SYNOPSIS         top

       systemd-journal-upload.service

       /usr/lib/systemd/systemd-journal-upload [OPTIONS...]
                                               [-u/--url=URL]
                                               [SOURCES...]

DESCRIPTION         top

       systemd-journal-upload will upload journal entries to the URL
       specified with --url=. This program reads journal entries from
       one or more journal files, similarly to journalctl(1). Unless
       limited by one of the options specified below, all journal
       entries accessible to the user the program is running as will be
       uploaded, and then the program will wait and send new entries as
       they become available.

       systemd-journal-upload.service is a system service that uses
       systemd-journal-upload to upload journal entries to a server. It
       uses the configuration in journal-upload.conf(5). At least the
       URL= option must be specified.

OPTIONS         top

       -u, --url=[https://]URL[:PORT], --url=[http://]URL[:PORT]
           Upload to the specified address.  URL may specify either just
           the hostname or both the protocol and hostname.  https is the
           default. The port number may be specified after a colon
           (":"), otherwise 19532 will be used by default.

       --system, --user
           Limit uploaded entries to entries from system services and
           the kernel, or to entries from services of current user. This
           has the same meaning as --system and --user options for
           journalctl(1). If neither is specified, all accessible
           entries are uploaded.

       -m, --merge
           Upload entries interleaved from all available journals,
           including other machines. This has the same meaning as
           --merge option for journalctl(1).

       -D, --directory=DIR
           Takes a directory path as argument. Upload entries from the
           specified journal directory DIR instead of the default
           runtime and system journal paths. This has the same meaning
           as --directory= option for journalctl(1).

       --file=GLOB
           Takes a file glob as an argument. Upload entries from the
           specified journal files matching GLOB instead of the default
           runtime and system journal paths. May be specified multiple
           times, in which case files will be suitably interleaved. This
           has the same meaning as --file= option for journalctl(1).

       --cursor=
           Upload entries from the location in the journal specified by
           the passed cursor. This has the same meaning as --cursor=
           option for journalctl(1).

       --after-cursor=
           Upload entries from the location in the journal after the
           location specified by the this cursor. This has the same
           meaning as --after-cursor= option for journalctl(1).

       --save-state[=PATH]
           Upload entries from the location in the journal after the
           location specified by the cursor saved in file at PATH
           (/var/lib/systemd/journal-upload/state by default). After an
           entry is successfully uploaded, update this file with the
           cursor of that entry.

       --follow[=BOOL]
           If set to yes, then systemd-journal-upload waits for input.

       --key=
           Takes a path to a SSL key file in PEM format, or -. If - is
           set, then client certificate authentication checking will be
           disabled. Defaults to /etc/ssl/private/journal-upload.pem.

       --cert=
           Takes a path to a SSL certificate file in PEM format, or -.
           If - is set, then client certificate authentication checking
           will be disabled. Defaults to
           /etc/ssl/certs/journal-upload.pem.

       --trust=
           Takes a path to a SSL CA certificate file in PEM format, or
           -/all. If -/all is set, then certificate checking will be
           disabled. Defaults to /etc/ssl/ca/trusted.pem.

       -h, --help
           Print a short help text and exit.

       --version
           Print a short version string and exit.

EXIT STATUS         top

       On success, 0 is returned; otherwise, a non-zero failure code is
       returned.

EXAMPLES         top

       Example 1. Setting up certificates for authentication

       Certificates signed by a trusted authority are used to verify
       that the server to which messages are uploaded is legitimate, and
       vice versa, that the client is trusted.

       A suitable set of certificates can be generated with openssl.
       Note, 2048 bits of key length is minimally recommended to use for
       security reasons:

           openssl req -newkey rsa:2048 -days 3650 -x509 -nodes \
                 -out ca.pem -keyout ca.key -subj '/CN=Certificate authority/'

           cat >ca.conf <<EOF
           [ ca ]
           default_ca = this

           [ this ]
           new_certs_dir = .
           certificate = ca.pem
           database = ./index
           private_key = ca.key
           serial = ./serial
           default_days = 3650
           default_md = default
           policy = policy_anything

           [ policy_anything ]
           countryName             = optional
           stateOrProvinceName     = optional
           localityName            = optional
           organizationName        = optional
           organizationalUnitName  = optional
           commonName              = supplied
           emailAddress            = optional
           EOF

           touch index
           echo 0001 >serial

           SERVER=server
           CLIENT=client

           openssl req -newkey rsa:2048 -nodes -out $SERVER.csr -keyout $SERVER.key -subj "/CN=$SERVER/"
           openssl ca -batch -config ca.conf -notext -in $SERVER.csr -out $SERVER.pem

           openssl req -newkey rsa:2048 -nodes -out $CLIENT.csr -keyout $CLIENT.key -subj "/CN=$CLIENT/"
           openssl ca -batch -config ca.conf -notext -in $CLIENT.csr -out $CLIENT.pem

       Generated files ca.pem, server.pem, and server.key should be
       installed on server, and ca.pem, client.pem, and client.key on
       the client. The location of those files can be specified using
       TrustedCertificateFile=, ServerCertificateFile=, and
       ServerKeyFile= in /etc/systemd/journal-remote.conf and
       /etc/systemd/journal-upload.conf, respectively. The default
       locations can be queried by using systemd-journal-remote --help
       and systemd-journal-upload --help.
