  • Server freezes at XX:25

    - by Karevan
    We've ordered a 50 euro/month server on hetzner.de, it has debian OS. The problem is that server is freezing in random time of the day and nothing appears in log. Only hardware reboot helps. Part of the log file while it was freezing: Aug 17 22:38:26 Debian-60-squeeze-64-minimal pure-ftpd: ([email protected]) [INFO] New connection from 95.211.120.220 Aug 17 22:38:26 Debian-60-squeeze-64-minimal pure-ftpd: ([email protected]) [INFO] Logout.

No. theres no way to look in server's console right after when it freezes, sadly. Datacenter supporters do not really want to help about that. Server has been installed 30th july, times and dates of freezes are down there: 6 august, 0:25 18 august, 2:27 21 august, 1:25 26 august, 23:26. We decided that freezing around ??:25 isn't a hardware fault, and decided to reinstall the OS. Later, 31 august, our admin backed up all files, reinstalled Debian, and restored the backup. But then, 7 september, server went down again, at 5:05. We thought it was related to Anyone else experiencing high rates of Linux server crashes during a leap second day? and turned ntp off. But then the server went down twice again, 21 september, 17:29 and 24 september, 20:27. I called all linux admins I knew to help with solving it and they said everything is fine about configuring OS and it could be hardware only. But they dont know why it always freezes at XX:25-30. Maybe some of you know about something related to that?

  • Ubuntu 10.04 not detecting multiple monitors

    - by user28837
    I have 2 graphics cards, the output from the lspci: 01:00.0 VGA compatible controller: ATI Technologies Inc RV770 [Radeon HD 4850] 02:00.0 VGA compatible controller: ATI Technologies Inc RV710 [Radeon HD 4350] I have one monitor connected to the 4850 and 2 connected to the 4350. However when I go into System Preferences Monitors the only monitor shown is the one connected to the 4850. Is there something I need to enable for it to be able to use the other card? How do I get this to work. Thanks.

  • Interesting articles and blogs on SPARC T4

    - by mv
    Interesting articles and blogs on SPARC T4 processor   I have consolidated all the interesting information I could get on SPARC T4 processor and its hardware cryptographic capabilities.  Hope its useful. 1. Advantages of SPARC T4 processor  Most important points in this T4 announcement are : "The SPARC T4 processor was designed from the ground up for high speed security and has a cryptographic stream processing unit (SPU) integrated directly into each processor core. These accelerators support 16 industry standard security ciphers and enable high speed encryption at rates 3 to 5 times that of competing processors. By integrating encryption capabilities directly inside the instruction pipeline, the SPARC T4 processor eliminates the performance and cost barriers typically associated with secure computing and makes it possible to deliver high security levels without impacting the user experience." Data Sheet has more details on these  : "New on-chip Encryption Instruction Accelerators with direct non-privileged support for 16 industry-standard cryptographic algorithms plus random number generation in each of the eight cores: AES, Camellia, CRC32c, DES, 3DES, DH, DSA, ECC, Kasumi, MD5, RSA, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512" I ran "isainfo -v" command on Solaris 11 Sparc T4-1 system. It shows the new instructions as expected  : $ isainfo -v 64-bit sparcv9 applications crc32c cbcond pause mont mpmul sha512 sha256 sha1 md5 camellia kasumi des aes ima hpc vis3 fmaf asi_blk_init vis2 vis popc 32-bit sparc applications crc32c cbcond pause mont mpmul sha512 sha256 sha1 md5 camellia kasumi des aes ima hpc vis3 fmaf asi_blk_init vis2 vis popc v8plus div32 mul32  2.  Dan Anderson's Blog have some interesting points about how these can be used : "New T4 crypto instructions include: aes_kexpand0, aes_kexpand1, aes_kexpand2,         aes_eround01, aes_eround23, aes_eround01_l, aes_eround_23_l, aes_dround01, aes_dround23, aes_dround01_l, aes_dround_23_l.       Having SPARC T4 hardware crypto instructions is all well and good, but how do we access it ?      The software is available with Solaris 11 and is used automatically if you are running Solaris a SPARC T4.  It is used internally in the kernel through kernel crypto modules.  It is available in user space through the PKCS#11 library." 3.   Dans' Blog on Where's the Crypto Libraries? Although this was written in 2009 but still is very useful  "Here's a brief tour of the major crypto libraries shown in the digraph:   The libpkcs11 library contains the PKCS#11 API (C_\*() functions, such as C_Initialize()). That in turn calls library pkcs11_softtoken or pkcs11_kernel, for userland or kernel crypto providers. The latter is used mostly for hardware-assisted cryptography (such as n2cp for Niagara2 SPARC processors), as that is performed more efficiently in kernel space with the "kCF" module (Kernel Crypto Framework). Additionally, for Solaris 10, strong crypto algorithms were split off in separate libraries, pkcs11_softtoken_extra libcryptoutil contains low-level utility functions to help implement cryptography. libsoftcrypto (OpenSolaris and Solaris Nevada only) implements several symmetric-key crypto algorithms in software, such as AES, RC4, and DES3, and the bignum library (used for RSA). libmd implements MD5, SHA, and SHA2 message digest algorithms" 4. Difference in T3 and T4 Diagram in this blog is good and self explanatory. Jeff's blog also highlights the differences  "The T4 servers have improved crypto acceleration, described at https://blogs.oracle.com/DanX/entry/sparc_t4_openssl_engine. It is "just built in" so administrators no longer have to assign crypto accelerator units to domains - it "just happens". Every physical or virtual CPU on a SPARC-T4 has full access to hardware based crypto acceleration at all times. .... For completeness sake, it's worth noting that the T4 adds more crypto algorithms, and accelerates Camelia, CRC32c, and more SHA-x." 5. About performance counters In this blog, performance counters are explained : "Note that unlike T3 and before, T4 crypto doesn't require kernel modules like ncp or n2cp, there is no visibility of crypto hardware with kstats or cryptoadm. T4 does provide hardware counters for crypto operations.  You can see these using cpustat: cpustat -c pic0=Instr_FGU_crypto 5 You can check the general crypto support of the hardware and OS with the command "isainfo -v". Since T4 crypto's implementation now allows direct userland access, there are no "crypto units" visible to cryptoadm.  " For more details refer Martin's blog as well. 6. How to turn off  SPARC T4 or Intel AES-NI crypto acceleration  I found this interesting blog from Darren about how to turn off  SPARC T4 or Intel AES-NI crypto acceleration. "One of the new Solaris 11 features of the linker/loader is the ability to have a single ELF object that has multiple different implementations of the same functions that are selected at runtime based on the capabilities of the machine.   The alternate to this is having the application coded to call getisax(2) system call and make the choice itself.  We use this functionality of the linker/loader when we build the userland libraries for the Solaris Cryptographic Framework (specifically libmd.so and libsoftcrypto.so) The Solaris linker/loader allows control of a lot of its functionality via environment variables, we can use that to control the version of the cryptographic functions we run.  To do this we simply export the LD_HWCAP environment variable with values that tell ld.so.1 to not select the HWCAP section matching certain features even if isainfo says they are present.  This will work for consumers of the Solaris Cryptographic Framework that use the Solaris PKCS#11 libraries or use libmd.so interfaces directly.  For SPARC T4 : export LD_HWCAP="-aes -des -md5 -sha256 -sha512 -mont -mpul" .. For Intel systems with AES-NI support: export LD_HWCAP="-aes"" Note that LD_HWCAP is explained in  http://docs.oracle.com/cd/E23823_01/html/816-5165/ld.so.1-1.html "LD_HWCAP, LD_HWCAP_32, and LD_HWCAP_64 -  Identifies an alternative hardware capabilities value... A “-” prefix results in the capabilities that follow being removed from the alternative capabilities." 7. Whitepaper on SPARC T4 Servers—Optimized for End-to-End Data Center Computing This Whitepaper on SPARC T4 Servers—Optimized for End-to-End Data Center Computing explains more details.  It has DTrace scripts which may come in handy : "To ensure the hardware-assisted cryptographic acceleration is configured to use and working with the security scenarios, it is recommended to use the following Solaris DTrace script. #!/usr/sbin/dtrace -s pid$1:libsoftcrypto:yf*:entry, pid$target:libsoftcrypto:rsa*:entry, pid$1:libmd:yf*:entry { @[probefunc] = count(); } tick-1sec { printa(@ops); trunc(@ops); }" Note that I have slightly modified the D Script to have RSA "libsoftcrypto:rsa*:entry" as well as per recommendations from Chi-Chang Lin. 8.

  • Solaris X86 AESNI OpenSSL Engine

    - by danx
    Solaris X86 AESNI OpenSSL Engine Cryptography is a major component of secure e-commerce. Since cryptography is compute intensive and adds a significant load to applications, such as SSL web servers (https), crypto performance is an important factor. Providing accelerated crypto hardware greatly helps these applications and will help lead to a wider adoption of cryptography, and lower cost, in e-commerce and other applications. The Intel Westmere microprocessor has six new instructions to acclerate AES encryption. They are called "AESNI" for "AES New Instructions". These are unprivileged instructions, so no "root", other elevated access, or context switch is required to execute these instructions. These instructions are used in a new built-in OpenSSL 1.0 engine available in Solaris 11, the aesni engine. Previous Work Previously, AESNI instructions were introduced into the Solaris x86 kernel and libraries. That is, the "aes" kernel module (used by IPsec and other kernel modules) and the Solaris pkcs11 library (for user applications). These are available in Solaris 10 10/09 (update 8) and above, and Solaris 11. The work here is to add the aesni engine to OpenSSL. X86 AESNI Instructions Intel's Xeon 5600 is one of the processors that support AESNI. This processor is used in the Sun Fire X4170 M2 As mentioned above, six new instructions acclerate AES encryption in processor silicon. The new instructions are: aesenc performs one round of AES encryption. One encryption round is composed of these steps: substitute bytes, shift rows, mix columns, and xor the round key. aesenclast performs the final encryption round, which is the same as above, except omitting the mix columns (which is only needed for the next encryption round). aesdec performs one round of AES decryption aesdeclast performs the final AES decryption round aeskeygenassist Helps expand the user-provided key into a "key schedule" of keys, one per round aesimc performs an "inverse mixed columns" operation to convert the encryption key schedule into a decryption key schedule pclmulqdq Not a AESNI instruction, but performs "carryless multiply" operations to acclerate AES GCM mode. Since the AESNI instructions are implemented in hardware, they take a constant number of cycles and are not vulnerable to side-channel timing attacks that attempt to discern some bits of data from the time taken to encrypt or decrypt the data. Solaris x86 and OpenSSL Software Optimizations Having X86 AESNI hardware crypto instructions is all well and good, but how do we access it? The software is available with Solaris 11 and is used automatically if you are running Solaris x86 on a AESNI-capable processor. AESNI is used internally in the kernel through kernel crypto modules and is available in user space through the PKCS#11 library. For OpenSSL on Solaris 11, AESNI crypto is available directly with a new built-in OpenSSL 1.0 engine, called the "aesni engine." This is in lieu of the extra overhead of going through the Solaris OpenSSL pkcs11 engine, which accesses Solaris crypto and digest operations. Instead, AESNI assembly is included directly in the new aesni engine. Instead of including the aesni engine in a separate library in /lib/openssl/engines/, the aesni engine is "built-in", meaning it is included directly in OpenSSL's libcrypto.so.1.0.0 library. This reduces overhead and the need to manually specify the aesni engine. Since the engine is built-in (that is, in libcrypto.so.1.0.0), the openssl -engine command line flag or API call is not needed to access the engine—the aesni engine is used automatically on AESNI hardware. Ciphers and Digests supported by OpenSSL aesni engine The Openssl aesni engine auto-detects if it's running on AESNI hardware and uses AESNI encryption instructions for these ciphers: AES-128-CBC, AES-192-CBC, AES-256-CBC, AES-128-CFB128, AES-192-CFB128, AES-256-CFB128, AES-128-CTR, AES-192-CTR, AES-256-CTR, AES-128-ECB, AES-192-ECB, AES-256-ECB, AES-128-OFB, AES-192-OFB, and AES-256-OFB. Implementation of the OpenSSL aesni engine The AESNI assembly language routines are not a part of the regular Openssl 1.0.0 release. AESNI is a part of the "HEAD" ("development" or "unstable") branch of OpenSSL, for future release. But AESNI is also available as a separate patch provided by Intel to the OpenSSL project for OpenSSL 1.0.0. A minimal amount of "glue" code in the aesni engine works between the OpenSSL libcrypto.so.1.0.0 library and the assembly functions. The aesni engine code is separate from the base OpenSSL code and requires patching only a few source files to use it. That means OpenSSL can be more easily updated to future versions without losing the performance from the built-in aesni engine. OpenSSL aesni engine Performance Here's some graphs of aesni engine performance I measured by running openssl speed -evp $algorithm where $algorithm is aes-128-cbc, aes-192-cbc, and aes-256-cbc. These are using the 64-bit version of openssl on the same AESNI hardware, a Sun Fire X4170 M2 with a Intel Xeon E5620 @2.40GHz, running Solaris 11 FCS. "Before" is openssl without the aesni engine and "after" is openssl with the aesni engine. The numbers are MBytes/second. OpenSSL aesni engine performance on Sun Fire X4170 M2 (Xeon E5620 @2.40GHz) (Higher is better; "before"=OpenSSL on AESNI without AESNI engine software, "after"=OpenSSL AESNI engine) As you can see the speedup is dramatic for all 3 key lengths and for data sizes from 16 bytes to 8 Kbytes—AESNI is about 7.5-8x faster over hand-coded amd64 assembly (without aesni instructions). Verifying the OpenSSL aesni engine is present The easiest way to determine if you are running the aesni engine is to type "openssl engine" on the command line. No configuration, API, or command line options are needed to use the OpenSSL aesni engine.

  • Solaris X86 AESNI OpenSSL Engine

    - by danx
    Solaris X86 AESNI OpenSSL Engine Cryptography is a major component of secure e-commerce. Since cryptography is compute intensive and adds a significant load to applications, such as SSL web servers (https), crypto performance is an important factor. Providing accelerated crypto hardware greatly helps these applications and will help lead to a wider adoption of cryptography, and lower cost, in e-commerce and other applications. The Intel Westmere microprocessor has six new instructions to acclerate AES encryption. They are called "AESNI" for "AES New Instructions". These are unprivileged instructions, so no "root", other elevated access, or context switch is required to execute these instructions. These instructions are used in a new built-in OpenSSL 1.0 engine available in Solaris 11, the aesni engine. Previous Work Previously, AESNI instructions were introduced into the Solaris x86 kernel and libraries. That is, the "aes" kernel module (used by IPsec and other kernel modules) and the Solaris pkcs11 library (for user applications). These are available in Solaris 10 10/09 (update 8) and above, and Solaris 11. The work here is to add the aesni engine to OpenSSL. X86 AESNI Instructions Intel's Xeon 5600 is one of the processors that support AESNI. This processor is used in the Sun Fire X4170 M2 As mentioned above, six new instructions acclerate AES encryption in processor silicon. The new instructions are: aesenc performs one round of AES encryption. One encryption round is composed of these steps: substitute bytes, shift rows, mix columns, and xor the round key. aesenclast performs the final encryption round, which is the same as above, except omitting the mix columns (which is only needed for the next encryption round). aesdec performs one round of AES decryption aesdeclast performs the final AES decryption round aeskeygenassist Helps expand the user-provided key into a "key schedule" of keys, one per round aesimc performs an "inverse mixed columns" operation to convert the encryption key schedule into a decryption key schedule pclmulqdq Not a AESNI instruction, but performs "carryless multiply" operations to acclerate AES GCM mode. Since the AESNI instructions are implemented in hardware, they take a constant number of cycles and are not vulnerable to side-channel timing attacks that attempt to discern some bits of data from the time taken to encrypt or decrypt the data. Solaris x86 and OpenSSL Software Optimizations Having X86 AESNI hardware crypto instructions is all well and good, but how do we access it? The software is available with Solaris 11 and is used automatically if you are running Solaris x86 on a AESNI-capable processor. AESNI is used internally in the kernel through kernel crypto modules and is available in user space through the PKCS#11 library. For OpenSSL on Solaris 11, AESNI crypto is available directly with a new built-in OpenSSL 1.0 engine, called the "aesni engine." This is in lieu of the extra overhead of going through the Solaris OpenSSL pkcs11 engine, which accesses Solaris crypto and digest operations. Instead, AESNI assembly is included directly in the new aesni engine. Instead of including the aesni engine in a separate library in /lib/openssl/engines/, the aesni engine is "built-in", meaning it is included directly in OpenSSL's libcrypto.so.1.0.0 library. This reduces overhead and the need to manually specify the aesni engine. Since the engine is built-in (that is, in libcrypto.so.1.0.0), the openssl -engine command line flag or API call is not needed to access the engine—the aesni engine is used automatically on AESNI hardware. Ciphers and Digests supported by OpenSSL aesni engine The Openssl aesni engine auto-detects if it's running on AESNI hardware and uses AESNI encryption instructions for these ciphers: AES-128-CBC, AES-192-CBC, AES-256-CBC, AES-128-CFB128, AES-192-CFB128, AES-256-CFB128, AES-128-CTR, AES-192-CTR, AES-256-CTR, AES-128-ECB, AES-192-ECB, AES-256-ECB, AES-128-OFB, AES-192-OFB, and AES-256-OFB. Implementation of the OpenSSL aesni engine The AESNI assembly language routines are not a part of the regular Openssl 1.0.0 release. AESNI is a part of the "HEAD" ("development" or "unstable") branch of OpenSSL, for future release. But AESNI is also available as a separate patch provided by Intel to the OpenSSL project for OpenSSL 1.0.0. A minimal amount of "glue" code in the aesni engine works between the OpenSSL libcrypto.so.1.0.0 library and the assembly functions. The aesni engine code is separate from the base OpenSSL code and requires patching only a few source files to use it. That means OpenSSL can be more easily updated to future versions without losing the performance from the built-in aesni engine. OpenSSL aesni engine Performance Here's some graphs of aesni engine performance I measured by running openssl speed -evp $algorithm where $algorithm is aes-128-cbc, aes-192-cbc, and aes-256-cbc. These are using the 64-bit version of openssl on the same AESNI hardware, a Sun Fire X4170 M2 with a Intel Xeon E5620 @2.40GHz, running Solaris 11 FCS. "Before" is openssl without the aesni engine and "after" is openssl with the aesni engine. The numbers are MBytes/second. OpenSSL aesni engine performance on Sun Fire X4170 M2 (Xeon E5620 @2.40GHz) (Higher is better; "before"=OpenSSL on AESNI without AESNI engine software, "after"=OpenSSL AESNI engine) As you can see the speedup is dramatic for all 3 key lengths and for data sizes from 16 bytes to 8 Kbytes—AESNI is about 7.5-8x faster over hand-coded amd64 assembly (without aesni instructions). Verifying the OpenSSL aesni engine is present The easiest way to determine if you are running the aesni engine is to type "openssl engine" on the command line. No configuration, API, or command line options are needed to use the OpenSSL aesni engine. If you are running on Intel AESNI hardware with Solaris 11 FCS, you'll see this output indicating you are using the aesni engine: intel-westmere $ openssl engine (aesni) Intel AES-NI engine (no-aesni) (dynamic) Dynamic engine loading support (pkcs11) PKCS #11 engine support If you are running on Intel without AESNI hardware you'll see this output indicating the hardware can't support the aesni engine: intel-nehalem $ openssl engine (aesni) Intel AES-NI engine (no-aesni) (dynamic) Dynamic engine loading support (pkcs11) PKCS #11 engine support For Solaris on SPARC or older Solaris OpenSSL software, you won't see any aesni engine line at all. Third-party OpenSSL software (built yourself or from outside Oracle) will not have the aesni engine either. Solaris 11 FCS comes with OpenSSL version 1.0.0e. The output of typing "openssl version" should be "OpenSSL 1.0.0e 6 Sep 2011". 64- and 32-bit OpenSSL OpenSSL comes in both 32- and 64-bit binaries. 64-bit executable is now the default, at /usr/bin/openssl, and OpenSSL 64-bit libraries at /lib/amd64/libcrypto.so.1.0.0 and libssl.so.1.0.0 The 32-bit executable is at /usr/bin/i86/openssl and the libraries are at /lib/libcrytpo.so.1.0.0 and libssl.so.1.0.0.

    After upgrading to Precise, I am required to run 'sudo dhclient eth0' in a terminal in order to get the internet to work. Everything worked perfectly fine on Oneiric, so It's really puzzling me.

  • Why Does Ejabberd Start Fail?

    - by Andrew
    I am trying to install ejabberd 2.1.10-2 on my Ubuntu 12.04.1 server. This is a fresh install, and ejabberd is never successfully installed. The Install Every time, apt-get hangs on this: Setting up ejabberd (2.1.10-2ubuntu1) ... Generating SSL certificate /etc/ejabberd/ejabberd.pem... Creating config file /etc/ejabberd/ejabberd.cfg with new version Starting jabber server: ejabberd............................................................ failed. The dots just go forever until it times out or I 'killall' beam, beam.smp, epmd, and ejabberd processes. I've turned off all firewall restrictions. Here's the output of epmd -names while the install is hung: epmd: up and running on port 4369 with data: name ejabberdctl at port 42108 name ejabberd at port 39621 And after it fails: epmd: up and running on port 4369 with data: name ejabberd at port 39621 At the same time (during and after), the output of both netstat -atnp | grep 5222 and netstat -atnp | grep 5280 is empty. The Crash File A crash dump file is create at /var/log/ejabber/erl_crash.dump. The slogan (i.e. reason for the crash) is: Slogan: Kernel pid terminated (application_controller) ({application_start_failure,kernel,{shutdown,{kernel,start,[normal,[]]}}}) It's alive? Whenever I try to relaunch ejabberd with service ejabberd start, the same thing happens - even if I've killed all processes before doing so. However, when I killall the processes listed above again, and run su - ejabberd -c /usr/sbin/ejabberd, this is the output I get: Erlang R14B04 (erts-5.8.5) [source] [64-bit] [rq:1] [async-threads:0] [kernel-poll:false] Eshell V5.8.5 (abort with ^G) (ejabberd@ns1)1> =INFO REPORT==== 15-Oct-2012::12:26:13 === I(<0.478.0>:ejabberd_listener:166) : Reusing listening port for 5222 =INFO REPORT==== 15-Oct-2012::12:26:13 === I(<0.479.0>:ejabberd_listener:166) : Reusing listening port for 5269 =INFO REPORT==== 15-Oct-2012::12:26:13 === I(<0.480.0>:ejabberd_listener:166) : Reusing listening port for 5280 =INFO REPORT==== 15-Oct-2012::12:26:13 === I(<0.40.0>:ejabberd_app:72) : ejabberd 2.1.10 is started in the node ejabberd@ns1 Then, the server appears to be running. I get a login prompt when I access http://mydomain.com:5280/admin/. Of course I can't login unless I create an account. At this time, the output of netstat -atnp | grep 5222 and netstat -atnp | grep 5280 is as follows: tcp 0 0 0.0.0.0:5222 0.0.0.0:* LISTEN 19347/beam tcp 0 0 0.0.0.0:5280 0.0.0.0:* LISTEN 19347/beam ejabberdctl Even when it appears ejabberd is running, trying to do anything with ejabberdctl fails. For example: trying to register a user: root@ns1:~# ejabberdctl register myusername mydomain.com mypassword Failed RPC connection to the node ejabberd@ns1: nodedown I have no idea what I'm doing wrong. This happens on two different servers I have with identical software installed (really not much of anything). Please help. Thanks.

  • Network is not working anymore - Ubuntu 12.04

    Network is not working anymore - Ubuntu 12.04 Hello, I have a problem with my network connection. I have been using the same laptop with Ubuntu and the same connection for more than a year, and suddenly yesterday the connection stopped working (both wireless and wired). I've tested with another computer and the connection is fine (both wireless and wired). I've been reading similar posts but I haven't found a solution yet.

  • Wireless acting weird ubuntu 12.04 LTS

    I'm kinda new here, so please bear with me. My wireless driver is acting very weird. It shows my router's name, but when it is connecting (after entering the correct password), the icon on the tray is like, refreshing every once in a second, while showing the animation that it is connecting. And after a few seconds, error message come up saying that wireless network is disconnected. I installed the drive through "additional drivers". What info do you need?

  • Has any hobbyist attempted to make a simple VGA-graphics based operating system in machine code?

    - by Bigyellow Bastion
    I mean real bare bones, bare machine here(no Linux kernel, pre-existing kernel, or any bootloader). I mean honestly write the bootloading software in direct microarchitecture-specific machine opcode, host the operating system, interrupts, I/O, services, and graphical software and all hardware interaction, computation, and design entirely in binary. I know this is quite the leap here, but I was thinking to practice first in x86 assembly (not binary) 16-bit style. Any ideas?

  • VMWare Workstation 8 can't find the headers directory

    I'm having an issue with VMware Workstation 8. I installed it but when i run it, it shows this window: But, when I press on "Browse", this window comes up Even if I select the linux-headers-3.8.0-31-generic folder, it says that it can't find the C headers for that kernel. Why? P.S. I already tried sudo apt-get install linux-headers-3.8.0-31-generic and the terminal says that the kernel is up to date.

  • "mcp power or thermal limit exceeded" excessive in messages.log

    - by Stefan Thyberg
    I keep getting "mcp power or thermal limit exceeded" every five seconds while my computer is on, regardless of what it's doing. I googled it and found some Intel patches but I don't really know exactly what they do or how to apply them and I also don't want to patch my kernel with these random bits of code from some newsgroup. Can anyone shed some light on what exactly is going on and what the right fix is in this case? Am I better off just waiting for a kernel patch?

  • Some Oracle VM 3 updates

    - by wcoekaer
    Today we did another patch set update for Oracle VM 3 (3.0.3-build 227). This can be downloaded from My Oracle Support as patch ID 14736185. There are quite a few updates in here and I highly recommend any Oracle VM 3 customer or user to install this update. This patch can be installed on top of Oracle VM 3.0 versions 3.0.2 and 3.0.3. The patch is cumulative for 3.0.3. So if you already installed patch update 1 (3.0.3-150) then this will just be incremental on top of that and brings you to 3.0.3-build 227. There is a readme file which contains the patchlist in the patch info. The following patches are released on ULN for Oracle VM server 3.0 : initscripts-8.45.30-2.100.18.el5.x86_64 The inittab file and the /etc/init.d scripts. kernel-ovs-2.6.32.21-45.6.x86_64 The Linux kernel kernel-ovs-firmware-2.6.32.21-45.6.x86_64 Firmware files used by the Linux kernel osc-oracle-ocfs2-0.1.0-35.el5.noarch Oracle Storage Connect ocfs2 Plugin osc-plugin-manager-1.2.8-9.el5.3.noarch Oracle Storage Connect Plugin Infrastructure osc-plugin-manager-devel-1.2.8-9.el5.3.noarch Oracle Storage Connect Plugin Development ovs-agent-3.0.3-41.6.x86_64 Agent for Oracle VM xen-4.0.0-81.el5.1.x86_64 Xen is a virtual machine monitor xen-devel-4.0.0-81.el5.1.x86_64 Development libraries for Xen tools xen-tools-4.0.0-81.el5.1.x86_64 Various tooling for the manipulation of Xen instances Errata emails will be sent in the next few days with details on the above updates. Or you will find them here. I also did an update of my Oracle VM utilities to 0.4.0. They are also available from My Oracle Support, patch ID 14736239. These utils can be unzipped and installed on the server running Oracle VM Manager. Typically in /u01/app/oracle/ovm-manager-3/ovm_utils. There is a set of man pages in /u01/app/oracle/ovm-manager-3/ovm_utils/man/man8. There now are 6 commands : ovm_vmcontrol : VM level operations ovm_servercontrol : server level operations ovm_vmdisks : virtual disk/physical location mapping for VM disks ovm_vmmessage : message passing utility between the manager and the VM tools (in the Oracle VM templates) ovm_repocontrol : repository level operations ovm_poolcontrol : pool level operations Some of the new changes : at a pool level, acknowledge events and cascade to servers and virtual machines with outstanding events at a pool level, do a rescan of the storage for fibrechannel/iscsi disks if you add new devices (it does this operation then on every running server) at a repository level, fixup a device if it had a failed create repository at a repository level, refresh the repository and this will update the free space in the UI for ocfs2 repositories at a server level, acknowledge server events and cascade to virtual machines if needed at a VM level, acknowledge VM events at a VM level, bind vcpus to cores with vcpuset/vcpuget Please see the man pages and remember that these tools are just written As Is - no SRs... (per the documentation) Hopefully they are useful.

  • Insight into GNU/Linux boot process

    <b>Musing with GNU/Linux:</b> "In this document we will take a look at the different aspects of the boot process. Such as the BIOS which is the first code which runs, the boot loaders that can load different operating systems, pass arguments to the kernel, load it from different sources like a hard drive, a flash, and network & finally the kernel itself."

  • Empathy Audio Call Option Disabled 13.04

    - by PJ Singh
    Recently, I noticed that the Audio Call option is now disabled (greyed out) in Empathy when I right click on an available GoogleTalk contact. This option used to be available a few days ago. I do have libtelepathy-farstream3, libfarstream-0.1-0, and libfarstream-0.2-2 installed on Ubuntu 13.04 x64 with kernel 3.8.0-27. (Note, I just upgraded the kernel to 3.8.0-29 and still have this issue). Has anyone else experienced this recently, and if so, is there a resolution?

  • udev hide partition in nautilus for specific user/group

    - by user64780
    I'm trying to hide a partition form a specific group of users in Ubuntu 12.04. I have created a new rule in /etc/udev/rules.d/99-hide-disk.rules with KERNEL="sda3",ENV{UDISKS_PRESENTATION_HIDE}="1" And this works for all users. I tried KERNEL="sda3",ENV{UDISKS_PRESENTATION_HIDE}="1",GROUP="adm",MODE:="0700 but the partition is still hidden. That changes the group and permissions on the device rather than the rule. How do I make the rule only apply to a particular group of users?

  • 'dd' access to a drive

    - by John
    I've been working with making custom bootloader and kernel code (not necessarily Linux kernel). I'm putting the images on USB, and was using dd to place them on the sector they needed to be on, and I'm getting tired of burning the image to /dev/sda instead of /dev/sdb (effectively destroying my hard drive). So I was wondering if I could somehow give user access to the 'dd' command, but only to the /dev/sdb drive, so that if I accidentally type /dev/sda it won't let me, because I wouldn't have run the command as sudo or root.

  • Does an LTS desktop get any updates after three years?

    - by Oli
    In cleaning up an answer today, I noted the following: LTS desktops get updates for three years LTS servers get updates for five years An Ubuntu desktop is (essentially) a superset of server packages. So in the fourth and fifth year, if LTS Server gets Kernel updates*, are these also provided for LTS Desktop? What about other core-system stuff? I realise the Kernel is a little special because there is a -server variant but are updates pushed for -generic (et al) too?

  • After update, grub is broken.

    - by Bryan Allan
    Some months back I used wubi to install ubuntu on an hp laptop with vista. After not using it for a month or so, I loaded ubuntu and installed many updates (including kernel update). Windows boot manager loads without any problems, and I can boot to vista without problems. However, if I choose ubuntu, the screen briefly flashes Try (hd0,0) : NTFS5 and then goes to black. I never get to the kernel image selection screen.

  • Sempron 145 core unlocking

    - by Grant
    Call me a cheapskate looking for performance, but I have a Sempron 145 processor that has been unlocked to an Athlon II X2 4450e with a GIGABYTE GA-990FXA-UD3 motherboard, but only one of the two processor cores can be used at a time. If both of the cores are enabled in the BIOS the kernel will hang during boot, If I reboot the system and disable the second core (but not re-lock the processor), it will take me to the grub and then start normally. Is there a way to enable both cores and boot without kernel hangs?
