How to Stop syslog Messages to Write Console on Solaris

you can edit the entries in the /etc/syslog.conf to direct to another file eg /var/log/syslog instead of /dev/console. After that, issue kill -HUP to “reinitialize” the config

or if you want to stop syslog process/daemon in Solaris 10, (not /etc/init.d/syslog stop)

it should be

svcadm disable svc:/system/system-log:default

svcadm disable svc:/system/system-log:default turned syslog off you need to also run svcadm enable svc:/system/system-log:default to turn it back on, after you made the right changes to /etc/syslog.conf so it does what you want. You can probably just comment out the line as it is also logged to file in /var/adm/messages.log

Turning syslog off is not a good idea.

That’s is How to Stop syslog Messages to Write Console on Solaris.
