• Almost every Inkscape extension yields an error in Mac OS X

  - by andyvn22

  I've run the latest few versions of Inkscape (currently landed on "0.47+devel"), and have been having trouble with the Extensions menu. So far, in every version of Inkscape I've tried, nearly every extension yields the following error: The fantastic lxml wrapper for libxml2 is required by inkex.py and therefore this extension. Please download and install the latest version from http://cheeseshop.python.org/pypi/lxml/, or install it through your package manager by a command like: sudo apt-get install python-lxml I've tried the instructions listed there, of course, with no effect. I've also found many references to this issue on fora, in bug trackers, etc., and as such also tried: sudo easy_install lxml cd /Applications/Inkscape.app/Contents/Resources/lib mv libxml2.2.dylib libxml2.2.dylib.old ln -s /usr/lib/libxml2.dylib and a few similar solutions. Nothing has produced any change in Inkscape's behavior. Does anyone know A) what's really going on here? Because from what I gather the error is not describing the actual problem. And of course B) a simple solution? I need those features! :)

• When did my LaTeX files become TeX files!?

  - by andrz_001

  After transferring all my files onto a new machine, all files that were once LaTeX files (having the texnic center "T" icon) are now TeX files (having the TeX works icon --I don't remember installing that one!). But....the files are associated with the technic center! In other words, the files open with the texnic center, yet the "type of file" is "tex document". I'm using the same miktex distrubution and texnicCenter (both for windows xp) as on the old machine. Again, I don't know how/where I got this texworks on the new machine--assuming it came with windows. A question: Could these tex associations cause me any new surprises, anything unexpected? Like certain packages not working, etc? Because I can't have that!! Should I not fix it if it ain't broken!? For instance, one particular file yesterday would not produce any pdf output after compiling...after trying many things (other files compiled as they should have), I got to thinking to try it without the setspace for doublespacing!! And it worked. I have no idea why. Anyway.... Real question: How to revert to LaTeX file associations?? Rhetorical question: Would this question have better luck in ctan or stackoverflow? I guess I'll find out! Thank you wholeheartedly!

• How can I uninstall Broadcom Bluetooth software that won't disappear in Windows XP?

  - by T. Webster

  My situation is similar to this question for Windows 7, except my OS is Windows XP SP3. I have recently realized I made the mistake of buying a Bluetooth adapter and installing the Broadcom/Widcomm Bluetooth stack driver software. Now that I know that the software is no good, I want to uninstall it. Then I'll install the Toshiba stack for the Cirago adapter. Right now, when I double-click on the setup.exe file that came with the Cirago driver, nothing happens (it doesn't start setup). I've attempted to uninstall all Bluetooth driver software in Device Manager, and I don't see any remnants of any Bluetooth drivers there. But I do see that the little Bluetooth icon still persists: I don't see anything about Bluetooth, Broadcom, or Widcomm in Add/Remove Programs. I don't see any folder names Broadcom or Widcomm in Program Files folder, either. But I do see that Broadcom does show up in the registry with respect to Bluetooth, as shown here. I also renamed every file in C:\Windows\inf that starts with "bth" so that it ends with ".old". What should I do now to completely wipe this persistent Broadcom Bluetooth software off my computer?

• Apache is running the wrong version of PHP.

  - by The Rook

  I am trying to enable CURL in php, and possibly update php as well. I have run into a road block where Apache seems to be running the wrong version of PHP. Here is some evidence. #lsof | grep php httpd 18397 nobody 135w REG 8,3 242 528537 /usr/local/apache/modules/libphp5.so I download the latest php 5.2.13 and build from source. I run a service httpd stop, do a make install and then I manually overwrite /usr/local/apache/modules/libphp5.so just to be safe. Using ldd i can see that its my fresh binary compiled with curl (the old one doesn't have curl.) ldd /usr/local/apache/modules/libphp5.so | grep curl libcurl.so.4 => /usr/local/lib/libcurl.so.4 (0x0064e000) I execute a phpinfo() and 5.2.3 is being executed instated of my new 5.2.13 and "curl" is nowhere to be found. What am I doing wrong? Why is curl disabled even though its statically linked? This is a RHEL 5.5 system.

• Damaged partition after disk image

  - by Charles Gargent

  I am trying to clone/backup a disk with Windows 7 Pro 64bit on it. First I tried Easus Todo Backup and used disk clone option without sector by sector copy. I then plugged in the new drive and I get the following error. "Invalid or damaged Bootable partition" I then plugged the old drive back in and I am greeted with the same error. My next step was to try the sector by sector disk clone, but still I get the same error. I have tried fixing the mbr with the windows disk but that makes no difference. I have tried some other free tools and I get the same error. I have tried this on a different machine running Windows 7 Enterprise 32bit without this problem. I have done some searching and the only thing I can come up with is this post from the Acronis forums http://forum.acronis.com/forum/8254 suggesting that the bios is reading my disk geometry incorrectly. Can anyone shed any light on this, is there a way I can fix this either in the bios or repair the mbr every time I reimage it?

• PostgreSQL user authentication against PAM

  - by elmuerte

  I am trying to set up authentication via PAM for PostgreSQL 9.3. I already managed to get this working on an Ubuntu 12.04 server, but I am unable to get this working on a Centos-6 install. The relevant pg_hba.conf line: host all all 0.0.0.0/0 pam pamservice=postgresql93 The pam.d/postgressql93 is the default config shipped with the official postgresql 9.3 package: #%PAM-1.0 auth include password-auth account include password-auth When a user tries to authenticate the following is reported in secure log: hostname unix_chkpwd[31807]: check pass; user unknown hostname unix_chkpwd[31808]: check pass; user unknown hostname unix_chkpwd[31808]: password check failed for user (myuser) hostname postgres 10.1.0.1(61459) authentication: pam_unix(postgresql93:auth): authentication failure; logname= uid=26 euid=26 tty= ruser= rhost= user=myuser The relevant content of password-auth config is: auth required pam_env.so auth sufficient pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 500 quiet auth required pam_deny.so account required pam_unix.so account sufficient pam_localuser.so account sufficient pam_succeed_if.so uid < 500 quiet account required pam_permit.so The problem is with the pam_unix.so. It is unable to validate the password, and unable to retrieve the user info (when I remove the auth entry of pam_unix.so). The Centos-6 install is only 5 days old, so it does not have a lot of baggage. The unix_chkpwd is suid and has execute rights for everybody, so it should be able to check the shadow file (which has no privileges at all?).

• SSD causing 100% CPU usage in Apache/PHP

  - by Tim Reynolds

  I wanted to increase the performance on my development laptop so I added an Intel 320 Series SSD as my primary drive. Everything is amazingly fast, as expected, except Apache/PHP. I develop Magento by using an Ubuntu 10.10 virtual machine. Information: Host OS: Win 7 Professional 64bit Guest OS: Ubuntu 10.10 32bit Processor: i7 Chipset QM55 SSD: Intel 320 Series 160gb 30% full HDD: Hitachi 320gb 50% full (in side bay using an adapter) Laptop: Lenovo T510 Using: Shared folders Apache Version: 2.2.16 PHP Version: 5.3.3-1 APC Version: 3.1.3p1 APC Memory: 128M Using tmpfs for cache, log, session directories in Magento In the VM running on the SSD (VM files and source files are on the same drive) loading a product page in the Admin takes on average 26.2 seconds and uses 100% CPU for nearly the entire time. In the VM running on the old HDD loading the same page takes on average 4.4 seconds. It mostly uses around 40-50% of the CPU while rendering the page. I have read this post: Performance issues when using SSD for a developer notebook (WAMP/LAMP stack)? It says to change some settings in the bios. I have turned any and all power management features off in the bios. I can't for the life of me understand why this would be happening.

• Can Subject Alternative Name accommodate multiple virtual mail domains?

  - by Lawrence

  I am currently running a postfix server with self signed certificates serving one mail domain, mycompany.com, the mail server is mail.mycompany.com and so is the CN of the certificate. Now, I need to add a new domain to it. The new domain name is mycompany.net to the same server. Since the users already have the root of the old certificate, I'd like to reuse that. However, I'd like to issue a new certificate so users using the SMTP from Outlook/Thunderbird of mail.mycompany.net do not get warnings. If I understand correctly, if I issue a new certificate with CN=mail.mycompany.com and a subjectAltName=DNS:mail.mydomain.net and have postfix serve this, the client will not complain either way about the cn not matching the target host name. Am I correct in this assumption or am I misunderstanding the concept of Subject Alternative Name? Just to avoid conversation, I do not want to have users on mycompany.net addresses use the mycompany.com server because I might (not a technical issue) have to split up into two different locations, and I want to produce an easily migrateable setup.

• What could cause TFTP reloaded Cisco `running-config` on 871 to fail?

  - by xtian

  Cisco CCP Write Configuration borked my 871w config while I was trying to setup port forwarding. I went through the basic steps to reconfig the router. I looked to see if I could just reset the router. Nope. I tested the 871's flash memory with fsck to see if there was hardware failure. Nope. Then I rewrote the minimal config for TFTP (which is the same for Cisco's CCP app.). Thne, I successfully uploaded a previously working running-config from Win Vista using SolarWinds TFTP Server, unfortunately the restore was not entirely successful. The old running config was saved to the 871's startup-config and I can login using console port. Some other things that are working are the hostname and welcome message but that's about it. Startup shows an error SETUP: new interface NVI0 placed in "shutdown" state after tftp. The missing light on the access point modem for ethernet link show the 871'a outside FE4 is not working. SO...what's the possible problem with reloading a previously working config (approximately 4 months with the same config) via TFTP? Is there something I can look for on the 871 to verify the config? Or on Vista to validate the config file itself before I transfer it? Or, is this there a common TFTP issue? UPDATE. I missed the instruction from Cisco's TFTP page to delete aaa lines from the config (although a video from a SuperUser user didn't make this point in his most excellent demo). There were several lines of this sort, I deleted them and uploaded again. However, they're back. I assume they're added automatically? [nope, see answer] UPDATE 2. The reload of previous settings was successful, but this error remains. I don't even know now if it was there before or not. It seems irrelevant to the question.

• Can't Connect w/ SQL Management Studio After Domain Change

  - by Sam

  Our old Small Business Server 2003 (acting as our domain controller) was on the fritz, so we replaced it with a new Windows Server 2008 box and set the server up as our new domain controller. In hindsight, it may have been a mistake, but we set up the new server as a replacement and tried to keep as much the same as possible, including the DOMAIN name. The problem was, that even though the domain name was the same, the guest computers somehow still realized it was not the exact same domain. We had to unjoin and rejoin the domain and port over everyone's documents and settings. This morning, when I attempted to connect to my local SQL Server Instance, it was saying that my login failed. When I tried to use the SQL Management Studio, it throws the error "Package 'Microsoft SQL Management Studio Package' failed to load" on startup, then exits without giving me a chance to change the login. I am using Mixed Authentication and have an administrative account as a backup. Ideas? If there is a more appropriate stack, please let me know where to put it.

• Dell Studio 1555 not starting up

  - by Abhishek

  This is a 3-year-old laptop. I never had a big problem with it until now. I updated Kubuntu the night before yesterday. And Firefox got updated to version 18 and a few other related packages got updated. Then I shut down the laptop and restarted it, but it failed to start. I could hear the fan and the hard disk and the optical disk drive initialize. And the power button also lighted up. But there was no video - no POST or BIOS menu. I even opened the laptop up to the point when only the motherboard was the only thing attached to the base cover. I took it to the technician this evening. He checked it casually, and said that it might be a motherboard problem and will cost quite a bit to fix. Though he was not sure and said that he will give me a call after confirming the problem. Has anyone else had the same problem? What was it and what was the fix?

• USPTO site asks for Quicktime Plug-in which I already have installed. Why?

  - by Kensai

  Whenever I try to watch the images of a patent in the USPTO site (example) using Firefox, the browser asks me to download the latest Quicktime, manually. This is totally strange because I already HAVE the latest plug-in (it even appears on my Firefox add-ons list). In the past I have only been able to see patent images using Safari. But never with Firefox. Is it a USPTO problem or a Mozilla one? Is there a way to fix the problem? edit: I can't see TIFF images neither with Internet Explorer (both 32-bit and 64-bit versions) nor with Chrome. All these browsers don't know how to open embedded TIFF images because they don't recognize the installed Quicktime plugin. A USPTO conspiracy to promote Safari? Come to think of it, I had this problem in my old computer as well. It had a 32-bit Vista OS, now I have 64-bit Windows 7. I hate TIFF and can't find Mozilla-specific information anywhere.. Arghh, am I the only one here with this freak problem?!

• RDP Connection to Windows 7 stays really slow

  - by Pavlo

  I have an Issue with connecting to Windows 7 via RDP. I can open an RDP Session, but regardless of any settings, the responce times are really long. This in particulary is the case when opening a web page in a browser. I've tried IE, Firefox and Google Chrome. I also use RDP connection to a Windows 2008 Server from the same client machine, and the speed is very normal with all features turned on. We have Gigabit Ethernet here. So I think it can not be the client's fault. What concerns Windows 7 Machine, I've tried shutting all the sraphic features off and turning the color levels to 256 colors. Result - the same. If I work locally on the machine - I can not see any lags. What else have I tried: Using old RDP 5 Client from Microsoft Setting network autotuninglevel as seen here Do You have some ideas? Thanks in advance! Update the problem seems to be with rendering window contents. All the window borders and pannes are rendered pretty quickly, but the content shows up very slowly. Also mouse movements are recognised by the Win 7 box only after some period. Are there some hidden settings in the RDP, where one could turn some advanced features off or turn some caching on? I use Bitmap Caching, but this apparently doesn't help.

• Windows 7 boot issues

  - by Michael

  Ok, I tried to install linux and dual boot my laptop with 7 ultimate. I messed up. When I tried to boot to 7 it said no. Something along the lines of device not found. So I being young and stupid I uninstalled linux which I could boot into, and I still could not boot to windows. Next step was to run the startup fixes from the boot cd. Swing and a miss, I also ran the fixmbr and fixboot. Which brings us up to my current place. I installed 7 again on my blank partition in hopes I could access my other partion. No dice. So my question to yall is how can I fix my original filesystem or at least get to the stuff on it. In the new 7 install the old partion does not even have a drive letter. That is my sad story any help would be apreciated.

• Windows 7 pc freezes for an indeterminate amount of time after unlocking

  - by pikes

  Not sure if this type of question is appropriate for this forum, but I've tried everything I can think of to solve this problem aside from format/reinstall. I recently got a new work PC (Dell optiplex 755) with windows 7 professional x64. Standard developer software installed for .net development: VS2008, VS2005, SQL management studio, office 2007, etc. Recently I've been having this weird problem where after I lock my pc, when I try to unlock it, the screen will be black for awhile after unlocking. I can ctl+alt+del and put my password in but then it just goes black. The amount of time on the black screen seems to be related to the amount of time I am away from my PC. If only away a few minutes, it'll take about a minute to get to the desktop. If away for an hour, could take up to 15 minutes. If I lock it and go home for the night, I have to restart my PC in the morning (I've let it sit for an hour after a night of being locked and nothing happened). It doesn't do it every time but definitely the majority of the time. One weird thing I've seen is that if I remote into my machine before trying to log back in it does not do it. I uninstalled all software back to the point when I remember it started happening and it still does it. I was using this PC for a few weeks without this problem happening at all. Anyone know what my next troubleshooting steps could be? My IT department tried to fix it by moving my old profile to another disk and having me log in, effectively recreating a profile from scratch but that didn't solve it. As I said above if this isn't the right forum for these types of questions please let me know. Thanks in advance!

• Split big Apache log to folder structure

  - by Dough

  I just changed my Apache log behavior because it was making me having very BIG files... So I now use cronolog to split my logs to log/httpd/2012/11/access_2012.11.30.log for exemple, pattern : %Y/%m/access_%Y.%m.%d.log I now want to split my old 42GB file to the same structure but really don't know how to do that efficiently. I tried some simple commands with cat, egrep, awk... but really don't know how to handle all that in a more powerful script. Here is how the log looks like : x.x.237.134 - - [08/Apr/2011:14:43:09 +0200] "GET... x.x.50.15 - - [08/Apr/2011:14:43:09 +0200] "GET... [...] x.x.254.19 - - [28/Feb/2012:15:24:48 +0100] "GET... So I need for yeah line to get : year %Y (ex. 2012) month %m (ex. 11) day %d And to push out the entire line to : %Y/%m/access_%Y.%m.%d.log Can someone give me clues to get that working ? Thanks a lot for your interest.

• PC can't detect second RAM installed

  - by kulwinder

  I have PC with 512 MB RAM installed (motherboard manufacture MICRO STAR, chipset P4M800), pc was running very slow so I decided to upgrade the ram. I installed CPU-Z and check the ram installed on the machine, also had a look at the stick installed. 512 MB PC 3200 400 MHz DDR but my mother supports 200 MHz and it was working ok. So I bought 2GB which I checked on manual that it support upto 2 GB Ram. So I installed 2GB PC 3200 400 MHz same as the old one, I plugged in both eventhough motherboard only support upto 2 GB but system spec only shows 512 (deducts 64 MB shared vga memory) I checked on CPU-Z, it detects both, slot 1 512 MB, slot 2 2048 MB, comparing screen for both slots, both the same, volt 2.5, frequency 166 MHz and 200MHz, only difference on those is 2gb ram shows under timings table 133MHz 166 MHz and 200MHz but 512 MB shows only 166MHz and 200MHz. I checked on Google and can't seems to figure out whats wrong with it. If I only plug in 2GB. Pc doesn't boot up like ram not working.With only 512 MB plugged in seems ok. Please help.

• installing Conkeror on Ubuntu 12.04

  - by Menelaos Perdikeas

  I am reading the instructions on conkeror site (and elsewhere) on how to install conkeror on Ubuntu (I am using Ubuntu 12_04 LTS) and it seems that the correct sequence is: sudo apt-add-repository ppa:xtaran/conkeror sudo apt-get update sudo apt-get install conkeror conkeror-spawn-process-helper The first step (apt-add-repository) seems to execute without a problem, giving the following output: You are about to add the following PPA to your system: Conkeror Debian packages for Ubuntu releases without xulrunner (i.e. for 11.04 Natty and later) More info: https://launchpad.net/~xtaran/+archive/conkeror Press [ENTER] to continue or ctrl-c to cancel adding it Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret- keyring /tmp/tmp.Re7pWaDEQF --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver hkp://keyserver.ubuntu.com:80/ --recv CB29CBE050EB1F371BAB6FE83BE0F86A6D689050 gpg: requesting key 6D689050 from hkp server keyserver.ubuntu.com gpg: key 6D689050: "Launchpad PPA for Axel Beckert" not changed gpg: Total number processed: 1 gpg: unchanged: 1 However, the apt-get update seems unable to fetch packages from the newly added PPA, with its output ending in: Hit http://security.ubuntu.com precise-security/restricted Translation-en Hit http://security.ubuntu.com precise-security/universe Translation-en Err http://ppa.launchpad.net precise/main Sources 404 Not Found Ign http://extras.ubuntu.com precise/main Translation-en_US Err http://ppa.launchpad.net precise/main i386 Packages 404 Not Found Ign http://extras.ubuntu.com precise/main Translation-en Ign http://ppa.launchpad.net precise/main Translation-en_US Ign http://ppa.launchpad.net precise/main Translation-en W: Failed to fetch http://ppa.launchpad.net/xtaran/conkeror/ubuntu/dists/precise /main/source/Sources 404 Not Found W: Failed to fetch http://ppa.launchpad.net/xtaran/conkeror/ubuntu/dists/precise/main/binary-i386/Packages 404 Not Found E: Some index files failed to download.

• Computer turns itself on after any off mode

  - by Patrick

  Whenever I shut down my computer, or put it in sleep/hybernate, it turns on after two seconds. It doesn't post, it just powers on and then idles. To actually turn it off, I switch off the psu. The problem is now, whenever I switch the psu on and try to boot, it doesn't always turn on. It takes a good amount of flicking the psu switch on and off before the motherboard lights up. So far I've determined the things its not: its not caused by the mouse or network waking up the computer. I've been able to go into hybernate for the past year. And all "wake on X" settings in the bios are diabled. its not a scheduled task waking up the computer at a given hour, it occurs every single time its not due to an upgrade or new installation, since I haven't done either in a very long time I'm sure its a hardware issue. So I'd like to know, is my psu dead, or the motherboard? The psu is an Antec Earthwatts 600w, the motherboard is an Asus P5Q-E, both one year old.

• How to remove static IP from Mitel 5312 and enable DHCP

  - by jimbo

  I'm not sure this is the right forum for this question -- although I'm confident I'll be told if not! -- but I've read the fine manual (at least, such a manual as I have), I've googled and I cannot get any insight into where to even start solving this problem. I have a bunch of Mitel 5312 handsets, talking to a 3300 ICP controller. Some handsets are at a remote location, get an address from my DHCP server over there, and use the Mitel "Teleworker" extension to connect in over the Internet. The remaining handsets were set up with static IPs by a BT-supplied engineer, on the same subnet as the ICP itself. So far, so good. I have one remaining teleworker licence, and need to move a handset from the home location to the remote. I've managed to boot it and configure teleworker, but I cannot for the life of me see where I tell it to forget its static IP, and make a DHCP request. Any ideas? Should I be looking on the controller, or holding magic combinations of buttons on the handset itself? EDIT: Following some advice from Robert, below, I've broken out a spare device and reassigned the profile for this user's extension to the MAC of the new phone, and a new profile to the old MAC. Unfortunately this still doesn't get me anywhere -- the new handset now asks for the teleworker install password. I suspect I'm going to have to get a Mitel engineer involved here, since I've never been given that password... Unless anyone has any great ideas?

• Monitor goes black for a few seconds

  - by privatehuff

  I have a Hanns G 28" monitor, Model # HG281D It has its issues (viewing angle sucks) but has been functional and solid, great for desktop stuff. Worked without any sign of any problems for 6-12 months. However, now the monitor "goes black" for about 2-3 seconds, almost like when you click "detect display" It does not turn off (power light does not go amber) The computer is completely unaffected and the video mode never changes when the picture returns. The computer is fully responsive and will keep playing music or taking my keypresses during the time I can't see anything. (it just happened and I kept typing, etc) It happens on multiple computers across several operating systems. (I have an 8-port iogear KVM switch that has several computers connected) But, it seems to happen only on certain computers. I have a hackintosh that does it, a windows 7 PC that does not, a lenovo laptop that does not, and my old ubuntu 8.10 box did not do it, but my new mint 8 box does do it. I've check the connections and tried changing out the power cable and the vga cable. Sometimes it won't happen for hours (or days) and sometimes it happens several times per hour. It was happening many months ago, did not happen for months, and has now started happening again. Does this make any sense? What could it be?

• Windows XP Boot Issue - Diagnosing A Hard Drive Failure

  - by duffymo

  My five-year-old HP desktop running Windows XP SP3 wouldn't boot from the hard drive yesterday afternoon. I would see the boot sequence begin, then nothing but a black screen. Fortunately, I had just done an Acronis backup to my external drive in the morning, and I have a bootable USB key. I put the USB key into the drive, powered up the machine, and put the USB key first in line in the boot sequence. Voila! My machine came alive. But now I'm confused as to what the problem is and what to do next. I assumed that my hard drive was toast. But now that the machine is alive I can see files on my C: drive that have changes I made just yesterday. Clearly the drive is not dead. Here are my questions: What could explain my inability to boot from the hard drive? What would a remedy be? What's my best course of action? Should I replace the hard drive with a new one? If I replace the hard drive, do I reinstall the OS and apply the backup I did yesterday? If I decide that re-installing Windows XP makes no sense, how do I get back the Acronis backup that I did yesterday? I don't want to lose that. UPDATE: I just learned one more key fact. I'm having some work done on my house. I neglected to shut my machine down before the contractor came. My wife said he shut down the power to do some work on a circuit and then powered the house back up. I have a surge protector, but is it possible that cycling the power did some damage?

• Thumbnail generation with imagemagick doesn't render the correct colors

  - by Bastien

  Generating thumbnails of PDFs with imagemagick sometimes renders incorrect colors. We're using an old version of imagemagick (6.5.7-8, that's the version installed on the heroku servers). Here is the command we're currently using: convert -size "725x1200>" -colorspace RGB -flatten -density 300 -quality 100 input.pdf output.jpg I've tried using different colorspaces like sRGB,YIQ,.. but none of them are rendering the color correctly. Using imagemagick-6.7.7-6 locally works so I've tried to bundle the 'convert' command within my application /bin directory, the command works but the result is still wrong, so it seems that the problem comes either from another imagemagick command used by 'convert' or from another library. Here's an example of the outputs: Correct output: http://i.stack.imgur.com/gf9eG.jpg Wrong output: http://i.stack.imgur.com/imUeD.jpg Strangely, with some pages of the same pdf the output is always correct. Any idea which library or command could be the issue, or if there is a proper set of options to pass to imagemagick to always get it right? Thanks in advance for your help.

• need advice on data center move, communication with both facilities during transition

  - by Brian Roden

  We are beginning the process of moving to a new facility. Office and warehouse operations will both be moving, and we must get shipping operations up and running at the new location while continuing to ship from the old location. Our contract with some third-party warehouse tenants requires two business day turnaround (only weekends and holidays excluded), so we can't have major downtime during the move. We would like to keep our 172.16.60/61.xxx internal address space in use throughout the move. Is it possible to keep using this same internal range, and have our existing WatchGuard Firebox 520 and whatever router we get for the other location (preferably the same model) just treat both locations as one network, leaving our host IPs the same throughout the move? Renumbering the servers when they move isn't a big deal, but our wireless terminals for order picking in the warehouse have fixed IPs (and a fixed IP, non-DNS reference to the host they speak with) and would be a massive undertaking to reconfigure when the servers move (each device would have to be reconfigured at least 2 times -- some when we start using them in the new building and the host is still here, all of them in both locations when the host moves to the new building, and the rest when they finally make the move to the new building). We're trying to avoid that if possible.

• iptables forwarding to a dummy interface

  - by madinc

  Hi, I'm trying to accomplish the following: I have a box with a service listening on a dummy interface (say 172.16.0.1), udp port 5555. Now what I'd like to do is to take packets that arrive on interfaces eth0 (1.1.1.1:5555) and eth1 (2.2.2.2:5555) and forward them to the service on the dummy interface, and have replies go back to clients out the same physical interface they came in. Clients must think they're talking to 1.1.1.1:5555 or 2.2.2.2:5555. I think I need a mix of iptables rules and packet marking, plus some iproute rules (if it's possible at all). What I tried is to catch packets coming in from eth0 and eth1, udp port 5555, and mark them with 1 and 2 respectively, and --save-mark in the connmark. Then I used a DNAT to 172.16.0.1. The service seems to be getting the packets. Now I'm not sure how to do the reverse. It seems that for packets originating from the box, you can't do anything before the routing decision, but that would be the place to restore the marks, and thus make a routing decision based on those. Here's what I have so far: iptables -t mangle -A PREROUTING -d 1.1.1.1 -p udp --port 5555 -j MARK --set-mark 1 iptables -t mangle -A PREROUTING -d 2.2.2.2 -p udp --port 5555 -j MARK --set-mark 2 iptables -t mangle -A PREROUTING -d 1.1.1.1 -p udp --port 5555 -j CONNMARK --save-mark iptables -t mangle -A PREROUTING -d 2.2.2.2 -p udp --port 5555 -j CONNMARK --save-mark iptables -t nat -A PREROUTING -m mark --mark 1 -j DNAT --to-destination 172.16.0.1 iptables -t nat -A PREROUTING -m mark --mark 2 -j DNAT --to-destination 172.16.0.1 # What next? As I said, I'm not even sure it can be done. To give a bit of background, it's an old OpenVPN installation that cannot be upgraded (otherwise I'd install a recent version that supports multihoming natively). Thanks for any help.
