I have a dedicated windows server. I have it protected to the best of my ability (disabling administrative shares, anti-virus, anti-spyware, disabled remoted desktop, firewall, etc.). The purpose for the server is to host game servers. Over the past month, ive noticed massive amounts of bandwidth being used. For example Windows reports the bandwidth usage at a little over 2 GB in 1 day, yet on my control panel which reads the traffic from the switch, it shows that 9 GB have been transferred. I asked the colo what's happening and they said that traffic that is blocked by the firewall is still counted toward my monthly limit. But how can there be 7 GB of blocked traffic, keeping in mind i never had this problem months ago. As a test, last night i disabled all game servers and applications that use bandwidth. In the past day over 9GB has been transferred, despite the fact that i have nothing running that takes more then 50KB of bandwidth.
Aside from these bandwidth issues, everything is running fine, my passwords are still the same, etc. Is there anyway detect security holes, so that i may patch them when i reinstall the OS? I asked my colo for a security audit.
My question is, do you think my server has been compromised?
Everything on our Qmail installation is working fantastic except for one thing (most of the qmail patches are installed from [url]:
If a user sends an email to several recipients, often times, all users of the list will receive several copies (10 times or more) of the email.
So far I think the situation is that a user sends a weekly update (sort of mini mailing list to 20 users or so) by just adding them as BCC in their outlook. Then I think one of the 20 emails bounces or throws back a deferral, and then qmail resends the email many many more times not only to the bounced recipient (but also to the entire list of recipients in the BCC)
I have a problem with a customer. For the last 48 hours he has been receiving a massive DDoS at his server. I tried blocking the darn IPs but they keep coming and with several hundreds of connections each:
Apache has over 14000 connections. I tried using mod_evasive but didn't do anything and the server has been out without httpd for hours now. Any advices? This is a Hsphere server (I hate it personally) with 4GB RAM and a dual optero 246. I have the mexclients setting at 550.
How can I better monitor and trace down I/O spikes? I've noticed the wait hit 60% every now and again... could someone be running a rapidleech script and if so, how can i find it?
I want to prepare myself for getting dugg and whatnot, so I want to mirror my site ahead of tiem. The problem is that it's very db-intensive so there's a db that all mirrors would have to query. What's the best way to deal with multiple dedicated servers in order to spread traffic load and not crash my site?
I've noticed that vBulletin and one of my directories is getting hit hard for the same file by sites in the Netherlands, Russia, Vietnam and China.
The lines typically state the same, trying to hit a file that isn't there, which may be in a forum/ or forums/ directory instead of the root.
'/home/mysite/public_html/forumdisplay.php' not found or unable to stat '/home/mysite/public_html/newthread.php' not found or unable to stat
What have you guys done for this? I'm assuming an .htaccess edit may be in order. I'm also hoping to track IP addresses so that I can keep adding them easily. I wish it was more simple to do it on the server level using whm since it's usually accessible everywhere.
Can any suggestion a host, and incidently perhaps the best album script, to host as much as 100,000 photos? I'm not sure size yet, but 10-15 gigs is expected. Currently there's 40k photos, but I'm leaving room for expansion.
Recently I changed server providers, so now I'm looking for a way to transfer all the data to my new server. I have a total of 420GBs of files in my secondary HDD that need to be transferred.
The old server is at a 10Mbps line, the new one is at a 100Mbps one. From old server, less than half the pipe is being actively used. So theoretically, I should be able to transfer it all in about a week.
I tried 1) SCP. That was waaay too unreliable. And I couldn't get it to restart from the point left on whenever the transfer stopped (like when the servers were restarted).
2) Transfer using a web script. Way too slow, got to about 35GBs, total would take like 2 months.
Is there any other, reliable way of transferring data from server to server?
I am trying to figure out what file system to use for my server. It has 24 hard drives, 2 run the OS in RAID 1, and the other 22 are in RAID 10. When I was installing the OS (Ubuntu 8), I kept on getting problems when I tried to partition and format the second drive (the one with the 22 disks in RAID 10) and it keeps failing on me. I then changed the file system type from ext3 to XFS and it worked fine. I also gave it another try and did not partition/format the second drive and decided to do it manually once the OS was installed. When I did it it told me that the file system was too large for ext3. So my guess is that ext3 has a limit on the size of the file system it is being installed on.
Anyway, so I am wondering, is there any other file system that will get me the best performance, mainly I/O performance, that I can install? I would like to stick with Ubuntu OS. This server will mainly serve large files for download over HTTP.
how to handle the file storage of a youtube clone?
Is it just a matter of getting more servers with a few hdds or are there specialized companies that one can upload files over a distributed file streaming network?
The reason I ask is because I have thousands of gigabytes of videos and it appears to be impossible to upload it on 1 dedicated server or even a few.
to change all passwords for user account on cpanel server. Is it possible to do it automatically by using some cpanel script? Also I need this information stored in one file in order to know new passwords.

Its a cpanel box with suphp enabled, and all the exim tweaks you can imagine (ie, prevent nobody sender, max 50 mails per domain per hour, send callouts disabled, etc)
How will I assign the bandwidth for a VE in virtuozzo power panel. I could not find any fileds that corresponds to bandwidth in the steps during creation. I could find how to restrict memory(vmguarpages) and disk space. But where will I assign the bandwidth that a VE can use.
Now I keep very close tabs on my site stats. Just tonight one of my sites suddenly showed 167gb for "traffic not viewed".
That was a jump from 5gb over the course of a day.
That was done in 604877 pages and 607138 hits.
Can someone explain to me what "traffic not viewed" actually is within AWSTATS.
Next I located where most of the bw went and it appears to be http code 206 showing 159gb. My latest visitor report for the addon domain only showed one ip with an odd couple direct requests. The referring site was my own cpanel but registered to a ip in India.
How can i locate where the leak is, latest visitors isn't being much help, I have since denied the india ip which i suspect was the problem maker. How can I prevent instances such as this in the future? Being a streaming video site I have the bw to spare but it is still a bit un-nerving. Now on top of everything Virtuozzo isn't showing anything of the sort, what do i believe?
I like the LSN server company and have a server there that I plan to keep forever, they do a great job just that I am confused about their bandwidth. Also the prices aren’t exact!
Just wondering what everyone else here thinks about this:
So... LSN are doing a Q9300 server at the moment for $130 “ish” with 2TB of bandwidth. Now let’s say someone wants an extra 0.5TB of bandwidth they pay around $50 for it and if they want 1TB they pay about $95.
So you buy a server for $130 and get 2TB of bandwidth and also the costs of the hardware, space, power is covered for the hardware. Yet they charge nearly the same price for 1TB extra to a single server, which uses no extra space, hardware or power. Another thing is they charge $25 server to pool the bandwidth between your servers.
So as you can see from the above you can get twice the space, RAM, CPU and Power for only $10 more? Surely it costs them more than the $10?
Also my final point is LSN have a private network, that is not bandwidth monitored and your servers can use, I asked LSN if you could tunnel the traffic from one server to another, their answer was “yes if you have the technical knowledge to do so”... Well that would get rid of the $50 pooling costs... making it actually alot cheaper to get two servers.
I'm looking to get a VPS offshore (please look at my other threads/posts to learn why) primarily for email for 4 or 5 domain names (most of which I'd download to my desktop but would also backup on the server) as well as perhaps to run a virtual desktop through and/or store some data.
For ease of use (for ME at least), I'd install (or have installed) a CP and probably run Centos 5 or Debian as the OS on the VPS. I won't be running websites from the VPS and I'll be the only user.
I've seen offers of all types related to bandwidth but, in some countries, bandwidth is expensive and they offer little as a result. How do I determine how much bandwidth I need for what I want to do and how do I know what's too little?
I have a server with a 10Mbps connection. Is there a way to limit the connection of my VPSs?
Lets say I have 10 VPS on that server, is there a way to limit them to 1Mbps each? Or do something like: VPS_01 = 0.5Mbps VPS_02 = 0.5Mbps VPS_03 = 0.5Mbps VPS_04 = 0.5Mbps VPS_05 = 1Mbps VPS_06 = 1Mbps VPS_07 = 1Mbps VPS_08 = 1Mbps VPS_09 = 2Mbps VPS_10 = 2Mbps
And/Or is there a way to monitor the data transfer of each VPS (how many GB/month)?
I've found a colocation company that gives me as the default 1.544Mbps as the initial bandwidth. I think this is OK for me most of the time, the problem is their bandwidth isn't really 'burstable', and If I want to expand to more bandwidth, my options are something like buying another T1's worth muxed in for $250.
Is this strange? Old-fashioned? Should I be worried about this?
I have a dedicated server and I would like to know how much bandwidth I use each month, this information is not provided in the control panel, is there any way to find out?
my plesk control panel for my dedicated server and with all 3 of my domains FTP and HTTP transfers I'm getting below 500MB this month. However, GoDaddy's control panel says that I'm using 486GB. So where could the other 499.5 GB of bandwidth be coming from? I don't have that much email going on. No file attachments or anything.
Is it better to pay for 95th percentile or (what ever that is) is it better to pay per GB used.
I pay per 100GB used and I can upgrade it at anytime during the month which makes it very easy to manage but I would like to more about the differences here.
My issue is and not really that big of one but when I have paid for 400GB and then on the last day of the month I go to 410GB and have to buy 100GB more so I do not get charged overages. I end up with 90GB left unused which someone is banking my cash on.
Besides that I think this really works well for me.
Hello all, I run a popular Canadian site called CKA at www.canadaka.net I am trying to improve the performance of the site and I am looking at getter another server to offload many of the other smaller sites I also host on my main Dual Xeon rackserver. At the same time I am looking for a new Colocation host, because I feel im paying way too much at my current host.
But something I am confused about is how much bandwidth I need. I am not talking about bandwidth in the data transfer sense, but in the connection speed.
Many hosts have options/packages ranging from 1Mbps to 100Mbps. Many packages with 1,3,5,10Mbps are "unmetered" where are 100Mbps is usualy metered. I'm not sure what speed I need for my site so that there is no bottleneck at peak times. Because the price difference changes a lot between these options, so if a 10Mbps won't have any noticable difference over a 3Mbps, why pay more?
I'm not really that imformed on all this, but i have MRTG setup on my server here: [url] so someone more knoledable than me might be able to better acess what I need?
As far as data transfer, the server uses between 300GB - 500GB a month.
