To quote Glenn Becker <[EMAIL PROTECTED]>, # # All, # # I have been trying to secure my Debian box, which enjoys a DSL # connection. I've been going through /etc/inetd.conf, commenting out # services, and K'ing others in the /etc/rc2.d/, until what I have left is # the following (output from nmap): # # Interesting ports on localhost (127.0.0.1): # Port State Protocol Service # 22 open tcp ssh # 25 open tcp smtp # 53 open tcp domain # 111 open tcp sunrpc # # So, the questions: I have read some about sunrpc in the list archives but # have not found how to close the port; don't know what domain is, and am # confused smtp is still there since I've commented out the line in # inetd.conf ... I have set my hosts.deny to # # ALL EXCEPT sshd: ALL # # ... I guess then port 22 is not a concern?
Personally, I've never put a whole lot of faith into just turning services off. Now, I could be wrong. What I usually do is use 'ipchains' to set up a firewall. Not that it helps you here, but it's something to think about :) David Barclay Harris, Clan Barclay Aut agere, aut mori. (Either action, or death.)
