While y'all are looking at MTU (which is an increasingly important topic as we move into a Gig+ world) I'm wondering what our support is for https://tools.ietf.org/html/rfc4821 ?? I asked this a while back and never got an answer. This method of PMTUD is really important given the massive (stupid)

System doesn't detect unplugged network cable and doesn't set interface up properly with DHCP

2012-07-12 Thread Yuri
I have the simplest possible DHCP setup: ifconfig_re0="DHCP" in /etc/rc.conf. When the system boots, it gets connected fine. Now, I disconnect my laptop and connect it to another network. When cable is disconnected, IP address of this interface stays the same, old one is not removed. When I p

Thats pretty standard for BSD and most Unixes. DHCP hands out leases for a specified period of time, so unless there is a reason to reset it, it wont. Windows does that, but it is designed more as a client / user facing OS whereas BSD is designed to run in the background silently serving you cont

Maybe another option to dhclient to have it poll the interface every 2-3 seconds to see if it has lost a link and if so, set the lease timer to be expired, and wait for it to come back and once it does, it will acquire a new address. ___ freebsd-net@freeb

Hi, I have an HP ProLiant DL360p Gen8 server in my possession for testing, and it appears the Broadcom NetXtreme BCM5719 doesn't yet have support. I noticed someone asking about server support on freebsd-questions last month, but it didn't garner much attention. Played around with 8.3-RELEASE, 8-
