  • IIS: redirect to a webpage if authentication fails

    - by DrStalker
    We have an IIS site (MOSS 2007) that uses Windows Authentication. When a user that has forgotten their password tries to login the servers keeps sending 401 requests. This means on IE the user gets three prompts before IE displays a blank page, on Firefox the user is prompted over and over until they give up. We would like to change the behavior so if a user fails to login three times in a row we send them a redirect to a different site, instead of another 401 Forms authentication is not an option; the site has to remain on windows authentication to allow for SSO capabilities and certain sharepoint functions. Is there any way to tweak the IIS behavior to do this?

  • Fail rate of EBS snapshots and AMIs?

    - by user784637
    According to Amazon the fail rate of EBS volumes is: As an example, volumes that operate with 20 GB or less of modified data since their most recent Amazon EBS snapshot can expect an annual failure rate (AFR) of between 0.1% – 0.5%, where failure refers to a complete loss of the volume http://aws.amazon.com/ebs/ However, I was curious to know the fail rate of EBS snapshots and private AMIs that a system admin would take. Since the EBS snapshots and AMIs are stored in Amazon s3, is it safe to assume that the likelihood you cannot rollback to a previous snapshot or AMI the same likelihood that a file gets lost in s3? Amazon S3’s standard storage is: ... Designed to provide 99.999999999% durability and 99.99% availability of objects over a given year. http://aws.amazon.com/s3/

  • Unable to connect to EC2 instance after "reboot"

    - by KPL
    I am not able to connect to my m1.small instance after rebooting it. I have already associated the public IP with this instance. Upon checking the system log, this seems to be the issue: cloud-init-nonethttp://11.84: waiting 10 seconds for network device cloud-init-nonethttp://21.85: waiting 120 seconds for network device cloud-init-nonethttp://141.85: gave up waiting for a network device.

Attach a new network interface to the EC2 instance. The error still persists. eth1 shows up in the list but the "up" column is False.

  • AWS VPN Tunnel going down without traffic

    - by Asfura
    I managed to setup a site-to-site VPN connection from Amazon VPC to a company's network, and after a lot of configuration it was working fine, but now i realized that the VPN tunnel is DOWN every time there's no traffic going trough for a couple minutes. The only way that i have found to generate traffic is to reach the amazon instance from the company's network and then the tunnel goes up again. I had a cronjob doing ping every minute, but i think it should have a keepalive option somewhere, or at least a log file of the tunnels to find out what's going on. Any ideas to keep the tunnel up and/or bring it up from amazon? The firewall is a Checkpoint R75.20, it only allows one tunnel at a time for the same subnet, so i cant have both tunnels active. Thank you, any questions just ask. EDIT I forgot to add, the ping keepalive was working great (maybe generating a bit of traffic, but nothing to worry about), the connection dropped because i had to restart the instance, and it that little time it dropped me.

  • Why can I resolve this hostname but not a cname to this hostname?

    - by Joe Hopfgartner
    if a run dig against a hostname, i get the according cname, however i get an NXDOMAIN error (non existent domain). if i run dig against the cname i got, I can resolve it to an IP address successfully. It is reproduceable. On the system I am currently on it is always the case, on other systems it sometimes works and sometimes not, and on other systems it seems to work all the time. If i run using a nameserver i specify (for example googles public nameserver) i can successfully resolve the hostname. i would just blame the local system, but it seems i am not having the only one problems the 2nd domain (unrestrict.me) is hosted on amazon route 53 nameservers. the 1st one on another dns server which has proofen to be fully functional and reliable over the years. i once switchted with the other domain to amazon dns as well, everything seemed to work, also various dns health check tests reported fine, however i recieved a lot of support tickets that dns resolution would not work. is amazon just "bad" or am i doing something wrong? i did not tamper with the domain in any way on the local system (in case of caching or making a custom dns view or whatever...) joe@joe:~$ dig scorpion.premiumize.me ; <<>> DiG 9.8.1-P1 <<>> scorpion.premiumize.me ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 10222 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;scorpion.premiumize.me.

  • Symantec site slow only when using a Mac?

    - by cozmokramer8
    I didn't know this was possible but it certainly seems slow when only using a Mac. I participate in the Symantec Connect forums regularly and when I get on it with my Windows PC or laptop it loads perfectly, but my Mac laptop the site rarely loads or if it does it takes a couple minutes for each page. My question is why does a website run slower on the Mac vs PC? No other sites experience this same issue just the symantec connect forums. Thanks, Grant

  • How to automate an Amazon EC2 instance startup, execution of some commands and shutdown?

    - by Howiecamp
    I need to download 100 GB of files (it’s in about 150 files) within a 7 day period before they expire. The download is rate-limited by the host so it takes MUCH longer than the theoretical transfer rate based on normal Internet speeds. I have a script of curl http://curl.haxx.se/docs/manpage.html commands - one line per file. I had the idea of automatically spinning up n EC2 instances, executing the command and FTPing the files to a central location, then shutting down the machines. How would I do this? I don't care whether it's Linux or Windows.

  • Importing XML into an AWS RDS instance

    - by RoyHB
    I'm trying to load some xml into an AWS RDS (mySql) instance. The xml looks like: (it's an xml dump of the ISO-3661 codes) <?xml version="1.0" encoding="UTF-8"?> <countries> <countries name="Afghanistan" alpha-2="AF" alpha-3="AFG" country-code="004" iso_3166-2="ISO 3166-2:AF" region-code="142" sub-region-code="034"/> <countries name="Åland Islands" alpha-2="AX" alpha-3="ALA" country-code="248" iso_3166-2="ISO 3166-2:AX" region-code="150" sub-region-code="154"/> <countries name="Albania" alpha-2="AL" alpha-3="ALB" country-code="008" iso_3166-2="ISO 3166-2:AL" region-code="150" sub-region-code="039"/> <countries name="Algeria" alpha-2="DZ" alpha-3="DZA" country-code="012" iso_3166-2="ISO 3166-2:DZ" region-code="002" sub-region-code="015"/> The command that I'm running is: LOAD XML LOCAL INFILE '/var/www/ISO-3166_SMS_Country_Codes.xml' INTO TABLE `ISO-3661-codes`(`name`,`alpha-2`,`alpha-3`,`country-code`,`region-code`,`sub-region-code`); The error message I get is: ERROR 1148 (42000): The used command is not allowed with this MySQL version The infile that is referenced exists, I've selected a database before running the command and I have appropriate privileges on the database.

  • Static NAT in AWS's Virtual Private Cloud (VPC)

    - by user1050797
    Currently in a VPC with a public and a private subnet, all internet bound traffic from the private subnet could be routed via an NAT instance. The NAT instance will port address translate the packet's source IP to use the NAT instance's elastic IP, so the public server can reply to this public address. This is a PAT mechanism. My question is there a way for me to do a static NAT on my NAT instance -- Using the same NAT instance to static NAT an unassociated but reserved elastic IP to a private subnet host. This NAT instance will behave like a physical firewall doing static nat'ing for a bunch of private ip's.

  • Setting Up VirtualHosts for a local RubyOnRails Application

    - by chris Frisina
    I want to set up a VirtualHost so that when I type the project name in the address bar, it goes to the home page of the project. httpd-vhosts.conf files in both XAMPP configuration and apache configuration: <VirtualHost project> ServerAdmin [email protected] ServerName project DocumentRoot /Users/path/to/project/public <Directory "/Users/path/to/project/public"> Options Includes FollowSymLinks AllowOverride All Order deny,allow Allow from all </Directory> RewriteEngine On RewriteOptions inherit </VirtualHost> I have also tried with the path directly to the project folder, and not the public folder of the project. the httpd.conf of XAMPP and apache : # Virtual hosts Include /Applications/XAMPP/etc/extra/httpd-vhosts.conf the /etc/hosts file: 127.0.0.1 other1 127.0.0.1 other2 127.0.0.1 project I have tried : 127.0.0.1 project 127.0.0.1:3000 project 127.0.0.1 project:3000 I have also restarted the rails server and the XAMPP server many times after changes.

  • AWS lighttpd: Sending a copy of requests to test.

    - by Martin
    I have a load balanced service on AWS. So the ELB evenly distributes the load across my servers. Each server is running lighttpd that does logging and forwards the requests to my service (on the same machine). I have written a new version of the service. It is installed and running on an EC2 machine test1 (basically a mirror of our current server but the new service running instead of the original) and I have done some preliminary tests that look good. But what I would like to do is mirror a fraction of incoming traffic to the new version of the service so I can do some comparisons between an original version and the new version based on real traffic. Thus I was thinking I could modify one box behind the ELB to duplicate its traffic to the test1. I was thinking I could modify the configuration of lighttpd so that each request is mirrored/duplicated. i.e. the original service keeps responding as before but a mirror request is sent to test1 but the reply is just dropped). Unfortunately I have not been able to work this out. Any ideas on how I could mirror the requests from one box to itself and test1. Or any other ideas for testing.

  • Why is uploading to S3 so slow?

    I am using s3cmd to upload to S3: # s3cmd put 1gb.bin s3://my-bucket/1gb.bin 1gb.bin -> s3://my-bucket/1gb.bin [1 of 1] 366706688 of 1073741824 34% in 371s 963.22 kB/s I am uploading from Linode, which has an outgoing bandwidth cap of 50 Mb/s according to support (roughly 6 MB/s). Why am I getting such slow upload speeds to S3, and how can I improve them?

  • Application losing Printer within Terminal Services for remote users

    - by Richard
    Question: What I need to do is have a permanent link to a printer, normally only accessible through Terminal Services (Printer Redirect), to allow Sage Line 50 layouts to see that printer persistently, even after users have disconnected and reconnected to the Terminal Services session? Although the printer is accessible each time a user connects to the Sage Server via Terminal Services, it is given a different session number and therefore the Sage Layout sees it as a different printer. History behind question: Users using Terminal Services connecting to a Sage Server on a different site Using Sage Line 50 v 15 on that Server Users want to print invoices (sage layouts) locally Sage Server cannot see the users local printers, to get around this user uses the Print redirect features of Terminal Services The individual reports can be edited to point to a specific printer by default. This means the user just has to select an invoice and click print, then select the layout/report wanted and it auto prints that invoice to the default printer specified. The problem occurs because the layouts are edited to point to the users local printer "Ricoh 1018d (session#)", note the "(session#)" as this is the users local printer being redirected through the terminal services session. Users are able to print using the sage layouts once the default printer is setup within the layout and saved, but as soon as the users disconnects from the Terminal Services session and then reconnect in the morning go to print, it has lost the connection to that printer. I understand why its failed, because that the printer is on a per session basis and the layout would not be able to hold on to the connection from a previous session. Thanks in advance for any assistance...

  • Inexpensive, simple screen recording application for mac

    - by donut
    I am more and more consistently running into the need to create screencasts (record my screen) for clients to show them how to use programs or websites. Up until now I've been using Jing and it's been wonderful. But I would like something that can give me something less annoying than a .swf. A .mov or, best of all, something that plays without fuss on Mac and Windows. Also, the 5-minute limit is annoying, but not show stopping. Basically, I'd like to be able to actually give them the file on a CD or something instead of relying on whatever host I use staying up for eternity. To sum up, here's what I require: Record a portion or all of the screen. Records audio from mic while recording screen. Exports files easily playable on Mac and Windows (requiring Quicktime is okay, but not ideal) Will work on Mac OS 10.5+ Allows recording videos of at least 5 minutes. Text in recorded videos is easily readable when exported. Bonuses points for: Records videos greater than 5 minutes Exported videos will work in Windows Media player without any fuss. I haven't upgraded to Snow Leopard yet but I know it has some screen recording stuff built in but I don't know if it would be sufficient or not. The reason I say, "simple" is because most of the applications I've seen do much more than I need (I mean, Jing is nearly perfect for my needs) and cost more than I would like to spend.

  • Why do I get xfs_freeze "Operation not supported" error with ec2-consistent-snapshot? Debian Squeeze w/ext4 filesystem

    I'm running the following command: [root@somehost ~]# ec2-consistent-snapshot --aws-credentials-file '/some/dir/file' --mysql --mysql-socket '/var/run/mysqld/mysql.sock' --mysql-username 'backup' --mysql-password 'password' --freeze-filesystem '/dev/xvda1' vol-xxxxxx It returns this error: xfs_freeze: cannot freeze filesystem at /dev/xvda1: Operation not supported ec2-consistent-snapshot: ERROR: xfs_freeze -f /dev/xvda1: failed(256) snap-eeb66393 xfs_freeze: cannot unfreeze filesystem mounted at /dev/xvda1: Invalid argument ec2-consistent-snapshot: ERROR: xfs_freeze -u /dev/xvda1: failed(256) This is being run on Debian Squeeze with the ext4 Linux filesystem. Can anyone explain this error to me, or what might be its cause? When googling, I found information about it needing to be executed with sudo, but I'm performing the entire operation as root. I also found some posts about trying to run it after a CentOS upgrade using yum, but the situation appeared dissimilar. It's difficult to find things referring to this situation exactly. xfs_freeze is available for use on the filesystem. Is it possible that the filesystem, despite being ext4, somehow doesn't support freezing? Sorry if I've missed some bit of StackExchange etiquette with this post -- it's my first venture here!

  • Using hdparm for better performance on Web Servers

    - by Rishav
    I just heard about using hdparams to optimize the Hard Disk Performance of a server ? Is this common practice ? What file systems do you use ? I generally deploy on the second last release of Ubuntu for stability reasons, do you some other filesystems or use distributed file systems from the get go ? Do the hdparam settings change for different File systems ? I haven't tried this yet, so how much difference do changes like this make ?

  • Why is my Quicktime plugin transport bar black?

Any clue how to fix this? I've updated to the latest version of quicktime but it didn't help. I've also verified that this behavior is the same in both firefox and chrome.

  • How can I do an SELINUX filesystem relabel without rebooting first?

    - by Skaperen
    I can touch the file /.autorelabel and reboot and during the initialization coming back up it will do the SELINUX relabel for me. But I want to do this in a different situation where the system has just been copied to a hard drive image. I can chroot to the originating file tree, or chroot to the just populated device image and run it. I just can't find anything that says what to be run. This image is being made into an AMI on AWS EC2, and contains CentOS 6.3. But the time it takes to relabel is too long (6 minutes or more). I want to move the relabel to the image build where the extra time is not an issue (because it happens once instead of every time an AMI is launched). I can make this relabel be the very last thing just before the filesystem is unmounted for the last time until it becomes an AMI and will launch. I just need to know what to call to do it. I have searched man pages with no luck. I have searched system init scripts but where /.autorelabel is detected, it is unclear what is happening. Documents like http://www.centos.org/docs/5/html/5.2/Deployment_Guide/sec-sel-fsrelabel.html only tell how to do things that still really do the work after a reboot. I need to have the work doing BEFORE the "reboot" (unmount, build AMI, and launch ready to go). The big point is ... yes there will be a reboot ... but I want the relabel work to be done before that so it won't be done every time an AMI is launched (because it takes so long).
