Proxy Squid en corel linux

Hola que tal mi amigo sabes casi no he entendido mucho por que me mencionas unos direcciones de direcciones que en corel linux no se encuentran asi pero se encunetran de otra manera y tambien unos comandos como squid restart que hal utilizarlo me dice en el bash comando no encontrado,,, otra cosa segui un paso tuyo y solamente mi maquina servidor le puse el proxy y si funciona pero se lo puse a otra y no funciona que sera este es mi squid.conf
# WELCOME TO SQUID 2
# ------------------
#
# This is the default Squid configuration file. You may wish
# to look at the Squid home page (http://www.squid-cache.org/)
# for the FAQ and other documentation.
#
# The default Squid config file shows what the defaults for
# various options happen to be. If you don't need to change the
# default, you shouldn't uncomment the line. Doing so may cause
# run-time problems. In some cases "none" refers to no default
# setting at all, while in other cases it refers to a valid
# option - the comments for that keyword indicate if this is the
# case.
#
# NETWORK OPTIONS
# -----------------------------------------------------------------------------
# TAG: http_port
# Usage: 3128
# 200.41.100.79:3128
# 200.41.100.79:3128
#
# The socket addresses where Squid will listen for HTTP client
# requests. You may specify multiple socket addresses.
# There are three forms: port alone, hostname with port, and
# IP address with port. If you specify a hostname or IP
# address, then Squid binds the socket to that specific
# address. This replaces the old 'tcp_incoming_address'
# option. Most likely, you do not need to bind to a specific
# address, so you can use the port number alone.
#
# The default port number is 3128.
#
# If you are running Squid in accelerator mode, then you
# probably want to listen on port 80 also, or instead.
#
# The -a command line option will override the *first* port
# number listed here. That option will NOT override an IP
# address, however.
#
# You may specify multiple socket addresses on multiple lines.
#
#Default:
# http_port 3128
# TAG: icp_port
# The port number where Squid sends and receives ICP queries to
# and from neighbor caches. Default is 3130. To disable use
# "0". May be overridden with -u on the command line.
#
#Default:
# icp_port 3130
# TAG: htcp_port
# Note: This option is only available if Squid is rebuilt with the
# --enable-htcp option
#
# The port number where Squid sends and receives HTCP queries to
# and from neighbor caches. Default is 4827. To disable use
# "0".
#
# To enable this option, you must use --enable-htcp with the
# configure script.
#
#Default:
# htcp_port 4827
# TAG: mcast_groups
# This tag specifies a list of multicast groups which your server
# should join to receive multicasted ICP queries.
#
# NOTE! Be very careful what you put here! Be sure you
# understand the difference between an ICP _query_ and an ICP
# _reply_. This option is to be set only if you want to RECEIVE
# multicast queries. Do NOT set this option to SEND multicast
# ICP (use cache_peer for that). ICP replies are always sent via
# unicast, so this option does not affect whether or not you will
# receive replies from multicast group members.
#
# You must be very careful to NOT use a multicast address which
# is already in use by another group of caches.
#
# If you are unsure about multicast, please read the Multicast
# chapter in the Squid FAQ (http://www.squid-cache.org/FAQ/).
#
# Usage: mcast_groups 239.128.16.128 224.0.1.20
#
# By default, Squid doesn't listen on any multicast groups.
#
#Default:
# none
# TAG: tcp_outgoing_address
# TAG: udp_incoming_address
# TAG: udp_outgoing_address
# Usage: tcp_incoming_address 10.20.30.40
# udp_outgoing_address fully.qualified.domain.name
#
# tcp_outgoing_address is used for connections made to remote
# servers and other caches.
# udp_incoming_address is used for the ICP socket receiving packets
# from other caches.
# udp_outgoing_address is used for ICP packets sent out to other
# caches.
#
# The default behavior is to not bind to any specific address.
#
# A *_incoming_address value of 0.0.0.0 indicates that Squid should
# listen on all available interfaces.
#
# If udp_outgoing_address is set to 255.255.255.255 (the default)
# then it will use the same socket as udp_incoming_address. Only
# change this if you want to have ICP queries sent using another
# address than where this Squid listens for ICP queries from other
# caches.
#
# NOTE, udp_incoming_address and udp_outgoing_address can not
# have the same value since they both use port 3130.
#
# NOTE, tcp_incoming_address has been removed. You can now
# specify IP addresses on the 'http_port' line.
#
#Default:
# tcp_outgoing_address 255.255.255.255
# udp_incoming_address 0.0.0.0
# udp_outgoing_address 255.255.255.255
# OPTIONS WHICH AFFECT THE NEIGHBOR SELECTION ALGORITHM
# -----------------------------------------------------------------------------
# TAG: cache_peer
# To specify other caches in a hierarchy, use the format:
#
# cache_peer hostname type http_port icp_port
#
# For example,
#
# # proxy icp
# # hostname type port port options
# # -------------------- -------- ----- ----- -----------
# cache_peer parent.foo.net parent 3128 3130 [proxy-only]
# cache_peer sib1.foo.net sibling 3128 3130 [proxy-only]
# cache_peer sib2.foo.net sibling 3128 3130 [proxy-only]
#
# type: either 'parent', 'sibling', or 'multicast'.
#
# proxy_port: The port number where the cache listens for proxy
# requests.
#
# icp_port: Used for querying neighbor caches about
# objects. To have a non-ICP neighbor
# specify '7' for the ICP port and make sure the
# neighbor machine has the UDP echo port
# enabled in its /etc/inetd.conf file.
#
# options: proxy-only
# weight=n
# ttl=n
# no-query
# default
# round-robin
# multicast-responder
# closest-only
# no-digest
# no-netdb-exchange
# no-delay
# login=user:password
# connect-timeout=nn
# digest-url=url
# allow-miss
#
# use 'proxy-only' to specify that objects fetched
# from this cache should not be saved locally.
#
# use 'weight=n' to specify a weighted parent.
# The weight must be an integer. The default weight
# is 1, larger weights are favored more.
#
# use 'ttl=n' to specify a IP multicast TTL to use
# when sending an ICP queries to this address.
# Only useful when sending to a multicast group.
# Because we don't accept ICP replies from random
# hosts, you...
