reply-to-list vs. reply-all [WAS Re: [opensuse] zypper]

Several are mandatory reply all (lkml and its siblings). Some are reply-all desired (opensuse-kernel, opensuse-project, and few more in this family.) Mostly these are ones where the serious developers hang out. They like reply-all for reasons I won't go into. Most lists are indifferent. And then there is opensuse(a)opensuse.org. It's netiquette here that it be "reply to list" only. I've for years tried to remember that it is special, but at this point I'm no longer willing to try. So you have 2 choices. 1) Accept I'm a pain in your behind and get past it. 2) Ask me to blackball your posts so I won't answer them again. You'll probably want to blacklist me in turn so you don't waste energy answering some question of mine. ==> others I know Ken's not the only one who dislikes it when people reply-to-all. Feel free to ask me to blackball your posts from my inbox as well. Greg -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Need help with systemd

by Lew Wolfgang

Hi Folks, On a fresh install of 64-bit 12.1 I decided to try sshguard instead of the block-hosts package I've been using for years. sshguard was installed from the security repository. After fiddling with /etc/init.d/sshguard and /etc/sysconfig/sshguard I managed to get it working. The big problem was the iptables entry to allow ssh appeared before the sshguard entry. But now it doesn't work on bootup. The changes sshguard makes to iptables are overwritten by a subsequent process. If I run "/etc/init.d/sshguard restart' after the system is up in runlevel 5 everything is fine. So I need to figure out how to delay sshguard so that it appears later in the boot sequence. Would it be as simple as changing the order of the entries in /etc/init.d? Does anyone know how to do this right in a default systemd system? I don't want to experiment too much because the system is remote (Vancover) and the KVM/IP thing doesn't work with SuSE. (that's a matter for a later date) Thanks, Lew -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] nfs and windows acl woes

by lynn

Original of a post sent to samba(a)lists.samba.org. It would be great if anyone here could help too. <quote> Hi everyone We're really struggling with nfs4 <--> windows acls. Scenario Samba4 share --> cifs --> win7. Samba4 share --> nfs4 --> Linux. win7 <--> Linux acl's not inherited e.g. It is not possible to create files with group rw on a umask 0022 nfs4 share. nfs4_setfacl cannot override umask. Using POSIX or windows acls this works fine. I've approached the nfs4 devs and they've said that they'll look into it, but so far. Exporting nfs4 with -o noacl (in the hope that the windows acl would take effect) has no effect. 1. Is it possible to get Samba to override the nfs4 acl and use whatever I've set on windows security acl instead? Or vica versa? 2. Is there a way to export a single directory with a umask of my choice? 3. Would it be reasonable to ask my distro (openSUSE) to consider this problem as a feature request? Perhaps as a patch over nfs4_setfacl? Thanks, L & S at lcb </quote> Salu2 L x -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] TBird icon

by Robert Benjamin

When I set up open Suse v 11.10 as a Newbie I somehow got all the icons on the desktop I wanted except for Thunderbird, It is there at the top left in the sidebar(windows) and in the Applications box. But it won't let me drag it to the desktop to keep it there. Can anyone help? Thanks.

[opensuse] destructor in LD_PRELOADed *.so file not run on SuSE

by Bernhard Voelker

In the GNU coreutils project, there was a discussion about a new test which uses a destructor in an *.so file loaded into program space via LD_PRELOAD: http://lists.gnu.org/archive/html/coreutils/2012-02/msg00173.html However, the destructor is not run on OpenSuSE (nor on SLES10.x btw.), but works fine on other systems (e.g. Redhat). This is Jim's commit: http://git.savannah.gnu.org/cgit/coreutils.git/commit/?id=b29db6767612cf70e… Attached is the relevant C code which intercepts the system calls getxattr() and lgetxattr(). The number of calls is counted and should be stored in a file "x" by the destructor print_call_count(): void __attribute__ ((destructor)) print_call_count (void); Compile / link it: $ gcc -fPIC -O2 -c k.c $ ld -G k.o -o k.so Run it: $ LD_PRELOAD=./k.so ls --color=always -l . Now, the file "x" should be created, but it isn't. (How) are LD_PRELOADed destructors disabled on SuSE? Ah, yes - I'm running this: $ head -n 1 /etc/SuSE-release openSUSE 12.1 (x86_64) $ gcc --version | head -n 1 gcc (SUSE Linux) 4.6.2 $ uname -rvmspio Linux 3.1.9-1.4-desktop #1 SMP PREEMPT Fri Jan 27 08:55:10 UTC 2012 (efb5ff4) x86_64 x86_64 x86_64 GNU/Linux Have a nice day, Berny

[opensuse] intermittent wireless connection drops

by Fr David Ousley

We're having trouble with dropped wireless connections from a laptop. It connects when laptop is booted, and then stays on for an hour or three or six hours, and then is lost. Then in manually reconnecting, one of two things shows up. Sometimes, Network Manager shows "activating", which is usually that it has connected to the router but has not been able to get a network address. This can usually be fixed by going into the Network Manager, and reentering the password (or one character of it). Other times, if one "scans" in network manager, no networks appear. In this case, "rcnetwork restart" will usually restore the connection. So the problem is not that we cannot connect, but that once we connect it is not reliable, and gets dropped at unpredictable intervals, usually but not always once or twice a day. I'm using knetworkmanager in kde (rather than ifup), but the same behavior has occurred in gnome. If I recall, it has also happened with ifup. Opensuse 11.4, kde 4.6. Any suggestions as to how to troubleshoot this?

[opensuse] Grub security doubt

by PM

Hi, I have erncrypted the password for increased security, executed the command 'grub-md5-crypt' in a shell (as root). One will be asked for the password. After the password is entered, it will be displayed in encrypted form: linux:~ # grub-md5-crypt Password: Retype password: $1$xmY1P/$wL6rbH2VC2L5IT8GivtytyeLq. I appended this string ('$1$xmY1P/$wL6rbH2VC2L5IT8GivtytyeLq') to the global section of the file '/boot/grub/menu.lst'. The option that needs to be appended is 'password --md5'. The section looked as follows: ********** # Modified by YaST2. Last modification on Tue Jan 17 18:55:10 IST 2012 # THIS FILE WILL BE PARTIALLY OVERWRITTEN by perl-Bootloader # Configure custom boot parameters for updated kernels in /etc/sysconfig/bootloader default 0 #timeout 8 password --md5 $1$xmY1P/$wL6rbH2VC2L5IT8GivtytyeLq. ##YaST - generic_mbr gfxmenu (hd0,0)/boot/message ##YaST - activate ........................ ........................ ********** So now, when I boot into the PC, I have to press 'p' and enter the password and this is what which is expected. But when logging in _when_ I don't press 'p' (to enter the password and boot) but only long press Enter, I get booted, so why the above option (of appending the grub-md5 password to the global section of '/boot/grub/menu.lst' file) is not working in this particular case? Since implementing the above should block both - the normal logging (until password is entered) and interactive editing too.

Re: [opensuse] cloning a drive?

by michael＠actrix.gen.nz

If you are going to use rsynce consider that you may want to use some additional options to make the copy more faithful to the original... rsync -a -H -A -X -S /from/ /to/ See the man page. Before going to 12.1 I used rsync to duplicate / to a spare partition (I always leave make two OS partitions on every drive - can't have too many now that disk is cheap). I then manually edited /etc/fstab /boot/grub/menu.1st to make sure it would boot, that way I could boot the upgraded 12.1 or the old 11.4. Note this was in addition to offline backups (also using rsync). If you brought a machine down to runlevel 1 it would be reasonably safe to just rsync the live machine.

[opensuse] CLOCK_THREAD_CPUTIME_ID or glibc broken?

by Christoph Bartoschek

Hi, consider the following program: #include <iostream> extern "C" { #include <time.h> } int main() { struct timespec start, stop; clock_gettime(CLOCK_THREAD_CPUTIME_ID, &start); sleep(7); clock_gettime(CLOCK_THREAD_CPUTIME_ID, &stop); std::cout << "Runtime: " << ((stop.tv_sec - start.tv_sec) + 1e-9*(stop.tv_nsec - start.tv_nsec)) << "\n"; } On Opensuse 12.1 this prints about 14 seconds. On Ubuntu or RHEL I get something around 1e-5 as expected. Is this a bug in the glibc shipped with Opensuse 12.1?
