minimal X applications needed to export to remote server?
by Joseph Spenner 16 Aug '13

16 Aug '13

I'm running a piece of network backup software called 'bacula', on a minimal CentOS 6.4 install. I got everything working pretty well, but there's one piece giving me some problem-- a component which gives status info via a GUI. In the past, on previous installations, I could ssh to the bacula server with the -X option, and run the application (called 'bat'), and it would display back. I'd have to make sure the sshd_config permits Xforwarding, but that was all. On my new CentOS 6.4 minimal, I always get: bat: cannot connect to X server I tried the usual tricks of exporting the display to my system where I want to see the GUI, which shouldn't be necessary anyway due to the 'ssh -X', but I thought I'd give it a shot. Still no go. I figured something was missing, since it is a minimal install, with no X. So I installed 'xlogo', thinking maybe all the X stuff needed to display that would be installed. By installing xlogo, I got a bunch of X stuff, including: xorg-x11-apps-7.6-6.el6.x86_64 I also have: libXau-1.0.6-4.el6.x86_64 libX11-1.5.0-4.el6.x86_64 libXrender-0.9.7-2.el6.x86_64 libXcursor-1.1.13-2.el6.x86_64 libXft-2.3.1-2.el6.x86_64 libXxf86vm-1.1.2-2.el6.x86_64 libXi-1.6.1-3.el6.x86_64 libXmu-1.1.1-2.el6.x86_64 libXaw-1.0.11-2.el6.x86_64 libX11-common-1.5.0-4.el6.noarch libXext-1.3.1-2.el6.x86_64 libXfixes-5.0-3.el6.x86_64 libXdamage-1.1.3-4.el6.x86_64 libXrandr-1.4.0-1.el6.x86_64 libXinerama-1.1.2-2.el6.x86_64 libXv-1.0.7-2.el6.x86_64 libXt-1.1.3-1.el6.x86_64 libXpm-3.5.10-2.el6.x86_64 But I still get the error. Anyone know which package/rpm/lib I am missing? Thanks!

RocketRAID cards (actually, solved)
by m.roth＠5-cent.us 16 Aug '13

16 Aug '13

If anyone's got old RocketRAID cards, I just had to deal with one. They are years behind in updating their drivers - googling, I find the last time some were supported was CentOS 5.2. At any rate, I have just managed to build 1.8 of rr232x successfully, and am building filesystems on the drive as I type. I d/l the compressed tarballs from HighPoint's site. The changes to make it compile were: 1. /* if (bdev && blkdev_get(bdev, FMODE_READ, 0 __BDEV_RAW)==0) { # Above for < 2.6.28 */ if (bdev && blkdev_get(bdev, FMODE_READ)==0) { Note that the last two parms from the original call were removed. 2. /* blkdev_put(bdev __BDEV_RAW); (or, in another case, just BDEV_RAW) # above < 2.6.28 */ blkdev_put(bdev, FMODE_READ); 3. In osm_linux.h, their definition redefines what the Linux header files say. I made the following change. Note that I wanted to make sure IRQ_HANDLED was defined, presuming it's in use elsewhere, and I'm making minimal changes to the code. /* #ifndef IRQ_HANDLED */ #ifndef _LINUX_IRQRETURN_H 4. In osm_linux.c, I changed from the first line below to the second. /* SCpnt->result = ((DRIVER_INVALID|SUGGEST_ABORT)<<24) | (DID_ABORT<<16); */ SCpnt->result = ((DRIVER_INVALID|TASK_ABORTED)<<24) | (DID_ABORT<<16); Again, some defines are long gone. I chose TASK_ABORTED because it had the same hex value as SUGGEST_ABORT, 0x20, and seemed appropriate. Then it was cd into rr232x-linux-src-v1.8/product/rr232x/linux/, make clean, make, make install. The install does the depmod and modprobe. mark

But regardless of how much you care about my opinion, can you seriously say that you like the fact that the community of free users that helped take the Red Hat product from something that barely worked up to the fairly robust and usable 7.x version has been split into a set that favors stability using CentOS where there is really no way to contribute improvements and the wild and crazy fedora set that doesn't care about stability or maintaining compatible interfaces across versions. With the fedora set driving new development... -- Les Mikesell lesmikesell(a)gmail.com

Their product is support and not software. I think we all know that rebuilding SRPMS and development are different worlds but that doesn't mean that the community wouldn't come together to continue moving it forward. I know I'd try to help... The biggest challenge would be in developing the next major iteration but for a product already deep into its cycle like CentOS 6 it wouldn't be very difficult at all. It may shed a number of CentOS users on the front end, but a large number of them would come back.

CentOS6 bind DLV problems
by tony＠softins.co.uk 16 Aug '13

16 Aug '13

I have two CentOS6 boxes, both running Bind as a local resolver, with what appears to me to be the same configuration as each other. I have a problem on one but not the other, to do with DNSSEC Lookaside Validation. On the box with the problem, if I do: host www.bbc.co.uk 127.0.0.1 (for example), it sits there for a while, then gives me a timeout error. I did some tests while running a tcpdump packet capture on udp port 53, and I discovered that bind was fetching the correct answer normally, and then performing a validation query to one of the DLV servers at ISC (e.g. 199.6.0.29, 199.6.0.30, 199.6.1.29 or 199.6.1.30). It was not receiving any reply. After several seconds, it tried another DLV server and again received no reply. A similar test on the other box receives replies from ISC no problem. I have tried disabling iptables on the failing box, but that didn't help. I'm assuming something in the request causes ISC to ignore it. The relevant parts of named.conf are the same on both boxes, and are pretty close to the stock installation from CentOS6: //------------------------------------------------------------- options { listen-on port 53 { any; }; //listen-on-v6 port 53 { ::1; }; listen-on-v6 port 53 { none; }; directory "/var/named"; dump-file "/var/named/data/cache_dump.db"; statistics-file "/var/named/data/named_stats.txt"; memstatistics-file "/var/named/data/named_mem_stats.txt"; //allow-query { localhost; }; //allow-recursion { localhost; }; recursion yes; dnssec-enable yes; dnssec-validation yes; dnssec-lookaside auto; /* Path to ISC DLV key */ bindkeys-file "/etc/named.iscdlv.key"; managed-keys-directory "/var/named/dynamic"; }; logging { channel default_debug { file "data/named.run"; severity dynamic; }; }; zone "." IN { type hint; file "named.ca"; }; include "/etc/named.rfc1912.zones"; include "/etc/named.root.key"; //------------------------------------------------------------- I have compared named.iscdlv.key, named.root.key and named.rfc1912.zones, the they are the same on both systems. The key records stored in /var/named/dynamic are also the same on both. The failing box fails whether allow-query and allow-recursion are commented out or not. I can make it work by commenting out the dnssec lines, but of course that it just disabling the queries to ISC. Can anyone give me any ideas why one box would get DLV replies and the other would not? And hopefully how to fix it! Thanks! Tony -- Tony Mountifield Work: tony(a)softins.co.uk - http://www.softins.co.uk Play: tony(a)mountifield.org - http://tony.mountifield.org

samba: check password with AD without joining domain?
by Les Mikesell 16 Aug '13

16 Aug '13

Is there a way to get samba to authenticate against an AD without having to join that domain (which needs admin credentials)? I don't want any of the automatic user creation or mapping stuff from winbind, just a password check instead of having to maintain a local password. I can get that effect via kerberos for normal linux logins by using authconfig-tui, checking kerberos, and filling in the domain/kdc details. Local users still have to be added to the linux system, but where the user names match they can authenticate with their domain password. But, samba doesn't work that way. Even though the authconfig program modifies the smb.conf file, it doesn't seem to work without joining the domain. Is it possible to make it just authenticate via kerberos but otherwise use the local account details for the matching user? -- Les Mikesell lesmikesell(a)gmail.com

If I add priority=1 to [updates] in CentOS-Base.repo when I run "sudo yum update" I get the warning 66 packages excluded due to repository priority protections This does not seem to have any adverse effect, but what exactly does it mean? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 School of Mathematics, Trinity College, Dublin 2, Ireland

I could use debian, but then I'd have to learn to type apt-get instead of rpm. I'd prefer to continue using the commands that Red Hat baited us with. -- Les Mikesell lesmikesell(a)gmail.com

I guess I'd rather have seen the contributed work go to a distribution that didn't develop a community with a free version and then after accepting their work, take the free version away. CentOS still gives the same effect, so why didn't they just continue to allow redistribution? -- Les Mikesell lesmikesell(a)gmail.com
