We use a PPTP VPN to our router at the office. Is there software to do this on the N800, preferably using OS2008?

Fanoush (one of the regulars here) has some info about PPTP here:

Myself, I've beeen waiting ffoor the chaos to end, but yes go to http://maemo.lancode.de and he has the needed pptp client software. Now what I don't yet know is if the OS2008 kernel includes mppe (micrsoft point to point encription[?]) built in. If so you can config things and run, if not you'll have to wait for a 3rd party kernel.

Hi,
I have flashed fanoush's 2.2007.50-2 kernel with MPPE support an I'm currently trying to load the corresponding modules - though with limited success so far.
According to Fanoush's description the modules arc4, sha1 and ppp_mppe need to be loaded, which doesn't work due to unresolved dependencies.
http://fanoush.wz.cz/maemo/#pptp
Via dmesg output I was able to figure out, that first the crypto_algapi module has to be loaded before arc4 and sha1 can be loaded. But I still don't know, what the prerequisites for ppp_mppe are.
insmod ppp_mppe just gives a
No further hint in dmesg what exactly is missing. To bad modprobe/depmod is broken on the N800. 
Currently I have the following modules loaded
Any idea which module I have to load first before I can load ppp_mppe?
Solved
I found a working lsmode sequence:
crypto_algapi
arc4
sha1
cryptomgr
blkcipher
cbc
pcbc
ecb
ppp_mpp3

I have not tried in OS2008 yet, just enabled it in kernel. Thanks for figuring out the module list. Will add it to missing OS2008 section for others. Did you manage to connect?

Just disconnecting via poff is not working.

Ok,
I know why poff doesn't work. On line 40 of /usr/bin/poff, the word getopts is a bash not ash command. go here. and get a bash install that works around the busybox conflict and then you can change the #!/bin/sh at the start of poff and pon to #!/bin/bash.

Hi!
I think, these are not strictly necessary:

BTW, I had problems with DNS and PPTP on OS 2007 (HE) and found the solution:
/etc/ppp/ip-up.local was called with the umask set such that /tmp/resolv.conf.ppp0 was created with 0600 permissions. dnsmasq running as "nobody" couldn't read it and stopped answering DNS queries.
Solution: Insert
before the end of the first "if" block in /etc/ppp/ip-up.local
This problem is fixed in OS 2008 btw.
Maybe this is useful for some people...

What do I do if i can't even insmod crypto_algapi.ko? I'm screwed aren't I...
I'm using OS2008 2.2007.51-3 and I get the error message:
insmod: cannot insert 'crypto_algapi.ko': Unknown symbol in module (-1): No such file or directory
I'll keep messing around with it, but I'm not incredibly optimistic. Just thought this should be documented haha.

EDIT: Nevermind, I'm an idiot.
