DaviX is a tool for remote I/O, file transfer and file management based on the HTTP protocol.

daviX is used at CERN by several projects, including the ROOT data analysis framework,^[4]^[5] the File Transfer Services (FTS),^[6] the European Middleware Initiative gfal2 library ^[7]^[8] or the dynamic storage federation project.^[9]

Feature support

DaviX supports:

SSL/TLS
User/Password Authentication
X.509 Client certificates authentication
redirection caching
Multi-Range requests (Vector I/O)
checksum calculation
session recycling
VOMS credential
Multi-sources via Metalink.
SOCKS4/5
S3 and WebDAV Operations

Examples of daviX command line use

to Upload a file to a WebDav repository

$ davix-put local_file davs://example.com/folder1/remote_file

to Download a file from a S3 bucket with AWS authentication

$ davix-get—s3secretkey A --s3accesskey B s3://bucket1.s3-instance.com/long/path/remote_file local_file

To list a WebDav repository over https

$ davix-ls davs://example.com/folder1/folder2/

To list an S3 bucket with AWS authentication

$ davix-ls—s3secretkey A --s3accesskey B s3://bucket1.s3-instance.com/

To create a subdirectory over WebDAV

$ davix-mkdir davs://example.com/folder1/folder2/folder4

Execute an HTTP PUT request to a RESTful webservice with the content "hello"

$ davix-http -X PUT—data "hello" http://example.com/rest/api/service
