Ok, so I'm completely confused. I'm trying to set up (iij)ppp from home
(running 2.0.5) to my machine at work using slirp, and I'm not having much
success. I've obviously got something configured incorrectly, but what?!
I've gone through the FAQ and everything else I could find to no avail.
If anyone could shed any light on what I'm doing wrong, I'd _really_
appreciate it.
What I want is...
Home (mini 10.0.2.15) -> ppp -> Work (mirage 158.58.29.28) -> internet
Here's what I have currently for the config files on my machine at home (the
slirp end is pretty simple with mtu, mru, baud rate and accmap - of all 'f'
just to make sure) -
(sysconfig)
hostname=mini.chicago.com
defaultdomainname=NO
network_interfaces="lo0 tun0"
ifconfig_lo0="inet localhost"
ifconfig_tun0="inet mini.chicago.com 158.58.29.28 netmask 0xfffffc00"
This is the netmask uses at work, ^^^^^^^^^^
is it what I should be using?
Also, it changes once ppp has connected - see below
route_multicast="224.0.0.0 -netmask 0xf0000000 -interface ${hostname}"
route_loopback="${hostname} localhost"
defaultrouter=NO
routedflags=-s
(hosts)
127.0.0.1 localhost loghost
10.0.2.15 mini.chicago.com mini
158.58.29.28 mirage
(resolv.conf)
nameserver 158.58.8.57
nameserver 158.58.8.17
(host.conf)
hosts
bind
After rebooting the machine, checking with 'ifconfig -a' and 'netstat -r'
shows the following:
$ ifconfig -a
lp0: flags=810<POINTOPOINT,SIMPLEX> mtu 1500
lo0: flags=8009<UP,LOOPBACK,MULTICAST> mtu 16384
inet 127.0.0.1 netmask 0xff000000
ppp0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
tun0: flags=51<UP,POINTOPOINT,RUNNING> mtu 1500
inet 10.0.2.15 --> 158.58.29.28 netmask 0xfffffc00
$ netstat -r
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif Expire
mini.chicago.com localhost UH 0 0 lo0
localhost localhost UH 0 0 lo0
My ppp.conf and ppp.linkup look like this:
default:
set device /dev/cuaa0
set speed 38400
disable lqr
deny lqr
set dial "xxxxxxxxx"
work:
set phone 15551111
set login "xxxxxxxxxx"
set ifaddr 10.0.2.15 158.58.29.28
add 0 255.255.252.0 158.58.29.28
set accmap ffffffff
After manually logging in using 'term'inal mode in ppp I run slirp on my
machine at work and then when it says 'ready' ppp takes over and starts the
connection process. Checking things at this point shows the following (the
'ifconfig -a' is wierd, what happened to my netmask?):
$ ifconfig -a
lp0: flags=810<POINTOPOINT,SIMPLEX> mtu 1500
lo0: flags=8009<UP,LOOPBACK,MULTICAST> mtu 16384
inet 127.0.0.1 netmask 0xff000000
ppp0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
tun0: flags=51<UP,POINTOPOINT,RUNNING> mtu 1500
inet 10.0.2.15 --> 158.58.29.28 netmask 0xff000000

I think that's it. As I said, any information would be appreciated.
