Configure the Peer Crawler

By default, rippled servers provide statistics publicly to anyone who asks using the peer crawler API, to make it easier to track the health and topology of the XAG Ledger's peer-to-peer network. You can configure your server to provide more or less information, or to reject peer crawler requests entirely.

This document contains steps for two options:

Change the Information Reported by the Peer Crawler
Disable the Peer Crawler

Change the Information Reported by the Peer Crawler

To configure how much information your server provides in response to peer crawler requests, complete the following steps:

Edit your rippled's config file.
```
vim /etc/opt/ripple/rippled.cfg
```
The recommended installation uses the config file /etc/opt/ripple/rippled.cfg by default. Other places you can put a config file include $HOME/.config/ripple/rippled.cfg (where $HOME is the home directory of the user running rippled), $HOME/.local/ripple/rippled.cfg, or the current working directory from where you start rippled.
Add or update the [crawl] stanza in your config file, and save the changes:
```
[crawl]
overlay = 1
server = 1
counts = 0
unl = 1
```
The fields in this stanza control which fields the server returns in the peer crawler response. The names of the config fields match the fields of the API response. A setting with a value of 1 means to include the field in the response. A value of 0 means to omit that field from the response. This example shows the default values for each setting.
After saving the changes to the config file, restart your rippled server to apply the updated configuration:
```
systemctl restart rippled
```

Disable the Peer Crawler

To disable the peer crawler API on your server, so it does not respond to peer crawler requests at all, complete the following steps:

Edit your rippled's config file.
```
vim /etc/opt/ripple/rippled.cfg
```
The recommended installation uses the config file /etc/opt/ripple/rippled.cfg by default. Other places you can put a config file include $HOME/.config/ripple/rippled.cfg (where $HOME is the home directory of the user running rippled), $HOME/.local/ripple/rippled.cfg, or the current working directory from where you start rippled.
Add or update the [crawl] stanza in your config file, and save the changes:
```
[crawl]
0
```
Remove or comment out all other contents of the crawl stanza.
After saving the changes to the config file, restart your rippled server to apply the updated configuration:
```
systemctl restart rippled
```
