Is bandwidth still relevant for web hosting?
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?

show vlan (Cisco)
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
active/unsupported, since most new switches don't even
have ports to use on those old types of networks any more.
Zenoss: Add a device to a Group with ZenDMD
zenoss (or whatever user your Zenoss application runs as), run
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.
