if_re NIC ping responds only after manual re-create or dhclient
I can't ping (from host or client) either of two if_re NICs I have installed on the system. I can ping to the outside from the host. I have disabled all services (HTTP, SSH, etc.) and pf for debugging. kldstat shows re/miibus, pci/re modules as loaded. Pinging just hangs with no output (192.168.1.10 is IP of one of the NICs on host): $ ping 192.168.1.10 PING 192.168.1.10 (192.168.1.10): 56 data bytes ^C --- 192.168.1.10 ping statistics --- 23 packets transmitted, 0 packets received, 100.0% packet loss If I request IP by dhclient or if I remove the assigned IP addresses and then add it back with: # ifconfig re0 192.168.1.10 delete # ifconfig re0 192.168.1.10/24 Then self-ping starts to work. Restarting the network as a service does NOT give the same result. my /etc/src.conf has: WITHOUT_INET6= yes WITHOUT_INET6_SUPPORT= yes /etc/rc.conf has: ipv6_activate_all_interfaces="NO" ip6addrctl_enable="NO" #ipv6_enable="NO" /boot/loader.conf has: ipv6_load="NO" All I can think of, is that this is either an if_re issue (highly unlikely) or an IPv6 setting conflict.

if_re NIC ping responds only after manual re-create or dhclient
I compiled a clean world and GENERIC kernel, then updated the system. I moved if_re0 to another slot on the board and installed an old if_sis in the slot previously occupied by if_re0. Just to be sure, I also installed if_fxp0 and if_rl0 cards. After re-configuring /etc/rc.conf and adding static IP's for all 5 cards (if_re1 is integrated to the mobo) I rebooted. Subsequent ping tests showed: sis0 and fxp0 can ping to itself re0, re1, rl0 cannot ping to itself. The test was repeated by changing the PCI slots where NICs were plugged-in. Unless any objections, I will file a PR on Monday. ----- FreeBSD-9.2-stable_amd64_root-on-zfs_clang-only-world -- View this message in context: http://freebsd.1045724.n5.nabble.com/if-re-NIC-ping-responds-only-after-manual-re-create-or-dhclient-tp5852849p5852917.html Sent from the freebsd-stable mailing list archive at Nabble.com.
