Tools To Measure Server Connectivity Times
Nov 6, 2007
I've got a housed server within my customer's datacenter. I consider application runs ok, but it goes very slow.
I consider it's due to their connection (DSL) and installed another provisional server with a simple "Hello World" and no traffic. I'm to install the same server within another datacenter, and would like to find an external tool to certify connectivity times.
Do you know any of these tools? I'm not searching tools like 'Apache AB' or 'HP httperf', but public online services.

Is it possible to install tor on a server, and serve up websites using the Tor connectivity/proxy IP (not the server's real IP)?
If yes, what's the procedure for setting this up?
And should all nameservers continue to resolve to the server's "real" IP(s) or...?

We have a VPS with Media Temple. Their data center is somewhere on the westcoast. From time to time we have severe issues to connect from our Brooklyn/NY locations. We experienced the connectivity issue from 2 physical locations. Doing a tracert gave us a good result.
There are usually 4-8 users using our shop admin for order processing or the shopping cart for manual order entry. While they are having problems connecting from there, I can connect just fine from Calgary/AB, Canada. Most of the time no issues at all.
how to debug that?

I ordered yesterday, and got it today! But I have the box, 100 MB unmetered line, I downloaded utorrent, donloaded a file at 10 MB/per sec, but For some reason the box wont seed, and the tiny little yellow banner on the bottom says there are no incoming connections (this is usually green if your port is open) It wont seed... the DL is great, is there a box setting that is blocking this? there is no installed firewall, and the ports are all open....

There are several methods of offering network path redundancy. The basic decision for me has come down to:
Do it at Layer 2
Do it at Layer 3
At the moment we have layer 2 redundancy to each server. 2NICs on the server up with one having the IPs for apache/mysql/etc. each nic going into a seperate switch and the switches connected together, with 2 routers running VRRP to handle the gateway.
Everything is Vlaned.
So basicaly the switch redundancy is done by spanning tree and the IP redundancy is done with a process on the router/server to move the IP to the other router/server NIC if there is an issue.
I am thinking about going with 2 fully seperate networks. in differant subnets. where each router would have a gateway. the routers would talk to each other and they would speak OSPF or ISIS with the servers. This way I would move hosting onto loopback IPs on the servers and those loopback IPs would be advertised to the both routers through seperate networks.
Again everything would be Vlanned.
This has the advantage of getting rid of spanning tree which has caused issues from time to time. It would keep redundancy up and we could standardize on the routing daemon ran on the servers allowing all of the various OSs we run to have the same basic config for network redundancy. Where now each OS tends to have its own solution. This would make life easier from a config and troubleshooting point of view.

Are there any good tutorials or tools for Serer Hardening on CentOS?
Additionally, any good Host based IDS units along those lines?

When using domaintools.com to see what sites are on a server, sometimes it says dedicated server. Does this mean that there may be several sites on that server and it is just that the domaintools.com service cannot find out what the others are?

Can you please tell me any free server/ services monitoring tools available.
I would prefer third party services rather than installing something on the servers unless its the only option

Are there any tools out there that can monitor the uptime of my server (of my websites)?
Maybe an application that keeps pinging it throughout the day or some type of web-service?

Lots of things have improved in the last 5 or so years with regards to hosting.. faster hardware, improved control panels, cheaper bandwidth.. but the ability to keep your eye on your box whilst out and about is definitely amongst them I'd say.
So share your tech tips for when you're not at your desktop for monitoring your sites.
Key hardware: My iPhone. 3G is prevalent in my locality, but the deal on o2 means I also get free access to the two largest UK public wifi hotspots - TheCloud and BT OpenZone. Whilst some of these are free anyway (such as ones in pubs) being able to walk through town whilst on a wifi connection can be really useful if the 3G is lagging or just not there.
Software:
Pingdom - It's not the flashiest of all apps, but it tells you what you need to know - is the server up?! It'll echo all your reports for all servers into one quick and easy screen. I really hope Pingdom puts even more time and effort into this, it could make the service unbeatable with a few more features. The app is free too, which is a bonus.
TouchTerm - there's a bunch of SSH clients for the iPhone out there, I've not had chance to try any of the others but will do at some point. All my accounts are bookmarked in and I can replicate whatever I need to with ease. I've installed software and configured it with relative ease just using the touch keypad. It was either free or at most a dollar or two.
iStat - The software/server combination used to be Mac only but someone has ported the server side over to *nix now and it runs pretty well. I'm having issues with one of my boxes showing it's bandwidth usage but I'll look more into that. Live CPU/Memory figures AND graphing?! Very impressive, and if you're doing face to face with your client it's bound to be a good thing to show off (make sure it's working first tho!!). It was £1.19/$1.99 on promotion when I bought it, should still be for a little more.
Critical email accounts IMAP'd - all my key accounts are on 15minute checks, and I'll be making an emergency PUSH account for when time is very much of the essence. Having instant access to email is absolutely essential on a handheld device these days, and the iPhone does a pretty neat job of it.
EverNote - great note syncing between various boxes. No more having to ring people to jump on my laptop to read me out an IP address or similar ever again.

What are some methods (software or protocol) of measuring total bandwidth usage and billing clients in a dedicated or virtual server hosting environment?
For example 3000GB of transfer per month.
Does this also indicate the total sum of up and down transfers?

Is there a site that anyone knows of that has detailed info regarding UPS aside from apc?
We are looking at expanding our UPS and Gensat but until now we had our colo company handle everything. With our new Building about to be lite we are still sourcing out our UPS and Gensat.
Total Built space is 2900 square feet with 4x 15 ton 4 step Lieberts.
we have total power of 800amp 3phase and would like to ensure from start we have enough to handle full load.
We have seen in past with colo company that over time they had to increase the size of ups during the years and this has caused downtime for clients. We want to ensure from get go that there is no power issues down the road so rather invest the money now to ensure we can manage a full load down the road.

I've paid for a site to do some harding of my new server and I'm not up to speed with it all yet.[url]
They say they've completed it but I can not find any config files for mod_dosevasive in my httpd.conf file. Is there a way I can check to see what packages or software or tools are installed on the server?
CentOS 5 with WHM/cPanel.

For those who do shared hosting, how do you go about measuring bandwidth per user? I'm thinking going by log files, but what about stuff like ftp, mail, dns, etc? Is there an easier way?

Some guys was ddosing my server and its get down for a while .. now i email my support asking them for help
they answer me
Hey,
We do monitor network traffic, and if we see something suspicious, we take action to resolve the situation. However,
t may be possible that if the attack is focused enough, that it may slip under our radar.
If you feel that you are being attacked, the best course of action would be to use your iptables to restrict traffic from the suspect IPs.
so now how could i iptables to restrict traffic from the suspect of my server IP?
my srv had installed csf firewall ..
I asked them if that free and they answer
Yeah, sorry, but our network monitoring is for our entire network. If you were wanting to measure traffic to your specific IP/slice, you would have to install some manner of third party monitoring software.
how to restrict traffic from the suspect of my server IP with iptables and measure traffic of my ip server?

if any of you could give a quick idea on the set up times for dedicated servers from ECATEL
I paid 515 euros 9 days ago, and the server still hasn't been set up (Hardware delivery problems I have been told) and before I ordered, they stated the setup time would be 48 hours.
Is this normal? The last email i received from them was 3 days ago.
I find this completley unproffesional, It is always another few days.
What are your experiences with them? I am utterly dissapointed so far.

way to keep server times synchronized? All servers are in the same location.
For example, a website has two web servers and one database server. What's the best way to keep the time syncd on all servers (they should be the exact same time really)?
Operating System: Linux - CentOS

I bought a VPS package hosted at Hosting-IE from someone I knew, since they were not going to be able to use it. Its a linux VPS, and it's done me well. Based on that I decided to purchase my own package, a Windows VPS.
After payment, I messaged support about a broken auto response email they sent out, then asked how long server setup time should be. They responded 1-2 working days. Fine.
Well, its been 7 days since then. I'm 1/4 of the way through the month I've paid for, and still no VPS. I messaged them back asking for my server or a refund, no responses since then.
My previous host set up my dedicated box within a working day, and that involved setting up the hardware too. Over a week for a VPS is too long.
Is my experience with Hosting-IE abnormal or should I be demanding my loot back? Is there any other VPS provider out there that can offer me similar stats at the same price as Hosting-IE?
for a simple package setup, this has gone on for far too long.

im trying to remotely install WS2003 EE R2 on a dedicated server I have purchased and have an issue. I'm installing it via KVM IP which is cool
however, after installing the network card drivers, I get a "There is no or limited connectivity" etc... so I cannot access the internet or anything on that box.
what do I do from here? how can I make the card work? It is configured to obtain the IP Address automatically as well as using the default DNS. I do have 2 IP Addresses "assigned" to me/my account but dont believe I need to configure them in WS2003?

Is it better to have a rack in a carrier neutral datacenter and get feeds to the rack from various diverse carriers.
Or
Is it better to have a rack in an ISP datacenter where they provide the connectivity for you?

is anyone else having trouble with burst.net at the moment? from two locations, i'm having problems where anything that will elicit a large response just hangs indefinitely. i can ping my server just fine, i can shell into it... if i do "top" or "dmesg" or anything else that might dump back more than a few lines of response at a time, the ssh session hangs. i can do "ps x" as a regular user, because i only have two processes running. "ps ax" will hang ssh.
none of my websites work, and i can't get on the burst.net website from either location. i tried calling but no matter what sequence i try for (even tried reboots) i can't get ahold of a live person, but then again it is almost midnight.
anyone else experiencing this?

I have tested so many compagny I can't even remember and with all of thoses compagny my customers had lagg pikes or this kind of things.
I am hosting a gameserver service which required a top connectivity , most of my customers are in europe and I looked for the best dedicated provider in europe.
I tested OVH , ngz-server , bestserver.eu and much more but it was the same problem.
If someone know a good dedicated server provider in europe using premium bandwidth with good carier and not only with peerings .
I have looked a bit at serverboost.nl they seems serious but I have no feedback about them.
If you have any provider with a top connectivity it would help me a lot to choose what deserve my customers.
A DDos protection is a must also (not for bigg ddos but littles one ).
