Hi, ppp seems to be a neverending story.
I've tried to connect two BSD PC`s with modem, using ppp.
One is in my office (ppp-server). It`s connected to the internet via a switch and
a router.
I like to use my PC in the office as a gateway to the whole world for the host at
home (ppp-client).
On the client side everything seems to be ok.
I'm able to connect all the world using a ppp-server in the Universty.
Setup my own ppp-server in my office was not succesfull.
I've done the following things on the server side in my office.
-----------------------------
/etc/rc.conf:
.
.
.
.
tcp_extensions="YES"network_interfaces="fxp0 tun0 lo0
ifconfig_fxp0="inet 131.aaa.bb.222 netmask 255.255.255.0"
ifconfig_lo0="inet 127.0.0.1"
ifconfig_tun0="inet 131.aaa.bb.333 131.aaa.bb.444 netmask 255.255.255.0"
defaultrouter="131.aaa.bb.666"
static_routes="" # Set to static route list (or leave empty).
gateway_enable="YES" # Set to YES if this host will be a gateway.
router_enable="NO" # Set to YES to enable a routing daemon.
router="routed" # Name of routing daemon to use if enabled.
router_flags="-s" # Flags for roall uting daemon.
arpproxy_all="" # obsolete kernel option ARP_PROXY_ALL equiv.

/etc/ppp/options
crtscts # Hardware flow control
netmask 255.255.255.0 # netmask ( not required )
131.aaa.bb.333:131.aa.bbb.444 # ip's of local and remote hosts
# local ip must be different from one
# you assigned to the ethernet ( or other )
# interface on your machine.
# remote IP is ip address that will be
# assigned to the remote machine
domain xyz.de # your domain
passive # wait for LCP
modem # modem line
----------------------------------
/etc/ppp/ppp.linkup

131.aa.bbb.444:
# add 131.aaa.bb 0 HISADDR
#
131.aaa.bb333:
# add 131.aaa.bb.0 0 HISADDR
#
MYADDR:
# delete 0
# add 0 0 HISADDR
--------------------------------
i created a new user called ppp with this login shell
--------------------------------
#!/bin/sh -p
echo "Hello you're trying to exec ppp"
exec /usr/sbin/ppp -direct
-------------------------------
If i login as user ppp via modem from home,
i'm able to ping telnet ftp 131.aaa.bb.333 but no other host e.g.
131.aaa.bb.777
If I ping 131.aaa.bb.777
trfashow saied it answers with arp_who_has 131.aaa.bb.333
Ok this seems to be clear.
I have to use the alias option from ppp
------------------------------
#!/bin/sh -p
echo "Hello you're trying to exec ppp -alias "
exec /usr/sbin/ppp -direct -alias alias
----------------------------------
I think the label alias is not necessary and i tried it with and without
Using this i'am logged out imediatly.
If I login with out alias, open a new xterm on the the ppp-server
and use pppctl there to enable alias, this
xterm is closed automaticly (error?), the ppp connection is still up
and working. But only to 131.aaa.bb.333.
I need good ideas, what about aliasing in rc.conf with ifconfig fxp0?
