- Choosing a vault while the screen was busy went through a gate that did nothing, so the members
panel kept showing the previous vault's people under the new name. The read now starts regardless;
the selection generation discards answers for an earlier choice.
- Locking or signing out from Settings left the window in settings mode under the lock card, with no
title bar to drag, minimise or close, and unlock returned to Settings. Leaving the unlocked state
leaves Settings and closes the members panel; Escape closes that panel before leaving Settings.
- Both importers reported success when the keychain was busy and skipped the batch, or failed partway.
ImportOutcome now carries refused hosts and why a batch stopped, and the screens say so.
- Host cards: the sync badge took 70 of 214 pixels from the name ("bastion" drew as "bast…", two k8s
workers both as "k8s…"); it now sits on the address line. Tag chips wrap and trim inside the card.
Keychain names trim inside their column instead of printing over TYPE, and the Security page's
caption wraps inside its card.
- The Windows CNG key and the macOS keychain tag were one name for every profile, so signing out of
the nightly deleted the key the release build's device unlock was sealed to. DeviceKeyNames keeps the
existing name for the default profile and gives every other profile its own; sign-out deletes only
its own key, and a profile sealed before this keeps reading the shared one.
- DevicePinWindow named two palette resources that do not exist and loaded itself with
AvaloniaXamlLoader.Load, which never assigns the named fields, so it threw on construction and no
PIN prompt was ever shown. A layout test now builds it against the real palette.
- A message larger than the 64 KiB receive buffer was skipped and its tail dispatched as a frame of its
own. Messages are now reassembled up to 16 MiB; one beyond that is dropped whole.
- Input frames are handed to the pump without waiting, and ShellStream takes no lock around its write
buffer, so a snippet's text and its carriage return could interleave or lose bytes. Writes are
serialised per pump in arrival order.
- A resize reaching a shell SSH.NET had already disposed threw out of the receive loop and closed the
socket every tab shares. Each frame's failure now stays with its session.
- Pull hydrated every historical change entry with the item's current ciphertext under that entry's
old revision. The AAD binds the revision, so a client opened it at the wrong version, failed, and
parked its own pending edit as undecryptable. Entries an item has since moved past are left out; the
later entry carries the same payload under the right number, and a fresh device no longer downloads
an item once per edit it ever had.
- Deleting a team's last vault archived the team whoever deleted it, so an admin could archive it out
from under its owner. Only the owner's delete archives it now, and TeamService.ArchiveAsync checks.
- UserStatus was checked nowhere on the request path. ActiveAccountRequirement on both policies answers
403 account-not-active for a suspended or deprovisioned account.
- The hourly last-seen update moves xmin under the tracked user, and enrolment then saved that user
against the stale token: a 500 for anybody enrolling more than an hour after first signing in. The
entity is reloaded after the update.
- The outbox coalesces a new save into the row a push already read, under a new operation id, but
Complete, Revise and Park found the row by sequence alone. The acknowledgement of the earlier state
deleted the row holding the later one and the edit was gone without a word. They now take the
PendingOperation and act only while the row still holds it; a later edit is rebased onto the version
just accepted, so it pushes cleanly instead of conflicting with its own earlier save.
- A pull filtered by type moves the cursor past changes of types it did not ask for, so a build that
added a type (SpelunkKey, ObjectStore) never received the items of that type made before it.
sync_state.pulled_types records the list a cursor was read under, and a different list starts the
pull over once. Migration AddSyncStatePulledTypes.
- A remote name went straight into Path.Combine. A POSIX name may hold backslashes, a colon or a drive
letter, and an S3 key may hold "../", so a name chosen by whoever could write to the host decided
where on this machine a download landed. LocalDirectory.ChildPath cleans the name and requires the
resolved parent to be the target folder; every download path and EDIT use it, and a name that cannot
be a file there is left on the host and reported.
- EDIT handed the copy to the shell's default action, which for .bat, .hta, .js and friends is to run
it. LocalEditor opens such a file with its own "edit" verb or Notepad on Windows and `open -t` on
macOS, and refuses a .desktop launcher on Linux.
- A failed bucket upload leaves its part object, and a retry asked for an offset no bucket accepts, so
the row could never finish. IRemoteFileStore.CanWriteFromAnOffset is false for buckets and the queue
starts those over.
- The SFTP host picker re-found its selection from the empty moment of every vault reload and landed
on the first host once a minute; the chosen host is now remembered, and a typed password is only
sent to the host it was typed for.
Pins are stored per algorithm, so an endpoint pinned for ssh-ed25519 that was answered with only an
ECDSA or RSA key found no pin and raised SshHostKeyUnknownException: the first-use question, where a
pin exists to produce a hard refusal. Anybody in the middle needed nothing more than a key of a
different type.
The connection factory now reads every pin for the endpoint before the handshake, offers the pinned
algorithms first so a server that still holds its pinned key negotiates it, and in the gate accepts a
key under an unpinned algorithm only when its fingerprint matches one of the endpoint's pins (one RSA
key signs as rsa-sha2-256 and rsa-sha2-512). Anything else is a mismatch. IKnownHostStore gains
FindForEndpointAsync for this.
Settings → Security gains a SPELUNK section: an API address and a key, saved as a new keychain item, a Spelunk key (SyncEntityType 14, AadResourceType 17, server table spelunk_key via the AddSpelunkKeyItem migration). It is ciphertext only on the server, lives in the personal vault, syncs like every secret, and holds the key together with the one address it may be sent to. The key box empties once saved; the list shows name, address and how many hosts use each key, never the key. Saving a key for an address that already has one replaces it, and deleting goes through the shared confirmation card with the hosts that would stop connecting.
A host's route names a saved key where it named a credential, in the same apiKeyCredentialId field, so no host schema changes and an older build reads such a host as one whose key credential has gone. At connect a saved key is sent only to its own address; a host naming it with another Spelunk address is refused in words. Keys kept as a credential's password still work. The editor offers saved keys first and picks the one saved for an address as it is typed.
A link from a Spelunk with a saved key now connects straight away, including the first one: saving the key is the user's say-so that the first-link editor used to ask for.
The address and key merge as one pair, so two concurrent edits can never pair one device's key with another's address, and the key never reaches the conflict log.
A Spelunk route can now say that Spelunk signs the user in. Each connection makes a throwaway Ed25519 key pair in memory, sends the public half with the ticket request ({"signIn":{"publicKey":...}}), and logs in as the account Spelunk names (root when it names none) with that key, over the agent's one-connection sshd. Such a host needs no username, key, credential or typed password: the editor greys the login out and saves none, the password box and sheet stay down, and shells, file transfer and port forwards all take the key and account from the route. The flag is nested in the spelunk object at host schema version 10; hosts without it keep their version-9 bytes.
A dodossh://spelunk/connect link now connects: to the personal vault's host tagged spelunk for that server, or, when a saved host already sends an API key to that Spelunk, to a new sign-in host saved in the personal vault with that key and the spelunk tag (made if missing). Only the first link from a Spelunk opens the editor, pre-filled with sign-in ticked and the tag on, so the key credential is chosen once and never sent to an address no saved host already sends it to.
git.dodotech.cloud/dodotech-public/dodossh-api, under the repository's owner, the way Spelunk publishes its images. REGISTRY_USERNAME and REGISTRY_PASSWORD now have to be a Gitea account and a package token for that owner.
The API Dockerfile copied four of the five root build files before restoring and left out Directory.Build.targets, which pins Microsoft.NET.ILLink.Tasks. The image's locked-mode restore therefore asked for whatever ILLink its SDK bundled, and when sdk:10.0-noble moved to 10.0.401 (ILLink 10.0.12) it failed with NU1004 against lock files that correctly say 10.0.11 - while ci.yml, which sees the pin, stayed green.
A server Spelunk manages runs Spelunk's agent, which keeps a connection open
to Spelunk. A host can now be marked "Connect through Spelunk": a connect
asks Spelunk for a ticket, opens a WebSocket, and the agent connects to the
SSH server on the machine's own loopback, so the server needs no open SSH
port. Shells and file transfers both go this way.
Client, in Client.Session:
- SpelunkTunnel implements Spelunk's contract: POST
{api}/api/servers/{id}/tunnel-tickets with the API key as a bearer token
and {"port":N}, then a WebSocket to the API's own origin at the path
Spelunk returns, offering spelunk.tunnel.v1 and ticket.<ticket>. After the
upgrade the relay's RelayBridge carries the bytes unchanged. Every refusal
is a sentence: 401 key, 403 role (with Spelunk's detail), 404 server, 503
agent not connected, 401/503 on the upgrade, and close codes 4502 (agent
could not reach the port, or is too old: "Unknown stream kind") and 4503
(agent disconnected). Only a path is taken from the ticket response, so it
cannot send the ticket to another host.
- IConnectionRoute is what RelayRoute and SpelunkTunnelRoute have in common,
so the connect path has one shape for both.
Host model: HostSecret.Spelunk is a SpelunkRoute (normalised API base,
server id, and the id of the credential holding the API key), at payload
schema version 8. It is written last and only when present, so every other
host keeps its bytes and its version; an older build reads a Spelunk host
as read-only rather than dropping the route. A half-written route makes the
item unreadable instead of dialled. It merges as one value and is exclusive
with RelayEnabled. The API address must be https, or http to loopback.
The API key is an ordinary keychain credential whose password is the key,
referenced by id, so it is encrypted, synced, merged and rotated like every
other secret, one credential serves every server in the organisation, and
the used-by list and deletion warning count it.
Routing: OpenRouteAsync is the one decision for both transports. A Spelunk
host is never dialled directly, never probed after a failure, and a route
that hung up with a reason replaces SSH.NET's transport error.
UI: a "Connect through Spelunk" card beside the relay card in the desktop
drawer and the phone's editor; ticking one unticks the other.
dodossh://spelunk/connect?api=&server=&name=&host= links:
- SpelunkLink parses them strictly and never reads a credential from one.
- Program reads a link from the arguments; a launch that finds DodoSSH
running passes it down the doorbell as "dodossh.open-link <link>", which
the running instance parses again, bounded, and otherwise ignores whole.
The plain come-forward ring is unchanged.
- A saved host routed to that server on that Spelunk is connected to;
otherwise the editor opens on a new, unsaved Spelunk host, with the key
pre-chosen only when another host already sends it to that Spelunk. A link
that arrives while locked waits for the unlock.
- Windows registers the scheme under HKCU from Velopack's install and update
hooks and removes it on uninstall only if it still points at this
executable; the macOS plist template declares CFBundleURLTypes and the app
takes the URL from Avalonia's activation event; the Linux desktop entry
gets %u and MimeType=x-scheme-handler/dodossh.
The Android head skipped a host's forwards because it had nowhere to show
what was listening. Its terminal bar now draws a ⇄ for a tab that has
forwards, carrying the listening count in green and turning the danger
colour when one failed, and it raises a sheet over the same rows the
desktop sidebar lists: notation, route, state, failure reason and a tap
to switch each off or on. MainWindowViewModel.StartForwards no longer
returns early on Android.
The sheet is shell state like the connect sheet: it collapses the
renderer while up, is lowered by leaving the terminal, and the back
gesture closes it first.
Forwards ride the shell's keep-alive rather than holding the foreground
service themselves, since a forward cannot outlive its shell. They only
change the notification, which now counts ports forwarded beside shells
connected, fed by a new ForwardsChanged event and ListeningForwardCount.
The phone still has no editor for forwards; the More screen card, README
and design-import-gaps now say they run here and are edited on the
desktop.
A host can now carry port forwards (-L, -R, -D), saved inside its
encrypted payload as RelayTicketRequest.PortForwardId already assumed,
so they sync and merge per forward like tags and pinned paths. The host
schema moves to version 8 only for hosts that carry forwards.
ISshConnection gains StartForwardAsync over SSH.NET's forwarded ports.
Every listener binds loopback and there is no bind-address field: a
forward is something any member of a shared keychain can edit. A remote
forward's target is resolved here, IPv4 first, rather than by SSH.NET's
constructor, which takes the first DNS answer and can send ::1.
Forwards start with every terminal opened to the host and stop with its
connection; a reconnect starts them again. The session sidebar lists
them with state, failure reason and an on/off switch, the status bar
counts the listening ones, and the host editor and detail pane gain a
PORT FORWARDS section. A forward that cannot start fails alone.
The phone does not start forwards yet: it has no surface showing what
is listening, and its More screen now says so. No byte counts, since
SSH.NET keeps none.
