>From Stephan comment 14: "Hm, of course, if one starts dhclient in debug mode (foreground) by adding a "-d", everything does work."
Yes, that does seem to work, but only for about another day, at least in my case. Thereafter, my ISP stopped returning my domain name, host name and some other stuff, and would only renew the lease for 1 hour instead of the normal 1 day. I suppose it doesn't matter because, I use supersede directives for that stuff anyhow. From my tcpdump captures, I have not been able to determine what, if anything, is different in the request, including the option parameter list request. In my opinion, this bug report should have an importance level of critical. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to isc-dhcp in Ubuntu. https://bugs.launchpad.net/bugs/1551351 Title: dhclient does not renew leases Status in bind9 package in Ubuntu: Confirmed Status in isc-dhcp package in Ubuntu: Confirmed Status in bind9 source package in Xenial: Confirmed Status in isc-dhcp source package in Xenial: Confirmed Bug description: Release: Xenial I think this only recently started after some bind9 updates triggered a rebuild. When booting dhclient gets started and acquires an IP address, but it does seem to lock up somewhere as it does not renew the lease. In my environment I set the lease time to 5 minutes, so I notice such things rather soon. I looked on the dhcp server side but saw any further dhcp messages come in from the client side.
