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)

rxtelnet
RXTELNET(1) BSD General Commands Manual RXTELNET(1)NAME
rxtelnet -- start a telnet and forward X-connections.
SYNOPSIS
rxtelnet [-l username] [-k] [-t telnet_args] [-x xterm_args] [-K kx_args] [-w term_emulator] [-b telnet_program] [-n] [-v] host [port]
DESCRIPTION
The rxtelnet program starts an xterm window with a telnet to host host. From this window you will also be able to run X clients that will be
able to connect securely to your X server. If port is given, that port will be used instead of the default.
If setting up the X forwarding failes, rxtelnet will still telnet in to the remote host, but without X forwarding.
The supported options are:
-l Log in on the remote host as user username.
-k Disables keep-alives.
-t Send telnet_args as arguments to telnet.
-x Send xterm_args as arguments to xterm.
-X Send kx_args as arguments to kx.
-w Use term_emulator instead of xterm.
-b Use telnet_program instead of telnet.
-n Do not start any terminal emulator.
-v Be verbose.
EXAMPLE
To login from host foo (where your display is) to host bar, you might do the following.
1. On foo: rxtelnet bar
2. You will get a new window with a telnet to bar. In this window you will be able to start X clients.
