View 5 RepliesI've got a LAN setup that share an internet connection with some friend but unfortunately we have a "Limit" we can download per day.
One of my friend's seems to enjoy downloading movies day in day out till we reach our cap.
Now I know ingress shaping doesn't change the fact that we are gonna reach our cap earlier but it might discourage him for downloading as much.
how can I shape his traffic to say 50KB/s both in and out for just an IP (so it doesn't affect the rest of us ?)
I just got a quote from a colocation provider but they said their standard policy was to customise traffic shaping for each customer..
The term "traffic shaping" on a server screams "bad idea" to me..
Being honest, my knowledge of shaping is limited.. but I don't want traffic shaping on my cable connection nevermind my server.
I am just in the process of setting up a new rack for some lower end clients.
At present we have both a local (National) and international traffic split. We need to offer our clients a 100/100 port speed on the national route/bgp/ip range but only a set amount on the international range. The port speed/throughput for international traffic would need to be as low as 128k/128k.
I would also like to have the flexibility to impose data limits on the international link as apposed to bandwidth shaping.
I have a spare Cisco 3750G-48TS I was hoping to utilize for the main switch on this rack (SFP Ports for multiple uplinks, National/International)
Hardware/Server wise what will be the easiest way to achieve this?
Is there a way to use traffic shaping in Linux? Like limit traffic to certain port, set priorities etc. Like ex: I'd want to set FTP to use max of 1mbps, http max of 80mbps, and set total to 90mbps.
Also is there ways to setup dos protection within linux? What I'd basically want is if it detects a dos, it either turns off the server, or does some other action that would cut it off either until I take action or for a set amount of time. Think turning off would be only solution since if I just drop packets I'd still be paying for that traffic.
Basically I want to ensure that if I get a DoS I'm not stuck paying insane bandwidth overcharges. I rather have a few days of downtime to deal with, then a few thousand dollars to pay and me having to declare bankruptcy and sell property etc...
I was checking out the switch products from Cisco and I noticed that there is quite a few products that been discounted, and I am trying to find correct switches that does traffic shaping on port for inbound and outbound.
I preferred they are 48 ports with 2 Gigabit uplinks, with Enterprise L3 image and it is little difficult to find the correct older models that is being sold on ebay to pick up the correct one.
I am also open to Extreme and Foundry switches as well, but I rather like to stick to one type for deployment, since I am working on the plan to deploy 2 core switches which all edge switches will hook into it.
Currently we are using D-link 3026 and 3028 switches (Layer 2 switch) for our bandwidth shaping and mrtg graph.
But it seems unstable, etc sometime it might congest due to unknown reason, even though the particular server is not fully utilize their bandwidth yet.
So we decide to plug in our Linksys SFE2000 (Layer 3 switch) and everything goes smooth once again. But, we never really setup the linksys switch yet.
Can anyone recommend us what kind of switches we should use, is the best choice for bandwidth shaping / QOS for the amount of less than $ 600?
What traffic monitor would everyone recommend for sites that have as many as 5,000 to 10,000 hits an hour?
View 8 Replies View Relatedmy linksys switch comes with a web control panel under "qos" where i can control bandwidth there is Ingress Rate Limit and Egress Shaping Rate, what are they?

View 8 Replies View RelatedI'm up Games for Windows VPS servers with VMWare Server ESXi and wonders whether some option to control the traffic of each IP, I thought about using a "Cisco ASA 5500" but I do not know if it has this option:
Example:
IP 192.168.254.1 = 100GB monthly.
IP 192.168.254.2 = 50GB monthly.
Etc. ..
Imagine you want a set of servers (VPSs would be a cheaper choice, that is why I am posting here) that do not have much outbound traffic but download from other servers (more or less as spiders, but I am not trying to create a web index). Disk space or memory size are not important, but port speed and monthly transfer should be as high as possible. As inbound traffic is less frequently used, I wonder if any provider offer cheaper rates if traffic is like this.
I have been searching the forums and have not found too much about this topic (a quite related post named "I want to download the Internet" or something similar did not get a conclusion).
I am not sure if my dedicated server is being attacked or if it is legitimate traffic. I need help figuring out the difference and if it is an attack, how to prevent it, and if it is legitimate traffic, how to configure the server to handle the load.
My server information is below:
HardwareIntel Xeon 3220-Quad Core [2.4GHz
8GB DDR2
SATAII 500GB
SoftwareCentOS 5.3-32
Apache2
MySQL 5
PHP 5
When I do ps aux|grep httpd|wc -l I get the count of current connected clients of 259 which is always maxing out my MaxClients of 256. I had increased it to 512, and it maxed out, I had increased it to 1024 and it maxed out, and lastly I had setup to 2048 and it works, but slows the entire server down.
if anyone knew of anything that maybe could be done to limit this band-width stealing by AVG or are we just going to have to live with this?

Recently I noticed the load on one of my servers way beyound what I would expect it to be. I run multi processor servers and even during a backup the load is only around 1.5.
But lately I noticed peak loads that high under normal web traffic.
I know 1.5 is low on an multi processor server, but I am hoping to add much more to those machines and with sustained load that high it leaves no room for expansion. The servers are not cheap, so adding another server to the cluster can only be done if I make money from the last one I added.
I checked the traffic levels and they were very high. After further review I had some bots hitting sites at over 1200 pages a minute. Multiply that by a few hundred bots and clearly I could have a load issue. The potential is there to bring any server to its knees when delivering those volumes.
I created programing to watch connections and block the abusive bots. While logging I became aware of over 600 bots crawling my servers. Many bots from, Japan, China, Germany and so on and on, useless to my customers even if they are legit search indexes.
Another problem I see is that the bots are running from many ip addresses and hitting the same sites from multiple ips at the same time. Why would the need to do that?
Among other things I decided to validate googlebot, msn and yahoo with dns lookups so I could determine that they were actually their bots and not imposters. In 24 hours I found valid bots from the big three hitting one server from 1100 different ips.
Now we are looking at thousands of vaild bots and thousands more email harvesters and content theives.
As a host, the number of sites I can host on a server is greatly reduced by the bot traffic. My customers do not want to hear that their website was being crawled at 3,000 pages a minute and that is why they could not access it. Of course they will blame it on me.
I was able to filter the bots at a firewall level and drop connections based on reverse dns lookups and site crawl rates and my server sits around 0.05 most of the time even with hundreds of pages a minute being accessed.
I am wondering how the rest of you hosts deal with this problem. Do you leave it up to your hosting customers? Or do you have some type of filter to get rid of the bots.
When you have a few sites it is not really a problem, but as you grow it grows exponetially out of control.
i need co-location to 5 servers 5U 5 ip adresses 4 TB traffic month i can share the cage with others Price ? my budget is around

I want to be able to monitor (with statistic) and cap traffic on 3+ servers.
how is this done best?
I was thinking of somekind of switch or server set inbetween the servers and the internet monitoring and keeping data on the traffic use etc.
but what do you do?
and how to make such a monitor redundant so if it fails the network is not cut off from the world?
i've a vps with iptables, but i've too much traffic (RX), there are too many packets received from random ports on both upt and tcp. Today in just 14 hours i've 2.8 gib of traffic, without any connection for web, email, etc (i've stopped all the services). How can i stop this? it's going to burn all my monthly traffic
View 5 Replies View RelatedI've only ever had a shared hosting account with Hostgator, plus a few freebie hosts. However, I'm now pulling some heavy traffic and I'm concerned that Hostgator is going to suspend me soon.
My traffic on Saturday for example was ~2600 unique visitors and ~5000 page views. All of this traffic was from WordPress blogs and a small SMF forum. I've since converted one of the blogs to a static site to limit my CPU usage and I've setup caching for my other WordPress blogs. Advice I've heard on the Hostgator forums is that 7000 page views per day for a database driven site is around the time you should be upgrading and based on my traffic from Saturday (which admittedly was a bit of a spike) I could potentially be receiving 150,000 page views/month, so about 20x the point at which they recommend upgrading at.
Anyhows, in a nutshell I need to upgrade, or risk Hostgator throwing a tantrum at me ... but I don't have a lot of cash to pay for an upgrade Due to my lack of cashflow I've been considering moving to a VPS. The company which has interested me the most is HostV.com who offer a 256 MB (with 1000 MB 'burst' RAM) for only US$39.99 which seems quite reasonable to me.
They say that their 256 MB plan should be able to handle over 5000 page views per day for a WordPress run site, but I'm a little suspect. Do any of you know if this is a reasonable expectation from a 256 MB chunk of a virtual server? I have no idea and am always wary of believing the sales pitch of a random company across the other side of the world.
I just want to ask. my ISP told me my server is generating high traffic from outside and paste me their traffic log with 1 IP address (xx.xx.xx.xx)
They rebooted my server and the problem disappear but I need to check what has been going on and where do I start? The only information I have is the IP xx.xx.xx.xx
I just recently upgraded my website from WordPress to WordPress Mu.
Everything went smoothly except for one problem. On WordPress, all my posts would appear as [url] but with WordPress Mu, it is now [url]. So whenever someone visits ht[url] or [url] they are given a 404 error because it no longer exists at that location.
I know there is a way, like a wildcard or something, that makes it so that wheneever anyone visits [url]anything it would change it to[url]whatever else was typed/, no? I can't figure out how to search for that exactly and tried reading through .htaccess docs and can't figure out how to make this work.
I have 4 sub domains on qisoftware.com and most have network traffic between 30-34%. Unresolved traffic about 12-14%. Is the network traffic statistic high? What would be considered normal?
A proxy server can mask IP address, right? Does a proxy server show up as network traffic in site statistics reports?
Okay, maybe that's enough questions for right now. I have been researching the internet for terms but I am not finding what would be considered normal.
An ad-network requires my website to have certain amount of traffic for x days to qualify, but they won't provide stats and have asked me to log the stats myself.
For incoming traffic stats, I already use AWstats etc, but is there anything available for logging outgoing traffic as well?
In my cpanel server, a site is getting too much traffic.
The bandwidth usage is some 60 mbps because the site is in digg home page, the site provide some file downloads.
I don't want this site take too much bandwidth, other sites on the server is getting dead slow.
Is there any way to limit usage by this web site?
Don't know if this is the right place to ask for this but here goes.
I have a 20U rack space and i use 4U of this space (1U + 2U servers and a 1U switch).
There is a 20Mbit internet connection on a 100Mbit network.
But here comes my problem, some friends have there servers in my rack space to, There is 12 servers that are my friends and i want to know how much traffic they use.
I want to know how many GB traffic they use to i can charge them (they don't pay right now).
2 of my friends servers must max take 50gb traffic!
Is there a switch that can do theys two things?
Show traffic and limit traffic?
i have an VPS account at SolarVPS. I have had some bad days lately. When i go to Virtuozzo on my Plesk cp. i see this
day - in - out
12 0.00 0.01 13 0.07 0.48 14 0.06 99.61
why is it like this? i don't used like 20GB last month (for all of my sites). but now it goes up to 100GB???? Why is this happening? how can i stop it?
i have already an dedicated server, but with an strong traffic limit, so i search webspace (filespace) for my thumbnail images, the space is only for the images, no php scripts or databases are needed just imagespace.
the hoster should tolerate adult content, and have no problem with 500gb bandwith per month. Paypal should be accepted as payment.
its important for me that the webhoster follow their offers and dont kick me if i use high bandwith....
Is it possible to limit internationally traffic? National would be Australian bandwidth.
For example;
Offering Unmetered national bandwidth and 10 GB international bandwidth.
OR
Offering 50 GB national bandwidth and 5 GB international bandwidth.
How would you go about doing this, tracking it, managing it, etc. Is there any software that does it already? For example Xen or Virtuozzo?
What are your recommendations for a high quality, high traffic firewall. Something for a colo center for a webserver, that is not too expensive.

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?
