PPTP requires modifications to each container to actually support it, the devices need to be made for you and many kernel modules need to be loaded on the node.
There isn't any public automation to allow this, and we ended up simply writing our own code to handle this when we started.

hi francisco,
thanks for reply
what i am curious is that even the container enabled tun/tap, the pptp to android was still a panic, able to connect but fail to load pages from internet.
so do you mean it's related to the OS template and it's tailor made for pptp usage, am i getting your meaning right( sorry my english was bad)
If it's not letting you browse through the VPN, it's quite possible that your forwarding isn't set. Check in /etc/sysctl.conf , and make sure
net.ipv4.ip_forward=1
is uncommented. Afterwards, runsysctl -p
or restart the VPS for it to take effect.thanks aldryic.
i did edit sysctl.conf and running 'sysctl -p'
it work very well on iphone but not the android phone.
that's why i am curious if it's related OS template.
Hrm, now that's odd. I wonder if it is Droid-related... I just tested pptp on debian with my own 'Droid (on the HTC HD2), and also could not establish a connection. Check your
tail /var/logs/syslog
, see if you get something like this:I probably won't have time to really look into it this weekend, but perhaps sometime early next week I can dive in and see what I can figure out.
that's the point.
I can connect to and surf net from buyvm built pptp.
but i can't do it from other openvz provider.
that's what i want to know how to do it.
besides,
i firstly think of mtu problem.
so i just use iptables and the pptpd configuration files to set mtu.
but still failed.~
I'm not sure if this specifically applies to this problem, but run a search on google for pptp and android and a lot of people are have/had issues with it.
So your BuyVM works for your Droid, then? Or did I misread that?
(I'm testing on my own BuyVM, though hadn't tried connecting with anything other than my droid yet)
i am using S2.
wonder if it's S2 issues.
would it be the kernel makes pptpd effective to android phones?
PPTPD is PPTPD, what I can recommend is make sure you're using poptop
Francisco
@.. i am a bit dizzy now.
so wat i am using is pptpd, am i right?
i use "aptitude install pptpd" command.
This is getting confusing...
Conclusion: If pptpd works in BuyVM, good for you.
Most providers doesn't have these modules enabled, thats why doesn't work.
thanks,
another providers says they enabled ppp modules as buyvm did.
while using other providers, i could connect to poptop(pptpd), but fail to surf net, even forward gre and 1723 as well as NAT.
while buyvm can.
what my confusion is that.
i want to know if it's the kernel make the android-to-poptop(pptpd) works.
if the answer was really about the kernel.
i could stop finding out the causes
p.s.: i knew there are many documents showing android phone have some issues on poptop(pptpd).
Many say, very few do There's a lot of modules to load as well as other things. Simply loading the kernel modules doesn't suddenly make it work.

And your iptables -L results are?
Chain PREROUTING (policy ACCEPT)
target prot opt source destination
Chain POSTROUTING (policy ACCEPT)
target prot opt source destination
SNAT all -- anywhere anywhere to:209.141.60.198
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT gre -- anywhere anywhere
ACCEPT tcp -- anywhere anywhere tcp spt:1723
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
ACCEPT gre -- anywhere anywhere
ACCEPT tcp -- anywhere anywhere tcp dpt:1723
wait, did you made your mppe module so Android phones can connect? you must share the code!
i didn't. i've googled but can't find any patch for android phones connect to mppe without issues.
If you want to use PPTPD just stick with Buyvm or look for some XEN or KVM competitors
I also had lot of troubles with openvz providers, claiming they can activate PPTPD
Got some names? I'm always curious about who's actually delivering on promises.
It isn't all that hard to activate PPTPD on OpenVZ. Some providers are just lazy I guess. Meh.

When I asked them in a support ticket, if it is possible they said no problem. When I ordered and asked for pptpd they said that they are not supporting it at the moment. I think they are operating now under a new name, aren't they?
I also remember virpus failing delivering pptpd for me back in early 2010.
This is what I remember, but I know there was a lot more providers, who failed on this.
hey... i am curious too.
even i was using xen..
pptpd was failed to use for android...
That's why I made L2TP for Androids, and PPTP for others
Just gave this a whirl on 2x OpenVZ and 1x XEN 1x KVM.
PPTPD with mppe encryption result:
Connect but cannot browse.
tcpdump -i ppp0 was showing traffic bouncing in and out, but the samsung andriod phones were a no go(time outs)
However, on Xen and KVM - IPSec/Pre-Shared work fine here.(Using first result from market for 'pptp' as the client app.)
I'm on Virpus cheapest plan and PPTP is working fine with MPP Encryption enabled, my host node doesn't have MPPC module installed, though. So no compression.
I do have working iptables NAT configs and GRE rules, so yes traffic forwarding works.
Working flawlessly when tested on my router and Windows client.
I haven't tried it with Android, yet. (I'm gonna ask my friends for letting me to use his phone like soonish)
So far it doesn't currently work on my so-yesterday S60v3 phone (using SymVPN).
I'll get back to you when when I got the result.
I have a s60v5 and I am unable to use SymVPN, some numeric error code and fail u_u You can use it somewhere?
Yep, the test VPN account provided in telexy website is working fine
try this:
-host: connect.swissvpn.net
-username & pass: swissvpntest
Obviously, you can only browse around www.swissvpn.net
Worth to be noted, the pirated version of SymVPN is known to be non-working, you'd better use their trial for proper test.
I tried the trial!
(And also that version... :P )
Same results u_u
Maybe a firmware issue
