Forcing HDD spindown
by Christopher Svanefalk 02 Nov '11

02 Nov '11

Dear all, one problem I have on my system is the frequency with which the kernel winds up the HDD. It is hot almost constantly, and never seems to power down. Is there anything I can do (aside from deactivating updatedb and the like) in order to force the system to a minimal use of the HDD? Thanks in advance, Chris

I would say they are just different, not better or worse, though if you like a GUI package management tool, nothing beats "synaptic" on the ubuntu/debian family (I tend to prefer the command line tools since I use ssh to get to most systems and don't want to fool with remote X display, so for me it doesn't matter much if I use yum versus apt-get or rpm versus dpkg - it is just a question of sorting out all the command line options). -- users mailing list users(a)lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines

Re: Use of pam_exec or pam_smbpass

I meant the locations that allow changing a password, like in the Gnome preferences. I want to avoid the situation, where a user sees a password change option somewhere, that seems to work (it changes the Linux password), but causes problems later (Windows or Radius doesn't use the new password). That's why I hope to solve this on the PAM level somehow, so all programs that change passwords, will work completely. Telling the users to change their password on some web page, is not really an improvement over aliasing 'passwd' to the command needed to change the password, and telling them to only use that command, and not any other interface that offers to change a password.

my SysV daemons not starting on boot
by Michael D. Berger 02 Nov '11

02 Nov '11

In my new F15_64 box, my SysV daemons are not starting on boot, although I can start them with: /etc/init.d/myDaemon start (thanks to SYSTEMCTL_SKIP_REDIRECT). chkconfig --list myDaemon indicates start levels 3 and 5, and the links in /etc/rc.d are in place and correct. Debug indicates that the daemon function is being called. Also, the boot log says the daemon started. But the myDaemon log shows nothing, and ps -ef does not find it. I tried putting a sleep(1) at the start of myDaemon, but it didn't help. Thanks for your help. Mike. -- Michael D. Berger m.d.berger(a)ieee.org http://www.rosemike.net/

Use of pam_exec or pam_smbpass
by David Jansen 02 Nov '11

02 Nov '11

I'm trying to implement a custom password scheme through pam and samba. Basically, if a user wants to change their password on a client, the change has to be propagated to the samba server so it can also set the windows password. It works fine to tell users to use 'smbpasswd -r samba.mydomain', or to make passwd an alias that does that, but it would be better to make the change go through PAM so it will work from the GUI as well. Now, I found 2 ways to do this: pam_smbpass and pam_exec, but with both, I seem to be hitting a stone wall. pam_smbpass: On a machine that has a full smb.conf with all the LDAP connections etc (including ldap bind credentials in secrets.tbd), something like password required pam_smbpass.so nullok use_authtok try_first_pass in the appropriate /etc/pam.d files seems to do the trick. However, I don't really want to make every desktop a full member of the domain. So, it would be nice if there was a way to make pam_smbpass connect to a remote samba server, but I haven't been able to find one. Any help in this area would be appreciated. pam_exec: The man page states 'All module types (auth, account, password and session) are provided.' So it should be possible to write a script or prtogram to handle a pam password call, right? But, the script I wrote doesn't seem to receive the old or new password. And re-reading the documentation, I notice that nothing is mentioned about passing a password to the module anywhere, except on authentication, when expose_authtok will do that (then the password will be passed through stdin). But nothing like that when called for a password change. Again, what did I miss? Is the password module type not fully implemented, or should this be handles in another way? (OS: Fedora 15, RHEL 6, both same situation) David Jansen PS: I know a 3rd option would be to switch everything over to winbind, which may or may not work in our complex situation with various Windows domains with trusts. The point is: everything else works, except for a consistent password change method, so before we decide to redesign the whole setup, we want to be absolutely sure that there isn't something simple we are overlooking.

Packet loss problem and some questions related with OS
by Benjamin 02 Nov '11

02 Nov '11

Hi All, I have some doubts , please clear me. Query 1 ) should we set irq afinity of pci lan interface or onboard lan interface or we can do for both ? Query 2) H/w must be APIC enabled and for them only we can do set irq afinity , is it so? Query 3) What are the root cause for packet loss on interface ? Actually in one of my server , i m having strange result, i can not see any value update for lan interface in interrupts. cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 0: 124 0 0 78 IO-APIC-edge timer 1: 0 0 0 614 IO-APIC-edge i8042 8: 0 0 0 1 IO-APIC-edge rtc0 9: 0 0 0 0 IO-APIC-fasteoi acpi 12: 0 0 0 159 IO-APIC-edge i8042 19: 0 13411 0 0 IO-APIC-fasteoi ata_piix, ata_piix 21: 0 0 70 0 IO-APIC-fasteoi ehci_hcd:usb1 23: 0 0 32 0 IO-APIC-fasteoi ehci_hcd:usb2 40: 229974 0 0 0 HPET_MSI-edge hpet2 41: 0 85867 0 0 HPET_MSI-edge hpet3 42: 0 0 73987 0 HPET_MSI-edge hpet4 43: 0 0 0 106848 HPET_MSI-edge hpet5 45: 0 0 0 0 PCI-MSI-edge aerdrv, PCIe PME 46: 0 0 0 0 PCI-MSI-edge aerdrv, PCIe PME 47: 0 0 0 0 PCI-MSI-edge PCIe PME 48: 0 0 0 0 PCI-MSI-edge PCIe PME 49: 0 0 0 0 PCI-MSI-edge PCIe PME 50: 0 0 0 219714 PCI-MSI-edge 51: 10880 0 0 0 PCI-MSI-edge _ 52: 4 0 0 0 PCI-MSI-edge em1_ NMI: 44 16 8 29 Non-maskable interrupts LOC: 282 248 158 68 Local timer interrupts SPU: 0 0 0 0 Spurious interrupts PMI: 44 16 8 29 Performance monitoring interrupts IWI: 0 0 0 0 IRQ work interrupts RES: 6283 2718 2153 5353 Rescheduling interrupts CAL: 128 100 228 278 Function call interrupts TLB: 15 33 12 22 TLB shootdowns TRM: 0 0 0 0 Thermal event interrupts THR: 0 0 0 0 Threshold APIC interrupts MCE: 0 0 0 0 Machine check exceptions MCP: 78 78 78 78 Machine check polls ERR: 0 MIS: 0 em1 is my lan interface. ifconfig em1 Link encap:Ethernet HWaddr 00:25:90:0A:E6:A2 inet addr:192.168.100.152 Bcast:192.168.100.255 Mask:255.255.255.0 inet6 addr: fe80::225:90ff:fe0a:e6a2/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:216457 errors:0 _dropped:16064_ overruns:0 frame:0 TX packets:12715 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:36976063 (35.2 MiB) TX bytes:2391031 (2.2 MiB) _Interrupt:16_ Memory:fb5e0000-fb600000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) But i can not see any 16 irq no. in cat /proc/interrupts.

Problem seeing PDF files with firefox
by Timothy Murphy 02 Nov '11

02 Nov '11

Normally if I click on a link in firefox to a PDF file, I am asked if I want to see it or save it. But recently this has stopped working; if I click on such a file now, nothing happens. Eg, google just brought up the URL <http://www.ma.rhul.ac.uk/~uvah099/Maths/LinkingCosets4.pdf>, but when I click on this choice nothing happens - the screen remains blank. I have no problem retrieving the file with wget. Has anyone come across this problem? I'm running Fedora-15, which I keep updated. I see that I updated firefox a couple of days ago, which may be when the problem started: ------------------------------------- Oct 30 12:09:50 Updated: firefox-7.0.1-3.fc15.i686 ------------------------------------- Any advice or suggestions gratefully received. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
