  • redirect from mysite.com to www.mysite.com

    - by jml
    hi there, i know that this has been answered many many times, so if someone wants to point me to another thread that answers my question specifically, that is fine... for right now, my searches aren't yielding many results. so i have a website like mysite.com that has a flash swf embedded in it and i go to www.mysite.com ... all of the sudden, things don't work properly. i would like to get to the bottom of this, because it's not like the page just "doesn't load" at all; it loads and i can only do certain things; as if certain functionality is disabled (might be url requests for specific urls etc). do i need to manage this in my control panel? i wouldn't assume so, because the site loads; just has a crippled functionality from within the swf. i was thinking it might have more to do with my crossdomain.xml file; could this be the case? thanks for any tips or suggestions.

  • Reinserted a RAID disk. Defined as foreign. Is import or clear the correct choice?

    - by Petrus
    I have re-inserted a RAID disk, on a DELL server with Windows Server 2008. The drive-status indicator was changing between a green and amber light, and the monitor gave the following message: There are offline or missing virtual drives with preserved cache. Please check the cables and ensure that all drives are present. Press any key to enter the configuration utility. I pressed a key and the PERC 6/I Integrated BIOS Configuration Utility showed that the RAID Status for that disk was Offline. After reinsertion of the disk the monitor is giving the following message: Foreign configuration(s) found on adapter. Press any key to continue or ‘C’ load the configuration utility, or press ‘F’ to import foreign configuration(s) and continue. After checking around on the net I am uncertain if I should choose import or clear. I cannot find out if an import means importing information from the array/system to the now foreign disk or the other way, i.e. importing information from the foreign disk to the array/system that was actually working fine. Also; if clear is a necessary thing to do ahead of a rebuild of that disk, or if clear means to clear the system to somehow make it ready to import the information from the foreign disk to the array/system, which is not what I want. I imagine that making the wrong choice here might be fatal. Please help clearing this out by telling what to choose and why.

  • saslauthd using too much memory

    Woke up today to see my site slow/unresponsive. Pulled up top and it looks like a ton of saslauthd processes have spun up using about 64m of RAM each, causing the machine to enter swap space.

The machine has been sending a lot of email through postfix, so this could be related. Anyone know why so many may have spun up? Are they safe to kill? Thanks!

  • How to configure fastcgi to work with ligttpd in ubuntu

  • Cannot print certain colours on Ubuntu with HP Laser Printer

    - by ILMV
    We have a load of machines running Ubuntu in our office, they are either on 8.04 or 9.10. We have a server which connects a HP JetDirect that connects to a HP 3550 Colour Laser printer using CUPS. The problem we are having is we cannot print red, magenta or yellow at 100%, I've got a picture of the Ubuntu test page to demonstrate my problem: This is obviously a pretty big problem as we are constantly receiving documents with these colours and cannot successfully print them off, we cannot just switch the grayscale, our business depends on being able to print colour (seems trivial but we handle lots of artwork). We're using the recommended driver HP Color LaserJet 3550 footmatic/pxljr (recommended), there is another driver in the list labelled HP Color LaserJet 3550 footmatic/hpijs. These are production printers so need to make sure any setting change won't kick is in the nuts. It would appear HPIJS is for HP Inkjets, makes sense I guess. The problem doesn't occur in Windows. RESOLVED I've managed to solve the problem, I did indeed use the HPIJS driver (apparently for inkjets) but it seems to have worked, we're going to roll with it for now to see how we get on with it.

  • Is dual-booting an OS more or less secure than running a virtual machine?

    - by Mark
    I run two operating systems on two separate disk partitions on the same physical machine (a modern MacBook Pro). In order to isolate them from each other, I've taken the following steps: Configured /etc/fstab with ro,noauto (read-only, no auto-mount) Fully encrypted each partition with a separate encryption key (committed to memory) Let's assume that a virus infects my first partition unbeknownst to me. I log out of the first partition (which encrypts the volume), and then turn off the machine to clear the RAM. I then un-encrypt and boot into the second partition. Can I be reasonably confident that the virus has not / cannot infect both partitions, or am I playing with fire here? I realize that MBPs don't ship with a TPM, so a boot-loader infection going unnoticed is still a theoretical possibility. However, this risk seems about equal to the risk of the VMWare/VirtualBox Hypervisor being exploited when running a guest OS, especially since the MBP line uses UEFI instead of BIOS. This leads to my question: is the dual-partitioning approach outlined above more or less secure than using a Virtual Machine for isolation of services? Would that change if my computer had a TPM installed? Background: Note that I am of course taking all the usual additional precautions, such as checking for OS software updates daily, not logging in as an Admin user unless absolutely necessary, running real-time antivirus programs on both partitions, running a host-based firewall, monitoring outgoing network connections, etc. My question is really a public check to see if I'm overlooking anything here and try to figure out if my dual-boot scheme actually is more secure than the Virtual Machine route. Most importantly, I'm just looking to learn more about security issues. EDIT #1: As pointed out in the comments, the scenario is a bit on the paranoid side for my particular use-case. But think about people who may be in corporate or government settings and are considering using a Virtual Machine to run services or applications that are considered "high risk". Are they better off using a VM or a dual-boot scenario as I outlined? An answer that effectively weighs any pros/cons to that trade-off is what I'm really looking for in an answer to this post. EDIT #2: This question was partially fueled by debate about whether a Virtual Machine actually protects a host OS at all. Personally, I think it does, but consider this quote from Theo de Raadt on the OpenBSD mailing list: x86 virtualization is about basically placing another nearly full kernel, full of new bugs, on top of a nasty x86 architecture which barely has correct page protection. Then running your operating system on the other side of this brand new pile of shit. You are absolutely deluded, if not stupid, if you think that a worldwide collection of software engineers who can't write operating systems or applications without security holes, can then turn around and suddenly write virtualization layers without security holes. -http://kerneltrap.org/OpenBSD/Virtualization_Security By quoting Theo's argument, I'm not endorsing it. I'm simply pointing out that there are multiple perspectives here, so I'm trying to find out more about the issue.

  • IIS 6 ASP.NET default handler-mappings and virtual directories

    - by mlauter
    I'm having a problem with setting a default mapping in IIS 6. I want to secure *.HTML files with ASP.NET forms authentication. The problem seems to have something to do with using virtual directories to hold the html files. Here's how it's setup: sample directory tree c:/inetpub/ (nothing in here) d:/web_files/my_web_apps d:/web_files/my_web_apps/app1/ d:/web_files/my_web_apps/app2/ d:/web_files/my_web_apps/html_files/ app1 and app2 both access the same html_files directory, so html_files is set as a virtual directory in the web apps in IIS... sample web directory tree //app1/html_files/ (points to physical directory: d:/web_files/my_web_apps/html_files/) //app2/html_files/ (points to physical directory: d:/web_files/my_web_apps/html_files/) If I put a file called test.html in the root of //app1/ and then add the default mapping to the asp.net dll and setup my security on the root folder with deny="?", then accessing test.html works exactly as expected. If I'm not authenticated, it takes me to the login.aspx page, and if I am authenticated then it displays test.html. If I put the test.html file in the html_files directory I get a totally different behavior. Now the login.aspx page loads and I stuck some code in to check if I was still authenticated: <p>autheticated: <%=User.Identity.IsAuthenticated%></p> I figured it would say false because why else would it bother to load the login page? Nope, it says true - so it knows i'm authenticated, but it won't give me access to the test.html file. I've spent several hours on this and haven't been able to solve it. I'm going to spend some more time on google to see if I've missed something. Fingers crossed.

  • Issues with sustained traffic with PFSense

    - by Farseeker
    Last week we had to replace our PFSense firewall because it had a catastrophic hardware failure. All but one of the NICs were taken out of the old server and put into the new one. The one NIC that was not moved was the LAN NIC as this is on-board. The other NICs are all WAN connections and the must all be present (i.e. I can't disable one just for the sake of testing) After re-installing PFSense and restoring our backup of the configuration, everything came back online just fine, however on the new hardware any download that takes longer than about 10 seconds just times out in the middle. Example 1: Downloading from Microsoft.com goes at about 900k/sec and times out after about 10 seconds (thus, just under 10Mb of content) Example 2: Downloading from cnet.com goes at about 300k/sec and times out after about 10 seconds (thus, about 3Mb of content). By times out, I mean that the download just stops, and you have to pause/resume to get the next part done, repeat and rinse until the download is complete. However it's not consistant, sometimes it's 10 seconds, sometimes it's 4 seconds, and it sometimes you can't even load a heavy HTML page because the page never finishes. I assume this is most likely because PFSense does not like the onboard NIC, as this is the primary difference between the two servers. It's recognised as NFE0, and there's no room in the server for any more NICs and I don't have any dual-port NICs handy to experiment with a different LAN connection. I've never had to troubleshoot this sort of issue before. Can anyone give me some pointers about where to start? Linux is not my forte so please be kind!

    I'm experiencing some significant performance issues on an NFS server. I've been reading up a bit on partition alignment, and I think I have my partitions mis-aligned. I can't find anything that tells me how to actually quantify the effects of mis-aligned partitions. Some of the general information I found suggests the performance penalty can be quite high (upwards of 60%) and others say it's negligible. What I want to do is determine if partition alignment is a factor in this server's performance problems or not; and if so, to what degree? So I'll put my info out here, and hopefully the community can confirm if my partitions are indeed mis-aligned, and if so, help me put a number to what the performance cost is. Server is a Dell R510 with dual E5620 CPUs and 8 GB RAM. There are eight 15k 2.5” 600 GB drives (Seagate ST3600057SS) configured in hardware RAID-6 with a single hot spare. RAID controller is a Dell PERC H700 w/512MB cache (Linux sees this as a LSI MegaSAS 9260). OS is CentOS 5.6, home directory partition is ext3, with options “rw,data=journal,usrquota”. I have the HW RAID configured to present two virtual disks to the OS: /dev/sda for the OS (boot, root and swap partitions), and /dev/sdb for a big NFS share: [root@lnxutil1 ~]# parted -s /dev/sda unit s print Model: DELL PERC H700 (scsi) Disk /dev/sda: 134217599s Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 63s 465884s 465822s primary ext2 boot 2 465885s 134207009s 133741125s primary lvm [root@lnxutil1 ~]# parted -s /dev/sdb unit s print Model: DELL PERC H700 (scsi) Disk /dev/sdb: 5720768639s Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 34s 5720768606s 5720768573s lvm Edit 1 Using the cfq IO scheduler (default for CentOS 5.6): # cat /sys/block/sd{a,b}/queue/scheduler noop anticipatory deadline [cfq] noop anticipatory deadline [cfq] Chunk size is the same as strip size, right?

  • How do i tell if my drivers are up to date on Acer?

    - by joe
    Hoping some kind souls can help me out ? I got a blue screen the other day after trying to load sandboxie. So its obviously conflicting with something. I checked if my drivers were up to date on my acer aspire one AOD270 on this intel based site; http://www.drivermanager.com/en/down...tel&Logo=intel Its showing i have 2 drivers that need updating ; Intel NM10 Express chipset and the Realtek PCIE Cardreader. I have no idea whether to do the update via the Intel Driver update site or the Acer drivers download page? I then ran Bluescreenview and on the dump file its showing ; ''caused by driver'' igdkmd32.sys ''file description'' Intel (R) WDDM Kernel mode driver ''product name''Intel Graphics Accelerator Drivers for Windows 7(R) I bought the laptop here in SE Asia about a year ago. The ''HOT!! NEW download tool'' on the acer drivers site (below) doesnt seem to work and the info about removing and installing drivers is limited. Not sure what to trust on non acer/manufacturer sites. http://support.acer.com/us/en/produc...1&modelId=4040 I've located the igdkmd32.sys file inside the INTEL GRAPHICS MEDIA ACCELERATOR 3600 SERIES 8.14.8.1064. When i click on ''update driver'' in control panel it searches and says its up to date. In windows maintenance it says this intel had a problem, but no solution. For all i know my drivers could be up to date and its something else. Can anybody advise a dummy step by step the process i should follow ? I've never done this before. eg do i delete the old driver first and then download the new one.how much of a problem i could cause by downloading this type of thing wrongly? As yet i havent downloaded any drivers. I've asked on other forums but no luck as yet. Thanks for any help!

  • What benchmark tool to use to benchmark hardware for VM server?

    - by Mark0978
    We are setting up a new piece of hardware to virtualize several of our servers on. Choices are RAID 5, RAID 6, and RAID 0+1. We are wanting to benchmark all three before we go live with the machine, but I'm not sure how to test the speed. Since we will be using it to host VMs, what will the actual disk traffic look like? What can I use to see if RAID 6 is too slow? Short of setting up the system with all the VM's on it and running that way, then redoing on all the work, I'm not sure how to test it. It them becomes more of a subjective test than an objective one. I'm worried that RAID6 will have too much overhead, that RAID5 will be to fragile with 3TB drives and I've never worked with 0+1 at all. So in short I'd like to setup the base machine (which will be running Linux) and then test the underlying SW RAID for speed. What kind of tool exists to simulate this kind of load? Barring the lack of a specific tool, how about a generic FS testing tool that will simulate different loads?

  • Restoring snapshot for Microsoft Exchange server

    - by Mugen
    Hi, The background: I need to do some testing with Microsoft exchange server. Specifically, I'll be installing some software on the Microsoft exchange server machine and uninstalling that same software again. The problem I face: While I repeatedly do this with different versions of my software there is a chance that sometime later the Exchange server installation might get corrupted. When that happens I would need to reinstall Exchange server which I feel is somewhat of a chore. So what I am planning to do is to install the Ms Exchange server on a virtual machine in VMware ESX server and take a snapshot so that during my work whenever the installation is corrupted I can restore the snapshot. So here's my question: Would restoring the snapshot for the Microsoft Exchange server virtual machine work correctly? I'm not familiar with the intricacies of exchange server and any changes (if any) that happen with the Domain controller when we use or install an exchange server (Personally I don't think that should happen but just making sure). I have a shortage of time and hence decided to post this question here. Could someone please tell me whether restoring a snapshot for Exchange server would work fine? Thanks a load, Mugen

  • "Run As Administrator" on program right click failing and not launching program

    - by GONeale
    This problem lies within a relatively fresh x64 Windows 7 install ~4 weeks, but is also a problem I have seen on Windows Vista machines (x86 versions). Since the other day, any programs attempted to be launched via right clicking on a shortcut (.lnk)'s context menu and pressing - "Run As Administrator" for instance, in the Quick Launch/Jump List in Windows 7 has failed, screen has not dimmed, no UAC popup. In fact the program does not even load. There is no way around this unless I use the shortcut version from "All Programs" which appears to work, very strange? I have performed no major software installs, nothing out of the ordinary. Has anybody encountered this or know what would be causing it? Here's an example of somebody else experiencing this problem in Vista with no solution: http://www.vistax64.com/vista-general/131918-strange-run-administrator-problem.html and I believe this problem is related, I also cannot right click - "Manage" on my computer): http://windows7forums.com/windows-7-support/5501-run-administrator-broken.html I am running the latest version of Avira AntiVir Virus Scanner and pretty concious of what I download, I don't think it is a virus, nor do I believe it is due to the RC Version of Windows 7, because I have seen the problem across multiple Operating Systems versions. Thanks guys.

  • Managing Apache to Compensate for WebDAV's Security Masking

    - by Tohuw
    When a user creates a file via WebDAV, the default behavior is that the file is owned by the user and group running the Apache process, with a umask of 022. Unfortunately, this makes it impossible for unprivileged users to write to the files by other means without being a member of the group Apache runs under (which strikes me as a particularly bad idea). My current solution is to set umask 000 in Apache's envvars and remove all world permissions from the webdav parent directory for the user. So, if the WebDAV share is /home/foo/www, then /home/foo/www is owned by www-data:foo with permissions of 770. This keeps other unprivileged users out, more or less, but it's hokey at best and a security disaster awaiting at worst. From my research and poking around at mod_dav and Apache, I cannot find a reasonable solution short of a cron job flipping all the permissions back (I'd rather not have the load and increased complexity on the server). SuExec won't work, either, because WebDAV operations are not going to execute as a different user. Any thoughts on this? Thank you.

  • Problem with wireless networking

    - by Rodnower
    Hello, I have atheros wifi hardware, intell chipset, gigabyte laptop and CentOS 5 installed. Now I try to use wireless network and get problems. First of all I want to say that I have 2 OS on my laptop, and when I load Windows XP I still may to access to the wireless network.

  • Exchange eMails In A Mailbox Appear To Be Blocked By A Dud Message

    - by John Judd
    I have a client with an Exchange server on which there are quite a few mailboxes. One mailbox in particular is causing some problems. When an email from a certain address arrives, it appears to prevent Exchange from successfully delivering the email to the Outlook Express inbox. The address in question is from an account with Bigpond, or at least I think it is, I didn't check to see if it was spoofed (only just occurred to me.) Any emails in the queue before the suspect email are delivered, then Express times out. When send/recv is retried those emails are re-received and the process times out again. The process I have for fixing this is to log in to the sever, load Outlook, open the recipients inbox, and delete the suspect email. Then retrying the send/recv on Express successfully retrieves all the messages (except for the deleted message.) This solves the immediate problem, but this has happened several times now, and each time requires the process above to correct it. What I am wondering is if there is anything I can do to fix this permanently. It seems to me that Exchange should reject a dud email message rather than getting stuck. Does anyone know what could be causing this, and how I can fix it?

  • UPS with a HP Proliant server

    - by Groo
    We placed a EATON Ellipse Max 1500 (900W) as the UPS for our HP Proliant ML350 G6. Upon first power failure (actually we only moved the UPS' input plug to a different socket), server immediatelly turned off, and the Health LED turned red and started blinking. UPS was in operation for about a week before that, with battery fully charged to 100%. Since our server's hot-plug supply is 460W, we are pretty sure we haven't overloaded it, the server was completely idle at that time (no web or win apps running except Windows Server core services). Then we tried to do the same with a different, no-name older PC (Core 2 Duo, 2Gb RAM) with a generic power supply (not sure what the power is) and it continued working when we pulled the plug out. UPS load was less than 15% (measured in the provided Eaton utility). We measured the UPS' output voltage using a smart oscilloscope and the THD of the UPS output waveform turned out to be 40%. Did you have similar experiences? Could this be a faulty UPS? Or a faulty power supply? Or some HP sensors configured to trigger too strictly? I wouldn't like replacing this UPS with the same brand, to get same results. [Edit] I also tried to do this while the server is turned off. While the UPS is working on battery, server will not start - as soon as I press the power button, Health LED starts blinking red.

  • Linux Mint 14 severe overheating

    - by agvares
    I've tried switching to Mint (it was Mint 12) about 6 months ago, but failed to do it due to enormous overheating which made it virtually impossible to run any applications more complex than Gedit. Time had passed, and now I'm back again with Mint 14, but feeling way more determined. What I face are the following issues: 1) Great overheating (and by great I mean that just by doing nothing my CPU temp is floating around 70-75 C, which I find a lot) 2) Running multiple applications (let's say Chrome, Skype and Pidgin) results in critical overheating and immediate shutdown of the system 3) Due to the stuff listed above, my battery drains in about 10-15 minutes, pretty much turning my laptop into a crippled desktop machine I've got a HP-dv6 laptop (i7, 6gb RAM, dual graphics) Here's the output of lspci: 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200/2nd Generation Core Processor Family PCI Express Root Port (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:1a.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5) 00:1c.1 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 2 (rev b5) 00:1c.2 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 3 (rev b5) 00:1c.3 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 4 (rev b5) 00:1d.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation HM65 Express Chipset Family LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05) 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Whistler XT [AMD Radeon HD 6700M Series] 07:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

  • NetBackup prefers "Scratch" tapes over dedicated tapes

    - by wfaulk
    I have a NetBackup 6.0MP7 installation running on Windows Server 2003. It functions as the only Master Server and Media Server. I swap a full set of tapes in and out every week, but leave a set of tapes with their Volume Pool set to "Scratch" in all the time. The weekly tape sets then get rotated back in after a period of time. Largely, this works fine. I seldom actually need the scratch tapes, but every once in a while, a backup will run over what I have dedicated to the task. However, one week's set of tapes consistently gets declined in favor of the scratch pool. The backup policies are the same for every week, they all have "Policy Volume Pool" set to "NetBackup", and all of the tapes for every week (beside the scratch tapes) have had their pools assigned as "NetBackup", definitely including the week that always gets ignored. That said, it doesn't ignore all of the NetBackup pool tapes for that week. It does usually write to two or three of them, but it writes to like 20 of the scratch tapes. (I haven't thought to look to see if it's always the same two or three tapes.) And this problem never seems to occur for any other week. It doesn't load the tapes and then reject them; it never seems to try to use them at all. They are not flagged as frozen. They are all active and unassigned when I swap them in. The tapes are in a Quantum PX510 tape library. The NetBackup server is attached to the library/robot via fibrechannel going through an HP-branded Brocade switch. I'm not an expert on NetBackup at all. I don't really even know where to look. Any advice on logs to look at or logging to enable or really anything at all would be appreciated. I'll keep an eye on the question and update it if anyone needs any more info to help.

  • Toshiba laptop cd drive read causes OS to totally freeze

    - by Fujishiro
    Okay I'll try to write an understandable summary. Forgive me if I'll fail with that attempt though. So. There is a Toshiba Satellite notebook. Got Windows 7 x86 Professional (OEM) installed on it, everything is fine (okay.. somewhat). The problem. If you put an audio or any kind of disc into the drive, something starts to eat the PC. Back then when the owner told me about this, he put an audio disc into the lappy. Winamp caused the IO load, 100%. Tried taskkill, taskkill /T, tried powershell, EVERYTHING. You just can NOT kill winamp or anything which becomes the blocker at that time. Even if you kill almost everything, laptop won't do a clear shutdown. Also I tried to use the force switch at 'shutdown' from cmd, but no use. (So: At these times you can use the laptop, but the blocker/explorer/disc becomes gray as a non-responding app. You can try to kill them, but that won't work, nor you can shutdown the machine). (Also tried using PID, but no use. For the highest IO I used the "select columns" from Task Manager and enabled the IO columns.) My first hunch was the problematic disc, autoplay and it tries to read tries to read (still shouldn't kill the PC). Disabled autoplay, removed winamp. Tried other software, etc. Everything was ok. Few days later the owner tried to put a disc into the machine and it started to reproduce the same symptoms but with a totally different disc. Uhm what to know. Virus is not an option, protected by BitDefender (valid license) and Spybot. Thanks if you have ANY idea about this strange problem. ps.: For now, the owner uses Daemon tools + Blindwrite as an alternative for those apps which wouldnt start without the disc.

    I got nginx + uWSGI running on localhost inside a virtualenv with a simple hello world program, but I get this error when I replace the hello world with a simple Flask app: File "./wsgi_configuration_module.py", line 1, in <module> from flask import Flask ImportError: No module named flask unable to load app mountpoint Here's the flask app (wsgi_configuration_module.py): from flask import Flask application = Flask(__name__) @application.route("/") def hello(): return "hello world" if __name__ == "__main__": application.run() uWSGI config (app_conf.xml): <uwsgi> <socket>127.0.0.1:9001</socket> <chdir>/srv/www/labs/application</chdir> <pythonpath>/srv/www</pythonpath> <module>wsgi_configuration_module</module> <callable>application</callable> <no-site>true</no-site> </uwsgi> nginx config: server { listen 80; server_name localhost; access_log /srv/www/labs/logs/access.log; error_log /srv/www/labs/logs/error.log; location / { include uwsgi_params; uwsgi_pass 127.0.0.1:9001; } location /static { root /srv/www/labs/public_html/static/; index index.html index.htm; } } virtualenv stored in ~/virtual_env with Python 2.7 + nginx + uWSGI + Flask installed in a virtualenv called basic. Things I've tried to solve this: set the --home (-H) option to my virtualenv folder ~/virtual_env while running uWSGI. Other info: I have the same setup working outside of a virtualenv. Things go wrong only when I try to replicate the setup inside of a virtualenv. Where have I gone wrong?

  • Linux NIC Bonding Issue (CentOS 4 / RHEL 3)

    - by jinanwow
    I am having an issue with bonding NICs on CentOS 4. It appears the bonding driver does work, but it is stuck in round-robin mode and I am trying to get to active-backup. The current config is: ifcfg-bond0 DEVICE=bond0 IPADDR=192.168.204.18 NETMASK=255.255.255.0 ONBOOT=yes BOOTPROTO=none USERCTL=no TYPE=Bonding BONDING_OPTS="mode=1 miimon=100" ifcfg-eth1 DEVICE=eth1 BOOTPROTO=none ONBOOT=yes TYPE=Ethernet MASTER=bond0 SLAVE=yes ifcfg-eth3 DEVICE=eth3 ONBOOT=yes BOOTPROTO=none TYPE=Ethernet MASTER=bond0 SLAVE=yes cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v2.6.3-rh (June 8, 2005) Bonding Mode: load balancing (round-robin) MII Status: up MII Polling Interval (ms): 0 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: eth1 MII Status: up Link Failure Count: 0 Permanent HW addr: 00:17:a4:8f:94:b1 Slave Interface: eth3 MII Status: up Link Failure Count: 0 Permanent HW addr: 00:1b:21:56:b8:69 cat /etc/modprobe.conf alias eth0 tg3 alias eth1 tg3 alias eth3 e1000 alias eth2 e1000 alias bond0 bonding options bond0 mode=1 miimon=100 I have tried moving the bonding information out of the ifcfg-bond0 into the modprobe configuration file. It seems that it is stuck in RR and I am trying to get it into the Active-backup (mode 1) state. Any ideas what would be causing this issue?
