• Apache > 2.2.22 rewrite rule not working?

  - by EBAH

  since yesterday I'm trying to figure out how to fix the following: running phpipam (http://www.phpipam.net/) with WAMP (Windows environment). The problem I am facing is related with RewriteRule functionality, so forget phpipam for a moment and concentrate on few lines of code. Here is the directory structure of my test website that emulate the first steps phpipam does (you can download http://goo.gl/ksvuGc): C:\wamp\www\rewrite-tst\ C:\wamp\www\rewrite-tst\.htaccess C:\wamp\www\rewrite-tst\index.php C:\wamp\www\rewrite-tst\install C:\wamp\www\rewrite-tst\install\index.php It seems that the following rewrite rule in .htaccess doesn't work: C:\wamp\www\rewrite-tst\.htaccess # install RewriteRule ^install$ install/ [R] RewriteRule ^install/$ index.php?page=install When opening C:\wamp\www\rewrite-tst\index.php the first step check the URL for "install" argument. Since the URL is: http://localhost/rewrite-tst no arguments are supplied and the browser is redirected to: header("Location: /rewrite-tst/install/") At this point the browser opens the page: C:\wamp\www\rewrite-tst\install\index.php >> http://localhost/rewrite-tst/install Apache, thanks to C:\wamp\www\rewrite-tst.htaccess should intercept this URL and redirect to: http://localhost/rewrite-tst/index.php?page=install Here are my tries: Win Apache 2.2.22: works Win Apache 2.4.4: KO Win Apache 2.4.6: KO In the attached zip file you can also find two traces from apache RewriteLog which I can't understand very well. Why Apache 2.4 doesn't work on Windows? Is it possible that there's a bug on Windows version of Apache (2.4.4 and 2.4.6) or am I wrong someway? Thanks for your help!!! Evan -- UPDATE 12 oct 2013 Now I'm really confused! Working on Linux, Kubuntu 13.04. Linux Apache 2.2.22: works Linux Apache 2.4.6: KO I guess there's something wrong in my rules at this point, or some change happened from Apache 2.2 to 2.4 ...

• How To Fix Samba File Permission Issues in Mac OSX

  - by user1867768

  I've had this problem for a long time, here is the basics of it... I use a mixed environment of Windows 7/8 computers with Mac OSX Lion/Mountain Lion. Whenever a Windows computer creates a file on a SMB share on the Mac it no longer has group permissions, only the person who created or updated it can access it. My solution has been to go onto the Mac system and reset permissions for the entire directory structure then everyone can see it again. About the only thing on this that I can find was for OSX pre Snow Leopard that mentioned editing the SMB.CONF file to fix their particular problem (similar to mine, http://www.gladsheim.com/blog/2009/09/19/osx-leopard-and-samba-permissions/). The problem is that now Lion and Mountion Lion no longer have an SMB.CONF file (another web search pointed to the com.apple.smbd.plist (http://kidsreturn.org/?s=smb.conf) but it's an XML file now and I'm not clear on what should be done to THAT to fix the problem. So, short of me writing an Applescript to run every hour to fix permissions, does anyone know a solution to this very frustrating problem? Thank you in advance for any advice or solutions you can offer!

• Project and Business Document Organization

  - by dassouki

  How do you organize, maintain edits, revisions and the relationship between: Proposals Contracts Change Orders Deliverables Projects How do you organize your projects for re-usability? For example, is there a way to add tags to projects, to make them more accessible? What's a good data structure to dump all my files on an internet server for easy access? Presently, my work folder is setup as follows: (1)/work/ (2)/projects (3)/project_a (4)/final (which includes all final documents) (5)/contracts (5)/rfp_rfq (5)/change_orders (5)/communications (logs all emails, faxes, and meeting notes and minutes) (5)/financial (6)/paid (6)/unpaid (5)/reports (4)/old (include all documents that didn't make it into the project_a/final/ (3)/project_b (4) ... same as above ... (2)/references (3)/technical_references (3)/gov_regulations (3)/data_sources (3)/books (3)/topic_based (each area of my expertise has a folder with references in them) (2)/business_contacts (3)/contacts.xls (file contains all my contacts) (2)/banking (3)/banking.xls (contains a list of all paid and unpaid invoices as well as some cool stats) (3)/quicken (to do my taxes and yada yada) (4)/year (2)/education (courses I've taken (3)/webinars (3)/seminars (3)/online_courses (2)/publications (includes the publications I've made (3)/publication_id We're mostly 5 people working together part-time on this thing. Since this is a very structured approach, I find it really difficult to remember what I've done on previous projects and go back and forth easily. What are your suggestions on improving my processes? I'm open to closed and open source software (as long as the price isn't too high). I also want to implement a system where I can save most of the projects online to increase collaboration and efficiency and reduce bandwidth especially on document editing. Imagine emailing a document back and forth 5-10 times a day.

• What do I need in order to extract and combine text files from multiple ZIP files, via command line?

  - by Iszi

  I've got an interesting scripting challenge in front of me. I'm fairly certain there's a way to do it, but I feel like I'm probably lacking some particular tools and/or functional knowledge. There's some fifty-plus ZIP files that each contain, among other things, text files that need to be merged with one another. The structure is something like this: C:\Reports\FirstJob-1.zip |-MyName |-FirstJob |-1 |-[Some other folders] |-TXTReports |-English |-[Some other files] |-Report.txt C:\Reports\FirstJob-2.zip |-MyName |-FirstJob |-1 |-[Some other folders] |-TXTReports |-English |-[Some other files] |-Report.txt C:\Reports\SecondJob-1.zip |-MyName |-SecondJob |-1 |-[Some other folders] |-TXTReports |-English |-[Some other files] |-Report.txt If I had all the Report.txt files in one regular folder, and uniquely named, I could probably just write a FOR statement that targets *.txt and runs something like type filename.txt >> Consolidated.txt on each. However, these all have the same file name and are embedded deep within separate ZIP files. The potentially useful tools I currently have at my disposal are Windows XP Professional SP3, PowerShell, and WinZip. I'd rather not download or install anything else, but I do understand that third-party tools (or additional tools from Microsoft or WinZip) may be necessary. Whatever tools I use should run natively in Windows. I really don't want to have to mess with Cygwin or other emulators on this system. At the very least, I need a tool that will allow me to analyze and manipulate ZIP files from the command line. Also, are there any other particular complications to this that I've not yet thought of?

• How to create an MST for silent install using Orca?

  - by Sanarothe

  Hi. I'm trying to deploy 7zip via GPO; I assigned the original MSI, but the package installation simply doesn't take place. What I've gathered is that I need to create an MST. In the spirit of trying to learn as much as possible about it, I've opted to use Orca rather than a third-party automagic tool, but I'm at a loss as to which fields to edit. So far the only change that I've made is to give the license accepted checkbox a value of "1" instead of pointing to another key that, still, just gave it a value of "1." So, to give this some structure, How does (Or what criteria should I consider) creating a MST make the install noninteractive/silent? Do you have to manually reconfigure the MSI to simply not perform the GUI aspects? Or do I have to execute the program in silent mode after defining the variables the the installer requests? (Though, of course, it seems that would defeat the purpose of the MST) How do I determine which fields I need to edit? I've loaded the installer and it takes three inputs: License acceptance, feature set and installation location. I want all of the default values: I'm just trying to deploy it at all, not customize the installation. I BELIEVE that I should be messing with some values in the Registry table, but I really don't know. If I'm not asking the right questions, can someone point me to a THOROUGH resource or documentation for this process? I've already gone over the technet articles on basic Orca use and deployment, but I couldn't really find anything on creating MST that didn't involve a third party program in which one runs a 'dummy' installer to get the before and after snapshots. Thank you very much, Cameron UPDATE: After spending the day troubleshooting, I finally got my server to send out 7zip, but not until I had also assigned firefox. Not sure why it didn't want to send out 7zip by itself, but I also had some domain naming problems. Thanks for the input (GPResult helped enormously.)

• htaccess not properly rewriting urls

  - by Cameron Ball

  This is a bit of a weird one. I'm doing some work on a server, and I need rewrite rules for directories that actually exist (in some cases, they are more than one level deep) At the moment my .htaccess looks like this: RewriteEngine on RewriteRule ^simfiles/([-\ a-zA-Z0-9:/]+)$ http://mydomain.com/?portal=simfiles&folder=$1 [L] And this is working OK, for example, a url like: mydomain.com/sifmiles/my-files Will get redirected to mydomain.com/?portal=simfiles&folder=my-files Or in the case of a directory structure that is deeper than one level: mydomain.com/sifmiles/my-files/more-of-my-files Will get redirected to mydomain.com/?portal=simfiles&folder=my-files/more-of-my-files I wrote the regex so that it won't match things with a . in the path, because there are css and js files which reside in simfiles/somedirectory, and if I redirect everything then these cannot be loaded. I tried a configuration like this: RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^simfiles/([-\ a-zA-Z0-9:/\.]+)$ http://mydomain.com/?portal=simfiles&folder=$1 [L] But that doesn't work, things still don't load properly. So my first question is, how can I achieve this "properly"? I don't like my solution because it means redirects won't occur if the folder has a . in its name. My second problem, is that while the redirection is happening properly, the url becomes: http://mydomain.com/?portal=simfiles&folder=my-files I want the URL to remain clean, like: http://mydomain.com/sifmiles/my-files How can I achieve this?

• 1000Base-X layer 2/MAC address details

  - by user69971

  A layer 2 Ethernet frame is sent with a source and destination MAC address. Given a 100Base-TX (copper) trunk between two Cisco switches, I can do a "show interface fa 0/0" on S1 to see the MAC address assigned to the trunking interface, then go to Switch2 and do a "show mac address-table" and find the MAC address of the S1 fa 0/0 interface as a dynamically learned MAC in the table. Given a similar setup with a 1000Base-X (fiber GBIC) trunk, the MAC address shown in "show interface gi 0/0" on S1 does not show up in the MAC address-table of S2. Everything I can find online indicates that 1000Base-X uses largely the same layer 2 format as copper connections. There's some slight alterations - minimum frame size is slightly larger - but the fundamentals of the frame structure appear to be the same, including transmission with a source and destination L2 address. Why doesn't the address of gi 0/0 show up in the MAC address table of the connection switch? The only thing which seems to make sense would be that the GBIC has its own MAC address, almost as if its acting as a mini 2-port switch or hub, with the switch-assigned MAC address showing up on the interface connection and a different MAC address assigned to the fiber side. If this is the case, is there any way to see the GBIC MAC address on the switch? (I've tried to look up the details in IEEE 802.3z but it doesn't seem to be available without an IEEE membership or purchasing the standard. I find the base 802.3 PDFs for download, but not 802.3z.)

• Configuring suExec to work with Apache and PHP via FastCGI

  - by RandomPsychology

  I have installed ISPConfig 3 on an Ubuntu VPS and configured it for Apache + PHP via FastCGI and suexec. I am able to upload PHP apps (e.g. Wordpress) and run them normally w/ suexec. However, for some reason the PHP scripts cannot write data to disk. For instance, trying to upgrade a plugin via Wordpress' web interface causes it to fail with the error "Could not create directory /path/to/wp-content/upgrade/plugin.tmp." Trying to upload media and other assets also fails via the web. I've checked owner/group on the directory structure and it looks good. The suExec log also seems to be normal and I don't see any indicative errors in the web server logs. I can also confirm that changing the owner/group on the directories does result in the expected error in suexec.log. Additionally, I have the directory permissions set to u=rw,g=r,o= and I've also tried setting g=rw. None of this results in my scripts being able to write to the directories. What am I doing wrong?

• Using dropbox / symbolic link combo successfully

  - by wim

  In the past I have kept some files on dropbox by copying them into my ~/Dropbox folder on Ubuntu. I don't want to move the original files into Dropbox synch folder or muck around with my directory structure. Then I have found I was using dropbox more and more, and wasting a lot of space this way by duplication of data. I use a small SSD locally for OS, any other data is kept on mounted shares from my NAS. I found I could successfully get files up to the cloud by using symbolic links like: ln -s /some/mounted/share/dir ~/Dropbox/dir And dropbox would carry on and sync those files remotely whilst only using up the space of the symbolic link locally. This worked well for me for a few weeks, until I turned on my laptop one day and saw '421 files have been removed from your dropbox' notification. They were still there in the original mounted share, but the symbolic links I'd made were completely gone for some reason. What did I do wrong? It is possible the share could have become unmounted, but I didn't expect this would cause all my files to be deleted from the cloud could it? How can I 'share' files on my dropbox in this way without the danger of the originals being modified from remotely?

• Cannot open Pivot Table source file

  - by Ken

  Excel Pivot table error is: Cannot open Pivot Table source file C:\Users\UserName\AppData\Roaming\Microsoft\Excel\DatabaseName (version1).TableName I’ve seen other questions and answers with the same topic, but I think this is different. I believe I know why the error is occurring: Excel closed unexpectantly and did autosave with (version1) attached to the original file name and saved it in the C:\User etc. above , which is the default recovery location. I opened the recovered file in Excel, saved it as version1 on the server where the original file was located, deleted the original file, and renamed the version1 to the original name. When I go to PivotTable Tools? Options? Change Data Source, it shows only the Table and Range, which are correct, but it does not show the file name or path. The version1 and the renamed file both had the same structure, so the same source table was in both, by they were different files. How do I change the source file from what it is looking for to my renamed file? PS- The (version1) file that it says it is looking for is not in the autosave location, i.e. it is not at the path where it says it is looking in. Thank you for any help Ken

• Apache randomly loses permission to see files.

  - by arbales

  I have a server (Leopard Server, not my choice) running Apache and MySQL. Several months ago, the server began to raise "Forbidden" errors at random intervals, preventing access to a PHP application. This behavior randomly ceased. Now, several days ago I installed Passenger and deployed a Sintra/Rack application. The application runs as a user acarneg (for example) from /Library/WebServer/Documents/presto/current/public, acarneg owns the entire structure. The _www user has access to the directory via ACL chmod +a "_www allow read,write,...". Everything works great! But after a randomish interval, often ~12 or ~24 hours, Passenger throws an error that also prevents the PHP application from running. Passenger Error #2. Cannot stat file config.ru. Permission denied. But the permissions haven't changed (confirmed) and all one has to do to resolve the error is sudo apachectl graceful. If the permissions aren't changing and Apache doesn't seem to have a legit problem, what is causing this mess? Why did it stop before, and why has it resumed!?!?!? Thanks for the help!

• EC2 Configuration

  - by user123683

  I am trying to create a server structure for my EC2 account. The design I have chosen consists of 2 instances running in different availability zones, elastic load balancer, an auto-scaling group with cloudwatch monitoring configured and a security group defining rules for access to the instances. This setup is to support an online web application written in PHP. I am trying to decide what is a better policy: Store MySQL DB on a separate Instance Store MySQL DB on an attached EBS volume (from what i know auto-scaling will not replicate the attached EBS volume but will generate new instances from a chosen AMI - is this view correct?) Regards the AMI I plan to use a basic Amazon linux 64 bit AMI, and install bastille (maybe OSSEC) but I am looking to also use an encrypted file system. Are there any issues using an encrypted file system and communication between the DB and webapp i neeed to be aware of? Are there any comms issues using the encrypted filesystem on the instance housing the webapp I was going to launch a second instance or attach a second volume in the second availability zone to act as a standby for the database - I'm just looking for some suggestions about how to get the two DB's to talk - will this be a big task Regards updates for security is it best to create a recent snapshot and just relaunch and allow Amazon to install updates on launch or is the yum update mechanism a suitable alternative - is it better practice to relaunch instead of updates being installed which force a restart. I plan to create two AMI snapshots one for the app server and one for the DB each with the same security measures in place - is this a reasonable - I just figure it is a better policy than having additional applications that are unnecessary included in a AMI that I intend on using. My plan for backup is to create periodic snapshots of the webapp and DB instances (if I use an additional EBS volume instead of separate instances my understanding is that the EBS volume will persist in S3 storage in the event of an unexpected termination and I can create snapshots of the volume backup purposes). Thanks in advance for suggestions and advice. I am new to EC2 and I may have described unnecessary overkill but I want to try implement what can be considered a best practice solution so all advice is appreciated.

• How do you verify a restore?

  - by Nic

  What tool(s) would you use to verify that a restored file structure is whole and complete? My environment is a Windows Server 2008 file server. (We use tape for backup, but that is inconsequential.) I am specifically looking for a tool that will: Record the names of all files and folders below a specified directory Optionally calculate checksums of each file encountered Save this index in a human-readable format Compare the index against restored data and show differences Some background: I recently had to replace the disks in our file server. The upgrade was scheduled to start 36 hours after the most recent full backup, so I created a differential backup. However, it turns out that one of our applications was clearing the archive bit on files saved to the server, so these were not included in the differential backup. I was unaware of this until my users reported some files as missing. Aside from this, are there any other common methods for validating the integrity of a restore? I am frequently told that testing backups by restoring them is the only way to know that backups are working, but how do you deal with the case where it works 99% correctly and the other 1% silently fails?

• Nginx's speed, and how to replicate it [migrated]

  - by Mediocre Gopher

  I'm interested in this from more than an academic standpoint rather than a practical standpoint; I don't plan on creating a production webserver to compete with nginx. What I'm wondering is how exactly nginx is so fast. The top google response for this is this thread, but it merely links to a cryptic slideshow and a general covering of different io strategies. All other results seem to simply describe how fast nginx is, rather then the reason. I tried building a simple erlang server to try to compete with nginx, but to no avail; nginx won out. All my server does is spawn a new process for each request, uses that process to read the file to a socket, then closes the file and kills the thread. It's not complicated, but given erlang's lightweight processes and underlying aio structure I thought it would compete, but nginx still wins out by a consistent 300 ms average under a heavy stress test. What is nginx doing that my simple server isn't? My first thought would be keeping files in main memory instead of tossing them between requests, but the filesystem cache does this already so I didn't think it would make that great of difference. Am I wrong? Or is there something else that I'm missing?

• Advice needed for a home network setup (hardware & software) to handle many clients and potentially heavy traffic

  - by posdef

  I have recently decided to re-structure the home network of our flatshare here. Here's a quick outline of the situation. I envision to have the following 4 devices connected to the router via cable: Xbox 360 IP phone Printer QNAP server (Web, File and Multimedia) We are three people living here, so on top of that there will be to 5-6 computers/mobile devices connecting as wireless clients. My goal is to be able to transfer files (when needed) between the computer and the Multimedia server, which I can reach via 360 and play on the TV. I also would like to keep a high level of security; right now I have the encryption on WPA2 and MAC filtering. I don't believe the web server will get heavy traffic, though I would like to have it responsive. Likewise, I don't have a habit of downloading via torrent etc, but I greatly appreciate my network being responsive and fast, especially when I am browsing or streaming high quality media. Now my questions are: is this setup feasible? smart? efficient? can this be improved somehow? my current router (D-Link DI624) and the previous one (DI-524) used to have spontaneous drops in network, which I find highly irritating. I don't believe in my router, especially now that it completely crashed when I was test-running the setup by transferring a large media file to server while xbox was playing music from the server, and two computers browsing the net. Do I need to get new hardware, if so, any recommendations for a reliable and fast router?

• How to restrict zone transfers to specific authorized servers only

  - by JonoB

  I recently failed a PCI compliance scan because of the following: This DNS server allows unrestricted zone transfers. Attackers may be able to use this information to gain knowledge on the structure of your networks to aid in device discovery prior to an actual attack. And the suggested solution is as follows: Reconfigure this DNS server to restrict zone transfers to specific authorized servers only. I am running a dedicated Linux Centos server. My understanding is that I have to edit the /etc/named.conf file, which I have done and the the relevant part is as follows: options { acl "trusted" { 127.0.0.1; xxx.xxx.xxx.001; //this is one of the server's ip's xxx.xxx.xxx.002; //this is another server's ip }; allow-recursion { trusted; }; allow-notify { trusted; }; allow-transfer { trusted; }; }; I then restarted the named service /etc/rc.d/init.d/named restart and requested a re-scan, which failed again for the same reason. Am I missing something obvious here?

• Data recovery on a corrupted 3TB disk

  - by Mark K Cowan

  Short version I probably need software to run a deep-scan recovery (ideally on Linux) to find files on NTFS filesystem. The file data is intact, but the references are no longer present. Analogous to recovering data from a "quick-formatted" partition. Hopefully there is a smarter way available than deep-scan, one which would recover filenames and possibly paths. Long version I have a 3TB disk containing a load of backups. Windows 7 SP1 refused to detect the disk when plugged in directly via SATA, so I put it on a USB/SATA adaptor which seemed to work at first. The SATA/USB adaptor probably does not support disks over 2.2TB though. Windows first asked me if I wanted to 'format' the disk, then later showed me most of the contents but some folder were inaccessible. I stupidly decided to run a CHKDSK on my backup disk, which made the folders accessible but also left them empty. I connected this disk via SATA to my main PC (Arch Linux). I tried: testdisk ntfsundelete ntfsfix --no-action (to look for diagnostically relevant faults, disk was "OK" though) to no avail as the files references in the tables had presumably been zeroed out by CHKDSK, rather than using a typical journal'd deletion). If it is useful at all, a majority of the files that I want to recover are JPEG, Photoshop PSD, and MPEG-3/MPEG-4/AVI/MKV files. If worst comes to worst, I'll just design my own sector scanner and use some simple heuristic-driven analysis to recover raw binary blocks of data from the disk which appears to match the structures of the above file types. I am unfamiliar with the exact workings of NTFS but used to be proficient at recovering FAT32 systems with just a hex-editor, so I can provide any useful diagnostic information if you let me know how to find it! My priorities in ascending order of importance for choosing the accepted answer: Restores directory structure Recovers many filenames in addition to the file data Is free / very cheap Runs on Linux Recovers a majority of file data The last point is the most important, but the more of the higher points you match the more rep you'll probably get :)

• Calendar sharing between unrelated Domains

  - by vlannoob

  I have a 'request' from one of the 'big guys' that has me scratching my head a bit. He is one of our Executives that also is a board member of several other organistations, so he floats around between 4 different unrelated companies, each with their own domains, Exchange setup etc. He has domain accounts in each organisation. He has an iPad with multiple Exchange accounts so he can see all his calendars which works Ok for him - Apple calendaring bugs/flaws aside. What he wants is the ability for 'reception staff' at each organisation to 'see' all his calendars as they are booking things for him in their respective organisations calendars without it conflicting with bookings made in his calendars by other organisations......you with me?? So for example: Company A books a meeting into his Comapny A calendar at 9am Monday and Company B books him a meeting in his Company B Calendar at 9:15am Monday on the other side of town and of course Company C has him booked in all day Monday on their Company C calendar. He gets all those on his iPad but he would like either a 'global' calendar all can see and book into or the ability for receptionists at Company's A,B and C to see all the Calendars to avoid these kind of conflicts. I told him to 'go away' straight off the bat, I don't control anything to do with the other companies or know their infrastructure. And quite frankly I don't want any part of it...but he's whining and he's high enough up the food chain that I can't ignore him forever. I'm open to suggestions. Is there any third party software/services that can facilitiate this kind of setup? I really don't want to be creating users in my AD structure to people not ion our organisation so they can get access to his calendar and I am sure there sysadmins feel the same. As usual - any advice is greatly appreciated ;)

• kickstart ks.cfg: Where should 'url' point?

  - by Stefan Lasiewski

  I have a kickstart file (ks.cfg) on a floppy (Old style). I am trying to install CentOS 5.4. The top of my ks.cfg says this: install # Install from local cdrom or over the network. #cdrom url --url http://kickstart.example.org/pub/centos/5.4/ On the Apache server side, this command is failing with these 404s: kickstart.example.org 192.168.16.180 - - [01/Jun/2010:17:24:30 -0700] "GET /pub/centos/5.4///disc1/.discinfo HTTP/1.1" 404 314 "-" "urlgrabber/3.1.0" kickstart.example.org 192.168.16.180 - - [01/Jun/2010:17:24:43 -0700] "GET /pub/centos/5.4/repodata/repomd.xml HTTP/1.1" 404 316 "-" "urlgrabber/3.1.0 yum/3.2.22" It seems that the value of my url doesn't match the directory structure on the server. I swear this worked a few months ago. Someone else maintains the Yum repository, and they say nothing has changed. What should the value of url URL be? Should this only include the OS (/pub/centos/5.4/), or should it include the architecture (/pub/centos/5.4/os/x86_64 )? I see that Kickstart is trying to grab a file called 'repomd.xml', but why is it looking in '/pub/centos/5.4/repodata/repomd.xml', when these files actually exist at '/pub/centos/5.4/os/x86_64/repodata/repomd.xml' and other locations at '/pub/centos/5.4/*/$ARCH/repodata/repomd.xml'? I don't see this documented or explained well in the [RedHat 5 Installation Guide1]

• Firebird database corruption causes

  - by Rytis

  I am running several different Firebird versions (2.0, 2.1) on multiple entry level Windows-based servers with wildly varying hardware. The only matching thing between them is that they are running same home built application with the same database structure. Lately I've been seeing massive slowdowns on multiple servers. Turns out that database gets corrupted, so each time it breaks, I get to mend, backup and restore the database, and it all is fine for some time (1-2 weeks), and then it repeats once again. Thankfully, I haven't seen any data loss or damage... yet. The thing is that every such downtime results in lost productivity, and often quite some driving for me as some of the databases are in remote locations. I've been trying to find out what's causing the corruption, but I haven't been able to. The fact that it's running on different hardware hints that it should not be a hardware based problem. If we rule out hardware issues, I have a bad feeling that it's a bug in Firebird as I'm not doing anything fancy via SQL. Do you have any idea how to find out exactly what's causing the corruption and hopefully fix the problem?

• Backup and Archive Strategy Question

  - by OneNerd

  I am having trouble finding a backup strategy for our code assets that 'just works' without any manual intervention. Goal is to have an off-site backup (a synchronized one) so that when we check-in files, create builds, etc. to the network drive, the entire folder structure is automatically synchronized and backed-up (in real time, or 1x per day) at some off-site location so if our office blows up, we don't lose all of our data. I have looked into some online backup services, but have not yet had any success. Some are quirky/buggy, others limit file size and/or kinds of files (which doesn't work well for developer files). Everything gets checked in and saved to a single server (on a Raid Mirror), so we just need to have a folder on that server backed up/synchronized to some off-site location. So my question is this. What are you using for your off-site backup strategy. What software, system, or service? Is there a be-all/end-all system of backing up your code assets that I just haven't found yet? Thanks

• SQL 2008 Replication corrupt data problem

  - by Jonathan K

  We took a SQL 2000 database. Took a lightspeed backup. Restored on SQL 2008 active/passive cluster. Then setup replication to replicate the data back to SQL 2000. So 2008 is the publisher/distributor, and 2000 is doing a pull subscription. Everything works well, execpt we occassionally get corrupt data in varchar/text fields on the subscriber. So for example we have a table with 4500 records. When we run this statement: update MedstaffProvider set Notes = 'Cell Phone: 360.123.4567 Answering Service: 360.123.9876' where LastName = 'smith' The record in the 2008 database is updated as expected. But in the subsriber datbase we'll get gibberish in the notes field: óPÌ[1] T $Oé[1] ð²ñ. K Here's what we know: This is repeatable, meaning we can run that same query all day long and get the same gibberish. If you alter update statement slightly the data gets replicated just fine. The collation on both databases is the same. So far we've only detected the problem with text/varchar fields. (The notes field above is text). Only one or two records in a table are impacted. The table structure looks identical in both 2000/2008. We haven't made any changes. We have found one solution that fixes the problem. Basically if we recreate the table in 2008 (say as MedStaffProvider2) and then insert all the data. Drop the original table. Rename the table to it's original name. Setup replication again. And run the exact same update statement it works as expected. Does anyone have any idea what might be happening here? Or are there any other techniques we can use to troubleshoot this? I've found a solution for this, but would really like to undertsand why this is happening.

• Subversion all or nothing access to repo tree

  - by Glader

  I'm having some problems setting up access to my Subversion repositories on a Linux server. The problem is that I can only seem to get an all-or-nothing structure going. Either everyone gets read access to everything or noone gets read or write access to anything. The setup: SVN repos are located in /www/svn/repoA,repoB,repoC... Repositories are served by Apache, with Locations defined in etc/httpd/conf.d/subversion.conf as: <Location /svn/repoA> DAV svn SVNPath /var/www/svn/repoA AuthType Basic AuthName "svn repo" AuthUserFile /var/www/svn/svn-auth.conf AuthzSVNAccessFile /var/www/svn/svn-access.conf Require valid-user </Location> <Location /svn/repoB> DAV svn SVNPath /var/www/svn/repoB AuthType Basic AuthName "svn repo" AuthUserFile /var/www/svn/svn-auth.conf AuthzSVNAccessFile /var/www/svn/svn-access.conf Require valid-user </Location> ... svn-access.conf is set up as: [/] * = [/repoA] * = userA = rw [/repoB] * = userB = rw But checking out URL/svn/repoA as userA results in Access Forbidded. Changing it to [/] * = userA = r [/repoA] * = userA = rw [/repoB] * = userB = rw gives userA read access to ALL repositories (including repoB) but only read access to repoA! so in order for userA to get read-write access to repoB i need to add [/] userA = rw which is mental. I also tried changing Require valid-user to Require user userA for repoA in subversion.conf, but that only gave me read access to it. I need a way to default deny everyone access to every repository, giving read/write access only when explicitly defined. Can anyone tell me what I'm doing wrong here? I have spent a couple of hours testing and googling but come up empty, so now I'm doing the post of shame.
