domain's Issues

It returns gibberish

I want to retrieve only MX

    let mut core = Core::new().unwrap();
    let resolv = Resolver::new(&core.handle());
    let name = DNameBuf::from_str("www.rust-lang.org.").unwrap();

    let mx_req = resolv.query((name, Rtype::Mx, Class::In));
    let mx = core.run(mx_req).unwrap();

    for record in mx.answer().unwrap() {
        println!("{}", record.unwrap());
    }

But the answer contains only CNAME.
Also, why does it require the dot in the end of a URL? Otherwise it panics at runtime.

error: Could not compile `domain`.

The tokio-core downloaded by cargo automatically is v0.1.6.
The environment i'm using is
4.8.0-41-generic #44~16.04.1-Ubuntu
cargo 0.19.0-nightly (c995e9eb5 2017-03-17)

Any plans to publish on crates.io?

Hi,

I'm experimenting with domain as a part of my effort to make generic/pluggable name resolution for tokio. It would be easier to play with the library if it was published on the crates.io.

So are there issues with that?

Crashed in Query

I have received some reports of crashes at https://github.com/partim/domain/blob/master/src/resolv/public.rs#L306

error: Could not compile `domain`.

Limit iteration for decompressing domain names

Compressed domain names can have infinite loops. The easiest way to avoid hanging on them is to add a counter and stop decompression at around 10,000 steps or so.

`DNameBuf::with_capactity` misspelled

It should be with_capacity, of course.

Resolver configuration on Windows

The resolver configuration is currently read only from /etc/resolv.conf which won’t work on Windows.

Since I don’t have access to a Windows machine, some help is necessary.

Name compression must consider case

When comparing domain names for deciding whether to compress the rest of the name or not, the case of ASCII letters in the name must be considered in order for the decompressed name to be identical to the original one.

Hint: use a Vec<u8> as the key into the map, not a DNameBuf. This may break for binary labels, but so what.

Not support local hosts file?

for linux: /etc/hosts

Query DNS records directly?

Is there a way to query DNS records directly without futures?

Just want to directly look up the CNAME , A, AAAA, etc for a host so I can trace through them by hand. (working on a DNS mapping tool)

Change master file scanner to operate on `char`.

The scanner currently operates on u8 directly assuming ASCII-compatible encodings of master files. This may not be true on Windows.

Change the scanner to operate on char, reading its data from a Iterator<Item=char>.

Setting DNS information for Windows

get list of windows adapters:
netsh interface show interface

Which will show the name under the "Interface Name" column (shown here in bold):

`Admin State State Type Interface Name

Enabled Connected Dedicated Ethernet
`
add dns server to an interface:

netsh interface ipv4 add dnsserver "Ethernet" address=192.168.x.x index=1

Help on using netsh int ipv4 set dns

`C:\Users\User>netsh int ipv4 set dns help

Parameters:

Tag Value
name - The name or index of the interface.
source - One of the following values:
dhcp: Sets DHCP as the source for configuring DNS
servers for the specific interface.
static: Sets the source for configuring DNS servers
to local static configuration.
address - One of the following values:
: An IP address for a DNS server.
none: Clears the list of DNS servers.
register - One of the following values:
none: Disables Dynamic DNS registration.
primary: Register under the primary DNS suffix only.
both: Register under both the primary DNS suffix, as
well as under the connection-specific suffix.
validate - Specifies whether validation of the DNS server setting
will be performed. The value is yes by default.

Remarks: Sets DNS server configuration to either DHCP or static mode. Only
when source is 'static', is the 'addr' option also available for
configuring a static list of DNS server IP addresses for the
specified interface. If Validate switch is yes, then
the newly set DNS server is validated.

Examples:

set dnsservers name="Wired Ethernet Connection" source=dhcp
set dnsservers "Wired Ethernet Connection" static 10.0.0.1 primary
