I've also seen DSL networks like this where those extra IPs are bridged not routed. in these cases, you use the same gateway as the 'main' IP, but usually the main IP has a /24 or whatever mask that encompasses ALL the IPs. regardless, the OP should contact the ISP and find out what the mask and gateway are for the extra IPs. -- john r pierceN 37, W 122 santa cruz ca mid-left coast ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

It's very possible the OP _does_ have 8 IPs to play with but, because it's not a subnet, he may need to configure them individually.

Yes I have added those register entries and was able to join the Win 7 box to the domain just fine. I was also able to create a domain user account. I can logon with that domain user account just fine. The domain user home directory gets connected properly to drive H: and I can see the \\server\profile\user share just fine. The only thing that is not occurring is that the profile created on the Win 7 box is a local profile and not a roaming one with the caveat that if the a local Win 7 profile is not found it takes the one found on the \\server\profile\user share as a default. It is like the Win 7 box is setup to use local profiles only even if the profile is a roaming one. There are register entries you can set to make this happen but they are not present in my registry from what I can see. -- Paul ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Well last night I implemented this change and indeed this fixed the Win XP problem. The domain users on the client Win XP box can indeed find their roaming profiles and properly sync them at logon/logoff time. However when I went to add a domain user to the first Win 7 Professional box added to the domain, that user only gets a local profile (i.e. a C:\Users\username instead of C:\Users\username.domainame) despite the fact the domain user has a roaming profile. I am sure this is a Win 7 client setup issue. The best I have been able to do is copy a local profile from the Win 7 box for the domain user back to the Samba PDC. I then delete the domain user's local profile and could get the Win 7 client to read the profile from the Samba PDC on the domain user's next logon. Basically I can get the Win 7 client to create a new local profile from the profile found on the Samba PDC but on logoff the Win 7 client will not sync that profile with the Samba PDC and on subsequent logons only uses the local stored profile on the Win 7 box. It is like the Win 7 client policy is to use local profiles only and it uses the Samba PDC profile only as a default if the local profile doesn't exist. There is no subsequent profile synchronization at logon/logoff after the Win 7 local profile gets created. Any suggestions to registry/policy settings to get roaming profiles to act as roaming profiles on a Win 7 Professional SP 1 box? I thought I ask here first as I am already on this list. Admittedly this might better belong on a Samba forum but I am guessing somebody out there has already run into this issue.

Note that kernel-debug contains a debug version of the normal kernel NOT debuginfo for the normal kernel. debuginfo for the normal kernel is named kernel-debuginfo (and kernel- debuginfo-common) and is only available on vault/debuginfo (and some select mirrors like mirror.nsc.liu.se/centos-debuginfo). ...there is even debuginfo for the -debug kernel and this is (not surprisingly) named kernel-debug-debuginfo[-common..]. /Peter signature.asc Description: This is a digitally signed message part. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Eventually I re-booted to windoze 7 and all worked just fine - major embarrassment after telling everyone how great Linux was. The laptop has a nvidia GTX 460M card and I use the el-repo kmod-nvidia-295.59-1.el6.elrepo.x86_64 and nvidia-x11-drv-295.59-1.el6.elrepo.x86_64 I do have compiz-0.8.2-24.el6.x86_64 and compiz-gnome-0.8.2-24.el6.x86_64 running but as these should not be dealing directly with the hardware am not thinking they should matter. Not sure where to start trouble shooting - I tried lots of different screen resolutions via the System> Preferences> Display but no joy getting any signal out to the external connector. This laptop does have an hdmi socket but I was not using that, I thought the good old fashioned D-15 video plug should "just work" (tm). The function keydid toggle the laptop screen off and on and varied the resolution of the laptop display but never any output on the external connector. those laptop graphics chips treat the VGA connector like a 2nd monitor, I have no idea how you configure linux for multimonitor, but I know its not nearly as easy as MS Windows where it just works. Indeed that connector is treated as an "all the time on" 2nd monitor If it is an nvidia card, you can use use the NVIDIA X Server Settings link in "Menu => System => Administration" (if you install the drivers from elrepo, which I recommend) If it is another card that uses system drivers, you can use the "Menu => System => Display" I just create 2 xorg.conf files and copy the one I need into place when I hook up to my docking station on my Dell M4500. Okay - I think I understand and the idea of two xorg.conf files seems like a great idea. Will give this a try as soon as I locate another external video monitor with a VGA connector.
