My host has told me that my forum is coming under a DDOS attack. Once was on Friday March 20th and again today (monday march 23). Before those two, there are attacks almost every week, sometimes twice a week.
The host installed DoS-Deflate. It started blocking legitimate traffic and had to be removed.
The operating system is Linux CentOS, the forum software is VBulletin. The server is a VPS with 1 gig of memory.
Besides DoS-Deflate, what other options are out there?
I have searched for prevention methods and explanations on what DoS's and DDoS's are capable of. I was hoping someone could shed some light on free alternatives that would help reduce these attacks or help to make me aware if one were to occur.
Linux Distro: CentOS 5.3
I am not running apache or any web related services on my machine.
I run a dedicated server for the sole purpose of hosting a few game servers. I have already contacted my provider and they offered a $599 /mo plan for prevention. This is unreasonable and I simply cannot afford it. I have been threatened with a DDoS because one of my administrators banned a player constantly creating drama, stress, and breaking rules.
I simply cannot afford a gigantic bandwidth bill and this scare tactic has made me a little weary. Is there anything I can do to reduce the damage?
I've got a dedicated with Centos 4.x, WHM / Cpanel. I have problem when create new account, this is error:
Setting up Mail & Local Domains...localdomains...valiases ...vdomainaliases...vfilters......Done

I would like to know what are the best ways in preventing a UDP D/DoS Attack. DDoS-Deflate and most programs like that are just for TCP connections, and most of the time only for port 80. What is the best option out there for protection (linux wise) for UDP attacks. I was using shorewall before but it did not do so well so I just switched now to CSF [url] with WebMin and seems to be working ok. Even though thoes are both firewalls, they seem to have some protection against UDP Attacks. Please note this is a server that just hosts some game servers, no webhosting. What would be my best option here?
one of my clients seems to be attracting unwanted attention, it seems as if bots or something along those lines are attempting to exploit my box, while they are unsuccessful it would seem. I was wdonering if there was a rule I could put in Mod_Security that would ban them for attempting to
GET "/awstatsf/logger.php?action=log&type=Hybrid&host=hacked101&"
I recently initiated "Hot Link Prevention" on one of my web sites on my Dedicated server (via CPanel). It woks well in re-directing hotlinked images to a small image that says "Unauthorized Hotlink Image." This of course prevents other web sites from leaching my bandwidth. However, I have had a number of people complain that when they visit my forum, they don't get my site's images, but instead see the Unauthorized Hotlink Image. The common thread seems to be the people with the problem are using Security Software. In one case, a guy is using Norton Confidential. Another guy is using some Security software provided by his ISP. I'm guessing that this security software is somehow messing with the Referer in tehir browser and confusing my server into thinking the images are being hotlinked from some other site. Short of turning off Hot Link Prevention, does anyone have any suggestions to tell the folks...are there settings in their Security Software for example that will prevent the problem when they visit my site?
it's come under my attention that dragonara.net has been ddosing me today since morning from the ip: 194.8.75.229
What's so ironic about it is that the ip is from a UK DDOS protection site so i'm expecting some email with their services in the next hour or so. Stay clear of them they are fakes and e-terrorists.
This is more aimed at providers but do you allow partial upgrades on RAM/Disk/Bandwidth?
I'm asking as we have one brand which is fully automated which I refuse to do partial upgrades on as its done as a budget and if a user needs more they need to upgrade to the next package but it is budget.
On our more expensive brands we do allow partial upgrades
I backup my accounts via cpanel backup. I run incremental and mount to a NAS. I have about 2GB in database and 3GB in files (500,000+ PNGs). Backup is hard on the server and it takes 17 hours to complete according to my logs.
I host several web clients that were recently impacted by the crap at ThePlanet. As I think about how to be more redundant (and repetitive) I'm not sure of my options.
What's the best practice to ensure that if you have a server at a data center that goes out, that you can (somewhat) easily switch over to a different server? I suppose one solution is to have 2 servers at 2 physical locations, and then you could just change the DNS record in the event of failure, but is there another solution I'm not aware of? Is there a good resource I can goto to read up on this info?
Still considering co-location and have been for many months! One thing I'm now thinking of is firewalls. What firewalls are available to me, what functionality do they have? What kind of additional protection can they give against DDoS attacks?
I really have no idea where to go with hardware firewalls. The bandwidth going through the firewall on average would be no more than 10mbit/s. Perhaps 20 with growth!
how you went about setting up your colo space with firewall protection
I'm reseller vps, and now i decided to run own node, and sell vps, i choosed VDSMANAGER control panel, because virtuzzo is expensive.
Please help me to choose best options to run best and quality node,
VDSManager or VEportal ? (good optios&security&support&...)
XEN or OPENVZ ? (uutil now OPENVZ best for run static and dynamic site, but on xen can be run vpn & shoutcast & windows & linux & ...) RAM GB ? CPU ? Hard ?
can i use load balancing for vps node ? how many vps can be run on this node ?
I am selling custom software and web-design solutions. After my "unforgetable" experience with PayPal and 2CO i have found URL - they are new on the market and this is why they are more responsive than PayPal, whose priority is quantity, not quality. Most probably there are other option as well - simply this one is the most acceptable for me as it does not require complicated registration process/documents. I don't know how to get a normal merchant account if you live where I live.(I am from Ukraine). Please advice me some merchant accounts with their full discription.
Currently I cache php to html in a folder, and any time I upload index.php the whole site recaches. It also is set to a specific time such as 1 day, and the specific page will recache on someone hitting a page in 1 day from last cache.
The problem is when there are thousands of people on, and the index.php is uploaded the site crashes due to connections to the database, and possibly writing to the folder as well.
What is the best way to cache these files to html, and not have it crash every time I try to update things on the site. Also it needs to be something somewhat simple.
Just curious if any of you know of good ways to handle the bandwidth costs associated with hosting high traffic video sites.
For a future project I plan a dedicated server, but was hoping there might be a cheap way to avoid bandwidth costs - such as Amazon S3 (however from my calculations this is an expensive option).
I'm currently working for a company who are looking to migrate there current business system and also create an e-commerce website.
The company (Company A) who were doing the migration were also going to originally take care of the e-commerce side of things aswell, but after looking at the website solution they have now decided to give it to another company (Company B) to deal with. But seem to be sticking with the original company to do the business system migration.
Now this has created a bit of a problem with regards to the hosting side of things (amongst other things ). Originally this was all going to be hosted by Company A. This would keep it all nicely integrated. But now Company B are doing the e-commerce side of things it needs to somehow integrate with the business database.
And now for the question (about time i hear you ask ). Can you give me the pros and cons of the following scenarios:
Scenario A: We host both business system (database) and webservers onsite.
Scenario B: Company A hosts business (database) solution. We host webserver.
Scenario C: Company A hosts business (database) system. Company B hosts webserver.
I've recently taken out a new server and the management company I use have indicated that the HDD may be failing.
My server memory usage has been pretty much frozen at 85%+ since it went live, and there is only one live site on the server thats not at all active.
Because of this memory issue the management company discovered the HDD issue whilst probing around.
I contacted the server provider and they have said because its a single unit system that the only option they have is for me to have a new HDD and a simple OS reload.
This poses a problem for me because I've paid my management company to harden and configure the server for me - If my server provider reloads, I'll lose all the work I've paid for.
I find it a little unfair that this has happened with a new (maybe reconditioned server) and that I'm stuck in such a situation, but as is life..
I'm just wondering if anyone could suggest what I might be able to do about this. Is there anyway I could perhaps take a full backup of the entire server and reload it from a seperate server? Is there a service avaliable that offers this sort of thing? I can't get physical access to the server so there is no way of me going there and backing it up myself.
My old/original server that I moved from is still active. I think the current server has like 5-10Gb used so far.
