• Ubuntu 13.04 to 13.10: Filesystem check or mount failed [migrated]

  - by SamHuckaby

  I attempted to upgrade from Ubuntu 13.04 to 13.10 today, and mid upgrade the system started flaking out, and eventually locked up entirely. I was forced to restart the computer, and am now unable to get the computer to boot up at all. When I boot currently, it takes me to the GRUB menu, and I can choose to boot normally, or boot in an older version. I have tried several things, which I list below, but no matter what, when I try to finish booting into Ubuntu, I receive the following error: Filesystem check or mount failed. A maintenance shell will now be started. CONTROL-D will terminate this shell and continue booting after re-trying filesystems. Any further errors will be ignored root@ubuntu-computername:~# I have fun fsck -f and everything appears correct, no errors are reported. and it passes all 5 checks. If I run fdisk -l then I get the following information: Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 4096 bytes / 4096 bytes Disk identifier: 0x00010824 Device Boot Start End Blocks Id System /dev/sda1 * 2048 608456703 304227328 83 Linux /dev/sda2 608458750 625141759 8341505 5 Extended Partition 2 does not start on physical sector boundary. /dev/sda5 608458752 625141759 8341504 82 Linux swap / Solaris Disk /dev/sdb: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x0fb4b7e8 Device Boot Start End Blocks Id System /dev/sdb1 8192 625139711 312565760 7 HPFS/NTFS/exFAT I am considering just installing a new OS on the other disk, that currently has nothing on it, and then just attempting to scrape my data off the old disk (thankfully I didn't encrypt the files). Really my question is this: Can I salvage this Ubuntu install, or should I give up and just reinstall?

• What's the state of the art in image upscaling?

  - by monov

  I like to collect cool pics and use them as wallpapers or for other things. Often, artists publish only low-res versions, probably for fear of theft. Example: Gabriel Pulecio's BIRDS Now, if I want to use that as a wallpaper, I'd have to upscale it, and obviously that'd make it look blurry because of the bicubic interpolation. I realize there's no real way to get a high-res version from a low-res pic, because the information is not simply there. That said, I'm wondering if heuristics have been developed for upscaling with less apparent loss of quality. Those would probably be optimized for specific image types. For photorealistic pictures, for cartoons with large flat areas, for pixel art... One algorithm I'm aware of is Seam Carving. It works for some kinds of pics, especially ones with a plain, undetailed or uninteresting background, and a subject that strongly stands out. But it's far from being general-purpose. Applying it to the above pic produces this. It looks quite sharp, but the proportions are horribly distorted because the algorithm is not designed for this kind of pic. Another is Pixel art scaling algorithms. Those are completely unfit for anything other than actual pixel art that's pixelized to begin with. For example, I tried the scale2x windows binary on my pic, but its output was nearly indistinguishable from nearest-neighbour scaling because the algorithm didn't detect any isolated pixely fragments to work from. Something else I tried was: I enlarged the image in Photoshop with bicubic interpolation, then I applied unsharp mask. The result looks pretty bad. The red blotch is actually resized reasonably well, but the dove is far from it. What I'm looking for is some app that makes a best-effort attempt at upscaling any input image while minimizing blurriness. If you know of any, I'll be thankful. Note that the subjective prettiness and sharpness of the result is what matters... the result doesn't need to be completely faithful to the original small image.

• Missing boot files in Windows 8

  - by Alex F. Sherman

  I had a partition with Windows 8 Release Preview, Windows' System Reserved partition and the empty space of the beginning of disk. I moved two partitions to the beginning of disk using Ubuntu Live CD and GParted. After that, the Windows Loader didn't boot and throw an error about missing files. I fixed it using the commands: bootsect /nt60 sys /force /mbr bootrec /rebuildbcd bootrec /fixboot bootrec /fixmbr When I used "Automatic repair" option from "Advanced boot" menu, it throw an error like: Windows can't fix your boot problems. For more information see file C:\Windows\System32\LogFiles\Srt\SrtTrail.txt In this file I found a description of the system repair actions and at the end of file: Boot status indicates that the OS booted successfully. Now, when I use the Advanced boot menu from Windows 8 (PC settings - General - Advanced startup) I receive an error: Restart your PC to try again. It looks like something didn't load correctly. Restarting might fix the problem. If this happens more than once, you might also be able to find help by searching online for the specific error code. Erorr code: 0x8007090. 0x80070490 is the error code ERROR_NOT_FOUND. What are the missing boot files and how can I restore them? List of files in System Reserved Partition: B:\bootmgr B:\BOOTNXT B:\Boot\BCD B:\Boot\BCD.LOG B:\Boot\BCD.LOG1 B:\Boot\BCD.LOG2 B:\Boot\BOOTSTAT.DAT B:\Boot\Fonts B:\Boot\memtest.exe B:\Boot\qps-ploc B:\Boot\Resources B:\Boot\Resources\bootres.dll and many *.mui and *.ttf files.

• DEB: "Provides:" field ignored

  - by Creshal

  I need to replace a package with a custom one, which gets its own name (foo-origpackage). To allow it to be used as drop-in replacement, I added the Provides: origpackage line to the control file. apt-cache show foo-origpackage lists the "Provides" entry just fine. However, when I want to install a file depending on origpackage, it fails ("Package origpackage not installed"). Is there some distinction between "real" and virtual packages I'm missing? EDIT: To be precise, what I want to replace is xen-utils-common for Squeeze.

• Why are FMS logs filled with 'play' event status code 408 for a failed webcast?

  - by Stu Thompson

  Recently we had a live webcast event go horribly wrong. I'm doing the technical post-mortem, with limited information. We know that the hardware encoder (a Digital Rapid Touch Stream Web HDI) was unable to send upstream at a sustained reliable high rate. What we don't know is if the encoder's connection was problematic (Zürich), or that of the streaming server (in Frankfurt). Unfortunately, I've got three different vendors all blaming each other (the CDN who runs the server, the on-site ISP and the on-site encoding team.) In the FMS log files I see a couple of interesting things: Zillions of Status Code 408 on play event entries for clients. Adobe's documentation stats that this "Stream stopped because client disconnected". ("Zillions" would be a ratio of 10 events for every individual IP address.) Several unpublish / (re)publish events per hour for the encoder I'd like to know if all those 408s could tell me with authority that the FMS server was starved for bandwidth, or that the encoding signal was starved (and hence the server was disconnecting clients.) Any clues?

• New Dvds with 99 Title tracks, which one is the correct track?

  - by Mike Fielden

  I have embarked on the task of backing up my DVD collection. I have noticed that some of the newer movies I am attempting to rip contain 99 Title tracks all with approximately equal overall run times. I use MacTheRipper to rip the DVDs and Handbrake to encode them. My question is, is there a site somewhere that has information regarding which Title track to select? Disclaimer: I cannot stress this enough, I legally own these DVDs. I am merely making a digital copy. Two examples of such DVDs are Star Trek and Carriers. UPDATE: Just an FYI each most of these 99 tracks appear to be the full length tracks. There times look to be very similar to the overall movie run time (within a few seconds of each other). So using the time isn't a valid way to tell which is the correct track. Opening the movie with VLC seems to be the best way to tell. Thank you all.

• Dell fumbles OpenManage installation process, forgets to write documentation?

  - by bwerks

  Hi all, I'm setting up a Dell PowerEdge 2950 for a small business, and I've just spent a while with Dell OpenManage Server Administrator 6.2, trying to clear the installation process of errors before I execute it. Right now I'm getting the following warning from the installer. The installer has detected that the HTTPS listener is not configured for Windows Remote Management. You can either configure the HTTPS listener before installing Remote Enablement, or install Remote Enablement now by selecting the "Custom" installation screen and configure the HTTPS listener later. See the "Remote Enablement Requirements" section in the "Dell OpenManage Installation and Security User's Guide" for information on configuring the HTTPS listener. Note: Remote Enablement is required to manage this system from a remote Server Administrator Web Server and is applicable only for those systems that support Server Instrumentation. Click here to configure HTTPs Listener for Windows Remote Management. The italicized line is a link, which executes...something...via cmd, and doesn't seem to help the problem. Not knowing exactly what to do here, I consulted the documentation. I read through the Setup and Administration section of the User's Guide, but all that it contained was a weird primer on role-based security and some SNMP stuff. The next section skips installation entirely and moved on to features of the suite. Thinking myself crazy, I consulted the readme, which told me that for installation I should consult the "Dell OpenManage Installation and Security Version 6.2 User's Guide" which not only doesn't exist in the documentation, but also not in all of google? Soo yeah, if anyone is familiar with this problem, drop me some knowledge!

• LDAP: Extend database using referral

  - by ecapstone

  My company uses an off-site LDAP server to handle authentication. I'm currently working on a local VPN for my branch that needs to use the off-site LDAP to check user's usernames and passwords, but I don't want every employee to have access to the VPN - I need to be able to control whether users can authenticate with the off-site LDAP based on whether they're allowed to use the VPN. My current solution involves having our own local LDAP server, which has a referral to the off-site server (I got most of my information from here: http://www.zytrax.com/books/ldap/ch7/referrals.html). This means that when local users try to check their credentials with the local server, it redirects them to the off-site server, which checks the credentials. This works for authentication, but not for authorization. It would be easiest to add a vpn_users group or is_vpn_user attribute on the off-site server, but, well, that's above my pay grade. Is there any way I can use the local server to control whether users have access to the VPN without needing to change the off-site server? If I could somehow use it to have a local vpn_users group without the users in it having to be located on the local server, that would probably work, but I have no idea how to set that up or if LDAP even supports such a configuration. For reference, I'm using the openvpn-auth-ldap (https://code.google.com/p/openvpn-auth-ldap/) plugin.

• Cannot find "IIS APPPOOL\{application pool name}" user account in Windows Server 2008

  - by MacGyver

  Normally when setting up IIS 7, I'm used to allowing permissions to user IIS APPPOOL\{application pool name} on the root folder of my web application(s). I also give permissions to IUSR (or the IIS_IUSRS user group. (Note, in Windows Server 2008, I found that IUSR isn't in that group by default, so I added it). In Windows Server 2008, I cannot find user IIS APPPOOL\{application pool name} under Security under the Windows Folder Properties. I'm using Windows Authentication in ASP.NET. I'm receiving a 401.1 on the page in Internet Explorer 8 after getting the authentication prompt. Mozilla Firefox also gave me a Windows authentication prompt, and got me into the site fine. Same with Google Chrome. How can I solve this one? HTTP Error 401.1 - Unauthorized You do not have permission to view this directory or page using the credentials that you supplied.

• User Receiving Partial Downloads

  - by JGB146

  Some background: I run a subscription-based poker strategy video website. Our videos range in length from 30 mins up to 80 mins, and in size from 20MB up to 500MB. The site is on a shared server with hostmonster.com One of my users is having problems downloading some of the larger video file. He reports problems with anything over 100MB. Basically, he's only getting part of the file, which means that the video stops before the end. He has tried multiple computers from multiple locations. He reports that he is able to successfully download 500MB files from other sites. He is using Internet Explorer (version unknown) as his browser. I have suggested that he try Firefox or Chrome to see if their download managers work any better for him, but as of yet I have not heard anything back. He has also reported that his downloads do not report any filesize. I see the same thing (no file size reported), but I have not experienced any problems with the downloads themselves. We pass the downloads through a php script which verifies login information and records the download to our database before returning the file. I suspect this is why there is no filesize reported. What else should I ask the user? What other things could he or I try?

• Monitoring / metric collection for system collectives that change a lot in time (a.k.a. cloud)

  - by Florin Andrei

  When your server fleet doesn't change a lot in time, like when you're using bare-metal hosting, classic monitoring and metric collection solutions (Nagios, Munin) work well. But if the number of systems varies a lot in time, and may in fact vary rapidly, classic software is more difficult to setup and use. E.g., trying to make Nagios (monitoring) keep up with a rapidly evolving cloud infrastructure can be cumbersome. Same for Munin (metric collection). It's not just the configuration, but the way the information is conveyed to the user, or displayed, is inadequate for the cloud. What are some possible alternatives that work well with the cloud? The goals are to collect and display metrics (analog to Munin), and generate alerts when certain metrics go out of bounds or when certain services are unavailable (analog to Nagios), and do everything in a cloud-friendly manner. Some cloud providers offer monitoring / metric collection as services, but not always, and if you use more than one provider you don't want to become too dependent of just one vendor. So provider-independent solutions are required. EDIT: I am asking this question in a general fashion - not limited to any given cloud infrastructure (like OpenStack), but in the general case of using arbitrary cloud providers.

• Font for Wine that supports the entire character set of the Win32 Console?

  - by Brian Campbell

  I would like to be able to display in the Wine console all characters that the Win32 console can display. I've written a small test program to print out all 8-bit characters: #include <stdio.h> int main(int argc, char *argv[]) { int i, j; for (i = 0; i <= 0xF0; i+=0x10) { for (j = i; j <= i + 0x0F; ++j) printf("%2x:%c", j, (char)j); printf("\n"); } getchar(); return 0; } Under Wine, the best I can do so far is using Andale Mono: While this is what I see on Windows Server 2008: Is there anywhere I can legally download a font that will allow me to view all of those characters under Wine? edit I've found a set of DOS fonts that includes a CP437 font, which should cover the character set I'm interested in. However, even if I install this font, wineconsole doesn't seem to recognize it. Is there any way I can get wineconsole to use this font, or convert this font to a format that wineconsole can use? Or is there any way I can extract fonts from DOSEMU for use in Wine? Oh, and I should probably mention that I'm on Mac OS X 10.6.2, installing Wine via MacPorts, using the wine-devel package. more information I have tried installing some console fonts that should cover the full character set as Mac OS X fonts (such as the NewDOS font listed above, and a font I tried converting from the fonts supplied by DOSEMU). Wine does not seem to pick up on new fonts installed in Mac OS X. Is there a way to register new fonts I've installed with Wine? Would manually editing the system.reg file that seems to contain font mappings work, or is there something else I'd need to do? bump Bounty ends soon, I'm still looking for an answer for this. Does anyone use the Wine console for complex text user interfaces?

• [SOLVED] Single Sign On for intranet with Apache and Linux MIT Kerberos

  - by Beerdude26

  EDIT: SOLVED! See my answer below. Greetings, I am looking for a way to do a single sign on to an intranet in the following manner: A Linux user logs on via a graphical frontend (for example, GNOME). He automatically requests a TGT for his username from the MIT Kerberos KDC. Via some way or another, the Apache server (which we'll assume is on the same server as the KDC), is informed that this user has logged in. When the user accesses the intranet, he is automatically granted access to his web applications. I don't think I've seen this kind of functionality while searching the net. I know the following possibilities exist: Using an authentication module such as mod_auth_kerb, a user is presented with a login prompt to enter his username and password, which are then authenticated against the MIT Kerberos server. (I would like this to be automatic.) IIS supports integrated Windows logon via ASP.Net when the user is part of an Active Directory. (I'm looking for the Linux / Apache equivalent.) Any suggestions, criticism and ideas are highly appreciated. This is for a school project to show a proof-of-concept, so every handy piece of information is more than welcome. :)

• Firefox 29 - how do I delete history entries visited fewer than x times

  - by lousyuser

  Context: I've been using my Firefox profile for a couple of years now. My history file has become huge, naturally. I got Firefox Sync set up between my main desktop PC and my laptop. HW configs: PC: i5-3450, 8 GB DDR3 RAM, Crucial M4 128 GB SSD laptop: Pentium SU4100, 4 GB DDR3 RAM, WD 5400 rpm HDD Accessing history entries when typing into the Awesome Bar on my desktop takes quite a long time despite the decent config, the laptop is even slower. The experience is quite unresponsive. I figured if I cleared the history up a little bit, I might avoid creating a new profile to speed things up. The question itself: to illustrate: Is there a way to delete all history entries that have been visited fewer than x (let's say 5) times and at the same time the recent visit is fewer than y (let's say 120) days old? afaik the history file is some kind of SQL database, but I'm not really sure how the data is saved, if there's a "safe way" to edit it and what the query to do what I need would look like. Thanks in advance for any help. I kept browsing through previous SuperUser questions to see if I could find relevant information. "In my Firefox profile directory, there is a filed named places.sqlite. Opening it with sqlite reveals (amongst others) the tables moz_places and moz_historyvisits. It seems that moz_historyvisits uses the primary of moz_places to refer to the URLs." As I'm unfamiliar with databases, I don't really understand the way the two tables mentioned in the quote are related. screenshot of a part of the tables I've noticed the visit_count is in a standard format, making it easy to work with. The last_visit_date looks encrypted to my naked eye, but I can't see in which way. Hope that helps, I'm at my wits' end.

• Selective Pointer device remapping in linux

  - by user6368

  I just got an HP 2710p (hp tablet, with digitizer), and I've played around with linux for a while now, and thought I would go ahead and install it. Everything works fine, excepting normal tablet functions, which is to be expected. I'm working on the screen rotation, and there are on-screen keyboards, etc, but I'm having issues with the stylus. I can tap and left click with the stylus as normal, but the side button (which in windows functions as a right mouse button) appears as a 'button 2' to xev (a middle/scroll wheel button). I can switch 'button 2' and 'button 3' universally using xmodmap, but I'd like to do so exclusively for stylus so I don't screw up regular pointing devices. Altering xorg.conf (which is surprisingly bare) with the recommended sections (adding sections for each of the stylus buttons) does nothing. I'm running crunchbang, which is an ubuntu/debian varient with openbox as the windows manager. Thanks Also, as a seperate note, does anybody know how to detect when I rotate and/or latch the lid shut? I was thinking maybe I could run a script to switch the buttons when I close it, but I can't find any information.

• ATI HDMI Audio disappears in Windows 7 when a TV is connected

  - by jsalonen

  So far I have unsuccessfully googled for HOURS with no luck fixing this very annoying problem. The settings is the following: I have PC running Windows 7 RC (64-bit) Video card is a ATI Radeon 4850 series card (Sapphire HD 4850 512MB to be exact) The video card has HDMI out with built-in audio chip I have an HDMI cable connecting the PC to a TV (Sony Bravia series) The problem is that when I connect the HDMI cable to the TV, the ATI HDMI Sound output device disappears completely from the list of playback devices in Windows. As a workaround I can restore the audio by re-installing the HDMI audio driver. However, when I disconnect the TV the driver disappears again. So basically, every time I want to watch stuff on my TV, I have to reinstall audio driver, which of course is VERY annoying. EDIT: I have figured out that I do not need to re-istall the HDMI audio driver to restore sound; I only need to reboot my computer with the HDMI cable plugged in to restore the audio driver. This suggests that the problem has something to do with information passed from TV to computer, which makes my HDMI Audio driver disappear. Are there any other, more elegant workarounds for this problem? All help is much appreciated!

• How can I safely close this window and forever avoid seeing similar pop-ups from Mackeeper Zeobit's malware and spyware?

  - by Michael Prescott

  The attached image shows a window that just popped up and the only button available is the OK button. I could Force quit Safari, but I've got several sites open right now and don't want to try and find my place again. Besides, I've seen similar hacks in the past and I'd like to learn how to handle them in a way better than just a brute force-quit. I've never heard of MacKeeper or Zeobit, so I opened Firefox and did a few searches while Safari is obviously still stuck, waiting for me to click the sneaky OK button in the dialog window. Anyhow, at least the first few pages of most search results contain lots of blabbering from questionable witnesses about how MacKeeper saved them from some malware or spyware. However, any company that is hacking the browser to maliciously install their product is itself the criminal and not providing a true security application. So, there are three questions here: How can I close this window? Can I do something to Safari to avoid these hacks in the future? (Just curious) Is MacKeeper or Zeobit somehow loading the search results so that no information about their application being malware or spyware is listed (I can't be the only person in the world that is offended by their tactics, even though it appears I am)?

• BTrFS crashhhh?

  - by bumbling fool

  I create a new BTrFS raid10 file system using two 250GB drives and the second partition on a third 80GB drive. I create a subvol and snapshot. I mount the snapshot and start copying 8GB of data to it. It gets to around 1GB and the Desktop disappears and what looks like a non interactive terminal comes up with dump/crash information. I don't have a camera handy or I'd take a picture and post it. It basically looks like stack trace info. CTRL-ALT F7 will eventually bring back the Desktop though but the entire BTrFS portion of the OS is hung and non responsive until I reboot. I've reformated and reproduced this problem 3 times now and I'm about to give up :( I realize it is possible this problem is not entirely BTrFS' fault because I'm on natty which is still alpha. More granular details in case I'm an idiot: 1) Create FS: sudo mkfs.btrfs -m raid10 -d raid10 /dev/sda2 /dev/sdb /dev/sdc 2) Initial temporary mount: mkdir /btrfs && sudo mount -t btrfs /dev/sda2 /btrfs 3) Create subvol btrfs s c /btrfs/vm 4) Create initial snapshot: (optional) btrfs s sn /btrfs/cantremember.snap.something 5)unmount /btrfs and mount /btrfs/vm sudo mount -t btrfs -o subvol=vm /dev/sda2 /btrfs/vm 6) Copy data to subvolume. 7) Balance data across drives: (optional) btrfs f bal <path> (never get to this step 7...) Am I doing something wrong?

• pgpoolAdmin keeps going straight back to it's login page

  - by user705142

  I'm trying to run pgpoolAdmin through nginx - it seems to be working properly, at least initially. I've gone through the initial set-up, which works fine, but now after logging in every link takes me straight back to the login page. It also shows japanese text instead of english, despite picking english in the installation. It seems to me just as if it was unable to save any user data, session information etc. I have javascript/cookies enabled, so it's not that. The ownership of the folder is nginx, and so too is pgmgt.conf.php, so it shouldn't be a problem with permissions. One potential issue is that I can't seem to see any confirmation that php postgresql support is enabled in the php info screen, despite the correct package installed and in the config line. Any ideas as to what's happening here? The nginx rules are pretty standard: server { # pg-pool admin listen 997; server_name localhost; root /opt/pgpooladmin; index index.php; location ~ .php$ { fastcgi_pass_header Set-Cookie; fastcgi_pass 127.0.0.1:9000; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_index index.php; include fastcgi_params; } }

• How do you setup FTP with IIS Manager Users in an NLB environment with shared IIS configs?

  - by William Jens

  I've setup a 2 node NLB cluster and used the following to share IIS configs between them. http://blogs.technet.com/b/meamcs/archive/2012/05/30/configuring-iis-7-5-shared-configuration.aspx The IIS configs and content is located on a network share via a UNC path. This works - updating IIS settings on one node, is visible in another node and my website works on the individual nodes and the cluster as whole. I'm able to setup an FTP site and successfully connect with my Windows login. However, I want to use IIS Manager Authentication as defined in: http://www.iis.net/learn/publish/using-the-ftp-service/configure-ftp-with-iis-manager-authentication-in-iis-7 I've tried using "Network Service" with the FTP COM object as well as a dedicated user account that exists on all three hosts, but every time I try to login with an IIS user I get something like the following: IISWMSVC_AUTHENTICATION_UNABLE_TO_READ_CONFIG An unexpected error occurred while retrieving the authentication information. Exception:System.Runtime.InteropServices.COMException (0x8007052E): Filename: Error: at Microsoft.Web.Administration.Interop.AppHostWritableAdminManager.GetAdminSection(String bstrSectionName, String bstrSectionPath) at Microsoft.Web.Administration.Configuration.GetSectionInternal(ConfigurationSection section, String sectionPath, String locationPath) at Microsoft.Web.Management.Server.ConfigurationAuthenticationProvider.GetSection(ServerManager serverManager) Process:dllhost User=NT AUTHORITY\NETWORK SERVICE Can anyone point me in the right direction here?

• Shadow copy referencing invalid volume from symboliclink

  - by ccook

  I recently replaced my motherboard after the last one failed (was shorting and causing random reboots). I'm sure this was not healthy for the machine, and that a clean install would do wonders, but I'd like to fix the current install. That aside, I've been tracking down a pair of errors in the application log. Volume Shadow Copy Service error: Error calling a routine on a Shadow Copy Provider {b5946137-7b9f-4925-af80-51abd60b20d5}.

• How can I run Gnome or KDE locally in Cygwin?

  - by John Peter Thompson Garcés

  Apparently it is possible to do this using cygwin ports, as can be seen in screenshots. I followed this how-to to get apt-cygports set up, and I used it to install gnome-session. This how-to supposedly gives the commands needed to run Gnome or KDE, but whenever I try to run Gnome, a blank X-window pops up and then quickly disappears. Here is the terminal output: $ startx /usr/bin/dbus-launch gnome-session xauth: file /home/jpthomps/.serverauth.4168 does not exist Welcome to the XWin X Server Vendor: The Cygwin/X Project Release: 1.10.3.0 OS: Windows 7 Service Pack 1 [Windows NT 6.1 build 7601] (WoW64) Package: version 1.10.3-12 built 2011-08-22 XWin was started with the following command line: /usr/bin/X :0 -auth /home/jpthomps/.serverauth.4168 (II) xorg.conf is not supported (II) See http://x.cygwin.com/docs/faq/cygwin-x-faq.html for more information LoadPreferences: /home/jpthomps/.XWinrc not found LoadPreferences: Loading /etc/X11/system.XWinrc LoadPreferences: Done parsing the configuration file... winDetectSupportedEngines - DirectDraw installed, allowing ShadowDD winDetectSupportedEngines - Windows NT, allowing PrimaryDD winDetectSupportedEngines - DirectDraw4 installed, allowing ShadowDDNL winDetectSupportedEngines - Returning, supported engines 0000001f winSetEngine - Using Shadow DirectDraw NonLocking winScreenInit - Using Windows display depth of 32 bits per pixel winFinishScreenInitFB - Masks: 00ff0000 0000ff00 000000ff Screen 0 added at virtual desktop coordinate (0,0).

• Loop through several servers, find specific dlls , get the dll version, internal filename and path?

  - by Graham

  I am a newby to Powershell, and using PS v2. I can see the massive potential it has, but I just can't get the following code to work fully. I am trying to end up with a csv file that contains the wild carded required dlls in the GAC_MSIL or sub-directory, get the dll version, internal filename and path, and the server IP address. The code is below, and it is in single line format because it appears easier to remote onto one of the servers in the server farm and run the single line from that console, ue to security log-ins etc. The code has produced a set of results, but only for the last server, it probably does the first server, then overwrites it but I am not sure about that. I have done a lot of reading about using arrays, and custom objects, and had a go at doing that, but my scripting skills in PS are not yet up to it. Code: $out = "Ouput_dll_ver_results.csv";foreach ($server in '11.222.33.123', '11.222.33.124') {$VersionInfo = (Get-ChildItem \$server\C$\windows\assembly\GAC_MSIL -recurse -Include abc*.dll,def*.dll,ghi*.dll,jkl*.dll | Where-Object { $.FullName -notmatch "\windows\assembly\temp\" })}; $VersionInfo | %{Get-Command $.FullName} | select -expand File* |Export-Csv $out Can you please advise if/how the above code can be corrected, and if not, what alternatives do I have to get the information I need. Many thanks in advance. Graham

• How should I monitor memory usage/performance in SunOS/Solaris?

  - by exhuma

  Last week we decided to add some SunOS (uname -a = SunOS bbs-sam-belair 5.10 Generic_127128-11 i86pc i386 i86pc) machines into our running munin instance. First off, the machines are pre-configured appliances, so, I want to avoid touching the system too much without supervision of the service provider. But adding it to munin was fairly easy by writing a small socket-service (if anyone is interested, I put it up on github: https://github.com/munin-monitoring/contrib/tree/master/tools/pypmmn) Yesterday, I implemented/adapted the required plugins for our machines. And here the questions start: First, I have not found a way to determine detailed memory usage values. I get the total memory by running prtconf | grep Memory, and the free memory using vmstat. Fiddling together a munin-plugin, gives me the following graph: This is pretty much uninformative. Compare this to the default plugin for linux nodes which has a lot more detail: Most importantly, this shows me how much memory is actually used by applications. So, first question: Is it possible to get detailed memory information on SunOS with the default system tools (i.e. not using top)? Onto the next puzzle: Seeing the graphs, I noticed activity in the "Paging in/out" graphs, even though the memory graph still has unused memory: Upon further investigation, I found out that df reports that /tmp is mounted on swap. Drilling around on the web, I understood that df will display swap, but in fact, it's mounted as a tmpfs. Now I don't know if this explains the swap activity. The default munin-plugin for solaris uses kstat -p -c misc -m cpu_stat to get these values. I find it already strange that this is using the cpu_stat module. So maybe I simply misinterpret the "paging" graphs? Second question: Do the paging graphs indicate that parts of the memory are paged to disk? Or is the activity caused by file operations in /tmp?
