[opensuse] 12.3 + ntfs + ext4 + USB3 + different copying speeds
by Basil Chupin 15 Apr '13

15 Apr '13

I bought a Seagate 2TB USB3 external HDD today and formatted 75% of it with ext4 file system and 25% with ntfs - using latest version of Gparted. My two internal 1TB Seagates are SATA 3 and formatted with ext4 except for one partition (ntfs) which has XP installed, but which is rarely used (it's mainly there to bring me back to earth and to remind me how bloody aweful Windows is). I use mc (Midnight Commander) 99.99% of the time to manage my files. After I formatted the external HDD (as described above) I went to copy files from my main system to the new external HDD - which is to be used for backups. What I found - and which is what I am now asking about - is that when, using mc, that when copying files to the *ext4* formatted partition the files where being copied across at ~80MB/s. The files copied over were a mixture of ntfs and ext4 files (which I had copied from a collapsing 32-bit system to my current *Linux* system last year when I replaced the old computer). However, when I went to copy files to the *ntfs* formatted part of the new external HDD, the best transfer rate I got was ~28MB/s - which looks very much like what I used to get when using USB2! So, why the *big* difference in transfer rates between copying files to a partition formatted in *ext4* and one formatted in *ntfs*?! What system am a I using? Look at my signature line; but I understand that some brain-dead mail clients drop the signature line so for these people with brain-dead mailers the sig. line is: Using openSUSE 12.3 x86_64 with KDE 4.10.1 & kernel 3.8.4-1 Any suggestions, please, as to why there is such a difference in the transfer rates between the 2 file systems, and how can this be overcome?

[opensuse] sssd getent shows only local users
by lynn 15 Apr '13

15 Apr '13

12.3 client connected to AD Hi I have sssd up and running against a Samba4 AD. It works fine. The only quirk is that getent passwd and getent group return only local users getent passwd lynn2 and getent group Domain\ Users work fine however getent passwd lynn2 lynn2:*:3000033:20513:lynn2:/home/users/lynn2:/bin/bash getent group 'Domain Users' Domain Users:*:20513: If I set enumerate = true in sssd.conf Then, getent passwd and getent group return as expected: both local and domain objects. But only the first time that the commnds are run. I believe that the enumerate line should allow me list all domain users too. Is it possible to get all the objects listed always with getent under sssd? /etc/nsswitch.conf passwd: compat sss group: compat sss /etc/sssd/sssd.conf [sssd] services = nss, pam config_file_version = 2 domains = default [nss] [pam] [domain/default] access_provider = simple #simple_allow_users = myuser enumerate = false cache_credentials = True id_provider = ldap auth_provider = krb5 chpass_provider = krb5 krb5_realm = HH3.SITE krb5_server = hh16.hh3.site krb5_kpasswd = hh16.hh3.site ldap_uri = ldap://hh16.hh3.site/ ldap_search_base = dc=hh3,dc=site ldap_tls_cacertdir = /usr/local/samba/private/tls ldap_id_use_start_tls = False ldap_default_bind_dn = cn=lynn2,cn=Users,dc=hh3,dc=site ldap_default_authtok = xx ldap_default_authtok_type = password ldap_user_object_class = person ldap_user_name = samAccountName ldap_user_uid_number = uidNumber ldap_user_gid_number = gidNumber ldap_user_home_directory = unixHomeDirectory ldap_user_shell = loginShell ldap_group_object_class = group #ldap_user_search_filter =(&(objectCategory=User)(uidNumber=*)) -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Clone monitors on two separate cards
by Branislav Klocok 14 Apr '13

14 Apr '13

Hello Guys, I have a ThinkPenguine notebook running on OpenSuSe 12.3. and last week I have bought Plugable USB docking station (runs with DysplayLink chipset). The aim of this purchase was getting this behavior: 1. Running two cloned screens when connected to USB docking station 2. Running primary screen on the external monitor and extended screen on the notebook, when connected to USB docking station. Basically both options would be fine. After making the adjustments to X server suggested here http://plugable.com/2011/12/23/usb-graphics-and-linuxI got the external monitor working more ore less OK. Never the less my laptop screen was not functional. I have tried to manually edit xorg.conf in following way: Section "Device" Identifier "laptop_card" driver "intel" BusID "PCI:0:2:0" EndSection Section "Device" Identifier "uga" driver "fbdev" Option "fbdev" "/dev/fb1" Option "ShadowFB" "off" EndSection Section "Monitor" Identifier "uga_monitor" EndSection Section "Monitor" Identifier "laptop_monitor" EndSection Section "Screen" Identifier "uga_screen" Device "uga" Monitor "uga_monitor" EndSection Section "Screen" Identifier "laptop_screen" Device "laptop_card" Monitor "laptop_monitor" EndSection Section "ServerLayout" Identifier "Default Layout" Screen 0 "uga_screen" 0 0 Screen 1 "laptop_screen" RightOf "uga_screen" Option "Xinerama" "On" EndSection But unfortunately the result is the same. If I start X with usb plugged in, my laptop screen disappears. Any ideas? -- Branislav Klocok email: branislav.klocok(a)orava.sk skype: b_r_k_o tel_sk: +421908703366 tel_ch: +41786888545 -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] 12.3 installation, runlevels and trouble shooting
by Bruce Ferrell 14 Apr '13

14 Apr '13

OK gang, I get it new and shiny is kool. This, however, is ridiculous. Booting from install media puts my Dell XPS 1730 (aka Dell MXG071) w/Nvidia GeForce 8700M GT into display test mode (pretty colors on the LCD but not very compute useful), unless I use failsafe mode... And after install all I have is x11failsafe and a VERY slow system. Systemd doesn't seem to allow me to switch to what used to be runlevel 3 (does such a thing still exist in a port systemd world?) to even begin to troubleshoot. Open a bug? Sure, where to start? What exactly is broken? You tell me, where do I start. BTW, I am NOT a windows/OS X refugee. I've been doing this a very long time. 12.3 is a mess at best! -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] firewall/iptables suggestion for preventing brute-force SIP attempts?
by Per Jessen 13 Apr '13

13 Apr '13

Our asterisk server is seeing numerous brute force attempts to get access to a SIP account. I've tried setting up a 'prevent flood' config with iptables, but wihtout much success. fail2ban et al does not work, so I was hoping someone might have a hint wrt an iptables setup to stop such brute force attacks? thanks Per -- Per Jessen, Zürich (4.4°C) http://www.dns24.ch/ - free DNS hosting, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

Um.. you call that splash? I call it messed up output... you say half dozen, I say 6? ;-) It tries to load a frame buffer on my crap, on-board, video card which, with VGA compatibility, doesn't do so well and can, at best do 1280x1024 in 32 bit (on a 16:9 display that came with it! ;-)); To run in 1920x1080 it needs to drop down to 16bit color). It wasn't meant to do graphics. It's outfitted to be run as a server. Same CPU does go in my desktop but there it has graphics (but not much disk space). Only in 12.3 and later have I gotten the half screen -- but that's partly because my card now has a kernel adapter that matches it -- I don't know what mode the half-screen is...maybe it's trying 1920x1080 in 32 bit to match the monitor? Just a guess.. I try not to boot in a graphics or framebuffer mode, usually. It eats memory for a console that isn't going to be used very often. That's what you get when I boot from initrd or if I let it set my console font: a frame buffer that runs slowly with no HW acceleration. Vs. Running in VGA text mode, and it uses HW scrolling @ about 10X the speed (not that either is readable in any detail, but the frame buffer scroll creates a motion blur as a it scrolls up on my screen, whereas the HW scroll does not , though it goes by too fast for anything other than catching anomalies or errors. It doesn't have to switch mode so the graphics monitor never loses sync -- so no missed output during a mode switch. Scrolling is offloaded to the video controller. If it stayed in VGA mode, it wouldn't need to waste memory allocating a frame buffer nor waste cpu resources doing the software scrolling that a frame buffer requires (not that it's alot of memory or cpu, but it's still wasted). > -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Systemd, batch files, tomcat and webapps
by John Connor 12 Apr '13

12 Apr '13

Background: I run a small school server in Kolin in the Czech Republic. The server is running OpenSUSE 12.2, 32 bits. I was asked to install a webapp (OLAT, Online Learning and Teaching, by the University of Zurich). This was our first webapp, so I installed Tomcat 7 and the JDK, then OLAT. Tomcat worked without problems, and all the webapps bundled with Tomcat also work. OLAT, however, refused to deploy. To cut a long story short, I discovered that OLAT would deploy and functioned correctly only when Tomcat was NOT launched using systemd. If I launched Tomcat via the command line, using batch files not registered with systemd, everything was OK. But using Yast runlevel editor to launch Tomcat somehow invokes systemd, and then OLAT will not deploy. This presented me with the problem of how to start Tomcat after a reboot, since I couldn't use the run-level editor and if I understand correctly inittab is also not available under systemd. In the end I used a fairly horrible hack - I used an @reboot tag in the root crontab. This restarts Tomcat on reboot without involving systemd directly, and everything works. My users are happy, but I'm not. Several questions: 1) does anybody have any explanation for this bizarre behaviour? 2) Why is the execution of some batch files (in this case /etc/init.d/tomcat) intercepted by systemd, while the execution of others is not? How can I break this link? (renaming the tomcat.service file didn't make any difference) 3) If I want to start something at or shortly after boot without using systemd, is there an "official" way to do it? I thought the problem might lie in some difference in the environment between a command-line launch and a systemd launch, so I duplicated the commandline environment using printenv > file, then used <file> in an EnvironmentFile directive in the tomcat.service file. It made no difference. I don't want to get into the systemd is better/worse than systemV debate, but I will observe that the way systemd "takes over" some batch files made debugging much more difficult. That may be just my ignorance talking. Thanks for any help John Connor -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

Okay thanks for the explanation. It's a lot clearer now. I'm inclined to hold out for the moment and hope for a bug fix, else I end up with changed configurations and issues I've forgotten all about months down the line.
