  • Stress test speed on a gateway?

    - by TheLQ
    I'm interested in stress testing my gateway server but am lost on how. Most of the stress testing applications I've seen only see how much load an app like Apache can handle, but not this. Essentially I want to send as many packets I can into this box with one computer on one card and see how many come out the other in another computer just to get an idea of what kind of load this can handle. I'm also interested how Snort will perform. I'm not really sure how to do this though. What tools could you recommend that could do this?

  • Can my laptop run dual 1080p (Sony Vaio - Nvidia 330M)

    - by Charlino
    I am looking to buy a monitor to setup dual monitors for my laptop and was wondering if my laptop could handle 2 x 1080p. I have a Sony Vaio VPCF116FG which has a Nvidia GeForce 330M chip and 1GB dedicated graphics memory. The laptop also has a Intel® Core™ i7-720QM Processor (1.60 GHz with Turbo Boost up to 2.80 GHz) but I don't know if that's relevant(?). The laptop screen has a native resolution of 1080p (1920 x 1080) so I'll be looking at buying a external monitor with 1080p to connect up using a HDMI cable. So, the question is, will my laptop be able to handle it's own 1080p screen AND an external 1080p screen? TIA, Charles

  • UDP flooding multiple servers

    - by Chris Gurney
    What do you suggest? Being UDP flooded as I write to multiple servers in different data centers in 5 different countries . Up to 250,000 packets a second. I believe Cisco routers 5505 would not handle that - (some of our datacenter hosters can offer them. Some have no firewalls to offer.) Our clients naturally have constant disconnects to the server they are on. Hacker started this about three weeks ago. Sometimes for a few hours - up to a few days. If we can't stop it hitting the server with firewalls then how do we stop the hacker - now there is the challenge! Update : Found some of the data centers offer up to 10 firewall rules but would their routers be able to handle the possible volume I am talking about? Thanks Chris

  • how to add parameters to startup delayer

    - by user23950
    Startup delayer is an application that is used to delay the execution of applications at startup. And I want to take advantage of this function so that the regular applications that I am opening would be automated. How can I use the parameters function so that I could choose what operating system I want to boot when virtual box is included in the startup delayer. What website I would want to be automatically opened with google chrome. What specific project will be opened in visual studio. And others. And please enlighten me if this is not the exact function the parameters has to perform. Please do tell me of other application that can do the things mentioned above.

  • nginx: server_name and server_addr wrong with reverse proxy in front of it

    - by user41356
    I have stunnel in front of nginx in order to handle ssl. (I'm aware that nginx can handle ssl, but I'm migrating off nginx and this is a necessary step.) Stunnel and nginx are running on the same box. Without stunnel in front of nginx, nginx got the server_addr and server_name as the public ip of the box and the domain of the url I was fetching, respectively. Now with stunnel, nginx thinks the server_addr and server_name are 127.0.0.1 and localhost respectively. This is screwing up a bunch of things. How can I make nginx get (or stunnel send) the correct server_addr and server_name?

  • Apache mod_jk replacing mod_rewrite rules

    - by organicveggie
    We have a slightly complex Apache 2.2 setup in front of a Tomcat 6.0 instance. The main Tomcat webapp is deployed in: /opt/tomcat/webapps/ROOT But we also have static content that we update semi-regularly. We didn't want to force a new build and deploy of the webapp, so that's stored separately in folders like: /opt/tomcat/webapps/css /opt/tomcat/webapps/foo /opt/tomcat/webapps/bar To handle this from Apache, we use mod_rewrite and rules look something like the following: RewriteCond %{REQUEST_FILENAME} -f RewriteRule ^/css/(.*)$ - [L] RewriteCond ROOT/%{REQUEST_FILENAME} -f RewriteRule ^/css/(.*)$ ROOT/$1 [L] RewriteCond %{REQUEST_FILENAME} -f RewriteRule ^(.*)\.(jpg|png|html|js)$ - [L] RewriteCond ROOT/%{REQUEST_FILENAME} -f RewriteRule ^(.*)\.(jpg|png|html|js)$ - [L] RewriteRule ^/(.*)$ http://localhost:8080/$1 [P,L] ProxyPassReverse / http://localhost:8080/ I now think I might want to start using mod_jk and I have two questions: Is it even worth using mod_jk? I don't need load balancing. Is it even possible to handle the cases I outlined where the static content is referenced as "http://www.example.com/css/foo.css", but we don't know if it's located in the Tomcat webapp or in one of the static folders.

  • Nginx location issue

    - by dave
    I'm trying to set a longer (30 day) 'expires' header for my (images only) in the /misc-stuff/ directory. This is what I'm using for my site : # Serve static files directly from nginx location ~* \.(jpg|jpeg|gif|png|bmp|ico|pdf|flv|swf|exe|html|htm|txt|css|js) { add_header Cache-Control public; add_header Cache-Control must-revalidate; expires 7d; } I want to be able to keep that code in to handle regular site images, but create a new block to handle the /misc-stuff/ directory. I have tried : location ^~ /misc-stuff/ { ... } The problem I'm having now is that my backup .php files in that directory show up as plain text if someone tries to access it. How do I set it up so ONLY .gif images in the /misc-stuff/ directory are effected?

  • Handling Junk Email with Apple Mail.app and Gmail

    - by Axeva
    I've just setup my Apple Mail client to work with Google Apps through IMAP. One lingering question is how to best handle SPAM (Junk Mail), however. In their Help section, Google recommends that we disable junk filtering on the client. http://mail.google.com/support/bin/answer.py?answer=78892 This leads me to wonder what we should do when a junk message makes it past Google's filter? Do I just delete the message? If I do, the Google spam filter will never improve and "learn" that the message was junk. Do I have to log in to the web interface at Google to mark the message as spam? That seems a bit arduous for every spam email I get. What's the best way to handle this? Thanks!

  • Does servers to >$1000 really have a memory limit of 4GB?

    - by Sandra
    Hi, I am looking for a server, and when I look at the specs some of the servers can only handle 4GB. Other can handle 8GB or 16GB, and others 64GB. Can that really be true? Is this really a hardware limitation, or are they disabling it in the BIOS, so there is no way to use 16GB on a 4GB supported server? An example is the Dell PowerEdge SC 440. Only 4GB supported, they say. Would Linux allow me to use 16GB on a 4GB server? Sandra

  • Win 7 slow Log off on Domain

    - by e2e2
    Our Windows 7 computers/laptops are very slow at logoff, around 7 minutes (no problem at log on). We don't have this issue on XP clients. Problem occurs after adding the Win7 clients on domain. I tried to reset user profile. After resetting logoff takes around 2 minuted and after everyday it takes longer and longer We are using roaming profiles. Event Viewer: Event ID: 6005 The winlogon notification subscriber is taking long time to handle the notification event (Logoff). And then a minute later Event ID: 6006 - The winlogon notification subscriber took 300 second(s) to handle the notification event (Logoff).

  • Can I use two of the same type of PCI Sound Cards in one computer?

    - by Eamon
    I recently purchased two Rocketfish 5.1 PCI Sound Cards from Best Buy. These are going to be used for audio production and radio broadcasting, so one card can handle live audio, the other can handle cue audio. After installing both cards, I get strange noises from the broadcasting program, and then the computer locks up solid. I have to hard restart to get it back up. This only happens when the two audio cards are installed on the computer. I have tried switching them around to different PCI slots, with the same result.

  • Disabling a touchpad in Windows

    - by Shamaoke
    I want to permanently disable a touchpad in Windows running on my laptop, since firstly, I use a mouse, and secondly, when I work, I often touch it accidentally what causes definite inconviniences. I tried the following approaches to disable it but with no result: Turned it off through BIOS — there's no such function there; Turned it off through the touchpad configuration utility — there's no such function there; Turned it off through the device manager — the disable button is inactive; Turned it off through a hotkey (Fn + F1 in my case) — the hotkey doesn't work; Uninstalled the proprietary driver — Windows automatically downloaded the standard driver; Uninstalled the standard driver and turned off the automatic driver download function (Win + R ? "systempropertiesadvanced" ? Hardware ? Device Installation Settings) — all the same, Windows downloaded and installed the driver. How can I disable a touchpad? Windows 7; the Alps touchpad.

  • Ngnix as reverse proxy for Apache name-based vhosts

    - by Ben Carleton
    I am running several websites on Apache currently utilizing name-based vhosts. All of the sites are on the same server. I would like to add Ngnix on a new server to sit in front of Apache as a caching reverse proxy. What is the best way to handle the multiple name-based vhosts? Should I simply have Nginx handle the names and run each Apache vhost on a separate port? Or is there a way to just have Nginx pass the hostname to Apache and have apache take care of the domain names?

  • Implementing dry-run in bash scripts

    - by Apikot
    How would one implement a dry-run option in a bash script? I can think of either wrapping every single command in an if and echoing out the command instead of running it if the script is running with dry-run. Another way would be to define a function and then passing each command call through that function. Something like: function _run () { if [[ "$DRY_RUN" ]]; then echo $@ else $@ fi } _run mv /tmp/file /tmp/file2 DRY_RUN=true _run mv /tmp/file /tmp/file2 Is this just wrong and there is a much better way of doing it?

  • Help make sense of a KillDisk error/log

    - by user284194
    I have a hard drive that I've been trying to reformat. I tried reformatting it in the windows XP and 7 installers, and in an Ubuntu live cd with gparted. I tried using dd to 'zero' the drive as well with no success. Finally I ran across KillDisk after a search. I tried to zero the disk again with KillDisk and after 8 hours of zeroing I get the following errors in the log: ----------------------------------------Erase Session Begin--------------------------------------- 2010-03-23 19:35:54 Active@ KILLDISK for Windows Build 5.1.39 started Target: WDC WD2500KS-00MJB0 232.9 GB Located on: WDC WD2500KS-00MJB0 (Serial number: WD-WCANK9604799) Erase method: One Pass Zeros (1 pass) Passes: 1 Bad (unwritable) sectors detected from 1701 to 488397167 on Hard Disk 1.

  • nginx regex locations w/ different roots not working as expected

    - by Wells Oliver
    I have the following two rules: location / { root /var/www/default; } location ~* /myapp(.*)$ { root /home/me/myapp/www; try_files $uri $uri/ /handle.php?url=$uri&$args; } When I browse to myapp/foo it works- kind of, the error is logged as a 404: *3 open() "/var/www/default/handle.php" failed (2: No such file or directory) - so its handling the regex match but just not using the right document root-- why is this? For the record, I am trying to get /myapp/* requests handled by the second location, and everything else the first.

  • umount bind of stale NFS

    - by Paul Eisner
    i've got a problem removing mounts created with mount -o bind from a locally mounted NFS folder. Assume the following mount structure: NFS mounted directory: $ mount -o rw,soft,tcp,intr,timeo=10,retrans=2,retry=1 \ 10.20.0.1:/srv/source /srv/nfs-source Bound directory: $ mount -o bind /srv/nfs-source/sub1 /srv/bind-target/sub1 Which results in this mount map $ mount /dev/sda1 on / type ext3 (rw,errors=remount-ro) # ... 10.20.0.1:/srv/source on /srv/nfs-source type nfs (rw,soft,tcp,intr,timeo=10,retrans=2,retry=1,addr=10.20.0.100) /srv/nfs-source/sub1 on /srv/bind-target/sub1 type none (rw,bind) If the server (10.20.0.1) goes down (eg ifdown eth0), the handles become stale, which is expected. I can now un-mount the NFS mount with force $ umount -f /srv/nfs-source This takes some seconds, but works without any problems. However, i cannot un-mount the bound directory in /srv/bind-target/sub1. The forced umount results in: $ umount -f /srv/bind-target/sub1 umount2: Stale NFS file handle umount: /srv/bind-target/sub1: Stale NFS file handle umount2: Stale NFS file handle Here is a trace http://pastebin.com/ipvvrVmB I've tried umounting the sub-directories beforehand, find any processes accessing anything within the NFS or bind mounts (there are none). lsof also complains: $ lsof -n lsof: WARNING: can't stat() nfs file system /srv/nfs-source Output information may be incomplete. lsof: WARNING: can't stat() nfs file system /srv/bind-target/sub1 (deleted) Output information may be incomplete. lsof: WARNING: can't stat() nfs file system /srv/bind-target/ Output information may be incomplete. I've tried with recent stable Linux kernels 3.2.17, 3.2.19 and 3.3.8 (cannot use 3.4.x, cause need the grsecurity patch, which is not, yet, supported - grsecurity is not patched in in the tests above!). My nfs-utils are version 1.2.2 (debian stable). Does anybody have an idea how i can either: force the un-mount some other way? (any dirty trick is welcome, data loss or damage neglible at this point) use something else instead of mount -o bind? (cannot use soft links, cause mounted directories will be used in chroot; bindfs via FUSE is far to slow to be an option) Thanks, Paul Update 1 With 2.6.32.59 the umount of the (stale) sub-mounts work just fine. It seems to be a kernel regression bug. The above tests where with NFSv3. Additional tests with NFSv4 showed no change. Update 2 We have tested now multiple 2.6 and 3.x kernels and are now sure, that this was introduced in 3.0.x. We will fille a bug report, hopefully they figure it out.

  • Modify MDT wizard to automate computer naming

    - by Jeramy
    I originally posted this question to StackOverflow, but upon further consideration it might be more appropriate here. Situation: I am imaging new systems using MDT Lite-Touch. I am trying to customize the wizard to automate the naming of new systems so that they include a prefix "AG-", a department code which is selected from a drop-down box in the wizard page (eg. "COMM"), and finally the serial number of the computer being imaged, so that my result in this case would be "AG-COMM-1234567890" Status: I have banged away at this for a while but my Google searches have not turned up answers, my trial-and-error is not producing useful error messages and I think I am missing some fundamentals of how to get variables from the wizard page into the variables used by the lite-touch wizard. Progress: I first created the HTML page which I will include below and added a script to the page to concatenate the pieces into a variable called OSDComputername which, for testing, I could output in a msgbox and get to display correctly. The problem with this is I don't know how to trigger the script then assign it to the OSDComputername variable that is used throughout the rest of the Light-Touch process. I changed the script to a function and added it to DeployWiz_Initization.vbs then used the Initialization field in WDS to call it. I'll include the function below. The problem with this is I would get "Undefined Variable" for OSDComputername and I am not sure it is pulling the data from the HTML correctly. I tried adding the scripting into the customsettings.ini file after the "OSDComputername=" This resulted in the wizard just outputting my code in text as the computer name. I am now trying adding variables to "Properties=" (eg.DepartmentName) in the customsettings.ini, pulling thier value from the HTML Form and setting that value to the variable in my function in DeployWiz_Initization.vbs and calling them after "OSDComputername=" in the fashion "OSDComputername="AG-" & %DepartmentName%" in customsettings.ini I am rebuilding right now and will see how this goes Any help would be appreciated.

  • 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?

    Hi there, I have a ps1 script in which I define 2 functions as such: function Invoke-Sql([string]$query) { Invoke-Sqlcmd -ServerInstance $Server -Database $DB -User $User -Password $Password -Query $query } function Get-Queued { Invoke-Sql "Select * From Comment where AwaitsModeration = 1" } I then call the ps1 file by typing it in (it's in a folder in the path, and autocompletion works) However, I cannot start using the functions. I am confused, because when I copy / paste the functions into the console, all is fine and they work. I also have a function defined in my profile, and it works. Where am I thinking wrong, why doesn't it work what I'm trying to do?

  • AWS SSL Load Balancer

    - by Jay Francis
    OK, I am looking for some pointers. Basically I have a white-label app/site that will allow users to setup their own domain to use for their customer front-end. We have 2 dedicated servers and a load balancer. The problem is SSL, we were thinking about using AWS ELB to handle the SSL loadbalancing, but cant seem to figure out if it will properly handle it, it seems to be setup to work with EC2 instances, but we are using externally hosted servers via a loadbalancer. A blog post by AWS looks similar to what we need but it only seems to work with EC2 instances. http://aws.typepad.com/aws/2011/08/elastic-load-balancer-ssl-support-options.html Anyone had experience setting ELS SSL load balancers up to work with external servers?
