  - by ant2009

  I am using Fedora 12, with kernel stv-fedora 2.6.31.12-174.2.22.fc12.i686 I have install VirtualBox OSE v3.1.4-1.fc12. When I start VirtualBox I get the following error: Failed to start the virtual machine WinXP32. Failed to open/create the internal network 'HostInterfaceNetworking-eth0' (VERR_SUPDRV_COMPONENT_NOT_FOUND). One of the kernel modules was not successfully loaded. Make sure that no kernel modules from an older version of VirtualBox exist. Then try to recompile and reload the kernel modules by executing '/etc/init.d/vboxdrv setup' as root (VERR_SUPDRV_COMPONENT_NOT_FOUND). However, if I run /etc/init.d/vboxdrv setup I get this error: -bash: /etc/init.d/vboxdrv: No such file or directory How do I get rid of the error and run VirtualBox?

• Specify IPSEC port range using ipsec-tools

  - by Sandman4

  Is it possible to require IPSEC on a port range ? I want to require IPSEC for all incoming connections except a few public ports like 80 and 443, but don't want to restrict outgoing connections. My SPD rules would look like: spdadd 0.0.0.0/0 0.0.0.0/0[80] tcp -P in none; spdadd 0.0.0.0/0 0.0.0.0/0[443] tcp -P in none; spdadd 0.0.0.0/0 0.0.0.0/0[0....32767] tcp -P in esp/require/transport; In setkey manpage I see IP ranges, but no mention of port ranges. (The idea is to use IPSEC as a sort of VPN to protect internal communications between multiple servers. Instead of configuring permissions basing on source IPs, or configuring specific ports, I want to demand IPSEC on anything which is not meant to be public - I feel it's less error-prone this way.)

• dynamic routing between openvpn tunnels

  - by pQd

  i'm thinking about using dynamic routing [ OSPF or RIP ] via OpenVPN tunnels. right now i have few offices connected in full mesh, but this is not scalable solution as we add more locations. i would like to avoid situation when plenty of internal traffic is affected if one of two vpn termination points that i plan to use is down. do you have similar configuration working in production? if so - what routing daemon did you use - quagga? something else? did you encounter any problems? thanks!

• Understanding Linux SCSI queue depths

  - by Troels Arvin

  I'm experimenting with the effects of different SCSI queue depth values on a Dell server running CentOS Linux 5.4 (x86_64). The server has two QLogic QLE2560 FC HBAs connected via multipathing to a storage system. The storage system has allocated two LUNs to the server, each connected through four paths in an active-active-active-active round-robin configuration. All in all, the two LUNs exist as eight /dev/sdX devices, represented by two devices in /dev/mpath. I currently adjust the queue depth values in /etc/modprobe.conf and check the result (after rebooting) by looking in the seventh column of /proc/scsi/sg/devices. Two questions related to that: Is there a way to adjust queue depths without rebooting or unloading the qla2xxx kernel module? E.g., can I echo a new queue depth value into some /proc or /sys-like file to update the queue depth? If I set the queue depth to 128, is that 128 in total for all devices handled by the qla2xxx module?, or 128 for each HBA? (256 in total), or 128 for each of the eight /dev/sdX devices (1024 in toal)?, or 128 for each of the two /dev/mpath/... devices (256 in total)? This is important for me to know so that my server doesn't flood the storage system, affecting other servers connected to it.

• How to roll-your-own live CD for safe home browsing

  - by user36533

  Hi, I'm interested in booting-off-flash (i.e. like livecd) for more secure online banking at home. -I like system rescue CD, but AFAIK it doesn't have the wifi drivers. (These are convenient) -ubuntu live cd has the wi-fi drivers, but also has a lot of stuff I don't need -I'd like a way to save some basic config settings (e.g. wifi SSID and passphrase), so that wifi works upon startup, i.e. without having to re-enter the settings. What's the best way to 'roll my own slightly-customized boot-from-flash live cd? thanks, bill

• Attach radeon driver to specific PCI devices?

  - by genpfault

  I have two Radeon cards in this machine, a 6570 and a 6950: lspci | grep VGA: 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Turks [Radeon HD 6570] 02:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Cayman PRO [Radeon HD 6950] I'm trying to get VGA passthrough to work with KVM on Debian Wheezy, passing through the 6950 as a secondary video card to a Windows 7 guest.

• Is it possible to be a Linux professional studying on your own?

  - by Marc Jr

  I read economics at university(nothing to see with linux, isn't it? :P). I have some basic knowledge about booting process, Linux Kernel compiling from source and stuff like that. But of course I have still much to learn sometimes some errors appears and "voila" I am lost. I had: Ubuntu, Fedora, OpenSuse, Arch.. using Gentoo now. I'd like to know what you linux users, professionals, administrators... would think it is the best way to learn linux in a professional way. Is it worth studying it and passing the LPIC test enough to work in the linux world? or do I need going to IT uni? I've heard LFS is a good way of learning about linux, is that real? I've been thinking about getting to LFS learn about more deeply about the linux process and learning scripts. It is possible to do this way? if anyone has a tip or a good way of doing, maybe someone did it. Any tip is very welcome. Words from a person in love with linux. :D The best, Marc

• April 2010 Critical Patch Update Released

  - by eric.maurice

  Hi, this is Eric Maurice. Today Oracle released the April 2010 Critical Patch Update (CPUApr2010),the first one to include security fixes for Oracle Solaris. Today's Critical Patch Update (CPU) provides 47 new security fixes across the following product families: Oracle Database Server, Oracle Fusion Middleware, Oracle Collaboration Suite, Oracle E-Business Suite, Oracle PeopleSoft Enterprise, Oracle Life Sciences, Retail, and Communications Industry Suites, and Oracle Solaris. 28 of these 47 new vulnerabilities are remotely exploitable without authentication, but the criticality of the affected components and the severity of these vulnerabilities vary greatly. Customers should, as usual, refer to the Risk Matrices in the CPU Advisory to assess the relevance of these fixes for their environment (and the urgency with which to apply the fixes). 7 of the 47 new vulnerabilities affect various versions of Oracle Database Server. None of these 7 vulnerabilities are remotely exploitable without authentication. Furthermore, none of these fixes are applicable to client-only deployments. The most severe CVSS Base Score for the Database Server vulnerabilities is 7.1. As a reminder, information about Oracle's use of the CVSS 2.0 standard can be found in Note 394487.1 (My Oracle Support subscription required). Note that this Critical Patch Update includes fixes for vulnerabilities that were publicly disclosed by David Litchfield at the BlackHat DC Conference in early February (CVE-2010-0866 and CVE-2010-0867). 5 of the 47 new vulnerabilities affect various components of the Oracle Fusion Middleware product family. The highest CVSS Base Score for these vulnerabilities is 7.5. Note that the patches for Oracle WebLogic Server are cumulative and this Critical Patch Update therefore also includes a fix for a vulnerability (CVE-2010-0073) that was the subject of a Security Alert issued by Oracle on February 4, 2010. Customers, who have not applied the previously-released patch, should apply today's Critical Patch Update as soon as possible. As stated at the beginning of this blog, it is also noteworthy to highlight that this Critical Patch Update provides 16 new fixes for the Sun product line. With the recent close of the Sun acquisition both security organizations have worked diligently to align Sun's previous security practices with Oracle's. Java users know that Oracle released a Critical Patch Update for Java SE and Java For Business earlier this month (in accordance with the Java patching schedule previously published by Sun Microsystems). Please note that for the first time, the Java advisories included CVSS Scores to help assess the severity of the new vulnerabilities fixed with the advisory. The rapid inclusion of the Solaris product lines in the Critical Patch Update and the extension of Oracle Software Security Assurance to Sun technologies are evidence of the flexibility of Oracle's security assurance programs. These should also result in tangible security benefits for the users of the Oracle hardware and software stack (such as a predictable patching schedule for all Oracle products).

• process and memory issue on linux server

  - by zapping

  Need some assistance in analyzing apache and php process running on linux server. Its a 8-core intel processor with 4GB ram. When the website on it runs the top displays like this. PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 23459 username1 16 0 151m 27m 8388 S 11.3 0.7 0:11.71 php5 23730 username1 16 0 151m 28m 8388 S 11.3 0.7 0:03.87 php5 23458 username1 16 0 151m 28m 8388 S 3.0 0.7 0:19.20 php5 16202 mysql 15 0 459m 38m 4624 S 0.7 1.0 62:33.81 mysqld 24141 nobody 15 0 311m 5832 2304 S 0.3 0.1 0:00.03 httpd Why does the command say php5 when the website is accessed. Both apache and php was preconfigured so not sure whats done there. Tried setting up the same site and db on a different server but on it the process shows httpd always and not php5. The site uses mysql db. The problem is server load seems to go till about 5.x when the website was access by about 16users. When the free -m command was given the output shows total used free shared buffers cached Mem: 3941 3727 213 0 236 2734 -/+ buffers/cache: 756 3184 Swap: 4095 0 4095 Lots of memory seems to be in cache and free memory is less. Even when the website is not accessed that is leaving it very much idle for about 2days the free memory showed just 190. When the site is accessed the free memory seems to be go till 90mb then it increases to about 150mb. It always seems to remain just about 200mb. Is it somehow related to the server load showing 5.x. Will adding some more RAM resolve the load issue?
