Our IPC interface supports extra config file, IPC.config that should be put in standard ASF's config directory.
When available, this file specifies advanced configuration of ASF's Kestrel http server, together with other IPC-related tuning. Unless you have a particular need, there is no reason for you to use this file, as ASF is already using sensible defaults in this case.

}Endpoints - This is a collection of endpoints, each endpoint having its own unique name (like example-http4) and Url property that specifies Protocol://Host:Port listening address. By default, ASF listens on IPv4 and IPv6 http addresses, but we've added https examples for you to use, if needed. You should declare only those endpoints that you need, we've included 4 example ones above so you can edit them easier.
Host accepts a variety of values, including * value that binds ASF's http server to all available interfaces. Be extremely careful when you use Host values that allow remote access. Doing so will enable access to ASF's IPC interface from other machines, which may pose a security risk. We strongly recommend to use IPCPassword (and preferably your own firewall too) at a minimum in this case.
KnownNetworks - This variable specifies network addresses which we consider trustworthy. By default, ASF is configured to trust loopback interface (localhost, same machine) only. This property is used in two ways. Firstly, if you omit IPCPassword, then we'll allow only machines from known networks to access ASF's API, and deny everybody else as a security measure. Secondly, this property is crucial in regards to reverse-proxies accessing ASF, as ASF will honor its headers only if the reverse-proxy server is from within known networks. Honoring the headers is crucial in regards to ASF's anti-bruteforce mechanism, as instead of banning the reverse-proxy in case of a problem, it'll ban the IP specified by the reverse-proxy as the source of the original message. Be extremely careful with the networks you specify here, as it allows a potential IP spoofing attack and unauthorized access in case the trusted machine is compromised or wrongly configured.
PathBase - This is base path that will be used by IPC interface. This property is optional, defaults to / and shouldn't be required to modify for majority of use cases. By changing this property you'll host entire IPC interface on a custom prefix, for example http://localhost:1242/MyPrefix instead of http://localhost:1242 alone. Using custom PathBase may be wanted in combination with specific setup of a reverse proxy where you'd like to proxy a specific URL only, for example mydomain.com/ASF instead of entire mydomain.com domain. Normally that would require from you to write a rewrite rule for your web server that would map mydomain.com/ASF/Api/X -> localhost:1242/Api/X, but instead you can define a custom PathBase of /ASF and achieve easier setup of mydomain.com/ASF/Api/X -> localhost:1242/ASF/Api/X.

The following config will allow remote access from all sources, therefore you should ensure that you read and understood our security notice about that, available above.
{
"Kestrel": {
"Endpoints": {
"HTTP": {
"Url": "http://*:1242"

}
}
}If you do not require access from all sources, but for example your LAN only, then it's much better idea to use something like 192.168.0.* instead of *. Adapt the network address appropriately if you use a different one.

้ๅธธ๏ผๆจๆ่ฉฒ้้่จญ็ฝฎAuthenticationๅญๆฎต็ผ้ๅฐๆผๆจ้ ญ็ HTTP ่ซๆฑใ The way of doing that depends on the actual tool you're using for accessing ASF's IPC interface, for example if you're using curl then you should add -H 'Authentication: MyPassword' as a parameter. This way authentication is passed in the headers of the request, where it in fact should take place.
Alternatively you can append password parameter to the end of the URL you're about to call, for example by calling /Api/ASF?password=MyPassword instead of /Api/ASF alone. This approach is good enough, but obviously it exposes password in the open, which is not necessarily always appropriate. In addition to that it's extra argument in the query string, which complicates the look of the URL and makes it feel like it's URL-specific, while password applies to entire ASF API communication.
Both ways are supported and it's totally up to you which one you want to choose. We recommend to use HTTP headers everywhere where you can, as usage-wise it's more appropriate than query string. However, we support query string as well, mainly because of various limitations related to request headers. A good example includes lack of custom headers while initiating a websocket connection in javascript (even though it's completely valid according to the RFC). In this situation query string is the only way to authenticate.
Our IPC interface, in additon to ASF API and ASF-ui also includes swagger documentation, which is available under /swagger URL. Swagger documentation serves as a middle-man between our API implementation and other tools using it (e.g. ASF-ui). It provides a complete documentation and availability of all API endpoints in OpenAPI specification that can be easily consumed by other projects, allowing you to write and test ASF API with ease.
Apart from using our swagger documentation as a complete specification of ASF API, you can also use it as user-friendly way to execute various API endpoints, mainly those that are not implemented by ASF-ui. ็ฑๆผๆๅ็ swagger ๆๆชๆฏๅพ ASF ไปฃ็ขผ่ชๅ็ๆ็๏ผๅ ๆญคๆจๅฏไปฅไฟ่ญๆๆชๅง็ต่ๆจ็ ASF ็ๆฌไธญๅ ๅซ็API็ซฏ้ปไธญ็ๆๆฐๆๆชไฟๆๅๆญฅใ
ASF by default listens only on localhost addresses, which means that accessing ASF IPC from any other machine but your own is impossible. Unless you modify default endpoints, attacker would need a direct access to your own machine in order to access ASF's IPC, therefore it's as secure as it can be and there is no possibility of anybody else accessing it, even from your own LAN.
However, if you decide to change default localhost bind addresses to something else, then you're supposed to set proper firewall rules yourself in order to allow only authorized IPs to access ASF's IPC interface. In addition to doing that, you will need to set up IPCPassword, as ASF will refuse to let other machines access ASF API without one, which adds another layer of extra security. You may also want to run ASF's IPC interface behind a reverse proxy in this case, which is further explained below.

ทไพ่จชๅๅฎใ Local userscripts follow CORS logic, and we allow access from all origins for them (*), as long as IPCPassword is set, as an extra security measure. This allows you to execute various authenticated ASF API requests, without allowing potentially malicious scripts to do that automatically (as they'd need to know your IPCPassword to do that).
Yes, we recommend to use a reverse proxy for that. This way you can access your web server in typical way, which will then access ASF's IPC on the same machine. Alternatively, if you don't want to run with a reverse proxy, you can use custom configuration with appropriate URL for that. For example, if your machine is in a VPN with 10.8.0.1 address, then you can set http://10.8.0.1:1242 listening URL in IPC config, which would enable IPC access from within your private VPN, but not from anywhere else.

</IfModule>Yes, you can achieve it through two different ways. A recommended way would be to use a reverse proxy for that, where you can access your web server through https like usual, and connect through it with ASF's IPC interface on the same machine. This way your traffic is fully encrypted and you don't need to modify IPC in any way to support such setup.
Second way includes specifying a custom config for ASF's IPC interface where you can enable https endpoint and provide appropriate certificate directly to our Kestrel http server. This way is recommended if you're not running any other web server and don't want to run one exclusively for ASF. Otherwise, it's much easier to achieve a satisfying setup by using a reverse proxy mechanism.
Starting with ASF V5.1.2.1, we've added additional security measure that, by default, allows only loopback interface (localhost, your own machine) to access ASF API without IPCPassword set in the config. This is because using IPCPassword should be a minimum security measure set by everybody who decides to expose ASF interface further. You're still able to override this decision by specifying the networks which you trust to reach ASF without IPCPassword specified, you can set those in KnownNetworks property in custom config. However, unless you really know what you're doing and fully understand the risks, you should instead use IPCPassword as declaring KnownNetworks will allow everybody from those networks to access ASF API unconditionally.
