> Is there nothing listening on *any* port 88/UDP ? or is it just on a different IP?
Nothing on port 88/UDP for any IP, if I'm understanding lsof correctly. Likewise nothing on any port 389/UDP: leo@blackbox:~$ sudo lsof | grep UDP named 1114 bind 512u IPv6 8584 0t0 UDP *:domain named 1114 bind 513u IPv4 8589 0t0 UDP localhost:domain named 1114 bind 514u IPv4 8591 0t0 UDP blackbox:domain named 1114 bind 515u IPv4 9501 0t0 UDP 192.168.122.1:domain samba 1214 root 22u IPv4 8899 0t0 UDP *:netbios-ns samba 1214 root 23u IPv4 8900 0t0 UDP *:netbios-dgm samba 1214 root 24u IPv4 8901 0t0 UDP 10.37.55.255:netbios-ns samba 1214 root 25u IPv4 8902 0t0 UDP blackbox:netbios-ns samba 1214 root 26u IPv4 8903 0t0 UDP 10.37.55.255:netbios-dgm samba 1214 root 27u IPv4 8904 0t0 UDP blackbox:netbios-dgm dnsmasq 1243 libvirt-dnsmasq 5u IPv4 8936 0t0 UDP *:bootps dnsmasq 1243 libvirt-dnsmasq 6u IPv4 8942 0t0 UDP 192.168.122.1:domain leo@blackbox:~$ This is the same as the sudo lsof | grep UDP output provided in comment #5 - except that for some reason these IP/port combinations now no longer get (specific) listeners: samba 1298 root 24u IPv4 7075 0t0 UDP 192.168.122.255:netbios-ns samba 1298 root 25u IPv4 7076 0t0 UDP 192.168.122.1:netbios-ns samba 1298 root 26u IPv4 7077 0t0 UDP 192.168.122.255:netbios-dgm samba 1298 root 27u IPv4 7078 0t0 UDP 192.168.122.1:netbios-dgm Again, this is when the machine has been started with the Ethernet cable plugged in: the lsof results when the system has been started with the cable plugged *out* are in comment #13. (Also compare the sudo lsof | grep *TCP* output after a cable-in boot (comment #5) and a cable-out boot (comment #13): there are also TCP ports without listeners in the cable-in case.) > Is there any output in the log file? Nothing is written to /var/log/samba/log.samba when kinit is run, and nothing relevant is written to /var/log/syslog either. This is true regardless of whether the machine was last started with the Ethernet cable plugged out (and thus has samba processes listening on 88/UDP) or not. There *are* system-startup-time error messages in /var/log/samba/log.samba , and they are different depending on whether the Ethernet cable was plugged in or not. I'll upload those next, along with the corresponding /var/log/syslog entries. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/976138 Title: kerberos setup fails, with broken krb5.conf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba4/+bug/976138/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
