Howto control Tomcat using wget

I just had to restart a webapp in Tomcat without stopping a second app running in the same tomcat instance.

Usually this can be done easily via the Tomcat Manager, but in this case I was not able to access the Manager due to firewall rules. Though I was able to access the server using ssh, but there was no curl installed.

Luckily wget did the trick too!

Howto: Log firewall from OpenWrt to a remote rsyslog

This is how I got remote logging from my OpenWrt router to the syslog daemon on the server box.

On the server side, I enabled remote logging over UDP (refer to the rsyslog or syslog-ng documentation).

On the OpenWRT box following steps are needed

Enable remote syslog logging

Edit /etc/config/system and enable remote logging by adding:

option 'log_ip' ''

Now reboot the router and see if it logs correctly.

Solaris and DNS

Just that I'll never have to google this one up again....

To get Solaris to make use of your ususal DNS

cp /etc/nsswitch.conf /etc/nsswitch.conf.orig
cp /etc/nsswitch.dns /etc/nsswitch.conf
echo "nameserver xxx.yyy.zzz.bla" >> /etc/resolv.conf
svcadm restart nscd

There we go.
