  • Windows7: Howto force a "do you really want to shutdown?" dialog

    - by Vokuhila-Oliba
    Sometimes I wanted to choose "logout current user", but then I hit "Shutdown" by accident. Nearly everywhere else Windows7 is asking "do you really want to do this Yes/No". But that's not the case when I hit the "Shutdown" button. Windows7 shuts down immediately without giving me the chance to correct my mistake. Q1: So I am wondering why Windows7 shuts down immediately without asking "really do that?" in this case. Q2: Is there a way to change this behavior? E.g. Could I force Windows7 to display a dialog asking "Do you really want to shutdown ?". ADDED: I am running Windows7 Professional 64bit. ADDED: I tried to change this behavior with the policy editor. It seems to be very easy to completely remove the Shutdown button from the start menu. But I couldn't find an entry to turn on such a Yes/No dialog.

  • How to fix UNMOUNTABLE_BOOT_VOLUME (0x000000ED) on my Windows XP DELL laptop?

    - by Neil
    I have a Dell Latitude D410. Running Windows XP. I am receiving the STOP: 0x000000ED (0X899CF030,0XC0000185,0X00000000,0X00000000) Blue screen. Initially, I tried everything specified with the Microsoft KB articles. At this time, I was able to boot into the general safemode. I pulled the hard drive and was able to run chkdsk on it- it noted that it had fixed some errors, but I was still unable to boot. I put a brand new hard drive in the laptop. Windows XP installation worked up until the reboot, at which time the exact same error message came back up. What I have tried (all since the new hard drive was installed): chkdsk /R All suggested solutions in Microsoft KB articles Reseating RAM Opened laptop, reseated all connectors, looked for signs of damage (saw none) Reset BIOS options to default Ran the basic Dell diagnostics I have looked at the current entry:How can I boot XP after receiving stop error 0x000000ED - I am currently in the process of downloading the Ultimate Boot CD to use as a test, but I am not holding out a lot of hope as I really doubt this brand new Hard Drive is bad. Can anyone think of other areas I am missing? Ran MEMTEST86+ V4.10 for 15 passes (overnight). 0 Errors EDIT: FORMATTING

  • Why does my router log crazy amounts of blocked traffic on port 1701?

    - by Vlad Seghete
    I have a 2701HGV-B 2Wire modem and router (AT&T). The log is basically full with entries similar to the following with a time between a fifth and a third of a second between entries: src=86.156.7.170 dst=xxx.xxx.xxx.38 ipprot=17 sport=6882 dport=1701 Unknown inbound session stopped src=58.176.22.252 dst=xxx.xxx.xxx.38 ipprot=17 sport=21573 dport=1701 Unknown inbound session stopped src=91.221.6.250 dst=xxx.xxx.xxx.38 ipprot=17 sport=25902 dport=1701 Unknown inbound session stopped ... where the source IP will be different for every entry. The entries accumulate constantly, every single second that the router is on several of them appear in the log. The destination is the WAN address for my router. I understand that this is somehow related to VNCs, but I don't know enough to figure out why my router is getting bombarded with requests for a VNC session. Is there anything fishy going on or is this normal? If it is normal, how do I keep these entries from spamming my log files? Since there's about two or three of them every second, everything else gets drowned out.

  • Apache Virtual Host with directory aliases

    - by brechtvhb
    Hi, I'm trying to set up a dynamic virtual host in apache with a directory alias pointing to a difirent path for every domain. Here's what I'm trying to achive. Say I have 2 domains: * www.domain1.com * www.domein2.com I want both to point to the same index.php file (C:/cms/index.php). Now the hard part ... I want directories or certain file types to point to a diffirent path for each domain. Example: * www.domain1.com/layout -> C:/store/www.domain1.com/layout * www.domain2.com/layout -> C:/store/www.domain2.com/layout * www.domain1.com/image.png -> C:/store/www.domain1.com/image.png * www.domain2.com/image.png -> C:/store/www.domain2.com/image.png However the admin directory should point to the same path again for all sites * www.domain1.com/admin -> C:/cms/admin * www.domain2.com/admin -> C:/cms/admin Is there a way to achieve this kind of behaviour in apache 2.2 without having to create a virtualhost entry for each new domain?

  • How to get Subversion repository from svn:// and https://?

    - by Hikari
    I know these are noob questions, but I never got my own Subversion running before and I'm kinda lost. I installed VisualSVN in Windows, but it doesn't support svn:// protocol by default, only HTTP or HTTPS. It is working fine over HTTP, and I'm able to manage it from its management tool, see its repositories and get their HTTP-based URL, and from that I'm able to use Tortoise to check out and check in. I'm able to check out from a repository URL using Tortoise: http://Main:90/svn/HikariKrumo/ But I need svn:// protocol for Redmine to access it. Redmine says to support http:// but it reports this error message: The entry or revision was not found in the repository.. And I need HTTPS to access it from Internet. If I can get Redmine to access it from svn:// I can just configure it to use HTTPS in place of HTTP, and I hope it all to works. I like VisualSVN because of its management tool, but I can use another Subversion distro if needed, as long as it supports svn:// and https://. I'm getting crazy on it because it should be simple but I can't get it to work.

  • sendmail appends server name to external domains when relaying

    - by Chris
    My server is set to send all email to a corporate relay server. For the company domain, it works perfectly. I've recently found emails being sent to an outside domain are getting the hostname of my server appended to the email prior to being sent. Here is the log entry for one such attempt. Nov 6 09:46:45 myservername sendmail[45023]: rA6EkjiI045023: [email protected], delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30590, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (rA6Ekj2g045037 Message accepted for delivery) Nov 6 09:46:45 myservername sendmail[45061]: rA6Ekj2g045037: to=<[email protected]>, delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=120885, relay=relay.company.com [x.x.x.x], dsn=2.0.0, stat=Sent (ok: Message 342335947 accepted) Notice the email address difference between it being accepted by my server for delivery (correct email address), and being sent and accepted by the corporate relay (incorrect with server name appended). To make it more interesting, the application on my server uses email for user account verification/activation. In August, this particular user was able to register his account and activate it. I have made no configuration changes to mail since setting the server up over a year ago. DNS is also a corporate service. I've never touched my /etc/resolv.conf configuration. domain company.com nameserver <ip1> nameserver <ip2> search myservername Thanks!

  • How do I serve Ruby on Rails applications on Windows Server 2008?

    - by Adam Lassek
    I have spent the last several hours attempting to get Ruby on Rails running on a Windows server with no luck. At first I tried configuring a test application through IIS7's FastCGI support, but the documentation for this is not very good. I've been following this blog entry, and this one, and this one, and this one but everything seems to be missing major steps, or are out of date. And every article keeps linking back to this Howto from rubyonrails.org that doesn't exist. The sense that I'm getting is that even if I manage to make this work, IIS' FastCGI isn't good enough to use in a production environment anyway. So it looks like my best bet is to setup a reverse proxy in IIS that points to Apache & Mongrel/Passenger using ARR and UrlRewrite. Is there anybody else out there stuck deploying a Rails application on a Windows stack? Am I on the right track? Can you give me a better idea of how to configure this? I believe Plesk already installed an instance of Apache/Tomcat running on this server using a different port, so adding another virtual host shouldn't be difficult; the hardest part seems to be setting up the reverse proxy through IIS.

  • 2.6.9 Kernel on virtual server (non upgradable) - any expected problems?

    - by chris_l
    Hi, I'm considering to rent a virtual server (for me personally). The product I'm currently looking at offers IMO fair pricing, very good hardware etc. The only problem is, that I won't be able to do an upgrade to a newer kernel than 2.6.9 (running Debian Etch). Also, I can't install my own kernel modules. (The server runs with Virtuozzo, so as far as I understand it, it just does some chroot instead of a real virtualization (?)) I want to run GlassFish, Postgres, Subversion, Trac and maybe some other things on it. It will also have to employ a firewall, and provide OpenSSL for https. Ideally, it would also be able to do AIO (asynchronous IO), which could speed up some server I/O. Should I expect problems with that old kernel version, in conjunction with the software I want to install (I'd like to use current versions of the software)? One thing I already found out, is that you can't do everything with iptables, since some kernel modules are missing/things are not build into the kernel. GlassFish v3 appears to run fine at first glance. I was able to test the server for a few hours. Installing my whole setup wasn't feasible in that time, but what I can say is, that it's amazingly fast for an entry-level vserver, especially hard disk and network performance (averaging at ca. 400MBit/s). So if the kernel won't be a problem, I'd really like to take it. Thanks, Chris PS Exact kernel version: 2.6.9-023stab051.3-smp

  • IIS 6.0 https not working "connection was reset"

    - by cad
    Application Server Windows Server 2003 SP2 with IIS 6.0 IIS has a "Default Web Site" (port 18000, ssl 443, ID=1) with a certificate created by me. I have an specific site called "scj.galaxy.Weekly" (port 80, ssl 443, ID=1272369728) that is working fine. I have an entry in windows/system32/drivers/etc/hosts that links galaxy.Weekly.scjdev.ds to the server ip in both my local machine and in the application Server. These sites works: http://scj.galaxy.weekly/test.html works http://scj.galaxy.weekly/test.aspx works But https://scj.galaxy.weekly/test.html fails Error message is: The connection was reset The connection to the server was reset while the page was loading. The certificate was working fine for months. It was created with something similar to this: Selfssl /N:CN=*.scjdev.ds /V:3650 /S:1 /P:443 I have tried several options and none of them are working: 1) Create a certificate only in "Default Web Site" and link it to SecureBindings with command prompt cscript adsutil.vbs set /w3svc/1272369728/SecureBindings ":443:galaxy.Weekly.scjdev.ds" 2) Create a certificate only in "Galaxy Site" and link it to SecureBindings 3) Create a certificate in both and link them to secureBindings. Probably I am missing an step or something, but I can't see it. Here is the relevant config of Galaxy Site: <IIsWebServer Location ="/LM/W3SVC/1272369729" AuthFlags="0" LogPluginClsid="{FF160663-DE82-11CF-BC0A-00AA006111E0}" SSLCertHash="c36a514a0be90fbc121d9c19bb052842289d5aee" SSLStoreName="MY" SecureBindings=":443:galaxy.Weekly.scjdev.ds" ServerAutoStart="TRUE" ServerBindings=":80:galaxy.Weekly.scjdev.ds" ServerComment="galaxy.Weekly.scjdev.ds" > </IIsWebServer> <IIsWebVirtualDir Location ="/LM/W3SVC/1272369729/root" AccessFlags="AccessRead | AccessScript" AppFriendlyName="Default Application" AppIsolated="2" AppRoot="/LM/W3SVC/1272369729/Root" AuthFlags="AuthAnonymous | AuthNTLM" DefaultDoc="Default.aspx" DirBrowseFlags="EnableDirBrowsing | DirBrowseShowDate | DirBrowseShowTime | DirBrowseShowSize | DirBrowseShowExtension | DirBrowseShowLongDate" Path="D:\Webs\Galaxysite" ScriptMaps="some config...

  • Should the MAC Tables on a switch Stack be the same between sessions?

    - by Kyle Brandt
    According to Cisco's documentation: "The MAC address tables on all stack members are synchronized. At any given time, each stack member has the same copy of the address tables for each VLAN." However, when logged into the switch I see the following: ny-swstack01#show mac ad | inc Total Total Mac Addresses for this criterion: 222 ny-swstack01#ses 2 ny-swstack01-2#show mac ad | inc Total Total Mac Addresses for this criterion: 229 ny-swstack01-2#exit ny-swstack01#ses 3 ny-swstack01-3#show mac ad | inc Total Total Mac Addresses for this criterion: 229 ny-swstack01-3#exit ny-swstack01#ses 4 ny-swstack01-4#show mac ad | inc Total Total Mac Addresses for this criterion: 235 ny-swstack01-4#exit ny-swstack01#show mac ad | inc Total Total Mac Addresses for this criterion: 222 Going back and forth this isn't just because it is changing over time either, within certain sessions there are entries that I don't seen from the master session. We are currently waiting to hear back on CIsco from this, but has anyone run into this before? I stumbled upon this when looking into Unicast flooding, one of the hosts that is a destination MAC of flooding has a MAC entry that appears in session 3, but nowhere else. Also, I checked an all sessions show the same aging time.

  • Odd one: IE6 showing the "view source" command enabled when I was expecting it to be disabled.

    - by caerphilly
    Hi, OK, I admit this problem is odd. I'm just trying to understand why IE is behaving the way it is. I realise that logic may not apply here :) I have Internet Explorer 6 (Sp1) running on Windows 2000. The IE option "Do not store encrypted pages to disk" is checked (enabled). The temporary internet files folder is empty. TEMP and TMP environment variables are set to valid folders. I'm connected to a web server over SSL. The web server is serving a page over SSL with the HTTP cache-control header set to "no-cache, no-store". I was expecting the "view source" command to be greyed out in this circumstance (as it is on another machine). But it works. When I "view source", I get an entry in the Temporary Internet Files folder with an "internet address" property of "view-source:https://myserver/...." and the content of the page. I wasn't expecting that. I can't understand why one machine is different to another in this regard. Obviously there is some environment/setup difference, but I can't track it down. Anyone have any bright ideas?

    Hi, This is my first post on serverFault and my first entry in to web server configuration. The hardware and software. CPU: GenuineIntel, Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz OS: Linux 2.6.18-128.el5 Memory: 2Gb Background. I am running a small database (MySQL), around 1000 records with each record containing 44 fields. At the start of each day “00:01” the tables are cleared and populated with fresh data. The are 10 remote PCs all running Winodws XP and Firefox internet browser. All remote PC’s are connected to the internet using a min 4Gb broadband connection. Each remote PC runs a URL which displays a dynamic page of data which is refreshed every 20 seconds. This is a continual process 24 hours a day. I problem I am having is on odd occasions throughout the day the PC browser error with “Server taking too long to respond error”. What I am trying to find our is if I have the correct setting in the httpd.conf file on the server. Any help or advice anyone can provide would be very helpful.

  • How to prevent the command prompt from closing after execution?

    - by Sk8erPeter
    My problem is that in Windows, there are command line windows that close immediately after execution. To solve this, I want the default behavior to be that the window is kept open. Normally, this behavior can be avoided with three methods that come to my mind: Putting a pause line after batch programs to prompt the user to press a key before exiting Running these batch files or other command line manipulating tools (even service starting, restarting, etc. with net start xy or anything similar) within cmd.exe(Start - Run - cmd.exe) Running these programs with cmd /k like this: cmd /k myprogram.bat But there are some other cases in which the user: Runs the program the first time and doesn't know that the given program will run in Command Prompt (Windows Command Processor) e.g. when running a shortcut from Start menu (or from somewhere else), OR Finds it a little bit uncomfortable to run cmd.exe all the time and doesn't have the time/opportunity to rewrite the code of these commands everywhere to put a pause after them or avoid exiting explicitly. I've read an article about changing default behavior of cmd.exe when opening it explicitly, with creating an AutoRun entry and manipulating its content in these locations: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor\AutoRun HKEY_CURRENT_USER\SOFTWARE\Microsoft\Command Processor\AutoRun (The AutoRun items are _String values_...) I put cmd /d /k as a value of it to give it a try, but this didn't change the behaviour of the stuffs mentioned above at all... It just changed the behaviour of the command line window when opening it explicitly (Start-Run-cmd.exe). So how does it work? Can you give me any ideas to solve this problem?

  • Static DHCP binding

    - by Alex
    Good time of day, SF people. I have created a manual DHCP binding entry on a Cisco router so that a client would always get leased to it. The clients wants to get the same address on both of his dual-boot linux systems. He tries to get an IP address leased and he succeeds on one of the dual-boot operating systems. When he reboots to another one he gets a lease for a completely different one. I don't get it. The MAC addresses are the same (we checked in ifconfig, so what could be happening here? Why is the router confused? Or is it something else? Also, how can I check DHCP server IP address who I have got an IP address from (on Linux)? Configuration on Cisco: ip dhcp pool MANUAL_BINDING0001 host 192.168.0.64 255.255.255.0 hardware-address dead.beef.1337 dns-server 192.168.8.11 default-router 192.168.0.254 domain-name verynicedomainigothere.cn PS. Is it mandatory to use client-name configuration line?

  • Identifying test machines in analytics logs

    - by RTigger
    We're just beginning to add analytics to our SaaS application, to begin (among other things) billing clients based on usage. The problem we're running into is there's a few circumstances where our support team will simulate a log in into production to try to reproduce reported issues with a client's configuration. When they log in, an entry will be made into our analytics logs that their specific account has logged in, which we use to calculate billing. A few ideas we had to solve this: 1) We log IP addresses as well as machine keys for each PC that logs in - we could filter out known IP addresses and/or machine keys belonging to support. The drawback is we have to maintain a list of keys / addresses manually. 2) If support (or anyone else internal) runs our application in debug mode (as opposed to release), it will not report analytics. This is fine, as long as support / anyone else remembers to switch to debug mode. 3) Include some sort of reg key / similar setting required to be set when configuring a production system in order to send analytics. Again, fine, as long as our infrastructure team remembers to set the reg key or setting. All of these approaches require some sort of human involvement, which we all know can be iffy at best. Has anyone run into a similar situation? Is there an automated approach to this problem? (PS Of course, we shouldn't be testing in production, but there are a few one-off instances with customer set up that we can't reproduce without logging in as them in production. This is the only time we do so, and this is the case I'm talking about in this question.)

  • Gnome 3 application Icons disappeared

    - by robin.koch
    I edited my main menu settings (unchecked items inside a sub menu) when it happened that the window freezed and all entries on the left side disappeared (Office, System, Settings, Games, ...). I didn't think much about it, but when I restarted my computer all application entries in my menu and my favorites (quickstart bar on the left side) where gone. When I go to activities - applications I just see the "All" entry without any items to click on. ~/.config/menu/gnome-applications.menu is an empty file and ~/.config/menu/gnome-settings.menu has the folowing content: <!DOCTYPE Menu PUBLIC '-//freedesktop//DTD Menu 1.0//EN' 'http://standards.freedesktop.org/menu-spec/menu-1.0.dtd'> <Menu> <Name>Desktop</Name> <MergeFile type="parent">/etc/xdg/menus/gnome-settings.menu</MergeFile> </Menu> I also looked into the files under /etc/xdg/menus. They look like template files without any reference to actual installed programs. I assume that due to a bug it deleted all my menu settings. Is there any way to restore at least the default menu? Or are there any other places to look for my old configuration?

  • Which free RDBMS is best for small in-house development?

    - by Nic Waller
    I am the sole sysadmin for a small firm of about 50 people, and I have been asked to develop an in-house application for tracking job completion and providing reports based on that data. I'm planning on building it as a web application. I have roughly equal experience developing for MySQL, PostgreSQL, and MSSQL. We are primarily a Windows-based shop, but I'm fairly comfortable with both Windows and Linux system administration. These are my two biggest concerns: Ease of managability. I don't expect to be maintaining this database forever. For the sake of the person that eventually has to take over for me, which database has the lowest barrier to entry? Data integrity. This means transaction-safe, robust storage, and easy backup/recovery. Even better if the database can be easily replicated. There is not a lot of budget for this project, so I am restricted to working with one of the free database systems mentioned above. What would you choose?

  • Windows 7: moved system partition, need to update boot partition

    - by Actorclavilis
    So, I have a decently standard Windows7/Ubuntu dual-boot setup, and (since Ubuntu is my usual operating system) I found I needed to grow my Ubuntu partition and shrink my W7 partition. Originally, my system (500G) looked like this: W7 Boot Partition (1.5G) Ubuntu (around 240G) W7 (same as Ubuntu) (on an extended partition, all by itself) Swap (rest of disk, around 16G) Now I'm no stranger to partitioning and filesystem tools, especially GParted, which I used on a Linux boot disk. After my partition editing, the partitions are laid out the same, except the Ubuntu partition is now 407G and the W7 partition is smaller to compensate. I had supposed, based on http://www.gparted.org/faq.php, that I would be able to run the W7 install disk in recovery mode and have it deal with the rearrangement, then possibly reinstall GRUB or something. Well, now the W7 install disk doesn't even see my W7 installation. All my files are there, the NTFS is perfectly clean, no problems there, but the install disk won't notice it. (Of course, the GRUB entry works fine but the W7 boot partition (which I didn't change) refuses to boot it.) So, basically, any ideas on how to fix this? I don't especially want to rerun the entire install procedure because I'll have a bunch of programs to reinstall (never mind redoing GRUB), but I fear that might be the only option. Thanks.

  • Windows Vista Context Menu>New... does not find entries

    - by Paul
    I was trying to remove a virus and foolishly did not backup registry keys I deleted because I (thought) I only deleted entries from the folders of programs I did not care about. However, I think I have done something wrong here: Now when I open a context menu (right click) in any location and hover over the "New..." option I don't get any options. It has a greyed out box saying "(Empty)". So far I have found out the the entries themselves are still there (using the locations provided here: Windows 7 - Add an item to 'new' context menu). I have also used a program recommended in that thread which also finds the entries intact and enabled. So it seems maybe I have deleted the entry which tells Vista where to look to find the files that can be created. How can I restore this so entries are shown again? I know system restore is an option but as I have said I did this when removing a (very stubborn) virus so that is the last resort.

  • Windows 7 system freezes: would like to know if they could be related to MrxSmb, Event ID 8003 errors

    - by lifegoeson
    First, this question centers around a home network. Is it okay to ask here? Or should I go to SuperUser? (I see less answers over there, but I'll go there if that would be more appropriate.) Network setup: 1 Machine running XP Pro 1 Machine running Win7 Ultimate Comcast router Linksys WRT610N Wireless router The Win7 machine goes into a total, unrecoverable system freeze frequently. I was tearing out my hair trying to ascertain a cause, but I noticed that it usually seems to correspond with performing operations on the shared folders on the XP machine. The last 2 occasions that the Win7 machine froze, I saw this entry for Event ID 8003 from source MrxSmb in the Event log of the XP machine: The master browser has received a server announcement from the computer WIN7_COMPUTER that believes that it is the master browser for the domain on transport NetBT_Tcpip_{320B32A7-FED9. The master browser is stopping or an election is being forced. My question is twofold: Could this cause a Win7 system freeze? If so, what could I configure differently on my network to stop these conflicts over who is the master browser? Thank you for your help!

  • Faster caching method

    - by pataroulis
    I have a service that provides HTML code which at some point it is not updated anymore. The code is always generated dynamically from a database with 10 million entries so each HTML code page rendering searches there for say 60 or 70 of those entries and then renders the page. So, for those expired pages, I want to use a caching system which will be VERY simple (like just enter a record with the rendered HTML and (if I need) remove it). I tried to do it file-based but the search for the existence of a file and then passing it through php to actually render it , seems like too much for what I want to do. I was thinking of doing it on mysql with a table with MEDIUMBLOBs (each page is around 100k). It would hold about 150000 such records (for now, at least). My question is: Would it be faster to let mysql do the lookup of the file and the passing to php or is the file-based approach faster? The lookup code for the file based version looks like this: $page = @file_get_contents(getCacheFilename($pageId)); if($page!=NULL) { echo $page; } else { renderAndCachePage($pageId); } which does one lookup whether it finds the file or not. The mysql table would just have an ID (the page id) and the blob entry. The disk of the system is a simple SATA raid 1 , the mysql daemon can grab up to 2.5GB of memory (i have a proxy running too, eating the rest of the 16GB of the machine. ) In general the disk is quite busy already. My not using PEAR cache, is because I think (please feel free to correct me on this) it adds overhead I do not need because the page rendering code is called about 2M times per day and I wouldn't want to go through the whole code each time (and yes, I have eaccelerator to cache the code too). Any pointer to what direction I should go, would be greatly welcome. Thanks!

  • How to chain GRUB2 for Ubuntu 10.04 from Truecrypt & its bootloader (multi boot alongside Windows XP partition)?

    - by Rob
    I want Truecrypt to ask for password for Windows XP as usual but with the standard [ESC] option, on selecting that, i.e via Escape key, I want it to find the grub for the (unencrypted) Ubuntu install. I've installed Windows XP on the 120Gb hard drive of a Toshiba NB100 netbook then partitioned to make room for Ubuntu 10.04 and installed that after the Windows XP install. When I encrypt Windows XP, Truecrypt will overwrite the grub entry in the master boot record (MBR), I believe (?) and I won't be able to choose between XP and Ubuntu anymore. So I need to restore it back. I've searched fairly extensively for answers on Ubuntu forums and elsewhere but have not yet found a complete answer that covers all eventualities, scenarios and error messages, or otherwise they talk of legacy GRUB and not GRUB2. Ubuntu 10.04 uses GRUB2. My setup: Partitions: Windows XP, NTFS (to be encrypted with Truecrypt), 40Gb /boot (Ext4, 1Gb) Ubuntu swap, 4Gb Ubuntu / (root) - main filesystem (20gb) NTFS share, 55Gb I know that the Truecrypt boot loader replaces the GRUB when boot up because I've already tried it on another laptop. I want boot loader screen to look something like the usual: Truecrypt Enter password: (or [ESC] to skip) password is for WindowsXP and on pressing [ESC] for it to find the Ubuntu grub to boot from Thanks in advance for your help. The key area of the problem is how to instruct Truecrypt when escape key is pressed, and how the Grub/Ubuntu can be made visible to the truecrypt bootloader to find it, when the esc key is pressed. Also knowing as chaining.

  • Mail server DNS failed to resolved by Mac clients

    - by Concordus Applications
    We have two internal DNS servers. One is located on a linux server box and the other is the router's DNS management. We set the linux box as primary DNS via DHCP and the router as secondary. We have a few Mac clients that are accessing our internal mail server (hostnamed "mail" internally). When using IMAP or SMTP against the mail server internally, the mac boxes will sometimes fail to locate the server. If I use NSLOOKUP I can see that "mail" is pointed to the correct IP address and is being resolved via the correct DNS server, but if I ping "mail" it fails. ~ (bash)$ nslookup mail Server: 254.254.254.206 Address: 254.254.254.206#53 Name: mail.example.com Address: 254.254.254.205 Note: I replaced our actual internal IP address with 254.254.254.* If I wait a few minutes (3-5 minutes), somehow it resolves itself and sends successfully. This happens multiple times a day. The /etc/hosts file on the mac boxes is the default config. ## # Host Database # # localhost is used to configure the loopback interface # when the system is booting. Do not change this entry. ## 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost Is there something about Mac clients I should know to prevent this failed DNS resolution? Client boxes are: OSX 10.7.4, 8GB RAM, i5 MacBooks Server is: Ubuntu 12.04 Server

  • Multi-petabyte scale out storage solution [closed]

    - by Alex Yuriev
    Let's say that I have a need to have a single-name space scale to multi-petabyte object store with a file system-like wrapper. What is currently out there that supports the following: Single name space that can take 1B files. Support for multiple entry points using NFS At least node level replication ( preferably node and file level replication ) Online software upgrades No "magic sauce" on the storage layer The following has been evaluated: Gluster & Lustre - just ick - fundamental lack of understanding of why online upgrades are mandatory. OneFS - we have it. It is smelling more and more like it hides a dead body under the hood. Other than MapR and zfs am I missing anything? P.S. Oh yes, I keep forgetting that the forums are for people to discuss if 2TB drive actually stores 2TB info. May bad. Seriously though - how the heck can "meets the following requirements" can be considered a "debate"? P.P.S. I did not throw an idiotic insult - i pointed out that this is actually an interesting question compared to a conversation about storage capacity of a 2TB hard drive. It is not a question of what works better - it is a question that asks did I miss any of the products that currently exist which fit the criteria where criteria is clearly outline. I got one answer below which included something that I have not looked at in a long time which looks quite a bit grown up compared to the time I briefly look at it before.
