....debian.tar.xz It would be nice if it is correctly fixed upstream. as this bug affects lot of distros. Basically the function dhcp_send() at dhcp_proto.c mistakenly define bootp.yiaddr = dev->ip_addr; when in a client originated DHCP DHCPREQUEST(RFC2131 Page 36) it should be bootp.yiaddr = INADDR_ANY; // "0" and also it forgets to define the flags bootp.flags = htons(0x800); Best, Patrick Signed-off-by: Patrick Masotta <masottaus at yahoo.com> --- diff -uprN a/klibc-2.0.4/usr/kinit/ipconfig/dhcp_proto.c b/klibc-2.0.4/usr/kinit/ipconfig/dhcp_proto.c --- a/klibc-2.0.4/usr/k...

I'm setting up a server where I plan to use Jails to improve security I also have installed and am configuring ipfilter. Here are my questions: Because I'm using Jails, I will have to have multiple ip aliases on the network interface. I will use ipfilter to specify what can go to each of the addresses. (e.g., allow only incoming to port 80 on the jail running apache). Another

...d very much *not* want to be accessible on some of its interfaces. portmap can be instructed to bind to specific addresses using the -h flag, but this seems to break ypbind. ypbind will attempt to find a server by issuing a broadcast rpc request to the local network. When portmap is not bound to INADDR_ANY, it will not reply to these requests. I'd rather not have to run ypset on clients where this condition exists with their local NIS servers, and I'd really like to not have portmap bound on certain interfaces. I could filter it of course, but I was hoping someone had another option that th...

...According to rfc 2131, page 9: "ciaddr Client IP address; only filled in if client is in BOUND, RENEW or REBINDING state and can respond to ARP requests. " Is it ideal to change "boot.ciaddr = dev-> ip_addr" to "boot.ciaddr = INADDR_ANY" in dhcp_send() function? I've used a TP-LINK TL-R402M router and it will give a DHCPNAK if ciaddr is not empty.

Cheers all, TL;DR version: I've recently found that at least on my test box the `LISTEN *` line had only set up an IPv4 `0.0.0.0` listener but not an IPv6 `::0` listener for `upsd`. In fact, at least on a "dual-stack" system, it seems impossible to bind to both - so depending on binding order I either lose IPv6 or lose IPv4 directly (but have it practically as IPv4-over-IPv6).
