- Add a TOC to the Local IPs page. - Increase the echo delay in our speaker audio page to 1.5s. This sounds much better and is less clashy than 1s. Also add a sleep(0) (eww, I know) to fix timeouts on some browsers/computers. - Move Lua feature compat to a new "reference" section. Still haven't figured out how to structure these docs - open to any ideas really. - Mention FFmpeg as an option for converting to DFPWM (closes #1075). - Allow data-mount to override built-in files. See my comment in #1069.

# Allowing access to local IPs
|
|
By default, ComputerCraft blocks access to local IP addresses for security. This means you can't normally access any
|
|
HTTP server running on your computer. However, this may be useful for testing programs without having a remote
|
|
server. You can unblock these IPs in the ComputerCraft config.

|
|
- [Minecraft 1.13 and later, CC:T 1.86.2 and earlier](#cc-1.86.2)
|
|
- [Minecraft 1.12.2 and earlier](#mc-1.12)
|
|
|
|
## Minecraft 1.13 and later, CC:T 1.87.0 and later {#cc-1.87.0}
|
|
The configuration file can be located at `serverconfig/computercraft-server.toml` inside the world folder on either
|
|
single-player or multiplayer. Look for lines that look like this:
|
|
|
|
```toml
|
|
#A list of rules which control behaviour of the "http" API for specific domains or IPs.
|
|
#Each rule is an item with a 'host' to match against, and a series of properties. The host may be a domain name ("pastebin.com"),
|
|
#wildcard ("*.pastebin.com") or CIDR notation ("127.0.0.0/8"). If no rules, the domain is blocked.
|
|
[[http.rules]]
|
|
host = "$private"
|
|
action = "deny"
|
|
```
|
|
|
|
On 1.95.0 and later, this will be a single entry with `host = "$private"`. On earlier versions, this will be a number of
|
|
`[[http.rules]]` with various IP addresses. You will want to remove all of the `[[http.rules]]` entires that have
|
|
`action = "deny"`. Then save the file and relaunch Minecraft (Server).
|
|
|
|
Here's what it should look like after removing:
|
|
|
|
```toml
|
|
#A list of rules which control behaviour of the "http" API for specific domains or IPs.
|
|
#Each rule is an item with a 'host' to match against, and a series of properties. The host may be a domain name ("pastebin.com"),
|
|
#wildcard ("*.pastebin.com") or CIDR notation ("127.0.0.0/8"). If no rules, the domain is blocked.
|
|
[[http.rules]]
|
|
#The maximum size (in bytes) that a computer can send or receive in one websocket packet.
|
|
max_websocket_message = 131072
|
|
host = "*"
|
|
#The maximum size (in bytes) that a computer can upload in a single request. This includes headers and POST text.
|
|
max_upload = 4194304
|
|
action = "allow"
|
|
#The maximum size (in bytes) that a computer can download in a single request. Note that responses may receive more data than allowed, but this data will not be returned to the client.
|
|
max_download = 16777216
|
|
#The period of time (in milliseconds) to wait before a HTTP request times out. Set to 0 for unlimited.
|
|
timeout = 30000
|
|
```
|
|
|
|
## Minecraft 1.13 and later, CC:T 1.86.2 and earlier {#cc-1.86.2}
|
|
The configuration file for singleplayer is at `.minecraft/config/computercraft-common.toml`. Look for lines that look
|
|
like this:
|
|
|
|
```toml
|
|
#A list of wildcards for domains or IP ranges that cannot be accessed through the "http" API on Computers.
|
|
#If this is empty then all whitelisted domains will be accessible. Example: "*.github.com" will block access to all subdomains of github.com.
|
|
#You can use domain names ("pastebin.com"), wilcards ("*.pastebin.com") or CIDR notation ("127.0.0.0/8").
|
|
blacklist = ["127.0.0.0/8", "10.0.0.0/8", "172.16.0.0/12", "192.168.0.0/16", "fd00::/8"]
|
|
```
|
|
|
|
Remove everything inside the array, leaving the last line as `blacklist = []`. Then save the file and relaunch Minecraft.

|
|
blacklist = []
|
|
```
|
|
|
|
## Minecraft 1.12.2 and earlier {#mc-1.12}
|
|
On singleplayer, the configuration file is located at `.minecraft\config\ComputerCraft.cfg`. On multiplayer, the
|
|
configuration file is located at `<server folder>\config\ComputerCraft.cfg`. Look for lines that look like this:
|
|
|
|
```ini
|
|
# A list of wildcards for domains or IP ranges that cannot be accessed through the "http" API on Computers.
|
|
# If this is empty then all explicitly allowed domains will be accessible. Example: "*.github.com" will block access to all subdomains of github.com.
|
|
# You can use domain names ("pastebin.com"), wildcards ("*.pastebin.com") or CIDR notation ("127.0.0.0/8").
|
|
S:blocked_domains <
|
|
127.0.0.0/8
|

10.0.0.0/8
|

|
192.168.0.0/16
|
|
fd00::/8
|
|
>
|
|
```
|
|
|
|
Delete everything between the `<>`, leaving the last line as `S:blocked_domains = <>`. Then save the file and relaunch
|
|
Minecraft (Server).
