Appendix - technical information

Maintainers note: this user manual focuses on station operation and the web interface. For a detailed HERMES system architecture and software stack description (e.g. uucpd/uuport, sbitx_controller, modem/TNC integration, and systemd service orchestration), see the document “HERMES Software Description” (software_en.pdf) in the HERMES documentation repository.

Network Information

Each HERMES system provides a WiFi access point. The configuration is:

• WiFi Network Name: HERMES
• WiFi Password: amazonia

The IP of the HERMES station (in the wireless interface) is 10.0.0.1 and the ethernet connection will connect as a dhcp client to an already existing network.

Network Services

E-mail services

The e-mail settings are the following:

• Server address: hermes (IP 10.0.0.1)
• SMTP (Simple Mail Transfer Protocol): port 25
• SMTPS (Secure Simple Mail Transfer Protocol): port 465, with SSL support (used for DeltaChat, the certificates are valid until 2031)
• IMAP (Internet Message Access Protocol): port 143
• Webmail URL acessible: http://hermen/mail or http://10.0.0.1/mail

These settings should not be needed by most users as DeltaChat automatically identifies all the settings by entering just the e-mail address and password at the login prompt.

Web services

The HERMES web interface runs on port 80 on http, and provides these capabilities:

• BBS P2P public messaging capability (over UUCP);
• E-mail user administration;
• UUCP queue management;
• HF radio transceiver management tools;
• Customized permissions for users send multimedia messages;
