  • checking the status of CPU throttling: whether ON or OFF

    - by Gaurish Telang
    I am trying to install the ATLAS BLAS library which recommends that I turn if CPU throttling to do the install. How do I check if my CPU throttling is ON or OFF? I tried the suggestion of Code: ./cpufreq-selector -g performance in the /usr/bin directory as suggested elsewhere in the forum but there was no output and the control returned back to the user. I have searched everywhere but there does not seem to be a way to determine the status of the CPU throttling

  • Java update "Failed to download required installation files."

    - by therefromhere
    On my Windows 7 machine the Java update consistently fails with this error message. This seems to a common problem, does anyone have an insight into what's going wrong, and is there a fix for it other than either disabling the update check (seems a bad idea from a security point of view) or waiting for the nag message and then manually installing the new version (annoying and stupid from a usability point of view). Note that I did install the previous version manually (updating from 6.23 to 6.30 I think?), thinking that might resolve the issue, but no luck.

  • Why does my MacBook Pro trackpad sometimes set its tracking speed to slow, all by itself?

    - by Paul D. Waite
    Every now and then, the trackpad on my MacBook Pro will seem to set its own tracking speed to slow. I’ll notice that the cursor is moving slowly, and when I check in System Preferences, the tracking speed is indeed at slow, even though I never set it to slow myself. This might happen before/after switching into a VMWare virtual machine, but I’m not sure. It doesn’t seem to happen on startup or anything, just during use. Anyone else seen this?

  • Authenticate by libpam-mysql and libnss-mysql (CentOS)

    - by Chris
    I'm trying to get MySQL to function as a backend for authenticating users on CentOS 6.3. So far I have successfully installed and configured libnss-mysql. I can test this by doing: # groups testuser testuser : sftp Testuser is a member of the sftp group in fact, all MySQL based useraccounts will be hardcoded to it. The sftp group is chrooted and forced to use internal-sftp so they cannot do anything but access their home directory. Then I configured pam-mysql and PAM to allow mysql logins. This also works.. When SELinux is not enforcing. When I do setenforce 1 users can no longer login. Error: Permission denied, please try again. This is my pam_mysql.conf file: users.host=localhost users.db_user=nss-pam-user users.db_passwd=*********** users.database=sftpusers users.table=users users.user_column=username users.password_column=password users.password_crypt=6 verbose=1 My /etc/pam.d/sshd: #%PAM-1.0 auth sufficient pam_sepermit.so auth include password-auth auth required pam_mysql.so config_file=/etc/pam_mysql.conf account sufficient pam_nologin.so account include password-auth account required pam_mysql.so config_file=/etc/pam_mysql.conf password include password-auth # pam_selinux.so close should be the first session rule session required pam_selinux.so close session required pam_loginuid.so # pam_selinux.so open should only be followed by sessions to be executed in the user context session required pam_selinux.so open env_params session optional pam_keyinit.so force revoke session include password-auth And to be complete the contents of some log files.. /var/logs/secure Nov 20 14:52:20 hostname unix_chkpwd[4891]: check pass; user unknown Nov 20 14:52:20 hostname unix_chkpwd[4891]: password check failed for user (testuser) Nov 20 14:52:20 hostname sshd[4880]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=192.168.10.107 user=testuser Nov 20 14:52:22 sftpusers sshd[4880]: Failed password for testuser from 192.168.10.107 port 51849 ssh2 /var/logs/audit/audit.log type=USER_AUTH msg=audit(1353420107.070:812): user pid=5285 uid=0 auid=500 ses=24 subj=unconfined_u:system_r:sshd_t:s0-s0:c0.c1023 msg='op=pubkey acct="testuser" exe="/usr/sbin/sshd" hostname=? addr=192.168.10.107 terminal=ssh res=failed' type=USER_AUTH msg=audit(1353420112.312:813): user pid=5285 uid=0 auid=500 ses=24 subj=unconfined_u:system_r:sshd_t:s0-s0:c0.c1023 msg='op=PAM:authentication acct="testuser" exe="/usr/sbin/sshd" hostname=192.168.10.107 addr=192.168.10.107 terminal=ssh res=failed' type=USER_AUTH msg=audit(1353420112.456:814): user pid=5285 uid=0 auid=500 ses=24 subj=unconfined_u:system_r:sshd_t:s0-s0:c0.c1023 msg='op=password acct="testuser" exe="/usr/sbin/sshd" hostname=? addr=192.168.10.107 terminal=ssh res=failed' I tried to let audit2why explain the problem but it remains silent even though there are some errors. Does anyone see the problem? Thanks! EDIT: Turns out it's almost working with setenforce 0 I can mkdir foobar but if I do a single ls I get an error: Received message too long 16777216

  • How do I integrate GPG with alpine?

    - by Thomas
    I have tried a couple of howtos, but they seem to either be too out of date or just plain don't work (don't work for me, at least). How do I sign and encrypt messages, as well as check integrity of received messages (and decrypt them if needed) in pine/alpine? I tried pipeing (with "|") but the terminal doesn't seem to cooperate so that I can provide my passphrase.

  • PXE Booting with 2 NICs not finding DHCP server

    - by Xaver
    I have two NICs in a client PC. I have a WDS server. When I boot from PXE on client computer I receive: WdsClient: An error occurred while obtaining an IP address from the DHCP server. Please check to ensure that there is an operational DHCP server on this network segment. I think my client is trying to get an IP adress from the NIC which not connected to LAN. How to avoid this error?

  • System hangs after IncreaseUserVa change on Windows 7 64-bit

    - by imriss
    By mistake, I applied the IncreaseUserVa 3072 on a Windows 7 64-bit: BCDEDIT /set IncreaseUserva 3072 After that, the system is getting hanged when I start an intensive Matlab code. I tried to revert the change using both: BCDEDIT /set increaseUserva 2048 or BCDEDIT /deletevalue increaseUserva But, I get to the same problem when I run the Matlab code. When I check bcdedit/enum all, it does not contain increaseUserva, after /deletevalue command. Any idea?

  • Com port redirection from Windows 7 to Windows Server 2008 R2

    - by Ola Eldøy
    We use "Copy file.prn to \tsclient\com1" to print from a TS session to a locally attached serial printer. This works fine from Windows XP, but when trying it from a Windows 7 client computer, we get an "Access is denied" error message. And yes, the check box of COM port is selected on the Local Resources tab of the Remote Desktop Connection client. Any pointers? Has anyone even managed to do this successfully?

  • Avoid read-write access to bad sectors on HDD to continue working on the HDD

    - by goldenmean
    I have a HP Pavilion dv6446 notebook. It had Windows Vista Home premium. After 4.5+ years of usage, just recently it started malfunctioning. While working fine, its screen goes white or sometimes some thin black lines horizontally. Laptop freezes. Hard reboot works. Again it works for some 2 hrs or so, same error. To diagnose I did run the Memory and Hard disk check which is present in the Bios Setup. Memory test passed. Hard disk test returned an error saying something like - "Replace the hard disk". Bad.. Some sectors or platters have gone bad on the disk. (I confirmed this later by further tests mentioned below) Then I tried installing a Ubuntu 11.10. It listed 3 partitions /dev/sda1, sda2, sda2. It again gave error and could not install grub loader on /dev/sda1. Bad sectors. Then redid the Ubuntu installation, this time asked to to install the Ubuntu on /dev/sda3. and kept /dev/sda1 for /home. Installed fine, and works fine as well. Due to unavailability of WiFi/ Ethernet driver for that adapters under Ubuntu( at least I could not configure them and get the networking working at all), I decided to go back to reinstall windows Vista. It did install fine. I did not have to format one data partition which has my data. I just formatted one partition which installed Windows So in effect HDD has not undergone a full format here. Worked ok for 1 day. But same white screen and freeze happened. Looks like while it is in use, it accesses the bad sectors for storing some data and that's when it bombs. I am inclined to think HDD has not failed fully or crashed but has developed bad sectors. Else if it was a HDD crash, it would have refused to boot at all let alone install on it. Questions: Is there any HDD test check under windows or any such tools windows/linux based ewhere which can identify the bad sectors of the HDD and 'lock/isolate' them from further read-write access of any kind. If not what are my options, if any to salvage this laptop HDD without replacing it. EDIT: Would the Disk Error checking tool under windows help in any way?
