When trying to use PPTP for a vpn connection to work all seems to work well except for the following error: Mar 22 08:48:59 pc1 kernel: Not enough space to encrypt packet: 1304<1304+4! After doing some research I found an article regarding this error and there was a kernel patch. I down loaded the patch and when I tried to apply the patch I found that the patch was already applied. But yet the error still occurs. I am using SuSE 7.3 professional with the 2.4.16 kernel update applied as well as all other updates from the ftp site. I also have a laptop with 7.3 kernel 2.4.10 that gives me the same error. Is there something I am missing here? Is there something that needs to be set in the proc (echo 1 > /proc/somewhere). Thanks for your help in this matter, -- Ken Schneider Senior UNIX Administrator Network Administrator
Hi Ken I have this same configuration - I use PPTP to connect to our office lan via MS VPN. I also ran into this error, but found for my copy of the SuSE 2.4.16 kernel, the patch was not applied. I applied the patch, rebuilt the kernel and modules, and moved the new ppp module into the appropriate place. That fixed the problem for me. YMMV, of course. -ronc On Friday 22 March 2002 09:30 am, you wrote:

Hi Ron, i also installed on a SuSE 7.2 Box the 2.5.16-kernel source and apply the following patches: linux-2.4.16-openssl-0.9.6b-mppe.patch ppp-2.4.1-openssl-0.9.6-mppe-patch ppp-2.4.1-MSCHAPv2-fix.patch require-mppe.diff After compiling and installing the kernel i get the same error: GRE: read error: Protocol not available CTRL: PTY read or GRE write failed (pty,gre)=(5,6) Hmmm...this only happens if a Linuxclient try to connect. For Windowsclients the pptpd works...strange... Best regards, Kai.

We only have Linux-pptp-clients so it would be better if windows does'nt work instead of linux :) But i'm working on it ;) Is there a better alternative that can work with dynamic ip ? Times ago i use cipe (but it doen'nt support dynamic ip't at this time).

Best regards, Kai.

The PPTP client from the PPTP project on SourceForge http://sourceforge.net/projects/pptpclient/ works quite well with MS PPTP and MS VPN servers. They just did another release, although I have not had to upgrade. The PPTP client works with dynamic IP - I have mine set up that way, and sets the route tables correctly once the PPTP link is up. The only patch that I had to apply was the ppp_generic.c patch to the kernel ppp modules. I suggest that you subscribe to the PPTP mailing list and post your questions there; the developers can help you much better than I :-) -ronc
