    Hello,

    I have recently migrated to a VPS - its CentOS 6, cPanel and WHM.

    I have additionally installed CSF on the VPS.

    The above configuration was working fine from last 3 months, but last week, I received a notification that CSF was automatically updated (through cPanel or by it own) and after that update (or some other update about which I do not have any idea), a strange problem has started occuring.

    I reboot the VPS and I am unable to access it by any means - the web server (apache) stops, pop3 stops, ftp stops, ssh stops, I completely lose control over it.

    I received notifications from the server, once its gets recovered -

    ***************************
    chkservd attempts to connect to 127.0.0.1:21 in order to validate this service is functioning. If you have blocked connections with iptables or hosts.allow this failure may be a false positive. You should open the firewall to allow connection as root to 127.0.0.1:21 or disable checks of this service in the Service Manager using the Configure monitor settings link below.
    ***************************
    imap failed @ Tue Dec 10 12:49:08 2013. A restart was attempted automagically.
    ***************************
    exim-26,587 failed @ Tue Dec 10 12:04:16 2013. A restart was attempted automagically.

    Running `/usr/local/cpanel/scripts/updatenow --upcp --log=/var/cpanel/updatelogs/update.1386656361.log` failed, exited with code 4 (signal = 0)
    ***************************
    cpsrvd failed @ Tue Dec 10 16:06:11 2013. A restart was attempted automagically.
    ***************************

    Can you help me how to fix this, as the moment I reboot the server, all network services stops working, I am a Windows Guy and Learning how to manage Linux, I am posting here with a hope that someone may have come through this problem and can share his comments with me.

    Is this caused by the CSF update? Should I remove CSF? I am very happy with CSF as it helps me block all the brute force attacks, and dont want to remove this beautiful software.

    Many thanks for the replies and suggestions.

    Rajiv

    Hello :)

    Do you experience this issue if you temporarily disable CSF? Is the issue resolved if you restart the "ipaliases" service? EX:

    Code:
    service ipaliases restart
    Thank you.

    I recommend consulting with CSF support directly on their support forums if the issue is isolated to their software. Their developers may have a workaround or know of the cause of this problem.

    Thank you.
