From 79d157664868ae594274b0086d01ddf142bef806 Mon Sep 17 00:00:00 2001 From: Aaron Raimist Date: Thu, 5 Dec 2019 00:07:15 -0600 Subject: [PATCH] Allow Synapse manhole to be enabled Can you double check that the way I have this set only exposes it locally? It is important that the manhole is not available to the outside world since it is quite powerful and the password is hard coded. --- group_vars/matrix_servers | 3 +++ roles/matrix-synapse/defaults/main.yml | 14 +++++++++++++- .../templates/synapse/homeserver.yaml.j2 | 8 +++++--- .../synapse/systemd/matrix-synapse.service.j2 | 3 +++ 4 files changed, 24 insertions(+), 4 deletions(-) diff --git a/group_vars/matrix_servers b/group_vars/matrix_servers index 3b31bcaa..aa2d0b75 100755 --- a/group_vars/matrix_servers +++ b/group_vars/matrix_servers @@ -574,6 +574,9 @@ matrix_synapse_container_federation_api_tls_host_bind_port: "{{ '8448' if (matri # # For exposing the Synapse Metrics API's port (plain HTTP) to the local host. matrix_synapse_container_metrics_api_host_bind_port: "{{ '127.0.0.1:9100' if (matrix_synapse_metrics_enabled and not matrix_nginx_proxy_enabled) else '' }}" +# +# For exposing the Synapse Manhole port (plain HTTP) to the local host. +matrix_synapse_container_manhole_api_host_bind_port: "{{ '127.0.0.1:9000' if matrix_synapse_manhole_enabled else '' }}" matrix_synapse_database_host: "{{ matrix_postgres_connection_hostname }}" matrix_synapse_database_user: "{{ matrix_postgres_connection_username }}" diff --git a/roles/matrix-synapse/defaults/main.yml b/roles/matrix-synapse/defaults/main.yml index 03776f66..54df32c7 100644 --- a/roles/matrix-synapse/defaults/main.yml +++ b/roles/matrix-synapse/defaults/main.yml @@ -40,6 +40,13 @@ matrix_synapse_container_federation_api_tls_host_bind_port: '' # Takes an ":" or "" value (e.g. "127.0.0.1:9100"), or empty string to not expose. matrix_synapse_container_metrics_api_host_bind_port: '' +# Controls whether the matrix-synapse container exposes the manhole port (tcp/9000 in the container). +# +# Takes effect only if the manhole is enabled (matrix_synapse_manhole_enabled). +# +# Takes an ":" or "" value (e.g. "127.0.0.1:9100"), or empty string to not expose. +matrix_synapse_container_manhole_api_host_bind_port: '' + # A list of extra arguments to pass to the container matrix_synapse_container_extra_arguments: [] @@ -222,10 +229,15 @@ matrix_synapse_push_include_content: true matrix_synapse_url_preview_enabled: true # Enable exposure of metrics to Prometheus -# See https://github.com/matrix-org/synapse/blob/master/docs/metrics-howto.rst +# See https://github.com/matrix-org/synapse/blob/master/docs/metrics-howto.md matrix_synapse_metrics_enabled: false matrix_synapse_metrics_port: 9100 +# Enable the Synapse manhole +# See https://github.com/matrix-org/synapse/blob/master/docs/manhole.md +matrix_synapse_manhole_enabled: false + + # Send ERROR logs to sentry.io for easier tracking # To set this up: go to sentry.io, create a python project, and set # matrix_synapse_sentry_dsn to the URL it gives you. diff --git a/roles/matrix-synapse/templates/synapse/homeserver.yaml.j2 b/roles/matrix-synapse/templates/synapse/homeserver.yaml.j2 index 5d2846ef..67798c72 100644 --- a/roles/matrix-synapse/templates/synapse/homeserver.yaml.j2 +++ b/roles/matrix-synapse/templates/synapse/homeserver.yaml.j2 @@ -229,11 +229,13 @@ listeners: compress: false {% endif %} +{% if matrix_synapse_manhole_enabled %} # Turn on the twisted ssh manhole service on localhost on the given # port. - # - port: 9000 - # bind_addresses: ['::1', '127.0.0.1'] - # type: manhole + - port: 9000 + bind_addresses: ['0.0.0.0'] + type: manhole +{% endif %} ## Homeserver blocking ## diff --git a/roles/matrix-synapse/templates/synapse/systemd/matrix-synapse.service.j2 b/roles/matrix-synapse/templates/synapse/systemd/matrix-synapse.service.j2 index a19cbe19..0bd2c25d 100644 --- a/roles/matrix-synapse/templates/synapse/systemd/matrix-synapse.service.j2 +++ b/roles/matrix-synapse/templates/synapse/systemd/matrix-synapse.service.j2 @@ -41,6 +41,9 @@ ExecStart=/usr/bin/docker run --rm --name matrix-synapse \ {% if matrix_synapse_metrics_enabled and matrix_synapse_container_metrics_api_host_bind_port %} -p {{ matrix_synapse_container_metrics_api_host_bind_port }}:{{ matrix_synapse_metrics_port }} \ {% endif %} + {% if matrix_synapse_manhole_enabled and matrix_synapse_container_manhole_api_host_bind_port %} + -p {{ matrix_synapse_container_manhole_api_host_bind_port }}:9000 \ + {% endif %} -v {{ matrix_synapse_config_dir_path }}:/data:ro \ -v {{ matrix_synapse_run_path }}:/matrix-run:rw \ -v {{ matrix_synapse_storage_path }}:/matrix-media-store-parent:slave \
