squid delay pool ลองสรุปดู
โจทย์
ต้องการ delay pools เวปพวก file sharing เช่น mediafire, rapid, 4shared
คำตอบ...
สร้าง pattern format มาก่อนเลย
acl compress urlpath_regex -i .3gp .7z .ra[mrw] .zip
# สร้าง pattern ชื่อ compress โดยมีนามสกุลที่สนใจคือ
*.3gp, *.7z *.ram *.rar *.raw *.zip
ประกาศใช้งานบีบบบบ ตาม pattern ที่เรากำหนด
delay_pools 1 #<< มี delay pools อันเดียวนะ... เติม s ทำไมเนอะ
delay_class 1 3 #<< pool 1 เป็น class 3
delay_parameters 1 2000000(2Mbps)/2000000(2M) -1/-1 120000(120k)/8000000(8M)
delay_access 1 allow compress
delay_access 1 deny all
# class 3 Everything is limited by a single aggregate
# bucket as well as a "network" bucket chosen
# from bits 17 through 24 of the IP address and
# a "individual" bucket chosen from bits 17 through
# 32 of the IP address.
โดยในตัวอย่างจะมี
#Example:
# delay_pools 4 # 4 delay pools
# delay_class 1 2 # pool 1 is a class 2 pool
# delay_class 2 3 # pool 2 is a class 3 pool
# delay_class 3 4 # pool 3 is a class 4 pool
# delay_class 4 5 # pool 4 is a class 5 pool
และคำอธิบาย class จะมีดังนี้
# The delay pool classes are:
#
# class 1 Everything is limited by a single aggregate
# bucket.
#
# class 2 Everything is limited by a single aggregate
# bucket as well as an "individual" bucket chosen
# from bits 25 through 32 of the IP address.
#
# class 3 Everything is limited by a single aggregate
# bucket as well as a "network" bucket chosen
# from bits 17 through 24 of the IP address and
# a "individual" bucket chosen from bits 17 through
# 32 of the IP address.
#
# class 4 Everything in a class 3 delay pool, with an
# additional limit on a per user basis. This
# only takes effect if the username is established
# in advance - by forcing authentication in your
# http_access rules.
#
# class 5 Requests are grouped according their tag
# (see external_acl's tag= reply).
#
# NOTE: If an IP address is a.b.c.d
# -> bits 25 through 32 are "d"
# -> bits 17 through 24 are "c"
# -> bits 17 through 32 are "c * 256 + d"
