Subject: using matasano's blackbag/deezee to find 0day and
	stuff

remote un-passworded root access in IBM's totalstorage ds400 storage
thingie, like this:
# download deezee from http://www.matasano.com/tools/deezee.tar.gz
# download firmware for totalstorage ds400
lort# wget -q http://parker.vslib.cz/MIRRORS/ftp.adaptec.com/tmp0001/oem/ibm/IBM_TotalStorage_DS_Series_FW_v4.15.zip
lort# unzip -q IBM_TotalStorage_DS_Series_FW_v4.15.zip
lort# rm IBM_TotalStorage_DS_Series_FW_v4.15.zip
lort# ls

# The inetd will re-read this file whenever it gets that signal.

# <service_name> <sock_type> <proto> <flags> <user> <server_path> <args>

# If you want telnetd not to "keep-alives" (e.g. if it runs over a ISDN
# uplink), add "-n".  See 'man telnetd' for more deatails.

# sit back and laugh at the passwordless accounts and the undocumented
