VRRP and SIOCSIFLLADDR

2002-05-18 Thread E.B. Dreger
Greetings all, I'm currently STFWing for info on proper VRRP implementation on FreeBSD. My motivations are those mentioned by Terry in a -net thread last July... Win2000 Advanced Server clustering is rather cool. I'd like FreeBSD to similarly support multiple MAC addresses (and emulate via mul

KRB5 + hacked portmap + ypserv

2001-12-08 Thread E.B. Dreger
Greetings all, I've been looking into running KRB5 and NIS. Alas, portmapped services are somewhat firewall-unfriendly, a la FTP. True, deny-by-default "keeps the bad guys out", but I can think of instances where one might want to allow selected access from specific IP addresses... It also see

Greetings all, Sorry for the hefty cross-post... I've been digging through archives, and it seems that there was talk of this on -current late October of 2000, including speculation that this was an SMPng issue. I'm running a D-Link DFE570TX four-port dc (21143xx, where xx is TD if memory serves

outbound SOCK_STREAM - force source addr?

2001-09-08 Thread E.B. Dreger
Greetings all, Any way to force the source address for an outbound SOCK_STREAM? I know that one can do it for SOCK_DGRAM... but I've found no way to do so for, say, a TCP connection. Example: + dc0 has 192.168.0.1/24 as primary IP, 192.168.0.2/24 as alias + an outbound connection wishes to "co

TCP intercept?

2001-04-22 Thread E.B. Dreger
Greetings all, I'm no kernel hacker, and trying to think of useful little projects to change that. ;-) AFAIK, FreeBSD lacks support for TCP intercept. Is anyone already working on this? Would it be of interest to anyone? My initial thoughts are that it should be implemented in the same neighb
