WARNING: MaxClients of 1000 exceeds ServerLimit value of 256 servers,
lowering MaxClients to 256. To increase, please see the ServerLimit directive.… Read More

Sadly, in my tiredness and googleing I didn’t immediately find the answer until today shortly after I woke up, I finally found the solution here. In short “ServerLimit” MUST MUST gobefore MaxClients otherwise this error will show up, no matter how many times you check that you spelled everything right, and how many times you restart the service!

ServerLimit             1000
MaxClients              1000

Simple fix, but if you don’t know, it can be quite a headache!

root@sat1 [/usr/local/apache/domlogs/ommited]# cat ommitedsite.com | awk ‘{print $1}’ | cut -d: -f1 | sort | uniq -c | sort -n
root@sat1 [/usr/local/apache/domlogs/ommited]#

Basically says how many times the ip has hit your site:

182 81.82.240.15
192 202.28.180.202
203 188.220.62.52
204 41.223.251.18
225 81.27.128.142
228 124.157.129.20

Looks good in terminal, usually I use it for checking if a box of mine is getting flooded or if theres simply getting too much traffic. That command looks like this:

netstat -ntu | awk ‘{print $5}’ | cut -d: -f1 | sort | uniq -c | sort -n

Obviously if your getting too much and want to analyse the outpout in a text file, append > output.txt, and use vi, or nano to look into it.

netstat -ntu | awk ‘{print $5}’ | cut -d: -f1 | sort | uniq -c | sort -n > output.txt

Hope this helps some of you.

WHM -> Server Configuration -> Tweak Settings and checking Disable whois lookups for the nameserver IP manager

My server is running: cPanel 11.24.5-R38506 – WHM 11.24.2 – X 3.9, CENTOS 5.3 i686 virtuozzo.

The fix.

Basically

rm -rf /usr/bin/rar
ln -s /usr/local/rar/rar_static /usr/bin/rar

For me the location varied a little because I extracted everything in a different spot!

Some of you may find this to be pretty elementary, but lets see what I can come up with in the next day or two. Essentially all this does is looks for a country that matches the code you put in. It does not include all countries, but I think I got the idea of elsif in perl.

r00t@r00t-laptop:~$ sudo apt-get install openssh-server
Reading package lists… Done
Building dependency tree
Reading state information… Done
Package openssh-server is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package openssh-server has no installation candidate

No big deal, lets look up how to fix this online.

After a whole 2 minutes of googling I figure out all I need to run are:

sudo apt-get update

sudo apt-get install ssh-server

Done. Now fire up putty and try to connect or “ssh -p 22 localhost”.
