This may be kind of a stupid question, but here goes:
Say I'm running a FreeBSD webserver (w/apache). I've managed to close ALL open ports (including SSH/telnet and portmapper), excepting '80' that apache is listening on. A netstat -a shows me nothing open.

Could someone please settle an inter-office argument? Will your network traffic be slower through a firewall on any other port other than port 80. In other words, is port 80 faster than any other port you open on the firewall. I say no. Thanks in advance for the help! (2 Replies)

cports
cports(1M) System Administration Commands cports(1M)NAME
cports - expand host names into <host, server, port> triples
SYNOPSIS
$CLUSTER_HOME/bin/cports hostname [hostname...]
DESCRIPTION
The cports utility expands the hostname arguments into a list of <host, server, port> triples. The returned information is used to access
the serial port consoles of the named hosts by way of the terminal server returned in the triples.
If an entry for serialports has been made in the /etc/nisswitch.conf file, then the order of lookups is controlled by that entry. If there
is no such file or no such entry, then the nameservice look up order is implicitly nis files.
EXAMPLES
Example 1 Using the cports Command
If the /etc/serialports file contains the entry:
pepsi soda-tc 5002
the following command:
% cports pepsi
prints the following string:
pepsi soda-tc 5002
This information can be used by the telnet(1) command to remotely access pepsi's console:
% telnet soda-tc 5002
