How To Check Ram
Jun 7, 2007
Let's say I have a VPS with 512 MBs of RAM.
How do I check in shell that this is indeed the case?
I read in some places that "top" and "free -m" and such can help.
But these gave me way more than 512.
Here is the output from my "free -m". Total shows here 3886 MBs of MEM??? That is almost 4 Gigs. Please someone explain this.
total used free shared buffers cached
Mem: 3886 3721 164 0 17 542
-/+ buffers/cache: 3161 724
Swap: 6142 2020 4121

I would like to know how to check load via ssh and check files causing load?
I want the ssh codes for 2 different set of control panels, one with cpanel+whm and other with kloxo+hypervm
and I would also know how to check the files causing the load, such as some files could have been interrupted while processing, so they could be causing load some times, so I want to stop such processes if any are running on the vps on my friends accounts

I'm running CSF on a Cpanel server and have questions about new features in CSF
Apache Check
Check Apache weak SSL/TLS Ciphers (SSLCipherSuite)
Results
Cipher list []. Due to weaknesses in the SSLv2 cipher you should disable SSLv2 in WHM > Apache Configuration > Global Configuration > SSLCipherSuite > Add -SSLv2 to SSLCipherSuite and/or remove +SSLv2. Do not forget to Save AND then Rebuild Configuration and Restart Apache, otherwise the changes will not take effect in httpd.conf
Can someone explain this in laymen terms? I know this is new in Cpanel. I'm already running Apache 2.2, PHP 5.2.9 with suPHP enabled and mod_security as well (these rules: [url]
Also, what exactly are these CSF checks?
Check csf PT_SKIP_HTTP option
This option disables checking of processes running under apache and can limit false-positives but may then miss running exploits
Check csf SAFECHAINUPDATE option
This option closes a window of opportunity that opens when dynamic chain updates occur

Now, via command line how can I check that ALL these work and are enabled for example? I'm not talking about visually seeing the files there, I mean actually enabled.

I recently added ubl.unsubscore.com to my email server. I only have that one and the SpamHaus (Zen) activated.
I am able to see the SpamHaus listed on DNSStuff and on SpamHaus website that the person trying to email me is not listed.
So I have to think that it is ubl.unsubscore.com list. But what domain name can I enter into the browser to check this list? www.unsubscore.com does not work. A little searching led me to lashback, but the IP is not listed there either.

Few days ago I had a problem with my httpd. I finally nailed it down and came on a conclusion that my MaxClients were set too low so I had to set it to high number and it seems like that the proble of "Network Timeout" had been resolved but now the problem is still continued. Here is what I think is wrong
Cpu(s): 1.5%us, 0.4%sy, 0.0%ni, 96.7%id, 0.3%wa, 0.3%hi, 0.8%si, 0.0%st
The 96.7%id always stays above 90% is that bad and how do i fix it?

I have a problem where mysqld is using 95 - 97% CPU usage all the time.
How can I see what user is causing this ? I have installed mytop but when I use it I get
Quote:
[root@server1 ~]# mytop
Cannot connect to MySQL server. Please check the:
* database you specified "test" (default is "test")
* username you specified "root" (default is "root")
* password you specified "" (default is "")
* hostname you specified "localhost" (default is "localhost")
* port you specified "3306" (default is 3306)
* socket you specified "" (default is "")
The options my be specified on the command-line or in a ~/.mytop
config file. See the manual (perldoc mytop) for details.
Here's the exact error from DBI. It might help you debug:
Access denied for user 'root'@'localhost' (using password: NO)
I really need to track down the culprit!

Am am running through a checklist of to-do's on a new VPS I just received. I haven't used it in a production environment yet.
While doing a root kit check I got these lines back that perturb me.
Checking `bindshell'... INFECTED (PORTS: 465)
Checking `lkm'... You have 103 process hidden for readdir command
chkproc: Warning: Possible LKM Trojan installed
how serious the implications are of those lines? And should I expect this on a machine that has no traffic and is a fresh install?

One of my hosted user complained that he can't access his website nor he can ping the website. When I asked him to access my 2nd server (same datacenter), it went fine. I could be thinking that my server is blocking his IP.
How do I check if his IP is blocked?
I am using APF+BFD Iptables firewall (i don't know but i hope this make sense)

I'm asking because in HyperVM, I can see the max ram for the 2 packages as 2GB. how to check the guaranteed ram?
Also both of these are quad core but the other is showing 2.7Ghz per cpu while the other it's 0.5GHz.
