Ethtool script not running on boot.
Hi, there is an incompatibility between my NIC and my Western Digital Powerline adapters which appears to cause autonegotiation to fail intermittently, most often following a reboot. Running the following Ethtool script will establish a connection immediately:
#!/bin/sh
# chkconfig: 345 85 15
ETHTOOL="/usr/sbin/ethtool"
DEV="eth0"
SPEED="100 duplex full"
case "$1" in
start)
echo -n "Setting eth0 speed 100 duplex full...";
$ETHTOOL -s $DEV speed $SPEED;
echo " done.";;
stop)
;;
esac
exit 0
I have tried placing this script in /etc/init.d, and it is shown as a selected option when running ntsysv but to no avail.
The recommended method for Fedora is to add ETHTOOL_OPTS="speed 100 duplex full autoneg off" to /etc/sysconfig/network-scripts/ifcfg-NameOfConnection which again is not working.
I'm running Fedora 15 64-bit, NIC = Intel 82562V-2 10/100.
If anyone is able to help out then they would probably save my hair from being wrenched out. Thanks

truncate
TRUNCATE(1) User Commands TRUNCATE(1)
NAME
truncate - shrink or extend the size of a file to the specifed size
SYNOPSIS
truncate OPTION... FILE...
DESCRIPTION
Shrink or extend the size of each FILE to the specified size
A FILE argument that does not exist is created.
If a FILE is larger than the specified size, the extra data is lost. If a FILE is shorter, it is extended and the extended part (hole)
reads as zero bytes.
Mandatory arguments to long options are mandatory for short options too.
-c, --no-create
do not create any files
-o, --io-blocks
Treat SIZE as number of IO blocks instead of bytes
-r, --reference=FILE
use this FILE's size
-s, --size=SIZE
use this SIZE
--help display this help and exit
--version
output version information and exit
SIZE is a number which may be followed by one of the following suffixes: KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P,
E, Z, Y.
SIZE may also be prefixed by one of the following modifying characters: `+' extend by, `-' reduce by, `<' at most, `>' at least, `/' round
down to multiple of, `%' round up to multiple of.
Note that the -r and -s options are mutually exclusive.
