• How to Program AWS Spot Instances to Strategically Bid So the Auction is Never Lost Until a Competitor Beats the Maximum I'm Willing to Pay?

  - by Taal

  I believe I'm in the right section of stack exchange to ask this. If not, let me know. I only use Amazon Web Services for temporary type hosting services, so the spot instances are quite valuable to me. I would also just make an instance and start and stop it - but - that doesn't necessarily fit my bootstrapped budget sadly. Anyways, it really kills me when someone outbids me on a spot instance I have (I tend to go for the larger ones which there are fewer of available) and I get randomly kicked off. I know or at least I believe there is a way to program in something somehow to dynamically change your bidding price to beat a potential competitor's if their's is higher than yours. Now, I previously believed Amazon would just charge me for the highest price right above the next lowest competitor automatically (eliminating the need for this) - so if I bid too high, then I only pay what I would of needed to in order to win and keep the auction. Essentially, I thought my bid price was my max bid price. Apparently, according to my bills and several experiments I've done - this is not the case. They charge me for whatever I bid even when I know there is no one else around to counter bid me. I needed to clarify that, but let me get back to the main point: Let's say I'm bidding $0.50, competitor comes in and bids 0.55 cents. I get kicked off. I want to have it to where I'd set a maximum I'm willing to pay (let's say $1.00 here), and then when competitor comes in and tries to bid $.55, my bid is dynamically adjusted to beat his at $0.56 up until he breaks my $1.00 threshold. I've been reading the guides and although they are more or less straightforward, I feel like they leave a few holes in them that end up confusing me. Like, for instance, where do I input said command or when do I do it? Maybe I'm just tech illiterate and need help deciphering these guides. A good start for someone willing to answer/help me decipher this problem would be here: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-as-update-bid.html

• linux intrusion detection software

  - by Sam Hammamy

  I have an Ubuntu VPS that I use for practice and deploying prototypes as I am a python developer. I recently started teaching my self sys admin tasks, like installing OpenLDAP. I happened to turn off the ufw firewall for just a minute, and when I ran an netstat command, I saw a foreign ip connected to ssh that I traced to china. I'd like to know a few things: 1) Is there any good network intrusion detection software, such that if any IP that's outside a specific range connects to the VPN, I can be notified? -- I am thinking about scripting this, but I'm pretty sure there's something useful out there and I believe in the wisdom of crowds. 2) How did this person gain access to my server? Is it because my firewall was down? Or is it because they browsed my LDAP directory and from there figured out a way to connect (there was a clear text password in the tree but it wasn't one used by the server's sshd)?

• Pass parameters to a script securely

  - by codeholic

  What is the best way to pass parameters to a forked script securely? E. g. passing parameters through command line operands is not secure, since someone who has an account on the host can run ps and see them. Unnamed pipe is quite secure, as far as I understand, isn't it? I mean, passing parameters to STDIN of the forked process. What about passing parameters in environment vars? Is it secure? What about passing parameters by other means I didn't mention?

• What are the common Linux commands for SAN-related activities? How do I check if a LUN is attached to the computer?

  - by Nishant

  How do I check if a LUN has been presented to my server? What are the Linux commands for that? Do the LUNs show up in a fdisk -l command like a normal /dev/sda gets listed? What are other commands associated with general SAN related checks in Linux? What is WWN and how does that have any relevance? If we have LUNs, what is the use of multipathing? Bit lengthy but I am not able to get a grasp on the topic. Any help would be appreciated.

• How do I get a different type of scrollbars in 12.04? [closed]

  - by Joseph Garvin

  Possible Duplicate: How do I disable overlay scrollbars? By default 12.04 uses overlay scroll bars that do not suit my taste, and every method I've found so far of disabling them makes them broken in a different way. When I was using 11.10 this wasn't a problem because I could still change the GTK theme. In 12.04, the Appearance settings only contain a few stock themes, and other than the special purpose contrast ones they all have the overlay scroll bars. If I aptitude search gtk3 | grep theme I get no results so there appears to be no packaged alternative either. Most suggestions I've seen for disabling the overlay scroll bars involve uninstalling packages or editing files as root. I want to disable them just for the current user, not for everyone on the whole box; as should be the case for any theme/display setting. There is a gsettings command that temporarily disables the overlay scrollbars just for the current user, but this has two problems of its own: The setting doesn't stick after log off. Because who would want to save settings? The scroll bars put in place have no contrast. They have a black scroller on a black background and are completely unusable. In short what I'd like to know is how to disable overlay scroll bars such that: My preference is user specific. My preference is actually saved. The scroller can actually be seen against the background without having to use a special high contrast theme that makes my whole desktop look like a negative photo from Tron.

• Trouble "turning off" dialtone in Exchange 2010

  - by makerofthings7

  Given that there are two ways to enable dial tone, I'm having trouble turing it off. The two ways I'm aware of are: Dismount the database, delete it or rename it, mount it, Exchange will prompt for a dial tone creation. Run the command: Get-Mailbox -Database DB1 | Set-Mailbox -Database DTDB1 as described here Both options should result in Outlook "thinking" it's in dial tone mode. Since my goal is to shut off dial tone, I think I need to learn the specific, technical parameters that "tell" Outlook that it is in dial tone mode. Question How can I turn off dial tone for a given database? What tells outlook that it's in dial tone mode?

• How do I configure SSH on OS X?

  - by cwd

  I'm trying to SSH from one Mac running OS X 10.6 to another. Seems to work fine via a password, but I can't get it to use a RSA key instead. Where is the ssh configuration file on OS X and what is the command to reload SSH? Update What I'm asking is how to configured advanced options. For example, on Ubuntu there is a ssh config file at /etc/ssh/sshd_config and if you do something like change the port or disable password authentication for a particular user (PasswordAuthentication no) you need to run /etc/init.d/ssh reload to reload the config. I didn't see that file on OS X, so was just wondering where it was. I am aware of the ~/.ssh ~/.ssh/authorized_keys and `~/.ssh/config

• Unable to login into CentOS

  - by Rendl

  I had setup a multinode cluster using CentOS with VMware yesterday. Today when I reboot the nodes I get the below error on startup. "there is a problem with the configuration server status 256 centOS" (/usr/libexec/gconf-sanity-check-2 ) I am unable to login as root or any user as the screen is frozen. The solutions online is to change the permissions for some tmp files. My problem is I am unable to access the terminal as I cannot login. Also on reboot I do not have any recovery options in CentOS. I only see command line GRUB. I am new to linux and Hadoop.Pls help asap.

• How do I mount a sparse disk image permanently?

  - by Mike

  On Mac OS X 10.6.7, when I mount a sparse disk image (either by double-clicking it or using hdid from the command line), the image: Appears on my desktop Needs to be re-mounted every time I log in I'd like to set up the equivalent of an /etc/fstab which will mount the image when the system boots, and make it permanent - so I don't have to worry if my symbolic links will resolve or not. Is this more trouble than it's worth on a Mac? I noticed that there is no /etc/fstab, and /etc/fstab.hd contains a dire warning: IGNORE THIS FILE. This file does nothing, contains no useful data, and might go away in future releases. Do not depend on this file or its contents. I tried sudo hdid -notremovable <image>, which seemed like half of what I wanted (according to man hdid), but it failed with an error: hdid: attach failed - no mountable file systems.

• How to modify partitions after install?

  - by ChocoDeveloper

  I wanted to have Ubuntu with full disk encryption on one big partition, and Windows on a small one. In 12.04, only the Server Edition installer has full disk encryption, so I used that and then installed ubuntu-desktop. When it asked for the size, I reduced it from ~999GB to ~750gb. Now after the install, on both gparted and disk utility I see /dev/sda2 taking ~931GB, and nothing unallocated, so I can't create a partition for windows. I got the size right, because when I right-click inside a folder, then hit 'properties', I see Free space: ~690GB (I don't know why it's not ~750GB, but at least it's not 900). The command df -h shows the same. So what can I do? Normally I would just resize a partition with gparted to create unallocated space, then create the partition. But here I have two problems: gparted does not seem to be showing the correct values, and also it says it does not support LUKS so I'm afraid it will mess things up. Any thoughts?

• How do I install the vi text editor ONLY on my Cygwin installation?

  - by gath

  I have managed to install the Cygwin on my Windows Vista machine. I installed using the default settings. When I try to do vi in the Bash shell, Bash tells me command not found. I believe I need to install the Cygwin editors package which include the vi editor. The nightmare is every time I run the Cygwin setup and select ONLY the editors package and specifically the Vim and select install, Cygwin setup tries to install all other packages, very frustrating!! Is there an easier way of installing just a single package using the Cygwin setup utility?

• Change Keybindings (hardware to software)

  - by Daniel

  I ran a search for this, but the answers I saw were referring to something altogether different than what I'm asking for. So let me clarify: I'm not asking how to change key-combo shortcuts. I'm asking--how do you actually change what your computer thinks you did when you press a given key? An example of what I mean (and the reason I'm asking). I'm a Chrome user, and I use Windows alongside Ubuntu. I own a Lenovo Thinkpad T61p--it came with my scholarship package, and I would have shopped for a nice computer if I could have. The T61p has two buttons above the left and right arrow keys that relate to browser commands to go back and forth one page. This is extremely frustrating for me, as I use the arrow keys, and a single accidental keystroke will catch me going back a page, losing temporary data, and yelling at my stupid keyboard. At the same time, I'm the type of person who keeps way too many tabs open. Chrome doesn't let me refigure keyboard shortcuts, and the only way it allows you to switch between tabs are ctrl+tab and ctrl+shift+tab, and ctrl+page up/down. I was using Notepad++, and they had finally found the solution to both problems! The page back and forth keys functioned as tab back and forth keys. I went through quite some effort to learn how to change the keybindings in Windows. The page back and page forward keys are now the page up and page down keys, respectively, and if I hit control, they let me switch tabs easily, and rather pleasantly. And if I hit the keys by accident, no harm, no foul. Alas, I'm in Ubuntu now, and I need to go through the process again. And while I couldn't just find the answer online, like I did for Windows, I know Ubuntu has nice, supportive communities like this one, where, hopefully, somebody can tell me how to do either what I did in Windows, or directly make it so that my computer changes tabs when I hit those buttons (removing the ctrl button from the tab-changing command).

• how to clone a physical "individual partition" vmdk into a "local" (file-based) vmdk?

  - by BJH

  Hello. I have a physical disk with a small (60GB) partition containing my guest OS. The physical disk also contains a large (240GB) block of unpartitioned space. My vmdk is defined as a physical "individual partition". I want to convert the source physical "individual partition" vmdk into a local (file-based) vmdk. The command - vmware-vdiskmanager -r sourcevmdk targetvmdk -t 2 creates a 300GB vmdk that includes both the desired 60GB "individual partition" and the 240GB of useless unpartitioned space ! How can I create a local vmdk with just the individual partition?

• File/folder Write/Delete wise, is my server secure?

  - by acidzombie24

  I wanted to know if someone got access to my server by using a nonroot account, how much damage can he do? After i su someuser I used this command to find all files and folders that are writeable. find / -writable >> list.txt Here is the result. Its most /dev/something and /proc/something and these /var/lock /var/run/mysqld/mysqld.sock /var/tmp /var/lib/php5 Is my system secure? /var/tmp makes sense but i am unsure why this user has write access to those folders. Should i change them? stat /var/lib/php5 gives me 1733 which is odd. Why write access? why no read? is this some kind of weird use of a temp file?

• Building modules with linux kernel for custom flavor

  - by Chandan Apsangi

  I followed the instructions given in the link: http://blog.avirtualhome.com/how-to-compile-a-new-ubuntu-11-04-natty-kernel/ for building a custom kernel and booting it. Everything works fine, except that when building it, I used the option skipmodule=true (as given in this link), so I guess the modules are not built for this kernel. I'm saying this because after I installed the image (using dpkg -i), when I run 'ls -l' in the /lib/modules/2.6.38-11-i5 folder, all the files/folders except the 'kernel' folder have got updated (Btw, I had built it last time and it had worked fine,this is an update on the same kernel source). So is there some option/command that I missed that exports the modules as well? Thanks for your help.

• Windows 8 - uninstall AppFabric?

  - by downatone

  I recently upgraded from Win 7 - Win 8. AppFabric was not one of the programs that came up as being incompatible when I ran the upgrade wizard, so I did not uninstall it. Now whenever I goto "Add or remove features" I get the following error: --------------------------- Windows Server AppFabric Setup Wizard --------------------------- Windows Server AppFabric is not supported on current operating system Windows 8 Pro(version 6.2.9200.0). Please refer to installation guide for the list of supported operating systems. --------------------------- OK --------------------------- Unfortunately the only way to uninstall AppFabric is via the "Add or remove features" - does anyone know a commandline command to kick the uninstall so I can at least access "Add or remove features"?

  I have been using Ubuntu 11.04 on DELL Inspiron 14R (N5010) laptop for last three months. Before I switch to ubuntu my laptop battery used to give 2.5 hrs to 3 hrs back-up.

• rsync assigns deny permission

  - by user773478

  Currently a script is used to copy files using rsync (version 2.6.9 protocol version 29) from Linux/Unix servers to W2K3 server using very basic command such as "rsync -v source_server::share_name/file_name /cygdrive///file_name" The script further makes copy of this downloaded file for other purposes. This is part of a larger middleware that is being moved to new hardware on W2K8R2 Second part of making copy of the file does not work using more recent rsync client version 3.0.7 protocol version 30 (shows up as cwRsync in add/remove programs) Reason being rsync assigns special permissions to file that includes deny. The user (service account) which downloads the file is in local admin group. The file can be copied elsewhere using rsync. It can be deleted. But cannot be opened or copied locally by same user as deny permission supersedes.

• how can I get back /usr/local/bin/mysql on Snow Leopard?

  From terminal and trying to uninstall macports, I ran a command, rm -rf / macports...., that erased bunch of stuff. I feel ashamed about this, not realizing the space after /. Since then, mysql is running but I cannot execute any of the mysql commands because it is not under /usr/local/bin/ I went ahead an reinstall mysql but without luck. What steps do you recommend on doing in order to be able to run mysql, mysqlduml, mysqladmin, from terminal? I can access databases from phpmyadmin, so mysql is running, don't ask me how.

• Google Chrome with strange behavior

  - by user72274

  I'm former Chromium-browser user, but after not upgrading the PPA for 2 months, I switched to Google Chrome browser yesterday. Everything is okay, except some strange behavior on some pages and crashing after loading "chrome://" configuration pages. The best known website with strange behavior is youtube, there is a picture what I see: When I open user menu in top right corner, it crashes that way and even after closing the menu, some parts of menu stay display. You may say it's Youtube problem, no, I have this problem at least on three other websites, here it is on Imgur: The problem isn't for the whole side, sometimes it happens from the middle of the screen. The interesting part is that it happens everytime in the same distance from the right border. When I check the DOM elements with the Developer tool, the overlay which shows element's position is rendered how it should be. What is more, if there is anchor after the crashed area, it works after clicking on it. Selecting text in crashed page is impossible. I hope there is enough information to give me an advice, thanks in advance. :) EDIT: Here is what the browser posted in "chrome://gpu-internals/": Graphics Feature Status Canvas: Software only, hardware acceleration unavailable Compositing: Hardware accelerated 3D CSS: Hardware accelerated CSS Animation: Software animated.

• "shell not found" on start of backtrack 5

  - by Jor-el

  I am using backtrack5 in VMware on my system. I was trying to change my default shell to ksh. After executing the 'chsh' command. On restarting the OS, it shows "Cannot execute ksh: no such file or directory", which apparently because of giving a bad path while changing shell. Because of this I am not able to start the OS, as I have no terminal to interact with (cannot start the GUI). Now I need to restore the previous shell, but I don't have any access to the terminal. Thanks for the help.

• Partition tool with console UI (as in server installation)?

  - by lepe

  Back in 2006, Ray (3DLover) posted the same question in: http://ubuntuforums.org/showthread.php?t=309680 but none of the answers were really useful. Now with a little help from AskUbuntu community, I would like to repeat his question again to see if this time it can be answered correctly. So this is the question (and what I wish too): I'm looking for a UI tool for managing partitions in a console. I have installed Ubuntu Server, so I don't have X Windows at all. fdisk and sfdisk are entirely command line. parted is slightly better, but it's not really a UI. cfdisk has somewhat of a UI, but it only works on one disk at a time, and there's no advanced options like configuring LVM or RAID. Just partitioning. I love the partition tool that is available during the OS install procedure. You can partition, configure RAID's and LMV sets. It can format the partitions with several different file systems, it can set labels, mount options and it can insert your volumes into your fstab. Is this tool available as a stand-alone program? I can't find it anywhere. I think it's called parted_server, but I can't find much information about where to get it. In the past, I have run the Ubuntu install procedure just to use the partition manager that comes with it. (canceling the install after making my partition edits) Anyone help me on this? Thanks -Ray Thanks in advance.

• How do I get rid of the Cisco CP one-time user message on a Cisco 2901 router?

  - by user65712

  I get this message on a new 2901 Cisco router: Cisco Configuration Professional (Cisco CP) is installed on this device and it provides the default username "cisco" for one-time use. If you have already used the username "cisco" to login to the router and your IOS image supports the "one-time" user option, then this username has already expired. You will not be able to login to the router with this username after you exit this session. It is strongly suggested that you create a new username with a privilege level of 15 using the following command. username <myuser> privilege 15 secret 0 <mypassword> Replace and with the username and password you want to use. It appears every time I login and everytime I show run. I already set up my username. How do I turn it off?
