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.
