Firewall Ports

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(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. SEE ALSO
