My server was recently hacked and I'm looking ways to secure it in the future. I use the server to host my own websites.
It was hacked to be a spam server. I traced the new files the hackers added to my "upload" directory, which is where my site members upload pics. I had set the directory to chmod 777. Could someone hack that directory solely from it being its rights being 777?
The site was custom developed in PHP, and looking through it myself, I couldn't find any security issues. But then again, I may not know what exactly to look up.
I would appreciate any general tips to protecting a server, as well as general tactics hackers use to hack a server and PHP site.

What scripts/tools or configurations on a CPanel/WHM (Centos) server can you make to prevent spam from getting sent out by "clients" you may be hosting or just spam in general.
As, in the hosting industry, you are always going to have a client or two successfully send out spam, as some spam may not look like spam, but if you do not follow all the guildlines, I know regular newsletters can be consider spam.

While I am used to reselling and domain registration stuff, I am totally new to DNS stuff..I tried many searches and readings without hope.
that's why I need your help.
We have a problem that makes both incoming and outgoing emails from our website's email server not going or received, without any failure message or error message on both sides: the sender and receiver.
We talked to our webhosting company- they do not own, but host on a dedicated provided by Iweb in Canada - and they told us a quick solution for this:
To buy a private IP address, therefore our websites with them will not get blocked as spammy IP, setting us away from the dozens of sites they have on the same server IP (as domaintools reverse IP reported: xx other sites hosted on this server).
The company I work for agreed on this solution immediately as we are loosing customers for this problem.
They charged us 8$ a month for this "private ip".
We had the same problem for another day after their solution, when I checked domaintools, I found our websites are still on the same IP of the company. I called them, and the Admin there told me: it's a hidden CNAME setting that is not shown to public because it's "private" and the delay happenned because we had to contact Hotmail staff and wait for their reply to include it in their safe list, but others as Gmail and Yahoo do not require contacting them and will go through automatically."
My question is:
- What is Private IP/ Private DNS?
- Why and how it is used to prevent false blocking/bouncing?
- Does that mean they had to sell it to every domain, while their IP is not on blacklists (I checked it).
- Is Private IP just an internal setting or it has to be bought from a large ISP
like regular/public IPs? and if just some settings, is this price fair? we pay 120$ annually for hosting one site with them.
- They told us they put our other two sites on theis same new private IP. How can this be possible?
- I cannot understand: Hotmail can prevent our emails from reaching inboxes, but can it also prevent its users emails from reaching us?? Is this issue a Private-IP related??
- What do you think the real problem is, and what advice(s) should I follow to have our emails going and coming smoothly in the future?
Note: We don't send unsolicited emails ever. We only have a 1500-member mailinglist that we send a newsletter to, once every few months.
Our daily email traffic is about 10 to 20 messages in and out.

I've been with LayeredTech and my yearly renewal is up. Their pricing went up significantly, so I'm shopping at SoftLayer amongst others. My site gets roughly 700k unique visitors and 1.8 million pageviews. These numbers will likely go up. I run vBulletin and Joomla dbs. I have two identical servers (one has cPanel). They are configured:
Dual Quad Core 5310 Intel XEON's 1.60 GHz-- Dual 73GB SCSI drives - 4GB RAM -- 8GB Cache.
The webserver uses Litespeed as an apache replacement.
Q: They are offering upgrades to either Xeon 5320 or 5335. Does anyone have a recommendation on either?
Q: I've heard that database servers don't necessarily need as much spec wise as webservers. Should I upgrade my webserver? Downgrade the mySQL server?
Unfortunately, I need to make this move today to get the pricing and put the wheels in motion, so I don't get billed by Layered Tech for 1 year of service.

I was just wondering is it possible to move a directory to another server through SSH?
I bought a website a few weeks ago and I have all the files on the server except 30gb of content, now I've tried to put the folder into a tar archive but every time I try it brings up this error:
So I need a way to drag that folder from the old server to my new server through SSH because it will take me ages downloading and uploading all the content.

I'm a programmer at a company, and since I'm the only technical inclined person I have been given the responsibility of a "server" move - even though I'm a bit on the deep end here.
At the moment we have a shared hosting solution were we have our email and an ASP.NET application. We need better performance and thus we are moving to a dedicated server at ServerBeach.
I need to install our app at the dedicated server (that's the easy part), and then I need to setup Exchange Server (hard part) and then also obviously move the domain so it points at the new domain.
I have never ever installed Exchange on a server and I've heard it's a real PITA.
My checklist is this:
Install db
Install app
Make a redirect from the old server place to the new server
Set up Exchange Server 2007
Point the domain to the new place.
I'm the process of reading a 172-page long guide from MS on how to installing Exchange 2007, but I'd be interested in hearing any hints and tips on this.

I got an idea that using r1soft CDP to move server, since it provides restoring data to a different server. But I never used it, not sure if it is doable.
Any one did this before? any requirements (software/hardware) for new server that will be moved in?

I have two dedicated server, and I want move a domain from one to the other.
Although I changed the name server 3 or 4 weeks ago, still some mails hit to old server (this can be checked after POP3 login with IP address of old server).
Most of mail reach to a new server but still some to old.
if this would be propagation problem with ISP or something wrong with DNS set up on the server?

Only just started designing sites for clients as an add-on to promotional work, all of which are on shared servers that clients have organised for themselves, so all we do is Ftp content to the servers when required. However, we now have a client who wants to use video on their site, which, I understand, requires a dedicated server if we do not want to use a video hosting service (is there a video hosting service that does not demand credit when the video is run?).
The move to a dedicated server is a step into the unknown for us. If we have a dedicated server, does this give us the potential to host other client sites on it? What should we be looking for in terms of bandwidth, transfer rates, etc? Can anyone recommend good video streaming software? What are the potential pitfalls?

to move 14 servers from one facility in the Westin Building to another. IPs are changing too.
Any nuggets of wisdom to share on things that I need to make sure happen for the move to be successful?
Here is my list so far:
- lower TTLs on A records in DNS to 600 seconds at least 24 hours before move.
- prepare to update IPs in config files for each server for networking, firewall, email servers, apache configs andresolv.confs.
- ensure backup MX is ready to handle the load.

A chicken or egg type of problem with potential to escalate into an egg on the face problem.
I have two VPS accounts with PowerVPS, which we need to move to one new VPS account. Problem is I'm not sure how to handle the DNS move or settings to minimise downtime.
Currently the DNS is spread over the two VPS accounts. How do we keep the same DNS names and move to one new VPS without dramas?
PS. Before you say "ask PowerVPS", they don't support DNS config on two VPS accounts.

we're a webdesign company who also sell hosting (white labled). we have over 500 websites hosted with a company (based at telehouse in london - which is a good selling point for us when selling hosting packages). Theyve been really good (reliable servers, good support, good control panel etc...). Theyve also won awards for the reliability of their servers. Unfortunatley, over the past year we've noticed theyve raised their charges by quite a bit and the support has been very poor.
My question is: does anyone reccommend a company we can move all our sites to? this is obviously business critical (not only for us but for all our clients too!), and so we want to be absolutely certain of the company and what they can offer before we move over everything.
We've thought about a dedicated server with 1&1. It would be a fraction of the cost, but I always believe in 'you get what you pay for'. could this be the case here?
