I wrote a script that shows you in a condensed way if you’re in network card speed trouble:
\n# ——————— server app213
\nbond0= eth1 eth2
\nbond0 : : : : : 10.20.9.38
\neth0 : 100Mb\/s : Half : on : yes : 192.168.5.119
\neth1 : 100Mb\/s : Half : on : yes :
\neth2 : 100Mb\/s : Half : on : yes :
\neth3 : Unknown! (65535) : Unknown! (255) : on : no :
\nHere it goes:
\n#!\/bin\/bash
\nDIR=\/tmp\/.dir
\nmkdir $DIR > \/dev\/null 2>&1
\nHB=`ifconfig -a | grep -i bond | wc -l | sed ‘s\/ \/\/g’`
\nif [ “$HB” -ne “0” ];then
\nfor i in `ifconfig -a | cut -c0-10 | egrep -i ‘bond’| grep -v ‘:’`;do
\necho -n “$i=”
\nfor i in `cat \/etc\/sysconfig\/network\/ifcfg-$i | grep “BONDING_SLAVE” | awk -F”=” ‘{ print $2 }’ | awk -F”‘” ‘{
\nprint $2 }’`;do
\necho -n ” $i”
\ndone
\necho “”
\ndone
\nfi
\nfor i in `ifconfig -a | cut -c0-10 | egrep -i ‘bond|eth’| grep -v ‘:’`;do
\nSP=`ethtool $i | grep “Speed:” | awk -F: ‘{ print $2 }’`
\nDU=`ethtool $i | grep “Duplex:” | awk -F: ‘{ print $2 }’`
\nAU=`ethtool $i |grep “Auto-negotiation:” | awk -F: ‘{ print $2 }’`
\nLI=`ethtool $i | grep “Link detected: ” | awk -F: ‘{ print $2 }’`
\n(for w in `ifconfig $i`;do
\necho “$w”
\ndone) | grep “addr:” | awk -F”:” ‘{ print $2 }’ > $DIR\/addr
\necho “$i : $SP : $DU : $AU : $LI : `cat $DIR\/addr` ”
\ndone
\nset network card speed by default in redhat.
\nIf your interface is eth0, in the etc\/sysconfig\/network-scripts folder, vi the ifcfg-eth0 script. add the parameters
\nETHTOOL_OPTS=”speed 100 duplex full autoneg on”, and you’re set
\nNext time the server reboots you have the right speed set
