More specifically, this is what I see happening: * dhclient correctly gets a DHCP lease and correctly sets the IPv4 address on the interface * if it doesn't know yet what hostname to use, netcfg prompts the user to enter one (and the DNS search domain) * right after entering those, dhclient receives SIGTERM, gives up the DHCP lease and deconfigures the interface. > Aug 11 11:12:09 netcfg[1872]: WARNING **: Started DHCP client; PID is 1919 > Aug 11 11:12:10 dhclient: DHCPDISCOVER on em0 to 255.255.255.255 port 67 interval 1 > Aug 11 11:12:10 dhclient: DHCPREQUEST on em0 to 255.255.255.255 port 67 > Aug 11 11:12:10 dhclient: DHCPOFFER from 10.0.2.2 > Aug 11 11:12:10 dhclient: DHCPACK from 10.0.2.2 > Aug 11 11:12:10 dhclient: bound to 10.0.2.15 -- renewal in 41223 seconds. > Aug 11 11:12:12 netcfg[1872]: DEBUG: Reading domain name returned via DHCP > Aug 11 11:12:12 netcfg[1872]: DEBUG: DHCP domain name is '' > Aug 11 11:12:12 netcfg[1872]: DEBUG: Reading nameservers from /etc/resolv.conf > Aug 11 11:12:12 netcfg[1872]: DEBUG: Read nameserver 10.0.2.3 > Aug 11 11:12:12 netcfg[1872]: DEBUG: State is now 1 > Aug 11 11:12:12 netcfg[1872]: DEBUG: State is now 2 > Aug 11 11:12:12 netcfg[1872]: DEBUG: State is now 5 > Aug 11 11:12:12 netcfg[1872]: DEBUG: Using DNS to try and obtain default hostname > Aug 11 11:12:12 netcfg[1872]: DEBUG: Getting default hostname from rDNS lookup of autoconfigured address fe80::5054:ff:fe12:3456 > Aug 11 11:12:12 netcfg[1872]: DEBUG: getnameinfo() returned -2 (Name or service not known) > Aug 11 11:12:12 netcfg[1872]: DEBUG: Getting default hostname from rDNS lookup of autoconfigured address 10.0.2.15 > Aug 11 11:12:12 netcfg[1872]: DEBUG: getnameinfo() returned -2 (Name or service not known) ...then hostname and domain are provided... > Aug 11 11:12:22 netcfg[1872]: DEBUG: State is now 6 > Aug 11 11:12:23 netcfg[1872]: DEBUG: Network config complete > Aug 11 11:12:23 netcfg[1872]: DEBUG: No interface given; clearing /etc/network/interfaces > Aug 11 11:12:23 netcfg[1872]: DEBUG: Writing informative header > Aug 11 11:12:23 netcfg[1872]: DEBUG: Success! > Aug 11 11:12:23 netcfg[1872]: DEBUG: Writing loopback interface > Aug 11 11:12:23 netcfg[1872]: DEBUG: Success! > Aug 11 11:12:23 netcfg[1872]: DEBUG: Writing DHCP stanza for em0 > Aug 11 11:12:23 netcfg[1872]: INFO: No hotpluggable devices are present in the system. > Aug 11 11:12:23 netcfg[1872]: DEBUG: Success! > Aug 11 11:12:23 dhclient: Received signal 15, initiating shutdown. > Aug 11 11:12:23 dhclient: DHCPRELEASE on em0 to 10.0.2.2 port 67 Incriminating code is at: http://anonscm.debian.org/cgit/d-i/netcfg.git/tree/dhcp.c#n617 Is it really intended that kill_dhcp_client will deconfigure the interface? Why was this not a problem for wheezy d-i? Is it supposed to be brought back up again in a later step? Regards, -- Steven Chamberlain steven@pyro.eu.org
