• Routing traffic to another internal network

  - by Jason

  OK, so here is the scenario. I have 4 Locations connected with an MPLS. I have installed an ASA at the primary location which is 10.20.1.0. Traffic is fine internally and to the world, however... I can't route traffic over the MPLS to another network. It is being blocked by an implicit deny rule even though there is a rule to allow any to any less secure interface (it should be using the same interface in/out, right?). I have a static route for the network in and the ASA can ping it - Just not traffic on the internal network of the ASA. -Jason

• Secure PHP environments with PHP-FPM and SFTP

  - by pdd

  I'd like to set up secure environments for a small number of untrusted PHP websites on a Debian server. Right now everything runs on the same Apache2 with mod_php5 and vsftpd for administrative file access, so there is room for improvement. The idea is to use nginx instead of apache, SFTP through OpenSSH instead of vsftpd and chrooted (in sshd_config), individual users for each website with their own pool of PHP processes. All these users and nginx are part of the same group. Now in theory I can set 700 permissions on all PHP scripts and 750 on static files that nginx has to serve up. Theoretically, if a website is compromised all the other users' data is safe, right? Are there better solutions that require less setup time and memory per website? Cheers

• Top ten security tips for non-technical users

  - by Justin

  I'm giving a presentation later this week to the staff at the company where I work. The goal of the presentation is to serve as a refresher/remidner of good practices that can help keep our network secure. The audience is made up of both programmers and non-technical staff, so the presentation is geared for non-technical users. I want part of this presentation to be a top list of "tips". The list needs to be short (to encourage memory) and be specific and relevant to the user. I have the following five items so far: Never open an attachment you didn't expect Only download software from a trusted source, like download.com Do not distribute passwords when requested via phone or email Be wary of social engineering Do not store sensitive data on an FTP server Some clarifications: This is for our work network These need to be "best practices" tips for the end-user, not IT policy We have backups, OS patches, firewall, AV, etc, all centrally managed This is for a small business (less than 25 people) I have two questions: Do you suggest any additional items? Do you suggest any changes to existing items?

• Do the amount of CUDA cores matter for Sony Vegas

  - by Saif Bechan

  I am building a new PC, and I am wondering if I am making the right choices. The PC will mainly be used for video editing, and mainly in Sony Vegas. Now I have the choice of going with a video that that has more of less CUDO cores. To be precise I am choosing between a Ti and non-Ti version of an nVidea video card. Now I have read that sony vegas can partially use the CUDA cores to it's benefit, but not that much, and only if you use GPU acceleration. On the other hand I have heard it's better to leave GPU acceleration off as it will effect the quality of the output. Making it so that the CUDA cores actually don't make much of a difference after all.

• Better antivirus for Windows Server 2008 R2 x64 VPS

  - by raja

  I have only one VPS with Windows Server 2008 R2 x64 and want to buy an Antivirus. I tried NOD32 but they do not give less than 5 users in business edition (I have only one server). Kaspersky may be another solution but whether should i go for Internet Security or Anti-virus? I have few website hosted on this server and user have ability to upload .jpg, .gif, .zip files in few of the folders. Apart from above two any other suggestions on Antivirus that works well on above configuration and available for only one user? Thanks

• Run a MongoDB configuration server without 3GB of journal files

  - by Thilo

  For a production sharded MongoDB installation we need 3 configuration servers. According to the documentation "the config server mongod process is fairly lightweight and can be ran on machines performing other work". However, in the default configuration, they all have journalling enabled, and with preallocation this takes up 3 GB of disk space. I assume that the actual data and transaction volume of a config server is quite small, so that this seems a bit too much. Is there a way to (safely!) run these config servers with much less disk use for the journal? Do I need journalling at all on config servers? Can I set the journal size to be smaller?

• Xeon X5550 vs Six-core Opteron for database server

  - by gregmac

  I'm specing out a database server, and the price works out to be reasonably close between an Intel X5550 Quad-core and an AMD 2425HE (2.1Ghz) Six-core Opteron. I've been looking for some comparisons between the two, but the only thing useful I've found is an AnandTech Review of the 2435 which compares it to Intel Xeons, but concludes they both have their place. My load is MS SQL Server 2008, with an OLTP database that has about an equal amount of reading/writing (and it's a reasonably heavy load). So my question is, what is going to work better in this situation, assuming the drives are the same: Xeon X5550, with 16GB 1333Mhz RAM (Dell R510) or an Opteron 2425HE (2.1Ghz) or 2439SE (2.8Ghz) with 16GB of 800Mhz RAM? (Dell 2970) Note: the 2439 adds $500, but the overall pricing works out that it's not that much more than the R510. Using the 2425HE, the Dell 2970 server is slightly less than the similarly-equipped R510). If it adds a decent amount of performance, it's worthwhile to go faster. (single CPU, in both cases).

• Using Performance Monitor To Get IIS7 Response Turnaround Time

  - by alphadogg

  I have a MVC2 web application on W2KR2/IIS7 that I'd like to benchmark/monitor. Some XHR requests by a browser-based client are suddenly taking 8-10 sec when they used to take much less time (as per Chrome Developer Tool timings). The underlying SQL Server queries, using the same params, runs in 1.4s according to total execution time client statistics from SSMS. I'm assuming that there are various counters that can specifically dissect time taken/waiting/processing between IIS7 itself and the web application? For example, can I check how long it takes to get a response from IIS7 app and DB? How about how long it takes to serve IIS7?

• How can I use the shell to make my mp3s a Shoutcast source?

  - by ChasonDehsotel

  I'm looking to stream a directory of mp3s from my audio source (Debian server) to my Shoutcast server. The idea is to have an archive playing in the instance that someone isn't broadcasting live. I'm not sure how to continue. I started with extensive Google-ing, and was unable to come up with a solution. Evan Carroll suggested I try here. I appreciate any insight y'all may have. __ On a side note, "users with less than 100 reputation can't create new tags. The tags 'shoutcast-source shoutcast broadcasting' are new. Try using existing tags instead." -- Who can create these?

• Options to optimize lotus notes 8.5.X

  - by Jakub

  Has anyone found actually useful optimization methods for the bulky, fat, eclipse giant, nuissance that is Lotus Notes 8.5? I want it to be fast, and not eat up system resources like crazy while I run it ALL day (as it is my company's corporate mail / cal / scheduling solution). I've tried various hacks for the JVM heap size (if I recall correctly). None really bring a performance improvement. I have a dual core cpu, if that helps (I tried going the route of optimizing JAVA for 2 cores in hopes it would work, but seen no speed improvement). Notes is just sooo bloated, anyone have any suggestions to optimize/mod this thing so it is more responsive and less of a resource hog. Note: I don't want to switch to the web version, or the standard stripped down versions, I am aware of those, I just cannot since we don't run those internally for the company.

• Calibrating Displays in Boot Camp 3.0 on MacBook with external display

  - by Brian Reiter

  The LED display on my MacBook Pro is very blue-ish without correction. In OS X the advanced mode of the display color calibration tool is excellent and I can largely color-correct the display. Windows 7 incorporates a color calibration tool but it is less powerful. It largely consists of a software gamma correction tool and color charts to use with the hardware controls on your display (which don't exist on a notebook or an apple external display). How can I color-correct Windows in Boot Camp to match the OS X correction without using a Spyder or other special calibration hardware?

• How can I download videos from this website?

  - by user82171

  I wanted to downlaod some of these short videos from chinadaily.com. For example, http://video.chinadaily.com.cn/2013/1012/1388.shtml I have tried NetVideoHunter with Firefox, which works for me for many other sites. But here, NetVideoHunter shows me very small segments of less than 200 KB and when I try to play them (in the NVH panel itself), it says 'Connecting' and then 'Stream not found'. I have seen other question on SuperUser about how to download a Flash video. The URL shows something likes this for each segment. definst/mp4:ugc/2013/1012/1762_video_9829_6_1381544755203.mp4/media_b580746_w1896927931.abst/Seg1-Frag80"http://videostream.chinadaily.com.cn:1935/app_1/definst/mp4:ugc/2013/1012/1762_video_9829_6_1381544755203.mp4/media_b580746_w1896927931.abst/Seg1-Frag80 Is there a way to download these videos? Or is this method of segmenting done to prevent downloads? Thank you

• Wii game bought in US, will it work on a PAL console in Europe?

  - by Stijn Sanders

  I can't seem to find a European online outlet that offers this Wii game I'm looking for. If I would buy it from a web-shop in the US, could I end up with a game that doesn't work well with my console? I'm worried because all games I have for the Wii so far have a prominent mention of "PAL" on the cover. I didn't notice "NTSC" on the photo's of the cover online, but I'm worried none the less. (And thought I'd ask it here first...) Also, does anyone happen to know if Belgian customs would add tax to shipments like this coming in from the US?

• GIMP Slow Startup

  - by muntoo

  Is there any way to speed up GIMP's startup time on Windows Vista Home Premium 32-Bit 1.6 [Dual] Intel Processors? On XP [different computer], it loads in less than 3 seconds. On Vista, it takes 20 seconds: 2 Seconds (other - fonts, brushes, etc) 18 Seconds (extension-script-fu) It just freezes at extension-script-fu. Looking at ProcessExplorer (or Task Manager, whatever), I see that it's not taking any CPU. EDIT: it does seem to be taking 50% of the CPU. It gets stuck for about 18 seconds, then starts working again, and the actual GIMP program pops up [...finally]. I have the latest stable version running (I think). I tried it with XP SP2 Compatibiliy mode and/or Run As Administrator, but that didn't help. EDIT: One way would be to disable script-fu. Does anyone know how to disable it at startup? (NOTE: Just wanted to point out that the title and the tags are the same. :D )

• Mouse-usable alt-tab for windows 7

  - by Florian Peschka

  I'm using Windows 7 with ye good olde Windows 2000 style (I favor usability and space over fancy-pants aero and effects) and am looking for a way I can make the ALT-TAB-Control interactable with my mouse. I generally have many many windows open, and pressing tab or shift-tab over and over again begings to really frustrate me, if i want to reach a certain program. Of course, I could just select the program on my taskbar, but that takes even longer. I really like the way mac os x has its alt-tab menu - more or less exactly the same, but I can select the program with my mouse. Is there something like that for my environment?

• How to make Outlook Calendar reminders pop up in Windows 7

  - by thursdaysgeek

  I'm just starting to use Windows 7 and I want to know how to make my Outlook reminders pop up and show themselves. They keep opening discretely, quietly as just another Outlook entry on the taskbar. And I keep overlooking them, because they pop up behind everything else. How do I make them less easy to overlook? (Yeah, usually you don't want obnoxious apps that push themselves to the forefront. But there are a few places where I do want that, and Outlook calendar reminders are one of them.)

• Sar data not collected for 10 minutes

  - by Ichorus

  We have a RedHat server whose only job is to run a JBoss server. Monitors said that memory usage spiked (we have the JVM limited to far less than the total memory on the system) and JBoss crashed. We restarted and everything seems ok now. Odd thing is that sar data for 10 min leading up to the crash is simply not there. Load average got up to the 50s. I have seen severely busy systems (350+ Load Average) still collect sar data. Does anyone have any idea what could cause sar to stop collecting data?

• syslogd: Logfile format (not configuration format)

  - by chris_l

  Hi, I'd like to parse logfiles. Is the logfile format of syslogd the same for all systems? On my system (Debian Lenny), it's: Mar 7 04:22:40 my-host-name ... (I'm not much interested in the ... part) Can I rely on this? And is there maybe some more-or-less official description? The manpage of syslogd describes the config format, but not the logfile format. Ideally, the description would give the fields official names like (date, time, host, entry) or (datetime, hostname, message). Maybe additionally some regular expressions. I'd like to use the names and regexes in my script, to avoid an unnecessary deviation from the standard, and to make sure, that the script runs everywhere. Thanks Chris

• How to add nvidia drivers after previous failure with linux mint?

  - by LessThanMe

  Before today, I had perfectly good drivers from nvidia for my linux mint (15) box. I decided to update it because my performance in TF2 is less than stellar, and then things went south. I used synaptic to install nvidia-331 and then rebooted, but when I selected Mint in GRUB I waited...and waited...and waited. Nothing happened, but the display stayed on (a completely black video was being output). So I went into recovery mode from GRUB, went to root access, and apt-get remove --purge nvidia*'d my way out of that mess, and installed nvidia-common. Now my performance in graphic intensive stuff (read: games, blender) sucks, so I've been through the same thing a few times trying to re-install nvidia-current. I just want to get it back how it was. Thanks for any help! Nvidia GTX 560

• Differences in memory consumption between two identical D7 sites?

  - by aendrew

  I'm running Drupal on a news site that has a lot of different View blocks on the front page (~5 total, all cached). In trying to reduce the memory footprint of the site, I've checked out source from SVN to a local development install to try and convert some of those blocks into more optimized code. Here's the weird thing. Devel module lists memory consumption at 50mb on the Production site (Running Nginx, PHP 5.2.17, XCache and Zend Optimizer.) but only 14mb on my development site (Running Apache2, PHP 5.2.13 and XCache). These are nearly-identical versions of the same site — frankly, the Production site should use even less memory as I've disabled some of the modules running on the Dev site. Any idea why this might be the case?

• Has anyones successfully configured mutt for GMail on FreeBSD? If so, how?

  - by Hank Gay

  I've tried following the instructions here and here. Currently, I can read email from my GMail account, but not send—this is on a personal computer, so even if I configured Sendmail, I doubt any of the mail would survive the spam filter gauntlet. Both guides seem to require the --enable-smtp option for mutt, which I don't think is being exposed by ports. I've tried the mutt and mutt-devel ports and neither seem to give me that option. On a far less important note, I also haven't been able to change folders, e.g., I get told that Sent Mail is not a valid folder when I attempt to go into it. If you can troubleshoot this problem, it's pure gravy. I really only care about sending. Thanks, Hank

• Messages don't always appear in Mail.app

  - by MikeHoss

  My wife and I share a Mac and use different accounts. We both use Apple's standard Mail.app. We can also get to our email accounts via SquirrelMail that our webhost provides. Both SquirrelMail and Mail.app are connecting via IMAP. My wife was the first to notice that not all messages were getting to the Mail.app. She would check the Mac (our main machine) and then a little while later check mail from another machine via SquirrelMail and see messages there that should have been on the Mac. She would go back and those messages would never show up. Lately, I have been seeing the same thing, though less often. I can't reproduce it, or just look at a message to see if they haven't been moved over. I've looked in Junk, etc. and the Mac simply never sees those messages via IMAP. Does anyone have a guess to something I could poke around at?

• High CPU usage on Linux machine

  - by user305210

  I have a piece of java code running on two different machines, but on one of the linux machines, the code uses alot of CPU (close to 100% cpu usage). On the other machine the same code uses less cpu (under 3 to 4%). The machine where cpu usage is high, is a more powerful machine, more CPU and and more memory. This has started happening recently and performance on the machine with high cpu usage has degraded significantly. I am wondering if anyone has any ideas why something like this could happen, possible causes behind this etc. any guesses? No recent changes in hardware were made, no recent code updates... Thank you.

• Paste a list of dates in format of "mm/dd/yy" to iWork-Numbers

  - by David.Chu.ca

  I have trouble to paste a list of strings in the format of 'mm/dd/yy' into iWork-Numbers. For example, I have a list of strings(text in VIM): 04/01/10 04/03/10 04/13/10 I copy those strings and then paste into my iWork-Numbers worksheet. The result will be: 2004-01-10 2004-03-10 04/13/10 It looks like that Numbers (mac workseet application in iWork) tries to convert the first two digits into year, then the next two into month if less than 12 and last two digits to a day, for the first two rows. For the third(04/13/10), since the middle two digits are 13 and cannot be a month, then this row is pasted as it is (actually it is what I need). Is there any way to paste whatever as they are, without any "smart date conversion"? Do I have to change settings in Numberers or Mac OS's System preference?

• How to back up server with rsync, preserving ownership/permissions without root login

  - by olilarkin

  I am setting up a backup server on which I want to run rsync over ssh to backup content on other servers every night. I would like to set up ssh keys to make it password-less, but I want to preserve ownership of files and permissions. There are a number of users on the server to be backed up which won't all exist on the backup server. What would be the best way to do this? I guess the backup job will need to connect as root to , but I don't want to enable root ssh access on the servers. thanks for any tips, oli ps, all servers are running UBUNTU Server 12.04 LTS and are behind a university firewall.
