SNMP on grml/debian

I've been adding some additional servers into my Zenoss system. As most of my Linux boxes are running CentOS Linux, adding them in is no problem.

But I have one grml system. Why different? I had downloaded an appliance from the vmware community site. I needed a bugzilla system - there was one ready built - it seemed like a good idea at the time!

So,...
I had checked that snmp was installed on the system.
I had edited the /etc/snmp/snmpd.conf file to include the settings I wanted.
I had started the snmpd service.

But I couldn't perform an snmpwalk from my zenoss server and couldn't add it as a device into Zenoss!

Some digging with netstat revealed that port 161 was only listening for the localhost/127.0.0.1! Which was confusing because I wasn't configuring it to be like that.

Where was it picking that up from?

A quick google, quickly found these two sites, HowToForge & DebianWiki with essentially the same information.

There are some default setting in /etc/default/snmpd including the value of the environment variable SNMPDOPTS.
Out of the box, it is set to
SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1'
which I chenged to
SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid'

I restarted the snmpd service and checked the result from netstat -an

Huzzah!

I checked the snmpwalk and saw screeds of stuff fly up my console. And lastly, I successfully added the box into zenoss.

And that's that!

Modifying the Keyboard on Debian Linux

So I've downloaded the SyslogAppliance v0.0.4 to act as a Syslog Server in the company's DMZ. I ran the appliance initially in VM Player and then used the Enterprise Converter to import the appliance into a Virtual Machine on our VMwareESX server.

By default, the appliance is set up for a US audience with US keyboards. That's not a problem. After 20+ years in IT, you expect that and I know my way around a US keyboard, especially as I work for an American concern. Anyway, the ReadMe.txt file that's packaged with the appliance provides you with information on how to configure a UK keyboard.
...
VMWare Settings
- 256 MB memory (you should increase this for large log volumes)
- 64GB virtual disk
- listening on port 514/UDP and port 514/tcp
- US keyboard, to install a different local, do
$ apt-get install console-setup
$ dpkg-reconfigure console-setup
...

Obviously, despite both being Linux, it uses a different mechanism from that used by rPath in an earlier post on this blog. But two command lines isn't too painful.

Oh. That's unfortunate! Maybe this won't be so easy.

15 minutes of googling around apt-get and reading the more obvious looking results.

Despite the quantity of output, it didn't take more than 10 to 20 seconds.

Now to configure the software.

appliance:/etc# dpkg-reconfigure console-setup
























And that's that!
