小弟刚步入linux系统没多久而已,目前遇到一个问题 我想在macbook上使用speedometer这个网路监测软体,想说都是以unix下去发展出来的OS, 执行上照理说可行的，但目前遇到下面问题 speedometer -rx eth0 时显示以下 Traceback (most recent call last): File "/usr/local/bin/speedometer", line 1093, in <module> console() File "/usr/local/bin/speedometer", line 797, in console wait_all(cols) File "/usr/local/bin/speedometer", line 1088, in wait_all tap.wait_creation() File "/usr/local/bin/speedometer", line 856, in wait_creation if self.feed() is None: File "/usr/local/bin/speedometer", line 610, in networkfn f = open('/proc/net/dev') IOError: [Errno 2] No such file or directory: '/proc/net/dev' 如果输入 speedometer -rx Usage: speedometer [options] tap [[-c] tap]... Monitor network traffic or speed/progress of a file transfer. At least one tap must be entered. -c starts a new column, otherwise taps are piled vertically. Taps: -f filename [size] display download speed [with progress bar] -r network-interface display bytes received on network-interface -t network-interface display bytes transmitted on network-interface -c start a new column for following tap arguments Options: -b use old blocky display instead of smoothed display even when UTF-8 encoding is detected (use this if you see strange characters) -i interval-in-seconds eg. "5" or "0.25" default: "1" -k (1|16|88|256) set the number of colors this terminal supports (default 16) -l use linear charts instead of logarithmic you will VERY LIKELY want to set -m as well -m chart-maximum set the maximum bytes/second displayed on the chart (default 2^32) -n chart-minimum set the minimum bytes/second displayed on the chart (default 32) -p use original plain-text display (one tap only) -s use bits/s instead of bytes/s -x exit when files reach their expected size -z report zero size on files that don't exist instead of waiting for them to be created Note: -rx and -tx are accepted as aliases for -r and -t for compatibility with earlier releases of speedometer. -f may be also omitted for similar reasons. Speedometer requires Urwid 0.9.9.1 or later when not using plain-text display. Urwid may be downloaded from: http://excess.org/urwid/ Urwid may be installed system-wide or in the same directory as speedometer. Python Version: 2.7 Urwid >= 0.9.9.1 detected: NO UTF-8 encoding detected: NO 如果输入 speedometer eth0 Waiting for 'eth0' to be created... 然後就卡在这边了 上述都有google过了,好像有网友建议前面给个sudo,但还是没用... 在此感谢 --
