Tittel: Fedora Core 2: pptpd/mppe_compress fails with osize too small
Skrevet av: ATC på 27. ſeptember 2008, 18:24 pm

After installing the MPPE kernel module as per http://pptpclient.sourceforge.net/howto-fedora-core-2.phtml
certain protocols like telnet, SSH, icmp and IRC get through the VPN but protocols such as HTTP and SMB do not.

The log file /var/log/messages repeats messages like this:

"Aug  2 22:40:57 hostname kernel: mppe_compress[0]: osize too small! (have: 1400 need: 1404)"


Inspection of the VPN network device using "ifconfig" shows nothing unusual:

ppp0      Link encap:Point-to-Point Protocol  
          inet addr:10.0.10.1  P-t-P:10.0.10.100  Mask:255.255.255.255

Check the kernel version using "uname -a".
We found that the problem disappeared after upgrading to version 2.6.10-1.771_FC2
