[pkg-dhcp-devel] Bug#761850: /sbin/dhclient: dhclient exits with status code -1 when attempting to obtain a new lease

[Wouter Van Hemel]

Package: isc-dhcp-client
Version: 4.3.1-1
Severity: important
File: /sbin/dhclient

dhclient exists with status code -1 when trying to obtain a new lease. When the lease expires about 2 hours later, I have no network connectivity anymore until I restart networking and network-manager.

Sep 16 11:57:05 kkv54 dhclient: DHCPREQUEST on eth0 to 128.214.205.131 port 67
Sep 16 11:57:05 kkv54 NetworkManager[694]: <info> (eth0): DHCPv4 client pid 1107 exited with status -1
Sep 16 11:57:05 kkv54 NetworkManager[694]: <warn> DHCP client died abnormally
Sep 16 12:41:06 kkv54 systemd-udevd[5060]: Network interface NamePolicy= disabled on kernel commandline, ignoring.
Sep 16 13:18:48 kkv54 systemd-udevd[5060]: Network interface NamePolicy= disabled on kernel commandline, ignoring.
Sep 16 13:21:36 kkv54 systemd-udevd[5060]: Network interface NamePolicy= disabled on kernel commandline, ignoring.
Sep 16 14:09:03 kkv54 NetworkManager[694]: <info> caught signal 15, shutting down normally.
Sep 16 14:09:03 kkv54 NetworkManager[694]: <info> exiting (success)

I checked the code of dhclient.c but I don't see any "-1" exit codes at first sight. I have (Debian-provided) samba and ntp scripts in the enter/exit hooks. I'm not sure what would make dhclient exit, and I can't find any relevant logs beyond what I provided above.


Thanks for any insight,
