Profiles can be kept in step across machines through any folder they
share (cloud drive, network share, git checkout): one file,
nexus-profiles.nexus, in the encrypted-export format under a sync
password kept in the keychain/vault. Each sync merges profile by profile
(newest updated_at wins), propagates deletions as dated tombstones (an
edit after a deletion brings the profile back; tombstones expire after
180 days), validates every incoming profile, writes the file only when
it changed, and never syncs credentials.
Settings → Security → Profile sync picks the folder and sets the
password; syncs run at launch, 3 s after a profile change, every 10
minutes and on Sync Now (automatic runs stay quiet unless something
changed). An end-to-end test drives create, edit and delete between two
data directories sharing a folder.
Registration now opens with CAP LS 302 (servers without IRCv3 ignore it
and register as before). From the offered capabilities (multi-line LS
lists included) the client requests server-time and, when the profile
enables it, sasl; then AUTHENTICATE PLAIN with the account (defaulting
to the nick) and a stored SASL password (irc-sasl-password), base64 in
400-byte chunks, and CAP END on success or failure — failures are shown
on the Server tab and the connection carries on (NickServ still works).
server-time tags stamp events with the server's clock, so replayed
history shows real times.
Tested against the fake IRC server: multi-line LS, REQ/ACK, the PLAIN
exchange, 903, CAP END, and a tagged message's timestamp.
- Host certificates: certificate authorities are trusted per OpenSSH host
pattern (stored as @cert-authority known-hosts rows, matched against
'host' or '[host]:port' as OpenSSH does, with *, ? and !). For a host a
CA covers, the client asks for a certificate; one signed by a matching
CA, of host type, naming the host and in date is trusted without a
first-use prompt, and anything else is refused. Hosts no CA covers keep
the existing key checks. Applies to jump hosts and tunnels too.
- User certificates: <key>-cert.pub next to the configured private key is
used for publickey login (falling back to the plain key).
- Settings → Known Hosts: import ~/.ssh/known_hosts (hashed names and
@revoked lines skipped and counted), export in OpenSSH format, and a
Trust a CA form.
Verified against OpenSSH sshd with ssh-keygen-issued certificates: host
cert accepted without prompting and user-cert login with only
TrustedUserCAKeys; a CA for other hosts falls back to the key check; a
different CA is refused.
The tab layout (tab order and names, pins, the active tab, split trees
with their ratios) is saved whenever it changes — checked once a second,
written only on change, so it survives a crash — and reopened at the
next launch: saved profiles reconnect and local shells start in the
directory they were in (on Linux the live /proc cwd, so it isn't one
command behind). Quick Connect tabs and placeholder panes are skipped.
A General setting turns it off; it never runs when launched with
--connect, --run-local or --open, and screenshot runs never save.
Verified: a local tab left in /usr/share came back there with a
'Restored 1 tab(s)' toast.
Images sent with the iTerm2 inline protocol (imgcat and friends) are
decoded (PNG, JPEG, GIF first frame) and drawn at the cursor, sized from
the width/height arguments in cells, pixels or percent (aspect kept,
never wider than the terminal); the cursor moves below so text
continues after them. They are anchored to the same stable line index
as the shell-integration marks, scroll with the text and are dropped
with the scrollback or on clear.
Remote data, so decoding is bounded (8192 px a side, 256 MiB
allocation), OSC bodies are capped at 16 MiB, inline=0 downloads are
ignored, and each terminal keeps at most 32 Mpx of images, oldest
first. Sixel and kitty graphics are not implemented.
Cells carrying an OSC 8 hyperlink get a dotted underline, and Ctrl/Cmd+
click opens the link. Because a link's text can say anything, hovering
one always shows its real target (and says when it won't be opened).
Both OSC 8 and plain-text URLs now open through the web-only check, so
remote output can't launch file:, ftp: or custom-scheme handlers (plain
text ftp:// links used to be opened).
Terminals now pick up OSC 133 prompt/command/output/finished marks,
which the VT parser ignores: a scanner (app/src/osc.rs, split-safe
across reads, bodies capped at 4 KiB) finds them in the output stream
and each mark records the cursor line. Lines are stable indexes that
account for lines a full scrollback rotates out, so marks stay on their
text; clearing the scrollback drops them.
With marks present: Ctrl/Cmd+Shift+Up/Down and Previous/Next Prompt in
the context menu jump between prompts, Copy Last Command Output copies
what the last finished command printed, and a green/red bar beside each
prompt shows the exit status (hover for code and duration). OSC 7
working-directory reports are parsed too (used by the next change).
The manual shows bash and zsh snippets; fish 4 and common prompt themes
already send the marks.
An RDP profile can name a Kerberos KDC; CredSSP then authenticates with
Kerberos instead of NTLM, reaching the KDC through a small TCP client
(RFC 4120 length-prefixed framing, 5 s connect / 10 s read timeouts,
replies capped at 1 MiB so a hostile KDC can't force a huge allocation).
UDP KDCs are refused with a clear message. Tested against a fake KDC
(round trip, oversized reply, UDP); not against a real realm.
Smart-card logon is not implemented: it needs PC/SC hardware and a card
to build and test against.
RDP profiles can go through a Remote Desktop Gateway (MS-TSGU over an
HTTPS WebSocket) with its own username and password, stored like other
credentials (rdp-gateway-password). The gateway stream is bridged to a
loopback socket so the blocking RDP client uses it like any transport.
IronRDP's gateway crate (0.0.1) is vendored with fixes: it used
ironrdp-tls, which accepts any certificate, before sending Basic
credentials — the gateway is now verified against the web PKI; its
asserts on gateway-supplied lengths are errors instead of panics; and
the server port is passed through. Checked against a self-signed
openssl s_server: the connection is refused ('invalid peer certificate')
before any request or credential is sent. Not tested against a real
gateway; Basic-auth gateways only (no NTLM).
An optional 'Nexus Terminal' printer (IronRDP's PostScript driver
announce) appears on the remote desktop; each job is written to
'Nexus print <time>.ps' in Downloads, with a toast saying where. Jobs
are capped at 256 MiB and empty jobs leave no file. The shared drive and
the printer now share one RDPDR backend (rdp_devices); the printer
works on every platform, the drive on Linux and macOS.
Tested with a unit test driving create/write/close; xrdp has no printer
redirection, so not exercised against a server.
- Audio: the RDPSND channel with IronRDP's cpal playback backend (PCM;
Opus left out to avoid another native library). On by default for new
RDP profiles. Building now needs the ALSA headers on Linux
(libasound2-dev), added to CI, release and fuzz jobs and the build docs.
- Shared folder (Linux/macOS): one local folder appears on the remote
desktop as a drive. IronRDP's native backend joins server paths onto
the share unchecked, so it is wrapped in ConfinedDrive: create, list
and rename paths with '..' components, NUL bytes, or that resolve
through a symlink outside the share are refused (ACCESS_DENIED);
tests cover the escapes.
Verified against xrdp (with FUSE): the remote read the shared file, and
writes, mkdir and rename landed in the local folder. Not verified:
audio playback (the test container has no sound module), and xrdp lists
the drive as 'ignored' and can't list its directories (an IronRDP/xrdp
naming and listing mismatch, fixed upstream for the name).
A CLIPRDR channel with a text-only backend (CF_UNICODETEXT): text copied
on the remote desktop is fetched and goes through the app's remote-
clipboard preference like VNC and OSC 52; local text is offered to the
remote when the desktop gains focus, on Ctrl+V and with Paste Clipboard
(which no longer types the text). Backend callbacks run inside the
active stage, so they queue requests that the session loop sends.
Verified against xrdp: the remote X clipboard read back the offered
text, and a remote copy arrived through on_clipboard.
- Protocol::Rdp with RdpConfig (domain, password mode, certificate
policy, TLS-only fallback, fixed or tab-sized resolution, SOCKS5/HTTP
proxy, SSH tunnel); migration 008 adds rdp_config and drops the
protocol CHECK constraint so new protocols no longer need a rebuild.
- Session manager: connect_rdp dials directly, via the shared proxy
module (proxy password from the secret store) or an SSH tunnel; the
server certificate goes through the known-hosts check (key type
rdp-tls); a tab-sized desktop uses the tab's reported pixel size, and
resizes wait until the server opens Display Control. Rejected NLA
passwords count as auth failures, so a saved one is asked again.
- The VNC viewer becomes DesktopView for both protocols; a small adapter
turns its keysyms and pointer masks into RDP scancodes, Unicode keys,
buttons and wheel events. For RDP, Paste Clipboard types the text.
- Profile editor RDP section, Quick Connect, badges, docs.
Verified against xrdp in the app: logon, desktop, input, and connections
through SOCKS5 and HTTP CONNECT relays. Not verified here: Windows/NLA
servers, the SSH tunnel route, and Display Control resizing (xrdp
0.9.24 never opened the channel).
The Go-generated link.db, profiles.link and rec1.cast fixtures and the
tests that read them are removed. Their coverage is kept by tests on
data this build writes: a fresh database round-trips SSH profiles (env
vars, login scripts, forwards), serial profiles, IRC room state, known
hosts, snippets and preferences, and encrypted exports round-trip and
reject a wrong password. The import dialog no longer offers .link files
and the docs stop mentioning them.
OSC 52 and VNC ServerCutText now go through one handler that honours
'allow remote clipboard' and always toasts the first line, so a silent
clipboard swap can't set up a paste into another shell (SEC-20261012-010).
Multi-line pastes into a terminal without bracketed paste ask first, with a
preview (SEC-20261012-017). The launch-time update check can be turned off
and the updater docs no longer claim it is opt-in; the unused GitHub
fallback is removed (SEC-20261012-013, F15).
Renames the product across the codebase: Go module path, config/data
paths, keychain service name, export file extension, build tooling,
docs, and UI text. Sidebar brand mark now reads ">_ AlchementaryLink"
with "Alchementary" in the connection-group gold accent colour, and
the window title is "Alchementary Link".
