• Which version control should I use for my configuration files?

  - by rakete

  I want to store some of my configuration files (~/.emacs.d/, .Xdefaults, etc. linux $HOME stuff) in version control so I can easily sync them with my notebook/workplace and see my past changes and revert to them should the need arise. So far it seems to me that there are quite some people using git for this and I think that I too want to use a distributed vcs for this (if only to get more used to them) but I can't say that I am very experienced with all things dvcs. I did use darcs and git briefly and so far I can say that I really like the way git handles branches, and I think the possibility to have different branches within the same directory is especially useful for my use case. Darcs on the other hand has cherry picking of patches, which too is quite the convenient feature when managing configuration files (at least I assume it is). So, what would you recommend to use? And what would be your reasoning for your recommendation? What other vcs with nice feature that I haven't mentioned exist and would make a good vcs to store configuration files and why?

• Install and enforce a scheduled task across a Windows domain

  - by Ricket

  We have a small domain of about 70 Windows computers (XP and 7). We want to schedule a command (an update mechanism) to run on all computers periodically, and we want the task to run regardless of the computer's connection to our network (i.e. the task should run even on a laptop that isn't connected to our VPN). We have a Microsoft System Center Essentials 2010 server so that might come in handy. The options I see are these: Do it completely manually. Install the scheduled task by hand or remotely using psexec (and the at command?) for each computer in our network. Enforce that newly imaged computers should have this task installed on them before deployed to the employee, or the task should be in the image. High initial cost (having to do this for each of 70 computers) but building it into the image might work... But there is some maintenance in making sure the task is added to everything. And I fear that a year or two down the road, we will have forgotten about it or gotten sloppy or had new IT employees who miss this step and some computers won't have the task. Having one of our servers run a script that loops through all computers and psexec's the command on each computer in the network -- it would only run on running, connected computers, so this solution wouldn't work. I suspect SCE could do something like this too, but again this is not a good solution. Neither of these are ideal, and I'm certain there is a better way to do it -- right? What is the best way to accomplish this task?

• Home network with two isolated separate subnets, running on cablemodem/router and WRT-router.

  - by Johan Allgoth

  I have a new connection with a nice new router/cable-modem. I'd like to setup it up optimally and needs some pointers. I am a complete n00b when it comes to routing. I want to end up with two separate subnets, 10.1.2.0/24 and 192.168.1.0/24 each available on their own wireless channel/SSID. Both firewalled. I want my wired computers on the gigabit switch, optimally with public ips. I want to be able to reach 192.168.1.0/24 from 10.1.2.0/24, but not vice versa. Everyone should have internet access. Hardware and capabilities: Netgear CG3100. Handles cable connection. Gigabit switch. 802.11n. Can do DHCP, firewall, NAT etc. Can choose subnet. Can turn of NAT and if so hand out up to 4 public ips. Somewhat challenged when it comes to configuration. WRT-router. Runs DD/Open-WRT very stable. 100 Mbit switch. 802.11.g Can do DHCP, firewall, NAT etc. Can choose subnet. Highly configurable. I hope to be able to keep 10.1.2.0/24 on the CG3100, for speed reasons and 192.168.0.0/24 on the WRT-router for quota and user control reasons. On my 10.1.2.0/24 network I plan on running servers for various services. Should I turn of NAT on the WRT-router? Or on the cable modem? Activate what in that case? Is double NAT always f-ed up?

• Debian, How to convert filesystem from ISO-8859-1 into UTF-8?

  - by Johan

  I have a old pc that is running Debian stable, that is in need of a upgrade. The problem is that it is using latin1 (ISO-8859-1) for everything, and since the rest of the world has moved to UTF-8 I plan to convert this computer as well. And for this question I will focus in on the files that are served with Samba, and some has some latin1 characters in the filenames (like åäö). Now my plan is to move all data of this old computer onto and a brand new one that is running Debian stable (but with UTF-8). Does anybody have a good idea? Thanks Johan Note: later I plan to use iconv to convert the content of some files with something like this: iconv --from-code=ISO-8859-1 --to-code=UTF-8 iso.txt > utf.txt However I don't know of a good way to convert the filesystem it self. Note: Normally I usaly just scp from one computer to the next, but then I end up with latin1 characters in the utf-8 filesystem... Update: Did a small test round with a hand full of files (with funny chars) in the filenames, and that seemed like it could work. convmv -r -f ISO-8859-1 -t UTF-8 * So it was only to execute with the --notest convmv -r -f ISO-8859-1 -t UTF-8 --notest * Nothing more to it.

• unreadable corrupted ntfs partition - lost clusters reported

  - by Eduardo Martinez

  Hi, partition magic is reporting multiple 'bad file record signature' and 'lost clusters' errors on my 250GB samsung sata disk (connected via usb on a xp sp3). Unfortunately PM is unable to fix. PM shows the drive as being NTFS, detects used space ok and also drive name. But PM browser (right click on partition, browse...) won't show anything (as if disk was empty) Windows Explorer is not even picking the drive name and reports 'the file or directory is corrupted and unreadable' PTDD partition table doctor demo tells me the boot sector is fine, and I can see all disk content on its browser - but crucially cannot copy that content over to a new disk (PTDD browser is pretty arid to say the least) Also tried - photorec-6.11.3 - it actually started to extract files but wouldn't keep file names or any folder structure (maybe I missed sth on the configuration options) - find and mount - intellectual scan went well, the only partition on the disk was detected, then tried to mount into p: but got this error on windows explorer: 'p:\ is not accesible. The media is write protected'. Find and mount allows you to create an image from partition but I don't have a disk big enough at hand. Does anyone know if this will keep the extracted files/folders structure intact? I'm starting to think the disk is pretty screwed and my chances to recover this data are slim. Please someone enlighten me with that marvellous piece of software I am missing :-) Thanks in advance

• FTP FileWatcher

  - by Meiscooldude

  So, I am in this little predicament where I am stuck watching a few ftp folders to see if they have new files added to them. If they do, it needs to throw an event with the file name. Thereby telling something else to download that file. This is a pretty simple object to make, I was just curious if anyone knew how expensive this operation would be? I plan on using the command NLIST because I don't need file size information, and there will be no sub-directories in the folder. Each file in the folder will have exactly 25 characters in its name. There could be anywhere from 10 to 'maybe' a couple thousand (max around 2000) files per folder (usually on the lower end, 100-300, but currently growing). The files are anywhere from 250kb to a very VERY unlikely 10mb (usually within the 250kb to 4mb range). There possibly could be up to a few hundred folders (in which case I could change the watch frequency depending on number of folders), but currently there are only a few (6-10ish). There also would be multiple logins for the ftp server, different logins would have access to different folders. I am not asking for an implementation, just if anyone has some first or second hand knowledge about FTP, how could this affect my network. I am not opposed to putting in file retention times or change the frequency in which I check for new files.

• Nginx : Proper use of limit_req_zone and limit_req

  - by xperator

  I have 2 website running on VPS. Their purpose is sharing music files and publishing news. Both of them use wordpress. What I am trying is that I want to prevent little hackers from flooding the webserver and putting stress on the server to make it crash. The problem is that after using limit_req_zone and limit_req my website became very slow. Browsing Wordpress control panel takes a long long time. I tried changing values but it didn't improve much. I guess the problem is Wordpress because it's the only script I am using on both front and back end. Here is the last setting which seems to be more responsive than others : limit_req_zone $binary_remote_addr zone=flood:5m rate=10r/m; location ~ \.php$ { limit_req zone=flood burst=100 nodelay; } What are the optimal values that should be used in my case (wp) ? I want the website have it's normal behavior, On the other hand stopping lifeless people from flooding. Another question, Is it safe and enough to use limit_req only on php files ?

• Copy past speed very slow for a large number of tiny files on Windows but not on linux

  - by Arno2501

  I've got this folder which contains 15'000 of tiny images (around 400 bytes each). If I copy past this folder on my laptop (Windows 7, i7 latest gen, superfast ssd) it takes about 30 seconds (yes for 7 megs !!!) the average transfer rate is 400 KBytes / second which is so slow. I mean my usual transfer rate is more like hundreds of MBytes per second !!! I get the same problem on my servers (Windows 2003, 2008 /r2) and on every Windows box that I could get my hands on. On the other hand if I do the same on a linux box (debian base, Ext3 FS) (which runs on the same SAN than all the windows servers I've tested) It's nearly instantaneous !!! I'm pretty sure the size / number of the files may stress such filesystem more than another but such differences !? Why is that ? Why is it so slow on the windows boxes (more that 30 sec for 7 MB) and so fast on the linux ones (one sec or so) (I mean this was not a hardlink that I've created it was a true copy). Is it a normal behaviour or something unusual ?

• Prevent SSL certificate being returned for a specific domain

  - by jezmck

  Apologies for a long question: We've taken on a new client whose web hosting was previously on their in-house server which still has their Exchange/Outlook email. We now host their domain (and many others) on our server. They're complaining that they're getting errors in Outlook. I don't understand the AutoDiscover stuff at the root of the problem, but believe that I just need to stop the SSL certificate on our server being returned when requested at a particular domain: Yes it is, the issue lies with "{newclient}.com" being pointed to your server IP and that server has Port 443 open with an SSL certificate associated to it. So when Outlook/ActiveSync use autodiscover to find the mailbox settings it find your SSL (because 443 is open) and flags it as an error. The solution is to close 443 so its not discovered, Autodiscover will then proceed to mail.{newclient}.com via the MX / ServiceRecords and discover the correct SSL. I'm new here and there was no hand-over, so I don't know whether other currently hosted sites need to accept SSL connections, though I suspect some will, or may in future. This is a live server, so I can't risk trying loads of options in case I take the server offline! I feel like I should be adding something like the following to vhosts.conf. <VirtualHost *:443> ServerName {newclient}.com ServerAlias www.{newclient}.com SSLEngine Off SSLCertificateFile {NONE} SSLCertificateKeyFile {NONE} </VirtualHost> Apologies for the fact that I don't know enough about this subject to be able to ask the question more clearly!

• Powershell script to delete secondary SMTP addresses of Exchange 2010 Mail Contacts

  I have a few thousand Exchange 2010 Mail Contacts who get erroneously assigned internal SMTP addresses by the default recipient policy.

• How many reverse proxies (nginx, haproxy) is too many?

  - by Alysum

  I'm setting up a HA (high availability) cluster using nginx, haproxy & apache. I've been reading great things about nginx and haproxy. People tend to choose one or the other but I like both. Haproxy is more flexible for load balancing than nginx's simple round robin (even with the upstream-fair patch). But I'd like to keep nginx for redirecting non-https to https among other things right at the point of entry to the cluster. On the other hand, nginx is a lot faster for serving static contents and would reduce the load on the powerful apache which loves to eat a lot of RAM! Here is my planned setup: Load balancer: nginx listens on port 80/443 and proxy_forwards to haproxy on 8080 on the same server to load balance between the multiple nodes. Nodes: nginx on the node listens to requests coming from haproxy on 8080, if the content is static, serve it. But if it's a backend script (in my case PHP), proxy forward to apache2 on the same node server listenning on a different port number. Technically this setup works but my concerns are whether having the requests going through several proxies is going to slow down requests? Most of the requests will be PHP requests as the backends are services (which means groing from nginx - haproxy - nginx - apache). Thoughts? Cheers

• What is a good WordPress theme for long Objective-C code samples [closed]

  - by willc2

  As some of you iPhone developers know, Objective-C can be a verbose language. Long, descriptive variable and method names are the norm. I'm not complaining, it makes code easier to read and code completion makes it easy to type. But damn! Check out this method name for getting a cell in a table view: -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath; I have a WordPress blog where I publish my code samples as I'm learning the language. One thing I hate on other blogs is how the code won't fit in a column without that scroll bar or without wrapping around. It really made it hard for me to read and comprehend method names back when I was a super-noob (six months ago). Right now I use the clean-looking Fazyvo 1.0 theme by noonnoo. I love the look of it but the columns are just too narrow and it doesn't have support for wider ones. I could hand-modify it but then I'd have to maintain/redo those changes every time I updated it. Instead, I'm looking for a nice theme that has width control built-in and looks good at larger font sizes. Can anyone help? Note: I use WP-CodeBox for code syntax highlighting.

• TCP Server Memory management: #Connections Vs. #Requests

  - by Andrew

  Given that, there is no theoretical limit to number of concurrent TCP connections a Windows 2008 server can handle. Only thing will happen is, with each connection there will be memory consumption in server. Unfortunately, memory is not unlimited (and I want to utilize only physical memory). For example, lets say we've 2GB server memory. Now there are two extreme cases: Case 1: If we've allocated 64KB buffer for each connection (only to receive incoming request), then 32768 connections can consume all the 2GB of memory. This will not leave any memory to queue/process incoming requests from those connections. Case 2: On the other hand, lets say a single (or very few) connections continuously keeps sending request buffers (for example, video streaming from one connection to other) and server cannot process them within time, those buffers will get piled up in server and eventually will occupy most of the servers memory. And it will not leave any memory for new connection thereafter. This is the real dilemma in server design bugging me badly for last many days. If I can decide on max size of request buffer per connection and max number of requests to allow in queue per connection. Then, based on available server memory, it will then automatically set limit on max number of concurrent connections. How to decide on these limits to achieve best performance and throughput? I am just looking for perfect utilization of server resources. Are there any standard guidelines or empirical data available with someone who can share with me please.

• chrooted sftp user with write permissions to /var/www

  - by matthew

  I am getting confused about this setup that I am trying to deploy. I hope someone of you folks can lend me a hand: much much appreciated. Background info Server is Debian 6.0, ext3, with Apache2/SSL and Nginx at the front as reverse proxy. I need to provide sftp access to the Apache root directory (/var/www), making sure that the sftp user is chrooted to that path with RWX permissions. All this without modifying any default permission in /var/www. drwxr-xr-x 9 root root 4096 Nov 4 22:46 www Inside /var/www -rw-r----- 1 www-data www-data 177 Mar 11 2012 file1 drwxr-x--- 6 www-data www-data 4096 Sep 10 2012 dir1 drwxr-xr-x 7 www-data www-data 4096 Sep 28 2012 dir2 -rw------- 1 root root 19 Apr 6 2012 file2 -rw------- 1 root root 3548528 Sep 28 2012 file3 drwxr-x--- 6 www-data www-data 4096 Aug 22 00:11 dir3 drwxr-x--- 5 www-data www-data 4096 Jul 15 2012 dir4 drwxr-x--- 2 www-data www-data 536576 Nov 24 2012 dir5 drwxr-x--- 2 www-data www-data 4096 Nov 5 00:00 dir6 drwxr-x--- 2 www-data www-data 4096 Nov 4 13:24 dir7 What I have tried created a new group secureftp created a new sftp user, joined to secureftp and www-data groups also with nologin shell.

Sftp user is in the www-data group but permissions in /var/www are read/read+x for the group bit so... It doesn't work. I've also tried with ACL, but as I apply ACL RWX permissions for the sftp user to /var/www (dirs and files recursively), it will change the unix permissions as well which is what I don't want. What can I do here? I was thinking I could enable the user www-data to login as sftp, so that it'll be able to modify files/dirs that www-data owns in /var/www. But for some reason I think this would be a stupid move securitywise.

• What are some of the best answer file settings for a WDS Deployment?

  - by drpcken

  I've had my head buried in answer files for days now and have gotten quite comfortable setting them up, test, etc... I use a handful of Components to help my migrations, for my unattend.xml I like: Windows-International-Core-WinPE -- this is good for setting Locales the preboot environment (en-us for us english US speakers). Keeps me from having to set these on the initial image boot. Windows-Setup_neutral -- I like the WindowsDeploymentServices -> ImageSelection, especially if I'm only pushing a single image. This keeps me from having to select it each time. My OOBE_Unattend.xml is really useful and I barely have to touch anything during this part of the installation: Windows-Shell-Setup_neutral -- This lets me put a ProductKey in for my MAK volume license (very useful and time saving). I can also set the TimeZone for the installation. Windows UnattendedJoin_neutral -- I couldn't live without this component. It joins the machine on my domain before logging in as a domain administrator. I would hate to not have this ability. Windows-International-Core -- Again this component really speeds up the OOBE process. I configure my locals and time zone so I don't have to do it by hand when the machine enteres OOBE. Windows-Shell-Setup -- Allows you to configure an autologon when the new machine is finished. I like to logon as a domain admin automatically for customizing and troubleshooting the new machine immediately after it is imaged. Also the OOBE component under here lets me skip the EULA, Hide Wireless Setup, and set my default NetworkLocation. All of this makes the entire OOBE totally automated. What are some other good components I am missing as far as helping me get these images pushed and configured as quickly as possible?

• What is the 'best practice' for installing perl modules on Solaris/OpenSolaris?

  - by AndrewR

  I'm currently in the process of writing setup instructions for some software I've written that is implemented as a set of Perl modules. Having done this for various flavours of Linux, I'm now doing the same for Solaris/OpenSolaris (v10 only). Part of the setup process is to make sure that dependent Perl modules are installed. This has been pretty easy on Linux as the Perl modules I require tend to be within the distro's packaging system (eg yum install perl-Cache-Cache). This is not the case on Solaris so I'm working on setup instructions that use the CPAN module to fetch dependent modules (eg perl -MCPAN -e 'install Cache::Cache'). This works ok but there are known problems with modules that require things to be built with a C compiler. The problem is that the C Makefile generated assumes you're using Sun's compiler and uses command-line options not understood by gcc, which you may be using instead. Consulting teh Internetz has thrown up a number of solutions to this: Install and use Sun's compiler Use the perlgcc wrapper script Edit the makefiles by hand (yuk) All of these work. My question to those more familiar with Solaris than me is: Is one of these the 'best' or 'most commonly used' method?

• Weird PCI bug: lots of missed packets, or data comes in "bursts"

  - by Thomas O

  I have an ABIT KN9 motherboard. It has one PCI-e x16 slot, three PCI-e x4 slots and two legacy PCI. My problem is with the legacy PCI (which I shall just call "PCI".) I currently have an Nvidia GeForce 8600 GT (a low end card) installed in the x16 slot and a TV card in PCI #1; the x4 slots are unused, as is PCI #2. I plan to upgrade the graphics card soon, the current card was spare. I sometimes install a USB expander in PCI #2 but it causes a lot of problems - see below. The problem is under Linux (Ubuntu 10.10, Linux 2.6.35-22-generic), but probably under all operating systems (I have not yet been able to test Windows, but I suspect it will do the same as the problems occur on the BIOS/POST side too, e.g. when using a USB keyboard on the expander the keyboard will not work at all) PCI has an enourmous delay, and packets arrive in large chunks. For example, when using the USB expander, my USB mouse lags and jumps in large steps every second or so, while using the motherboard USB does not present this problem. My TV card will only do one or two frames per second, and the program (xawtv) usually times out and crashes. In dmesg, I'm getting messages like: bttv0: timeout: drop=74, irq=154/100476, risc=31f6256c, bits: VSYNC HSYNC OFLOW RISCI for my TV card, and similar timeout issues for my USB expander with a mouse. I received the motherboard, processor and RAM second hand and have only just got around to building it, so I don't know if this problem has always existed, or if it's a result of my set up. If anyone has any hints or solutions it would be appreciated - this is kind of a show-stopper for me.

• How to implement a virtual server running Ubuntu inside a fileserver in windows?

  - by user541445

  I work in a company that has some limitations regarding their budget. They need client/server aplication. I can code the aplication, I've made mini tests on primordial applications that work. The thing is that they only have fileservers, and the application they need must be concurrent compliant, so the database must be in their local network (Fileserver is the only choice). So far, I have explored almost any option available, starting with: Desktop databases. Access (We have a license)(But concurreny is just not effective, besides it's a windows software, yuck). Sqlite (Nice, but since the information they manage is a lot, I've performed some concurrency tests with INSERTs and doing SELECTS at the same time). It fails, somehow it just stops inserting. Open office Base (I dismember a base office only to see that it was a file mode HSQLDB). I've tried, not concurrent at all. Etc (You name the Open source Desktop Database manager, and yes, I've tried that one.) Server databases Call me a stubborn person, but reading some server databases documentation say that their databases will work in a file mode. I've tried a lot of products. Postgres, MySQL, FireBird, H2, Derby, Oracle Express, IBM DB2 Express, etc. So, I really need a hand here, I've been doing this install/delete/depression thing with a lot of databases for 3 weeks, until I got with a crazy idea and I just came here to express it. So, my question comes down to this: Installing a light virtual OS software like Virtual PC and then installing in there a Server OS like an Ubuntu server inside that virtual software will work? Will it work 24/7 or when I close the virtual pc software? Will this work in a fileserver? Any suggestion, answer, critic to the place I work, crazy new concurrent database that will work in fileserver will be most than welcome.

• How can I get Windows 8 to automatically disable touch when I am using my Wacom pen and turn it back on when I am not

  - by Robert

  I have an HP convertible tablet computer which I just upgraded to Windows 8. The problem (which existed under Windows 7 as well) is that this tablet has both a capacitive touch screen (with multi-touch) AND a wacom-type tablet built in to the screen that works using electro-magnetic resonance with the provided stylus. My Use Case: Most of the time I am happy using my fingers and the touch interface for navigation and whatnot. However, when I want to get down to serious note-taking/drawing, I want to use the wacom functionality. The problem is that any comfortable writing position has me resting my arm/hand on the screen, which activates the touch technology (despite supposed palm-detection algorithms) and completely screws up my input paradigm. My Ideal Solution: Ideallly, since wacom technology senses when the pen is "close" to the screen, I would love to have touch be automatically disabled whenever the wacom pen is detected, and turned back on when it is out of range. this would allow me to seamless switch between the two input methods, and since I NEVER want to use both at once would work perfectly for me. An acceptable alternative: As a next best option, It would be great to be able to turn off the touch functionality (leaving the wacom in place) whenever I entered specific apps (e.g. OneNote, Photoshop, Gimp, Pencil, etc.) and then have it turn back on when I left that app.... As a worst case at least lets me use my PC option: If I could create a shortcut (tile or otherwise) that flips the touch on and off without going all the way through the nested computer settings, that would be better than nothing. Thanks in advance for the help with 1 or more of the above.

• Migrating Linux user data to Windows profiles automatically

  - by scott ryan

  I have what seems to be an incredibly simple problem with a very simple solution but I'm having some trouble connecting dots. I have an aging server running Ubuntu Server which hosts roaming profiles. I am switching to a Windows Server 2012 DS shortly. Users used to be named firstinitial.lastname and we are switching to firstname.lastname. I need to transfer things like favorites, documents, etc. from the roaming Linux profile to the user's local Windows profile. So, the way I think it'd work is by using a login script. I think I'd use a script to mount the Linux server's /home for each user, then do copy to various paths (documents, pictures, etc.). But, how do I automate this for each user that logs in? I'm working with a nonprofit, so doing this by hand would probably be out of their budget. I'm open to suggestions, though. What I want is basically Windows Easy Migration, but I'm fairly certain that won't work under Wine... (Kidding, I promise). Thanks!

• Is there a good alternative to Videora iPod Converter?

  - by Richard

  I use Videora to convert my videos (in DivX/XviD format) to something I can play on my iPod Classic. I really dislike it. It's clunky, riddled with adverts, sometimes doesn't convert properly (the infamous "invalid public atom" error - see Google for more) and has a UI that truly stinks. On the upside, it's free, accepts a list of video files (via the oddly hard to find "1-click convert" button) and just gets on with the converting as it already knows the correct settings for my iPod. One final nice touch is that once they are converted, it'll automatically upload them into iTunes. Are there any alternatives which have all the upsides but none of the downsides? Bonus points if they can set the metadata in iTunes correctly for TV shows (season, show, episode) and delete the converted file afterwards (as my iTunes settings means that a copy is made elsewhere). I've looked at a bunch of applications (handbrake, virtualdub, mediacoder, format factory, any video converter, convertxtodvd) but many of them fail the "just select a list of files and get on with converting" test - let alone all the other features I want. I have no desire to individually set the video size of each file or the codec or the post-processing options. I'm currently using the command line version of HandBrake (handbrakecli) and a hand-written DOS batch file to go through every file in a folder and convert it. It does most of what I want, just not in a very slick way. Can anyone recommend anything better? It needs to work on Windows 7 and be free.

• Remote mouse pointer not visible in VNC

  - by aef

  I used VNC desktops as a kind of collaboration server, as shared planning and pair programming environment for a long time. Now my latest iteration uses a KVM guest running Fedora 17 "Beefy Miracle", the Cinnamon desktop environment and an X11VNC server. The X11VNC server is automatically started with the desktop environment using the following command: x11vnc -localhost -many -shared -display :0 -bg My problem is that depending on the VNC client, the mouse pointer of the remote system which is shown through VNC is not synchronized to my client. I really need this, so I can see what my partner is doing on the desktop. When using Vinagre 3.2.1 on Ubuntu Oneiric Ocelot (11.10) or Vinagre 2.3.0.3 on Debian Squeeze (6.0) and I don't have my local mouse pointer inside the VNC view, I cannot see the mouse pointer of my remote system, nor its movement. When using TightVNC on Windows 7, I can recognize a mouse pointer trace for very short amounts of time after moving the mouse, but it is not clearly visible. Using UltraVNC on Windows 7 the mouse pointer is clearly visible all the time. With Gnome 2 I never had any problems with remote pointer synchronization, using exactly the same clients. I suspect this could have something to do with Cinnamon's dependency on 3D acceleration. On the other hand, it doesn't change anything to start Cinnamon's fallback environment Cinnamon 2D. Update: Same effect when I use Gnome 3.

• Boot sequence unlike reboot

  - by samgoody

  When I turn on the computer it acts very differently than when I reboot it. [WinXP Pro, Intel Core2 6600, 2.4GHZ, 2GB RAM, NVIDA GeForce] Boot: Monitor must be plugged into the motherboard or no image. Screen resolution 800x600. Changes to the resolution cause only the top half of the screen to be usable, and are lost when I shut down the computer. Desktop icons arranged in neat rows on left of desktop. Nothing of note in system tray In Device Manger - Display adapter: Intel(R) Q965/Q963 Express Chipset Family In Device Manger - Monitors, two monitors are listed Hibernate and standby work. Reboot: Monitor must be plugged into the graphics card or no image. Screen resolution - 1280x1024 Desktop icons arranged in the cute circle that I put them in. NVIDIA icon shows in system tray. In Device Manger - Display adapter: NVIDA GeForce 6200LE In Device Manger - Monitors, one monitor is listed Hibernate and standby do not work. When awakened after a hibernation it says: The system could not be restarted from its previous location because the restoration image is corrupt. Delete restoration data & proceed to system boot? Double reboot (inconsistent): Monitor must be plugged into the graphics card. Screen resolution - 1024x768 Odd icon shows in system tray whose tooltip says "Intel Graphics" For a while my morning ritual was to boot, wait, reboot using (alt+ctrl+del - ctrl+u - R), wait. Keeping the monitor plugged into the graphics card. But aside for the inefficiency of this method, I sometimes want to standby and can't. On the other hand, the computer is unusable when set to 800x600. Please help, anyone?

• TC hashing filters - single rule deletion

  - by exa

  For traffic shaping I'm currently using a setup that looks exactly like the setup from LARTC, on this page: http://lartc.org/howto/lartc.adv-filter.hashing.html I have a simple problem with that - everytime I want to modify something in the hash table (like assign a IP to different flowid), I need to delete the whole filter table and add it again filter by filter. (I actually don't do it by hand, I have a nice program that does it for me... but still...) There is a problem - I got roughly 10k filters allocated this way and deleting and refilling the whole filtertable can get pretty lengthy, which is not exactly good for traffic shaping. My program could easily manage to delete only the rules that need to be deleted (thus reducing the whole problem to several commands and miliseconds), but I simply don't know the command that deletes only the one hashing rule. My tc filter show: filter parent 1: protocol ip pref 1 u32 filter parent 1: protocol ip pref 1 u32 fh 2: ht divisor 256 filter parent 1: protocol ip pref 1 u32 fh 2:a:800 order 2048 key ht 2 bkt a flowid 1:101 match 0a0a0a0a/ffffffff at 16 filter parent 1: protocol ip pref 1 u32 fh 2:c:800 order 2048 key ht 2 bkt c flowid 1:102 match 0a0a0a0c/ffffffff at 16 filter parent 1: protocol ip pref 1 u32 fh 800: ht divisor 1 filter parent 1: protocol ip pref 1 u32 fh 800::800 order 2048 key ht 800 bkt 0 link 2: match 00000000/00000000 at 16 hash mask 000000ff at 16 The wish: 'tc filter del ...' command that removes only one specific filter (for example the 0a0a0a0a IP match (IP address 10.10.10.10)). Removal of some small subgroup would also be good - for example I could still recreate a bucket (bkt a) pretty fast. My attempts: I tried to number all the filters using prio, but with no help -- they just create something unusuable (but deletable) below, but the bucketed filters remain there after that gets deleted. Any ideas? edit - I'm adding a simplified tl;dr description of the problem: I created hash filter on some interfce just like in this http://lartc.org/howto/lartc.adv-filter.hashing.html I want to find a command that deletes one rule (e.g. 1.2.1.123) from the table, leaving the rest untouched and working.
