First, it is not necessary to use PT-plugin from ready-to-go Guix package. It is possible to download PT-plugin source code and compile it directly, say, somewhere in $HOME folder. The corresponding configuration may look like this (service tor-service-type (config-file (plain-file "torrc" ".... Bridge obfs4 ...")) (transport-plugin (local-file "/home/..../lyrebird" #:recursive? #t))) But this will not necessary work. The reason why it can fail is somewhat interesting. As we know, the tor process, thanks to the 'least-authority-wrapper', is run inside a container, which, in particular, means it has very limited view of the file system. But PT-plugin executable is linked dynamically by default and has its dependency libraries inaccessible from within the container. However, if PT-plugin is linked statically, the configuration above will work. Similarly, if PT-plugin is specified as a direct string path to the store item like this (transport-plugin "/gnu/store/..../bin/lyrebird") it may not work for the same reason. However, if a file-like object is used instead like this (transport-plugin (file-append PT-PACKAGE "/bin/lyrebird")) all the dependencies of PT-PACKAGE are added automatically to the list of allowed paths inside the container (this is provided by the call to 'references-file' from inside 'least-authority-wrapper' procedure). As for me this means that the suggested patch fits very well to the guix'y way of doing things. Regards, Nigko

This patch not only creates new tor-service-type configuration options but, which is crucial, adds pluggable transport (PT) executable, if provided, to #:mappings argument of the least-authority-wrapper, see 'tor-shepherd-service' chunk. With this patch Tor process gets access to PT plugin and, if bridges are configured via config-file field, Tor starts using obfuscated traffic. > Even if it had succeeded though, I'm not sure if this is the best > approach to it, since it would break guix system configuration, > right? No, the patch does not break any existing tor-service-type configuration. If PT is not used, 'transport-plugin' defaults to '#f', and the Tor works exactly as if there wasn't any patch at all. > How would one know beforehand which binary to point to? One would > first need to install the PT and look to its path on store and then > link to it in a new configuration. And then this link would have to > be manualy updated. Am I missing something here? There is much simpler and convenient way of doing this. If users want to bring PT into action, they may simply write (service tor-service-type (config-file ".... Bridge obfs4 ...") (transport-plugin (file-append PT-PACKAGE "/bin/name-of-executable")) The PT-PACKAGE does not even have to be present in the list of 'operating-system 'packages field, since Guix will find the reference to PT-package and install it automatically. The only thing which should be known beforehand is the "name-of-executable". For 'go-gitlab-torproject-org-tpo-anti-censorship-pluggable-transports-lyrebird package it is "lyrebird", while for 'go-github-com-operatorfoundation-obfs4 it is "obfs4proxy". It is unlikely that these names will change with upgrades. > Finally, next time, try to keep the issue to a single thread.

I can confirm that the tor service is unable to fork-exec a pluggable-transport and the bootstrap process is halted at its start when trying to use a system wide bridge + PT. However, this patch does not seem to address the issue at hand, since it just creates new tor-service-type configuration options that accomplish the same as configuring on config-file directly. Have you had success with this? I had no luck.

How would one know beforehand which binary to point to? One would first need to install the PT and look to its path on store and then link to it in a new configuration. And then this link would have to be manualy updated. Am I missing something here? Finally, next time, try to keep the issue to a single thread. I'm replying to #70332 and #70302 just for reference, but let's keep to #70341 going forward. Cheers!

There are several types of pluggable transports, e.g., obfs4 (lyrebird), meek, Snowflake etc. There are pluggable transport plugins in guix repo: go-gitlab-torproject-org-tpo-anti-censorship-pluggable-transports-lyrebird go-github-com-operatorfoundation-obfs4 This commit adds the following #:-fields to tor-configuration record type: transport-plugin? - /path/to/transport/plugin/binary (string) (default #f) pluggable-transport - type of pluggable transport (string) (default "obfs4") Since tor process is run by shepherd service inside Linux namespaces, we need to add path to transport plugin to the list of file system mappings in the argument of list-authority-wrapper function. Pluggable transports do not work without bridges, which can be obtained from the official site https://bridges.torproject.org/. The user should specify bridges in #:config-file field of the tor-configuration record. For expample obfs4 bridges are specified as follows Bridge obfs4 ... Bridge obfs4 ...
