I have a customer with a 6GB cpanel account that I have had to restore a few times recently. Both times, the server nearly crashed, as the load approached 120! On the 3rd restore, I finally figured out what the problem... it was cxs scanning all the files being restored!

To solve the problem I did the following:

Went to Service Monitor in WHM and temporarily disabled monitoring of cxswatch....

I just need to put some files in the cxs.ignore file but I'm a noob at regexp so please, help me build the specific regexp for the following:

a. Needed pfile: regexp#1: (specific filename WITH specific extension, REGARDLESS of path)
/untgz.php

b. Needed pfile: regexp#2: (specific filename, REGARDLESS of extension, REGARDLESS of path)
/thisismyfile.*​

For the past hour I have been flooded with tens of such emails from cxs. In the email it refers to a non existing file on the server,(I believe a bot is searching for exploitable scripts on the domain.) as the upload path ( each different path on each email) and the file does not exist. however cxs states that the file has been quarantined. How is this possible if the hacker cannot upload any...

Hi,

We've been running into this issue for at least the last year now, and it appears the old post regarding this issue has disappeared, so I figured we would bring it back to your attention.

We run cPanel on all of our servers, we have CXS on about 10-15 of them. Sometimes pure-ftpd will randomly stop functioning for no apparent reason. The process will be running, but trying to connect will...

For some reason I'm constantly getting hit hard from obsmtp dot com which is a Google IP address. One of the matching IP addresses is 68.18.3.39. I want to completely block anything from 64.18.0.0 and on. Would the correct way to input that into my deny config file be like this?

68.18.0.0/32

Update:
I think I was able to get it.
68.18.0.0/16 I believe blocks all from 68.18.*.*

Got an odd problem on the last server you guys set up.

The cxs daily cron will sometimes just hang and prevent the logrotate process from running. I'll notice it when I receive an email that /var is running out of drive space, due to logs growing in size.

If I kill the cxs cron, then logrotate will run. I've noticed this happening about 3 or 4 different times since last december. Just noticed...

I am using cxs v 4.14. I am editing the cxs Watch configuration via the WHM plug-in, under Configure cxs Watch

In that file, it shows my options as: --options mMOLfSGchednWDZR

After saving, I am clicking Restart cxs Watch .

When I receive a cxs Scan alert email, it shows in the SCAN REPORT my options as: --options mMOLfSGchexdnwZDRu

As you can see, they do not match.

What am I doing wrong?...

Hi Jonathan,
yesterday a hacker managed to ftp to a compromised password on a customer and uploaded a few modified files that he downloaded previously.

All the files are java scripts with the extension .JS, I have checked the code and added the code to the xtra file, using REGALL but CXS is not checking the .js files and the files are not quarantined.

What is the best approach to check .js...

I keep getting this error.

WARNING: Quarantine disabled - Directory has incorrect permissions , run cxs --qcreate --quarantine /home/quarantine

I have moved the old quarantine directory elsewhere and ran cxs --qcreate --quarantine /home/quarantine but continue to get the error. I have also just tried chmod 0755 on the quarantine directory to no avail.

Any suggestions?

Thanks,
Eric

The last few days we notice that email reports from cxs if reporting a virus now say:
WARNING: Quarantine disabled - Directory missing, run cxs --qcreate --quarantine
WARNING: Quarantine disabled - Directory missing, run cxs --qcreate --quarantine

Hi,

To lower load for a webhost is running the cron job necessary.

Basically I was thinking:

1. Run CXS cronjob once a week
2. Have CXSWatch run all the time.

IS this good enough? Opinions

Hello,

I just done the cxs v4.04 update and it broke the Documentation info.

Usage: perldoc PageName|ModuleName|ProgramName Examples: perldoc -f PerlFunc perldoc -q FAQKeywords perldoc -v PerlVar The -h option prints more help. Also try perldoc perldoc to get acquainted with the system.

this is what it shows now.

Hello,

CXS is using over 50% of my dedicated server's CPU. is there a setting to limit it's CPU or resource usage? If not, what third party solution do you recommend? I am happy for this scan to take a lot longer as long as the CPU usage does not go above 20%.
Thanks,

NOTE: Support for using suhosin is deprecated and will be removed in
the near future - use ModSecurity instead. If you are unable to use
ModSecurity, you will have to rely on either cxs Watch or manual scans

Does this only apply to scanning of PHP Upload scripts?

What I mean is: I use CXS Watch, and I also use Suhosin. Will CXS Watch stop working for PHP if I keep using Suhosin (in the...

New option added: --defapache . This is the default account
under which apache runs. This will be set to apache by default
except on cPanel servers where it is set to nobody by default

I have a cPanel server. So it is set to nobody by default.

Is there a more secure value rather than nobody or is that value required (and secure as-is)?

I don't fully understand what nobody means and any...

This morning in my logs I noticed the following messages being repeated over and over with random usernames. Any idea what causes this and is it something I should be concerned about?
