HOW TO TEST SLIRP
-----------------
root@local:~# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth1
root@local:~# pppd nodefaultroute noauth nobsdcomp nodetach debug :10.1.2.1 pty "ssh -t user@remote.machine.org slirp ppp"
(if ssh asks you for a password, type it, or better, set up ssh so it allows
you connecting without password, see ssh-keygen and authorized_keys in ssh
manpages)
(you can omit later "nodetach debug" when it works so it leaves you free
the terminal)
the output should be some like this:
using channel 42
Using interface ppp0
Connect: ppp0 <--> /dev/pts/4

You can just press ^C in the terminal pppd is running (when using nodetach)
or else run "poff" or "killall pppd"
