The aim of this paper is to document the configuration of a Dedibox Ubuntu Server 4.10 LTS 64-bit. We will see how to secure a minimum the server (firewall, PortSentry, logwatch) and how to install Apache 2, PHP 5, MySQL 5, Postfix, MediaWiki, vsftpd, SVN + HTTPS, WebSVN and the SNMP daemon.

Installing Ubuntu on Dedibox is fully automated and requires no comment. I used the basic configuration proposed by the installation interface of Dedibox.

On one of my SQL Servers SNMP service continuously took nearly 20% of the CPU. Rather than restart the service I took the opportunity to restart the server completely and apply the latest up-to-day. The launch of Windows I got an error message indicating a crash snmp.exe. I first thought about a port problem but errors in the event viewer did not match:

Event Type: Error
Event Source: Service Control Manager
Event Category: None
Event ID: 7034
Date: 20/10/2009
Time: 6:52:40 p.m.
User: N / A
Computer: SERVERSQL
Description:
The SNMP Service service ended unexpectedly for the first time.

Finally I discovered that the problem was an extension of the SNMP service installed by my Adaptec RAID controller card. To disable this extension simply run Regedit, go to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ SNMP \ Parameters \ ExtensionAgents and delete value aussnmp containing the given SOFTWARE \ Adaptec \ RAIDController \ AAC \ CurrentVersion.

This data is apparently he recreated each time you restart the machine, it will therefore be to think of removing the value manually, or simply create a startup script to delete this value automatically.

On one of my Windows 2003 servers SNMP service could no longer start up properly: each attempt to start a rather uninformative message was displayed:

The SNMP Service service on Local Computer started and then stopped. Some services stop automatically if they have no work to do, for example, service alerts and performance logs.

In the event log, no error message but a series of informational message:

Event Type: Information
Event Source: Service Control Manager
Event Category: None
Event ID: 7035
Description: A start control was successfully sent to service SNMP Service.

Event Type: Information
Event Source: Service Control Manager
Event Category: None
Event ID: 7036
Description: The SNMP Service service entered the stopped state.

Event Type: Information
Event Source: SNMP
Event Category: None
Event ID: 1003
Description: The SNMP service stopped successfully.

Nothing very clear about the problem so ...

In my case I eventually discovered that the default port 161 used by the SNMP service was used by another service. To solve the problem just go to C: \ Windows \ system32 \ drivers \ etc and edit the file services. We must then modify the line:

snmp 161/udp #SNMP

by

snmp 165/udp #SNMP

for example.

Once this line has changed and saved the file, the SNMP service can start correctly.
