Public SourceMage Discussion List

[Rohan Nicholls <rohan.nicholls AT answerweb.nl>]

I am sorry to do this, but seems the pptp mailing list is not very helpful
and I *REALLY* would like to be able to have sourcemage on my system as I
love it.

If anyone has any experience with pptp-linux client and getting it working
with sourcemage please let me know, as I cannot get it working and am
wondering what I was doing wrong.

The problem is obvious as I cannot cast anything without the internet
connection, which would make using sourcemage impossible.

Thanks to anyone who can help me out on this one, the explanation and all
the output I could come up with is below.

Subject: Was working in debian, but won't work in source based distro


Hi all, 

I am in deep need of help, I have tried just about everything I can think of
to no avail at the moment.

I know that debian uses an older version of pptp and, I suppose, pppd.:)

On that system, pptp ticked along happily with the adsl server, and I had an
internet connection.

Version of pppd used, mppe module taken from here and compiled into kernel
ppp-242_cvs_20021120tar.gz
Version of pptp used:
pptp-extras-120tar.gz

On this source-based distro which I like a lot this is what I did:

o unpacked ppp and pptp tarballs.
o patched the kernel sources, configured and recompiled.  Everything
went smoothly. 
**** modinfo for ppp_mppe ****
filename:
/lib/modules/2.4.19Rohan-Sept092003-with-mppe/kernel/drivers/net/ppp_mppe.o
description: <none>
author:      <none>
license:     "BSD without advertisement clause"

o compiled and installed ppp package and pppd has mppe in it:
**** output of strings pppd|grep -i 'mppe'|wc ****
     38     171    1135

o put options.adsl and options (debian default which is at the bottom
of the  file because it is soooo large.
**** options.adsl file ****
debug
idle 0
noauth
user jenandro@xs4all-basic-adsl
defaultroute
usepeerdns
nodetach
#show-password
#require-pap
refuse-chap
lcp-echo-interval 10
lcp-echo-failure 3

o ran the script below.  In my experiments since then I have commented
out the route add ... line, but the result has been the same just a
little shorter.

**** script setting up environment and calling pptp *****
#! /bin/bash


# This script configures eth0, and the router to the modem settings
# then gets eth0 up.
ifconfig eth0 down
ifconfig eth0 10.0.0.150 netmask 255.255.255.0 broadcast 10.0.0.255
ifconfig eth0 up

#displays settings for eth0
ifconfig eth0

# set the route 
#route add -net 10.0.0.0 netmask 255.255.255.0 eth0

route -n # displays the routing settings

# assuming your settings are in /etc/ppp/options.adsl
# and that pap is setup.  One thing to note that has 
# caused me no end of trouble is to escape any # chars 
# that might be in your password.:)

/usr/sbin/pptp 10.0.0.138 file /etc/ppp/options.adsl
# end of script

o When run the output is just as it had been on debian, but after the
last line there is no more activity, and I cannot connect with
anything. When run under debian, there would be lines constantly added
as, I assume, the packets went back and forth, but here no packets
travel at all.  Just below is the resolv.conf that is set by pppd, and
again it is the same as on debian.

**** resolve.conf ****
nameserver 194.109.104.104
nameserver 194.109.6.66

I have spent hours/days working on this, messing with the different
ppp settings in the options file etc.  The problem is that if I don't
have an internet connection I cannot install anything on the system,
so things are a little desperate.  I would like to stick with this
system, but if I cannot resolve this I will have to uninstall this
sytem and reinstall debian.  I have not used the php tools as I cannot
install them.:(

If anyone can help me out, or give me some ideas about how to resolve
this, I would be most grateful.  I have read all the docs on the pptp
site, the pppd man page, googled, but if there is something I am
missing please let me know.  Btw.  I am connecting through xs4all in
the Netherlands to the kpn network if that is any help.  I have read
just about everything on adsl4linux.nl, but that didn't help either.

I am happy to recompile kernels etc.:)

Thanks in advance for any help.  And if I get this working I will be
adding any docs that will help someone else out to the project.

# 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

#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>.)

# 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.

# 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.

# 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.

# 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

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(8)
# 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)
