| ifconfig -a after:

| 
| ifconfig -a before is the same except ppp0 not present.
| 
| I do not remember exact ppp options, I'll send them later.
| 
| They are something like:
| 
| nodeflate
| nobsdcomp
| noauth
| pty "pptp xx.xx.xx.xx --nolaunchpppd"
| connect sh -c 'true'
| name dilmah
| remotename PPTP
| ipparam corbina


I don't know. I have not used pptp before. It could be that pptp configures
the network interface and pppd tries to do it again.
