Command Kill Zombies

Kill Command Options

Nov 11, 2008

I want to know what does kill -6 PID does?

Is there anything else like kill -1,-2 (expect 9).

Also, what is the diff between kill and kill -9?

How To Kill Apache

Apr 19, 2009

This morning apache stopped to serve pages. I have tried to restart it
with no success:
-------
init.d/httpd restart
----------
init.d/httpd stop
killall httpd
init.d/httpd start
------
killall httpd
init.d/httpd restart
---------

such like several times
every time failed with the
address already in use message

Was 4 oclock in the morning su I stopped investigating and restarted the machine

Is there a way to really shut down such a completely non-responsive process withou restarting the machine?

just a notice - there were not a heavy server load at the time

------------------

Server Version: Apache/2.2.6 (Mandriva Linux/PREFORK-8.2mdv2008.0) mod_ssl/2.2.6 OpenSSL/0.9.8e PHP/5.2.4 with Suhosin-Patch

Kill SSH Tunnel

Jun 26, 2008

I'm doing the following to create an SSH tunnel:

Code:
ssh -fNg -L 8888:127.0.0.1:3306 user@123.456.789.0
How can sort of "undo" that? I ask because I need to re-tunnel in to a different IP address but right now the only way I can figure to do it is to restart my computer (which is lame).

Trying To Kill My Bandwidth

Jan 26, 2007

One of my sites, hosts mp3s for music I've written for video games etc.

I uploaded a track in December, and this month my bandwith has rocketed from 18g to 25g.

When I look at the awstats I see this...

a.a.a.a11811181146.82 MB26 Jan 2007 - 17:47
a.a.a.a+11161116198.40 MB26 Jan 2007 - 17:49
b.b.b.b1151115119.61 KB26 Jan 2007 - 08:00
c.c.c.c62062023.71 MB26 Jan 2007 - 15:18
d.d.d.d543543025 Jan 2007 - 20:52
e.e.e.e537537025 Jan 2007 - 20:18
f.f.f.f 3103104.18 MB26 Jan 2007 - 17:00

Now I'm not sure about the MB values, they don't look true at all, but why suddenly would the two top places have the same IP address bar a value of 1

If I scroll down to file usage, I see

/blah/blah/blah.mp3
7533305.76 KB52685276 - so it's been viewed 7533 times

and the next most popular page or file is,
/
10099.69 KB830412

Then looking at the search engine stats the most popular search engine phrase is this
[url][summer dance]45041.2 %

450 times? and yes, - np2sp6qjpj2jkzevo5mcl2fjmw$$.mp3 [summer dance] - this is the filename coming up even though it doesn't exist on the server

It's twice as popular as "game sounds" which is the site, and is on google... something fishy going on here.

The most popular site to come from is [url] times in fact, and that's a japanese/chinese/eastern site which I don't understand.

The IP address appears to be chinese too.

Can anyone explain to me what might be going on here please? It appears that someone is continuously downloading this specific file, just to use up my bandwidth?

Find And Kill Spammers!

May 18, 2007

Just got alerted that my server is being used to send spam. Here is the information the datacenter gave me:

[information .....]

NOTE: I changed the real domain name and IP only.

Is there an expert who can help me decipher this? How do I find the culprit? My provider is threatening to shut me down and sink all my clients with the ship!

I am running the latest WHM and cpanel server, fyi.

We Kill Servers :: Cloud/cluster

Apr 10, 2008

Our website is based around a customer based chat system. Customers are only on the system during a particular day and time range. So for parts of the week the server gets almost no traffic. When then time for a chat comes up we get hundreds of people on the site all doing page requests every few seconds.

So as you might imagine we are bringing the server to it's knees with heavy CPU and memory loads. Plus bandwidth usage is really high. We are currently on the biggest box that Rackspace has to offer. The site runs ok on it during these times. It's a little slow but not unbearable.

But we have not hit our max customer base. In fact if all goes well we will double our customer base next month. So I know when we do we will bring that box down totally.

I was thinking about possibly trying a cloud/cluster based approach but after some research on this site I have found that is probably not the best option.

So I am looking for advice on what to do? Is there a better host? Different technology?

Servers are not my thing really so I could really use some help.

No we can't change the way customers access the site or when they access. There is nothing that can be done in that regard so don't suggest it.

DDOS Attack Kill Only Apache Server

Jan 11, 2007

I have a question related DDOS attack. My hosting provider told me that my Server was DDos attacked few days ago. But in those days my server worked fine only apache server was down. The strange fact is that in the same day with this "DDOS attack" one of theyr admins worked something on SSL section of my server and during this operation the SSL hosts were down and httpd worked slow.

Inthe passed 3 months httpd worked very slow and after 2-3 restarts of httpd service the load droped down below 3.00 . I believe theyr httpd service was already with problems and that SSL configuration cause that apache failure in that day with "ddos attack"

I repeat in that day ONLY ssl hosts worked fine and non SSL hosts were down.

It's possibile on DDOS attack that load to be unde 0.5 , SSL hosts to work fine, FTP, Mail and other stuf to work like there is nobody on server (VERY FAST)?
