Overview
This interface lists your server’s services and allows you to enable and monitor them.
Important:
The server profile that you select in WHM’s Server Profile interface (WHM » Home » Server Configuration » Server Profile) affects which services display in this interface. For more information, read our How to Use Server Profiles documentation.
Note:
Select the Enabled checkbox to enable a specific service.
- Select the Monitor checkbox to monitor a specific service in the cPanel interface.
- To monitor a service, you must first enable it.
TailWatch Drivers in the tailwatchd module
| Driver | Description |
|---|---|
| APNSPush | This driver notifies iOS® devices when new mail arrives. |
| ChkServd | This driver monitors the services that you configure in the Service Manager interface.
|
| Eximstats | This driver tracks Exim mail statistics. The Eximstats driver maintains the email bandwidth logs, limits email usage, and populates data for the Mail Delivery Reports system. |
| JailManager | This driver manages the jailshells that the EXPERIMENTAL: Jail Apache Virtual Hosts using mod_ruid2 and cPanel® jailshell setting in WHM’s Tweak Settings interface (WHM » Home » Server Configuration » Tweak Settings) uses. The JailManager driver updates each user’s jailshell with the root filesystem.
Note:
If the EXPERIMENTAL: Jail Apache Virtual Hosts using mod_ruid2 and cPanel® jailshell setting is disabled, the system disables the JailManager option.
|
| MailHealth | This driver monitors the mail log for the Dovecot mail services’ memory status. The system administrator receives a message if Dovecot is out of memory. |
| ModSecLog | This driver parses the ModSecurity® audit log and stores the information in the modsec database. |
| RecentAuthedMailIpTracker | This driver tracks the IP addresses for recently-authenticated IMAP and POP3 sessions. |
| cPBandwd | This driver generates the bandwidth logs for the IMAP and POP3 mail services. |
Service daemons
Note:
The server’s installed services and the server’s profile determine which daemons this interface displays.
- For more information about server profiles, read our How to Use Server Profiles documentation.
- For more information about service status, read our Service Status documentation.
| Daemon | Description |
|---|---|
ClamAV Daemon (clamd) |
This daemon scans your server for malicious programs.
Note:
This service only appears if you install the ClamAV for cPanel plugin in WHM’s Manage Plugins interface (WHM » Home » cPanel » Manage Plugins).
|
cpanel-dovecot-solr |
This daemon enables IMAP Full-Text Search (FTS) Indexing (powered by Apache Solr™), which provides fast search capabilities for IMAP mailboxes. For more information about this service, read our The install_dovecot_fts Script documentation.
Note:
|
PHP-FPM service for cPanel Daemons (cpanel_php_fpm) |
This daemon improves the performance of PHP-based internal applications that ship with cPanel & WHM, such as:
Note:
This daemon will accelerate a maximum of ten concurrent processes per user.
|
cPanel DAV Daemon (cpdavd) |
This daemon enables a set of extensions that allow users to manage their websites, calendars, and contacts remotely.
Important:
If you plan to host other people’s websites or email on your web server, do not disable this daemon.
Note:
The Database and DNS server profiles disable this daemon.
|
cPanel Greylisting Daemon (cpgreylistd) |
This daemon manages Greylisting, a service that protects your server against spam from sources that your server does not recognize. For more information, read our Greylisting documentation.
Note:
The Database and DNS server profiles disable this daemon.
|
cPHulk Daemon (cphulkd) |
This daemon manages cPHulk Brute Force Protection, a service that provides protection for your server against brute force attacks. |
Cron Daemon (crond) |
This daemon manages cron job scheduling. For more information, read our Cron Jobs documentation.
Note:
On Debian® systems, such as Ubuntu®,
cron is the daemon’s name. The restartsrv script’s crond service manages Ubuntu’s cron daemon.
|
cPanel DNS Admin Cache (dnsadmin) |
This daemon runs as a standalone daemon. This improves speed, but increases it memory usage. Deselect this option if you wish to use multiple dnsadmin processes for zone-related actions. |
Exim Mail Server (exim) |
This daemon is the part of your mail server that sends and receives mail. We recommend that you monitor and enable this daemon for most servers.
Warning:
If you disable this daemon, the following settings do not appear in the Mail section of WHM’s Tweak Settings interface (WHM » Home » Server Configuration » Tweak Settings):
|
Exim Mail Server (on another port) (exim-altport) |
This daemon allows you to configure Exim to listen to an additional port. By default, Exim listens to the following ports:
Note:
In the text box, enter the additional port number on which you wish to allow Exim to run.
|
FTP Server (ftpd) |
This daemon runs your FTP server.
Important:
We strongly recommend that you monitor this daemon.
Note:
|
Apache Web Server (httpd) |
This daemon processes HTTP requests from visitors. Enable this feature to host websites on your web server.
Note:
The Database, DNS, and Mail server profiles disable this daemon.
|
IMAP Server (imap) |
This daemon for Dovecot processes how your users download their mail. For more information, read our IMAP vs. POP3 documentation.
Important:
We strongly recommend that you monitor this daemon.
Note:
The Database and DNS server profiles disable this daemon.
|
IP Aliases (ipaliases) |
This daemon allows you to add more than one IP address to your network adapter. The system stores IP addresses that you add in WHM’s Add a New IP Address interface (WHM » Home » IP Functions » Add a New IP Address) in the /etc/ips file. The ipaliases service activates those IP addresses when the server starts. Use this configuration to run multiple connections on a single network, where each connection serves an additional purpose. |
LMTP Server (lmtp) |
This daemon allows Exim to connect to the Dovecot mail server. |
Mailman (mailman) |
This daemon allows your users to create a single email address to send mail to multiple email addresses. For more information, read our Mailing Lists documentation.
Note:
|
Database Server (mysql or mariadbd) |
This daemon processes database queries. If you plan to host any content management systems or applications that require a database, enable this daemon or the PostgreSQL Server daemon.
Important:
We recommend that you monitor this daemon. The system does not monitor this daemon by default.
Note:
The Mail server profile disables this daemon.
|
DNS Server (named) |
This daemon runs the nameservers.
Note:
|
NGINX® Server (nginx) |
This daemon runs the reverse proxy and caching server.
Note:

Important:
We strongly recommend that you only enable this service on servers with at least 1,000 MB of available memory.
|
Passive OS Fingerprinting Daemon (p0f) |
This daemon reports the visitor’s operating system and other information for email notifications that the system administrator requests in WHM’s Contact Manager interface (WHM » Home » Server Contacts » Contact Manager). This information helps a system administrator quickly identify visitors that trigger events that cause alerts. The spam prevention and cPHulk systems use this information to identify potential spammers and brute force attacks. For example, if a user logs in to a server from multiple locations and uses multiple operating systems, this may indicate that someone has compromised the user’s account. For more information about this daemon, read the Passive OS Fingerprinting documentation at GitHub.
Note:
If you disable this daemon, the notification footers will no longer contain the visitor information.
|
POP3 Server (pop) |
