Hello, I am using rlinetd as replacement for inetd on a firewall. With rlinetd you can deceide which inetd services are allowed to be available for the inside and which for the outside world. When I do a nmap localhost, echo, discard, daytime, chargen, ftp, telnet, smtp and time are available (and ssh as daemon). When I do a nmap from the internet, only ssh is available.
Now my question: how secure is this daemon, i.e. is it virtually impossible to penetrate this daemon from the outside world? Is it a good idea to run rlinetd on a firewall? I want to keep telnet, smtp and ftp available for my lan. Thanks in advance, Sebastiaan
