    I found a security site that recommends the following for the /etc/services file. The following are the only ports that are open, I presume.

    tcpmux 1/tcp
    echo 7/tcp
    echo 7/udp
    ftp-data 20/tcp
    ftp 21/tcp
    ssh 22/tcp
    smtp 25/tcp mail
    domain 53/tcp
    domain 53/udp
    http 80/tcp www www-http
    pop3 110/tcp pop-3
    imap 143/tcp imap2
    https 443/tcp
    smtps 465/tcp
    syslog 514/udp
    imaps 993/tcp
    pop3s 995/tcp
    rndc 953/tcp
    rndc 953/udp
    mysql 3306/tcp

    Then I noticed that the CPanel ports are not lised there
    2082
    2083
    2087
    2086

    Hmmmm. Then I checked the current /etc/services file that was installed with CPanel and it also does not have the CPanel ports listed.

    So, color me confused. Will the suggested /etc/services list above assist me in making my server more secure without harming CPanel?

    Oh, and for those that are thinking about flaming me, yes, I have searched the forum for Ports "Open Ports" etc. and did find a helpful thread http://forums.cpanel.net/showthread.php?s=&threadid=13834&highlight=ports . My question is simply will the suggestions from the list that I have above secure a Cpanel server without harming CPanel. If there is a problem with the list, then I would like to point this out to the author of the list who suggested it is a CPanel ports list good for Cpanel.
