Re: pppd and DNS [WAS:Driver for 536ep-Modem does not compile]

Dear Ludwig,Just a silly question ! Is your Linux computer a laptop or a desktop ? Wolfgang seems to run openSUSE on a laptop. My wife running Fedora 16 also owns a laptop.
For my wife's computer, I did not succeed to get rid of the NetworkManager, although she does not need it. As far as it seems, all laptops on most spread Linux distributions run the NetworkManager and it is difficult to get rid of. Linux desktops are NOT configured by default to run the NetworkManager.
And this NetworkManager interferes with most IP setting up software making things more complicated to manage.
Our ISP (SFR) provided DSL modem/router seems to suffer from one same internal IP address returning two different MAC addresses which are handled as arp entries. This fact even brings a network mess onto my Windows 7 computer. I can't cure on the Windows 7 side as I am not allowed the Administrator account. Otherwise, I would have set a static arp pointing to the relevant one of the two MAC addresses.
This is what I do on my Linux desktop computer with:ip neighbor change 192.168.1.1 lladdr 00:25:15:3d:46:30 dev eth0 nud permanent
in my /etc/rc.d/rc.local And my Linux desktop suffers from strictly no network problem.My belief is that I tried this solution for my wife's laptop computer. However, she is still or again suffering from network problems. This is why I should be glad to definitely suppress the NetworkManager from her computer.

Dear Ludwig, So with NETCONFIG_DNS_POLICY=auto this would not take into account the Network Manager and you have to fall back into the kind of solution provided to Wolfgang for wvdial/ppp. I have not studied in detail how the Network Manager does work. Perhaps Jacques may give his input or you may perhaps find some litterature on the Web describing how the Network has been designed and works. On my side, I do want to use it even for my Ethernet link (was also the case for my Wifi connection) as, as soon as I log off, the network goes down. Homing a public Web site on my personal computer, it is indeed not advised to inccur a network down. Yours truly, Philippe Le 08/03/2012 10:04, Ludwig Gebauer a écrit :Hello Philippe, sorry, nameserver 127.0.0.1 in /etc/resolv.conf doesn't work. So I edited /etc/sysconfig/network/config: NETCONFIG_DNS_POLICY="STATIC_FALLBACK dsl* ppp* NetworkManager" Works, /etc/resolv.conf gets modified automatically, according to the active interface. Some explanation can be found in the original bug report: https://bugzilla.novell.com/show_bug.cgi?id=429772 ...and here, section 126.96.36.199. ("If everything else fails, read the manual!" :-) ): http://doc.opensuse.org/documentation/html/openSUSE_114/opensuse-reference/cha.basicnet.html#sec.basicnet.yast But something remains mysterious: When "N(etwork)M(anager) and ifup are two concurrent network setup mechanizms and you have to choose one of them" - how could they work together in SuSE 10.3 ??????????? (BTW: This DNS issue is far from being the only broken feature in 11.4...).

Starting the BIND Name Server at http://doc.opensuse.org/documentation/html/openSUSE/opensuse-reference/cha.dns.html This documentation and chapter matches your openSUSE version and problem. As far as I understand it, you should set 127.0.0.1 as your nameserver in /etc/resolv.conf and keep NETCONFIG_DNS_POLICY as auto as you already have. You ought to not be able to get the correct DNS servers for your DHCP connection if you otherwise proceed with /etc/resolv.conf. Again this way to proceed is very special to openSUSE and has no correspondance on Fedora.

If you don't like these services to change # /etc/resolv.conf at all, then set this variable to "no". # If unsure, leave it at the default (which is "yes"). # MODIFY_RESOLV_CONF_DYNAMICALLY="yes" in openSUSE 11.4 (where the problems with resolv.conf arise), I findinstead the following DNS relatet options:NETCONFIG_DNS_POLICY="auto" NETCONFIG_DNS_FORWARDER="resolver" NETCONFIG_DNS_FORWARDER_FALLBACK="yes" NETCONFIG_DNS_STATIC_SEARCHLIST="" NETCONFIG_DNS_STATIC_SERVERS="" NETCONFIG_DNS_RANKING="auto" Please, give me some time to read (and hopefully, unterstand) therelated man pages. Of course I would appreciate to get some hints :-)In SuSE, the default dialer is Kinternet/Qinternet, not kppp. I have noexperience with kppp, am a bit short of time, so I ask for your understanding that I will not tune into this issue.Regard Ludwig -------- Original-Nachricht --------Datum: Fri, 02 Mar 2012 16:33:34 +0100 Von: Philippe Vouters<philippe.vouters@xxxxxxxxxxx> An: Wolfgang Junker<junker@xxxxxxxxxxxxxxxxxxx>, LudwigGebauer<ludwiggebauer@xxxxxxx>CC: Jacques Goldberg<goldberg@xxxxxxxxxxxxxxxxxxxx>,discuss@xxxxxxxxxxxxx, olivares14031@xxxxxxxxxBetreff: Re: pppd and DNS [WAS:Driver for 536ep-Modem does notcompile]Wolfgang, Ludwig, Would such information be of some help for you to configure kppp ? http://www.nairaland.com/nigeria/topic-259411.0.html Regards, Philippe Le 01/03/2012 00:02, Wolfgang Junker a écrit :Dear Philippe, I think your hint tohttps://bugzilla.novell.com/show_bug.cgi?id=465679really solves the problem: I didn't understand what they were saying but I have put NETCONFIG_DNS_POLICY="STATIC_FALLBACK ppp0 NetworkManager" into my /etc/sysconfig/network/config (or equivalently into the maskofthe editor of YAST for the Network-configuration under/etc/sysconfig).Now if I plug off the ethernet cable and do $wvdial I get a working internet connection and ppp's DNS-address is dynamically added to /etc/resolv.conf: search localdomain site nameserver 188.8.131.52 nameserver 184.108.40.206 nameserver 192.168.0.1 I still couldn't make kppp work (it says "modem doesn't answer") but I hope to resolve this issue also.

Now please can you tell us if there is or not a line usepeerdns in your file /etc/ppp/options If there is not, please add that line. Then please try to connect to your analog modem ISP with wvdial and Auto DNS = yes, do not worry for what there is or not in/etc/resolv.confbecause in this case pppd should NOT use /etc/resolv.conf,disconnectthe cable from DSL to PC to make sure that you use the analogmodem,and try to surf the Web, like Google or others. Does it work? If it works (it should), reconnect your DSL, make it work by addingtheDSL DNS in /etc/resolv.conf if necessary (see Note) and give the following commands in a separate window as superuser (the firsttakestime), while wvdial (pppd) is still running: updatedb ,then thislongcomposite command for f in `locate resolv.conf* `;do echo $f;cat $f;done so that you can see the contents of the various resolv.conf present on your computer. Note: if your DSL box is not old, and I am sure you were given abrandnew one since DSL is new in your place, configure your PC (Linux)forthe DSL connection to take DNS's from the DSL box (do not define /etc/resolv.conf and make it clear in the network s\manager definitions, no local name server, no local DNS). Your DSL boxnormallycomes configured such that the DSL box takes itself automaticallytheDNS addresses from the network. You may want,and even need, tocheckthat your DSL box is configured like that. That way you should nothearof DNS's any more once you have usepeerdns in your /etc/ppp/options . Regards Jacques n 02/29/012 02:00 PM, Ludwig Gebauer wroteresolv.conf With "Auto DNS = yes" in wvdial.conf, DNS addresses show up in the wvdial protocol, when running wvdial (ISP: www.yooline.de ),whethernetwork manager is activated or not. wi And whether network managerisactivated or not, I have to edit resolv.conf manually. Since a few weeks, DSL exists here in my village, 12 km afar from Brunswick (so much about the highly industrialisated etc. country Germany), and withmyDSL _modem_ (not a modem _router_!) I have the same effect: DNSaddressesmust be transferred manually to resolv.conf.
