Server/Hardware documenation

nospam@example.com (Jonas Genannt) — Sat, 28 Nov 2009 02:26:16 +0100

If you manage some servers you need to document, which server has got which ip address. I have written an small webapp for that stuff. You can create companies, networks and servers.

One server could have one operation system, one server type (like hardware or virtual) and the mac/ip addresses. For every operation system you can save an preseed configuration for debian installation.

Some screenshots of the app:

--------------

Update:

It works like the extlookup, but not with files - it does an database lookup.
--------------

Planed features:

- authentication
- connect virtual servers to hardware nodes

Updated CLI packages from 3Ware

nospam@example.com (Jonas Genannt) — Sat, 06 Jun 2009 16:10:39 +0200

MySQL user management

nospam@example.com (Jonas Genannt) — Fri, 01 May 2009 23:55:51 +0200

I have written an little script, that can create users at an MySQL database. It works like my Linux User management.

You can store the complete users configuration for one MySQL server in one file.

You can download it on jonas.genannt.name. Readme file is located here.

The script has got some limitations, you can only manage database and global privileges. The script can't handle table or column rights - but I will add this soon. I will also add the function to create and maintain databases.

This script and the Linux User management performs great with some system management software like cfengine or puppet.

Updated user_mgmt script - Passwd::Unix

nospam@example.com (Jonas Genannt) — Sat, 25 Apr 2009 00:53:34 +0200

I have uploaded an new version of my linux user management script. This new version fixes an Passwd:Unix bug - The library has got an problem with the umask. You can download it on jonas.genannt.name.

You may have noticed that the perl library Passwd::Unix is not available at debian lenny. I have created an ITP #525340 to upload Passwd::Unix into debian.

If my packages passes the NEW-Queue I will create an backport for lenny and upload it to backports.org.

RCS version control number in Cfengine

nospam@example.com (Jonas Genannt) — Tue, 03 Feb 2009 19:31:03 +0100

If you are using Cfengine and use RCS to store your cfagent.conf file, you could use your RCS version control number inside Cfengine.

Example on editfiles:

{ /etc/screenrc
Append "#CFEngine: $(RCSRev)"
Append "vbell off"
}

The $(RCSRev) will hold the current RCS version number. So you will distribute the version of cfagent.conf in your files.

I had some problems to get this working, therefore an little guide for other guys around the net:

Precondition: cfagent.conf is controlled via SVN

Add the following code to your control selection:

RCSRev = ( ExecShellResult("/bin/echo \"$Id: $\" | /usr/bin/cut -f3 -d \" \" " ) )

Save your cfagent.conf and run svn propset svn:keywords "Id" cfagent.conf && svn -m "RCS" commit cfagent.conf.

This command tells subversion that svn should replace $Id: $ with the current RCS version and commit it.

If you open your cfagent.conf again, you will notice that the line above changed to:

RCSRev = ( ExecShellResult("/bin/echo \"$Id: cfagent.conf 20 2009-02-03 18:21:33Z jonas $\" | /usr/bin/cut -f3 -d \" \" " ) )

That's all - you can now use $(RCSRev) inside your cfagent.conf.

webalizer IPv6 addresses

nospam@example.com (Jonas Genannt) — Sun, 21 Sep 2008 14:27:50 +0200

If you are using IPv6, you know that webalizer truncates IPv6 addresses, this is very bad for the statistics.

The IPv6 patch is available at #452259.

I have included the patch and rebuild the package for etch. You can download the debian package at jonas.genannt.name.

Debian Repository for 3Ware packages

nospam@example.com (Jonas Genannt) — Sat, 13 Sep 2008 13:48:46 +0200

I have set up an Debian Repository for my 3Ware packages. You can now install your 3dm2 and cli packages via apt.

Add the following line to your sources.list:

deb http://jonas.genannt.name/debian etch restricted

For testing aka Lenny you have to replace etch with lenny.

This repository is signed with my GPG key (0xB616FFFA), you should add my key in your apt-keyring:

wget -O - http://jonas.genannt.name/debian/jonas_genannt.pub | apt-key add -

vlans + 3DM2

nospam@example.com (Jonas Genannt) — Mon, 08 Oct 2007 22:54:06 +0200

This morning, I had to install my 3dm2 package on an server with vlans on the local ethernet device.

I installed the packages as always, but I was not able to start 3dm2. The software failed with

(0x0C:0x0005): Failed to start listening socket

After some debuging, I have changed RemoteAccess parameter to 0. After this modification in the configuration file, I was able to start 3dm2 on the machine.

So I think 3dm2 is not able to handle ethernet devices with vlans enabled...
