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
Do you know Nobody Check Security Tool? Do you recommend it?

View 5 Replies View RelatedIf you have CSF installed, under its WHM section there is a quick security 'scan' you can run - just wondering what score you have?
I know it's not an infallible test, but the scan does test for some potentially large weaknesses hence why I'm asking here (mainly out of curiosity) what sort of scores people have.
Mine is 103/112 - the rest of the points were mainly for features I didn't want enabled for particular reasons (i.e. one of the recommendations is to force all cPanel visits to be through SSL, a feature which some clients don't want) plus sometimes it says I've got features enabled which are disabled, etc.
I run a web hosting company and one of my servers is a LAMP server running CentOs 5. A user of mine has a Joomla installation running to manage his website and he has run into the following problem that I am puzzled by.
When Joomla adds a component or module to itself, or when a user uses the Joomla upload functionality, Joomla will add the new files under the user name "apache". This makes sense as it is the apache service running PHP that is actually creating the files.
However, when he FTP's into the account to modify these files, he doesn't have the appropriate permissions to do so as he doesn't have a root level login, just permissions on his home directory which is the site. Any help would be much appreciated.
Also, does anyone know how to change the owner/group of a directory and all of its sub directories in Linux without changing the actual permissions? I.e. some of the files in the folder have different permissions (0644 as apposed to 0755) than its parent but if I do a top down user/group change on the folder it will change everything in that folder to 0755.
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 recently purchased a VPS from internetvps.com, but im not sure what OS of linux it is. How can you check the OS of the server?

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.

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.

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

[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!
i just don't remember what was the command to check logfile in linux to see what was going on in my server, since i think someone hacked in to my server and i was ddos last couple days.
