Package: isc-dhcp-client
Version: 4.2.4-3
Severity: normal
The dhclientconf(5) man page says:
The retry statement
retry time;
The retry statement determines the time that must pass after the client
has determined that there is no DHCP server present before it tries
again to contact a DHCP server. By default, this is five minutes.
But after my machine booted, /var/log/syslog shows concerning dhclient:
Nov 17 13:24:46 ypig dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67
interval 8
Nov 17 13:24:54 ypig dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67
interval 16
Nov 17 13:25:10 ypig dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67
interval 19
Nov 17 13:25:29 ypig dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67
interval 11
Nov 17 13:25:40 ypig dhclient: No DHCPOFFERS received.
Nov 17 13:25:40 ypig dhclient: Unable to obtain a lease on first try. Exiting.
i.e. dhclient exited instead of retrying after 5 minutes (and because
of that, I lost one hour to go to my lab to restart the network with
a "ifup eth0").
This bug is reproducible, even if I uncomment the retry line of the
/etc/dhcp/dhclient.conf file to have:
retry 60;
A working workaround is to set "timeout" to a huge value.
Either the "retry" feature or the documentation should be fixed.
