How To Find The Fiber

May 26, 2007

Assuming that one was to get a local office in a town, how would someone find building or area that had a high availbility of fiber nearby, but was not a datacenter? Are their fiber maps for each big city? Does anyone have fiber maps for Houston, Texas? I would be interested in seeing these maps if possible.

Dark Fiber

Mar 27, 2008

Has anyone looked into getting dark fiber verse going direct with a transport provider? How much does dark fiber cost compared to say a Gig-E transport line? What kind of equipment is needed on each end of the fiber, and how much does this equipment cost? At what point does a provider look for dark fiber verse getting transport for a Lit provider?

Removing Fiber By Cutting It

Jun 23, 2009

We have a large amount of multimode fiber coiled up under our raised floor that needs to be removed. The end that remains intact is running to a SAN cabinet that is very densely populated and our vendor has suggested cutting the fiber to make it easier to remove without disturbing the remaining active fiber.

Does anyone have any experience cutting fiber in a data center environment ?

Are glass fragments or any other debris a concern ?

Does anyone have any information on a company called BROOKS FIBER COMMUNICATIONS - TEXAS? They are showing up in a couple CO's on the website.

I think they might have been bought out, possibly by Verizon/MCI. If anyone can share any information about this company that would be great. Nothing seems to show up in google.

Fiber Optic Cable Down - No Back-up

Jun 26, 2007

I put this in the co-location section since I am co-locating a server that I host a few Websites on. The server is located in the Pacfic Northwest at a hosting company out there. As you may know, this is a "more remote" area of the United States.

Today, the company lost all Internet access when a Fiber optic cable went down. Not only was my stufff down but the entire hosting company was down. In 10 years of doing Internet development, I have never seen this happen to any hosting company I have worked with no matter how good or bad they were. On top of that, it happened one time last year as well.

According to my co-location provider, the problem happened a long way up stream. SO far that the lines cannot be backed up. Is this true? Could a fiber optic cable fail at some point where it cannot be switched over to another line?

I don't know if I should I believe that or not. It would seem to me that it is a matter of money and they may not have a back-up system in place if the pipe goes down. Is it possible? Who's fault is it?

Corning Optical Fiber LEAF(R) Can Used In Indoors And Inter-floor

Dec 19, 2007

I just came across this listing for Corning Optical Fiber LEAF(R) on eBay [url]. I've never used optic fiber cables before and want to experiment with them for indoor and inter-floor(friend below) use. The listing says that the coating is CPC6, which is some kind of acrylic coating over the fiber.

My question is: Can the above cable be used without further sleeving or some other protection/covering over it? I read somewhere that the cable must be reinforced and covered with PVC jacket or something,

How-To: Find PHP Nobody Spammers!

Apr 9, 2004

Someone posted some code similar to below, I made modifications or two after trying to detect PHP "nobody" users, after dumping a few printenv I found PHP exports PWD when calling an external program such sendmail. Basically the PWD will show the user directory that is coming from, which is enough to detect who is sending SPAM even as nobody! It's not 100% secure in that they could wipe /var/log/formmail but I don't imagine any spam will notice the logger, they presume any cPanel server (or other CP for that matter) is the same.

mv /usr/sbin/sendmail /usr/sbin/sendmail2
pico /usr/bin/sendmail (paste the below code into it)
chmod +x /usr/bin/sendmail
echo > /var/log/formmail
chmod 777 /var/log/formail


# use strict;
use Env;
my $date = `date`;
chomp $date;
open (INFO, ">>/var/log/formmail.log") || die "Failed to open file ::$!";
my $uid = $>;
my @info = getpwuid($uid);
else {

print INFO "$date - $PWD - @info";

my $mailprog = '/usr/sbin/sendmail.real';
foreach (@ARGV) {
$arg="$arg" . " $_";

open (MAIL,"|$mailprog $arg") || die "cannot open $mailprog: $!";
while (<STDIN> ) {
print MAIL;
close (INFO);
close (MAIL);

Where To Find VPS On Litespeed

Feb 27, 2009

I tried searching for it on google but couldn't find any server company offering VPS using Litespeed instead of Apache. Yes, I know that Apache could be optimized, but would like to try a VPS or dedicated server with Litespeed, just for testing and learning to use and troubleshoot Litespeed. Does anybody here know of a supplier? I would need less than 10 gigs, 250+ Ram as well as cPanel.

Where Can I Find 10+ Tb Bandwidth

Sep 4, 2008

Here's my situation:

I run a site that does a lot of transfers AND uses a lot of CPU resources. I think I would like to get two different hosting plans to deal with these different patterns of usage, but where can I find a good host offering lots of bandwidth that is content to have it actually used? I've been with DreamHost for a while but they don't allow "data archiving" or whatever (and I have arguments against their claims but it's neither here nor there). So, really, where the heck can a guy find a good host offering plenty of space and bandwidth? Keep in mind I need pretty much no CPU power with such a plan; the web server can be stone cold stupid for all I care, as I can just get a VPS to run the CPU-intensive part of my site!
