Environment

Novell Open Enterprise Server 2018 SP2

Novell Open Enterprise Server 2018 SP1

Situation

novell-named service logs messages to /var/opt/novell/log/named/named.run and and also to syslog. Currently there is no way to disable logging messages of novell-named service to syslog.

Resolution

The shell script given here modifies the rsyslog configuration and stops the messages from novell-named service from getting logged into /var/log/messages. This script provides a way to disable messages to syslog. Messages will continue to be logged into /var/opt/novell/log/named/named.run

Examples

./control_named_system_logs.sh -d: To disable capturing of novell-named logs in /var/log/messages ./control_named_system_logs.sh -e: To enable capturing of novell-named logs in /var/log/messages ./control_named_system_logs.sh -h: Help

# This script updates the rsyslog configuration in a way that

# Whether for service novell-named, the logs are captured under /var/log/messages

# New configuration file, which gets created in process

FILE="/etc/rsyslog.d/dns-query-log.conf"
