# Мануал по настройке сети и VPN для kubuntu/ubuntu
После установки kubuntu устанавливаем pptp клиент (пакет, необходимый для подключения к инету через VPN):
a. открываем терминал: sudo apt-get install pptp-linux
или
b. ищем на сидюке файл pptp-linux_1.7.0-1ubuntu1_i386.deb :
/media/cdrom/pool/main/p/pptp-linux/pptp-linux_1.7.0-1ubuntu1_i386.deb
и кликаем по нему правой кнопкой мышки,
выбираем выкладку Kubuntu Package Menu->Install Package
1. От провайдера получаем следующую информацию:
1.1. YOUR_IP - твой айпишник (у меня например 10.49.15.9 )
1.2. YOUR_GATEWAY - твой шлюз ( у меня например 10.49.0.1 )
1.3. YOUR_HOST_NAME - имя твоего компа (придумай сам)
1.4. YOUR_LOGIN_NAME - имя пользователя
1.5. YOUR_PASSWORD - пароль
1.6. Метод авторизации: CHAP или PAP
1.7. Метод шифрования (mschap-v2) (если используеца шифрование)
2. Получаем от провайдера инфу и настраиваем локальную сеть:
2.1 Открываем файл /etc/network/interfaces и вставляем туда текст:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
2.2 Открываем терминал и устанавливаем сетевое имя твоего компа:
sudo /bin/hostname winged
2.3 Открываем файл /etc/resolv.conf и прописываем туда DNS:
nameserver 10.0.0.1
3. Настраиваем VPN соединение:
3.1 Открываем файл /etc/ppp/options.pptp и вставляем туда текст:
lock
noauth
nobsdcomp
nodeflate
require-mschap-v2
3.2 Оставляем файл /etc/ppp/options как есть ))

# Specify which DNS Servers the incoming Win95 or WinNT Connection should use
# Two Servers can be remotely configured
# ms-dns 192.168.1.1
# ms-dns 192.168.1.2

# ms-wins 192.168.1.51
# Run the executable or shell command specified after pppd has

asyncmap 0
# Require the peer to authenticate itself before allowing network
# packets to be sent or received.
# Please do not disable this setting. It is expected to be standard in
# future releases of pppd. Use the call option (see manpage) to disable
# authentication for specific peers.
#auth
noauth
# ... Unfortunately, fixing this properly in the peers file
# (/etc/ppp/peers/ppp0, typically) is apparently incompatible with the
# paradigm used by gnome-system-tools and system-tools-backend for
# managing the peers files. So in Ubuntu Feisty we change the default.
# Use hardware flow control (i.e. RTS/CTS) to control the flow of data
# on the serial port.
crtscts
# Use software flow control (i.e. XON/XOFF) to control the flow of data
# on the serial port.
#xonxoff
# Specifies that certain characters should be escaped on transmission
# (regardless of whether the peer requests them to be escaped with its
# async control character map). The characters to be escaped are
# specified as a list of hex numbers separated by commas. Note that
# almost any character can be specified for the escape option, unlike
# the asyncmap option which only allows control characters to be
# specified. The characters which may not be escaped are those with hex
# values 0x20 - 0x3f or 0x5e.
#escape 11,13,ff
# Don't use the modem control lines.
#local
# Specifies that pppd should use a UUCP-style lock on the serial device
# to ensure exclusive access to the device.
lock
# Don't show the passwords when logging the contents of PAP packets.
# This is the default.
hide-password
# When logging the contents of PAP packets, this option causes pppd to
# show the password string in the log message.
#show-password
# Use the modem control lines. On Ultrix, this option implies hardware
# flow control, as for the crtscts option. (This option is not fully
# implemented.)
modem
# Set the MRU [Maximum Receive Unit] value to <n> for negotiation. pppd
# will ask the peer to send packets of no more than <n> bytes. The
# minimum MRU value is 128. The default MRU value is 1500. A value of
# 296 is recommended for slow links (40 bytes for TCP/IP header + 256
# bytes of data).
#mru 542
# Set the interface netmask to <n>, a 32 bit netmask in "decimal dot"
# notation (e.g. 255.255.255.0).
#netmask 255.255.255.0
# Disables the default behaviour when no local IP address is specified,
# which is to determine (if possible) the local IP address from the
# hostname. With this option, the peer will have to supply the local IP
# address during IPCP negotiation (unless it specified explicitly on the
# command line or in an options file).
#noipdefault
# Enables the "passive" option in the LCP. With this option, pppd will
# attempt to initiate a connection; if no reply is received from the
# peer, pppd will then just wait passively for a valid LCP packet from
# the peer (instead of exiting, as it does without this option).
#passive
# With this option, pppd will not transmit LCP packets to initiate a
# connection until a valid LCP packet is received from the peer (as for
# the "passive" option with old versions of pppd).
#silent
# Don't request or allow negotiation of any options for LCP and IPCP
# (use default values).
#-all
# Disable Address/Control compression negotiation (use default, i.e.
# address/control field disabled).
#-ac
# Disable asyncmap negotiation (use the default asyncmap, i.e. escape
# all control characters).
#-am
# Don't fork to become a background process (otherwise pppd will do so
# if a serial device is specified).
#-detach
# Disable IP address negotiation (with this option, the remote IP
# address must be specified with an option on the command line or in
# an options file).
#-ip
# Disable IPCP negotiation and IP communication. This option should
# only be required if the peer is buggy and gets confused by requests
# from pppd for IPCP negotiation.
#noip
# Disable magic number negotiation. With this option, pppd cannot
# detect a looped-back line.
#-mn
# Disable MRU [Maximum Receive Unit] negotiation (use default, i.e.
# 1500).
#-mru
# Disable protocol field compression negotiation (use default, i.e.
# protocol field compression disabled).
#-pc
# Require the peer to authenticate itself using PAP.
#+pap
# Don't agree to authenticate using PAP.
#-pap
# Require the peer to authenticate itself using CHAP [Cryptographic
# Handshake Authentication Protocol] authentication.
#+chap
# Don't agree to authenticate using CHAP.
#-chap
# Disable negotiation of Van Jacobson style IP header compression (use
# default, i.e. no compression).
#-vj
# Increase debugging level (same as -d). If this option is given, pppd
# will log the contents of all control packets sent or received in a
# readable form. The packets are logged through syslog with facility
# daemon and level debug. This information can be directed to a file by
# setting up /etc/syslog.conf appropriately (see syslog.conf(5)). (If
# pppd is compiled with extra debugging enabled, it will log messages
# using facility local2 instead of daemon).
#debug
# Append the domain name <d> to the local host name for authentication
# purposes. For example, if gethostname() returns the name porsche,
# but the fully qualified domain name is porsche.Quotron.COM, you would
# use the domain option to set the domain name to Quotron.COM.
#domain <d>
# Enable debugging code in the kernel-level PPP driver. The argument n
# is a number which is the sum of the following values: 1 to enable
# general debug messages, 2 to request that the contents of received
# packets be printed, and 4 to request that the contents of transmitted
# packets be printed.
#kdebug n
# Set the MTU [Maximum Transmit Unit] value to <n>. Unless the peer
# requests a smaller value via MRU negotiation, pppd will request that
# the kernel networking code send data packets of no more than n bytes
# through the PPP network interface.
#mtu <n>
# Set the name of the local system for authentication purposes to <n>.
# This is a privileged option. With this option, pppd will use lines in the
# secrets files which have <n> as the second field when looking for a
# secret to use in authenticating the peer. In addition, unless overridden
# with the user option, <n> will be used as the name to send to the peer
# when authenticating the local system to the peer. (Note that pppd does
# not append the domain name to <n>.)
#name <n>
# Enforce the use of the hostname as the name of the local system for
# authentication purposes (overrides the name option).
#usehostname
# Set the assumed name of the remote system for authentication purposes
# to <n>.
#remotename <n>
# Add an entry to this system's ARP [Address Resolution Protocol]
# table with the IP address of the peer and the Ethernet address of this
# system.
proxyarp
# Use the system password database for authenticating the peer using
# PAP. Note: mgetty already provides this option. If this is specified
# then dialin from users using a script under Linux to fire up ppp wont work.
# login
# If this option is given, pppd will send an LCP echo-request frame to the
# peer every n seconds. Normally the peer should respond to the echo-request
# by sending an echo-reply. This option can be used with the
# lcp-echo-failure option to detect that the peer is no longer connected.
lcp-echo-interval 30
# If this option is given, pppd will presume the peer to be dead if n
# LCP echo-requests are sent without receiving a valid LCP echo-reply.
# If this happens, pppd will terminate the connection. Use of this
# option requires a non-zero value for the lcp-echo-interval parameter.
# This option can be used to enable pppd to terminate after the physical
# connection has been broken (e.g., the modem has hung up) in
# situations where no hardware modem control lines are available.
lcp-echo-failure 4
# Set the LCP restart interval (retransmission timeout) to <n> seconds
# (default 3).
#lcp-restart <n>
# Set the maximum number of LCP terminate-request transmissions to <n>
# (default 3).
#lcp-max-terminate <n>
# Set the maximum number of LCP configure-request transmissions to <n>
# (default 10).
#lcp-max-configure <n>
# Set the maximum number of LCP configure-NAKs returned before starting
# to send configure-Rejects instead to <n> (default 10).
#lcp-max-failure <n>
# Set the IPCP restart interval (retransmission timeout) to <n>
# seconds (default 3).
#ipcp-restart <n>
# Set the maximum number of IPCP terminate-request transmissions to <n>
# (default 3).
#ipcp-max-terminate <n>
# Set the maximum number of IPCP configure-request transmissions to <n>
# (default 10).
#ipcp-max-configure <n>
# Set the maximum number of IPCP configure-NAKs returned before starting

#ipcp-max-failure <n>
# Set the PAP restart interval (retransmission timeout) to <n> seconds
# (default 3).
#pap-restart <n>
# Set the maximum number of PAP authenticate-request transmissions to
# <n> (default 10).
#pap-max-authreq <n>
# Set the maximum time that pppd will wait for the peer to authenticate
# itself with PAP to <n> seconds (0 means no limit).
#pap-timeout <n>
# Set the CHAP restart interval (retransmission timeout for
# challenges) to <n> seconds (default 3).
#chap-restart <n>
# Set the maximum number of CHAP challenge transmissions to <n>
# (default 10).
#chap-max-challenge
# If this option is given, pppd will rechallenge the peer every <n>
# seconds.
#chap-interval <n>
# With this option, pppd will accept the peer's idea of our local IP
# address, even if the local IP address was specified in an option.
#ipcp-accept-local
# With this option, pppd will accept the peer's idea of its (remote) IP
# address, even if the remote IP address was specified in an option.
#ipcp-accept-remote
# Disable the IPXCP and IPX protocols.
# To let pppd pass IPX packets comment this out --- you'll probably also
# want to install ipxripd, and have the Internal IPX Network option enabled
# in your kernel. /usr/doc/HOWTO/IPX-HOWTO.gz contains more info.
noipx
# Exit once a connection has been made and terminated. This is the default,
# unless the `persist' or `demand' option has been specified.
#nopersist
# Do not exit after a connection is terminated; instead try to reopen
# the connection.
#persist
# Terminate after n consecutive failed connection attempts.
# A value of 0 means no limit. The default value is 10.
#maxfail <n>
# Initiate the link only on demand, i.e. when data traffic is present.
# With this option, the remote IP address must be specified by the user on
# the command line or in an options file. Pppd will initially configure
# the interface and enable it for IP traffic without connecting to the peer.
# When traffic is available, pppd will connect to the peer and perform
# negotiation, authentication, etc. When this is completed, pppd will
# commence passing data packets (i.e., IP packets) across the link.
#demand
# Specifies that pppd should disconnect if the link is idle for <n> seconds.
# The link is idle when no data packets (i.e. IP packets) are being sent or
# received. Note: it is not advisable to use this option with the persist
# option without the demand option. If the active-filter option is given,
# data packets which are rejected by the specified activity filter also
# count as the link being idle.
#idle <n>
# Specifies how many seconds to wait before re-initiating the link after
# it terminates. This option only has any effect if the persist or demand
# option is used. The holdoff period is not applied if the link was
# terminated because it was idle.
#holdoff <n>
# Wait for up n milliseconds after the connect script finishes for a valid
# PPP packet from the peer. At the end of this time, or when a valid PPP
# packet is received from the peer, pppd will commence negotiation by
# sending its first LCP packet. The default value is 1000 (1 second).
# This wait period only applies if the connect or pty option is used.
#connect-delay <n>
# Packet filtering: for more information, see pppd(
# Any packets matching the filter expression will be interpreted as link
# activity, and will cause a "demand" connection to be activated, and reset
# the idle connection timer. (idle option)
# The filter expression is akin to that of tcpdump(1)
#active-filter <filter-expression>

#
# /etc/ppp/pap-secrets
#
# This is a pap-secrets file to be used with the AUTO_PPP function of
# mgetty. mgetty-0.99 is preconfigured to startup pppd with the login option
# which will cause pppd to consult /etc/passwd (and /etc/shadow in turn)
# after a user has passed this file. Don't be disturbed therefore by the fact
# that this file defines logins with any password for users. /etc/passwd
# (again, /etc/shadow, too) will catch passwd mismatches.
#
# This file should block ALL users that should not be able to do AUTO_PPP.
# AUTO_PPP bypasses the usual login program so it's necessary to list all
# system userids with regular passwords here.
#
# ATTENTION: The definitions here can allow users to login without a
# password if you don't use the login option of pppd! The mgetty Debian
# package already provides this option; make sure you don't change that.
# INBOUND connections
# Every regular user can use PPP and has to use passwords from /etc/passwd
* hostname "" *
# UserIDs that cannot use PPP at all. Check your /etc/passwd and add any
# other accounts that should not be able to use pppd!
guest hostname "*" -
master hostname "*" -
root hostname "*" -

# OUTBOUND connections
# Here you should add your userid password to connect to your providers via
# PAP. The * means that the password is to be used for ANY host you connect
# to. Thus you do not have to worry about the foreign machine name. Just
# replace password with your password.
# If you have different providers with different passwords then you better
# remove the following line.
