Burstable Lines
Mar 20, 2008if a provider provides me a 1Mbps AIMS dedicated line for my dedicated server, is it possible for him to make it burstable to 1.5Mbps? i thought when i get a dedicated line i would be able to get max 1Mbps only? How is it possible that it can be burstable? Does that mean its not dedicated, instead shared?

Sep 26, 2006I currently have a dialup isp. We use a couple of wholesale dialup service providers to provide service to our users across the nation. I would like to provide my own dialup services across the nation if the cost is justible.
Here is what I want to do:
1. Buy a remote access server (RAS) with hundreds of modems in it. The RAS will have multiple T1/PRI/T3 interface cards in it depending on which one I get.
2.Place the RAS in a Houston, TX datacenter.
3. Get voice services from a carrier that can deliever multiple T1/PRI lines (or a T3). I would want a local DID or phone number in hundredes of locations across the nation. When a number is called, it would be rerouted back to the Houston, TX PRI/T1/T3 connections WITHOUT ANY LONG DISTANCE CHARGES.
Is this possible without paying an arm and a leg for it? Can anyone give me any recommendations besides stay with a wholesale dialup provider.

May 12, 2013My linux host requires a few lines of codes in my .htaccess file to properly run my site.
However, these few lines of codes are not supported by my local Wamp on Win7.

So that I don't have to manually change the .htaccess file before upload/downloading the site between the two systems?

Power Supplies: Do Redundant Supplies Use More Power Than A Single Supply
Jul 27, 2009do dual power supplies use more power than a single supply?
E.g. Say I have a server than uses two amps, powered by a single power supply. Now if I switch to a dual supply (and say each supply has the same efficiency rating as the single), does my server use more power? How much more?
My simple view of this is that it probably does, but maybe not much. The second power supply consumes some power itself, but since its not under load, it doesn't consume much. Therefore, my server with redundant supplies might use 2.1A or 2.2A.

Aug 19, 2008I've supposedly set APF firewall to start at boot time, by doing something like:
chkconfig --levels 2345 apf on
However i have my reservations to weather it is actually starting, its set to block port 80, after boot if i try and access it, the connection will get refused straight away, however if i go and manually start APF then try and access again, it will take a while, like its ignoring the connection attempt (which is good).
How could I check if APF is actually running?

New Server Won't Boot
Nov 10, 2007I'm trying to put together a new 1U rackmount server that I'm intending to colocate (my first server of my own). Here are the details:
11-152-087 CHASSIS SUPERMICRO|CSE-512L-260B R
13-182-120 SERVER_MB SUPERMICRO|MBD-PDSML-LN2+
22-144-417 HD 250G|WD 7K 8M SATA2 WD2500JS
19-115-029 CPU INTEL|C2D E6750 2.66G 65N 4M R
20-134-337 MEM 1Gx2|KST KVR667D2E5K2/2G R
The stock CPU fan is obviously too big to sit in a 1U rackmount chassis, but I've got the top off and was just trying to boot up with the OEM fan to make certain everything worked (forgot to order a low-profile fan and heatsink--they're on the way).
Well, I put everything together, and it won't boot. Upon power up, there is nothing sent to the VGA port, and after a second or two, there is a hi-low alarm sound that does not stop that seems to imply the system is overheating (the MB and chassis manuals don't mention this alarm anywhere, but the read "temperature" light on the front is red). The CPU fan runs as well as the case fan, and even if I hold a huge high-velocity home fan over it, it still won't send any signal to the VGA monitor or POST.
I've checked that the power connections are good, the fans are seated properly, the memory contact is good, etc., and all I get is this hi-low chime every time I try to boot up. I think it's either a bad MB or CPU, since I can't imagine that the CPU is overheating with the heat sink and CPU fan.
Perhaps I've screwed something up, but the next issue I have is trying to figure out what could be causing the problem so I know what to return or replace. Is it the CPU? MB? RAM? Power unit? How can I test any of these without buying another set and possibly frying those?
I figured maybe some of you might have some ideas. I've built several computers over the years, but this one has me completely stymied.

Network Boot Across Many VLANs
Dec 4, 2006I'm not sure exactly how to phrase the question. But, I'm researching how to PXE boot a server without having a DHCP/PXE server in each vlan.
Scenario: Datacenter with dozens of servers. 1 VLAN per server. Cisco switches and routers. Each server has a serial console available for remote management (OS and BIOS are configured for serial console). If an admin wants to re-install OS, they should be able to reboot the server and tell the BIOS to initiate a PXE boot request. A central install server is available to provide the DHCP and PXE boot images.
Has anyone tried this? I have been reading about the 'ip helper-address' for Cisco to relay DHCP requests. Interested in hearing about real-world setups. Or is there a better way to accomplish remote OS installs?

Way To Clean Up /boot Partition
Mar 14, 2008I've got Centos 4 and I'm wondering what's the best way to cleanup my /boot partition?
Tried to do a yum update tonight and it included kernel, amongst other updates that belonged there so it stopped. I've googled around for commands to run and whatnot, but no go... or I just can't find it... if I had to clean it up I have an idea already about what to do, but I want to ask for advice first to see if there's an easier way.
so, how do people here clean up that partition?
