The Numix Project received some web love lately, mentioned in last Sunday's Linux Action Show web episode, and later on It's F.O.S.S and probably elsewhere, for their announcement to release their own Linux distribution. As a result, their website is now down, with the server returning 500:

[email protected]:~$ curl -I numixproject.org
HTTP/1.0 500 Internal Server Error

...and displaying the message "Bandwidth Limit Exceeded". I would have guessed that with everything-as-a-service and the whole Cloud #!, bandwidth consumtion would have already become irrelevant.

I mean, there's enough BW to feed our amplification attacks ( 400Gbps on CloudFlare, 350Gbps on OVH), but not enough to host our websites? Does that not call for a revision of the model?

The default-interface command removes configuration from an interface, and returns it to its defaults. Note that by default, interfaces are not shutdown.

The access-class command applies an existing access list on a line, such as VTY and CON lines. The equivalent command for interfaces is ip access-group.

Notes on the show vtp status command on Cisco devices.

The value of configuration last changed by shows the source of the most recent updates to the Vlan list.

show vlan lists the Vlans and the ports on which each is configured. Trunk ports don't show up in this list.

Vlans 1002, 1003, 1004 and 1005

In the output of the show vlan command, Vlans 1002, 1003, 1004 and 1005 are listed. Those exist by default to ensure interoperation and backwards compatibility of new devices with old and largely deprecated networks. For example, Vlans 1002 and 1004 were used on an old fiber optics type of network, whereas Vlan 1003 was used in token-ring networks. In the status column, those networks show up as either act/unsup or active/unsupported, since most new switches don't even have ports to use on those old types of networks any more.

As user zenoss (or whatever user your Zenoss application runs as), run zendmd, and:

Device = find('My Awesome Server')
Device.addDeviceGroup('My Wonderful Group')
commit()

This will make the device named My Awesome Server a member of the group named My Wonderful Group.
