Determine What Service Is Creating Traffic
May 24, 2007I'm using MRTG to display graphs of traffic to my server, and today noticed a period of several hours where there was a lot of *incoming* data over the network, which is unusual. There's a good chance it's some harmless script or service that I've forgotten about, but really I need more information on what services/ports are creating what traffic, which brings me to my question.
I'm wondering whether there's an easy way to check what services (or ports) are creating traffic, and what volumes of traffic. It would be nice if it was possible to graph or breakdown the traffic by service somehow, and determine which are the biggest users of bandwidth and when. This is a dedicated CentOS server that I can install basically anything on, but that doesn't use a control panel, so I'd like to see what great ideas you folks can come up with, or whether there's any nice software you can suggest. I'm only using the server for hobbyist stuff at the moment, so free software, or ideas using built in commands are preferable.

View 7 Replies View RelatedNagios With Service Check Notifications
Mar 4, 2008We are starting to use Nagios for some remote service checks (http, smpt, pop, ssh, etc..) and the notifications are not being sent out. We have the regular hosts configured and those are being sent out just fine.
Here's what we have currently:
Part of our services.cfg looks like this:
Code:
#### Generic services template ################
define service{
name generic-service;
active_checks_enabled 1;
obsess_over_service 1;
check_freshness 0;
notifications_enabled 1;
event_handler_enabled 1;
flap_detection_enabled 1;
retain_status_information 1;
retain_nonstatus_information 1;
register 0;
}
define service{
use generic-service
name basic-service
is_volatile 0
check_period 24x7
max_check_attempts 15
normal_check_interval 5
retry_check_interval 1
notification_interval 20
notification_period 24x7
register 0
}
define service{
use basic-service
name dns-service
check_command check_dns
max_check_attempts 10
check_period 24x7
notification_interval 20
notification_period 24x7
notification_options c,r
contact_groups localadmin
register 0
}
#### HOST01 ######
define service{
use dns-service
host_name host01
servicegroups mygroup
service_description DNS
contact_groups localadmin
}
To me, that looks correct. Host01's service check should inherit
everything through 'use dns-service' line.
checkcommands.cfg file for DNS:
Code:
# 'check_dns' command definition
define command{
command_name check_dns
command_line $USER1$/check_dns -H $HOSTADDRESS$
}
contactgroups.cfg:
Code:
define contactgroup{
contactgroup_name localadmin
alias Site Administrator
members nagios
}
contacts.cfg:
Code:
define contact{
contact_name nagios
alias admin
host_notification_period 24x7
service_notification_period 24x7
service_notification_options w,u,c,r,f
host_notification_options d,u,r,f
service_notification_commands notify-by-email
host_notification_commands host-notify-by-email
email mail@domain.com
}
I believe the above should be correct since I have host and service to
be notified by email. Obviously I'm overlooking something.
Service To Check If An Email Is SPAM
Jun 25, 2008We have a script that will be sending out emails from our server. A few already have hit the Outlook SPAM folder. The email that's sent is a validation check, where the user has to click a link to verify an account.
Is there some service out there where you can send it your email and it will tell you if and then why it will be caught by leading spam filters?

May 29, 2009I'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 192.168.254.2 = 50GB monthly.

VPS With Mostly Inbound Traffic
Mar 24, 2009Imagine 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).
Overload Of Traffic
Jul 2, 2009I 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.

How Do You Deal With Too Much Bot Traffic
Oct 28, 2008Recently 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.

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?
Traffic Shaping An IP
Dec 11, 2007I'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 ?)

View 5 Replies View RelatedCan A 256 MB VPS Handle My Traffic
Apr 1, 2008I'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.
High Traffic To Outside

Traffic Shaping
Feb 20, 2007I just got a quote from a colocation provider but they said their standard policy was to customise traffic shaping for each customer..

Being honest, my knowledge of shaping is limited.. but I don't want traffic shaping on my cable connection nevermind my server.
How To Do Redirect Traffic
May 7, 2007I 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.
Network Traffic
Dec 13, 2007I 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.

Too Much Traffic From Digg
Oct 13, 2007In 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.

Is there any way to limit usage by this web site?
Monitor Traffic
Apr 2, 2007Don'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?
