Stefan, I think the answer is yes. Just a few minutes before my lease was going to expire, I did: "sudo dhclient enp4s0" However, I didn't notice any change in the leases file, so I expected internet it to stop working after the expire time, but it didn't stop working. So I looked at my tcpdump captures and realized that the lease was granted, it just didn't update the leases file.
I never killed anything first, and dhclient is still running... Oh, crap, I see I now have a bunch of dhclients running. doug@DOUG-64:~$ ps aux | grep dhcl root 1049 0.0 0.0 181364 2808 ?

Ss 08:36 0:00 dhclient enp4s0 I was just trying to avoid having a gap in internet access. I don't really want to do the ifdown && ifup method if I can avoid it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1551351 Title: dhclient does not renew leases To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/1551351/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
