Project.delete() calls open() to rebuild the internal data structures
needed for cleanup. open() schedules start_all() when the project has
auto_start enabled, so deleting an auto-start project actually launched
every node process, allocating ports and consuming resources, only for
close() to kill them moments later.
open() now takes an auto_start argument (default True, so normal opens
are unchanged) and delete() passes auto_start=False.
Fixes#2784
The condition 'state != "stopped" or state != "exited"' is a tautology,
so the state check was a no-op and a stop request was sent even for a
container that had already exited.
_get_container_state() never returns "stopped" (only "running",
"paused" or "exited"), so the intended negation of the condition used in
_fix_permissions() requires 'and', not 'or' (De Morgan's law).
Added a regression test asserting no stop query is issued for an
already-exited container.
When a Docker container with the same name already exists (e.g., from a
previous crashed GNS3 session), Docker returns a 409 Conflict error
when trying to create a new container with that name. This causes the
project open operation to fail.
This fix adds automatic cleanup of stale containers when encountering
a name conflict:
- Added DockerHttp409Error exception class
- Updated http_query to detect 409 status codes
- Modified create() to remove conflicting containers and retry
Fixes the issue where opening a project fails with:
"Docker has returned an error: 409 Conflict. The container name
'/GNS3.xxx' is already in use by container 'xxx'"
Previously the disconnected compute check ran after open(), which would
block for 120s trying to connect to unreachable remote computes before
rejecting the deletion. Now reads the topology file directly to extract
compute IDs and checks connectivity before calling open(), enabling
immediate rejection of deletions involving offline computes.
Also removes the redundant post-open() check since the early check
covers both opened and closed project states.

The run() cleanup block was guarded by `except (ConnectionError, OSError):`,
so exits via asyncio.CancelledError or any other exception type skipped
cleanup. Result: `_reader_process` stays pinned to the dead reader and
`_get_reader()` returns None for every subsequent client — the silent-proxy
symptom described in #2344.
Convert the except block to try/finally so cleanup always runs, regardless
of how `_process()` exits. Also:
- catch asyncio.CancelledError + generic Exception (with log.exception) so
unexpected failures don't swallow the cleanup
- reset `_current_read = None` after cancellation
- use `dict.pop(..., None)` instead of `del` to avoid KeyError races if
the broadcast loop's timeout handler already removed the entry
Triggering pattern observed in practice: a diagnostic tool opens a console,
sends a few commands, and closes abruptly (e.g. from a test harness or
orchestration script that cancels its Task). If the `_process()` task was
awaiting on one of the `network_read` / `reader_read` futures at the time
of cancellation, the CancelledError propagates up through `run()` and
bypasses the ConnectionError-only except clause. The proxy accepts future
connections (the listen socket is still alive) but never forwards any data
because `_reader_process` never got reset.
Validated against gns3/gns3-server:latest (2.2.56.1) running a 10-scenario
sequential regression batch that previously hung reliably on the 4th
sp_v1 / L3VPN scenario and now completes cleanly across all 10.
- Catch OSError alongside ConnectionError in connection processing to handle more network errors
- Move client_info retrieval inside try block to prevent AttributeError on failed connections
- Replace bare except with specific exceptions (OSError, ConnectionError, asyncio.TimeoutError)
- Improve error logging to include specific exception details and client information
- filter incoming cursor position report sequences (`ESC[<row>;<col>R`) in `AsyncioTelnetServer`
- prevent stray `;1R;80R` characters on late telnet console attach after VM boot
- keep QEMU serial transport unchanged (`-serial telnet`) for BIOS compatibility
On musl-based systems (Alpine), ldd returns exit code 0 for static
binaries, unlike glibc which returns 1. This causes install_busybox()
to reject all busybox binaries as "dynamically linked" on Alpine.
Fix by also accepting binaries whose executable name contains "static"
(i.e. busybox-static, busybox.static), which are the first two
candidates checked by the function. The generic "busybox" fallback
still relies on the ldd return code check.
* Use apt-add-repository to install repository
* Add option to not upgrade the system
* Check if Python version is >= 3.9 when installing from ppa-v3 repository
Set tcp keepalive timers to 60 seconds. Seems to default to 2 hours on ubuntu 22. Most firewalls will age out an idle tcp session at 1 hour.
Will not address telnet console failing after a tcp session has failed (TimeoutError).
Removed an extra slash at the end when setting the user home directory. This was causing unexpected behavior for other scrips as ~ was aliased to /opt/gns3/ instead of the expected /opt/gns3.
This caused an extra / to appear in commands unexpectedly.

The release cycle of NixOs is around every half of the year.
On the unstable channel you have the latest gns3-server version.
Do not worry to use unstable because it mostly just the latest stable version. You can also do overlays to keep your other systems pkgs on the regular release version.
Changes to remote-install to make it compatible with the latest versions of ubuntu server. Also adds an option to install the welcome dialog from gns3vm
In reference to bug #1918, the gns3.service.systemd file references ExecPath /usr/bin/gns3server which needs to be changed to /usr/local/bin/gns3server for the daemon/service to run without failure.
Please see the change I made to the service above.
Remove check for open project. Without this check a remote can be rebooted and will be usable once the main server polls it again. Without this the main server would need to open a project that already uses the remote server or restart the main server's gns3 process.
using --no-cache-dir flag in pip install ,make sure downloaded packages
by pip don't cached on system . This is a best practice which make sure
to fetch from repo instead of using local cached one . Further , in case
of Docker Containers , by restricting caching , we can reduce image size.
In term of stats , it depends upon the number of python packages
multiplied by their respective size . e.g for heavy packages with a lot
of dependencies it reduce a lot by don't caching pip packages.

When `--with-iou` and `--with-openvpn` are both enabled, hostname
were updated in `/etc/hostname` but not on the running system (only
changed after reboot). So the old hostname were used in MOTD and
client OpenVPN config URL.
Some cloud providers (example, AWS EC2 for non-metal instances) do not
support nested virtualization, as well as some hypervisors (example,
VirtualBox prior to 6.x, Hyper-V on AMD). Option `--without-kvm` can
be used to disable hardware acceleration in these scenarios. Otherwise,
user will receive error when trying to start Qemu-based devices.
Commit also: replace `enable_kvm` and `require_kvm` with newer config
options (`enable_hardware_acceleration` and
`require_hardware_acceleration`); and do some code refactors.
One can argue that, instead of prividing option `--without-kvm`, we
should check if system supports KVM and enable/disable hardware
acceleration accordingly. However, there is the case when the
hypervisor supports nested virtualization, but feature is just disabled.
The chosen approach for this case is to keep KVM enabled and let user
known (user will eventually receive an error) so user can fix it.
Otherwise, user might never know and suffer from performance
degradation.
Fail-safe: use "ide" if an image is set but no interface type is configured.
Use the HDA disk interface type if none has been configured for HDD.

There's currently no clipboard support for servers running on TigerVnc. TigerVnc clipboard support is provided by vncconfig that needs to be spawned for every display socket. The code changes above provides that functionality
An application ID is used by IOU to generate its interface Mac addresses. They must be unique across all opened projects sharing the same computes to avoid Mac address collisions.
A fixed id doesn't hurt and now we can select Disk Interface=none in
GNS3 and e.g. attach the volume as a USB thumb drive with -device
usb-storage,drive=drive0,...
docker user to root for the init script to configure the network,
then drops to the configured user (or root if one is not defined)
for continuing booting the image.
