I'm still trying to write that seemingly simple Python script to print
out network interfaces (as found in the "ifconfig -a" command) and
their speed ("ethtool <interface>"). The idea is to loop for each
interface and
print out its speed. I'm looping correctly, but have some issues
parsing the output for all interfaces except for the "pan0"
interface. I'm running on eth1, and the "ifconfig -a" command also
shows an eth0, and of course lo. My script is trying to match on the
string "Speed", but I never seem to successfully enter the "if"
clause.
First, here is the output of "ethtool eth1":
=================
Settings for eth1:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Advertised pause frame use: No
Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 1
Transceiver: internal
Auto-negotiation: on
MDI-X: off
Supports Wake-on: pumbag
Wake-on: g
Current message level: 0x00000001 (1)
Link detected: yes
=================
The script *should* match on the string "Speed" and then assign "100Mb/
s" to a variable, but is never getting past the second if statement
below:
=================
#!/usr/bin/python
# Quick and dirty script to print out available interfaces and their
speed
# Initializations
output = " Interface: %s Speed: %s"
noinfo = "(Speed Unknown)"
speed = noinfo
import os, socket, types, subprocess
fp = os.popen("ifconfig -a")
dat=fp.read()
dat=dat.split('\n')
for line in dat:
if line[10:20] == "Link encap":
interface=line[:9]
cmd = "ethtool " + interface
gp = os.popen(cmd)
fat=gp.read()
fat=fat.split('\n')
for line in fat:
if line[0:6] == "Speed":
try:
speed=line[8:]
except:
speed=noinfo
print output % (interface, speed)
=================
Again, I appreciate everyone's patience, as I'm obviously I'm a python
newbie. Thanks in advance!
