The content of /etc/resolv.conf is meant to be dynamic: VPN should be allowed to add internal servers, dialup connections have their own temporary servers that only work when the conneciton is estabilished using dialup etc... In suse, it's not possible to have static IP configuration for a device and dynamic for another device - The static configuration's DNS information gets overwritten as soon as a device with dynamic configuration (or even VPN over that static conf) is used since there's no backup location for the contents of /etc/resolv.conf. As of this issue here, I'd say it's a yast bug: NM uses DHCLIENT_MODIFY_RESOLV_CONF variable to allow/disallow updating /etc/resolv.conf and it's not possible to change the state of this variable through yast when all devices are configured to use static IP. Also, I'd say it's not possible to use one device with static and another with dynamic configuration simulatenously on suse. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

it's not possible to use one device with static and another with dynamic configuration simulatenously on suse. Maybe I don't understand but you can have eth0 static and eth1 with dhcp
IMHO this is NetworkManager bug, that user has static configuration and NM replaces his /etc/resolv.conf with empty file. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The problem is that DHCLIENT_MODIFY_RESOLV_CONF does not make sense. For the reasons, see my comment #13. It results in static IP configuration from yast does not work in NetworkManager. The workaround is to not use yast for static IP configuration, but to use NetworkManager's connection editor. I'm keeping this bug open to determine what to do post opensuse 11.0 release. There's basically two options: To make NM not read anything from yast or two make yast work with dynamic + static DNS information. As for other distros, Redhat saves the DNS list to some other file from which the tools can update resolv.conf dynamically. Debian uses resolvconf package which makes resolv.conf dynamic link pointing to the active configuration. If we don't have a solution before 11.1, NM will not read yast configuration at all. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The World does NOT run on DHCP - sorry if this is big news 2. There is no functional reason to grey out anything in Yast 3. There is no function reason why we need work arounds in any RC or Final Version Can you image how a work around created by this issue effect me with 30 + PC's I have to wait untill everyone has booted their PC and left it on - no internet access at this moment in time. Once all PC's have a OpenSuse KDE session I have to re-start the Modem and then everything works thanks to Modem smarts, however IF I need to use 1 or any more PC's - I have to start that PC with a session, ask everyone else to re-boot and then re-set the Modem. If this problem is still evident in version 11.0 - without any work around - It must be considered as a 'BLOCKER' The Yast network interface in 10.1 was so much better in layout and more useful. If it still writes the Network configuration correctly I would strongly suggest we revert back to it if we cannot get the current Interface to work. I cannot understand why a simple 'IF static IP, then auto tick 'write hosts' AND auto tick resolv.conf and then write the config statement cannot be included in Yast interface OR am I that nieve that its that simple or that easy???????? I am also alos as to why this assumed simple issue attracts #20 entries.

Fix being in 11.1 and the bug being closed as fixed in 11.0 does not seem to match. Is there any update provided for 11.0?
AFAIK there was no update needed for this issue on 11.0. It is marked FIXED (instead of WONTFIX or WORKSFORME), because we've added "fixes" - complete rewrite - to 11.1 (see comment 36) and NetworkManager does not try to follow any sysconfig settings, what caused problems in DHCLIENT_MODIFY_RESOLV_CONF=no case (comment #8). There is a pending (submitted but AFAIK not released) update for dhclient (used by NM). One of the fixes is related: it allows to override a script option defined in (old) /etc/dhclient.conf with an option provided via command line interface (NM is using own script). Workaround is to comment out the script line in /etc/dhclient.conf. Second one fixing evaluation of the sysconfig policies in the /sbin/dhclient-script [ifup corner cases with non-standard configuration]. The situation on 11.0 with ifup (NETWORKMANAGER=no) is, that yast2 writes the static nameservers directly into the /etc/resolv.conf. Yes, the "Change /etc/resolv.conf manually" is gray, but when you uncheck the "Update DNS data via DHCP" [causes DHCLIENT_MODIFY_RESOLV_CONF=no], you can define the nameservers and they are written to /etc/resolv.conf. => static DNS configuration works with ifup. When you enable "Update DNS data via DHCP" [DHCLIENT_MODIFY_RESOLV_CONF=yes], yast2 does not discard the nameservers that are already in resolv.conf. When you change an interface to use dhcp, modify_resolvconf used by dhcpcd (and pppd as well) makes a backup on connect, writes dynamic resolv.conf settings and and restores the static settings on disconnect. => dhcp DNS configuration update & restore works with ifup. When NetworkManager is enabled, it overwrites the /etc/resolv.conf (written by yast2 or not). When a connection is up and nameservers are provided by dhcp _or_ static dns server are provided, then the NetworkManager writes them into the /etc/resolv.conf. Otherwise it writes an empty resolv.conf. => static and dhcp configuration works with NM. To make the resolv.conf update work, DHCLIENT_MODIFY_RESOLV_CONF=yes needs to be set [reset to the default setting] before NM is enabled (NETWORKMANAGER=yes ; rcnetwork restart). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Ok, so what this means is that suse system configured by yast and static IP does not support:
* DHCP - I doubt your ISP allows DNS queries from a random wifi hotspot you'd like to use your laptop. * Dialup - Same reason as above. * VPN - Many corporate environments (including novell) use their own internal DNS servers that are not public and the host names won't resolve without them.
No. It is a very common mistake people make, thinking that they order of the nameservers in resolv.conf solves this problem. On linux (at least), there is _no_ way to direct local network queries to a local nameserver VPN queries to another one and ISP queries to ISP nameserver just by adding the nameservers to resolv.conf only. Also when you define 3 nameservers (vpn, local, isp) in /etc/resolv.conf, only one (first) at time is used by the resolver, except the request times out where then the resolver trys the next one. There is no "NXDOMAIN" fallback or something like this. See also "man resolv.conf": "[...] If there are multiple servers, the resolver library queries them in the order listed. [...] (The algorithm used is to try a name server, and if the query times out, try the next, until out of name servers, then repeat trying all the name servers until a maximum number of retries are made.) [...] If no nameserver entries are present, the default is to use the name server on the local machine. [...]" Solution for this, is to not to define any nameserver (or only a local one) in /etc/resolv.conf, but to install a local nameserver (bind or dnsmasq) and define forward zones there - bind example: options { forward first; # ask isp first, then try root ns include "/etc/named.d/forwarders.conf"; ### forwarders.conf content is like: # forwarders { isp.isp.isp.isp; }; }; zone "lan.example.com" in { type forward; forward only; # ask only lan ns forwarders { lan.lan.lan.lan; }; }; #zone "<lan-network>.in-addr.arpa" in { ... }; # lan reverse zone "vpn.example.com" in { type forward; forward only; # ask only vpn ns forwarders { vpn.vpn.vpn.vpn; }; }; #zone "<vpn-network>.in-addr.arpa" in { ... }; # vpn reverse On 11.0 there is the MODIFY_NAMED_CONF_DYNAMICALLY on 11.1 the NETCONFIG_DNS_FORWARDER="bind" that should help to update the ISP nameserver to configure a scenario like this. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
