• Security Resources

  - by dr.pooter

  What types of sites do you visit, on a regular basis, to stay current on information security issues? Some examples from my list include: http://isc.sans.org/ http://www.kaspersky.com/viruswatch3 http://www.schneier.com/blog/ http://blog.fireeye.com/research/ As well as following the security heavyweights on twitter. I'm curious to hear what resources you recommend for daily monitoring. Anything specific to particular operating systems or other software. Are mailing lists still considered valuable. My goal would be to trim the cruft of all the things I'm currently subscribed to and focus on the essentials.

• Resize underlying partitions in mdadm RAID1

  - by kyork

  I have a home built NAS, and I need to slightly reconfigure some of my drive usage. I have an mdadm RAID1 composed of two 3TB drives. Each drive has one ext3 partition that uses the entire drive. I need to shrink the ext3 partition on both drives, and add a second 8GB or so ext3 partition to one, and swap partition of equal size to the other. I think I have the steps figured out, but wanted some confirmation. Resize the mdadm RAID resize2fs /dev/md0 [size] where size is a little larger than the currently used space on the drive Remove one of the drives from the RAID mdadm /dev/md0 --fail /dev/sda1 Resize the removed drive with parted Add the new partition to the drive with parted Restore the drive to the RAID mdadm -a /dev/md0 /dev/sda1 Repeat 2-5 for the other device Resize the RAID to use the full partition mdadm --grow /dev/md0 -z max Is there anything I've missed, or haven't considered?

• Use a MOO/MUD/MUSH for project collaboration?

  - by Clinton Blackmore

  Jeff Atwood recently posted about working with a team of programmers remotely. He spoke of pros and cons and of communicating with the team. One of the comments to his article says: Jeff, have you ever considered running a MOO for this? you can have any features you want to add to a MOO- mailing lists, tasks, and so on. All it takes is a moo server and learning moocode. Leetdoodsnonexistentramblings.blogspot.com on May 9, 2010 2:52 PM It is not clear to me how to contact the commenter (short of signing up for a social networking service I've never heard of), so I thought I'd ask here -- does anyone know what useful things you could do with a MOO (or MUD or MUSH) to promote collaboration on a team?

• Fedora vs Ubuntu to host Subversion and Bugzilla over Apache

  - by Tone

  I'm not interested in a flame war of Ubuntu vs Fedora vs whatever. What I am interested in is whether or not I should move my current Ubuntu server to Fedora. I have been able to get Subversion setup and hosted via Apache over https and it works quite well (I'm a .NET guy so this was all new to me). I'm having trouble though with installing Bugszilla - have run into some issues getting all the perl scripts to run successfully so my questions are: 1) Will Bugszilla will install easier on Fedora? Can I just install a package instead of having to download the tar.gz file and untar it, run perl scripts, etc. 2) Is Fedora considered to be a better production server system? I have no desire for a GUI, just need it to host Subversion, Bugzilla over Apache2, and act as a file and print server for my home network.

• Using DD for disk cloning

  - by roe

  There's been a number of questions regarding disk cloning tools (yes, I did search for it) :) and dd has been suggested at least once. I've already considered using dd myself, mainly because ease of use, and that it's readily available on pretty much all run of the mill bootable linux distributions. To my question, what is the best way to use dd for cloning a disk. I don't have much time to go around, and no test-hardware to play with, so I need to be prepared, and it's pretty much a one-shoot chance to get it done. I did a quick google search, and the first result was an apparent failed attempt. Is there anything I need to do after using dd, i.e. is there anything that CAN'T be read using dd? Thanks!

• How do you create large, growable, shared filesystems on Linux at AWS?

  - by Reece

  What are acceptable/reasonable/best ways to provide large, growable, shared storage at AWS, exposed as a single filesystem? We're currently making 1TB EBS volumes ~biweekly and NFS exporting with no_subtree_check and nohide. In this setup, distinct exports appear under a single mount on the client. This arrangement does not scale well. The options we've considered: LVM2 with ext4. resize2fs is too slow. Btrfs on Linux. not obviously ready for prime time yet. ZFS on Linux. not obviously ready for prime time yet (although LLNL uses it) ZFS on Solaris. future of this combo is uncertain (to me), and new OS in the mix glusterfs. heard mostly good but two scary (and maybe old?) stories. The ideal solution would provide sharing, a single fs view, easy expandability, snapshots, and replication. Thanks for sharing ideas and experience.

• How to control admission policy in vmware HA?

  - by John

  Simple question, I have 3 hosts running 4.1 Essentials Plus with vmware HA. I tried to create several virtual machines that filled 90% of each server's memory capacity. I know that vmware has really sophisticated memory management within virtual machines, but I do not understand how the vCenter can allow me even to power on the virtual machines that exceed the critical memory level, when the host failover can be still handled. Is it due to the fact that virtual machines does not use the memory, so that it is still considered as free, so virtual machines can be powered on ? But what would happen if all VMs would be really using the RAM before the host failure - they could not be migrated to other hosts after the failure. The default behaviour in XenServer is that, it automatically calculates the maximum memory level that can be used within the cluster so that the host failure is still protected. Vmware does the same thing ? The admission policy is enabled. Vmware HA enabled.

• How reliable are Compact Flash drives

  - by bakytn

  For example, USB drives have read/write limits. and they are considered as unreliable and not durable for daily use over many years. My question is, however, about Compact Flash drives. AFAIK they are built almost in the same way as USB flash drives. I was going to use one Compact Flash drive for daily usage and install a lightweight operating system to it (Linux). What kind of limitations do they have? Read/write operations? Just a time? something else? Thank you!

• Does any upgrade version of Visual Studio require an installed development tool?

  - by Will Eddins

  I'm wondering this from a legal standpoint and an installation-issue standpoint. I'm considering pre-ordering Visual Studio 2010 for future use in some home projects, and you cannot pre-order a full version, only an upgrade version. On the preorder page, it says: Eligible for upgrade with any previous version of Visual Studio or any other developer tool. In reality, I think it won't require anything installed, but from a legal standpoint, is this inclusive with development tools such as Eclipse? After installing Windows 7 on this PC, Eclipse is currently the only IDE I have installed. But really anything could be considered a developer tool, such as Notepad++ or Kaxaml. How has this worked in regards to previous upgrade versions?

• Upgrade PHP to 5.3 in Ubuntu Server 8.04 with Plesk 9.5

  - by alcuadrado

  I have a dedicated server with Ubuntu 8.04, and really need to upgrade php to 5.3 version in order to deploy a new version of the system. This version of php is the default one in ubuntu 10.04, so I considered upgrading the OS, but after trying that, I lost my plesk installation, which annoyed my client. I tried adding the dotdeb.org repositories, but don't know why, after running an apt-get upgrade, I get this error: # apt-get upgrade Reading package lists... Done Building dependency tree Reading state information... Done The following packages have been kept back: libapache2-mod-php5 php5 php5-cgi php5-cli php5-common php5-curl php5-gd php5-imap php5-mysql php5-sqlite php5-xsl 0 upgraded, 0 newly installed, 0 to remove and 11 not upgraded. Any idea why is this happenning? Or do you know any alternative method (except compiling my own binaries) to upgrade php or update ubuntu without loosing plesk? Thanks!

• Ignoring GET parameters in Varnish VCL

  - by JamesHarrison

  Okay: I've got a site set up which has some APIs we expose to developers, which are in the format /api/item.xml?type_ids=34,35,37&region_ids=1000002,1000003&key=SOMERANDOMALPHANUM In this URI, type_ids is always set, region_ids and key are optional. The important thing to note is that the key variable does not affect the content of the response. It is used for internal tracking of requests so we can identify people who make slow or otherwise unwanted requests. In Varnish, we have a VCL like this: if (req.http.host ~ "the-site-in-question.com") { if (req.url ~ "^/api/.+\.xml") { unset req.http.cookie; } } We just strip cookies out and let the backend do the rest as far as times are concerned (this is a hackaround since Rails/authlogic sends session cookies with API responses). At present though, any distinct developers are basically hitting different caches since &key=SOMEALPHANUM is considered as part of the Varnish hash for storage. This is obviously not a great solution and I'm trying to work out how to tell Varnish to ignore that part of the URI.

• Email Servers that Abstracts Mailbox Concepts [on hold]

  - by David

  Lately I've been really interested in doing some very unique things with email most of which rely on a SMTP and POP or IMAP server that gives the administrator an API to create arbitrary methods for email storage, notifications, or delivery. What I'm looking for would be analogous to mod_php and apache where apache handles the delivery protocol and php handles the content creation and storage. I've considered making my own, as those three protocols are quite simple, but I'm always nervous about putting my code public facing especially when it's at that low of a level. So are there any email servers that allow for this much arbitrary control over email delivery, fetching, and receiving.

• Customizable mail server - what are my options? [closed]

  - by disappearedng

  This question was originally on SO but it was closed since it is considered off topic. I am interested to build a mail service that allows you to incorporate custom logic in the your mail server. For example, user A can reply to [email protected] once and subsequent emails from user A to [email protected] will not go through until certain actions are taken. I am looking for something simple and customizable, preferably open-sourced. I am fluent in most modern languages. What email servers do you guys recommend for this? Mailgun looks promising, but are there any simpler options?

• Do superuser's prefer business grade or consumer grade PCs?

  - by joelhaus

  Having burned through a number of consumer grade laptops in recent years, I'm wondering if the additional cost of a business grade computer is a worth while investment. I'm considering getting a laptop with slightly lower specs to justify the added cost. The primary benefits I see are: (i) the notebook will be more reliable, (ii) have a longer life and (iii) the warranty (parts and labor) will be 3 years instead of 1 year. Are there any other considerations one should keep in mind when shopping for a business grade PC? Is purchasing direct from the manufacturer wise or are there other options that should be considered too? Thanks in advance!

• Is it OK to use images of GPD'd code in a CC 3.0 BY video?

  - by marcusw

  I am making a video in which I would like to use pictures of some Linux Kernel code. I am looking to release the finished product under the CC 3.0 BY license, but the Kernel is released under the GPL, which would not allow this if the code is in text format. However, since it will be in low-resolution, incredibly incomplete, non-usable, non-compilable, non-editable (at least without lots of finagling) format, would this constitute fair use or find another loophole to slip through? Thanks for the help, I will understand if this is considered off topic.

• Google Accounts

  - by Alex

  Hi all, I need to setup a bunch of accounts (~50) with Google which will later be hooked up to Analytics and the Webmaster tools and I will access them via their APIs. The problem is that Google will stop me from making accounts at a certain point because it thinks I'm spamming it. I've tried bypassing the issue by proxying through Tor, but that didn't work (I suspect the Tor nodes are already abused and blacklisted). I also drove around town with my iPhone hopping towers trying to setup accounts. Also didn't work. Phone verification also doesn't work because my phone is already linked to too many accounts... So, I figure it's time to ask. How can I continue to setup Google accounts (NOT GMail...) without being considered a spammer? If there's a service from Google to whitelist my IP, even for a fee, I would be glad to sign up for it. Any suggestions will be appreciated!

• Dealing with different usernames when mounting removable media in Linux

  - by dimatura

  I have a laptop in which my username is, say, "foo". I have an external drive, formatted with Ext4, for which all files are owned by "foo" (at a filesystem level). Now, I have a desktop in which my username is, say, "bar". If I mount this external drive in this computer the files are considered to not be owned by "bar". This makes sense, but it is annoying because their bits mode are set so that only the owner can modify/delete them. What's the cleanest way to deal with this? Create a group with "foo" and "bar" and add group modification permissions?

• Social-Networking Startup, Hosting Plan

  - by pws5068

  I've created a social networking community which is soon ready to release, and I'm trying to decide on a type of hosting plan. I have considered options such as VPS and Reseller plans. I anticipate (or hope for at least) a significant amount of traffic/bandwidth in the not-too-distant future. If I open a reseller, will I receive the same amount of server lag during busy hours that I do with a shared account? How significant is the profit margin with the reseller option? Aside from generalized "configurability", what advantages merit purchasing a VPS? Is there anything stopping me from reselling space on a VPS account? Features I need Include: PHP, MySql, Unlimited Domains, Ruby on Rails, Remote Database Connections

• Which Linux book for aspiring sysadmin?

  - by Ramy

  I have a co-worker who insists that he will never buy a book unless it is considered "THE" book. So, in this vein, I thought I'd ask what the ultimate Linux book is. I wouldn't quite call myself a complete beginner since I can get around in Linux in general pretty well. But, beyond that, I'm also looking for a book with an eye towards becoming a Sys Admin someday. I saw a Junior Sys Admin position open up recently but with the requisite 2-3 years experience, I may have to wait a little while longer before I'm ready to apply for such a position. Having said all that, I'll summarize my question: What is the ultimate Linux book for someone who is ok with the basic tasks of getting around in Linux but also wants to aim towards full Sys Admin status someday? A few examples of the books I'm considering: Linux-Administration-Beginners-Guide-Fifth Linux-System-Administration Linux-System-Administration EDIT: Before you close this question as a dup, I'd like to say that I'm looking for something that goes deeper than this: Book for linux newbies I already have "Linux in a nutshell"

• What the hell was THAT?!?

  - by Massimo

  My system is Windows XP SP3, updated with the latest patches. The PC is connected to a Cisco 877 ADSL router, which does NAT from the internal network to its single static public IP address. There are no forwarded ports, and the router's management console can only be accessed from the inside. I was doing two things: working on a remote office machine via VPN and browsing some web pages on the Cisco web site. The remote network is absolutely safe (it's a lab network, four virtual servers, no publicly accessible services and no users at all; also, none of what I'm going to describe ever happened there). The Cisco web site... well, I suppose is quite safe, too. Suddenly, something happened. Strange popups appears anywhere; programs claiming they're "antimalware", "antispyware" et so on begins autoinstalling; fake Windows Update and Security Center icons pop up in the system tray. svchost.exe began crashing repeatedly. Then, finally, after some minutes of this... BSOD. And, upon rebooting, BSOD again. Even in safe mode. Ok, that was obviously some virus/trojan/whatever. I had to install a new copy of Windows on another partition to clean things up. I found strange executables, services and DLLs almost anywhere. Amongst the other things, user32.dll and ndis.sys had been replaced. A fake software called "Antimalware Doctor" had been installed. There were services with completely random names or even GUIDs (!), and also ones called "IpSect" and "Darkness". There were executable files without an .exe extension. There were even two boot-class drivers, which I'm quite sure are the ones that finally caused the system to crash. A true massacre. Ok, now the questions: What the hell was that?!? It was something more than a simple virus! How did it manage to attack my computer, as I am behind a firewall and was not doing anything even only potentially harmful on the web at the time?

• Combine Multiple Audio Files into a single higher-quality audio File

  - by namenlos

  BACKGROUND My team gave a demo to a large audience - we recorded the audio of the demo in multiple locations in the room (3) the audio was recorded using cheap laptop microphones I was not involved in the recording of the audio or the demo Both audio files suck in some form the first one is of a recording near the speaker - which clearly gets his voice but the the audience is audience is muffled - also this one is slightly noisy The second recording was done in the middle of the audience - it gets the audience questions clearly but actually gets the speaker rather sometimes well and sometimes poorly (not all the speakers spoke loudly enough to be heard) MY QUESTION Is there any techinque or software which can be used to merge these audio files in such a way that the best qualities of each are preserved. I am NOT asking now to simply merge them together in one track - I've already done that in Audacity and it is certainly better - what I am looking for could be considered closer to how HDR images are created - multiple exposures combined into an enhanced new version which is not simply an average of the inputs. NOTE Am not an "Audio" guy - just a normal user

• Lazy umount or Unmounting a busy disk in Linux

  - by deed02392

  I have read that it is possible to 'umount' a disk that is otherwise busy by using the 'lazy' option. The manpage has this to say about it: umount - unmount file systems -l Lazy unmount. Detach the filesystem from the filesystem hierarchy now, and cleanup all references to the filesystem as soon as it is not busy anymore. This option allows a "busy" filesystem to be unmounted. (Requires kernel 2.4.11 or later.) But what would be the point in that? I considered why we dismount partitions at all: To remove the hardware To perform operations on the filesystem that would be unsafe to do while mounted In either of these cases, all a 'lazy' unmount serves IMHO is to make it more difficult to determine if the disk really is dismounted and you can actually proceed with these actions. The only application for umount -l seems to be for inexperienced users to 'feel' like they've achieved something they haven't. Why would you use a lazy unmount?

• In Nginx can I set Keep-Alive dynamically depending on ssl connection?

  - by ck_

  I would like to avoid having to repeat all the virtualhost server {} blocks in nginx just to have custom ssl settings that vary slightly from plain http requests. Most ssl directives can be placed right in the main block, except one hurdle I cannot find a workaround for: different keep-alive for https vs http Is there any way I can use $scheme to dynamically change the keepalive_timeout ? I've even considered that I can use more_set_input_headers -r 'Keep-Alive: timeout=60'; to conditionally replace the keep-alive timeout only if it already exists, but the problem is $scheme cannot be used in location ie. this is invalid location ^https {}

• Does removing admin rights really mitigate 90% of Critical Windows 7 vulnerabilities found to date?

  - by Jordan Weinstein

  Beyondtrust.com published a report, somewhat recently, claiming among other quite compelling things, "90% of Critical Microsoft Windows 7 Vulnerabilities are Mitigated by Eliminating Admin Rights" Other interesting 'facts' they provide say that these are also mitigated by NOT running as a local admin: 100% of Microsoft Office vulnerabilities reported in 2009 94% of Internet Explorer and 100% of IE 8 vulnerabilities reported in 2009 BUT, reading the first page or so of the report I saw this line: A vulnerability is considered mitigated by removing administrator rights if the following sentence is located in the Security Bulletin’s Mitigating Factors section, ?Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. could be sounds pretty weak to me so and I wondered how valid all this really is. I'm NOT trying to say it's not safer to run without admin rights, I think that is well known. I just wonder if these stats are something you would use as ammo in an argument, or use to sell a change like that (removing users as local admins) to business side? Thoughts? Link to the report (pdf) [should this supposed to be a community wiki?]
