I've installed pppd from sarge (2.4.4), I'm using 2.6.20 with ppp_mppe loaded and followed the debian howto, checked, doubled checked and then checked the configs again.

You say you installed pptp but you are trying to use pptpconfig. passwords and stuff: /etc/ppp/chap-secrets "LOGINNAME" * "PASSWORD" * 3.call it under ubuntu pon name_it_after_your_vpn or pppd call name_it_after_your_vpn 3.1 to debug a connection pon name_it_after_your_vpn debug dump logfd 2 nodetach 4.Well I openly admit that I am too stupid to understand this, so apparently I am shut out of the priesthood.-- What he means is that the script which runs after the interface comes up is waiting for a process to finish - which seems not to happen because the process doesn't return - waiting for something? So what you could do is using the & operator in that script after you worked out which process is not returning.The instructions you have may not have been changed.As for the report that ppp0 is hanging up, this may indicate a normal problem. Read it carefully again, by going to and choosing the appropriate HOWTO from the documentation list on the left-hand side. If I type pptpconfig as non-root user, I get "command not found", not "no such command". The documentation says to run it as root, and the words "as root" link to this part of the FAQ: which also links to this part of the FAQ: which describes several ways that you could have got a message like "no such command". -- James Cameron HP Open Source, Volunteer PPTP Client Project, Release Engineer Sorry, I forgot to mention that I did read the page you sent me a link for.you can find a bit more information here regards, Konstantin 振翼 張 wrote: Hello, everyone! In my university, studen= ts in dormitory are required to access internet through VPN.But the instru= ction of how to configure the pptp client is quite old in which there is a = form for user to indicate the public network interface as eth0.PPTP uses PPP, and so with a system that has eth0 as a network interface, the first tunnel that starts will use ppp0. I don't ever seen anything logged with "GRE" in it.-- James Cameron HP Open Source, Volunteer PPTP Client Project, Release Engineer GUI for necessary configurations. tcpdump doesn't work because the ppp (ppp0) interface never gets an IP but it does get created, so something is failing pretty early in the process I guess.
