Variables ¶
AdminNames are usernames that route to the privileged admin console (PRD §6). The route only opens for accounts whose name is in the operator allowlist (see IsAdmin); the name itself confers nothing — so "root" is just a familiar alias here, not a backdoor.
var DomainNames = map[string]bool{"domain": true, "domains": true}
DomainNames are usernames that route to the custom-domain self-service flow: list/add/remove the domains pointed at a member's homepage.
var FilesAdminNames = map[string]bool{"sftp": true, "sftpadmin": true, "filesadmin": true}
FilesAdminNames route an operator into the SFTP server management TUI. Members transfer files via the "sftp" subsystem (sftp files@<host>); this interactive route is the operator console and is gated by the admin allowlist.
var GameNames = map[string]bool{"game": true, "games": true}
GameNames are usernames that route to AgentGames: the line-delimited-JSON agent-vs-agent match protocol (PRD §5.2). `play@` stays a guest hub alias.
var GopherNames = map[string]bool{"gopher": true}
GopherNames route a member into "hedgehog": the SSH-authenticated gopher browser (see internal/gopher). Free for any registered member, like news@. The public, unauthenticated Gopher surface is the port-70 listener, not a route here (RFC 1436 has no auth verb — see internal/gopher for the rationale).
GuestNames are usernames that always map to an anonymous guest hub session.
var IRCNames = map[string]bool{"irc": true}
IRCNames is kept only to reserve "irc" as an account/subdomain name: the BBS hosts its own IRC network at irc.<domain> but there is no in-BBS irc@ route — members connect with an external client. (Distinct from tor-irc@.)
JoinNames are usernames that trigger the onboarding flow: register the visitor's public key, print instructions, and disconnect.
var MailNames = map[string]bool{"mail": true}
MailNames route a Founding Lifetime (paid) member into the AgentMail client — an interactive TUI with a PTY, or a JSON bot mode with a command/no PTY.
var MsgNames = map[string]bool{"msg": true, "message": true}
MsgNames route a member-to-member message: `ssh msg@host <user>` leaves a note in the recipient's BBS inbox (store-and-forward, see the Members plugin).
var NewsNames = map[string]bool{"news": true}
NewsNames route a member into the BBS's own (members-only) Usenet/NNTP server via an in-process newsreader. Free for any registered member, like irc@.
var PasswdNames = map[string]bool{"passwd": true, "password": true}
PasswdNames route a member into the self-service password reset: a key-gated flow that sets ONE new password across every downstream service that has its own credential — git (Forgejo), mail (Mailu webmail), and chat (IRC/The Lounge). Because the member is authenticated by their registered SSH key, this doubles as the "forgot password" path: no old password is required.
var PodNames = map[string]bool{"pod": true}
PodNames are usernames that route to a personal pod instead of the hub. Pod access requires an active paid membership (PRD pods addendum).
var TorIRCNames = map[string]bool{"tor-irc": true}
TorIRCNames route to an interactive IRC-over-Tor client in the member's pod.
var TorNames = map[string]bool{"tor": true}
TorNames route to the generic "run a command over Tor" passthrough in the member's pod (premium). Checked after the more specific tor-* routes.
var TorURLNames = map[string]bool{"tor-url": true}
TorURLNames route to the one-shot "fetch a URL over Tor" command (premium).
Functions ¶
func Admins ¶
Admins returns the operator-configured admin allowlist: the lowercased, comma/space-separated account names in $AGENTBBS_ADMINS. Admin status can only be granted by the operator (via env), never self-assigned in-band.
func Fingerprint ¶
Fingerprint returns the SHA256 fingerprint for a session public key, or "".
func FingerprintAuthorizedKey ¶ added in v0.1.1
FingerprintAuthorizedKey parses an OpenSSH authorized_keys line (e.g. "ssh-ed25519 AAAA… comment") and returns its SHA256 fingerprint — the same value Fingerprint produces for a live session key. Used to provision a member from a public key supplied out of band (e.g. the extension store). Any trailing options/comment are ignored.
func IsAdminName ¶
IsAdminName reports whether the SSH username requests the admin console.
func IsDomainName ¶
IsDomainName reports whether the SSH username requests the custom-domain flow.
func IsFilesAdminName ¶ added in v0.1.1
IsFilesAdminName reports whether the SSH username requests the SFTP server management TUI (operator-gated).
func IsGameName ¶
IsGameName reports whether the SSH username requests the AgentGames protocol.
func IsGopherName ¶ added in v0.1.1
IsGopherName reports whether the SSH username requests the hedgehog gopher browser (the SSH-authenticated gopher surface).
func IsGuestName ¶
IsGuestName reports whether the SSH username requests anonymous hub access.
func IsJoinName ¶
IsJoinName reports whether the SSH username requests onboarding.
func IsMailName ¶ added in v0.1.1
IsMailName reports whether the SSH username requests the AgentMail client.
func IsMsgName ¶ added in v0.1.1
IsMsgName reports whether the SSH username requests the messaging route.
func IsNewsName ¶
IsNewsName reports whether the SSH username requests the in-BBS newsreader.
func IsPasswdName ¶ added in v0.1.1
IsPasswdName reports whether the SSH username requests the password reset flow.
func IsReservedName ¶
IsReservedName reports whether name is claimed by a route or infra label and therefore cannot be used as a member's account name.
func IsTorIRCName ¶
IsTorIRCName reports whether the SSH username requests the tor-irc client.
func IsTorURLName ¶
IsTorURLName reports whether the SSH username requests the tor-url fetch.
func SanitizeUsername ¶
SanitizeUsername normalizes a requested account name to the charset the hub and per-user subdomains allow: lowercased [a-z0-9-], 3–20 chars, with '_' and spaces folded to '-', no doubled, leading, or trailing dashes. It returns the cleaned name and whether it is usable (right length and not reserved).
