  • g++ in Knoppix 6 LiveCD

    - by HazyBlueDot
    To avoid the inevitable, let me put this in context. I am instructing an Intro to Unix course this semester and the students are using Knoppix 6.4.3 off the LiveCD. They are not required to install the system to their hard drive, and I would like to not require them to, however they do have use of a USB flash drive. This version of Knoppix seems to include gcc, but NOT g++. The course curriculum requires compiling C++ programs. I know I can run: sudo apt-get update sudo apt-get install build-essential to install (among other things) g++, but of course this only makes sense on a system installed to a hard drive. So my question is, can I write a script that calls gcc with appropriate options and flags to compile a C++ program that students could use in place of g++?

  • Is it possible to install Windows 8 on the SanDisk ReadyCache 32GB SSD drive?

    - by halil ibrahim
    I bought the SanDisk ReadyCache 32GB SSD drive this week. I didn't know about the caching stuff and thought that I would be able to install Windows 8 on it. Now I'm using it as a cache drive with the ExpressCache software. But I wonder if it is possible to use this SSD as a primary system drive with an operating system installed on it. I've tried to format the disk via Windows Disc Manager Tool, but the format option is disabled. Only delete and information options are allowed. Can you help me with this?

  • Flash not Working in Google Chrome for Mac

    - by Blakeasd
    Flash has randomly stopped working in Google Chrome for Mac. All that appears is a white flash then nothing. I can hear sound, and when I right click on where Flash is supposed to be I see the Flash Player options. I have completely reinstalled Chrome, including deleting all of its support files. I reinstalled my system flash and tried making Chrome use my system flash, but nothing works. Flash is fine in Safari, but not in Chrome. How do I fix this? I am running the latest Google Chrome Dev build (21.0.1171.0) and Mac OS X 10.7.4 . Thanks!

  • Mother Board Question

    - by user33931
    1st, I am software guy. I do not do hardware. So I know to you hardware geeks, this is a dumb question. I just inherited a box with a ASUS P5GZ-MX mother board. I have attempted to install two nVidia PCI video cards. I put a 750w power supply in the system to be sure I have enough power. With no extra video cards, the 3.3 v shows normal. When I put one card in, the 3.3 goes to 3.5-3.6 and flashes red (over voltage) about 30% of the time. When I put the 2nd card in, it goes to 3.73 v and stays red all the time. Any Ideas why the voltage goes up when I add cards instead of going down? More Importantly, is this dangerous to the system?

  • How best to backup 6x Win2k3 Servers

    - by saille
    We have a external HP LTO3 tape drive. It needs to backup 6 Windows 2003 machines every night. Servers are HP DL380 G3 and the tape drive is attached locally to one of them via SCSI. On a budget of $0, and a goal of keeping-it-simple, what is going to be the best way to backup these machines? What software to use? NT Backup? Or does HP have something better for free? We don't need image backups - file system + system state will be adequate. Do we need to copy the files to be backed up onto the machine with the tape drive attached? Edit: Let me ask a more focussed question: Would you use NT Backup or something else? No soap boxing please, we've after some quick advice from someone who's used a similar setup.

  • Making Sure Which Partition to Choose with Linux Dual Boot?

    - by user128360
    In the Linux Mint 12 LXDE the partitions are listed as nsd 1, 2, 3, 4, though I have a Windows 8 CP installation on one of the two partitions on the single hard drive. The space usage is differing in both system calculations, though still relateable. Where the partition is at around 20 GB usage in Windows 8 it will be at around 24 GB in the Linux installation menu. I am just wondering is there a certain way to choose the right partition? Also in the drop down menu regarding the boot loader, there are multiple options, which one would be the one to be chosen in this case? What about the system-reserve partition of Windows 7 (the one I am trying to overwrite)? What is happening with that?

  • HD movies stutter.

    - by Absolute0
    I just put together a new system build in the hopes that all of my daily tasks would run smoothly and without any hiccups. Unfortunately I am still seeing some sound and sometimes video stuttering when playing HD movies in VLC (no problems with xvid/divx files). My setup is as follows: Intel core i5 750 quad core 2.66mhz 4GB ram asus p55 motherboard radeon hd 5570 video card 650gb 7200rpm western digital sata HDD 23" Nec ea23wmi monitor Operating System: Windows 7 What might be the main bottleneck that needs upgrading to fix my delays? Seems like the hard drive might be the problem but anything faster than 7200rpm is beyond my budget for a decent hard drive. Could it be anything else?

  • How would I / could I obtain an reasonably comprehensive list of domain names?

    - by Simon
    I know that domain names are constantly changing, and I know there are a lot of them, but there is clearly a region of the domain name space which is stable. How would I go about getting a list, even a very big one? Such a thing must logically exist, even if it is in a distributed form, because the web's DNS servers resolve names to IP addresses. So in theory if I could poll all the DNS servers in the world at a moment in time I would have the complete list of mapped names. Is there a practical way of doing that? As an aside, does anyone have any good estimates of how many domain names exist at the moment?

  • How to install windows 7 from scratch on a disk which already contains partitions

    - by rangalo
    Hi, I have following partitions on a 1 TB disk. 14 GB UNKNOWN recovery partition 100MB NTFS System Reserved partition for Windows 7 448GB NTFS Windows 7 system partition 468GB NTFS Data partition for windows 7 Now because of the problems mentioned in my other question here I got a brand new windows 7 cd and want to install it from scratch after deleting all the extra partitions. But windows 7 installation doesn't give me such options. It refuses to touch the 14GB Recovery and 100 MB (reserved by previous windows 7) partition. Any ideas ? Note: Because of it is a dynamic disks most of the freely available tools refuse to delete the partitions on the disk. regards.

  • Internet cafe software for linux

    - by pehrs
    I have gotten a request to roll out a total of 8 internet cafe's in a large network. Budget is non-existent as it will all be done for a non-profit. I was planing to use Ubuntu and live-cds to minimize the amount of management required, but I can't seem to find any suitable internet cafe system that is Ubuntu based. The requirements are pretty basic: It needs to keep track of logged in time and log out users when their time it up. No billing will be done, it will just be used to ensure people can share the computers fairly. It should be possible to force logout from a central system. Users will be unskilled, so it has to have a GUI. What (preferably free, considering the shoe-string budget) software would you suggest to manage this?

  • baffling stat pauses - (reiserfs)

    - by Twirrim
    I've got a SuSE server with reiserfs formatted partitions, all on a RAID1 mirror. I'm noticing odd spikes in iowait, but generally all seems okay. iostat claims not even 3% iowait in general: avg-cpu: %user %nice %system %iowait %steal %idle 6.53 0.03 1.45 2.92 0.00 89.07 After tracking down some odd behaviour when ls'ing, it appears "stat" (ls is aliased to include color which does a stat process on each file) randomly takes 5 seconds on a file in the directory. ReiserFS does a file system sync every 5 seconds, but that's interval between not length of time taken to sync. Out of curiosity I did remount using noatime to see if that would help though as it would reduce sync's workload, but no joy. Anyone got any thoughts what might be causing this pause? Disks appear healthy, RAID controller believes the RAID is healthy, and io stats show the disks aren't working very hard at all.

  • Understanding the Linux Root

    - by Zac
    I've been using Linux (Ubuntu) for about 2 weeks now and am still struggling with some basic concept surrounding the root user: (1) Some terminal operations (such as making subdirectories inside a FHS directory such as /opt) require me to prefix the command with sudo - why? I guess what I'm choking on is: if I'm already logged in as a valid system user, why do I have to be a superuser/root in order to modify things that the sysadmin has already deemed me worthy of accessing? (2) Is there a GUI (Gnome, KDE) equivalent to sudo? Is there a way to assume a superuser role through a graphical context, rather than from inside a new shell? (3) I can't access the /root directory logged in as myself... but I installed the system to begin with and was never asked to create a root account! How do I log in as root and gain access to /root?!? Thanks for all feedback & input!

  • FoxPro 2.6 DOS on Windows 7 64-bit

    - by Rolando
    I support a company that has a very old, mission critical, FoxPro for DOS 2.6 (FPD) application. For variuos reasons the company didn't adapt/migrate their app, which, ironically, has been running even better under Windows XP (and 32-bit Win7) because the OS allowed new features like more reliable networking, distributed printing, email integration. Unfortunately for this company, most new machines now come with a 64-bit version of Windows 7, which is incompatible with their FPD app. I know this time the writing is on the wall: the only long-term solution is to migrate their app. But I wonder if anyone can suggest a temporary alternative path, which doesn't involve either: a) downgrade 64-bit Windows to 32-bit, or b) run the app on a virtualized 32-bit XP Thanks! PS: Happy New Year!!!

  • FoxPro 2.6 DOS on Windows 7 64-bit

    I support a company that has a very old, mission critical, FoxPro for DOS 2.6 (FPD) application.

  • Where is custom icon information stored in Mac OS X Snow Leopard?

    - by AmazingRobie
    I have an external Lacie hard drive connected via USB to my Macbook Pro which is running Snow Leopard. I have nothing but music on the external drive with every album sorted in it's own individual folder and have changed all of the individual folder icons to display the album art of the songs from the album inside. I want to reformat my laptop, but I'm afraid if I do that, the album art will disappear if it's stored on a system file within the main hard drive OS. My question is this, is the information which tells the OS to display the album art listed in a hidden system file on the external Lacie drive or my laptop hard drive and if I reformat will I have to reassociate all of the album art to the folders on the external or will it keep it's associations. Thanks in advance.

  • How can I sign my server with an SSL certificate

    - by Saif Bechan
    I have a dedicated server and I want to use one domain name for default entrance to the system. My system is Apache 2 on CentOS 5.4. Lets says the domain name is mydomain.com. I have also bought an SSL certificate and installed it to work with this default domain. Still when I restart Apache I get the following error message: [Sat May 01 02:21:22 2010] [warn] RSA server certificate is a CA certificate (BasicConstraints: CA == TRUE !?) [Sat May 01 02:21:22 2010] [warn] RSA server certificate CommonName (CN) `mydomain.com' does NOT match server name!? Does anyone have an idea how I can remove this message. I have the server, domain name, and ssl key.

  • Why does Windows spooler require an administrator account?

    - by Software Monkey
    Does anyone know what changes I might need to make to allow restricted users to print using a printer configured for spooling? My Windows XP SP3 system currently requires me to use an Admin account for printing if the printer is configured to spool documents before printing. If the printer is configured for direct printing it works for all accounts. This used to work and some months back it just stopped, and I can't pin down why. The printer, which is an HP PSC 1200 (an old printer) itself is configured for Everyone to have Print authority and my specific (restricted) account to have Full authority, that is Print, Manage Printers and Manager Documents. My HDD is locked down for restricted users given them only read authority to the entire file system except their data directories, which is how I have run my systems for years. I assume there may be a directory somewhere that I need to allow users to write to.

  • HP MSR 30-10a Router - Route Traffic over Default Route

    - by SteadH
    We have a brand new HP MSR 30-10a Router. We have a fairly simple routing situation - we have two IP blocks, one which has a route out. We need things on the first block to go through the router, and out. I have an old Cisco 2801 router doing the job right now. For our example - IP Block 1: 50.203.110.232/29, Router interface on this block is 50.203.110.237, route out is 50.203.110.233. IP Block 2: 50.202.219.1/27, Router interface on this block at 50.202.219.20. I have a static route created for: 0.0.0.0 0.0.0.0 50.203.110.233 The router seems to understand this. When on the CLI via serial cable, I can ping 8.8.8.8 and hear responses from Google DNS. Woo hoo! The issue arrives when any client sits on the IP Block 2 side. I configured my client with a static IP of 50.202.219.15/27, default gateway 50.202.219.20. I can ping myself. I can ping the near side of the router (50.202.219.20), and I can ping the far side of the router (50.203.110.237. I cannot ping anything else in IP block 1, nor can I ping 8.8.8.8. Here is my configuration file: <HP>display current-configuration # version 5.20.106, Release 2507, Standard # sysname HP # domain default enable system # dar p2p signature-file flash:/p2p_default.mtd # port-security enable # undo ip http enable # password-recovery enable # vlan 1 # domain system access-limit disable state active idle-cut disable self-service-url disable # user-group system group-attribute allow-guest # local-user admin password cipher $c$3$40gC1cxf/wIJNa1ufFPJsjKAof+QP5aV authorization-attribute level 3 service-type telnet # cwmp undo cwmp enable # interface Aux0 async mode flow link-protocol ppp # interface Cellular0/0 async mode protocol link-protocol ppp # interface Ethernet0/0 port link-mode route ip address 50.203.110.237 255.255.255.248 # interface Ethernet0/1 port link-mode route ip address 50.202.219.20 255.255.255.224 # interface NULL0 # ip route-static 0.0.0.0 0.0.0.0 50.203.110.233 permanent # load xml-configuration # load tr069-configuration # user-interface tty 12 user-interface aux 0 user-interface vty 0 4 authentication-mode scheme # My guess right now is there is some sort of "permission" needed to use the default route. The manuals haven't turned up a lot in this area that don't make the situation much more complicated (but maybe it needs to be more complicated?) Background: we use HP switches, and I love the CLI. I bought HP thinking the command line interface would be similar, or at least speak the same language. Whoops! I'd be happy to provide more information or perform any additional tests. Thanks in advance! Update 1: The manual mentions routing rules. I hadn't previously added these (since our Cisco 2801 seems to route anything by default). I added: ip ip-prefix 1 permit 0.0.0.0 0 less-equal 32 alas, still no dice.

  • In Jetty, can NCSARequestLog be configured to auto-detect the time zone?

    - by David Moles
    It looks as though in 2003 or so NCSARequestLog would pick up the system time zone using TimeZone.getDefault().getID(), but in more recent versions it seems as though it's hard-coded to GMT, unless you override it in jetty.xml or programmatically. If true, this kind of annoying, since it means if you don't want GMT logging you have to edit jetty.xml for every installation (not to mention twice a year for daylight saving time). Is there a workaround that will let Jetty pick the time zone up from the system? (X-posted to Stack Overflow.)

  • My computer keeps crashing and I just want it FIXED

    - by xabaddon
    So long story short, I had my brother build me a computer for my birthday last year. I saw how good his was (also built by him) so I decided I would have him build me one. About a month after this was all finished, my computer started crashing when I when run over 3 programs. For example, an online game, a music player (spotify), skype, and a browser with a few tabs open. The way it would crash is the screen will freeze and a buzzing noise will come from whatever audio device I am using (headset, speakers) I took it to a computer tech guy and he told me my cooling system was inadequate. SOOO he led me to buy a CORSAIR H75 Liquid cooling system. Everything was good for about a week, and now it just did the same thing again. I am so freaking over this guys and I really need some help figuring out what the heck is wrong, I dont care how long it takes, just please help me.

  • Win 8: Adding a boot volume to an MBR dynamic disk [NOT about changing to basic disks]

    - by Stilez
    (This is NOT aiming to convert to basic disk. In this question, the disk stays dynamic but becomes bootable) There doesn't seem to be a clear, well stated answer I can find, for the question "What are the criteria for Windows 8 to successfully boot from an MBR dynamic disk", or "how do I fix a dynamic MBR partition that's failing boot"? I've tried to educate myself but can't find crucial information to clear it all up. My existing HDD/SSD setup: DISK 0 ~ 60GB SSD/MBR/basic: (350MB recovery)(60GB windows 8 bootable) DISK 1 ~ 512GB SSD/MBR/dynamic: (350MB recovery)(60GB unallocated)(410GB mirrored data) DISK 2 ~ 512GB SSD/MBR/dynamic: (350MB recovery)(60GB unallocated)(410GB mirrored data) DISKS 3, 4, 5: (ignored for simplicity: 2xHDD RAID1 + caching SSD) I'm heavy duty on data crunching and virtualisation, just maxxed out 32GB RAM @ 2133 and moved to 4960X + 64GB. Disk 0 is a pure system disk of little value, and virtualisations runs off mirrored SSDs (Samsung 840 Pro 512 x 2) for double speed reading and so they snapshot in reasonable time. I'm using 4 SATA3 ports and the board only has two decent Intel ports (onboard Marvell are poorer quality). I'm wary of choosing between LSI, HighPoint and other 3rd party controllers as I'm unfamiliar with the maze of decent RAID cards (that's a whole other issue!). I want to cut down my SSD needs by moving the boot volume and caching volume to the 840 pros, giving a setup with 2 fewer SSDs: DISK 0 ~ 512GB SSD/MBR/dynamic: (350MB recovery)(60GB boot)(410GB mirrored data) DISK 1 ~ 512GB SSD/MBR/dynamic: (350MB recovery)(30GB cache for the ICH10R mirror)(30GB temp)(410GB mirrored data) DISKS 2, 3: (2xHDD RAID1) Intel's RST allows this, Win 8 allows booting off a MBR/dynamic disk, and the two 60GB SSDs are hardly the fastest SSDs anyway, they'll get repurposed. Moving the caching volume is easy. Moving the boot volume has me stumped. The difficulty is, I'm hitting a wall of knowledge here. I have a UEFI Asus motherboard with an previous traditional MBR/basic boot disk, and I want it to boot from a disk and volume that's MBR/dynamic. The disk copy is physically ok (Partition Wizard Server will copy to dynamic volumes) but then hits a light blue 0xc000000e boot error. No real surprise, I expected to have some boot fixing, but had expected Windows to boot-fix it (all drivers exist), or the usual manual fixes to work. Specifically, I don't know enough, to know what's got to be manually checked and perhaps corrected for the disk to boot (legacy/uefi/bios, odd partitions, boot tables, disk IDs, hidden boot files, oh my!), or if I need to change any of this secure boot/UEFI/legacy stuff in the bios, convert a 512 SSD to basic and then back to dynamic when working, or if the issue is pure OS config using "diskpart", "bootsect" and "bootrec" from the Win8 DVD. The old system disk still boots but I don't know enough to figure what to fix, to make the system boot as I want. The answers probably aren't hard but the real issue is my confusion and missing information. Thanks for helping!

  • How to make Shared Keys .ssh/authorized_keys and sudo work together?

    - by farinspace
    I've setup the .ssh/authorized_keys and am able to login with the new "user" using the pub/private key ... I have also added "user" to the sudoers list ... the problem I have now is when I try to execute a sudo command, something simple like: $ sudo cd /root it will prompt me for my password, which I enter, but it doesn't work (I am using the private key password I set) Also, ive disabled the users password using $ passwd -l user What am I missing? Somewhere my initial remarks are being misunderstood ... I am trying to harden my system ... the ultimate goal is to use pub/private keys to do logins versus simple password authentication. I've figured out how to set all that up via the authorized_keys file. Additionally I will ultimately prevent server logins through the root account. But before I do that I need sudo to work for a second user (the user which I will be login into the system with all the time). For this second user I want to prevent regular password logins and force only pub/private key logins, if I don't lock the user via" passwd -l user ... then if i dont use a key, i can still get into the server with a regular password. But more importantly I need to get sudo to work with a pub/private key setup with a user whos had his/her password disabled. Edit: Ok I think I've got it (the solution): 1) I've adjusted /etc/ssh/sshd_config and set PasswordAuthentication no This will prevent ssh password logins (be sure to have a working public/private key setup prior to doing this 2) I've adjusted the sudoers list visudo and added root ALL=(ALL) ALL dimas ALL=(ALL) NOPASSWD: ALL 3) root is the only user account that will have a password, I am testing with two user accounts "dimas" and "sherry" which do not have a password set (passwords are blank, passwd -d user) The above essentially prevents everyone from logging into the system with passwords (a public/private key must be setup). Additionally users in the sudoers list have admin abilities. They can also su to different accounts. So basically "dimas" can sudo su sherry, however "dimas can NOT do su sherry. Similarly any user NOT in the sudoers list can NOT do su user or sudo su user. NOTE The above works but is considered poor security. Any script that is able to access code as the "dimas" or "sherry" users will be able to execute sudo to gain root access. A bug in ssh that allows remote users to log in despite the settings, a remote code execution in something like firefox, or any other flaw that allows unwanted code to run as the user will now be able to run as root. Sudo should always require a password or you may as well log in as root instead of some other user.
