A.3. Logging to a Remote System During the Installation
By default, the installation process sends log messages to the
console as they are generated. You may specify that these messages
go to a remote system that runs a
syslog service.
To configure remote logging, add the syslog
option. Specify the IP address of the logging system, and the UDP
port number of the log service on that system. By default, syslog
services that accept remote messages listen on UDP port 514.
For example, to connect to a syslog service on the system
192.168.1.20
, enter
the following at the
boot:
prompt:
linux syslog=
192.168.1.20:514
A.3.1. Configuring a Log Server
Fedora uses syslogd
to provide a syslog
service. The default configuration of syslogd
rejects messages from remote systems.
|
Only Enable Remote Syslog Access on Secured Networks |
The syslogd service includes no security
measures. Crackers may slow or crash systems that permit
access to the logging service, by sending large quantities of
false log messages. In addition, hostile users may intercept
or falsify messages sent to the logging service over the
network.
|
To configure a Fedora system to accept log messages from other
systems on the network, edit the file
/etc/sysconfig/syslog
. You must use
root
privileges to
edit the file /etc/sysconfig/syslog
. Add
the option -r
to the
SYSLOGD_OPTIONS
:
SYSLOGD_OPTIONS="-m 0
-r
"
Restart the syslogd
service to apply the
change:
su -c '/sbin/service syslog restart'
Enter the root
password when prompted.
