Howdy Jean-Lewis! I would personally recommend using ssh (scp or sftp) if at all possible for moving your Web pages instead of FTP, as the FTP session is not encrypted.
Just make sure you are using an up-to-date SMTP agent. I don't think Sendmail has had a remote root exploit since 1997, but has had some recent local root exploits. I don't know if identd (113) is actually needed, although I think remote MTAs attempt to query your ident server to find the UNIX user sending mail. It is probably also necessary for IRC. I don't think having it open is very risky. My two cents :) Brandon On Tuesday 20 November 2001 10:06 am, you wrote: > I'm trying to limit the ports open on a Linux box. > > If I reduce the list to : > - SMTP/25 > - ssh/22 > - proftp/21 > - http/80 > - https/443 > - authentication/113 > > Do you think that will work ok? that box is a web server only, with > proftp/ssh session for updating pages. > > Thanks to all. > > Have a nice day. > > Jean-Louis
