natd bug with pptp, hack fix, question

With natd+ipfw, I was setting up a front-end firewall for a client. The firewall has several real IP addresses (we'll call them 10.0.0.1 and 10.0.0.2) and two MS PPTP servers behind it. 10.0.0.1 10.0.0.2 World- | firewall | - PPTP-1 192.168.1.1

Changing socket buffer timeout to a u_long?

Are there compelling reasons not to change the socket buffer timeout to a u_long from a u_short? This variable stores the number of ticks before the socket operation times out. At present, the maximum SO_RCVTIMEO or SO_SNDTIMEO value one can set is SHRT_MAX / hz. With a 100Hz kernel, this comes

Re: tee option on ipfw?

The 'tee' behavior can be pretty easily emulated, however. a) use bpfilter - it automatically does a copy type thing. b) Use a little divert socket program which simply does: len = recvfrom(divert_socket, packetbuf, sizeof(packetbuf), 0, (struct sockaddr *)&from, &fromle

Er, the original TAC was a BSD utility which was rewritten by Jay Lepreau at Utah (who also happens to be my boss)... The source for it that I have sitting around (1986) doesn't actually list a copyright, but I'm fairly sure that we're in control of the copyright for that version. The authors are

Re: Netscape Bus Error

It most likely is. I've found a pretty reliable way to crash Netscape 4.6 and 4.7-freebsd (either us or export): Open two windows, and visit slashdot in both of them. Don't ask me _why_ it works, but it does. :) It causes the BSDI version to hang and chew CPU. The linux and windoze versions o
