Dropping packets problem

[oceandeep]

My linux machine is having some problems recently. It is running RedHat 6.2. Everytime I booted it up, I saw a lot of messages showing that 'dropping the pack xxxxx'. And after it booted up, the same messages might be displayed showed sometimes as well. It was running very well previously. I really have no idea where to troubleshoot it.
Could anybody here give me the enlightment?
Thanks a lot in advance.

Umm, pardon my ignorance but from what your title and description imply your server is trying to send packets to someplace on boot? if you can get us the exact error message it would help everyone to troubleshoot the issue easier. To do this, type as root: cat /var/log/boot.log and paste us the lines that say "Dropping pack XXXX" without adding too much of the other stuff, i believe that right now everyone is curious as to what the exact error message is that you are getting, and not so much concerned with your h/w s/w packages.I hope this helps.

Thank you for your reply. Unfortunately, I couldn't find any lines in boot.log file contain the information about 'dropping packet', even though it really happened at that stage. And even when I was using vi to view the boot.log file, the same problem may also happen. So it looks like sort of debug info displayed on the console.
And the actual message displayed is like:
dropiing the packet 6004
dropiing the packet 6004
dropiing the packet 5f04
dropiing the packet 6004
dropiing the packet 6004
dropiing the packet 5f04
dropiing the packet 5f04
...
...
just the last number may veriy. And the spelling of 'dropping' is also quite strange...
Please let me know if you need additional information. Thanks a lot!

That is extremely wierd, Can you post what is in your /etc/rc.d/rc.local file. I'm trying to see if anything is setup in that dir to send packets on bootup.

# cat rc.local

#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

if [ -f /etc/redhat-release ]; then
R=$(cat /etc/redhat-release)

arch=$(uname -m)
a="a"
case "_$arch" in
_a*) a="an";;
_i*) a="an";;
esac

NUMPROC=`egrep -c "^cpu[0-9]+" /proc/stat`
if [ "$NUMPROC" -gt "1" ]; then
SMP="$NUMPROC-processor "
if [ "$NUMPROC" = "8" -o "$NUMPROC" = "11" ]; then
a="an"
else
a="a"
fi
fi

# This will overwrite /etc/issue at every boot. So, make any changes you
# want to make to /etc/issue here or you will lose them when you reboot.
echo "" > /etc/issue
echo "$R" >> /etc/issue
echo "Kernel $(uname -r) on $a $SMP$(uname -m)" >> /etc/issue

cp -f /etc/issue /etc/issue.net
echo >> /etc/issue
fi

Thank you very much, friend!
