Constant Uptime Connections
May 5, 2008
I thought i'd just post a quick message on here to see what you guys make of this situation. It's only happened with what, the past hour or so, but when i check the visitor logs on our website it seems that a "YouMonitor.us" is constantly spamming connections to the website over 1 second intervals (even less than that in some cases).
Furthermore, its coming in from different IP address's all the time and therefore its inappropriate to block everyone as they seem to just constantly change.

I have in my possession a new server which is running cPanel. For some unknown reason it keeps crashing about every 4-6 hours where I must get a remote reboot done.
Its starting to annoy me that I'm unable connect to anything. What I suspect is high disk red/write. As what I'm finding is over 10k blocks being written per second with only 300 being read per second. I also am not seeing any bandwidth out/in usage being high.

I am wanting to get access to 'top -c' for a period of 48/72 hours.
Now I have found the following
Code:
top -c -b -d 15 > top.txt
What this does is every 15 seconds add reply 'top -c' to top.txt
Now I can make this into a shell script then put it into the background and exit SSH while leaving it running.
Now the question is will this use much usage/server load over the 48/72hrs, it will be checking 4 times every minute.

Today i was informed that some of Apache instances are vulnerable for serving content while client is constantly pressing F5 button in browsers - once is pressed CPU load is increasing, page became slow etc. (it's dynamic content served by back-end Tomcats). In the same time i see errors with connection between Apache and Tomcats' instances.
Is there any good way to protect Apache against it ?

My server is constantly crashing (halting to dead) and needing reboot literally every few hours. I cannot trace the cause of this whatsoever. Please help out.
CPU/Memory/MySQL Usage shows no accounts in red or yellow zone ....

I have a dedicated RHEL server with cPanel and my server loads spikes about +0.4 (out of 2.0) for about 30 mins every 4-6 hours or so. My regular server load is 0.01, because there is barely any traffic on the server yet, but by looking at my top processes in WHM, I can see that the processes that are spiking the Server Load when it is high, is something like:
sshd: [priv] root
sshd: [priv] root
sshd: [priv] root
sshd: [accepted]
sshd: [priv] games
sshd: [priv] news
sshd: [priv] root
sshd: [priv] root
sshd: [accepted]
...something along these lines. And a lot of times there are 10-20 of these sshd processes at one time.
My server is managed and my dedicated server engineer said it was probably a bot trying passwords. He took one of the IP's, said it was from Taiwan, and blocked that IP in iptables.
However, this is still happening constantly with different IP's. Is there a way to prevent this from happening? I'm the only person (and my host) who should be able to login to my server using SSH... however, I don't have a static IP and I work from multiple locations, so only allowing certain IP's won't work for me.
First off, is this normal? Or am I being attacked or what? What can I do to remedy this? It seems the bots haven't successfully logged in, but they are spiking my server load which is NOT what I want.

I was having issues with what I would like to think as power.
Now, I was wondering if there are any SQL database benchmarks, or something else I can run on the system for a given period of time, that will let me see if I'm still having those power issues.

I keep seeing sa login failure on Event viewer Application log for MS SQL 2005. I'm tired of blocking off the failed attempt ip. A huge portion of them seem to come from China and Estern Euro. Should i just block off those region? Is there a better way for securing SQL2005?

We first noticed the issue on July 19th, Backups were taking a while to transfer from our own servers, and we were getting tickets from clients asking why this was happening. At the same time, it took about 4-5 minutes to log into the backup console. Issue seemed to correct itself so that backups were possible, and we assumed that scott would be aware of it and would work to resolve it.
Again on the 29th it slowed completely again. We immediately dispatched an email to their support email asking whats up, gave them detailed information such as access to the script and the output so he could monitor it.
The same day a few hours later we got a response that he would run the script and monitor it.
On the 31st, after not getting an update I asked what was going on. He said he ran the script, it seemed to stall for long periods of time and he would know more in the afternoon.
After not getting an update for ~5 days I asked what was going on and I expressed that i was not happy with the lack of communication/updates ont he situation. He updated me later that day saying that we weren't the only ones being affected. Fair enough, he is working on it. Thats all I wanted to hear.
Now ever since that email I received on the 5th (AUG) it has been up and down and all over the place.
After seeing him post on the forums I sent him a PM (10th August), summed up it was basically saying I had an issue, and I need it fixed. I figured since the PM system is usually pretty good at not losing them that he would see it and respond accordingly, that way there was no chance of it being lost from point A to point B as an email.
Well to this day, no response nor resolution.
I really have exhausted all points of communication, and I want to make it clear that I am not bashing them, when it works it's great. But maybe someone else affected can provide more insight..

Not sure why, but for some reason lately our Plesk installation randomly sends us notification emails about alarm level changes which go from Green to yellow, yellow to red, then goes back to normal over time. No changes were made on the server for these constant changes and emails to occur. We have a customer who also has the same issue.. Both focus primarily on nginx with little to no usage of apache.

This problem has been reported before Plesk Panel 11. What's the current solution for this problem? I've got this problem since I upgraded to Plesk Panel 11.09.
I'm getting spammed with emails like:
Server health parameter "Services > Apache memory usage" changed its status from "green" to "yellow". Click to expand...

I had Plesk 10 installed on my openSUSE system (was a low version, maybe 11 or less) and then decided to upgrade to 11.5. So I did distribution upgrades to openSUSE 12.3 and everything went smoothly, except for some services like mysql and php. So I used Plesk autoinstaller to fix the php error and edited an outdated line in mysql configuration and both services ran smoothly!
Then I downloaded Plesk autoinstaller and ran the autoinstaller, but was surprised by this error message:
===> Checking for previous installation ... found.
ERR (3) [panel]: Error during product key mode determination, details: Unable to connect to database: ; trace: #0 /usr/local/psa/admin/plib/functions.php(2821): isPpaKeyRequired()

#3 /usr/local/psa/admin/sbin/httpdmng(8): include_once('/usr/local/psa/...')
#4 (main)
Unable to connect to database:
- My MySQL version is: 5.5.33 openSUSE package
- I did run mysql_upgrade with my admin username and password (password from: /etc/psa/.psa.shadow) and it worked successfully and fixed all of the errors, I did so after running the auto installer first, but then ran the installer again and the problem was still there
- I can access my web page, but it still doesn't connect to MySQL either.
I believe this is a problem with MySQL, but how can I make sure or detect what exactly the problem is

I am shopping around for a new dedicated server and am running into sites that offer 100% Uptime guarantees.
Is 100% uptime possible? Wouldn't that mean that they never reboot their server, or never perform specific maintenance/updates on the server?
I guess when I see 100% uptime, I would expect perfection. I thought I'd ask here if this is possible because I'd hate to invest dollars on something false.

A web will be down due to many problems, like disk failure, web services dead etc. even ISP offers 100% network uptime SLA. So, my question is how to keep a web 100% uptime?
for instance, when any server(either db server or web server, either hardware or software failure)dies, the redundant server may immediately and automatically take over the dead one.

how come every web host says they have 99.9% uptime? I just saw a new webhost that started last week and they said they had 99.9% uptime. They've only been around for a week, they should have 100%. Why does every web host advertise that fact?
Next, how is that .1% lost? Do their servers crash for a second?

It's my first post, but I thought it would be useful to create a list with links to public statistics of uptime of VPS's of different hosting.
Hyper-v windows 2003 vps at webspacedepot.com
serviceuptime.com/users/uptimemonitoring.php?S=8621c2c30f85e3fadc3d6f056170db65&Id=14678

I am getting increasing frustrated each day as I went from shared server to shared server and now I'm on a VPS and my server is typically down 2-5% per day. Is this normal? Is it to much to expect 99% uptime?

I'd be interested to hear from anyone who can point to independently documented evidence of uptime of 99.99% or better for at least 12 months for a specific site hosted on a commercial hosting company. (Less than 53 mins of downtime.) I'm looking for something like a link to a report on an independent monitor site (e.g. hyperspin, alertra, host-tracker) that has checked at least every 10 mins over that period.
We get a lot of requests for "reliable" hosting here, and I'm hoping this will be useful information - even if there are no responses!
I'm not interested in anecdotal reports or "near misses" - feel free to post them in a different thread, but not here, please.
If you respond, could you please indicate whether the monitored site used scripting (e.g. PHP) and/or database access (e.g. MySQL) during the entire 12 months and whether you used this host for email, and the price you actually paid for this hosting package?

As I've mentioned in other threads, I work in the hosting industry at the support end of things. I can't go more than 10 minutes into my shift each day without seeing a ticket where someone is complaining about or contesting the "99% uptime guarantee". One day a couple weeks ago, I had someone complaining about an Alertra report with 98.7% uptime, and how it was unsatisfactory for their site to be down for 10 minutes every month. What's more, it was just a stupid World of Warcraft forum that probably saw 5 visitors per day.
My co-workers and I have been debating this, though. What worth is there in 99% uptime? Is it something that can be achieved? If so, would people pay more for it? Would it be able to be marketed to the shared hosting community? Would people be willing to pay more for 100% uptime? Would the same answers apply?

I have a VPS and am looking for a way to show existing and potential clients the uptime levels of the server. I have a basic uptime page provided by WHMCS, but I want to go a little beyond that.
If I were to choose an uptime reporting service such as siteuptime.com, hyperspin.com or site24x7.com, what would you recommend that I monitor? Obviously HTTP, FTP, POP3 and MySQL, but anything else? Do these services monitor the server load also?
Also, is it a good idea to display these stats publicly?
