After installation

Your sign-in addresses, the first steps to do once on a new server, and the files worth knowing.

The server is ready to use as soon as the installer prints its summary. Work through this page once, then create your first customers.

Your addresses

Service	Address	Who uses it
Server Admin	`https://server.yourdomain.com:8443`	administrators and staff
Control Panel	`https://panel.yourdomain.com:8443`	hosting customers
Reseller Panel	`https://reseller.yourdomain.com:8443`	resellers
HF Files	`https://files.yourdomain.com`	customers' website files
HF Studio	`https://db.yourdomain.com`	customers' databases
HF Mail	`https://webmail.yourdomain.com`	mailboxes
API	`https://api.yourdomain.com:2087/v1`	billing systems, scripts and the desktop app (a browser gets 403)
Mail apps	incoming `imap.yourdomain.com` (IMAP 993, POP3 995), outgoing `smtp.yourdomain.com` (587 STARTTLS, 465 SSL)	mailboxes
FTP / SFTP	`ftp.yourdomain.com` (port 21 with TLS) / port 22	customers

The panels open with the port (:8443) only. The same names without the port send visitors to your website. Each panel has its own sign-in: a customer who opens the Server Admin address is told where to go instead.

The same addresses are in the "server is ready" email sent to the administrator's address. It may land in spam until SPF, DKIM and the reverse DNS are set.

First steps

Sign in to Server Admin at https://server.yourdomain.com:8443 with the admin login you created.
Add the DNS records still missing. The summary listed them; hf-panel dns-setup --check shows them again. Names that point at the server join the SSL certificate by themselves within 5 minutes. You don't need to run anything again. See DNS setup.
Set the reverse DNS (PTR) of the server's IP to mail.yourdomain.com at your server provider.
Open Server Admin › Server › Server health and fix anything shown in yellow or red: certificate, DNS, PTR, firewall, disk, services. Many items have a one-click fix.
Check Server Admin › Email › Mail health. SPF, DKIM and DMARC should be green before you send mail to customers.
Switch on two-factor login for your own login: your username at the top right › Password & security.
Look at the admin mailbox admin@yourdomain.com in HF Mail: sign in at https://webmail.yourdomain.com with the full address and the password from /root/hostfog-mailboxes.txt, or click Webmail next to it under Server Admin › Email › Server mailboxes. The role addresses postmaster@, abuse@, hostmaster@, webmaster@, dmarc@, tls@ and security@ forward to the administrator's email; that screen shows them, and Server Admin › System › Settings sets where they go.
Set up backups under Server Admin › System › Backups and Backup storage: how often, how many to keep, and a copy on another server or in cloud storage.
Check your licence under Server Admin › Billing › Licence. See Licensing.
Create your first package and hosting account. See the Quick start.

Tip: take a snapshot of the server at your provider once it is set up. It is the "known good" state you can go back to.

Check the server from the command line

bash

hf-panel health              # services, configuration, disk, memory, SSL, clock, mail queue
hf-panel dns-setup --check   # the DNS records, as public DNS sees them
hf-panel portals             # each panel's address, DNS and SSL

Files worth knowing

File	What it holds
`/var/log/hostfog-install.log`	everything the installer ran
`/root/hostfog-mailboxes.txt`	the passwords of the mailboxes the installer made (root only)
`/etc/hostfog/dns-setup.zone`	the server domain's DNS records, ready to import at a DNS provider
`/etc/hostfog/config.json`	the panel's settings
`/etc/hostfog/VERSION`	the installed HF Panel version

Locked out?
