Учет трафика по всем портам ipcad + LightSquid
или "Преобразование IP адресов в доменные имена в отчетах LightSquid"
По настройке связки squid+lightsquid+ipcad написана достаточно статей. Есть неприятный нюанс при просмотре статистики.
ipcad собирает статистику по IP адресам, а Squid по доменным именам.
В итоге в отчетах LightSquid мы видим:
Дабы ipcad считал все порты, надо описать их в конфиге /usr/local/etc/ipcad.conf
Я описал все открытые порты так:
aggregate 3128 into 0;
aggregate 80-81 into 0;
aggregate 20-21 into 21;
aggregate 22-23 into 22;
aggregate 25 into 25;
aggregate 26-109 into 26;
aggregate 110 into 110;
aggregate 111-142 into 111;
aggregate 143 into 143;
aggregate 144-442 into 144;
aggregate 443 into 443;
aggregate 444-992 into 444;
aggregate 993 into 993;
aggregate 994 into 994;
aggregate 995 into 995;
aggregate 996-65535 into 65535; |

##################
# GLOBAL OPTIONS #
##################
#
# Enable or disable capturing UDP and TCP port numbers, IP protocol and
# ICMP types for RSH output.
#
# capture-ports {enable|disable} ;
#
# Enabling this will BREAK Cisco RSH output format compatibility,
# increase memory requirements and may slow down traffic processing.
# This option takes effect IMMEDIATELY, that is, it can be specified
# multiple times, even between interfaces configuration.
# This option has NO effect on NetFlow operation (NetFlow always captures
# port information).
#
capture-ports enable;
#
# Buffers to be used for transferring the data from the kernel,
# if applicable (BPF, ULOG).
# Using larger buffers may increase the performance but will
# affect responsiveness.
#
# buffers = <number>[{k|m}] ;
#
# Reasonable defaults are used if this parameter is not set.
#
## buffers = 64k;
#####################
# INTERFACE OPTIONS #
#####################
#
# interface <iface> [ promisc ] [ input-only ]
# [ netflow-disable ] [ filter "<pcap_filter>" ] ;
# OR
# interface ulog group <group> [, group <group> ...]
# [ netflow-disabled ];
# OR
# interface ipq [ netflow-disabled ]; # man libipq(3)
# OR
# interface {divert|tee} port <divert-port> # man divert(4)
# [ input-only ] [ netflow-disabled ];
# OR
# interface file <tcpdump-output.pcap> [ netflow-disabled ];
#
# Options meaning:
#
# promisc:
# Put interface into promiscuous mode.
# This enables listening for the packets which are not destined for
# this host and thus ipcad will count and display all the traffic within
# the local network. Note that the interface might be in promiscuous mode
# for some other reason.
#
# input-only:
# Use kernel feature of counting only incoming packets.
#
# netflow-sampled: (DO NOT ENABLE THIS OPTION, unless you have to!)
# If the NetFlow export mechanism is used, this option instructs
# the interface to supply only one out of N packets to the NetFlow
# accounting code, thus lowering the CPU requirements. The value of N
# is configured explicitly in a NetFlow configuration section.
# NOTE: This option is NOT used to enable NetFlow on the interface,
# it just modifies the NetFlow behavior on this interface.
# DO NOT ENABLE THIS OPTION, UNLESS YOU HAVE TO!
#
# netflow-disable:
# By default, all interfaces are included into NetFlow accounting.
# This option is used to disable NetFlow on a particular interface.
#
# filter:
# Install a custom filter on packets instead of basic
# IP protocol filter. Requires libpcap (even if BPF is being used).
# May be employed to eliminate CPU overhead on passing unnecessary
# data between the kernel and user space (by installing the filter
# directly into the kernel).
#
# NOTES:
# * "input-only" directive must be supported by kernel.
# Probably, you were noticed about it during the compilation process
# if it was not supported.
# FreeBSD 3.x and elder kernels do not support this feature.
# * ULOG packet source (interface ulog) is supported under
# Linux >= 2.4.18-pre8.
# You should configure iptables to dump the packet stream
# into the appropriate group, i.e.:
# iptables -A OUTPUT -j ULOG --ulog-nlgroup <group>
# Given ULOG groups will be OR'ed together.
# * A wildcard (*) may be specified as part of an interface name.

# DO NOT ENABLE THIS UNLESS YOU KNOW WHAT ARE YOU DOING.

# Enable RSH Server:

#################
# OTHER OPTIONS #
#################
