You need to use /usr/sbin/daemon or /usr/ports/sysutils/detach if your FreeBSD doesn't have deamon.

Aliasing lo0
I needed to put an alias on lo0 for 127.0.0.2 and I made the mistake of assuming this would work like any other interface but that isn't the case. ifconfig inet lo0 127.0.0.2 netmask 255.255.255.255 alias results in an ip that I can ping but when I startup dnscache and ask it to listen on that ip it won't respond to queries. ( Yes queries from the same host ) If I switch the netmask to 255.0.0.0 ( which goes completely against the man page for ifconfig ) and everything works great. Also /etc/defaults/rc.conf shows... #ifconfig_lo0_alias0="inet 127.0.0.254 netmask 0x" # Sample alias entry. If I follow that sample ( note the netmask ) things won't work right. Am I missing something or is lo0 treated differently for some reason? FreeBSD 4.5 To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message

I checked and the code in question has the same problem as the PR code, sin_len is not being reset to the proper value before each call to accept(). I will put this change in and sometime tommorow ( once the box gets some traffic ) I will know if this has fixed it. I'm betting it will. Thank you!

accept() doesn't pass back sockaddr
I am using on a web filter ( dansguardian.org ) and am having problems on FreeBSD (4.5-STABLE). The filter runs fine for about 20 minutes or so then can't seem to come up with the right ip addresses for any client machines. After much reading of man pages, Stevens, and some banging of my head against the desk I decided that maybe it wasn't me :) I found a PR that I think seems to relate (misc/34307) but this still confuses me. I would think that if the situation this PR describes were to be the case all sorts of things wouldn't be working right. I don't have a hope of fixing the PR, I can't even seem to find the source for accept(). Does anybody know of a better work around than closing the socket ( and loosing any backlog ) and re-opening it?. Thanks in advance.
