• Mapped network drive connection timeout

  - by Terix

  I have server "Alpha" and server "Beta". Server Beta has a shared folder, that is mapped on server Alpha as "X:" On server Alpha there is a .vbs script that runs and take some files on local drive and copy them on X: drive. My issue is if no user log on server Alpha for a long time, it seems like the tcp connection underneath the mapped drive has a timeout, and the vbs script fails on the copy of file. As soon I log with remote desktop on Alpha server, the .vbs is successfull on the copy of the files. I have made many tests, using file logs to check what was happening and I found no way to refresh the connection and let the .vbs be able to copy files unattended.. I have always to log with remote desktop on Alpha server to refresh the connection and let the .vbs copy the files without issues. What can I do to avoid to log every time? The .vbs script runs 3 times a day and is very annoying. I do not have control over server Beta so I cannot change anything there, and I am very limited on changes I can do on server Alpha ( I cannot change registry and that sort of things)

• Howto get exit code of a script started in screen session

  - by Bettina

  Hi folks, I am currently creating a backup script which uses screen to start a backup job with rsync inside a screen session. The backup jobs are started as follows. screen -dmS backup /usr/bin/rsync ... As soon as the rsync job is finished, the screen session is terminated automatically. To make sure, that the backup was successful, I would like to check the exit code of the rsync job but unfortunately I really don't know how to get the exit code after the screen was terminated. Does someone have a good idea how to automatically check, if the rsync job was successful or not? Would be great if someone does. I already thought about using a temp file but like this: screen -dmS myScreen "rsync -av ... ; echo $? /tmp/myExitCode" but this unfortunately does not work. Then I thought about using stderr like in the example below: screen -dmS myScreen "rsync -av ... 2 /tmp/rsync-sterr None of my ideas worked out so far, since stderr is not written when I use the command above. :-( ? Would be great if someone has a good idea or even a solution. Cheers, Bettina

• Is there any way to synchronize AD users with Office 365 but still be able to edit them online?

  - by Massimo

  I'm performing a migration to Office 365 from a third-party mail server (MDaemon); the local Active Directory doesn't include any Exchange server, and never had any. We will need directory synchronization in order to enable users to log on to Office 365 using their domain credentials; but it seems that as soon as you enable directory synchronization, you can't perform any action anymore on Office 365 users: all changes need to be made on the local Active Directory, and then replicated by the synchronization process. For ordinary users with a single e-mail address and standard features, this is not a big problem; but what about users which need an additional address? What if I need to configure some nonstandard setting, like "hide from address list" or a custom mailbox quota? From what I've gathered, the only supported way to do this, as you can't directly edit Office 365 objects anymore after synchronization is enabled, is to extend the local AD schema with Exchange attributes, and then manually edit them (!). Or, you can install at least one local Exchange server, and then use the Exchange administrative tools to configure the required settings. Is this correct or am I missing something? Is there any way to synchronize user accounts and password, but still be able to edit user settings directly in Office 365? If not (everything really needs to be set locally and then synchronized), is there any simpler way to do this than manually editing LDAP attributes or installing a local Exchange server?

• "Document in ADF" on Canon MX340

  - by Michael Donohue

  I have a Canon MX340 multifunction printer. Recently, it keeps saying "Document in ADF" when I turn on the printer. I've tried clearing this multiple times, but as soon as the feeder wheels stop turning, in an attempt to clear the document feeder, it just pops up the same error again. This is particularly annoying, as it blocks all functions on the device - I cannot print, even though printing has no interaction with the document feeder. I've opened up the feeder device, as much as can be done with fingers alone. There just doesn't seem to be anything in there. I ran a sheet of paper through about six times, just to see if some dust might be getting in the way, and I've blown out the feeder with air. Still nothing. At this point, I don't care too much about the ADF working, I just want to disable whatever sensor is tripping this error message. Any ideas? I found this thread online, where a user has the same problem. But no resolution was reached there.

• Matched or unmatched drives for RAID arrays?

  - by Will

  Looking around there is conflciting information on this, with some strongly suggesting one or the other. From my understanding the issue with matched drives is that the wear on both drives is more or less the same, so the potential for the second drive failing with or very soon after the first is pretty high. People also claim matched drives give substianatally higher performance however assuming the unmatched drives are more or less the same (eg 2, 1 TB STATA II 7200rpm drives with 32MB cache), would the minor differences between say a Seagate and a Western Digital one (say one has a 128MB/s read rate, and the other a 150MB/s read rate, as well as I guess various other minor differences) actually cause any notable performance loss, ie potentialy worse than two matched 128MB/s drives, or does RAID not really care and give you essentially an optimal solution (eg upto 278MB/s total read speed for RAID 0 and 1) and similar for other RAID with more "unmatched" drives (5 and 1+0 come to mind as possibilities)? Also I couldnt find much info on how this is different on different RAID setups, eg RAID 0 or RAID 1, software or hardware RAID, etc. I'm assuming such things have an effect, and thats it's not all the same for RAID in general?

• Linux: 3 Monitor PCI-e Graphics card (without tremendous pain)?

  - by N Rahl

  As we are all painfully aware, the only way to get multiple monitors AND compositing (Compiz) on Linux is to use a single graphics card that can drive both (or in my case all three) screens. I bought a Radeon 5750 specifically because it claims to able to drive 3 monitors. I can plug in 3 monitors (2 DVI, 1 HDMI) and the Catalyst Control Center shows all 3, but only 2 can be enabled at a time. I'll post the exact error message here soon, but it's very useless. So I'm going to assume that either the 5750 doesn't support 3 monitors, OR, more likely, ATI couldn't be bothered to add that support to their Linux drivers. So this is a multipart question: First, can anyone suggest a PCI Express Graphics card that can run 3 screens on linux without tremendous pain? I'm looking for something where you install the driver and all three screens "just work". Does such a card exist? Second, if you have a 5750, have you been able to get it to do 3 monitors? I'm running Ubuntu 10.04 at the moment. Thanks, Nick

• Excel controls not visible for certain users

  - by Nossidge

  One of the users of an Excel program I've written is having a weird problem. None of the control objects (Command Button, ComboBox, etc.) are visible to him when he opens the file on his laptop. He is using Excel 2003, the same version I used to create the program, and enables macros using the pop-up when the file loads. I have Googled this, and have found these people who seem to be having the exact same problem, with various versions of Excel. Unfortunately, none of their questions were answered. I can't really explain it any better than this user: If I enter design mode and pull a control from the control toolbar onto a sheet all I see are the drag handles. When not in design mode I have to feel around with the mouse and can click the button which executes the button click code correctly and opens another sheet where again I have to feel around for the buttons to return me to the original sheet. The button I managed to click is now visible but as soon as I click anywhere on the sheet it disappears. I have verified that the visible property of the buttons is set and that the Show All Objects on the Options View tab is selected. If I pull buttons from the Forms toolbar onto a sheet they are visible. If I try to find Objects using F5 when not in design mode Excel reports no objects on the sheet. So, Super Users, can you help? UPDATE: Thanks for your replies, but much like the person in the ozgrid link, the problem has gone away. Not sure why it went, but I can confirm that the user rebooted again and also started up other Excel files that didn't contain controls in the interim. Perhaps that fixed it, or maybe it'll be back again. I'll keep udating with progress, and close if the problem doesn't reoccur for the next few days. Thanks again.

• Setting up Virtual Host in Fedora Core 15 using apache

  - by Roland

  I'm trying to setup a couple of Virtual Host files on my Localhost PC running Fedora Core 15. Now I get this working, but now onloy one Virtual Host site works, and if I type in 127.0.0.1/test/testApp.php which is not related to the Virtual Host site , I get redirected to the Virtual Host site. Here's what I did. I created a new folder called virtualhosts in /etc/httpd/ where all my host files are stored in the following format site.conf In /etc/conf/httpd.conf I enabled NameVirtualHost *:80 and included the host files at the bottom of the config page like this Include virtualhosts/*.conf In /etc/hosts I added the line 127.0.0.1 website No when I run sudo httpd -t I get Syntax OK I restart apache and then the Virtualhost works, but as soon as I add other hosts and only use 127.0.0.1 as above it still links to the original host. Am I doing anything wrong here or left out something? An example of my Virtual Host file looks like this <VirtualHost *:80> ServerAdmin [email protected] DocumentRoot /var/www/html/website/ ServerName website ServerAlias website ErrorLog logs/dev-error_log CustomLog logs/dev-access_log common Alias /blog /var/www/html/blog/ <Directory /var/www/html/website/> Options FollowSymLinks Allow Override All Order allow,deny allow from all </Directory> #php_value error_reporting E_ALL & ~E_NOTICE & ~E_DEPRECATED php_flag display_errors On php_value date.timezone Europe/London </VirtualHost>

• How can I monitor network traffic?

  - by WIndy Weather

  I have a home network with about 10 devices including BluRay player [netflix] and both windows and linux machines. I need to collect network traffic statistics so that if questions come up about how much traffic I'm using I have the answer independent of my ISP. I've looked at DD-WRT, but I see that even buying a new router that will be supported is a problem since I might get the wrong version of the hardware. I have a DIR-655 and a DIR-501 - neither of which is supported. I don't mind buying new hardware, but it looks like a crap-shoot to get one that will work. DD-WRT looks like a bad solution unless someone knows of a place to get a router that is guaranteed to work. Does someone know of an arduino or other SBC solution? I have plenty of NAT routers already, so I just need traffic statistics for external traffic. The network is GBit Ethernet inside and Cable / soon to be DSL outside. The DIR-655 only gives me "packets", not bytes transferred oddly enough. Thanks, ww

• Safe to remove Python2.6 files?

  - by darkfeline

  I'm using Linux Mint 11 (will upgrade soon), and I've noticed that, even though I don't have any python2.6 packages installed with apt, there's a bunch of residual python2.6 files scattered around my drive, including, but not limited to, dist-packages in /usr/lib/python2.6 and various /usr/share stuff. Is there any way to test if these files are still being used? I'm tempted to sudo rm -rf the lot of them, but I'm scared it'll break stuff. Also, does anyone have any idea where these files could have come from? I believe I had python2.6 installed once upon a time, but I made sure to --purge them, so there shouldn't be any trace of them left, right? EDIT: after using a quick script to check all of the files, it appears most of them belong to important packages, so I won't try weeding out the few which I know are probably useless. Although I am curious why so many packages have python2.6 files when I don't even have it installed. These files are not associated with any packages and I'm not sure if they are safe to remove: /usr/bin/ipython2.6 /usr/lib/python2.6/dist-packages/distribute-0.6.15.egg-info /usr/lib/python2.6/dist-packages/easy_install.py /usr/lib/python2.6/dist-packages/IPython /usr/lib/python2.6/dist-packages/ipython-0.10.1.egg-info /usr/lib/python2.6/dist-packages/setuptools /usr/lib/python2.6/dist-packages/setuptools.egg-info /usr/lib/python2.6/dist-packages/setuptools.pth /usr/lib/python2.6/dist-packages/site.py /usr/lib/python2.6/dist-packages/wx.pth /usr/local/lib/python2.6 /usr/local/lib/python2.6/dist-packages /usr/local/lib/python2.6/site-packages /usr/share/man/man1/ipython2.6.1.gz

• MySQL Memory Limit Windows Server 2003

  - by Matt

  I am running MySQL 5.0.51a on Windows Server 2003 Standard Edition on an HP DL580 G4 with 3GB installed. One of my database tables has grown to 5.3 GB with an index file of 2.5 GB, which I believe is causing MySQL to be slow due to having to constantly load and unload the index file when updates are made to the table. The server itself seems to be performing OK because MySQL is only using about 500MB of memory (there are other apps running on the system, but MySQL uses the most memory). The table is fairly active with new records getting adding all during day but no deletes, ever. The MySQL server has up to 600 connections allowed, but only small number (10 or 20) would actually be writing to this table. I increased the memory limits in MySQL but since the max connections is so high I don't think I can give each connection 1GB without risking a problem. Is there some tuning that would let just certain connections get a lot of memory? So I have started to look for alternatives to avert the crisis I know is coming soon. Some of the options I have: Upgrade to Server 2003 Enterprise to install 64GB of memory. Question: would 32 bit MySQL be able to access more than 2GB? Would that be 2GB per thread? That would still be smaller than the index table size so it might not solve the problem completely, but it would be better than now. Upgrade to Server 200x 64 bit and MySQL 64 bit. Switch to a *nix 64 bit server. If anybody has suggestions for things to do in the meantime, opinions on which way to go, or other things that I have overlooked I would appreciate the help. Thanks

• What to do after a fresh Linux install in a production server?

  - by Rhyuk

  I havent had previous experience with the 'serious' IT scene. At work I've been handed a server that will host an application and MYSQL (I will install and configure everything), this will be a productive server. Soon I will be installing RHEL5 to it but I would like to know like, if you get a new production server, what would be the first 5 things you would do after you do a fresh Linux install? (configuration/security/reliability wise) EDIT: Added more information regarding the server enviroment and server roles: -The server will be inside my company's intranet/firewall. -The server will receive files (GBs) in binary code from another internal server. The application installed in this server is in charge of "translating" all that binary into human readable input. Server will get queried to get this information. -Only 2-3(max) users will be logging in. -(2) 145GB HDs in RAID1 for the OS and (2) 600GB HDs in RAID1 also for data. I mean, I know I may not get the perfect guideline. But at least something thats better than leaving everything on default.

• The Web Hosting Connundrum for "not quite" developers

  - by saltcod

  Hey all, Apologies if this post feels like its been covered elsewhere, but I don't think it has. I've been down a winding web hosting road. To date, I've tried: Joyent, Media Temple, Bluehost, Hostgator, and finally Linode. The reason for switching are likely obvious to everyone: speed. With the exception of the lightening fast Linode, all of the shared hosts are absolutely sloooow. What do do when you're not really a "developer" While I'v grown addicted to the speed of Linode, I really don't feel like its where I should be. I have this nagging feeling in the back of my mind that one of these days (likely soon), I'm going to run into something that i won't be able to figure out and i'll have days worth of downtime. Just the other day, for example, I realized that one of my domains wasn't sending emails. After 4(!) hours looking into the problem, I still can't get sendmail or postfix to work. Four hours!! I want to be a Drupal expert, not a Ubuntu expert That's really the heart of my problem: I spend way too much time learning Ubuntu's ins-and-outs, and not nearly enough time working on Drupal. So here goes: Is there a web host out there anywhere that offers the speed of Linode, but will let me focus on Drupal instead of sys-admin-ing? Thanks! [ I know, I know. There are going to be lots of people who read this saying - "just learn Ubuntu like a real developer". And I get that. I do. But when I work full-time and try and develop some of these sites in my evenings and weekends, I'm really feeling like the sys-admin stuff gets in the way.

• Is there any reason this cronjob would fail in cron, but not on the command line?

  - by Treffynnon

  I have written a little one liner that will email me when a list of files changes - I used sha512 to generate a list of hashes and then periodically check that those hashes still match. */5 * * * * /usr/bin/sha512sum --status -c /sha512.sumlist && echo "Success" > /dev/null || echo "Check robots.txt and index.html in /var/www as staging sites are now potentially exposed to the world and the damned googlebot" | /usr/bin/mail -s "Default staging server files have changed" [email protected] It works fine on the command line with: /usr/bin/sha512sum --status -c /sha512.sumlist && echo "Success" > /dev/null || echo "Check robots.txt and index.html in /var/www as staging sites are now potentially exposed to the world and the damned googlebot" | /usr/bin/mail -s "Default staging server files have changed" [email protected] As soon as I run it as a cronjob though it emails every time it runs with the failure message instead of only when the sha512sum check should fail. Is there something silly I have missed in a rush? I forgot to mention that I am running an Ubuntu machine.

• Buying an old laser printer -- what will need to be replaced?

  - by marienbad

  Hi all -- as you can see I'm new. I do IT and wiring for a small local shop but I never deal with printers. I do a LOT of printing, and I'd like to stop spending as much money on it. On my local CL, there is an HP 8100DN (duplex network) printer for a very good price (and the toner is a quarter-cent per page). It has printed 200,000 pages and I don't yet know anything else about it. The model was released in 1999. So my questions: What are the parts that tend to need service on laser printers? On ebay, I see fusers, rollers, DC power boards, and motors. What would you expect to replace soon at 200,000 pages? Are there any good "tests" to find out if certain parts are near failure? Do you have anything to say about the HP 8100 specifically? The bottom line for me is that if there's any chance of repairs costing more than $100, it's not worth it for me.

• php-cgi.exe Taking out server, multiple running

  - by Alex

  I have been using ZendServer CE for over a year and have never had a problem. Recently, about a week or two ago I have found my server to be acting up and even causing RDP to be un-connectable. After some looking around I have 20, 25, 30+ php-cgi.exe running. With my IIS7 service starting with Windows once my server started all these php-cgi.exe would start running (even though the limit is 10) and I could not even connect to it. After disabling the Web Server as startup which stops php-cgi.exe from running the server runs flawless, like it always has. As soon as I run the web server all these odd issues start. I have a post over at Zend http://forums.zend.com/viewtopic.php?f=44&t=41043&p=95133 where I was told to update my Zend install. After doing so this issue has not gone away. Even running 1 php-cgi.exe (somehow 2 start anyway) the server begins to go silly. The first issue I find myself with running php-cgi.exe is that Windows Services, weather be stock or using FireDaemon begin to lag, slow start, crash, etc. If anyone can help me with this I would GREATLY appreciate it. At this time I am forced to look for a alternative to running PHP other than cgi as it simply takes out the whole box. On another note, I run this same version of Zend on a similar server with no issues. Starting to think its a IIS issue. (UPDATE) Installed newest version of PHP, separate from Zend, same issue.

• PHP Not Automatically Updating With ?reload=1

  - by user32007

  A friend built a ranking system on his site and I am trying to host in on mine via wordpress and godaddy. It updates for him but when I load it to my site, it works for 6 hours, but as soon as the reload is supposed to occur, it errors and I get a 500 timeout error. His page is at: jeremynoeljohnson .com/yakezieclub My page is currently at http://sweatingthebigstuff.com/yakezieclub but when you ?reload=1 it will give the error. Any idea why this might be happening? Any settings that I might need to change? Here is the top of the index.php file. I'm not sure which part of any of it is messing up. I literally uploaded the same code as him. Here's the reload part: $cachefile = "rankings.html"; $daycachefile = "rankings_history.xml"; $cachetime = (60 * 60) * 6; // every 6 hours, the cache refreshes $daycachetime = (60 * 60) * 24; // every 24 hours, the history will be written to - or whenever the page is requested after 24 hours has passed $writenewdata = false; if (!empty($_GET['reload'])) { if ($_GET['reload']== 1) { $cachetime = 1; } } if (!empty($_GET['reloadhistory'])) { if ($_GET['reloadhistory'] == 1) { $daycachetime = 1; $cachetime = 1; } } if (file_exists($daycachefile) && (time() - $daycachetime < filemtime($daycachefile))) { // Do nothing } else { $writenewdata = true; $cachetime = 1; } // Serve from the cache if it is younger than $cachetime if (file_exists($cachefile) && (time() - $cachetime < filemtime($cachefile))) { include($cachefile); echo ""; exit; } ob_start(); // start the output buffer ?

• Adventures in Drupal multisite config with mod_rewrite and clean urls

  - by moexu

  The university where I work is planning to offer Drupal hosting to staff/faculty who want a Drupal site. We've set up Drupal multisite with clean urls and it's mostly working except for some weird redirects. If you have two sites where one is a substring of the other then you'll randomly be redirected to the other site. I tracked the problem to how mod_rewrite does path matching, so with a config file like this: RewriteCond %{REQUEST_URI} ^/drupal RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /drupal/index.php?q=$1 [last,qsappend] RewriteCond %{REQUEST_URI} ^/drupaltest RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /drupaltest/index.php?q=$1 [last,qsappend] /drupaltest will match the /drupal line and all of the links on the /drupaltest page will be rewritten to point to /drupal. If you put the end of string character ($) at the end of each rewrite condition then it will always match on the correct site and the links will always be rewritten correctly. That breaks down as soon as a user logs in though because the query string is appended to the url so just the base url will no longer match. You can also fix the problem by ordering the sites in the config file so that the smallest substring will always be last. I suggested storing all of the sites in a table and then querying, sorting, and rewriting the config file every time a Drupal site is requested so that we could guarantee the order. The system administrator thought that was kludgy and didn't address the root problem. Disabling clean urls should also fix the problem but the users really want them so I'd prefer to keep them if possible. I think we could also fix it by using an .htaccess file in each site to handle the clean url rewriting but that also seems suboptimal since it will generate a higher load on the server and the server is intended to host the majority of the university's external facing web content. Is there some magic I can do with mod_rewrite to get it to work? Would another solution be better? Am I doing something the wrong way to begin with?

• Bacula stops writing to disk volume after 2GB

• Unexpected behaviour in a Lotus Notes programmable table

  - by Mark B

  I'm designing a workflow database in Lotus Notes 6.0.3 (soon upgrading to 8.5), and my OS is Windows XP. I have recently tried converting a tabbed table into a programmable one. This was so that I could control which tab was displayed to the user when it was opened, so that they were presented with the most appropriate one for that document's progress through the workflow. That part of it works! One of the tabs features a radio button that controls visibility of the next tab, and a pair of cascading dialogue boxes. One contains the static list "Person":"Team", and the other has a formula based on the first: view:=@If(PeerReview = "Team"; "GroupNames"; "GroupMembers"); @Unique(@DbColumn(""; ""; view; 1)) The dialogue boxes have the property "Refresh fields on keyword change" selected. The behaviour that I wasn't expecting is this. If the radio button is set to "Yes" and a value is selected in one of the dialogue boxes, the table opens the next tab. If the radio button is set to "No" and a value is selected in one of the dialogue boxes, the entire table is hidden. I can duplicate the latter by switching off the "Refresh fields on keyword change" property on the dialogue boxes and instead pressing F9 after selecting a value. I have no idea why the former occurs, though. The table is called "RFCInfo", and I have a field on the form called "$RFCInfo" which is editable, hidden from all users who aren't me and initially set by a Postopen script, which I can post if necessary - it's essentially a Select Case statement that looks at a particular item value and returns the name of the table row relating to that value. Can anyone offer any pointers?

• Transfer iptables rules to another server (almost) real time

  - by MrShunz

  I'm running 2 cPanel servers with ConfigServer Security & Firewall plugin. One of the functions of the plugin is to block via iptables (temporarily and/or permanently) IPs which fail various authentications (POP3/IMAP, SMTP, FTP, webmail, mod_security and such). Now, i'd like to push those IP blocks to the border router to drop packets as soon as possible (and doing so protecting the other machines on the network). Keep in mind that after N failed logins IP is blocked for 5 minutes, then re-allowed. If multiple bans occours in an hour IP is blocked permanently and should be unlocked "by hand". So I need a near realtime solution. What I'm looking for is a better way than firing some cronjobs both on cPanels and border router to: dump the rules to file transfer the file to border router (via scp/sftp) load the rules from the file in the border router I'm aware that I will need some scripts to parse and modify the rules as cPanels have one ethernet interface and some aliases while border router has two ehternet interfaces and some loopbacks. All machines involved use Linux. EDIT as per @pjmorse comment. The plugin consists of a bunch of perl and config files. The part I'm intrested in is a process which scans logfiles (lfd) and installs iptables rules (and sends an alert email). Fact is, it upgrades quite often (one or two times a week) and itself is 7000 lines of perl so I'm not comfortable on tampering with it.

• How to protect folder privacy against unethical network administrators? [closed]

  - by Trevor Trovalds

  I just need a technical solution for the sake of my group's shared passwords, projects, works, etc. safety. Our network has Active Directory with public/groups/users and NTFS permissions, under a Windows Server 2003 which will soon migrate to Windows Server 2008 R2. Our IT crowd is small, consisting of 2 DBAs, 4 designers, 6 developers (including me), 2 netadmins and (a lot of) tech supporters, everyone has local admin rights. Those 2 network admins weren't the ones who set the network up, they just took the lift recently when the previous ones quit. We usually find them laughing at private contents from users stored in the groups AD, sabotaging documents that don't match their personal tastes and, finally, this week we found out they stole a project we (developers and DBAs) were finishing and, long before, they presented it to the CEO as theirs without us knowing. I'm a systems analyst, and initially my group decided to store critical content, like shared passwords, inside encrypted .zip files. Unfortunately we couldn't do the same to the other hundreds of folders and files, which included the stolen project, because the zipping process would take too long for every update. We also tried an encrypted Subversion repository under SSL, but there are many dummies (~38 atm) involved in the projects that have trouble using TortoiseSVN when contributing, and very oftenly we had to fix messed up updates. Well, I think these two give the idea of what we've been trying to reach. So, is there a practical "individual" protection for our extensive data or my hope can already be euthanized? P.S.: Seriously, at the place where I live/work, political corruption gone the wildest, so denounce related options are likely impracticable. Yet both netadmins have strong "political bond" with the CEO and the President, hence their lousy behavior and our failed delation attempts.

• Laptop keyboard stopped functioning properly

  - by galdikas

  Basically today out of blue my laptop keyboard started acting up. For example I press "s" but I see "`s" on the screen. Some keys don't work at all. And the weird thing is it keeps changing, in a sense that for example in the morning I press "s" and I get "`s", then few hours later "s" works correctly.. but pressing some other key output multiple characters. Then sometimes it spontaneously will start outputting some character onto any input field that is available as soon as I click on it to gain focus. And it will just keep on going and going, as if I keep a button pressed (which I don't). At first I thought this was a virus, but I have a dual boot of Windows 7 and Ubuntu, and I get same problem on both. I even tried to boo live CD, and still had same problem. Anyone had this kind of problem? It's a Toshiba Satellite c660-258. It is around year old, but quite well kept. Never spilled anything on it, or dropped it. And my wireless USB keyboard works perfectly on it (appart from the spontaneous character inputs, which I can stop by hitting NUM LOCK key)

• Apache on CentOS 5.9 VM serves my optimized images corrupted (but my Mac doesn't)

  - by Robert K

  I'm using a Vagrant VM to mirror the client's environment as closely as I can. As part of our build process we do no optimization of assets early on; that comes as we're ready to take a site live. Needless to say, this issue is beginning to worry me as we need to take the site live very soon. I use ImageOptim to automate optimization of image assets, which runs a whole series of tools (Zopfli, PNGOUT, OptiPNG, AdvPNG, PNGCrush). I always set the optimizations to their maximum setting. After optimization, my PNGs start looking like this: What's weird is, if I serve the same file through my Mac's copy of Apache, not through Vagrant, the image loads fine. In fact, the only time it's ever corrupt like this is when the image is served from the Vagrant VM and its install of Drupal. All optimized JPEGs display only the first ~20% of the image. And PNGs, depending on the image, may show either a portion or the "progressive"-style corruption below. The browser itself makes no difference, the same browser will serve an uncorrupted image from my Mac's Apache instance and a corrupt image from the VM. When I disable all PNG optimizations except PNGCrush, and the removal of the PNG metadata, the image is served corrupted. I'm optimizing JPEG images with JPEGmini. The server is running CentOS 5.9, Apache 2.2.3-85, PHP 5.3.3, and Drupal 7. As best as I can tell the error lies somewhere within the VM, either with Apache or with (perhaps) the network stack. Seems like the tools that optimize the compression of the PNGs and JPEGs are what trigger this error. I've already determined that the .htaccess file isn't interfering with how the images load. What should I try to troubleshoot this?
