This is yet another update to my list of SysAdmin inventory and accounting tools.

As an update to my old post on a few SysAdmin tools, I just did some searching for SysAdmin inventory tools and accounting and found the following I'd like to check our some day: http://www.spiceworks.com/welcome/ http://www.ocsinventory-ng.org/en/ http://www.opsi.org/en http://www.fusioninventory.org/overview/ http://www.glpi-project.org/?lang=en http://www.manageengine.com/ http://www.kaseya.com/ http://www.racktables.org

It's unbelievable that QNAP still doesn't support multiple VLANs on a single bond0 interface via GUI when they now just released the QTS v4.1.0 NAS Operation System for QNAP. The underlying Linux OS (QTS) does support it, and there should at least not be any problems with Intel chipsets. Some are reporting problems with Marvell.. but I haven't tried. I wanted to use the QNAP as a iSCSI storage for my LAB using a second interface while having full redundancy and get max bandwith (2x1GbE) for my ESXi hosts, and I didn't want that interface routed. At the same time I of course need the possibility to manage the QNAP system via the main interface, which is routed. This CLI "hack" will at configure the QNAP for a second VLAN interface that will be persistent during reboots. It's not been verified that it works after an upgrade of the firmware, but I presumed it will. To get this to work I presume you already have the following working: Network onfigured...

If you keep getting eth1 instead of eth0 as your main ethernet interface on a (newer) linux template/clone in a virtualized environment it's most likely because your udev rules is in affect and creates a new eth1 since eth0 is already defined and bound to the clone/template source's MAC address. This can be fixed in a couple of ways (in your template/clone source image): 1) You can delete the ' SUBSYSTEM ' line in your  /etc/udev/rules.d/70-persistent-net.rules : Edit the rules files   vi /etc/udev/rules.d/70-persistent-net.rules Delete the SUBSYSTEM line(s), feel free to also delete the comment about PCI device just above: # This file was automatically generated by the /lib/udev/write_net_rules # program, run by the persistent-net-generator.rules rules file. # # You can modify it, as long as you keep each rule on a single # line, and change only the value of the NAME= key. # PCI device 0x8086:0x100e (e1000) SUBSYSTEM=="net", ACTION==...
