• How to move Mdadm RAID drive (EBS based) to different AWS Instance

  - by Stanley

  We have a media-rich web application that is hosted on AWS. We have several Web Servers and we have an NFS server. On the NFS server (Linux server) we have several EBS volumes that are mounted and we've used mdadm to implement the different mounted volumes as a single RAID volume. The Web Servers simply access the NFS storage through a mount point. Amazon has now let us know that they will be performing power maintenance on this server in a couple of days time. Since all our media is on here it would render our site unusable for the hours while Amazon is working on it. We want to try and prevent this downtime. I was thinking that we can prevent server downtime by perhaps setting up a new server temporarily and attaching the EBS drives (raid volume) to that server and have our web servers point there during maintenance. This is a very high risk operation since this involves several terabytes of our production data. What would be the safe way to move over our logical raid drive (md0) to a new amazon instance? I was hoping that I could start with building the new server, mounting the ebs volumes and assembling the RAID partition using mdadm --assemble --scan before unmounting from the existing instance so that I can first test that everything works and thus having it mounted on two instances at the same time, but I don't believe that is possible with the way that filesystems work. How do I move a Linux software RAID to a new machine? suggests a way to move drives, but isn't really a cloud-based question. Perhaps there are simpler ways to prevent system downtime with our solution being hosted on the cloud? I have considered taking an EBS snapshot, but that tries to replicate all the many terabytes of mounted storage, so this is not a practical solution. Any ideas?

• Understanding NFS4 exports and pseudofilesystem

  - by Trevor Harrison

  I think I understand the way pre-NFS4 exports work, specifically the namespace of the exported point. (ie. export /mnt/blah on server, use mount server:/mnt/blah /my/mnt/point on client) However, I'm having a hard time wrapping my head around NFS4 exports. What I've been able to gather so far is that you export a 'root' by marking it with fsid=0, which you then import on the client side by referring to it as '/'. (ie. exportfs -o fsid=0 /mnt/blah on server, mount server:/ on client) However, after that, it gets a little weird. From my playing around, it seems I can't export anything else thats not under /mnt/blah. For example, exportfs /home/user1 fails when trying to mount from the client unless /mnt/blah/home/user1 exists on the server. If this is the case, what is the difference between exportfs /mnt/blah/subdir1 on server and mount server:/subdir1 on client and just skipping the exportfs and mounting whatever subdir of /mnt/blah you want? Why would you need to export anything other than the root? Its all in the same namespace anyway.

• Can't pin modified shortcuts to the Windows 7 task bar

  - by Coder

  I have a shortcut to a .bat file which I pin to the task bar using a workaround by using another icon and this seems to work. Now I make a copy of that shortcut, point it to a different .bat file, rename it, and I can't pin this one to the task bar. I have to find some other new unused icon to pin, pin it, then modify it manually. The other problem this causes is that windows seems to track which icons were pinned even if they are modified after the fact. As such, if I use media player as my dummy icon, pin it, then alter it's name and shortcut to point to a .bat file, I can't re-pin windows media player and if I select unpin from the windows media player, it unpins my shortcut to my .bat file. I can't believe how ridiculous this is. Is there a way to pin anything I want to the taskbar (ie. .bat file in my case) that does not cause problems like this? Is there an easy way I can copy an existing shortcut and modify it and re-pin it to the taskbar? The reason I want to copy it is because I start a .bat file (in particular git bash) and I set properties on the window like quick edit, increase the screen buffer and set it's position and size manually. I don't want to have to do this to every single icon I want to pin since they will be identical aside from the shortcut url.

• PHPMyAdmin works with https Only (not http)

  - by 01010011

  Hi I've been having a problem getting phpmyadmin to work consistently on my XP desktop and laptop computers for months now. When I type into Chrome's browser on both machines, localhost/phpmyadmin, I kept getting Error #1045 Access Denied for user at root@localhost (using password yes). Eventually, I realized that I had two (2) versions of mysql installed (XAMPP and MySQL Server 5.1) on both machines. So I uninstalled the MySQL Server 5.1I from the desktop and phpmyadmin worked. But when I uninstalled MySQL Server 5.1 from my laptop, it did not work. But I realized I could still get into MySQL Commandline Client using my password and that my databases were still intact. So I uninstalled and reinstalled XAMPP on the laptop and phpmyadmin worked after that. Now I have a new problem. On phpMyAdmin's home page has a message at the bottom: Your configuration file contains settings (root with no password) that correspond to the default MySQL privileged account. Your MySQL server is running with this default, is open to intrusion, and you really should fix this security hole by setting a password for user 'root'. So I located the following lines in config.inc.php file: /* Authentication type and info */ $cfg['Servers'][$i]['auth_type'] = 'config'; $cfg['Servers'][$i]['user'] = 'root'; $cfg['Servers'][$i]['password'] = ''; $cfg['Servers'][$i]['AllowNoPassword'] = true; and I just changed the last 2 lines as follows: $cfg['Servers'][$i]['password'] = 'mypassword'; $cfg['Servers'][$i]['AllowNoPassword'] = false; As soon as I did that and I tried to access phpmyadmin again, I got the Error #1045 message again, but when I tried https://localhost/phpmyadmin/ I got a red page saying this sites certificate is not trusted would you like to proceed anyway. And now it only works using https. I would really like to settle all my phpmyadmin problems once and for all so here are my questions: 1. Why does my laptop only access phpmyadmin via https? 2. How do I change my password in my configuration file? Also, if you have any other tips regarding phpMyAdmin, they are very welcome. Thanks in advance

• sudoer scheme for a web developer that retains future control of a server?

  - by Tchalvak

  Background I have a server that I'm looking to set up, and provide access to another web developer. I don't want to put many constraints on him, though I wouldn't mind isolating the site that he'll be developing from others on the server that I will develop. The problem Mainly what I want is to make sure that I retain control over the server in the future. I want to reserve the ability to create/promote/demote and other administrative functions that don't deal with web software. If I make him an admin, he can sudo su - and become root and remove root control from me, for example. What is a good setup for the sudoers file so that he can do things like: *install software (through apt-get) restart apache access mysql configure mysql/apache reboot edit web development configuration type files in /etc * And can't do things like: take away other admin permissions change the root password have control over other security/administrative functions Example sudoer files that accomplish something like that could be useful, I'm sure that people have needed to do this before.

• Linux PCIE Physical Bus Address

  - by Without me Its just Aweso

  I am working on designing a custom PCIexpress card. I am trying to write a kernel module that will DMA my custom card. Right now when i plug the card into linux no valid PCI device shows up (meaning I probably have a error on my end, i know) however, If I halt the system at startup in the bootloader (uboot) I am able to directly access the card as I know in uboot the physical memory address that is mapped to my device. Is there a way I can access the card in a simliar fashion in linux? Thanks, Stephanie

• How to execute files on LAN drives in a Windows Domain

  - by matnagel

  We have a very small LAN here, but some peolpe here think we need Active Directory, though nobody knows how to maintain it. I am not in the position to change this. How can I get full access (on Linux it would be "execute" rights) also for files on network drives (the files are just on another machine next room) My account is in the group Administrators on a windows 2003 server Domain Controller. I cannot open simple MS Access 2000 Databases or CHM Files from network drives in the lan How to do that? Some policy setting? I want to change that once. It is useless. We have no distinction between local or network files here. I would have to copy everything to a local drive and then do what I want.

• Easy way to restrict permissions in an elementary school computer lab?

  - by Andrew

  I'm putting together an elementary school computer lab. I have nine winxp pro machines that are not networked and do not have internet access (no money to do either). I've created separate student and admin accounts, and have the students set as limited users. However, I'm interested in further restricting their permissions. I want to make it such that they cannot: -delete any files, even just from their own profile -rename any files -move around the icons on the desktop -change any display settings -access a usb device without a password (they bring in their own from home which are chock-full of viruses) Oh, one last thing, they still have to be able to save word documents. Is this even possible? I can download software, but, like I said: no internet, no server.

• Domain Controller DNS Best Practice/Practical Considerations for Domain Controllers in Child Domains

  - by joeqwerty

  I'm setting up several child domains in an existing Active Directory forest and I'm looking for some conventional wisdom/best practice guidance for configuring both DNS client settings on the child domain controllers and for the DNS zone replication scope. Assuming a single domain controller in each domain and assuming that each DC is also the DNS server for the domain (for simplicity's sake) should the child domain controller point to itself for DNS only or should it point to some combination (primary VS. secondary) of itself and the DNS server in the parent or root domain? If a parentchildgrandchild domain hierarchy exists (with a contiguous DNS namespace) how should DNS be configured on the grandchild DC? Regarding the DNS zone replication scope, if storing each domain's DNS zone on all DNS servers in the domain then I'm assuming a DNS delegation from the parent to the child needs to exist and that a forwarder from the child to the parent needs to exist. With a parentchildgrandchild domain hierarchy then does each child forward to the direct parent for the direct parent's zone or to the root zone? Does the delegation occur at the direct parent zone or from the root zone? If storing all DNS zones on all DNS servers in the forest does it make the above questions regarding the replication scope moot? Does the replication scope have some bearing on the DNS client settings on each DC?

• Configure Iptables to allow a PHP-app accessing a port-nr

  - by Camran

  I have a php-application which connects to another app called Solr (database search engine). I can via this php app add/remove documents (records) from the Solr index. However, the Solr security is low, and anybody with the right port nr can access Solr and remove documents (records). I wonder, is it possible to ONLY allow my own php-app to have access to Solr somehow? Prefferably via Iptables. I am thinking I can only allow my own servers IP to that port, and it would solve my problem, because PHP is a server-side code. But I am not sure. About the Php-app: The website is a classifieds website, and when users wants to add or remove classifieds, they do so through a php app, which is this one. The app has a function which connects to solr and updates the database (index). I appreciate detailed answers... Thanks

• Is it possible to upgrade Server 2008 to RDP version 6.1?

  - by Dmitri K.

  Problem Server 2008 has RDP 6.0, Server 2008 R2 has RDP 6.1. My application works with RDP ActiveX control 6.1, but does not work with version 6.0 - generates access violation from mstscax.dll. Is there any way to upgrade Server 2008 (not 2008 R2) with RDP 6.1? More details: my application is written in Delphi, the ActiveX control was generated from mstscax.dll version 6.1.7601.17514. Target system where the application doesn't work, has mstscax.dll version 6.0.6002.18356. When the application tries to connect, it generate an access violation exception in mstscax.dll. The way I see it is a compatibility problem. I appreciate any ideas on how to resolve this.

• How to automatically enter username and password for network location in batch file?

  - by Phoenix Logan

  I have a batch file that copies files to a network location on WebDAV. The address looks something like this: \\xxxxxxxxx.net@SSL@2078\DavWWWRoot When I restart my computer, the batch file doesn't work and says "Access denied". Before a restart, it works, but it doesn't after the computer restarts. The problem is that it requires me to put in the username and password used to access the server. I have to browse to the server in File Explorer and sign in first. Even if I select the "Remember password" check box, it doesn't work. How can I get it to automatically sign in? I don't want to have to do this every time.

• Mac updated just now, postgres now broken

  - by Dave

  I run postgres 9.1 / ruby 1.9.2 / rails 3.1.0 on a maxbook air for local dev. It's all been running smoothly for months, (though this is the first time I've done development on a mac.) It's a macbook air from last year, and today I got the mac osx software update message as I have a few times before, and my system downloaded approx 450mb of updates and restarted. It now says it's on OSX 10.7.3. Point is, postgres has stopped working, when I start my thin server (mirror heroku cedar) as normal, and then browse to my rails app I get: PG::Error could not connect to server: Permission denied Is the server running locally and accepting connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"? What happened? After browsing around a few questions I'm still confused, but here's some extra info: Running psql from command line gives same error I can run pgadmin 3 and connect via it and run SQL no problems Running which psql shows the version as /usr/bin/psql I created a PostgreSQL user back when I got the mac (it's always been on lion) I've no idea why, almost certainly I was following a tutorial which I neglected to store in my notes. Point is I am aware there is a _postgres user as well. I know it's rubbish, but apart from a note on passwords, I don't have any extra info on how I configured postgres - though the obvious implication is that I did not use the _postgres user. Anyone have suggestions or information on what might have changed / what I can try to debug and fix? Thanks. Edit: Playing around based on this question and answer: http://stackoverflow.com/questions/7975414/check-status-of-postgresql-server-mac-os-x, see this string of commands: $ sudo su postgreSQL bash-3.2$ /Library/PostgreSQL/9.1/bin/pg_ctl start -D /Library/PostgreSQL/9.1/data pg_ctl: another server might be running; trying to start server anyway server starting bash-3.2$ 2012-04-08 19:03:39 GMT FATAL: lock file "postmaster.pid" already exists 2012-04-08 19:03:39 GMT HINT: Is another postmaster (PID 68) running in data directory "/Library/PostgreSQL/9.1/data"? bash-3.2$ exit

• Wireless to Wireless Transfer Slow on a Linksys WRT54GL

  - by Kyle Brandt

  The Situation: When I try to transfer a file from one computer to another that are both connected via wireless on a WRT54GL (in a office) with dd-wrt firmware I often get bad speeds. In generally they average around 100 kilobytes a second. Either computer can download via wireless from the Internet at at about 2 megabytes a second. The speed is slow with the transfer of one large file. There are about 20 other wireless networks that the computers can see, so there is a lot of noise, but I don't have the equipment to really monitor the frequencies well. But that still seems pretty slow. I thought maybe it was the transmit on each card, but even when they are 5 feet away with a line of sight I still get these speeds. According to Linux both cards are operating at 54g. My Questions: Is this normal for this sort of consumer level wireless equipment? Anything I can do to improve it? why is wireless to wireless transfer slow when everything else isn't? Whats steps might I take to figure out what is happening? For example, are lots of packets not making to the access point requiring retransmissions? Above all, I want to find out what the problem actually is. This may seem odd, but at this point I am more interested in understanding what the problem is than fixing it. What I have tried: I have tried messing with lots of settings. Different channels, xmit power, G-Only, none of which has made anything any better. I've also tried upgrading to newer dd-wrt firmware version and doing a reset to wipe out the settings.

• Connection timed out exception, why?

  - by Dheeraj Kumar Aggarwal

  I am developing an application which uses embedded tomcat server 7, and deploys a web application on embedded server. My application accesses the embedded webapp through Rest APIs, but my clients are getting Connection Timed Out exceptions and port is also not blocked. I never gets this exception when I install this application on my local machine. Some points: IP address is used in the host name part (They are able to access this IP address on other port) Port is not blocked We are using Apache HttpClient library to access the URL Timeout interval seems not to be an issue. What are the possible reasons for this exception Connection Timed Out? or How can I simulate this problem on my local machine? Any pointers would be helpful.

• How can I remove HTTP headers with .htaccess in Apache?

  - by Daniel Magliola

  I have a website that is sending out "cache-control" and "pragma" HTTP headers for PHP requests. I'm not doing that in the code, so I'm assuming it's some kind of Apache configuration, as suggested by this question (you don't really need to go there for this question's context) I don't have anything in my .htaccess files, so it's gotta be in Apache's configuration itself, but I can't access that, this is a shared hosting, I only have FTP access to my website's directory. Is there any way that I can add directives to my .htaccess files that will remove the headers added by the global configuration, or otherwise override the directive so that they're not added in the first place? Thank you very much Daniel

• Ubuntu Wubi "drive" failure; mount drive in XP?

  - by 618034

  Hi there, I installed the Wubi distribution of Ubuntu on a separate partition (which is silly, since why do I care if Windows can still manage the partition?) a few months back; it was pretty awesome, until Linux hosed. At this point, I can get Ubuntu to boot if I try really hard through grub, but once it does start, the screen is hosed, so no dice. At this point, I'd like to wipe it all and start over, but I need to get some stuff off the "disk". The Wubi install makes this difficult, since the "disk" is a flat file on an NTFS partition. I've done just about everything I can think of — I renamed the virtual disk .iso, mounted it with VirtualCloneDrive, then used whatever magic EXT3 (EXT4?) readers I could dig up on the Internet to parse the mount — but nothing's working. Can you offer any suggestions? The "disk" is currently in D:\ubuntu\disks\root.iso. Many thanks! (I may be high-latency at the moment, apologies if I don't address follow-ups quickly)

• What could cause TFTP reloaded Cisco `running-config` on 871 to fail?

  - by xtian

  Cisco CCP Write Configuration borked my 871w config while I was trying to setup port forwarding. I went through the basic steps to reconfig the router. I looked to see if I could just reset the router. Nope. I tested the 871's flash memory with fsck to see if there was hardware failure. Nope. Then I rewrote the minimal config for TFTP (which is the same for Cisco's CCP app.). Thne, I successfully uploaded a previously working running-config from Win Vista using SolarWinds TFTP Server, unfortunately the restore was not entirely successful. The old running config was saved to the 871's startup-config and I can login using console port. Some other things that are working are the hostname and welcome message but that's about it. Startup shows an error SETUP: new interface NVI0 placed in "shutdown" state after tftp. The missing light on the access point modem for ethernet link show the 871'a outside FE4 is not working. SO...what's the possible problem with reloading a previously working config (approximately 4 months with the same config) via TFTP? Is there something I can look for on the 871 to verify the config? Or on Vista to validate the config file itself before I transfer it? Or, is this there a common TFTP issue? UPDATE. I missed the instruction from Cisco's TFTP page to delete aaa lines from the config (although a video from a SuperUser user didn't make this point in his most excellent demo). There were several lines of this sort, I deleted them and uploaded again. However, they're back. I assume they're added automatically? [nope, see answer] UPDATE 2. The reload of previous settings was successful, but this error remains. I don't even know now if it was there before or not. It seems irrelevant to the question.

• Port Forwarding: Why do my local sites on 80 work but not those on 8080?

  - by Chadworthington

  I setup my router to forward port 80 to the PC hosting my web site. As a result, I am able to access this url (Don't bother clicking on it, it's just an example): http://my.url.com/ When i click on this link, it works: http://localhost:8080/tfs/web/ I also forward port 8080 to the same web server box But when I try to access this url I get the eror "Page Cannot be displayed:" http://my.url.com:8080/tfs/web/ I fwded port 8080 the same way I fwded port 80. I also turned off Windows Firewall, in case it was blocking port 8080. Any theories why port 80 works but 8080 does not?

• How soon does nginx's token bucket replenish when limiting at requests per minute?

  - by Michael Gorsuch

  Hi all. We've decided that we want to experiment and limit requests per minute instead of requests per second on our sites. However, I am confused by the burst parameter in this context. I am under the impression that when you use the 'nodelay' flag, the rate limiting facility acts like a token bucket instead of a leaky bucket. That being the case, the bucket size is equal to the burst parameter, and every time that you violate the policy (say 1 req/s), you have to put a token in the bucket. Once the bucket is full (being equal to the burst setting), you are given a 503 error page. I am also under the impression that once a violator stops going against the policy, a token is removed from the bucket at a rate of 1 token/s allowing him to regain access to the site. Assuming that I have the above correct, my question is what happens when I start regulating access per minute? If we chose 60 requests per minute, at what rate does the token bucket replenish?

• OpenVPN IPV6 Tunnel Radvd

  Hello.. I have an interesting question regarding ipv6 + openvpn.. My Version is OpenVPN 2.1.1 i have been given a native /64 ipv6 network ( for this example 2001:acb:132:acb::/64 ) The plan was/is, route this block through openvpn and into an office ( for testing purposes ) Soo to explain.. I have a Centos Box as the first linux "router" in a datacenter & a Ubuntu box as the second linux "router" in the office I have created a simple point-to-point tunnel using tun ( based off ipv4 address to start the tunnel ) I have assigned to Centos /sbin/ip addr add fed1::1/128 dev eth0 /sbin/ip addr add fed2::2/128 dev tun0 /sbin/ip route add 2001:acb:132:acb::/64 dev tun0 ## ipv6 Block down the tunnel /sbin/ip route add ::/0 dev eth0 ## Default out to Gateway I have assigned to Ubuntu /sbin/ip addr add fed1::3/128 dev tun0 /sbin/ip addr add fed1::4/128 dev eth0 /sbin/ip route add 2001:acb:132:acb::/64 dev eth0 ## ipv6 Block down to eth0 /sbin/ip route add ::/0 dev tun0 ## Default up the tunnel I have also included on both servers.. sysctl -w net.inet6.ip6.forwarding=1 Looks Good... right??? Wrong.. :( I am not able to ping fed1::1 from fed1::4 (Ubuntu) (can ping :4,:3,:2) However, i can ping fed1::1 fed1::2 from :3 ?????? ( very strange ) I am able to access the internet from any ipv6 interface on the Centos Box but clearly not from the Ubuntu box.. Further, i will eventually run radvd on the Ubuntu box eth0, and autoconf the network with ipv6 address's Anyone with some advice / tips to help me out.. ??? Cheers

• Mac .flac player that organizes folder structure? Can Songbird write to a ntfs drive?

  - by CT

  I have a bunch of music in .flac format on my pc. I would like to put that music on an external drive which I can access from both my Mac and PC at work. I have the drive formatted in NTFS using MacFUSE and NTFS-3G drivers. Through Finder I write to the drive fine. If I go to Show Info I see that I have custom access. I am trying to use Songbird to play said .flac files. I have Folder Management turned on. When I try to import to Library it errors out and says make sure drive exists and is writable. This seems like a permissions issue but I do not see how I could change them. If anyone knows of a good .flac player for the mac that also organizes folder structures like iTunes please let me know. This and the ability to write to a NTFS drive is what I am looking for.
