<title>Description</title>
<para><command>systemd-journal-upload</command> will upload journal entries to the URL specified
with <option>--url=</option>. This program reads journal entries from one or more journal files,
similarly to
<citerefentry><refentrytitle>journalctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>.
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.</para>
<para><command>systemd-journal-upload</command> transfers the raw content of journal file and
uses HTTP as a transport protocol.</para>
<para><filename>systemd-journal-upload.service</filename> is a system service that uses
<command>systemd-journal-upload</command> to upload journal entries to a server. It uses the
configuration in
<citerefentry><refentrytitle>journal-upload.conf</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
At least the <varname>URL=</varname> option must be specified.</para>

<title>Setting up certificates for authentication</title>
<para>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.</para>
<para>A suitable set of certificates can be generated with
<command>openssl</command>. Note, 2048 bits of key length
is minimally recommended to use for security reasons:</para>
<programlisting>openssl req -newkey rsa:2048 -days 3650 -x509 -nodes \

</programlisting>
<para>Generated files <filename>ca.pem</filename>,
<filename>server.pem</filename>, and
<filename>server.key</filename> should be installed on server,
and <filename>ca.pem</filename>,
<filename>client.pem</filename>, and
<filename>client.key</filename> on the client. The location of
those files can be specified using
<varname>TrustedCertificateFile=</varname>,

and <varname>ServerKeyFile=</varname> in
<filename>/etc/systemd/journal-remote.conf</filename> and
