Package: network-manager Version: 1.6.2-3+deb9u2 Severity: important After booting my computer I check in /etc/resolv.conf and see only one of my search domain, namely the second one provided which is called white:
will@kodlix:~$ cat /etc/resolv.conf # Generated by NetworkManager search white nameserver 10.187.204.3 nameserver 10.187.204.1 will@kodlix:~$ But I have two domains, blue and white, and my DHCP server sends these to this computer. I have found the following command fixes it temporarily: root@kodlix:~# dhclient enp2s0 RTNETLINK answers: File exists And now resolve.conf is correct: root@kodlix:~# cat /etc/resolv.conf search blue. white. nameserver 10.187.204.3 nameserver 10.187.204.1 root@kodlix:~# If I uninstall network-manager and setup /etc/network/interface with the following contents: # WPB auto enp2s0 iface enp2s0 inet dhcp and reboot I get the correct search line, i.e. both domains appear, blue and white: will@kodlix:~$ cat /etc/resolv.conf search blue. white. nameserver 10.187.204.3 nameserver 10.187.204.1 will@kodlix:~$ I now get both domains, albeit with a . on the end, but things work now. By the way, all the other clients on my network get the correct search domains blue and white in that order, so the dhcp server config is correct. (These other clients are raspbian stretch computers and Windows 10 computers, and I checked my mobile phone DHCP values too.) Finally, I see the following in /var/log/syslog, in case that helps: Mar 7 21:49:24 kodlix NetworkManager[423]: <info> [1551995364.8466] dhcp (enp2s0): domain search 'blue.' Mar 7 21:49:24 kodlix avahi-daemon[425]: New relevant interface enp2s0.IPv4 for mDNS. Mar 7 21:49:24 kodlix NetworkManager[423]: <info> [1551995364.8466] dhcp (enp2s0): domain search 'white.' It's as if the second domain search entry simply replaces the first one. So for now I have uninstalled network-manager and just rely on /etc/network/interface which works ok as shown above. -- System Information: Debian Release: 9.8 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-8-amd64 (SMP w/4 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages network-manager depends on: ii adduser 3.115 ii dbus 1.10.26-0+deb9u1 ii init-system-helpers 1.48 ii libaudit1 1:2.6.7-2 ii libbluetooth3 5.43-2+deb9u1 ii libc6 2.24-11+deb9u4 ii libglib2.0-0 2.50.3-2 ii libgnutls30 3.5.8-5+deb9u4 ii libgudev-1.0-0 230-3 ii libjansson4 2.9-1 ii libmm-glib0 1.6.4-1 ii libndp0 1.6-1+b1 ii libnewt0.52 0.52.19-1+b1 ii libnl-3-200 3.2.27-2 ii libnm0 1.6.2-3+deb9u2 ii libpam-systemd 232-25+deb9u9 ii libpolkit-agent-1-0 0.105-18+deb9u1 ii libpolkit-gobject-1-0 0.105-18+deb9u1 ii libreadline7 7.0-3 ii libselinux1 2.6-3+b3 ii libsoup2.4-1 2.56.0-2+deb9u2 ii libsystemd0 232-25+deb9u9 ii libteamdctl0 1.26-1+b1 ii libuuid1 2.29.2-1+deb9u1 ii lsb-base 9.20161125 ii policykit-1 0.105-18+deb9u1 ii udev 232-25+deb9u9 ii wpasupplicant 2:2.4-1+deb9u2 Versions of packages network-manager recommends: ii crda 3.18-1 ii dnsmasq-base 2.76-5+deb9u2 ii iptables 1.6.0+snapshot20161117-6 ii iputils-arping 3:20161105-1 ii isc-dhcp-client 4.3.5-3+deb9u1 ii modemmanager 1.6.4-1 ii ppp 2.4.7-1+4 Versions of packages network-manager suggests: pn libteam-utils <none> -- no debconf information
