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.
