# Thx to xuso for help me with the shellcode.
#
# I suppose that you've the "RewriteRule kung/(.*) $1" rule if not
# you must recalculate adressess.
#
# Shellcode is based on Taeho Oh bindshell on port 30464 and modified
# for avoiding apache url-escape.. Take a look is quite nice ;)
#
# Shellcode address in heap memory on apache 1.3.34 (debian sarge) is at
# 0x0834ae77 for any other version/system find it.
#
# Gulcas rulez :P

Поясните, как подбирать адреса под что-то иное, нежели "RewriteRule kung/(.*) $1" и под что-то не "apache 1.3.34 (debian sarge)" ? Чисто технически как?
