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 ?
Ive just being doing some pings and tracerts on burst and it looks to me they have there new X0 fiber installed i still get around 20 hops and average 120ms ping any body found the new transit any quicker, im still deciding weather to go back to burst or not, the speeds are pretty much the same but it is too early to justify there stability
What do you think so far?

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?

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.

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.
Me and my friend are looking to place a few servers for a soho (3 servers or so). We need advise as the incoming connectivity will be fiber so we need to know what do we need to receive that fiber, we opted to go for the catalyst 2950 for the switch but if there's a good fiber switch,
Fiber will be 10mbps.
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?
who does fiber to the business parks in Troy, just off 75.

from Telia:
We regret to advise that we are currently experiencing a cable cut in
the United States. This outage is causing degradation in our IP
backbone, which may affect your service.
The fault has been brought to the attention of senior management, and we
are actively working to resolve the fault. Unfortunately we do not know
when the fault will be resolved.
We will update you as soon as we have further information, and apologise
for the inconvenience caused to you and your customers.
Here is the screen shot of the "mtr" running from two servers:
Server1: Fibre optic line from Tata Communication
Server2: DSL line from Tata Communications
Source servers are located in Kolkata India
Target server is located in Fremont California.
The fiber optic cable has:
A. Higher ping time and
B. Higher standard deviation
compared to the DSl line.
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,
I got this from my data center.

I know that the IMAP method has the sometimes useful feature of leaving the emails on the server when viewing using an email client like Outlook Express. However, in our case we were forced to use IMAP inorder to use AOL as our ISP and Outlook Express as our email client. Is there a way to have the emails removed from the server after downloading like a POP3 connection does?
The client fills up the mailboxes until the email stops working.

I've removed a website from my server, terminated the account, removed all files. But when you go to the domain name, you get the "Great Success ! Apache is working on your cPanel® and WHM™ Server" page. I dont want even that. I want nothing to come up.
I want it to appear as if the domain/server never existed and show up as a 404 or whatever (this was a forced remove). Is there any way to do this? is there something I didnt do? Or am I stuck since the domain is still pointed at my server.
I've tried to give the hint (move), but it hasnt worked, so I have a feeling I'm going to get questions about this new issue. It's a church related group (even thought theyve been warned this was coming), so its hard to be an AHole, but they need to go.
I just want it to come up as if it never existed on my server, if possible.
Sometimes if I tried to use rm to remove too many files I got this:
-bash: /bin/rm: Argument list too long
I think there was a workaround, like ls and then piping the result to rm, but I forget.
if a program is compiled and installed (configure -> make -> make install) with a --prefix pointing to an empty subfolder, then would removing it be just a simple delete the folder and it's contents action ($rm -fr subfolder/).
Ok so lets say I was to install php from source with a complile prefix flag set to /usr/local/php
Then all the binaries and configuration files are set within the directory (php/conf , php/bin). If I want to delete the php installation then I would just remove the /usr/local/php directory, No?
So I insert following code in my apache.htaccess file in order to remove www and php.This is my whole file
ErrorDocument 500 /500.phpErrorDocument 404 /404.php# force non-www domainRewriteCond %{HTTP_HOST} ^www.example.com$ [NC]RewriteRule (.*) http://example.com/$1 [R=301,L]#RewriteEngine onRewriteCond %{REQUEST_FILENAME} !-fRewriteCond %{REQUEST_FILENAME} !-dRewriteRule ^(.*)$ $1.php [QSA,L]
We are getting critical warning of disk space as a result of our exim logs, specifically exim_mainlog and exim_rejectlog.
What is the proper ssh command to delete or minimize these?
I am not that familiar with the correct commands. Both files are located /var/log/
I get this error in Plesk 8.6 when trying to delete a domain. I have tried various things from various forums, but they have failed:
Error: Unable to remove domains: Problems occured while removing domains: Delete database user failed: Object 'sys.queue_messages_210099789' does not exist or is not a valid object for this operation.
Earlier when I tried to remove it, it removed only physical hosting from the server (not the complete hosting account). When I try again to add physical hosting I get:
Error: DNSZone::Table:: select() failed: no such row in the table
Not sure if two errors are related. Can anyone help me out with this.
The one thing that currently annoys me is that when an account is terminated from one of our servers, the account is still left on the backup drive.
Is there any way to automatically remove the accounts files from the backup drive when terminating an account? Or do I have to continue to do it manually?
Using cPanel/WHM/CentOS on all servers.
I have a customer who has a problem, today when he opened Outlook Express, it downloaded his new mails and deleted them automatically and also other mails, then when he clicked the "Trash" directory, it was empty. He checked if no one set rules, and the rules dialog is empty. He says his antivirus is up-to-date.

On an apache server running cpanel.
Something weird happening here. I have tried every string possible...
There are a number of folders I want to remove off my server, tried the good old and simple...
rm -r /folder/
And then went and ended up with a string as long as my screen. No matter what I do, as it goes recursive in to the directory it asks me if I want to remove each file individually. No matter what string or action I take it insists on asking me as it goes to delete each file.
Could this be a configuration option in CentOS?
