resolver, not server.

  • dns-over-opensslUses openssl for DNS-over-TLS implementation supported in server and client, resolver does not have default CA chains.

  • dns-over-rustlsUses rustls for DNS-over-TLS implementation, only supported in client and resolver, not server. This is the best option where a pure Rust toolchain is desired.

  • mdnsEXPERIMENTALEnables the experimental mDNS features as well as DNS-SD.

FAQ

  • Why are you building another DNS server?

    Because of all the security advisories out there for BIND.Using Rust semantics it should be possible to develop a high performance andsafe DNS Server that is more resilient to attacks.
