vpnd

Непрочитанное сообщение login16 » 2007-10-08 19:05:12

Привет!

Установил настроил впнд....
Но с сервера не пингуется удаленная сетка (удаленный шлюз пингуется)
И наоборот....

Я обратил внимание на сл. отрывок статьи:

Теперь вначале будет запускаться VPN а потом мой скипт, такого содержания:
/usr/local/etc/rc.d/route.sh:

Код: Выделить всё

#!/bin/sh
# на первой машине (FreeBSD6.0)
/sbin/route add 192.168.20.0/24 192.168.20.254

Код: Выделить всё

#!/bin/sh
# на второй машине (FreeBSD4.11)
/sbin/route add 192.168.10.0/24 192.168.10.254
Почему: /sbin/route add 192.168.20.0/24 192.168.20.254?
Может быть /sbin/route add 192.168.20.0/24 192.168.10.254?

Когда пингую с сервера удаленную сетку (комп в удаленной сетке), то:
ping: sendto: Invalid argument

Не могу понять...

И:
arpresolve: can't allocate llinfo for 192.168.27.1 (шлюз в офисе)
Эта ошибка выводится в логах удаленной сети :(

С этим разобрался. ЗАпустился впн- канал....

Но примерно каждый час в лог пишется ошибка:

vpnd[455]: crypto inet filed, send/receive of new key or server iv failed, will retry in 5 seconds

И впн отваливается.

Предлагаю раздраконить тот пример который прилагается к VPND.
Дабы чтобы каждый мог настроить под себя впн-канал.
Т.к. пример на англицком, давайте будем переводить и объяснять смысл каждого параметра. После чего проблем у народа с настройкой VPND не будет....

# ============================
# vpnd config file (vpnd.conf)
# ============================
#
# You will need to start a separate vpnd daemon for
# every parallel vpn connection. Each daemon will
# need it's own config file.
#
# ---------------------------------------------------
# general parameters
# ---------------------------------------------------
#
# pidfile <pathname-of-file>
#
# optional, file where pid of vpnd is stored, if not
# given no file is used, file is deleted when daemon
# terminates
#
# example: pidfile /var/run/vpnd.pid
#
# randomdev <random-number-device-file>
#
# optional, source of random data, default is /dev/random
# (/dev/srandom on OpenBSD systems and /var/run/egd-pool
# on Solaris 8 systems) which may block if insufficient
# entropy is available so you may decide to use
# /dev/urandom instead (not on Solaris 8) which should be
# safe enough but does not block,
# note that for Linux 1.x system you may have to start
# the supplied randomd daemon if you don't have a good
# random number source, in this case your random device
# is /dev/randomd
#
# example: randomdev /dev/urandom
#
# keysize <key-length-in-bytes>
#
# optional, may be used to downgrade key length, valid
# range is 0 to 72, default is 72 which is a key length
# of 72*8=576 bits, must be the same value on peer side,
# be adviced to use the longest key legally possible,
# note that keysize of 0 is unencrypted SLIP mode
#
# example: keysize 5
#
# keyttl <key-time-to-live>
#
# optional, time in minutes after which a new key has to be used,
# is ignored if mode is client as only the server generates keys,

# ignored if keysize is 0 (no key replacement)
#
# example: keyttl 30
#
# keepalive [<time-in-seconds>]
#
# optional, when given pings peer every n seconds where n is
# the optional time in seconds parameter, if parameter is not
# given default to ping every second, if keepalive is not given
# default is not to ping, ignored if keysize is 0 (no ping)
#
# example: keepalive 2
#
# noanswer <packet-amount>
#
# optional, amount of idle ping packets in serial line
# mode after which the line will be dropped if there
# is no ping reply, works only, if keepalive option
# is given, default is to drop line after 10 unanswered
# packets
#
# example: noanswer 3
#
# retry <retry-delay-time>
#
# optional, retry delay time for access and communication
# failures, default is 10 seconds
#
# example: retry 5
#
# nocompress
#
# optional, disables data compression, use only if peer

#
# example: nocompress
#
# threshold <icompression-test-threshold-size>

# transmit data to peer, default is 10 seconds

#
# linkup <process-pathname>

# is used) client port number may be given (default is any port),
# if mode is server and client ip is 0.0.0.0 no peer ip check is done,
# if client is device file device file must be located in /dev,
# if ip, server must be ip, if device, server must be device,

#
# optional, defines if HMAC should be used instead
# of a fast checksum for message authentication, 1
# for hmac-mode (only with extended key file format)
# means use HMAC if peer supports it, 2 means always
# use HMAC and fail if peer doesn't support it
# (note that the header length of any message is 4
# bytes when the checksum is used whereas  it is
# 18 or 22 bytes when HMAC is used, you will have to
# to choose between fast processing and minimal
# overhead versus additional security and message length
# as well as processing overhead, see SPEED.TXT),
# the second parameter selects the authentication
# method, if not given the default is HMAC-MD5,
# if given it is HMAC-MD5 in case of md5, HMAC-SHA1
# in case of sha1 or HMAC-RIPEMD160 in case of

#
# mtu <maximum-transfer-unit>
#
# optional, if given should be the same for server and client,

#
# optional, adds/deletes additional route when encrypted interface
# is created/dropped, during addition route1 is processed first,

#
# linktest <idle-seconds>
#
# optional, performs TCP link test if peer link was idle

# example: linktest 30
#
# oobfix
#
# optional, must be given if linktest is given for Linux kernels
# < 2.0.36 (you have to find out yourself for the 2.1.x series),

# 4 low delay type of service
# 8 priority precedence
# please keep in mind that nearly all routers do
# ignore these settings so except for very special
# environments you won't gain anything
#
# example: ipopts 10

# TCP/IP parameters (available with version 1.0.5)
# ---------------------------------------------------
#
# sendbuf <buffer-size-in-bytes>
#
# optional, sets the TCP send buffer size to the
# given buffer size in bytes, this can help if both
# interactive and bulk transfer sessions are handled
# over a slow TCP link (e.g. analogue modem), a value

# will have to find out yourself what is best for you
#
# example: sendbuf 4096
#
# connwait <connect-timeout-in-seconds>
#
# optional, used for client only, defines the maximum
# time to wait for connect to server to complete,
# if not given system imposes default time

Я так понимаю, этот параметр служит для того чтобы задать длину ключа. У меня она равна 72. Зачем его задавать? Я думаю если длина ключа изменится, то канал- не поднимется.

Уважаемый, ну и рассказал бы как с этим разобрался, уже неделю :st:

заранее благадарю
