NAME¶

systemd-journal-upload.service, systemd-journal-upload - Send journal messages over the network

SYNOPSIS¶

systemd-journal-upload.service

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

DESCRIPTION¶

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 transfers the raw content of journal file and uses HTTP as a transport protocol.

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¶

-u, --url=[https://]URL[:PORT], --url=[http://]URL[:PORT]

--system, --user

-m, --merge

-D, --directory=DIR

--file=GLOB

--cursor=

--after-cursor=

--save-state[=PATH]

--follow[=BOOL]

--key=

--cert=

--trust=

-h, --help

EXIT STATUS¶

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

EXAMPLES¶

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.
