ether(1L)

NAME
ether - Display a strip chart of network traffic.

SYNOPSIS
ether [ -c<color_map_indexes> ] [ -f<freq> ] [ -m<max> ]

DESCRIPTION
Ether is a graphical version of netstat that runs on mgr terminals. Ether, displays the number of input packet, output packets, and collisions on the first network interface reported by netstat.

The following options are recognized on the command line:

-f<freq>
    The display is updated every freq seconds, instead of the default 3 seconds.

-m<max>
    specifies the maximum number of packets counted per update. The default is 15.

-c  If ether is run on a color version of MGR, various parts of the display are shown in different colors. This option alters the colormap index values used. The -c is immediately followed by a string of characters in the range of [0-9a-z] where each color represents a colormap index from 0 to 36 respectively. The position in the string determines what portion of the display is affected as follows:

    #	use

    0	unused
    1	background
    2	title
    3	axis labels
    4	grid lines
    5	values that exeed the maximum
    6	color for plots

DIAGNOSTICS

Window is not wide enough
    Make the window wider and the graph will continue.

Window is not high enough
    Make the window taller and the graph will continue.

BUGS
If the window is reshaped, ether requires up to freq (usually 3) seconds to learn about the new window size.

Ether calls netstat(1) and assumes a particular output format from it (i.e. 4.2 BSD).
