Installation

From release

To run plik, information technology'south very simple :

$ wget https://github.com/root-gg/plik/releases/download/i.3.v/plik-ane.iii.5-linux-amd64.tar.gz $ tar xzvf plik-1.3.5-linux-amd64.tar.gz $              cd              plik-i.three.five-linux-amd64/server $ ./plikd

Et voilĂ  ! You at present accept a fully functional instance of Plik running on http://127.0.0.1:8080.
You tin edit server/plikd.cfg to conform the configuration to your needs (ports, ssl, ttl, backend params,...)

From sources

To compile plik from sources, you'll demand golang and npm installed on your organisation

Git clone or become become the project and merely run brand :

$ make $              cd              server              &&              ./plikd
Docker

Plik comes with multiarch docker images built for linux amd64/i386/arm/arm64:

  • rootgg/plik:latest (latest release)
  • rootgg/plik:{version} (release)
  • rootgg/plik:dev (latest commit of master)

Meet the Plik Docker reference

Plik as well comes with some useful scripts to test backend in standalone docker instances :

Come across the Plik Docker backend testing

Configuration

The configuration is managed using a TOML file plikd.cfg

Defining configuration parameters using environs variables

I tin can specify configuration parameters using env variable with the configuration parameter in screaming ophidian case

                              PLIKD_DEBUG_REQUESTS=true ./plikd                          

For Arrays and config maps they must be provided in json format. Arrays are overridden just maps are merged

                              PLIKD_DATA_BACKEND_CONFIG='{"Directory":"/var/files"}' ./plikd                          

Information backends

Plik is shipped with multiple data backend for uploaded files and metadata backend for the upload metadata.

  • File databackend :

Store uploaded files in a local or mounted file system directory.

  • Openstack Swift databackend : http://docs.openstack.org/developer/swift/

Openstack Swift is a highly available, distributed, eventually consequent object/hulk shop which supports Server Side Encryption

  • Amazon S3

  • Google Cloud Storage

Metadata backends

  • Sqlite3

Suitable for standalone deployment.

  • PostgreSQL / Mysql

Suitable for distributed / High Availability deployment.

Cli client

Plik is shipped with a powerful golang multiplatform cli client (downloadable in spider web interface) :

              Usage:   plik [options] [FILE] ...  Options:   -h --help                 Show this assist   -d --debug                Enable debug mode   -q --quiet                Enable quiet mode   -o, --oneshot             Enable OneShot ( Each file will be deleted on first download )   -r, --removable           Enable Removable upload ( Each file can be deleted by anyone at anymoment )   -Due south, --stream              Enable Streaming ( It will block until remote user starts downloading )   -t, --ttl TTL             Time earlier expiration (Upload will exist removed in m|h|d)   -n, --name Proper noun           Set file proper name when piping from STDIN   --server SERVER           Overrides plik url   --token TOKEN             Specify an upload token   --comments Annotate        Set comments of the upload ( MarkDown compatible )   -p                        Protect the upload with login and countersign   --countersign PASSWD         Protect the upload with login:password ( if omitted default login is "plik" )   -a                        Archive upload using default annal params ( see ~/.plikrc )   --archive Way            Archive upload using specified archive backend : tar|zip   --compress Manner           [tar] Pinch codec : gzip|bzip2|xz|lzip|lzma|lzop|compress|no   --archive-options OPTIONS [tar|zero] Additional command line options   -s                        Encrypt upload usnig default encrypt params ( see ~/.plikrc )   --not-secure              Practice not encrypt upload regardless of ~/.plikrc configurations   --secure MODE             Archive upload using specified archive backend : openssl|pgp   --aught CIPHER           [openssl] Openssl aught to apply ( see openssl help )   --passphrase PASSPHRASE   [openssl] Passphrase or '-' to be prompted for a passphrase   --recipient RECIPIENT     [pgp] Set recipient for pgp backend ( example : --recipient Bob )   --secure-options OPTIONS  [openssl|pgp] Additional control line options   --update                  Update client   -v --version              Prove client version                          

For instance to create directory tar.gz annal and encrypt it with openssl :

$ plik -a -s mydirectory/ Passphrase              :              30ICoKdFeoKaKNdnFf36n0kMH Upload successfully created              :              https://127.0.0.1:8080/                #/?id=0KfNj6eMb93ilCrl              mydirectory.tar.gz              :              fifteen.70 MB 5.92 MB/due south  Commands              :              curl -south                              'https://127.0.0.ane:8080/file/0KfNj6eMb93ilCrl/q73tEBEqM04b22GP/mydirectory.tar.gz'                            |              openssl aes-256-cbc -d -pass pass:30ICoKdFeoKaKNdnFf36n0kMH              |              tar xvf - --gzip

Customer configuration and preferences are stored at ~/.plikrc or /etc/plik/plikrc ( overridable with PLIKRC environement variable )

Quick upload using curl only

whorl --grade                              'file=@/path/to/file'                            http://127.0.0.1:8080

When Authentication is used and NoAnonymousUploads are enabled yous can quick upload using user tokens:

gyre --grade                              'file=@/path/to/file'                            --header                              'Ten-PlikToken: xxxx-xxx-xxxx-xxxxx-xxxxxxxx'                            http://127.0.0.1:8080

DownloadDomain configuration option must be fix for this to properly piece of work.

Go client

Plik at present comes with a golang library above which the cli client is built

See the Plik library reference

API

Plik server expose a HTTP API to manage uploads and get files :

See the Plik API reference

Admin CLI

Using the ./plikd server binary it'southward possible to :

  • create/list/delete local accounts
  • create/list/delete user CLI tokens
  • create/list/delete files and uploads
  • import / export metadata

Encounter help for more details

Authentication

Plik can cosign users using Local accounts or using Google or OVH APIs.

If source IP address brake is enabled, user accounts tin can simply be created from trusted IPs so authenticated users tin upload files without source IP brake.

It possible to deny unauthenticated uploads totally ( NoAnonymousUploads ).

Admin users can access the admin dashboard and manipulate every uploads.

  • Local :

    • You can dispense local users with the server control line
    $ ./plikd --config ./plikd.cfg user create --login root --name Admin --admin     Generated countersign                  for                  user root is 08ybEyh2KkiMho8dzpdQaJZm78HmvWGC
  • Google :

    • You'll need to create a new application in the Google Developper Panel
    • You'll exist handed a Google API ClientID and a Google API ClientSecret that you'll demand to put in the plikd.cfg file.
    • Do non forget to whitelist valid origin and redirect url ( https://yourdomain/auth/google/callback ) for your domain.
    • Information technology is possible to whitelist merely i or more e-mail domains.
  • OVH :

    • You'll need to create a new application in the OVH API : https://eu.api.ovh.com/createApp/
    • You'll be handed an OVH awarding central and an OVH application cloak-and-dagger key that you'll need to put in the plikd.cfg file.

Once authenticated a user can generate upload tokens that tin can be specified in the ~/.plikrc file to authenticate the control line client.

              Token = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"                          

Security

Plik permit users to upload and serve any content equally-is, simply hosting untrusted HTML raises some well known security concerns.

Plik will try to avoid HTML rendering by overriding Content-Type to "text-evidently" instead of "text/html".

By default Plik sets a couple of security HTTP headers like X-Content-Blazon-Options, X-XSS-Protection, X-Frame-Options, Content-Security-Policy to disable sensible features of most recent browsers similar resource loading, xhr requests, iframes,... This will however suspension features like audio/video playback, pdf rendering so it's possible to disable this behavior by setting the EnhancedWebSecurity configuration parameter to false

Forth with that it is as well strongly advised to serve uploaded files on a split (sub-)domain to fight confronting phishing links and to protect Plik's session cookie with the DownloadDomain configuration parameter.

Cross compilation

All binary are now statically linked. Clients tin can be safely cross-compiled for all bone/architectures as they practise not rely on GCO (sqlite) Servers rely on CGO/sqlite need a cantankerous-compilation gear up environment.

make release volition build release archives for amd64,i386,arm,arm64

To build a release with only specific architectures of the client

                              CLIENT_TARGETS="linux/amd64" releaser/release.sh                          

To build only specific for only specific architectures

                              TARGETS="linux/amd64" releaser/release.sh                          

To build with a specific cross compiler toolchain

                              TARGETS="linux/arm/v6" CC=arm-linux-gnueabihf-gcc releaser/release.sh                          

FAQ

  • Why is stream manner cleaved in multiple instance deployement ?

Beacause stream style isn't stateless. As the uploader asking will block on 1 plik case the downloader request MUST get to the same instance to succeed. The load balancing strategy MUST be aware of this and route stream requests to the same instance by hashing the file id.

Hither is an instance of how to achieve this using nginx and a picayune piece of LUA. Make sure your nginx server is built with LUA scripting support. You might want to install the "nginx-extras" Debian bundle (>ane.7.two) with built-in LUA back up.

              upstream plik {     server 127.0.0.1:8080;     server 127.0.0.ane:8081; }  upstream stream {     server 127.0.0.1:8080;     server 127.0.0.1:8081;     hash $hash_key; }  server {     mind 9000;      location / {         set $upstream "";         gear up $hash_key "";         access_by_lua '             _,_,file_id = string.find(ngx.var.request_uri, "^/stream/[a-zA-Z0-nine]+/([a-zA-Z0-ix]+)/.*$")             if file_id == nil then                 ngx.var.upstream = "plik"             else                 ngx.var.upstream = "stream"                 ngx.var.hash_key = file_id             end         ';         proxy_pass http://$upstream;     } }                          
  • Redirection loops with DownloadDomain enforcement and reverse proxy
              Invalid download domain 127.0.0.i:8080, expected plik.root.gg                          

DownloadDomain check the Host header of the incoming HTTP request, by default reverse proxies similar Nginx or Apache mod_proxy does not forwards this Header. Bank check the following configuration directive :

              Apache mod_proxy : ProxyPreserveHost On Nginx : proxy_set_header Host $host;                          
  • I take an error when uploading from client : "Unable to upload file : HTTP error 411 Length Required"

Nether nginx < 1.3.9, you must enable HttpChunkin module to allow transfer-encoding "chunked".
You might want to install the "nginx-extras" Debian packet with congenital-in HttpChunkin module.

And add together in your server configuration :

chunkin on;              error_page 411 = @my_411_error;              location @my_411_error {         chunkin_resume;              }
  • How to disable nginx buffering ?

By default nginx buffers big HTTP requests and reponses to a temporary file. This behaviour leads to unnecessary disk load and slower transfers. This should be turned off (>1.vii.12) for /file and /stream paths. You might as well want to increase buffers size.

Detailed documentation : http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_buffering

              proxy_buffering off; proxy_request_buffering off; proxy_http_version 1.1; proxy_buffer_size 1M; proxy_buffers 8 1M; client_body_buffer_size 1M;                          
  • Why authentication does not work with HTTP connections when EnhancedWebSecurity is set ?

Plik session cookies take the "secure" flag set when EnhancedWebSecurity is set and so they tin merely be transmitted over secure HTTPS connections.

  • Build failure "/usr/bin/env: 'node': No such file or directory"

Debian users might need to install the nodejs-legacy parcel.

              This bundle contains a symlink for legacy Node.js code requiring binary to be /usr/bin/node (not /usr/bin/nodejs as provided in Debian).                          
  • How to take and upload screenshots like a dominate ?
              allonym pshot="scrot -southward -e 'plik -q \$f | xclip ; xclip -o ; rm \$f'"                          

Requires you lot to accept plik, scrot and xclip installed in your $PATH.
scrot -due south allow you to "Interactively select a window or rectangle with the mouse" then Plik will upload the screenshot and the url volition be direct copied to your clipboard and displayed by xclip. The screenshot is and so removed of your home directory to avoid garbage.

How to contribute to the project ?

Contributions are welcome, experience gratis to open up issues and/or submit pull requests. Please be sure to likewise run/update the test suite :

                              brand fmt     make lint     brand test     make test-backends
