[CentOS] samba3x PDC and Win XP
I am at my wits end on this one. Ever since I upgraded to samba3x (present version 3.5.10-0.110.el5_8) in preparation for adding a Win 7 client, my WinXP client can no longer find their roaming profiles nor can they assign their home shares to a drive at login. Logins and authentication work just fine and I can see the home and profile shares from the Win XP client after login. My smb.conf file contains (here are some essential snippets): # the login script name depends on the machine name ; logon script = %m.bat # the login script name depends on the unix user used ; logon script = %u.bat logon script = logon.bat # disables profiles support by specifing an empty path ; logon path = logon path = \\%L\profile\%u\%m logon home = \\%L\%u logon drive = H: [homes] path = /mnt/home/%u comment = Home Directories browseable = no writable = yes valid users = %S guest ok = no inherit permissions = yes [profile] path = /mnt/home/profile browseable = no writeable = yes default case = lower preserve case = no short preserve case = no case sensitive = no hide files = /desktop.ini/ntuser.ini/NTUSER.*/ write list = @smbusers @smbadmins create mask = 0600 directory mask = 0700 csc policy = disable profile acls = yes I enabled debuging and from what I can tell the %u variable is not getting properly evaluated. For example for the homes share: [2012/08/01 00:28:19.471215, 3] smbd/password.c:282(register_existing_vuid) register_existing_vuid: User name: snichols Real name: [2012/08/01 00:28:19.471240, 3] smbd/password.c:292(register_existing_vuid) register_existing_vuid: UNIX uid 501 is UNIX user snichols, and will be vuid 102 [2012/08/01 00:28:19.472336, 3] smbd/password.c:223(register_homes_share) Adding homes service for user 'snichols' using home directory: '/mnt/home/snichols' [2012/08/01 00:28:19.472475, 3] param/loadparm.c:6287(lp_add_home) adding home's share [snichols] for user 'snichols' at '/mnt/home/%u' Or for the profile service: 2012/08/01 00:28:19.488457, 1] smbd/service.c:1070(make_connection_snum) sasha (192.168.1.13) connect to service profile initially as user snichols (uid=501, gid=501) (pid 25876 2012/08/01 00:28:19.489251, 3] smbd/trans2.c:5100(call_trans2qfilepathinfo) call_trans2qfilepathinfo: TRANSACT2_QPATHINFO: level = 1004 [2012/08/01 00:28:19.489364, 3] smbd/filename.c:945(get_real_filename_full_scan) scan dir didn't open dir [%u] [2012/08/01 00:28:19.489399, 3] smbd/vfs.c:881(check_reduced_name) check_reduced_name [%u/sasha] [/mnt/home/profile] [2012/08/01 00:28:19.489437, 3] smbd/vfs.c:962(check_reduced_name) check_reduced_name: couldn't get realpath for %u/sasha [2012/08/01 00:28:19.489463, 3] smbd/filename.c:1184(filename_convert) filename_convert: check_name failed for name %u/sasha with NT_STATUS_ACCESS_DENIED [2012/08/01 00:28:19.489495, 3] smbd/error.c:80(error_packet_set) error packet at smbd/trans2.c(5129) cmd=50 (SMBtrans2) NT_STATUS_ACCESS_DENIED The samba/linux user that successfully logged in is snichols.

[CentOS] SELinux : please explain ...
Hello,
This is somehow off-topic, since the problem appears on a modified
CentOS-6.2 (turned into a xen-4.1 host) : I get SELinux errors, and
I'm not able to understand them.
>From audit2why :
type=AVC msg=audit(1343724164.898:298772): avc: denied { mac_admin } for
pid=12399 comm="restore" capability=33
scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
tclass=capability2
... and from audit2allow :
#= unconfined_t ==
allow unconfined_t self:capability2 mac_admin;
I don't know what triggers these records in /var/log/audit (everything
seems to work). Running retorecon -rv / doesn't produce any error.
Can someone tell me what is the mac_admin functionnality, and if it
is safe to allow it ? If I understand correctly what I have found by
googling around, it is not advised.
Thanks,

The path in the error message was different but no cigar. I am positive that the syntax specified above is correct for the /etc/samba/smb.conf file as it is documented this way all over the web.

[CentOS] centos 4.9 + ip6tables
Hi I have an old server running centos 4.9 and recently I added ipv6 connectivity to it, however I wanted to use iptables to restrict access like im doing over ipv4. I tried using yum to install ip6tables but that's not available on the repo. I'm trying to figure out what my options are, how do you guys recommend I go about installing ip6tables. I guess I could upgrade the server from 4.9 to 5.x but I heard this could cause issues with things already installed and I have never done an upgrade like this. This is a server running chroot bind compiled manually. My other option is to use an ACL on the router the server connects to but I really wanted to get ip6tables on there.

mac_admin means some where you have a command that is trying to set a file
context to something your current policy loaded into the kernel does not
understand.
Something like
touch /tmp/foobar
chcon -t unknownlabel /tmp/foobar
Would cause this AVC.

Otherwise, I would have to maintain a list of UUIDs to add every time and to keep trying every time the script is run which doesn't sound very efficient to me. Thus it seems to me like there should be a better way to do this especially since the mechanism already appears to exist. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Configure LAGG Interface?
Greetings- I'd like to configure multiple copper NICs on a server running CentOS 6.2 in a LAGG configuration for better throughput to the core switch. After quite a bit of searching, I'm not seeing anything of the sort. Is LAGG specific to the BSD world and the HP switches I'm running? Or, does it go by a different name? Bonding perhaps? If so, is bonding compatible with LAGG? --Tim ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Thank you so much for this bit of information. I have spent 3 days on this issue and now realize I was searching the web with the wrong question. As soon as I asked for the difference between %U and %u everything becomes clear. Apparently the use of %u as I have been using it for the last 5 years was deprecated and apparently with samba3x stops working altogether. The documentation is not very clear about the difference between %u and %U. The best I could find is that %u evaluates to the Linux username and that %U evaluates to (in my case) the Win XP client username. These do not necessarily have to be the same. Therefore I always used the %u version believing I was trusting the Linux. Besides out of the box the smb.conf uses %u as I did. Live and learn I suppose. I haven't fixed my configuration yet but from what I just learned today this solution is what I was searching for the last three days. Again thank you very much for the information. -- Paul (ga...@nurdog.com) ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] CentOS 6.3 on ASUS G73S does not work external video
Hi List, just wondering which driver I need to be looking at / for that deals with the laptop's external video connector. Background - went to deliver a presentation last week and found that there was no way to get any video output to the external D-15 connector (hooked up to a video projector). 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 key did toggle the laptop screen off and on and varied the resolution of the laptop display but never any output on the external connector. I booted the laptop with the display not connected and then tried connecting it - no joy. Then rebooted with it connected and tried power on and off two times but never any signal on the external connector simply booting into w7 and it immediately worked Any ideas of what magic foo I need to get this working would be appreciated.
