  • Gateway GT5220 Boot/POST Failure

    - by John Rudy
    I have a Gateway GT5220 I'm troubleshooting. It is, in fact, the machine I just gave my father for his birthday a couple months ago. (Prior to that, it was my home PC. My home PC is now the MacBook on which I'm writing this.) Before going any further, I suspect that the answer will be, "It's worse than that, it's dead, Jim, it's dead, Jim, it's dead, Jim." At least, mobo and/or CPU. The initial symptoms were as follows: Turn on power All fans fire up (thus making it so I can't hear if the hard drive is spinning or not, nor are my hands sensitive enough anymore to feel it) No LEDs remained lit on the front panel. (Initially, the hard drive indicator flashed briefly.) No beep, no video, no nothing. Following some advice I found here, I tried to "drain the stored power." After following those steps, the new symptoms were: Turn on power All fans fire up The front panel LEDs remained lit! After about 20, maybe 30 seconds, we had video! Sort of. We got to the Gateway splash/POST screen, which appeared thoroughly corrupted. How corrupted? Well, I imagine it's what a POST screen would look like after reading the wrong passage out of the Necronomicon: It stayed there. I gave it at least 5, maybe 6 minutes, and it didn't move. So I shut her down, started her up again, and now (this is where we currently stand, symptomatically) we have this: Turn on power All fans fire up The front panel LEDs remain lit No video, no beep, no nothing. I'm a software guy; haven't done real hardware troubleshooting in years. My gut tells me that the mobo and/or CPU is fried, and unfortunately my gut didn't get to be as big as it is being wrong all the time. :( In addition to the link above, I have read all of the following (trying to save you some LMGTFY trouble): Gateway Support POST Error Messages and Handling About a zillion (useless) POST beep code sites A kioskea.net post indicating that most likely we're at what I consider "total loss" (mobo and/or CPU) My questions: Are there any conditions other than mobo/CPU that could cause symptoms like these? Is it worth my time to try the next hardware troubleshooting step?(IE, remove all non-critical hardware from the machine, try to boot, systematically replace one by one until we find the failing component) Which mobos will fit in the Gateway GT5220 case (with rear ports correctly aligned)? (Why this is not a dupe: I wouldn't have posted this question if it hadn't been for the funkadelic possessed video display on the one occasion we got video out. I think that justified this not being an exact dupe. Of course, if the community overrules, I will understand.)

  • Deploying Django App with Nginx, Apache, mod_wsgi

    - by JCWong
    I have a django app which can run locally using the standard development environment. I want to now move this to EC2 for production. The django documentation suggests running with apache and mod_wsgi, and using nginx for loading static files. I am running Ubuntu 12.04 on an Ec2 box. My Django app, "ddt", contains a subdirectory "apache" with ddt.wsgi import os, sys apache_configuration= os.path.dirname(__file__) project = os.path.dirname(apache_configuration) workspace = os.path.dirname(project) sys.path.append(workspace) sys.path.append('/usr/lib/python2.7/site-packages/django/') sys.path.append('/home/jeffrey/www/ddt/') os.environ['DJANGO_SETTINGS_MODULE'] = 'ddt.settings' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler() I have mod_wsgi installed from apt. My apache/httpd.conf contains NameVirtualHost *:8080 WSGIScriptAlias / /home/jeffrey/www/ddt/apache/ddt.wsgi WSGIPythonPath /home/jeffrey/www/ddt <Directory /home/jeffrey/www/ddt/apache/> <Files ddt.wsgi> Order deny,allow Allow from all </Files> </Directory> Under apache2/sites-enabled <VirtualHost *:8080> ServerName www.mysite.com ServerAlias mysite.com <Directory /home/jeffrey/www/ddt/apache/> Order deny,allow Allow from all </Directory> LogLevel warn ErrorLog /home/jeffrey/www/ddt/logs/apache_error.log CustomLog /home/jeffrey/www/ddt/logs/apache_access.log combined WSGIDaemonProcess datadriventrading.com user=www-data group=www-data threads=25 WSGIProcessGroup datadriventrading.com WSGIScriptAlias / /home/jeffrey/www/ddt/apache/ddt.wsgi </VirtualHost> If I am correct, these 3 files above should correctly allow my django app to run on port 8080. I have the following nginx/proxy.conf file proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; Under nginx/sites-enabled server { listen 80; server_name www.mysite.com mysite.com; access_log /home/jeffrey/www/ddt/logs/nginx_access.log; error_log /home/jeffrey/www/ddt/logs/nginx_error.log; location / { proxy_pass http://127.0.0.1:8080; include /etc/nginx/proxy.conf; } location /media/ { root /home/jeffrey/www/ddt/; } } If I am correct these two files should setup nginx to take requests on the HTTP port 80, but then direct requests to apache which is running the django app on port 8080. If i go to mysite.com, all I see is Welcome to Nginx! Any advice for how to debug this?

  • The Koyal Group Info Mag News¦Charged building material could make the renewable grid a reality

    - by Chyler Tilton
    What if your cell phone didn’t come with a battery? Imagine, instead, if the material from which your phone was built was a battery. The promise of strong load-bearing materials that can also work as batteries represents something of a holy grail for engineers. And in a letter published online in Nano Letters last week, a team of researchers from Vanderbilt University describes what it says is a breakthrough in turning that dream into an electrocharged reality. The researchers etched nanopores into silicon layers, which were infused with a polyethylene oxide-ionic liquid composite and coated with an atomically thin layer of carbon. In doing so, they created small but strong supercapacitor battery systems, which stored electricity in a solid electrolyte, instead of using corrosive chemical liquids found in traditional batteries. These supercapacitors could store and release about 98 percent of the energy that was used to charge them, and they held onto their charges even as they were squashed and stretched at pressures up to 44 pounds per square inch. Small pieces of them were even strong enough to hang a laptop from—a big, fat Dell, no less. Although the supercapacitors resemble small charcoal wafers, they could theoretically be molded into just about any shape, including a cell phone’s casing or the chassis of a sedan. They could also be charged—and evacuated of their charge—in less time than is the case for traditional batteries. “We’ve demonstrated, for the first time, the simple proof-of-concept that this can be done,” says Cary Pint, an assistant professor in the university’s mechanical engineering department and one of the authors of the new paper. “Now we can extend this to all kinds of different materials systems to make practical composites with materials specifically tailored to a host of different types of applications. We see this as being just the tip of a very massive iceberg.” Pint says potential applications for such materials would go well beyond “neat tech gadgets,” eventually becoming a “transformational technology” in everything from rocket ships to sedans to home building materials. “These types of systems could range in size from electric powered aircraft all the way down to little tiny flying robots, where adding an extra on-board battery inhibits the potential capability of the system,” Pint says. And they could help the world shift to the intermittencies of renewable energy power grids, where powerful batteries are needed to help keep the lights on when the sun is down or when the wind is not blowing. “Using the materials that make up a home as the native platform for energy storage to complement intermittent resources could also open the door to improve the prospects for solar energy on the U.S. grid,” Pint says. “I personally believe that these types of multifunctional materials are critical to a sustainable electric grid system that integrates solar energy as a key power source.”

  • RHEL5: Can't create sparse file bigger than 256GB in tmpfs

    - by John Kugelman
    /var/log/lastlog gets written to when you log in. The size of this file is based off of the largest UID in the system. The larger the maximum UID, the larger this file is. Thankfully it's a sparse file so the size on disk is much smaller than the size ls reports (ls -s reports the size on disk). On our system we're authenticating against an Active Directory server, and the UIDs users are assigned end up being really, really large. Like, say, UID 900,000,000 for the first AD user, 900,000,001 for the second, etc. That's strange but should be okay. It results in /var/log/lastlog being huuuuuge, though--once an AD user logs in lastlog shows up as 280GB. Its real size is still small, thankfully. This works fine when /var/log/lastlog is stored on the hard drive on an ext3 filesystem. It breaks, however, if lastlog is stored in a tmpfs filesystem. Then it appears that the max file size for any file on the tmpfs is 256GB, so the sessreg program errors out trying to write to lastlog. Where is this 256GB limit coming from, and how can I increase it? As a simple test for creating large sparse files I've been doing: dd if=/dev/zero of=sparse-file bs=1 count=1 seek=300GB I've tried Googling for "tmpfs max file size", "256GB filesystem limit", "linux max file size", things like that. I haven't been able to find much. The only mention of 256GB I can find is that ext3 filesystems with 2KB blocks are limited to 256GB files. But our hard drives are formatted with 4K blocks so that doesn't seem to be it--not to mention this is happening in a tmpfs mounted ON TOP of the hard drive so the ext3 partition shouldn't be a factor. This is all happening on a 64-bit Red Hat Enterprise Linux 5.4 system. Interestingly, on my personal development machine, which is a 32-bit Fedora Core 6 box, I can create 300GB+ files in tmpfs filesystems no problem. On the RHEL5.4 systems it is no go.

  • samba 3.5 "force user" doesn't seem to be sticking

    - by myCubeIsMyCell
    After installing a new OS with newer version of samba, I'm having trouble accessing my shares. I can browse to the specific share, but only to the top level. As best I can tell from the logs, it seems the "force user" in the samba config isn't sticking beyond the initial connection. Details below. I installed a new version of CentOS on my storage server. My old CentOS (4?)install had samba version 3.0.33, new CentOS is using 3.5.10. No domain/AD involved ... just home workgroup. no real security... just some shares hidden & some defined as read-only. here's my config: [global] workgroup = WORKGROUP server string = Samba Server Version %v netbios name = luna security = share # logs split per machine log file = /var/log/samba/log.%m log level = 2 # max 50KB per log file, then rotate max log size = 50 winbind use default domain = Yes [strge] comment = please path = /storage browseable = yes read only = no force user = windowsguest force group = users guest ok = yes So... the problem I'm running into is that the 'force user' only seems to hold for the initial connection & I see all the top level folders fine. When I drill into a folder I get access denied - which appears to be due to my windows user info being sent (trys to authenticate xuser - a non-existant user to samba, so maps to nobody & fails). Here's the smb error msg: [2012/11/29 14:30:27.326195, 2] auth/auth.c:314(check_ntlm_password) check_ntlm_password: Authentication for user [xuser] -> [xuser] FAILED with error NT_STATUS_NO_SUCH_USER [2012/11/29 14:30:27.326251, 2] auth/auth.c:314(check_ntlm_password) check_ntlm_password: Authentication for user [nobody] -> [nobody] FAILED with error NT_STATUS_NO_SUCH_USER Most of the top level directories are 755, some 777. Either way, can not access them. If I do a chown -R windowsguest.users ... no change... but if I do a chmod -R to 777 or 755 they become browsable... but still can't create files (even for 777 ones). Not sure what role it plays if any... but had to recreate the user windowsguest under the new os install, uid & gid match old user. Seems the main issue as far as I can tell is that samba isn't maintaining the 'force user' - but I could be wildly off base. Client OS is win7 pro x64. Thanks for any suggestions or advice!

  • DVD Drive Failing on Windows 7

    - by Seth Spearman
    Hello, I have x64 Windows 7 running on an ASUS M50VM. The DVD drive works completely unreliably if not at all. But the story is not that simple so bear with me...here are the gory details. When I first got the machine it came with Windows XP and I upgraded it to Windows Vista X64 and the DVD worked fine. When Windows 7 RC2 came out I tried it on a Virtual Machine and I liked it so much that I upgraded the machine to Win7 RC1. The DVD worked fine. Of course, RC1 was going to start spontaneously rebooting, so when Windows 7 was released I DID A CLEAN INSTALL of Windows 7. Just to clarify...by clean install I mean I did a FORMAT of the HARD DRIVE and INSTALLED it from scratch. EVER since then the DVD mostly doesn't work. I can sometime read from disk but that will often hang. (Please see my description below of HANG for details.) CD or DVD writes ALWAYS fail with a HANG (I have done a successful write only one time.) Here is what I mean by HANG... *Explorer Window is unresponsive. *Any software accessing the DVD drive is unresponsive. *The DVD tray will not eject. *Using a paper clip will eject but the disk is usually spinning real hard. *Attempting to shut down windows will fail. I have waited as long as ten minutes but the whole OS seems to hang. I do a hard shutdown. *Sometimes accessing the DVD (when it does not cause a HANG) will still fail and the device will actually seem to disappear from the system until I reboot. A couple of other things. It is NOT a hardware failure. It is the Windows OS. I know this because I swapped out my DVD drive with a friend with the same model...his machine is fine (he is still running Vista X64) and my machine still fails. For what it is worth. I swapped out my primary disk with the INTEL 160GB SSD. EDIT Here is what System Information shows about my DVD drive Drive D: Description CD-ROM Drive Media Loaded No Media Type DVD Writer Name HL-DT-ST DVDRAM GSA-T50N ATA Device Manufacturer (Standard CD-ROM drives) Status OK Transfer Rate -1.00 kbytes/sec SCSI Target ID 0 PNP Device ID IDE\CDROMHL-DT-ST_DVDRAM_GSA-T50N________________RR04____\5&2B5B7F1D&0&1.0.0 Driver c:\windows\system32\drivers\cdrom.sys (6.1.7600.16385, 144.00 KB (147,456 bytes), 7/13/2009 7:19 PM) Any ideas?

  • OpenVPN not sending traffic to internet?

    I've set up openvpn on my pi and am running into a small issue. I can connect to the VPN server and ping it just fine, and I can also connect to other machines on my local network.

I don't think it's my client because both my laptop and my phone (which has an openvpn client) exhibit the same behavior. I had OpenVPN installed on this pi before using debian and it worked, so I don't think it's my router but of course anything is possible.

  • Why is the installation of certain programs always such a pain in Linux [closed]

    - by Saif Bechan
    I am new to Linux and I am trying to set up a server. For this I sometimes to need to install special software, but the installation of this is always such a pain. For example I wanted to try the htscanner to see if it did the job for me. When i got to the page there is NO INSTALLATION guide. I had to search for the right one on google. Even on google its a pain to find the right method. Just try it - google search.After a long search and tried different things I finally found out that I had te install some more software before it will work. The website says that the version I used did not had any dependencies. Thats a lie. Release0.8.1: No dependencies registered. You do need certain things for it to work. After managing to set it up it still didn't work I can't figure out why because there is no official guide on the website. So I wanted to just uninstall it and find a better solution. Uninstalling. Uninstalling something in Linux is a real mystery how this actually works. The best answer I got is to manually look for the files and delete them. Whats up with that! There is never something said about uninstalling on the websites. Even on the website of CentOS itself it tels you how to install something like rpmforge packages (it's a miracle they tell you and not have to google it) but there is no mention of what to do when you want to uninstall. Why not? The forums you get on when trying to solve your problem are most of the time in plain text, and you have to scroll trough huge error logs before you see somethings that vaguely resembles your question if you are lucky. The Question My question is if there are any recommended websites / forums that explain the basic concepts of installing and uninstalling software on Linux. And explain other useful operations. And not Wikipedia or the first hits of Google, I have been there already. I am looking for some easy to read trough guides on these operations on Linux. I have been on a lot of websites that explain some Linux operation, but I bet its easier to get a degree in rocket science than to read trough the website and understand what they try to say.

  • installing windows XP in Samsung SENS 145 plus notebook (no CD drive)

    - by user13267
    Hi I was trying to install Windows XP in a Samsung SENS 145 plus Notebook. It does not have a cd drive and I already managed to format it and semi install Windows XP, so now it does not even boot up either. This is what I did: Since it supports USB booting, I first made a bootable USB of Windows XP (Korean version; SP2 I think, may be SP 3) using Novicorp WinToFlash enter link description here. It managed to boot up at first and I was able to format the C driveand get Windows install to start up. It took forever to copy all the files from the USB and after the first reboot, before installation started, I cancelled the reboot from windows install, went to BIOS and changed the boot device priority from USB to internal hard drive. But now on bootup it showed me a list with two options for booting windows XP (much like in the case of a multi OS system) so I assumed that I had formatted drive D by mistake and installed XP there, instead of on C drive. Anyway, I chose one of them and it continued my Windows installation. I got the blue installation screen that shows ads about Windows XP on the right frame and estimated remaining time on the left. However, after completing the process, after the first reboot, instead of showing the Windows XP logo, it says \system32\hall.dll is missing (or corrupted I'm not sure, I needed to install the Korean version of windows and I could not exactly read the error message, however it was one that I have already seen in an English version installation, and I am sure it says either missing or corrupted). The problem is, now it shows the same error again when I try to reboot it from the USB drive as well. I tried to boot a portable version of Linux I made in another USB, but the computer does not boot up from that USB, and it shows hal.dll error when I try to boot it using the WIN XP installation USB I made, as well as when I try to boot it from the hard drive, where I suppose Win XP is now semiinstalled. So now I can't get the computer to start up at all, except going to the BIOS. What else can I try to solve this? Also, would it be possible to install XP on this computer by connecting it to another one running Windows 7 ultimate, through the ethernet card? That is, network just the two computers together, then install windows XP on the notebook from the desktop running windows 7? Please help, I'm running out of ideas on this one. If Korean version of windows XP is the problem then I am willing to install English version as well. (but I need to make sure if that is the real cause of the problem)

  • Trying to install wordpress inside rails app with nginx and fastcgi

    I have a rails app (let's call it myapp) running at www.myapp.com. I want to add a wordpress blog at www.myapp.com/blog. The webserver for the rails app is thin (see the upstream block).

  • Making application behind reverse proxy aware of https

    - by akaIDIOT
    https in tomcat being the hassel it is, I've been trying to get an Axis2 webapp to work behind a reverse proxy for ages now, can't seem to get it to work. The proxying itself works like a charm, but the app fails to generate 'links' (or ports as it concerns SOAP) using https. It would seem I need some way to let Axis2 know it is being accessed through https, even though the actual transport to it is done over http (proxied from localhost). The nginx config that proxies https to localhost:8080: server { listen 443; server_name localhost; ssl on; ssl_certificate /path/to/.pem ssl_certificate_key /path/to/.key; ssl_session_timeout 5m; ssl_protocols SSLv3 TLSv1; ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv3:+EXP; ssl_prefer_server_ciphers on; location / { # force some http-headers (avoid confusing tomcat) proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $http_host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; # pass requests to local tomcat server listening on default port 8080 proxy_pass http://localhost:8080; } } The proxy itself works fine, the info pages of the webapp work. The problem lies in the ports generated in the .wsdl: <wsdl:service name="WebService"> <wsdl:port name="WebServiceHttpSoap11Endpoint" binding="ns:WebServiceSoap11Binding"> <soap:address location="http://10.10.3.96/axis2/services/WebService.WebServiceHttpSoap11Endpoint/"/> </wsdl:port> <wsdl:port name="WebServiceHttpSoap12Endpoint" binding="ns:WebServiceSoap12Binding"> <soap12:address location="http://10.10.3.96/axis2/services/WebService.WebServiceHttpSoap12Endpoint/"/> </wsdl:port> <wsdl:port name="WebServiceHttpEndpoint" binding="ns:WebServiceHttpBinding"> <http:address location="http://10.10.3.96/axis2/services/WebService.WebServiceHttpEndpoint/"/> </wsdl:port> </wsdl:service> The Host header does its job; it shows 10.10.3.96 in stead of localhost, but as the snippet shows: it says http:// in front of it in stead of https://. My client app can't deal with this... Adding proxyPort and proxyName to the tomcat6 server.xml in the default <Connector> doesn't help; I'm at a loss on how to get this to work properly.

  • Areca 1280ml RAID6 volume set failed

    - by Richard
    Today we hit some kind of worst case scenario and are open to any kind of good ideas. Here is our problem: We are using several dedicated storage servers to host our virtual machines. Before I continue, here are the specs: Dedicated Server Machine Areca 1280ml RAID controller, Firmware 1.49 12x Samsung 1TB HDDs We configured one RAID6-set with 10 discs that contains one logical volume. We have two hot spares in the system. Today one HDD failed. This happens from time to time, so we replaced it. Upon rebuilding a second disc failed. Normally this is no fun. We stopped heavy IO-operations to ensure a stable RAID rebuild. Sadly the hot-spare disc failed while rebuilding and the whole thing stopped. Now we have the following situation: The controller says that the raid set is rebuilding The controller says that the volume failed It is a RAID 6 system and two discs failed, so the data has to be intact, but we cannot bring the volume online again to access the data. While searching we found the following leads. I don't know whether they are good or bad: Mirroring all the discs to a second set of drives. So we would have the possibility to try different things without loosing more than we already have. Trying to rebuild the array in R-Studio. But we have no real experience with the software. Pulling all drives, rebooting the system, changing into the areca controller bios, reinserting the HDDs one-by-one. Some people are saying that the brought the system online by this. Some are saying that the effect is zero. Some say, that they blew the whole thing. Using undocumented areca commands like "rescue" or "LeVel2ReScUe". Contacting a computer forensics service. But whoa... primary estimates by phone exceeded 20.000€. That's why we would kindly ask for help. Maybe we are missing the obvious? And yes of course, we have backups. But some systems lost one week of data, thats why we'd like to get the system up and running again. Any help, suggestions and questions are more than welcome.

  • Linux Fiber Channel Host Setup Basic

    - by Jim
    I've been googling for about 4 hours now with no luck. I am trying to setup a Linux server running Oracle Server 6.3 as a Fiber Channel host. And then connect it to a Dell Compellent Fibre Channel Host contain a 500GB Volume. The Oracle server itself contains two Brocade 815 FC HBAs. I've discovered their WWN(I think) via cat /sys/class/fc_host/host1/port_name 0x100000051efc3d85 cat /sys/class/fc_host/host2/port_name 0x100000051efc3d9f The next part is where I am at a loss. I've used iSCSI before...is FC the same deal where you have an initiator and a target? If so where do I specific that in linux? I'm also new to Fiber Channel as a protocol, so i am unsure what is needed to make a transaction? WWN and port ID? Similar to IP:Port combination in the Ethernet world. I've read alot regarding using systool, multipath, fc_transport commands, however none of these is recognized as a valid command from Oracle Server 6.3 Appreciate the guidance and assistance.

  • Solution to route/proxy SNMP Traps (or Netflow, generic UDP, etc) for network monitoring?

    - by Christopher Cashell
    I'm implementing a network monitoring solution for a very large network (approximately 5000 network devices). We'd like to have all devices on our network send SNMP traps to a single box (technically this will probably be an HA pair of boxes) and then have that box pass the SNMP traps on to the real processing boxes. This will allow us to have multiple back-end boxes handling traps, and to distribute load among those back end boxes. One key feature that we need is the ability to forward the traps to a specific box depending on the source address of the trap. Any suggestions for the best way to handle this? Among the things we've considered are: Using snmptrapd to accept the traps, and have it pass them off to a custom written perl handler script to rewrite the trap and send it to the proper processing box Using some sort of load balancing software running on a Linux box to handle this (having some difficulty finding many load balancing programs that will handle UDP) Using a Load Balancing Appliance (F5, etc) Using IPTables on a Linux box to route the SNMP traps with NATing We've currently implemented and are testing the last solution, with a Linux box with IPTables configured to receive the traps, and then depending on the source address of the trap, rewrite it with a destination nat (DNAT) so the packet gets sent to the proper server. For example: # Range: 10.0.0.0/19 Site: abc01 Destination: foo01 iptables -t nat -A PREROUTING -p udp --dport 162 -s 10.0.0.0/19 -j DNAT --to-destination 10.1.2.3 # Range: 10.0.33.0/21 Site: abc01 Destination: foo01 iptables -t nat -A PREROUTING -p udp --dport 162 -s 10.0.33.0/21 -j DNAT --to-destination 10.1.2.3 # Range: 10.1.0.0/16 Site: xyz01 Destination: bar01 iptables -t nat -A PREROUTING -p udp --dport 162 -s 10.1.0.0/16 -j DNAT --to-destination 10.3.2.1 This should work with excellent efficiency for basic trap routing, but it leaves us completely limited to what we can mach and filter on with IPTables, so we're concerned about flexibility for the future. Another feature that we'd really like, but isn't quite a "must have" is the ability to duplicate or mirror the UDP packets. Being able to take one incoming trap and route it to multiple destinations would be very useful. Has anyone tried any of the possible solutions above for SNMP traps (or Netflow, general UDP, etc) load balancing? Or can anyone think of any other alternatives to solve this?

  • Complete Active Directory redesign and GPO application

    - by Wolfgang Kuehne
    after much testing and hundreds of tries and hours invested I decided to consult you experts here. Overview: I want to apply some GPO to our users which will add some specific site to the Trusted Sites in Internet Explorer settings for all users. However, the more I try the more confusing the results become. The GPO is either applied to one group of users, or to another one. Finally, I came to the conclusion that this weird behavior is cause rather by the poor organization in Users and Groups in Active Directory. As such I want to kick the problem from the root: Redesign the Active Directory Users and Groups. Scenario: There is one Domain Controller, and we use Terminal Services (so there is a Terminal Server as well). Users usually log on to the Terminal Server using Remote Desktop to perform their daily tasks. I would classify the users in the following way: IT: Admins, Software Development Business: Administration, Management The current structure of the Active Directory Users and Groups is a result of the previous IT management. The company has used Small Business Server which has created multiple default user groups and containers. Unfortunately, the guys working before me have do no documentation at all. Now, as I inherit this structure I am in the no mans land. No idea which direction to head first. As you can see, the Active Directory User and Groups have become a bit confusing. There is no SBS anymore, but when migrating from SBS to the current Windows Server 2008 R2 environment the guys before me have simply copied the same structure. The real question: Where should I start cleaning from, ensuring that I won't break totally the current infrastructure? What is a nice organization for the scenario that I have explained above? Possible useful info for the current structure: Computers folder contains Terminal Services Computers user group Members: TerminalServer computer located at Server -> Terminalserver OU Member of: NONE Foreign Security Principals : EMPTY Managed Service Accounts : EMPTY Microsoft Exchange Security Groups : not sure if needed, our emails are administered by external service provider Distribution Groups : not sure if needed Security Groups : there are couple of groups which are needed SBS users : contains all the users Terminalserver : contains only the TerminalServer machine

  • Cisco IPSec, nat, and port forwarding don't play well together

    - by Alan
    I have two Cisco ADSL modems configured conventionally to nat the inside traffic to the ISP. That works. I have two port forwards on one of them for SMTP and IMAP from the outside to the inside this provides external access to the mail server. This works. The modem doing the port forwarding also terminates PPTP VPN traffic. There are two DNS servers one inside the office which resolves mail to the local address, one outside the office which resolves mail for the rest of the world to the external interface. That all works. I recently added an IPSec VPN between the two modems and that works for every thing EXCEPT connections over the IPSec VPN to the mail server on port 25 or 143 from workstations on the remote lan. It would seem that the modem with the port forwards is confusing traffic from the mail server destined for a machine on the other side of the IPSec VPN for traffic that should go back to a port forward connection. PPTP VPN traffic to the mail server is fine. Is this a scenario anybody is familiar with and are there any suggestions on how to work around it? Many thanks Alan But wait there is more..... This is the strategic parts of the nat config. A route map is used to exclude the lans that are reachable via IPSec tunnels from being Nated. int ethernet0 ip nat inside int dialer1 ip nat outside ip nat inside source route-map nonat interface Dialer1 overload route-map nonat permit 10 match ip address 105 access-list 105 remark *** Traffic to NAT access-list 105 deny ip 192.168.1.0 0.0.0.255 192.168.9.0 0.0.0.255 access-list 105 deny ip 192.168.1.0 0.0.0.255 192.168.48.0 0.0.0.255 access-list 105 permit ip 192.168.1.0 0.0.0.255 any ip nat inside source static tcp 192.168.1.241 25 interface Dialer1 25 ip nat inside source static tcp 192.168.1.241 143 interface Dialer1 143 At the risk of answering my own question, I resolved this outside the Cisco realm. I bound a secondary ip address to mail server 192.168.1.244, changed the port forwards to use it while leaving all the local and IPSec traffic to use 192.168.1.241 and the problem was solved. New port forwards. ip nat inside source static tcp 192.168.1.244 25 interface Dialer1 25 ip nat inside source static tcp 192.168.1.244 143 interface Dialer1 143 Obviously this is a messy solution and being able to fix this in the Cisco would be preferable.

  • My computer's dying :(

    - by j-t-s
    Hi All I have a sweet computer and have never had any real problems with it until now. I recently formatted my computer and all was well. But now my monitor randomly flickers. The monitor will just go black for about a second or two, then it'll return back to its normal state with all the stuff still on the screen. This is getting progressively worse. Another problem that has started is my computer randomly restarts. (I've managed to prevent it from restarting by removing the check in Automatically Restart from the Startup and Recovery Dialog. But I know this doesn't solve the problem). It also completely freezes up on me. One last thing, this morning I got a big blue screen. I can't remember what it said, but if it happens again I will take note of it and repost. Or if I can find some kind of a log file containing that bluescreen error I will post. I have checked all cords, and they're all fine. Nothing's loose. My computer isn't overheating either. I've taken the case off for 3 whole days and haven't used the computer for those 3 days, which has had no effect. I've checked the connections inside and nothing's loose there either. I know there's nothing wrong with my monitor because my friend has 2 computers and it works perfectly on those computers. I don't understand how my computer could suddenly become so unstable. I'm almost certain that I have no viruses; I full-scan my pc everyday for nastys, and have strict firewall settings. Anyway, I don't see how it could be a virus anyway simply due to the fact that I had these problems right after I formatted, and before I even had the chance to install or copy anything or even connect to the internet. I know it has nothing to do with the way I formatted the computer too, I've been fixing computers for years. Sorry for rambling on, just making sure I don't leave anything out. Has anybody else had this problem? Can somebody please try to help me with this? Thank you :)

  • TCP/IP & throughput between FreeNAS (BSD) server & other LAN machines

    - by Tim Dickerson
    I have got a question for someone that knows BSD a bit better than me that are in regards to my LAN setup at home/work here outside Chicago. I can't seem to fully optimize my network's (LAN) thoughput via my FreeNAS (BSD based) file server. It runs with the latest FreeBSD release which is modified to support several protocols for file transfers and more. Every machine that is behind my Smoothwall (Linux based) router is on the usual 192.168.0.x subnet and for most part works just fine. Behind the Smoothwall box, all machines are connected to a GB HP unmanaged switch. I host a large WISP here and have an OC-3 connection here at home/work and have no issues with downloading/uploading from/to the 'net'. My problem is with throughput. When I try and transfer large files...really any for that matter..between any of the machines to/and from the FreeNAS server via FTP, the max throughput I can achieve say between a Win 7 or a Linux box is ~65Mbit/sec. All machines are running Intel Pro 1000 GB NIC's and all cable is CAT6. Each is set to 'auto negotiation' and each shows 1500 MTU Full Duplex @1GB so I know the hardware is okay. I have not adjusted the MTU on any machine as I understand it to be pointless unless certain configurations are used (I assume I am not one of those). My settings for the FreeNAS machine are the following: # FreeNAS /etc/sysctl.conf - pertinent settings shown kern.ipc.maxsockbuf=262144 kern.ipc.nmbclusters=32768 kern.ipc.somaxconn=8192 kern.maxfiles=65536 kern.maxfilesperproc=32768 net.inet.tcp.delayed_ack=0 net.inet.tcp.inflight.enable=0 net.inet.tcp.path_mtu_discovery=0 net.inet.tcp.recvbuf_auto=1 net.inet.tcp.recvbuf_inc=524288 net.inet.tcp.recvbuf_max=16777216 net.inet.tcp.recvspace=65536 net.inet.tcp.rfc1323=1 net.inet.tcp.sendbuf_inc=16384 net.inet.tcp.sendbuf_max=16777216 net.inet.tcp.sendspace=65536 net.inet.udp.recvspace=65536 net.local.stream.recvspace=65536 net.local.stream.sendspace=65536 net.inet.tcp.hostcache.expire=1 From what I can tell, that looks to be a somewhat optimized profile for a typical BSD machine acting as a server for a LAN. I might be wrong and just wanted to find out from someone that knows BSD better than I do if indeed that is ok or if something is out of tune or what. Are there other ways I would find better for P2P file transfers? I honestly do not know what I SHOULD be looking for with respect to throughput between the NAS box and another client when xferring files via FTP, but I am told that what I get on average (40-70MB/sec) is too low for what it could be. I have thought about adding another NIC in the FreeNAS box as well as the Win7 machine and use a X-over cable via a static route, but wanted to check with someone first to see if that might be worth it or not. I don't know if doing that would bypass the HP GB switch and allow for a machine to machine xfer anyways. The FTP client I use is: Filezilla and have tried both active and passive modes with no real gain over each other. The NAS box runs ProFTPD.

  • How to bind old user's SID to new user to remain NTFS file ownership and permissions after freshly reinstall of Windows?

    - by LiuYan ??
    Each time we reinstalled Windows, it will create a new SID for user even the username is as same as before. // example (not real SID format, just show the problem) user SID -------------------- liuyan S-old-501 // old SID before reinstall liuyan S-new-501 // new SID after reinstall The annoying problem after reinstall is NTFS file owership and permissions on hard drive disk are still associated with old user's SID. I want to keep the ownership and permission setting of NTFS files, then want to let the new user take the old user's SID, so that I can access files as before without permission problem. The cacls command line tool can't be used in such situation, because the file does belongs to new user, so it will failed with Access is denied error. and it can't change ownership. Even if I can change the owership via SubInACL tool, cacls can't remove the old user's permission because the old user does not exist on new installation, and can't copy the old user's permission to new user. So, can we simply bind old user's SID to new user on the freshly installed Windows ? Sample test batch @echo off REM Additional tools used in this script REM PsGetSid http://technet.microsoft.com/en-us/sysinternals/bb897417 REM SubInACL http://www.microsoft.com/en-us/download/details.aspx?id=23510 REM REM make sure these tools are added into PATH set account=MyUserAccount set password=long-password set dir=test set file=test.txt echo Creating user [%account%] with password [%password%]... pause net user %account% %password% /add psgetsid %account% echo Done ! echo Making directory [%dir%] ... pause mkdir %dir% dir %dir%* /q echo Done ! echo Changing permissions of directory [%dir%]: only [%account%] and [%UserDomain%\%UserName%] has full access permission... pause cacls %dir% /G %account%:F cacls %dir% /E /G %UserDomain%\%UserName%:F dir %dir%* /q cacls %dir% echo Done ! echo Changing ownership of directory [%dir%] to [%account%]... pause subinacl /file %dir% /setowner=%account% dir %dir%* /q echo Done ! echo RunAs [%account%] user to write a file [%file%] in directory [%dir%]... pause runas /noprofile /env /user:%account% "cmd /k echo some text %DATE% %TIME% > %dir%\%file%" dir %dir% /q echo Done ! echo Deleting and Recreating user [%account%] (reinstall simulation) ... pause net user %account% /delete net user %account% %password% /add psgetsid %account% echo Done ! %account% is recreated, it has a new SID now echo Now, use this "same" account [%account%] to access [%dir%], it will failed with "Access is denied" pause runas /noprofile /env /user:%account% "cmd /k cacls %dir%" REM runas /noprofile /env /user:%account% "cmd /k type %dir%\%file%" echo Done ! echo Changing ownership of directory [%dir%] to NEW [%account%]... pause subinacl /file %dir% /setowner=%account% dir %dir%* /q cacls %dir% echo Done !

  • Passenger 2.2.4, nginx 0.7.61 and SSL

    - by boompa
    Has anyone had any luck configuring Passenger and nginx with SSL? I've spent hours trying to get this configuration working as I'd like, using what few resources there are out there on the net, and I can't get any of the supposedly forwarded headers to show up in the Rails controller. For example, with a conf file of the following (and multiple variations thereof): server { listen 3000; server_name .example.com; root /Users/website/public; passenger_enabled on; rails_env development; } server { listen 3443; root /Users/website/public; rails_env development; passenger_enabled on; ssl on; #ssl_verify_client on; ssl_certificate /Users/website/ssl/server.crt; ssl_certificate_key /Users/website/ssl/server.key; #ssl_client_certificate /Users/website/ssl/CA.crt; ssl_session_timeout 5m; ssl_protocols SSLv3 TLSv1; ssl_ciphers ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X_FORWARDED_PROTO https; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; #proxy_set_header X-SSL-Subject $ssl_client_s_dn; #proxy_set_header X-SSL-Issuer $ssl_client_i_dn; proxy_redirect off; proxy_max_temp_file_size 0; } and Rails code in the controller like this: request.headers.each { |k, v| RAILS_DEFAULT_LOGGER.error "Header #{k} Val #{v}" } other headers appear, but not those set in nginx, e.g.: Header rack.multithread Val false Header REQUEST_URI Val /login/new Header REMOTE_PORT Val 64021 Header rack.multiprocess Val true Header PASSENGER_USE_GLOBAL_QUEUE Val false Header PASSENGER_APP_TYPE Val rails Header SCGI Val 1 Header SERVER_PORT Val 3443 Header HTTP_ACCEPT_CHARSET Val ISO-8859-1,utf-8;q=0.7,*;q=0.7 Header rack.request.query_hash Val Header DOCUMENT_ROOT Val /Users/website/public I've even gone so far as to modify Passenger's abstract_request_handler's main_loop method, i.e., headers, input = parse_request(client) if headers if headers[REQUEST_METHOD] == PING process_ping(headers, input, client) else headers.each { |h,v| log.unknown "abstract_request_handler: #{h} = #{v}" } process_request(headers, input, client) end end only to find that the supposedly added headers do not exist there either: abstract_request_handler: HTTP_KEEP_ALIVE = 300 abstract_request_handler: HTTP_USER_AGENT = Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1) Gecko/20090624 Firefox/3.5 abstract_request_handler: PASSENGER_SPAWN_METHOD = smart-lv2 abstract_request_handler: CONTENT_LENGTH = 0 abstract_request_handler: HTTP_IF_NONE_MATCH = "b6e8b9afbc1110ee3bf0c87e119252ad" abstract_request_handler: HTTP_ACCEPT_LANGUAGE = en-us,en;q=0.5 abstract_request_handler: SERVER_PROTOCOL = HTTP/1.1 abstract_request_handler: HTTPS = on abstract_request_handler: REMOTE_ADDR = 127.0.0.1 abstract_request_handler: SERVER_SOFTWARE = nginx/0.7.61 abstract_request_handler: SERVER_ADDR = 127.0.0.1 abstract_request_handler: SCRIPT_NAME = abstract_request_handler: PASSENGER_ENVIRONMENT = development abstract_request_handler: REMOTE_PORT = 64021 abstract_request_handler: REQUEST_URI = /login/new abstract_request_handler: HTTP_ACCEPT_CHARSET = ISO-8859-1,utf-8;q=0.7,*;q=0.7 abstract_request_handler: SERVER_PORT = 3443 abstract_request_handler: SCGI = 1 abstract_request_handler: PASSENGER_APP_TYPE = rails abstract_request_handler: PASSENGER_USE_GLOBAL_QUEUE = false I'm tired of banging my head against the wall, so I'd truly appreciate any help I can get!

  • External USB HD issues with a twist (works on Windows7 but not XP)

    - by Eruditass
    I have this older external USB HD, 160 GB. I was using it to copy my Steam games to another computer. On the source computer, Windows 7 64-bit, everything worked fine. Drive reported no errors, had no hiccups, etc. Plugging it into the Windows XP 32-bit computer, it worked fine for looking through the files, moving files around on it (no real reading/writing, just modifying the filesystem table). However, when copying files from it to my internal HD, after a couple seconds to tens of minutes (seemingly random times), the USB device becomes unrecognized and it reports a delayed write error. Events in system log go like this, chronologically: (number times displayed)xSource (Event ID): "message" 2xdisk (51): An error was detected on device \Device\Harddisk1\D during a paging operation. 1xftdisk (57): The system failed to flush data to the transaction log. Corruption may occur. 1xApplication popup (26): Windows - Delayed Write Failed : Windows was unable to save all the data for the file E:\$Mft. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere. 1xntfs (50): {Delayed Write Failed} Windows was unable to save all the data for the file . The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere. These repeat for a while, then there is 10+ disk messages or ftdisk messages. Other notes: This occurs on random files at random times. This problem cannot be replicated on the Windows 7 source machine when copying from the HD to a different location on its local disk chkdsk /f was run and found no errors. chkdsk /f/r has the delayed write issue. drive was set to quick removal. Setting to performance in device manager yielded same result I am not writing anything to the USB external drive, so I am not sure why there is even a delayed write error (writing file access times?) local Windows XP was chkdsk'd without problems Windows XP machine has no problems with other USB HD's Various USB ports were attempted Rebooting did not help Occurs with SyncToy as well as windows explorer SMART status is good on both local drive and the external one Lack of gaming is making me cranky
