Hi, Friends. I am writing a driver to filter all IP Packets under SCO OpenServer 5.05 now. I have successfully inserted my driver, which is implemented as a stream module, between IP driver and common DLPI module by modifying /etc/strcf.d/10tcp. But I don't know how to insert my stream module between IP driver and PPP driver (or IPF module). How can I fulfill this? BTW, I wonder why thre is no open sourced IPFilter porting under SCO OpenServer. I don't think it is difficult to port it to OpenServer since intercepting all IP Packets for NIC is very easy. Another question, why IPFilter for Solaris didn't implemented as a DLPI aware stream module and we use autopush mechanism to insert it between IP driver and underlying NIC driver (I don't know whether there is a common DLPI module under Solaris).
Thanks in advance.
