Air-stop Foam Cubes For Cut Tiles
Nov 2, 2007
There used to be a product called the "sub-zero pillow" that was basically a foam cube, which you could stick into square cut-outs in datacenter floor tile, to block airflow. I've found something similar, called the Absolute +4 Air Stop:

Does anyone have pointers to similar products? Cost is a consideration for me.

We are a mapping software developer that does a lot of web hosting ourselves. Our new web applications have map caches which consost of a series of "tiles" which are 512 x 512 pixel images ranging from 10 -100k in size. I am trying to find options that will be able to host about 500gb worth of these tiles and serve them very quickly. I am not sure what our options are, and whether using something liking amazon s3, or cachefly is worth the extra cost for what we are trying to do. It looks like the minimum number of tiles requested at a time would average about 1000/minute for peak usage. Would one of the cheap hosts, like dreamhost provide better performance than hosting this ourselves? I don't know if we would run into bandwidth issues with our current environment.

I was wondering if anyone has any methods to stop spammers? Currently i am keeping watch on the mail queue and making sure nothing unsual. I have in WHM configuration setup to not allow more 200 mail messages per account per hour but for some reason it will hit thousands. WHMCS does seem to suspend them automatically or maybe its because of WHM BUT only when its too late.
Any thoughts or suggestions?

how to stop gunzip -c?
By mistake instead of using gunzip file name on my friend's vps, I had used gunzip -c filename
and its taking hell a lot of time to unzip it, I have no clue on how to stop this and I am scared if I close ssh client, it might be still adding load to the server ..
I am unzipping an 4.5mb file, which on un-compression must be around 14.5mb ..
for the past 10 mins its still unzipping and not sure how long it will go on.. unless I stop it..

a site i manage for a client is being hacked every couple of days, its not the actual site but the hosts server thats getting attacked, all sites on that server, well actually all thier servers.
They have made no attempt to sort this problem, i report it they look at the site and say "site loads fine for us" which it does.
All index files are having a base64 encode line written after the <body> tag, this adds hundreds of spam links which are hidden with display:none; they also add .html to application types in htaccess for php to run in these files too.
Problem is, i am moving the site to another host but cannot change the nameservers to the new host's untill the client returns from a holiday, so i must keep the site up on the insecure host for now.
I am removing the spam code almost daily, is there anyway i can stop this attack happening for the time being, the host does nothing.

Is there a way to stop hotlinking? I have a client who has a blog. They have post pics of tattoos. Now there are at least 50 tattoo forums, blogs and other sites hotling to the pics. Now his bandwidth usage has skyrocketed. So enable hotlink protection in his cPanel. Just did a redirect to my main hosting site with a nice please stop hotlink image. Now I see all this in my logs. So I then made a 150 x 9000 clear BG gf with the text at the top please stop hotlinking.
My questions is there any way to stop it. If not should I just make a 1x1 clear gif to redirect to? Also is there a way to not have this traffic show in my log files?

I want to stop emailing myself
I have received quite a few emails from senders claiming to be the recipients [in this case one of my email accounts]. I did not send these emails. This is happening with almost every email account I have setup on one of my domains.
I know this is probably an easy fix-- I am simply unsure of what it is.
I noted that someone else recently posted a similar question-- with only one response. I wanted to see if another post my garner another response.

I can confirm that the person who is doing this IS NOT using the 'nobody' user because I am keeping a spam_log for that.
How else is a user able to use our server for spam? Please help as I would like to get this sorted ASAP.

I have my own server which I use for my own websites.
I use the following features of WHM -
Creating accounts
Deleting accounts
Creating "packages" for my accounts
Restarting services
...and possibly one or two other items once or twice a year.
I use the following features in Cpanel -
Checking statistics
Adding e-mail accounts
...and possibly one or two other items once or twice a year.
I'd like to break the (small) WHM/Cpanel habit I have and do all of the above via the command line.
Is this a big task?
Where should I start?

One of the servers have 1 account on, but seems like its extremely attacked. I cannot SSH and many packet loss. so I asked softlayer and they access it and said its a SYN Flood as from the /var/log/messages (I cannot see it as the server is not accessable) they put the main public ip under Cisco guard but still didn't help. when I asked for any solution, unfortunaly I were told there isn't and have to wait the attackers to stop as it comes from MANY addresses that iptables even won't help.
Isn't there any solution (software-hardware) to stop that ?

This is something that has been playing on my mind for a while now and this may be the place to create a plan.
How many of you are recieving emails advertising pills, viagra etc.
And how many are recieving them from domains totally unrelated to the above, sometimes from even your own address??
Has anyone got any thoughts or ideas about how we can put a stop to this?

there is a customer who transferred their site over to our servers and has run into some kind of encoding issue.
They have file on their website named:
EXCL%204810_00%20BeefSkewers.jpg
You can see that the "%20" characters are actually part of the file name on the server.
So the problem is that when they try to call the image in a URL:
[url]
It gives a 404 not found error.
We use apache 2.2.x on our servers, and my admins are stuck on how to fix this.
(Besides renaming the files. The problem is that this issue appears to also effect other text in their database that uses various symbols, such as the ", ', and the degree (for temperature) sign...)

I was using a server from dedicatedbox until last month. And I didn't want suffer anymore from their terrible service (IP taken away/provided less memory then ordered/down time/rarely answered support tickets/refused to fix problem after phone call), so I terminated my server last month. So my server was indeed shutdown as requested.
But after terminating the server, they still keeps sending bills and charing me. I have my credit card charged back the first bill. But seems that they are going to charge me another time this month. I tried to call them, but the phone call wasn't answered.
how could I stop them from making trouble?

I have CSF installed and working, but when I check the server secuirty it has saslauthd (see below for full message), now is it safe to stop and won't break anything ?
I am running on a VPS with cPanel/WHM
Check server startup for saslauthd
WARNING
On most servers saslauthd isn't needed and should be stopped and disabled from starting, as it could pose a security threat. This service is currently enabled in init and can be disabled using:
service saslauthd stop
chkconfig saslauthd off

I'm on a Cpanel/WHM (latest release version) VPS with centos 4.6.
Over the last month or so, I have been routinely having /tmp directory hacks of various types (3-6 a week), often resulting in the processor spiking to 100% and load popping up.
What do I need to do to prevent /tmp directory attacks, but still mantain the functionality that the /tmp directory is intended for?

For 2 weeks I am under DDoS.
The type of DDoS is the one that comes from DC clients.
I have managed to mitigate the attack and to get everything working ok.
I do not like the solution I came up with for many reasons and I found that squid can be good on stopping bad requests like the one that DC clients send when the attack occurs.
I am kinda new to squid and I do not know all the settings.
I have configured It and everything works great when there is no DDoS.
But when the attacks starts , nothing works. Squid does not log anything in access_log and also, there is no load, just a lot of connections to squid.
Is there a limit for max concurrent connections in squid ?
Or the ideea of using squid as a reverse proxy without caching, just to stop bad requests is a bad one ? (I do not need snort-inline, I have some issues with it).

working as domain admin in a web company.
Well i generally mail newsletter and offers to my subscribers in different domain using 6 IPs in my domain but due to slowness and huge spam receiving from the sender domains i m now deciding to increase my IP to 20. In which i will be using 10 each IPs distributed in two domains.
Will it be good by doing this ? Will it stop the rate of spam? Will the domains where i m sending the mails block me ?
