Enable Capture Through the UI

To enable this feature, you must have passwordless root SSH access from the HST server to all agents in the cluster. (Otherwise, you must use the HST Agent CLI Capture).

To configure HST for web UI capture, follow these steps:

Edit the /etc/hst/conf/hst-server.ini file. The [client] section contains two properties that need to be updated to enable remote capture:
```
[client]
; thread pool maximums
threadpool.size.max=50
; Password-less SSH enabled or not
password_less_ssh.enabled=
; SSH key for data capture
sshkey.path=
```
- Set the password_less_ssh.enabled property to true in an SSH environment that uses a single private key on the HST server, with the corresponding public key distributed in the authorized_keys file on all HST agents.
- You can use the sshkey.path property in an SSH environment in which there is a distributed private key on all HST agents. For this scenario, the property should be set to the path of the private key to be used. For example: /root/.ssh/id_rsa.
After you have updated the appropriate properties, restart the HST server:
```
# hst restart
```
