I am moving one of my site from windows to centOS hosting. The problem is that the new server is case sensitive for folders and file names. I had all my folders in capital letters previously and also all my links inside pages(www.domain.com/FOLDER/Page-Name.php).
I have nearly 1000 pages and most of them are indexed in google in this format
[url]
Now i have renamed all my folders, files and links inside the files to absolute lowercase.
Having made a switch from a Windows server to Linux to use Wordpress with better results, many external links are now pointing to invalid files because of case sensitivity.
Anyone know a formula e.g. (mod spelling & how to apply it) that can make it case insensitive?
If not, is there any harm in leaving two copies of each file e.g. cognitive-therapy and Cogntive-Therapy?
I just want an expert opinion if what I am doing should be considered to be secure (or if there is a more secure way to do what I am doing). I made our hotel's online reservation system and it stores the guests' credit card information.
The card is encrypted using AES (MCRYPT_RIJNDAEL_128) and the key that is used to encrypt/decrypt must be entered from the client side in order to log in. It is not stored on the server. So that my employees do not have to enter it every time they want to log in, it is stored in a cookie on their computer or entered manually if the cookie is deleted. When logged in, I have the key stored in a _SESSION variable in a subdirectory of that account's home directory and have the following attributes (for example):
Quote:
-rw------- 1 nobody nobody 0 Jul 9 16:48 sess_c1744d96fe87def6814db2c5936e1b1d
Does this seem like a secure enough way to store/encrypt/decrypt credit card data?
I am working towards launching a site that, among other things, will be a repository for sensitive data on war crimes. As these crimes are ongoing, and occur in a location where assassinations are endemic, I need to develop a comprehensive security strategy that takes into account all levels of the interface between end user / witness and the site / database itself.
I have considered, but am open to insight and advice on, the following:
1. Data security laws in given countries, in order to ensure the privacy and integrity, as much as possible and away from political / state interference, of data communications. Concerns include the interception of data in transfer and the security of stored data (the United States and the UK are almost certainly cancelled out in this regard. Canada appears significantly better, though Greece, it appears, has the greatest level of legislative protection).
2. Encryption as a technique to ensure the security of transfered and stored data. I am particularly interested in best practice advice on encryption.
3. Javascript as a means to establish a more secure interface between the end user (i.e., the browser interface) and the secured database into which sensitive data will be inputed. Has anyone used this, or other techniques of overcoming the inherent insecurity of the browser interface?
4. Various best practices concerning php, MySQL and Apache security. Any and all advice, or guidelines, welcome.
5. Considerations relative to dedicated hosting, and also colocation hosting as an option.
In general, my problem is to ensure that the identities of witnesses, so much as is technically conceivable, can be protected from extra-judicial interference or surveillance. Nothing about this site will be illegal in any way. The problem is that the witness testimony will be about the actions of a powerful state that has demonstrated its disrespect for law.
Ideally I'd find in these forums a few individuals with whom I could discuss these technical matters off-forum. At the same time, general responses would be values.
The site that I'm building is non-profit (indeed zero budget) and does not represent any political party. It's a people's initiative, against aggressive violence and in support of international law.
I have just migrated my server from a Linux CentOS VPS to a dedicated Windows Web Server 2008, everything seems to have gone quite well except xcache.
I have installed xCache v1.2.2 with the following configuration:
Quote:
[xcache-common]
extension = php_xcache.dll
[xcache.admin]
xcache.admin.auth = On
xcache.admin.user = "admin"
xcache.admin.pass = "b95e560e4a31ce20cd522f224932c080"
[xcache]
xcache.shm_scheme = "mmap"
xcache.size = 48M
xcache.count = 2
xcache.slots = 8K
xcache.ttl = 7200
xcache.gc_interval = 300
xcache.var_size = 128M
xcache.var_count = 1
xcache.var_slots = 8K
xcache.var_ttl = 7200
xcache.var_maxttl = 14400
xcache.var_gc_interval = 300
xcache.test = Off
xcache.readonly_protection = Off
xcache.mmap_path = "anonymous"
xcache.coredump_directory = "c:/xCache/tmp"
xcache.cacher = On
xcache.stat = On
xcache.optimizer = On
[xcache.coverager]
xcache.coverager = Off
xcache.coveragedump_directory = ""
If I open phpinfo I can see that xcache is loaded and can see the settings, I have also installed the xcache admin panel and I am able to access that without problem.
However if I enable xcache on in the PHP scripts (vbulletin) file I get multiples of the following errors:
Quote:
Warning: xcache_isset() [function.xcache-isset]: xcache.var_size is either 0 or too small to enable var data caching in [path]includesclass_datastore.php on line 557
Quote:
Warning: xcache_unset() [function.xcache-unset]: xcache.var_size is either 0 or too small to enable var data caching in [path]includesclass_datastore.php on line 596
Quote:
Warning: xcache_set() [function.xcache-set]: xcache.var_size is either 0 or too small to enable var data caching in [path]includesclass_datastore.php on line 597
Now unless I am being thick, var_size is currently set to 128M, it was originally 4M but as the error suggested "too small" I upped it a little with no affect.
The only thing I can think might be related to this is that I am using PHP 5.2.6 and I am using xCache 1.2.2 for PHP 5.2.5 as there is no 5.2.6 version

Is there any way to setup the server to ignore case-sensitivity? For example:
[url] is the same as
[url] or
[url]
Regardless of what is upper or lower case that it goes to the same directory.
Got a question about cases fans but know someone will have a laugh at me about this.
We have recently moved from 1u supermicro cases to matx cases to lower the general server cost. We realised that we wouldnt fill 2/3 of a rack if we used 1u (16 amps power would be hit) and it was just logical to use matx.
One worry is the heat factor so was looking at some powerful fans. The one place I know where to get them from is our dyanatron supplier but I am left very confused. You always see on fans they use 0.3amp/12v (for example) but how much does that work out to be at the final power usage? this goes for the same in watts. Are fans something you have to worry about in the long run or do they make a non exsiting dent into a racks amp usage?
I figured this would be the place to ask this question as the parts Im using are ex-server :-))..
Basically, I've purchased an old dual xeon board with matching xeons and I'm after a case. However the motherboard is EATX, and dosent seem to fit any of my ATX cases.
So, what case should I go for? Im trying to make it a cheap as possible.. Also I live in the UK.
I saw, this case. I figured for that price I cant go wrong. But will it fit an EATX?
I have had great difficulty in setting up OpenVPN, so I thought, when I finally do get it to work, I will write a HOWTO, so other can hopefully benefit…
This guide was done using a FC4 VPS, running on Xen, it will work on OpenVZ, all you need to do is ask your VPS provider to install “tun support”.
1.First of all get a few additional repos, If you already have your repos setup, skip this step
If you have Fedora 3, follow these steps,
[url]
If you have Fedora 4, follow these steps,
[url]
If you have Fedora 5, follow these steps,
[url]
If you have CentOS, follow the “additional third party CentOS repos”
[url]
Then issue these commands, each line is a new command, anything beginning with "#" are comments so dont try to execute those.
Code:
yum update
yum install openssl openssl-devel
# openssl and openssl-devel may be installed already… so don’t worry
2. Right, now you want to install OpenVPN, here are the commands,
Code:
yum install openvpn -y
#Now check that it works
service openvpn start
service openvpn stop
3. A few things to setup before you can make certificates, issue these commands,
Code:
find / -name "easy-rsa"
#you should get an output like this…
/usr/share/doc/openvpn-2.0.7/easy-rsa
#Now, make a copy of the easy-rsa directory, to /etc/openvpn/ ( make sure you #have put the right version number in i.e. mine was -2.0.7, change if needed)
cp -R /usr/share/doc/openvpn-2.0.7/easy-rsa /etc/openvpn/
cd /etc/openvpn/easy-rsa
chmod 777 *
mkdir /etc/openvpn/keys
4. You need to edit the vars file, located in /etc/openvpn/easy-rsa
You can use any editor you like, I used vi.
Change the line
Code:
export KEY_DIR=$D/keys
to
Code:
export KEY_DIR=/etc/openvpn/keys
Also at the bottom of this file you will see something similar to this,
Code:
export KEY_COUNTRY=US
export KEY_PROVINCE=CA
export KEY_CITY=SOMEWHERE
export KEY_ORG="My Org"
export KEY_EMAIL=me@mydomain.com
Change this to your own values.
5. Now its time to make the certificates, enter these commands
Code:
. ./vars
Code:
./clean-all
Code:
./build-ca
# just hit enter to the defaults apart from Common Name, this must be unique
# call it something like mydomain-ca
Code:
./build-key-server server
Code:
./build-key client1
# remember that common name must be unique e.g. use mydomain-client1
# and YES you want to sign the keys
Code:
./build-key client2
# do this step for as many clients as you need.
Code:
./build-dh
6. We are almost done now… right we need to create a few config files, you can download my template from here,
Code:
cd /etc/openvpn
Code:
wget www.designpc.co.uk/downloads/server.conf
# make sure you change a few things in the server.conf file, like DNS
# servers
Code:
touch server-tcp.log
~ this makes the log file..
Code:
touch ipp.txt
this makes the IP reservation list.
7. You need to make a few changes to OpenVPN itself. Go to..
Code:
cd /etc/init.d/
edit the openvpn file
#Uncomment this line (line 119)
Code:
echo 1 > /proc/sys/net/ipv4/ip_forward
Add these lines below it, changing 123.123.123.123 to your public IP address,
Code:
iptables -t nat -A POSTROUTING -s 192.168.2.3 -j SNAT --to 123.123.123.123
iptables -t nat -A POSTROUTING -s 192.168.2.4 -j SNAT --to 123.123.123.123
iptables -t nat -A POSTROUTING -s 192.168.2.5 -j SNAT --to 123.123.123.123
iptables -t nat -A POSTROUTING -s 192.168.2.6 -j SNAT --to 123.123.123.123
iptables -t nat -A POSTROUTING -s 192.168.2.7 -j SNAT --to 123.123.123.123
iptables -t nat -A POSTROUTING -s 192.168.2.8 -j SNAT --to 123.123.123.123
iptables -t nat -A POSTROUTING -s 192.168.2.9 -j SNAT --to 123.123.123.123
iptables -t nat -A POSTROUTING -s 192.168.2.10 -j SNAT --to 123.123.123.123
Now install iptables if you don’t have it already,
Code:
yum install iptables
#test it
service iptables start
service iptables stop
8. Now for the client config files. If your client is a Windows machine, make sure you have installed OpenVPN, use the gui version, downloadable from here;
[url]
You need to copy a few files from the server to your client machine, here is the list, located in /etc/openvpn/keys/
## WARNING ## Use a secure way of transferring these files off the server, something like WinSCP.
ca.crt
client1.csr
client1.key
client1.crt
Put these files in this directory C:Program FilesOpenVPNconfig
Now you need to make a client config, here is an example..
PHP Code:
clientdev tunproto tcp#Change my.publicdomain.com to your public domain or IP addressremote my.publicdomain.com 1194resolv-retry infinitenobindpersist-keypersist-tunca ca.crtcert client1.crtkey client1.keyns-cert-type server#DNS Options here, CHANGE THESE !!push "dhcp-option DNS 123.123.123.123"push "dhcp-option DNS 123.123.123.124"comp-lzoverb 3
Make sure you edit any of the lines with comments above them.
Call this file client1.opvn and put it in C:Program FilesOpenVPNconfig
Make sure the file extension is .opvn not .txt
To connect right click on OpenVPN in the taskbar >> Connect

I am wanting to put some fans in the metal cabinet, to bring in cool air, and let out warm air.
Does anyone know where you can find these sorts of fans?
Because the server inside the rack cabinet is closed, I can't use a fan with a Molex connector.
I haven't seen any case fans that use a usb connector, or just a normal power outlet connector.
does anyone know what desktop motherboard can it fit? prefer AMD desktop motherboard.
View 14 Replies View RelatedI'm reeling right now after my shared hosting has been down for more than 24 hours (and this isn't one of the super-cheapies, it's in the $20-$30/month range)
In the future I'd really like to be protected against this kind of outage... I know downtime is inevitable with any host, so I'm wondering if it's possible to have some kind of failover system. Maybe I could get a second account with a bargain basement host (<$10/month) and keep it relatively up to date with a mirror of my site. But I don't know how I could manage the DNS so it went to the second host in the even of a failure on the first....
Does this kind of redundancy exist as some product in the industry that I don't know about (is that what "colocation" is?)? Is it likely that my host has the ability/willingness to redirect my domain (302 or something) in times of trouble like this?
What is the worst case scenario that one can face if they switched all the sudden from mysql 4.1 to mysql 5 ? Are both similar to each other? Anyone have experiences to share maybe as to what happened when you switched from 4.1 to 5?

it would appear that Iron Mountain ( www.ironmountain.com ) has filed a trademark infringement suit against InterMountain Mortgage also known as Iron Mountain Hosting ( www.imountain.com ) regarding the use of "Iron Mountain" and various colors and service marks.
I don't think this will come as a surprise to many people given how similar these two names are, along with the fact that Iron Mountain have been involved in IT well before InterMountain Mortgage decided to take the plunge into hosting.
It's going to be an interesting trial by jury to say the least...
