  • who has files open on a linux server

    - by Robert
    I have the fairly common task of finding who has files open on our Linux (Ubuntu ) file server in our Windows environment. We use Samba on the network and I use Putty from my workstation to establish a shell window to run bash scripts. I have been using something like this to find what files are open: (this returns a list of process ids with each open file) Robert:$ sudo lsof | grep "/srv/office/some/folder" Then, I follow up with something like this to show who owns the process: (this returns the name of the machine on the network using the IP4 protocol who owns the process) Robert:$ sudo lsof -p 27295 | grep "IPv4" Now I know the windows client who has a file open and can take action from there. As you can tell this is not difficult but time consuming. I would prefer to have a windows application I can run that would just give me what I want. So, I have been thinking about creating some process I can run on Linux that listens on a port and then returns a clean list of all open files with the IP address of the host who has the file open. Then, a small windows client application that can send the request on the port. It seems like this should be a very common need but I can not find anything like this that has been done before. Any suggestions?

  • Value of Itanium over x86_64 for Oracle Deployment

    - by Antitribu
    We are looking at a new environment to run our Oracle Database running on SUSE (potentially migrating to RedHat). Our database is approximately 100GB and performs adequately on our current hardware (x86_64) with approximately 6GB of ram allocated to it. We are growing quickly however and will require more performance shortly. Given the cost of Oracle licenses we would like to maximize the value from each license by choosing the most appropriate CPU to run the software on. The questions are: Are there substantial benefits to looking at Itanium hardware, are there any drawbacks? Is there a point where Itanium starts to scale out better? What are the long term support options for Itanium? Given the dominance of x86 would it be safer long term to stick with x86? On average what would be the performance benefit of implementing an Oracle database on Itanium over x86_64? Is this an issue at all or will other factors (IO/RAM) cap out first? If anyone can point me towards some solid documentation on comparisons between the two platforms that provides good case analysis of when to choose which I'm more than happy to accept that as an answer.

  • Dedicated server automatic backup solution

    - by Luigi
    I have a dedicated Ubuntu web server in a cloud environment, and I am looking for a nice way to do automated backups. I would like to backup some directories with web apps, and all my MySql databases. As for destination: make snapshots every two hours localy, and every six hours to a remote ftp server. Also delete backup archives older than seven days(localy + ftp), and notify on any problems by email. Now to achieve some of this functionality I use cron + shell script, and http://www.mysqldumper.net/, but really that doesn't answer my needs. Mysqldumper doesn't know automaticly about new databases, and shell script does not notify on problems. It's something I have to check out from time to time, and i don't have trust for. I googled a while, and seems like most people solve this stuff with shell scripts. Is this a method you can trust? Are there any web-gui tools, I'm missing? Maybe there is a smarter startegy for doing this? I'm a little bit confused.

  • Architecture for highly available MySQL with automatic failover in physically diverse locations

    - by Warner
    I have been researching high availability (HA) solutions for MySQL between data centers. For servers located in the same physical environment, I have preferred dual master with heartbeat (floating VIP) using an active passive approach. The heartbeat is over both a serial connection as well as an ethernet connection. Ultimately, my goal is to maintain this same level of availability but between data centers. I want to dynamically failover between both data centers without manual intervention and still maintain data integrity. There would be BGP on top. Web clusters in both locations, which would have the potential to route to the databases between both sides. If the Internet connection went down on site 1, clients would route through site 2, to the Web cluster, and then to the database in site 1 if the link between both sites is still up. With this scenario, due to the lack of physical link (serial) there is a more likely chance of split brain. If the WAN went down between both sites, the VIP would end up on both sites, where a variety of unpleasant scenarios could introduce desync. Another potential issue I see is difficulty scaling this infrastructure to a third data center in the future. The network layer is not a focus. The architecture is flexible at this stage. Again, my focus is a solution for maintaining data integrity as well as automatic failover with the MySQL databases. I would likely design the rest around this. Can you recommend a proven solution for MySQL HA between two physically diverse sites? Thank you for taking the time to read this. I look forward to reading your recommendations.

  • Using gentoo, how does one stick -9999 ebuild to a specific svn revision?

    - by hurikhan77
    As an example given the django-9999 ebuild, to match the developers environment I need to checkout R12120 from trunk. Installing Django manually is not option due to package management reasons. But there is also no ebuild in portage for 1.2 beta versions. So I did the following: ESVN_OPTIONS="-r12120" emerge -1a django Which installed the required revision from svn. But this is cumbersome in a way. Is there some way to define this statically per ebuild, eg something like: DJANGO_SVN_REV="12120" in make.conf. This would be much cleaner in my eyes. Because next time I need to rebuild django for whatever reason, I need to remember: "Oh I wanted this to stick to a specific revision" and next question will be "err, f&!#$?%, what was it again?" What's the best way to go here? Keep in mind: Manually installing packages without package manager knowledge is no option Working around with manual emerge variable prefixing is no option Setting up a /etc/portage/package.env would be a way to go (as described here) but that seems pretty unsupported and kludgy to me and thus unpreferable Modifying make.conf would be a way to go Keeping the ebuild in an overlay would be an option

  • Problem with single quotes in man pages

    - by Peter
    When I ssh into my Debian Lenny server and open a man page, single quotes appear to be messed up. Example from the man page of apt-get: If no package matches the given expression and the expression contains one of ´.´, ´?´ or ´*´ then it is assumed to be a POSIX regular expression, and it is applied to all package names in the database. Any matches are then installed (or removed). Note that matching is done by substring so ´lo.*´ matches ´how-lo´ and ´lowest´. If this is undesired, anchor the regular expression with a ´^´ or ´$´ character, or create a more specific regular expression. I'm on Mac OS X and using xterm. If I use Terminal, the problem doesn't happen. My locale is configured correctly as far as I can see: $ locale LANG=en_US.UTF-8 LC_CTYPE="en_US.UTF-8" LC_NUMERIC="en_US.UTF-8" LC_TIME="en_US.UTF-8" LC_COLLATE="en_US.UTF-8" LC_MONETARY="en_US.UTF-8" LC_MESSAGES="en_US.UTF-8" LC_PAPER="en_US.UTF-8" LC_NAME="en_US.UTF-8" LC_ADDRESS="en_US.UTF-8" LC_TELEPHONE="en_US.UTF-8" LC_MEASUREMENT="en_US.UTF-8" LC_IDENTIFICATION="en_US.UTF-8" LC_ALL= I'm not sure what's wrong with my environment, and I have no idea what to check next. I'd appreciate help.

  • Binding to LDAPS using PHP failing

    - by Sean
    We've finally set-up our server to accept ldap SSL connections thanks to another question answered by a helpful member. Our problem now is that when attempting to bind to ldap using the below simple PHP script, we constantly fail. Binding using ldap instead of ldaps works just fine using the script so I know the ldap is enabled. The catcher is that while using LDP.exe, we can successfully connect and bind to ldap on port 636 using a secure connection. The script we are failing with is below: <?php $ldap = ldap_connect("ldaps://localhost"); $username="user"; $password="pass"; if($bind = ldap_bind($ldap, $username,$password )) echo "logged in"; else echo "fail"; echo "<br/>done"; ?> We've also attempted inputting the username as "user@domain" or "domain/user" with no success. It seems I'm forever having LDAP/Cert questions. Our environment is Server 2008.

  • How can I track down the cause of ext3 filesystem corruption?

    - by Jon Buys
    We have a VMware vSphere 5 environment running CentOS 5.8 virtual machines. In the past two weeks we have had five incidents of virtual machines having a filesytem become corrupt, requiring an fsck to repair. Here is what we see in the logs: Nov 14 14:39:28 hostname kernel: EXT3-fs error (device dm-2): htree_dirblock_to_tree: bad entry in directory #2392098: rec_len is smaller than minimal - offset=0, inode=0, rec_len=0, name_len=0 Nov 14 14:39:28 hostname kernel: Aborting journal on device dm-2. Nov 14 14:39:28 hostname kernel: __journal_remove_journal_head: freeing b_committed_data Nov 14 14:39:28 hostname last message repeated 4 times Nov 14 14:39:28 hostname kernel: ext3_abort called.

So far we have been unable to reproduce the problem, or identify a root cause. After we had a few servers have this problem, we assumed that there was an issue with the template, so we scrapped all VM's cloned off of the template, destroyed the template, and built a new template from scratch, installed from a newly downloaded CentOS ISO. We use HP EVA SAN's for datastores, and moved from a 4400 to a 6300 after the first problem. Since the move and rebuilding new virtual machines we have seen the issue twice. On one VM we shut down the server, removed two virtual CPUs, and booted it back up again, the problem presented itself almost immediately. On the other VM, we rebooted it, and the problem happened a half hour later. Any tips or pointers in the right direction would be appreciated.

  • vmdk Recovery after migration from 3.5 to 4 and fallback tentative.

    - by olgirard
    Hy, I've tryed to migrate some VM from my 3.5i environment to a brand new vSphere 4.0 U1. The two platforms are running simultaneously, sharing the same SAN. I Migrate my VM by stopping it, unregistering in vcenter (esx ver. 3.5, i call it esx3), register in vSphere (esx ver. 4, i call it esx4), and migrate upgrade virtual hardware before powering it up (First mistake). vMotion was enabled on esx4, seem to be a second mistake. After a day or so, i encountred problems joigning the esx server (esx4) and decided to unregister my server for esx4 and fallback to esx3. esx3 refused to boot, i supposed this was due to virtual hardware in Version 7 so i recreated a new VM pointing to the vmdk of the old VM. Everithing seemed fine until i log into the server and discover that i was running on the original disk ith every snapshots ignored even those created on esx3. I tried to reboot VM on esx4 but VM doesn't power up because "The parent virtual disk has been modified since the child was created". I've got a copy of a later state of the drive but generated between two snapshots (ovf generated with canverter standalone) as a backup. Do i have a chance to recover at least some files on the virtual drive or (as i tink) all is played, i've done enought mistakes for this time. Thanks for your help.

  • Is encryption really needed for having network security? [closed]

    - by Cawas
    I welcome better key-wording here, both on tags and title. I'm trying to conceive a free, open and secure network environment that would work anywhere, from big enterprises to small home networks of just 1 machine. I think since wireless Access Points are the most, if not only, true weak point of a Local Area Network (let's not consider every other security aspect of having internet) there would be basically two points to consider here: Having an open AP for anyone to use the internet through Leaving the whole LAN also open for guests to be able to easily read (only) files on it, and even a place to drop files on Considering these two aspects, once everything is done properly... What's the most secure option between having that, or having just an encrypted password-protected wifi? Of course "both" would seem "more secure". But it shouldn't actually be anything substantial. I've always had the feeling using any kind of the so called "wireless security" methods is actually a bad design. I'm talking mostly about encrypting and pass-phrasing (which are actually two different concepts), since I won't even consider hiding SSID and mac filtering. I understand it's a natural way of thinking. With cable networking nobody can access the network unless they have access to the physical cable, so you're "secure" in the physical way. In a way, encrypting is for wireless what building walls is for the cables. And giving pass-phrases would be adding a door with a key. So, what do you think?

  • Router recommendation to virtualize 800 IPs

    - by delerious010
    I've recently been looking at getting some new load balancers for our environment as we are expecting to double our client base in the next 12 months. Currently we have 400 public IPS serving 800 clusters ( 2 clusters / IP due to ports ) on Coyote Point Balancers, and distributing connections to 3 web servers serving about 6GBytes outgoing, 2Gbytes in per day. If we double, this would be about 800 IPs, possibly 1600 clusters, and about 6 servers per cluster ( for a total of 9600 so called "real servers" using Barracuda's lingo ). Due to the amount of clusters, most solutions I've looked at ( Coyote, Barracuda, Loadbalancer.org ) seem to be unsure whether they'll be able to handle our planned growth, mostly due to health checks performed on the servers ... which makes total sense when you think of it. So the fine folk at loadbalancer.org recommended that we may be better off offload the 400-800 public IPs, which we require for SSL eCommerce solutions, over to a forward facing router. From that point on, the router could do some mangling to route EXT_IP:443 to INT_IP:INT_PORT which would then allow us to reduce the Load Balancer configuration to 1 or 2 clusters, thus resolving the health check problem. Does this idea make sense to yall ? Or would you have other recommendations to make ? Secondly, what router would you recommend for such an undertaking ? I'd be looking at something that has some form of failover mechanism built in. On a totally unrelated note, I've got to admit that I'm extremely pleased with the responses I got from loadbalancer.org. Their responses to my inquiries were surprisingly helpful ( i.e. I didn't feel as if I was taking to a sales guy trying to push something ). ( No I don't work for them, and sadly nor are they sending me free gear ).

  • Overheating Toshiba Satellite L300

    - by ldigas
    A coleague of mine's having trouble with his new Toshiba Satellite L300 ... I tool a kook at it, and indeed it's hot as hell. I couldn't hold my hand on it for too long. He says it also has a tendency to turn itself off (WinXP 32bit running) with no forewarning. Hasn't happened to me while I was using it, but that wasn't long anyways. The first guess was it was too dirty ... problem is it's new, came out of a package a quarter of a year ago. Kept in a clean environment (office). Looks clean. No dust in sight. Second guess is that the fan wasn't working properly, cause indeed it has intervals of working, and non working. But when I listen to it, it sounds like normal usage. I took a SpeedFan measurement, and it reports temp. up to 85 Celsius ... which is definitely too high. Anyone knows what else I could do to it ? It is under warranty and it will go to the service, but I thought if there is something we can do, as to avoid carrying it there / be without it for a week ...

  • VirtualBox problems writing to shared folders (Guest Additions installed)

    - by vincent
    I am trying to setup a shared folder from the host (ubuntu 10.10) to mount on a virtualized CentOS 5.5 with Guest Additions (4.0.0) installed (Guest addition features are working ie. seamless mode etc.). I am able to successfully mount the share with: mount -t vboxsf -o rw,exec,uid=48,gid=48 sf_html /var/www/html/ (uid and guid belong to the apache user/group) the only problem is that once mounted and I try to write/create directories and files I get the following: mkdir: cannot create directory `/var/www/html/test': Protocol error I am using the proprietary version of VirtualBox version 4.0.0 r69151. Has anyone had the same problem and been able to fix it or has any idea how to potentially fix this? Another question, the reason for setting this up is this. Our production servers are on CentOS 5.5 however I am a great fan of Ubuntu and would like to develop on Ubuntu rather than CentOS. However in order to stay as close to the production environment I would like to virtualize CentOS to use a web server and use the shared folder as web root. Anyone know whether this isn't a good idea? Has anyone successfully been able to set this up? Thanks guys, your help is always much appreciated and if you need any more information please let me know.

  • probems using ssh from cron

    - by Travis
    I am attempting to automate a script that executes commands on remote machines via ssh. I have public key authentication setup between the machines using ssh-agent. The script runs fine when executed from the command prompt. I suspect my problem is that cron isn't starting the ssh-agent due to it's minimalist environment. Here is the output when I add the -v flag to ssh: debug1: Authentications that can continue: publickey,gssapi-with-mic,password debug1: Next authentication method: gssapi-with-mic debug1: Authentications that can continue: publickey,gssapi-with-mic,password debug1: Authentications that can continue: publickey,gssapi-with-mic,password debug1: Next authentication method: publickey debug1: Offering public key: /home/<user>/.ssh/id_rsa debug1: Server accepts key: pkalg ssh-rsa blen 149 debug1: PEM_read_PrivateKey failed debug1: read PEM private key done: type <unknown> debug1: Trying private key: /home/<user>/.ssh/id_dsa debug1: Next authentication method: password debug1: Authentications that can continue: publickey,gssapi-with-mic,password Permission denied, please try again. debug1: Authentications that can continue: publickey,gssapi-with-mic,password Permission denied, please try again. debug1: Authentications that can continue: publickey,gssapi-with-mic,password debug1: No more authentication methods to try.

  • AWS document on number of databases allowed on an Amazon RDS instance

    - by user35042
    At the Amazon RDS FAQ there is the question "What is a database instance (DB Instance)?". The entire answer (as of mid-June 2012) is: You can think of a DB Instance as a database environment in the cloud with the compute and storage resources you specify. You can create and delete DB Instances, define/refine infrastructure attributes of your DB Instance(s), and control access and security via the AWS Management Console, Amazon RDS APIs, and Command Line Tools. Multiple MySQL databases or SQL Server databases (up to 30) or Oracle database schemas can be created on a given DB Instance. The last part of that quote, "Multiple MySQL databases or SQL Server databases (up to 30) Oracle database schemas" I interpret to mean that you can have an "unlimited" number of databases on an RDS MySQL or Oracle instance but only 30 databases on an MS SQL Server instance ("unlimited" meaning not limited by the RDS infrastructure itself). This was asked in the Stackoverflow question Does Amazon RDS support multiple databases per instance?. The answer quoted an older version of the FAQ. What I am looking for is an Amazon document that clarifies this question, or else someone who has experience using Amazon RDS who can attest what the situation actually is.

  • Remote assistance from Remote Desktop sessions: unable to control

    - by syneticon-dj
    Since Remote Control (aka Session Shadowing) is gone for good in Server 2012 Remote Desktop Session hosts, I am looking for a replacement to support users in a cross-domain environment. Since Remote Assistance is supposed to work for Remote Desktop Sessions as well, I tried leveraging that for support purposes by enabling unsolicited remote assistance for all Remote Desktop Session Hosts via Group Policy. All seems to be working well except that the "expert" seems to be unable to actually excercise any mouse or keyboard control when the remote assistance session has been initiated from a Remote Desktop session itself. Mouse clicks and keyboard strokes from the "expert" session (Server 2012) seem to simply be ignored even after the assisted user has acknowledged the request for control. I would like to see this working through RD sessions for the support staff due to a number of reasons: not every support agent would have the appropriate client system version to support users on a specific terminal server (e.g. an agent might have a Windows Vista or Windows 7 station and thus be unable to offer assistance to users on Server 2012 RDSHs) a support agent would not necessarily have a station which is a member of the specific destination domain (mainly due to the reason that more than a single domain's users are supported) what am I missing?

  • Firefox 3.6 and above. Always show one tab even if all tabs are closed like Firefox 3.0

    - by Jayapal Chandran
    I very much got used to Firefox 3.0. In that, to free the memory, I close all tabs but still the main Firefox window does not close. But in Firefox 3.6 and later if I want to close all tabs and if I do so then Firefox totally exists. This is not the case with 3.0. How to stop Firefox from not closing the main process even if I close all threads (tabs)? The autocomplete feature in the address bar of Firefox 3.6 and greater is in a dark blue color which makes me very much annoyed. With my environment and the monitor glare that is inducing anger in me, so how the color be changed to be like Firefox 3.0? Because you know that black and white are a neutral and good combination and since I have been working in Firefox 3.0 (and earlier versions) for a long time this new color change and other uncomfortable options are making me sick. To check CSS3 I need to use Firefox 3.5 and greater. Besides I like Firefox because it includes the W3C's recommendations so I can learn and test new recomendations from W3C.

  • Why is my global security group being filtered out of my logon token?

    - by Jay Michaud
    While investigating the effects of filtered tokens on my file permissions, I noticed that one of my global security groups is being filtered in addition to the regular system-defined filtered groups. My Active Directory environment is a single-domain forest on the Windows Server 2003 functional level. I'll call the domain "mydomain.example.com". I am logged onto a Windows Server 2008 Enterprise Edition machine (not a domain controller) as a member of the "MYDOMAIN\Domain Admins" group and the "MYDOMAIN\MySecurityGroup" global security group (among others). When I run "whoami /groups" from an elevated command prompt, I see the full list of groups to which my account belongs as expected. When I run "whoami /groups" from a regular, non-elevated command prompt, I see the same list of groups, but the following groups are described as "Group used for deny only". BUILTIN\Administrators MYDOMAIN\Schema Admins MYDOMAIN\Offer Remote Assistance Helpers MYDOMAIN\MySecurityGroup Numbers 1 through 3 above are expected based on Microsoft documentation; number 4 is not. The "MYDOMAIN\MySecurityGroup" global security group is a group that I created. It contains three non-built-in global security groups, and these security groups contain only non-built-in user accounts. (That is, I created all of the accounts and groups that are members of the "MYDOMAIN\MySecurityGroup" global security group.) There are other, similar groups of which my account is a member that are not being filtered out of my logon token, and this group is not granted any specific user rights in the security settings of this computer or in Group Policy. What would cause this one group to be filtered out of my logon token?

  • IIS 6 getting "Page Not Found" after applying SSL

    - by Dominic Zukiewicz
    I am setting up SSL certificates on a development environment using IIS 6 on W2k3. I have a directory called login with a single page login.asp which I would like only viewable over SSL. So before installing or applying SSL permissions, the page is viewable through a browser. I can browse the page and it redirects etc. and all is good. However Basic Authentication is Base64 encoded so I want to secure the traffic from this page only. I have created a dummy certificate in makecert, installed it and added it to IIS. IIS is happy that it is trusted. I have selected the directory of login and child files to "Require SSL channel". When I refresh my browser on login/login.asp I get a "404: Page Not Found" in IE 8. So 2 issues here The page is now unviewable when using HTTPS. They must manually type the HTTPS (minor inconvenience for now) If I turn off "Require SSL Channel" from IIS, it works again. What part of the process am I missing as I have followed several tutorials on installed SSL certificates, but still come across this barrier.

  • Small Business HP Virtualisation and iSCSI SAN Options

    - by Robin Day
    We are a small business that hosts our core product on a number of HP servers. Our core production setup is 1x HP DL380, high powered for a SQL Server Database 1x HP DL360, mid powered for our core application server 6x HP DL320, low powered for our front ends We run our training / testing / support systems on a similar setup, the servers are just older and less powerful. Unfortunately this is now causing us issues as the system has grown beyond the capabilities of these older servers. Upgrading these servers would be expensive and we believe that virtualisation is probably the way to go for the future. Locally we run a number of test / dev environments on ESXi using Direct Storoage on a couple of high powered DL360's and these are performing fairly well. We're thinking that instead of replacing all of our test servers that we can implement an iSCSI SAN and one or two high powered hosts. Hopefully looking that when it comes to replace our live servers as well that we can just expand the virual environment to cope. So my question is... Can anyone offer any advice on some suitable options? We have generally always been extremely happy with HP servers, all of our kit is currently HP, therefore our preference would be to stick with HP, however, I'm always happy to hear about other options. I'm hoping that initially a budget of around 15-25k (GBP) would be suitable, this could potentially be increased if I had confidence that the system would pave the way for a cost effective upgrade of our live systems in the future as well. I am new to SAN's and my only real experience is playing with OpenFiler on some old desktops. I think iSCSI should be suitable, but I've not done any research into how SQL server may perform. I've had a browser through HP's sites and see plenty of information about EVA, MSA, LeftHand, etc. However, from looking at all that, I don't see which options would be best and more importantly I don't know exactly what I would need to buy. Any help, links, opinions would be much appreciated. Thanks

  • TCP: Address already in use exception - possible causes for client port? NO PORT EXHAUSTION

    - by TomTom
    Hello, stupid problem. I get those from a client connecting to a server. Sadly, the setup is complicated making debugging complex - and we run out of options. The environment: *Client/Server system, both running on the same machine. The client is actually a service doing some database manipulation at specific times. * The cnonection comes from C# going through OleDb to an EasySoft JDBC driver to a custom written JDBC server that then hosts logic in C++. Yeah, compelx - but the third party supplier decided to expose the extension mechanisms for their server through a JDBC interface. Not a lot can be done here ;) The Symptom: At (ir)regular intervals we get a "Address already in use: connect" told from the JDBC driver. They seem to come from one particular service we run. Now, I did read all the stuff about port exhaustion. This is why we have a little tool running now that counts ports and their states every minute. Last time this happened, we had an astonishing 370 ports in use, with the count rising to about 900 AFTER the error. We aleady patched the registry (it is a windows machine) to allow more than the 5000 client ports standard, but even then, we are far far from that limit to start with. Which is why I am asking here. Ayneone an ide what ELSE could cause this? It is a Windows 2003 Server machine, 64 bit. The only other thing I can see that may cause it (but this functionality is supposedly disabled) is Symantec Endpoint Protection that is installed on the server - and being capable of actinc as a firewall, it could possibly intercept network traffic. I dont want to open a can of worms by pointing to Symantec prematurely (if pointing to Symantec can ever be seen as such). So, anyone an idea what else may be the cause? Thanks

  • Debootstrap Ubuntu over NFS leads to mknod I/O error

    - by Aaron B. Russell
    Hi everyone, I'm trying to prepare an Ubuntu environment for a diskless machine that will PXE boot and mount an NFS share as it's root. I've currently got another Ubuntu machine mounting the NFS share and I'm trying to debootstrap into it, but it has trouble creating devices over NFS: root@kimiko:~# mount | grep Seiuchi 192.168.0.203:/mnt/user/Seiuchi on /mnt type nfs (rw,addr=192.168.0.203) root@kimiko:~# debootstrap --arch i386 maverick /mnt http://gb.archive.ubuntu.com/ubuntu/ mknod: `/mnt/test-dev-null': Input/output error E: Cannot install into target '/mnt' mounted with noexec or nodev My NFS rule on the unRAID server is 192.168.0.201/32(rw,no_root_squash,sync). I don't have the noexec or nodev options set. I've not got much experience with NFS, so I'm probably missing something basic in the way I'm sharing this, but my attempts at Googling for an answer isn't really turning anything useful up. Does anyone have suggestions on what I might have missed or maybe relevant docs? Edit: Creating normal files (and directories) works just fine, I just can't create devices... root@kimiko:/mnt# mkdir foo root@kimiko:/mnt# cd foo root@kimiko:/mnt/foo# touch bar root@kimiko:/mnt/foo# mknod quux c 4 64 mknod: `quux': Input/output error root@kimiko:/mnt/foo# ls bar

  • Load balancing a Windows File Share using HA-Proxy

    - by NathanE
    After pulling my hair out over DFS I just had this weird and potentially dangerous idea come into my head whereby, just possibly, I might be able to use HA-Proxy to load balance a file share between servers. I've done some remedial packet traces and it does appear that TCP port 445 is the only thing involved in using Windows file sharing. I've always thought for many years that UDP 139, 135 etc were also involved in at least establishing the connection - but apparently not! So I setup a basic test: listen SMBTest *:445 mode tcp server Smb1 172.16.61.201:445 server Smb2 172.16.61.202:445 And you'll never guess what... it works??? (!) Now obviously there is the whole concern about synchronisation between the file servers (of course). That could easily be taken care of with a little bit of Robocopy script. And considering I only need a HA read-only file share there wouldn't be any issues with regard to file locking etc. Can anyone tell me if what I'm playing with here is fire? I really didn't think it would work at all and now I'm a little shocked. What would be the downsides? Could this be relied upon for a production environment?

  • How to point a subdomain to local server with dynamic IP

    - by jlego
    I see there are many related questions to this one, however the answers given seem to be a little vague for a novice like me. I've got a dedicated LAMP stack running Fedora 16 locally on my home network. Everything works fine internally. I can access the Apache server from other machines on the network using the internal IP in a browser. I'm using the stack for a local file server as well as a development environment for websites. There are a couple of reasons why I would like the development sites hosted on the machine to be available publicly. 1.) I use a CMS that has paid add-ons which allows you to assign the paid license to a domain. I can't develop with paid add-ons on the closed dev server. 2.) I would occasionally like for clients to be able to view the site dev at late stages before it goes live. I have a domain (foo.com, and I want to point a *sub*domain (dev.foo.com) to the local server. I know this is best accomplished with a Static IP, however my IP from my ISP is Dynamic and I don't think there is any way to change that. From what I have read, services like ZoneEdit & DynDNS are supposed to be able to accomplish this, but I have tried both and found it very confusing. Also the server is behind a router and I have also read that you need to set up DDNS(?) in your router, that many routers have presets for these services, and I've found that DynDNS is the only one my router seems to support.
