• Linux - real-world hardware RAID controller tuning (scsi and cciss)

  - by ewwhite

  Most of the Linux systems I manage feature hardware RAID controllers (mostly HP Smart Array). They're all running RHEL or CentOS. I'm looking for real-world tunables to help optimize performance for setups that incorporate hardware RAID controllers with SAS disks (Smart Array, Perc, LSI, etc.) and battery-backed or flash-backed cache. Assume RAID 1+0 and multiple spindles (4+ disks). I spend a considerable amount of time tuning Linux network settings for low-latency and financial trading applications. But many of those options are well-documented (changing send/receive buffers, modifying TCP window settings, etc.). What are engineers doing on the storage side? Historically, I've made changes to the I/O scheduling elevator, recently opting for the deadline and noop schedulers to improve performance within my applications. As RHEL versions have progressed, I've also noticed that the compiled-in defaults for SCSI and CCISS block devices have changed as well. This has had an impact on the recommended storage subsystem settings over time. However, it's been awhile since I've seen any clear recommendations. And I know that the OS defaults aren't optimal. For example, it seems that the default read-ahead buffer of 128kb is extremely small for a deployment on server-class hardware. The following articles explore the performance impact of changing read-ahead cache and nr_requests values on the block queues. http://zackreed.me/articles/54-hp-smart-array-p410-controller-tuning http://www.overclock.net/t/515068/tuning-a-hp-smart-array-p400-with-linux-why-tuning-really-matters http://yoshinorimatsunobu.blogspot.com/2009/04/linux-io-scheduler-queue-size-and.html For example, these are suggested changes for an HP Smart Array RAID controller: echo "noop" > /sys/block/cciss\!c0d0/queue/scheduler blockdev --setra 65536 /dev/cciss/c0d0 echo 512 > /sys/block/cciss\!c0d0/queue/nr_requests echo 2048 > /sys/block/cciss\!c0d0/queue/read_ahead_kb What else can be reliably tuned to improve storage performance? I'm specifically looking for sysctl and sysfs options in production scenarios.

• FastCGI Error when installing PHP on IIS7.5

  - by ytoledano

  I'm trying to install MediaWiki on a Win2008r2 server, but can't manage to install PHP. Here's what I did: Grabbed a Zip archive of PHP and unzipped it into C:\PHP. Created two subdirs: c:\PHP\sessiondata and c:\PHP\uploadtemp. Granted modify rights to the IUSR account for the subdirs. Copied php.ini-production as php.ini Edited php.ini and made the following changes: fastcgi.impersonate = 1 cgi.fix_pathinfo = 1 cgi.force_redirect = 0 open_basedir = "c:\inetpub\wwwroot;c:\PHP\uploadtemp;C:\PHP\sessiondata" extension = php_mysql.dll extension_dir = "./ext" upload_tmp_dir = C:\PHP\uploadtemp session.save_path = C:\php\sessiondata Install Web server role, selected CGI and HTTP Redirection options. In the Handler Mappings: Added Module Mapping. Entered the following values: Path = *.php, Module = FastCgiModule, Executable = c:\php\php-cgi.exe, Name = PHP via FastCGI. Created a test page into wwwroot directory: phpinfo.php and set the contents like this: < ?php phpinfo(); ? Browsed to http://localhost/phpinfo.php But then I get: HTTP Error 500.0 - Internal Server Error An unknown FastCGI error occured Detailed Error Information Module: FastCgiModule Notification: ExecuteRequestHandler Handler: PHP via FastCGI Error Code: 0x800736b1 Requested URL: http://localhost:80/phpinfo.php Physical Path: C:\inetpub\wwwroot\phpinfo.php Logon Method: Anonymous Logon User: Anonymous Does anyone know what I'm doing wrong here? Thanks.

• PHP crashing during oAuth scripts

  - by FunkyChicken

  I just installed Nginx 1.2.4 and PHP 5.4.0 (from svn) (php fpm). CentOs 5.8 64 The problem I have is that PHP crashes the moment I run any social oAuth scripts. I have tried to log into Facebook, Twitter and Google with various scripts that I know work on my other servers. When I load the scripts I get a 502 error from Nginx. And I find these errors in the log: in php-fpm log: WARNING: [pool www] child 23821 exited on signal 11 (SIGSEGV) after 1132.862984 seconds from start in nginx log: ERROR: recv() failed (104: Connection reset by peer) while reading response header from upstream From what I can see, it goes wrong when PHP tries to make a request to any of the oAuth servers. https://github.com/mahmudahsan/PHP-SDK-3.0---Graph-API-base-Facebook-Connect-Tutorial-Source for example is one of the scripts that works perfectly on my other machines, but causes PHP to crash. I found: http://stackoverflow.com/questions/3616191/nginx-php-fpm-502-bad-gateway which seems to be a similar problem, but I cannot find a way to solve it. +++ UPDATE +++ Now I have been doing some debugging in 1 of the scripts that is playing up. If you go to line 808 http://pastebin.com/gSnzRtXb it runs the curl_exec() command. When that is ran, it crashes. If i echo'test';exit; just above that line, it echo's correctly, if i do it below that line, php crashes. Which means it's that line 808 which causes the crash. So I made a very simple script to do some testing: http://pastebin.com/Rshnyhcm which also uses curl_exec, but that runs just fine. So I started to dig deeper into that query from the facebook script to see what values the $opts array contains from line 806. Output of that array is: http://pastebin.com/Cq9ffd3R What the problem is, I still have no clue :(

• ZFS with L2ARC (SSD) slower for random seeks than without L2ARC

  - by Florian Kruse

  I am currently testing ZFS (Opensolaris 2009.06) in an older fileserver to evaluate its use for our needs. Our current setup is as follows: Dual core (2,4 GHz) with 4 GB RAM 3x SATA controller with 11 HDDs (250 GB) and one SSD (OCZ Vertex 2 100 GB) We want to evaluate the use of a L2ARC, so the current ZPOOL is: $ zpool status pool: tank state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM afstank ONLINE 0 0 0 raidz1 ONLINE 0 0 0 c11t0d0 ONLINE 0 0 0 c11t1d0 ONLINE 0 0 0 c11t2d0 ONLINE 0 0 0 c11t3d0 ONLINE 0 0 0 raidz1 ONLINE 0 0 0 c13t0d0 ONLINE 0 0 0 c13t1d0 ONLINE 0 0 0 c13t2d0 ONLINE 0 0 0 c13t3d0 ONLINE 0 0 0 cache c14t3d0 ONLINE 0 0 0 where c14t3d0 is the SSD (of course). We run IO tests with bonnie++ 1.03d, size is set to 200 GB (-s 200g) so that the test sample will never be completely in ARC/L2ARC. The results without SSD are (average values over several runs which show no differences) write_chr write_blk rewrite read_chr read_blk random seeks 101.998 kB/s 214.258 kB/s 96.673 kB/s 77.702 kB/s 254.695 kB/s 900 /s With SSD it becomes interesting. My assumption was that the results should be in worst case at least the same. While write/read/rewrite rates are not different, the random seek rate differs significantly between individual bonnie++ runs (between 188 /s and 1333 /s so far), average is 548 +- 200 /s, so below the value w/o SSD. So, my questions are mainly: Why do the random seek rates differ so much? If the seeks are really random, they should not differ much (my assumption). So, even if the SSD is impairing the performance it should be the same in each bonnie++ run. Why is the random seek performance worse in most of the bonnie++ runs? I would assume that some part of the bonnie++ data is in the L2ARC and random seeks on this data performs better while random seeks on other data just performs similarly like before.

• Problems with bash script, mysql inserts and launchd

  - by Armands

  ========= I am developing a automated system, which consists of 3 parts: mysql, bash and launchd. Bash script takes folders of work related stuff, zips, archives and puts info about them into database that is located on a local MAMP server. Everything works as expected when I run the script from terminal. But when I use Launchd to automatically run this script, it functions without errors and it does not put the values into database. I've tried to make logs of returned messages, but the logs end up being empty as the command has run the way it was supposed to. Any help would be appreciated! .plist contents <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.adevo.ari.zip</string> <key>ProgramArguments</key> <array> <string>/Volumes/Archive-Plus/B-ARCHIVE-PLUS/ZZ_UTILITY_FOLDER/Compress.sh</string> </array> <key>Nice</key> <integer>1</integer> <key>StartInterval</key> <integer>120</integer> <key>RunAtLoad</key> <true/> </dict> </plist> I made this .plist file just by searching the web.

• Cannot set video resolution above 640x480 after installing Windows XP SP2

  - by waanders

  I've installed Windows XP SP2 on a computer (there was not SP at all). Now the display settings are set back to 640x480 and 4 bits colors. And I can't change it, it's the only option in Settings tab of the Display dialog of Windows. The screen look awful now, how can I solve this problem?

• All virtualhosts serving Apache default files

  - by tj111

  I'm trying to configure Apache as an in-network webserver, and am using the sites-available/sites-enabled feature as opposed to just static vhost files. I set up a couple VirtualHosts, all with a unique DocumentRoot, however request for all the VirtualHosts just serve up the "It's Working!" default file. I can't for the life of me figure out why it won't serve the content out of the correct directory. Here's the contents of the virtualhost directive files, let me know if I need to post more. default (note that apache renames this to 000-default in sites-enabled, so it's not an ordering issue) NameVirtualHost *:80 ServerName emp <VirtualHost *:80> ServerAdmin webmaster@localhost ServerName emp DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /var/log/apache2/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

• Website hosting from home - IIS6

  - by Paul

  I'm wanting to host a few websites from home, primarily because I'm using some BETA Microsoft software (.NET 4 and EF) and don't want to install it on my production server which is hosted at eukhost.com. Basically, I'm completely new to this sort of thing. So far, here is what I've done: Registered the domain name at namecheap.com (let's call it mydomain.com) Gone to "Nameserver Registration" in the panel and entered my IP address for the NS1 and NS2 records (let's say the IP is 0.0.0.0). Gone to "Domain Name Server Setup" and entered ns1.mydomain.com & ns2.mydomain.com Forwarded requests from port 80 to my internal IP (let's say 192.168.1.254) Created the website in IIS (I'm just testing with a single website so far, so have not created any host header values) Now, if I type in the IP address (http://0.0.0.0) I get the site as expected. However, if I enter http://www.mydomain.com I get an error saying "DNS Error - Cannot find server". I'm aware that there is a service from DynDNS that will automatically change the IP if I have a dynamic address, however my IP has remained static since I installed the ISP (since October) so I don't need this. Is there any way that I can get the DNS to work just by configuring IIS or something in Windows? I don't really want to have to pay for any 3rd party service. Thanks,

• How do I stop panning on a monitor that supports a specific resolution?

  - by IronicMuffin

  Hi all, I've been battling this for a few days now. Any and all help is appreciated. I have a planar monitor with a native res of 1280x1024. At one point, I had used PowerStrip to override "something" and set the res to 1600x1200, and it worked great. I then installed new intel graphics drivers for my 86895g (or w/e model) video card, which screwed up whatever settings I had. If I set it to 1600x1200 this time, it would set the res correctly, but give me a 1280x1024 viewport and the screen would pan when the mouse got to the edges of the screen. Absolutely not useful. Ok, so I was limited to 1280x1024 now. W/e. Now...enter new video card with two video ports. I have two monitors now and the latest nVidia drivers. I decide to try to get dual 1600x1200 going...ended up screwing the original monitor up so much now that it's at 1280x1024, with a 1024x768 viewport and panning! Absolutely not usable now. So what I need, and I can't seem to find on any forums, is help doing one or more of the following: Clearing out all monitor/edid info out of the windows registry without corrupting the registry. Actually correctly override the EDID values and get my sweet res back. Some other way of getting back to at least dual 1280x1024 with NO panning. Note: My device manager shows 4 monitors for some reason. My registry shows entries for all sorts of monitors that have been hooked up to the machine over the years. It's making it difficult to debug. Experience with PowerStrip would be helpful. I've been mucking with Phoenix EDID designer and MonInfo as well, but I'm stumbling around in the dark with these. Windows XP SP2 nVidia GeForce 6200 nVidia drivers: v258.96 Monitor: Planar PL 1910M Thanks!

• APC fragmentation on EC2 Micro for Wordpress + W3TC

  I'm trying to optimize APC for my Amazon EC2 Micro server running one Wordpress-site with W3TC. I've started with the settings advised by TechZilla in another topic but I keep getting high fragmentation with 50% of space being free.

• Can't get intel atom g-500 video driver to work with ubuntu 10.10 netbook edition.

  - by Matthew

  First of all I am completely new to Linux, so if you respond, please do so in a 'linux for dummies' tone so that my brain will be able to process it. I recently installed ubuntu on my dell mini-inspiron 1010. It has one GB of ram and an intel atom processor that uses the intel 500 graphic accelerator driver for windows and can run 1024x768 comfortably in xp. When I was installing ubuntu had quite a bit of trouble with my display and I am still unable to adjust my settings from 800x600x0x0 and there is no hardware acceleration. I visited the intel site and installed the linux drivers with the help of a friend but still no change. I tried adding resolution settings through xconf but they could not be applied even after I added the values. I am probably going about this totally wrong, but I've spent quite a lot of time browsing through forums and still haven't found a solution. Any help would be greatly appreciated. Also any other beginner tips that you have would be much appreciated. Thanks in advance, Matt

• iCloud stuff stops working while connected to OpenVPN

  - by Taco Bob

  I have a fairly simple OpenVPN setup on an OpenVZ VPS with Ubuntu 11.10. Client is the Viscosity client on Mac OS X 10.8.2, and after some testing, we can rule out the client as being part of the problem. Everything has been working fine except for Apple's iCloud stuff. Web surfing, email, FTP, NNTP, and Skype are all working as expected. It's ONLY the iCloud services that cease to function. If I connect to the VPN, iCloud stuff stops working. I no longer get anything in Messages, Calendar items don't get updated, and Notifications stop working. If I disconnect, the iCloud stuff all starts working. Connect again, iCloud stops working. Here's the server.conf: status openvpn-status.log log /var/log/openvpn.log verb 4 port 1194 proto udp dev tun ca /etc/openvpn/ca.crt cert /etc/openvpn/server.crt key /etc/openvpn/server.key dh /etc/openvpn/dh1024.pem server 10.9.8.0 255.255.255.0 ifconfig-pool-persist ipp.txt push "redirect-gateway def1" push “dhcp-option DNS 10.9.8.1? keepalive 10 120 duplicate-cn cipher BF-CBC comp-lzo user nobody group nogroup persist-key persist-tun tun-mtu 1500 mssfix 1400 I'm using iptables in a script, and it's also fairly simplistic. iptables -F iptables -t nat -F iptables -t mangle -F iptables -A FORWARD -i tun0 -o venet0 -j ACCEPT iptables -A FORWARD -i venet0 -o tun0 -j ACCEPT iptables -A INPUT -p tcp --dport 22 -j ACCEPT iptables -A INPUT -p tcp --dport 1194 -j ACCEPT iptables -A INPUT -p udp --dport 1194 -j ACCEPT iptables -t nat -A POSTROUTING -s 10.9.8.0/24 -j SNAT --to-source <server's public ip> echo 1 > /proc/sys/net/ipv4/ip_forward I tried forwarding ports as well, with no success. iptables -A FORWARD -p tcp -d 10.9.8.0/24 --dport 5222:5230 -j ACCEPT iptables -t nat -A PREROUTING -p tcp --dport 5222:5230 -j DNAT --to-destination 10.9.8.6 I am also sometimes behind a double-NAT situation that I have no control over. Client -> work VPN -> my OpenVPN box -> Internet. Client -> Airport Express -> ISP (which is doing NAT) -> my OpenVPN box -> Internet. Those two situations are just the fact of life where I am, and I cannot change them. I do have full control over my client and the OpenVPN server. I am completely out of ideas. I have posted a similar query at the OpenVPN forums, but it hasn't posted yet and seems to be in their moderation queue still. Tried on freenode irc channels, but nobody is awake, so here I am. I have Googled extensively for this, and can find nothing that is related. Help me get iCloud stuff working again! (I tried serverfault, it was closed as off-topic. I'm trying here and the Unix site as well. Here because it's a more general audience that might know more about OpenVPN based on the number of questions I see asked about it) EDIT: -I have also tried upgrading to Version: 2.3-beta1-debian0 - issue persists. -Removed all iptables rules except for the ones that flush -left this rule:iptables -t nat -A POSTROUTING -s 10.9.8.0/24 -j SNAT --to-source (server ip) -added iptables -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT still, nothing works.

• Error related to pkg-config when installing frei0r as part of another package

  - by Anentropic

  I am trying to build https://github.com/mltframework/shotcut on OS X Lion (using their script in scripts/build_shotcut.sh) and after numerous hurdles I'm stuck on this error: ./configure: line 16062: syntax error near unexpected token `OPENCV,' ./configure: line 16062: `PKG_CHECK_MODULES(OPENCV, opencv >= 1.0.0, HAVE_OPENCV=true, true)' ERROR: Unable to configure frei0r From what I already googled this means that the PKG_CHECK_MODULES macro hasn't been defined, which probably means there's something wrong with my pkg-config, which I installed via Homebrew. Sounds like the pkg.m4 file isn't found. When I brew install pkg-config I get the following warning: Warning: m4 macros were installed to "share/aclocal". Homebrew does not append "/usr/local/share/aclocal" to "/usr/share/aclocal/dirlist". If an autoconf script you use requires these m4 macros, you'll need to add this path manually. Well I've appended that line to the dirlist file and it doesn't fix the problem above. Can anyone suggest a way forward here? I have briefly tried building my own pkg-config from source but (bizarrely) when I tried to ./configure I got the following error: checking for pkg-config... no ./configure: line 13540: --exists: command not found configure: error: pkg-config and glib-2.0 not found, please set GLIB_CFLAGS and GLIB_LIBS to the correct values if building pkg-config needs pkg-config it seems like a weird catch 22 situation... I think this is probably an unnecessary sidetrack anyway.

• My client's solution of a Windows SBS 2011 VM on an Ubuntu host and VirtualBox is pinning the host CPU

  - by Scott Stamp

  Here's my situation, I've got a client hosting two servers (one VM), with the host providing VMware Zimbra, the other Windows Small Business Server 2011. Unfortunately, the person before me had configured this setup as follows. Host: Ubuntu Desktop Edition 10.04 (I know, again, not my choice) running VMware Zimbra 8GB of RAM On-board RAID1 of two 320GB Seagate Barracuda drives for the OS Software RAID5 of four 500GB WD Caviar Black drives on MDADM for bulk storage (sorry, I don't know the model #) A relatively competent quad-core Intel Core i7 CPU from the Nehalem architecture (not suspicious of this as the bottleneck) Guest: Windows Small Business Server 2011 4GB of RAM Host-equivalent CPU allocation VDI file for OS hosted on the on-board RAID, VDI file for storage hosted on the on-board RAID For some reason when running, the VM locks up when sitting nearly idle, and the VirtualBox process reports values of 240%+ in top (how is that even possible?!). Anyone have any ideas or suggestions? I'm totally stumped on this one. Happy to provide whatever logs you'd like to take a look at. Ideally I'd drop VirtualBox and provision this with VMware Workstation, but the client has objected to the (very nominal) costs involved. If hardware needs to be purchased to help, it will be, but we're considering upgrades a last-resort at this time. Thanks in advance! *fingers crossed*

• Apache Reverse proxy Http to https

  - by Coppes

  I have a website which is fully running on Https. For some reason i did get the task to find a way to convert a url for example: http://www.domain.com/a/e-nc/youless to a https version of it, without losing HTTP POST header such as the POST values which are in it. So i thought (not even sure) let's try to make a reversed proxy in apache and see how that works. Anyway after a lot of struggling i came to the point to ask it here. So to be speicific my goal is: Convert the http://www.domain.com/a/e-nc/youless to https://www.domain.com/a/e-nc/youless without losing the POST conditions. What i have tried until now is the following: Created a file called: proxiedhosts in my apache2/sites-enabled folder with the following contents: SSLProxyEngine On SSLProxyCACertificateFile /etc/apache2/ssl/certificate****.pem ProxyRequests Off ProxyPreserveHost On <Proxy *> Order allow,deny Allow from all </Proxy> ProxyPass /a/e-nc/youless/ https://www.domain.com/a/e-nc/youless/ ProxyPassReverse /a/e-nc/youless/ https://www.domain.com/a/e-nc/youless/ Thanks in advance!

• CentOS Latency High Troubleshooting

  - by Sarah Weinberger

  I have two CentOS servers connected via a 10 Gb fiber optic cable with a network emulator connected between them. All three units sit on a desk in the lab. There is also a regular 1 Gbit Ethernet cable connected to each of the machines, which provide internet connectivity. When I set the latency to something roughly below 30 ms, all is fine. When the latency gets to 70ms and above, and definitely 130ms, the network layer suspends. For instance, if I set the latency (delay) to 70ms, then launching TeamViewer (or any other application that uses network connectivity) never happens or does not work. There is no timeout message, simply no response. I have to lower to latency back down to zero to see any response and have the box start working. What is the problem and how would I go about fixing it? It seems to me some sort of setting in Linux causes one of the CentOS networking drivers to sit in an infinite loop or something. eth0 is the connection to the internet, all settings are default eth2 is the 10 Gbit fiber optic connection to the other computer with the MTU set to 9600 with all other parameters at default values.

• Can I convert an existing Firefox installation to ESR without a re-install?

  - by Iszi

  It took some jumping through hoops (including a mailing list subscription that I apparently didn't need) but I finally found where to download the Firefox ESR. This is great for fresh installs, but I was wondering if there's a way to simply convert existing installations to the ESR configuration without having to do a full install. As I understand it, the only difference between ESR and regular Firefox will be how they receive updates. After the new standard version of Firefox comes out, ESR releases will only receive critical security updates and bug fixes for the remainder of their support life. Newer versions of Firefox's standard build will have all the latest and greatest features, while ESR releases are meant to provide stability for environments that can't be expected to keep up with a new full version number change as often as Mozilla does them. In regular Firefox, the About screen shows that I am using the "release" update channel. Is switching to ESR really just a matter of switching the update channel? I presume this can be done in about:config by changing app.update.channel and probably also app.update.url. However, I don't know what these values should be for ESR or if anything else should be tweaked. So, is it possible to switch to ESR without a reinstall and, if so, how? (Note: While this question was written originally for Firefox 10, I expect any answers will apply to future ESR versions as well.)

• Ruby on Rails cannot find Initializer?

  - by Ryan M.

  Hello, I am trying to deploy an app to a fresh Ubuntu 10 installation using Passenger 2.2.15, Rails 2.3.5, Ruby 1.8.7, and Apache 2.2.14. However, even with a default rails app (sudo rails defaultapp), I am receiving the following error: "no such file to load -- initializer". I'm not sure which files you might need copies of in order to diagnose this problem, so I'll copy a few here and hope that it will help.

• Monitor is flashing through camera but not in the naked eye

  - by odyodyodys

  Two monitors: Samsung T23C350 - Samsung 2243NW Lets call the first A and the other B. A is a LED monitor with a 2ms response time (in specs) with a native resolution of 1920*1080@60Hz B is an older not-led one with 5ms response in specs with a resolution of 1680*1050@60Hz In the attached images and video you'll see that A (on the LEFT) is flickering but this is not visible to the naked eye. I took some pictures and videos with a camera and a mobile phone. This is also happening to all digital camcorders I've tested. A has a setting response time with values normal, fast, fastest. No matter the setting, the effect is the same. A on the left and B on the right. You can see the flickering, although both are @60Hz A video where you can see both monitors. A is always the left monitor. Another video where you can see what my digital camera sees. Another thing is that I managed to get a picture where the left monitor is completely black whilst the right one is displaying fine. This proves that the monitor is continuously flashing. My question is: Is this normal behavior and what is causing it? Am I affected by this fast flickering? I am using this as my primary monitor and as a programmer I have to keep my eyes on it for hours.

• Preventing DDOS/SYN attacks (as far as possible)

  - by Godius

  Recently my CENTOS machine has been under many attacks. I run MRTG and the TCP connections graph shoots up like crazy when an attack is going on. It results in the machine becoming inaccessible. My MRTG graph: mrtg graph This is my current /etc/sysctl.conf config # Kernel sysctl configuration file for Red Hat Linux # # For binary values, 0 is disabled, 1 is enabled.

Im no expert, but im not sure if this is ideal. My question is, what are some good things to add to the iptables file and possibly other files which would make it harder for the attackers to attack my machine without closing out any non-attacking users. Thanks in advance!

• Timeout option not working on efi windows 7/windows8 dual boot machine

  - by Guenter

  I hav a gigbyte GA-Z77m-D3h mobo and installed Windows 8 Pro and Windows 7 Ultimate on two SSDs (in that order) in EFI mode. Now when I start my computer, I get the windows boot menu (text mode) with the two OSses to choose, but I have to manually press RETURN to have the computer boot into the Win OS. Even if I wait an hour, no default action takes place. Using bcdedit (from either of the OSses) I can successfully change the time out value, and it shows up in the bcdedit (no params) output. But it doesn't fire ... Here is my current BCDEdit output (headers are in German, but values should be readable): Windows-Start-Manager --------------------- Bezeichner {bootmgr} device partition=O: path \EFI\Microsoft\Boot\bootmgfw.efi description Windows Boot Manager locale de-DE inherit {globalsettings} integrityservices Enable default {default} resumeobject {5ad2802c-c60a-11e2-acdb-80331c501b11} displayorder {default} {current} {5ad2802a-c60a-11e2-acdb-80331c501b11} {5ad28028-c60a-11e2-acdb-80331c501b11} {5ad28029-c60a-11e2-acdb-80331c501b11} toolsdisplayorder {memdiag} timeout 5 displaybootmenu Yes Windows-Startladeprogramm ------------------------- Bezeichner {default} device partition=W: path \Windows\system32\winload.efi description Windows 7 locale de-DE inherit {bootloadersettings} recoverysequence {5ad2802e-c60a-11e2-acdb-80331c501b11} recoveryenabled Yes osdevice partition=W: systemroot \Windows resumeobject {5ad2802c-c60a-11e2-acdb-80331c501b11} nx OptIn Windows-Startladeprogramm ------------------------- Bezeichner {current} device partition=C: path \Windows\system32\winload.efi description Windows 8 locale de-DE inherit {bootloadersettings} recoverysequence {5ad28033-c60a-11e2-acdb-80331c501b11} integrityservices Enable recoveryenabled Yes isolatedcontext Yes allowedinmemorysettings 0x15000075 osdevice partition=C: systemroot \Windows resumeobject {5ad28031-c60a-11e2-acdb-80331c501b11} nx OptIn bootmenupolicy Standard hypervisorlaunchtype Auto (this output is from Win8; the Win7 looks nearly identical) If maybe the problem comes from a bad EFI Windows boot manager installation, can this be fixed without loosing my windows installations?
