• Are "strings.xml" string arrays always parsed/deserialized in the same order?

  - by PhilaPhan80

  Can I count on string arrays within the "strings.xml" resource file to be parsed/deserialized in the same order every time? If anyone can cite any documentation that clearly spells out this guarantee, I'd appreciate it. Or, at the very least, offer a significant amount of experience with this topic. Also, is this a best practice or am I missing a simpler solution? Note: This will be a small list, so I'm not looking to implement a more complicated database or custom XML solution unless I absolutely have to. <!--KEYS (ALWAYS CORRESPONDS TO LIST BELOW ??)--> <string-array name="keys"> <item>1</item> <item>2</item> <item>3</item> </string-array> <!--VALUES (ALWAYS CORRESPONDS TO LIST ABOVE ??)--> <string-array name="values"> <item>one</item> <item>two</item> <item>three</item> </string-array>

• setContentView taking long time (10-15 seconds) to execute

  - by Paul

  I have a large activity that contains 100 or more buttons. But it's working fine once loaded. Problem however is loading. From clicking its launch icon to getting the first view it takes 10-12 seconds. Until the first view, it shows gray title bar in black background. At least, I want to show a simple progress bar or dialog while its loading. But it seems like you cannot show anything before setContentView executed. I think I have tried everything I could without any success. If you can give me any hint or idea, I would be thankful. UPDATE: I found a dramatic resolution. It takes now a second to load the view. I didn't use splash, thread or async task at all - BTW, don't try to use thread or async on UI because Android UI is not thread-safe. Problem was that those buttons were based on a custom class that requires initialization to load same resource. - so 100 or more file operations were happening on setContentView. Making them a just single loading solved my problem.

• 'table' undeclared (first use this in a function)

  - by user2318083

  So I'm not sure why this isn't working, I'm creating a new table and setting it to the variable 'table' Is there something I'm doing wrong? This is the error I get when trying to run it: src/simpleshell.c:19:3: error: ‘table’ undeclared (first use in this function) src/simpleshell.c:19:3: note: each undeclared identifier is reported only once for each function it appears in My code is as follows: #include "parser.h" #include "hash_table.h" #include "variables.h" #include "shell.h" #include <stdio.h> int main(void) { char input[MAXINPUTLINE]; table = Table_create(); signal_c_init(); printf("\nhlsh$ "); while(fgets(input, sizeof(input), stdin)){ stripcrlf(input); parse(input); printf("\nhlsh$ "); } Table_free(table); return 0; } Then this is my create a table in the hash_table file: struct Table *Table_create(void){ struct Table *t; t = (struct Table*)calloc(1, sizeof(struct Table)); return t; } From the hash_table.c: #include "hash_table.h" #include "parser.h" #include "shell.h" #include "variables.h" #include <stdio.h> #include <sys/resource.h> #include <sys/wait.h> #include <sys/types.h> #include <stdlib.h> #include <string.h> #include <unistd.h> #include <pwd.h> #include <fcntl.h> #include <limits.h> #include <signal.h> struct Table *table; unsigned int hash(const char *x){ int i; unsigned int h = 0U; for (i=0; x[i]!='\0'; i++){ h = h * 65599 + (unsigned char)x[i]; } return h % 1024; }

• Remove .img css from prepended div

  - by Ivan Schrecklich

  OK as the title says I've got a div which is prepended and dynamically loaded. The problem I have is that I can't split the css on this one as it parses also whole strings. The usage is like that: I've got a @username somewhere in the string. If the user hovers it a div with informations will get prepended to the current username. Now there is the problem that I've allowed users to post images in this text also. As the autolinker is flexible it doesn't know the image sizes and restrictions and I want to leave it like that! So I define css classes which look like that: .minpost img{ max-height: 30px; max-width: 30px; } Of course I don't need to mention that this attribute is also inherited by the prepended div. And that I don't want to! nifty little tricks like !important won't work for me. So I am asking you guys. If you need further informations just ask?!

• SCVMM 2012 R2 - Installing Virtual Switch Fails with Error 2916

  - by Brian M.

  So I've been attempting to teach myself SCVMM 2012 and Hyper-V Server 2012 R2, and I seem to have hit a snag. I've connected my Hyper-V Host to SCVMM 2012 successfully, and created a logical network, logical switch, and uplink port profile (which I essentially blew through with the default settings). However when I attempt to create a virtual switch on my Hyper-V host, I run into an issue. The job will use my logical network settings I created to configure the virtual switch, but when it tries to apply it to the host, it stalls and eventually fails with the following error: Error (2916) VMM is unable to complete the request. The connection to the agent vmhost1.test.loc was lost. WinRM: URL: [h**p://vmhost1.test.loc:5985], Verb: [GET], Resource: [h**p://schemas.microsoft.com/wbem/wsman/1/wmi/root/virtualization/v2/Msvm_ConcreteJob?InstanceID=2F401A71-14A2-4636-9B3E-10C0EE942D33] Unknown error (0x80338126) Recommended Action Ensure that the Windows Remote Management (WinRM) service and the VMM agent are installed and running and that a firewall is not blocking HTTP/HTTPS traffic. Ensure that VMM server is able to communicate with econ-hyperv2.econ.loc over WinRM by successfully running the following command: winrm id –r:vmhost1.test.loc This problem can also be caused by a Windows Management Instrumentation (WMI) service crash. If the server is running Windows Server 2008 R2, ensure that KB 982293 (h**p://support.microsoft.com/kb/982293) is installed on it. If the error persists, restart vmhost1.test.loc and then try the operation again. Refer to h**p://support.microsoft.com/kb/2742275 for more details. I restarted the server, and upon booting am greeted with a message stating "No active network adapters found." I load up powershell and run "Get-NetAdapter -IncludeHidden" to see what's going on, and get the following: Name InterfaceDescription ifIndex Status ---- -------------------- ------- ----- Local Area Connection* 5 WAN Miniport (PPPOE) 6 Di...

Does anybody have any ideas? Much appreciated!

• Nginx1.6.1: Installing from source not running corectly

• Partitioning recommendations for a Proxmox VM Server (OpenVZ)

  - by luison

  We are new to virtualization and we are planning to turn our online server into a virualized one, mainly for maintenance, backup and recovery improvements. Initially we would only have one real virtual system with load plus 1-3 copys for testing and recovering and maybe a small centralized syslog virtual machine. We would like, if possible the host machine to include an iptables plus rsync to back up to other machines and some other global security systems. Due to this and the offerings of our hosting supplier we are mainly considering Proxmox for its simplicity (we like the idea of its web admin panel) and as I also understand that the container approach of OpenVMZ systems may fit well resource wise with our setup. The base system comes with debian so we can personalise it to our requirements. Proxmox installations default installs an LVM partition for the VMs. Our doubts are with the fact of what would be the best partition structure for this considering that: we would like to have a mirror of the root partition we could boot from if required (our provider supports booting the system from another partition via control panel) we ideally would like to have a partition that could be shared among the VM systems. We still don't know if this is possible directly with OpenVMZ containers, otherwise we are considering doing this by sharing it via NFS on the host machine. we want to use the backup system available on the proxmox host administrator to programme VMs backups and then rsync it to another machine. With this based on a Linux Raid of aprox (750Gb) we are considering something like: ext3_1/ - (20Gb) ext3_2/bak_root - (20Gb) mostly unmounted, root partition sync LVM_1 /var/lib/vz - (390Gb) partition for virtual images LVM_2 /shared_data - (30Gb) LVM_3 /backups - (300Gb) where all backups would be allocated Our initial tests with Proxmox seem to have issues with snapshots backups like this, perhaps caused by the fact that they can not be done to another LVM partition (error: command 'lvcreate --size 1024M --snapshot --name vzsnap-ns204084.XXX.net-0 /dev/pve/LV' failed with exit code 5) in which case we might have to use a standart ext3 partition (but unsure if we can do this with the 4 primary partition limitations). Does this makes more or less sense? Would it be mad to for example write VMs /var/logs to a NFS mounted partition (on the host system)? Are their any other easier ways to mount host system partitions (or folders) to the VMs?

• windows firewall broken on server 2008

  - by Chloraphil

  This evening I tried to rdp into my server 2008 box and was unable to. After poking around some I discovered that something is awry with my Windows Firewall. I did install 5 windows updates remotely earlier today but rolled those back in an attempt to see if that fixed the problem but had no luck. Symptoms: cannot rdp to machine (including from itself) cannot ping machine cannot connect to file share on machine error message when attempting to open "windows firewall with advanced security" snap-in (there was an error opening the windows firewall with advanced security snap-in ... The Windows Firewall with Advanced Security snap-in failed to load. Restart the windows firewall service on the computer that you are managing. Error code: 0x6D9. When I opened the "user-friendly" Windows Firewall it failed to load most of the gui elements, meaning, the title bar with close, minimize, and maximize buttons is present, the rest of the window has a white background with a yellow rectangle with rounded corners and a yellow triangle w/ an exclamation point is in the upper right. hope that made sense "Windows Firewall" does not appear in the list of services I ran a virus scan that found nothing. How do I fix the firewall and hopefully restore the ability to rdp? EDIT: Added at fission's request: c:\sc query mpsdrv SERVICE_NAME: mpsdrv TYPE : 1 KERNEL_DRIVER STATE : 4 RUNNING (STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN) WIN32_EXIT_CODE : 0 (0x0) SERVICE_EXIT_CODE : 0 (0x0) CHECKPOINT : 0x0 WAIT_HINT : 0x0 c:\sc query mpssvc SERVICE_NAME: mpssvc TYPE : 20 WIN32_SHARE_PROCESS STATE : 1 STOPPED WIN32_EXIT_CODE : 1068 (0x42c) SERVICE_EXIT_CODE : 0 (0x0) CHECKPOINT : 0x0 WAIT_HINT : 0x0 Those two registry keys do exist: HKLM\SYSTEM\CurrentControlSet\Services\mpsdrv & HKLM\SYSTEM\CurrentControlSet\Services\MpsSvc ! The problem seems to be with the Base Filtering Engine, when I try to start it I get the following error: Windows could not start the Base Filtering Engine service on MYCOMPUTER. Error 15100: The resource loader failed to find MUI file. EDIT2: I ran sfc /scannow and i found about 100 occurrences of "[SR] Cannot repair member file"... including several related to the firewall (ex: [l:32{16}]"Firewall.cpl.mui" of Networking-MPSSVC.Resources...). One of them mentioned wordpad.exe, which I tried to open, and it failed. I found here mentions of mounting the install.wim on the install media to copy the affected files over. I am downloading the appropriate AIK and will continue tomorrow evening.

• vSphere Client vCenter Template Customization Specification Using Windows Sysprep Unattended Answer XML File

  - by Brian

  I'm trying to setup a vSphere Client vCenter v5.0.0 Build 455964 Template Customization Specification using a Windows Sysprep unattended answer XML file for Win2008R2. However I didn't know how Sysprep worked before attempting this so it was a time-consuming nightmare (even after reviewing VMware vSphere ESXi 5's documentation)! I think I've figure out what I'm supposed to be doing, but it's still not working. The biggest problem at this point is that vSphere Client vCenter Customization Specification IP address information is not sticking when I load a Sysprep XML file with just 1 basic setting! This can only be a bug. Here is the process I'm using: PROCESS for Windows - vSphere Client Install Windows OS install VM Tools customize Windows (GPOs can be used to do this after deployment) install Applications (GPOs can be used to do this after deployment too) shutdown the VM convert the VM to a template create a custom Windows Sysprep XML answer file with desired customizations View Management Customization Specifications Manager create "New" Specification for "Target Virtual Machine OS" select Windows check "Use Custom Sysprep Answer File" (ADDS: Custom Sysprep File. KEEPS: Network (IP), Operating System Options (SID, Sysprep /generalize). REPLACES: Registration Information of Owner Name & Organization, Computer Name, Windows License (Key), Administrator Password, Time Zone, Run Once, Workgroup or Domain) name it as "VMwareCS-OS####R#x32/64w/Sysprep-TEST" (CS=Customization Specification) set Description as "Created YYYY/MM/DD by FLast" NEXT import a Sysprep answer file from secure location NEXT Custom settings NEXT click "..." box to right of "Use DHCP" set "Use the following IP settings:" for "IP Address" fill out the first 2 octets set appropriate values for other 2-3 fields set DNS server addresses OK NEXT check "Generate New Security ID (SID)" ALWAYS as template is likely a domain-member computer so it can be updated occasionally NEXT Finish View Inventory VMs and Templates right-click previously completed template Deploy Virtual Machine from this Template provide the new OS name (max15char) select inventory location NEXT select Host/Cluster (wait for validation to succeed) NEXT select Resource Pool (wait for validation to succeed) NEXT select Storage location NEXT check "Power on this virtual machine after creation" select "Customize using an existing customization specification" select desired specification select "Use the Customization Wizard to temporarily adjust the specification before deployment" NEXT NEXT Custom settings? NEXT check "Generate New Security ID (SID)" ALWAYS as template is likely a domain-member computer so it can be updated occasionally NEXT Finish Finish. I know a community member named "brian" (http://serverfault.com/users/25904/brian) has worked with this scenario before, but I couldn't figure out how to contact him directly, so Brian if you see this message could you provide some information to help? Thanks, Brian

• Sendmail Failing to Forward Locally Addressed Mail to Exchange Server

  - by DomainSoil

  I've recently gained employment as a web developer with a small company. What they neglected to tell me upon hire was that I would be administrating the server along with my other daily duties. Now, truth be told, I'm not clueless when it comes to these things, but this is my first rodeo working with a rack server/console.. However, I'm confident that I will be able to work through any solutions you provide. Short Description: When a customer places an order via our (Magento CE 1.8.1.0) website, a copy of said order is supposed to be BCC'd to our sales manager. I say supposed because this was a working feature before the old administrator left. Long Description: Shortly after I started, we had a server crash which required a server restart. After restart, we noticed a few features on our site weren't working, but all those have been cleaned up except this one. I had to create an account on our server for root access. When a customer places an order, our sites software (Magento CE 1.8.1.0) is configured to BCC the customers order email to our sales manager. We use a Microsoft Exchange 2007 Server for our mail, which is hosted on a different machine (in-house) that I don't have access to ATM, but I'm sure I could if needed. As far as I can tell, all other external emails work.. Only INTERNAL email addresses fail to deliver. I know this because I've also tested my own internal address via our website. I set up an account with an internal email, made a test order, and never received the email. I changed my email for the account to an external GMail account, and received emails as expected. Let's dive into the logs and config's. For privacy/security reasons, names have been changed to the following: domain.com = Our Top Level Domain. email.local = Our Exchange Server. example.com = ANY other TLD.

• cron doesn't execute it's commands

  - by Silvio Keller

  I created an own small server with Debian. Last night i updated it. It created an error while generating the initrd and it didn't boot. Today i booted from another filesystem and did dpkg --configure -a with chroot. I also checked the filesystem. Now everything should be ok. But cron doesn't work:-( It is the same /etc/crontab-File but it doesn't work. I reinstalled cron and tried many things. Is there a way to see cron's log? I only readed about rsyslog, but i have not installed rsyslog, because the server is based on a minimal system (Freeagent Dockstar). Has someone an idea? Best regards Silvio Keller Update There is no file /var/log/syslog and dpkg -l|grep syslog gives me no output, so i think syslog is not installed. It is only a minimal system. cron -l gives: cron: can't lock /var/run/crond.pid, otherpid may be 687: Resource temporarily unavailable So i stopped cron with /etc/init.d/cron stop and executed cron -l again, this gives no output. At this moment i tried to start cron with /etc/init.d/cron start: Starting periodic command scheduler: cron failed! But there's no additional error info... But i see there's now in the background a proccess called cron -l which runs. If i stop it /etc/init.d/cron start works: Starting periodic command scheduler: cron. I used the crontab-file /etc/crontab, this worked for me always. Till i updated my kernel and the initrd it doesn't. The file's content is: SHELL=/bin/sh PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin # m h dom mon dow user command 17 * * * * root cd / && run-parts --report /etc/cron.hourly 25 6 * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily ) 47 6 * * 7 root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly ) 52 6 1 * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly ) 00 5 * * * root dummy 23 45 * * 7 root dummy 00 * * * * root dummy */1 * * * * root dummy 00 1 * * * root dummy 00 4 * * * root dummy */5 * * * * root dummy #00 */10 * * * root dummy 01 0 * * * root dummy 00 5 * * * root dummy 00 4 * * * root dummy # If i start crontab -e it creates a new file /tmp/crontab.vn87tv/crontab, which is unfortunaly on a tmpfs and which also doesn't work.

• Why is Excel 2010/2013 taking 10 seconds open any file?

  - by jbkly

  I have a fast Windows 7 PC with two SSDs and 16GB of RAM, so I'm used to programs loading very fast. But recently, for no reason I can figure out, Excel has started taking way too long to open Excel files (of any size--even blank files). This is occurring with Excel 2010 and with Excel 2013 after I upgraded, hoping to solve the problem. Here a couple scenarios: If I start Excel directly, it opens almost instantly. No problem there. If I start Excel directly, and then open any Excel file (.xls or .xlsx), it loads almost instantly. Still no problem BUT if I attempt to open any Excel file directly, with Excel not running, it consistently takes 10-11 seconds for Excel to start. I get no error messages, just a spinning cursor for 10-11 seconds, and then the file opens. During the delay while Excel is trying to start, I'm not really seeing any discernible spike in CPU or memory usage, other than explorer.exe. This problem is only occurring with Excel, not Word or any other program I'm aware of. I've searched around quite a bit on this question and found various others who have experienced it, but the solutions that worked for them are not working for me. For a few people it was a problem with scanning network drives, but my problem is purely with local files; I have no network drives, and the problem persists even with all network connections disabled. Some people suggested worksheets with corrupted formulas or links, but I'm experiencing this with ANY Excel file: even blank worksheets. Others thought it was a problem with add-ins, but I have all Excel add-ins disabled (as far as I can tell). One person solved it by disabling a "clipboard manager" process that was running in the background, but I don't have that. I've disabled as many startup and background processes as I can, but the problem persists. I've run malware scans, disk cleanup, CCleaner, and installed Excel 2013. I've deleted temporary files, enabled SuperFetch, and edited registry keys. Still can't get rid of the problem. Any ideas? My system details: Windows 7 Professional SP1 64-bit, Excel 2013 32-bit, 16GB RAM, all programs installed on SSD.

• Monitoring slow nginx/unicorn requests

  - by injekt

  I'm currently using Nginx to proxy requests to a Unicorn server running a Sinatra application. The application only has a couple of routes defined, those of which make fairly simple (non costly) queries to a PostgreSQL database, and finally return data in JSON format, these services are being monitored by God. I'm currently experiencing extremely slow response times from this application server. I have another two Unicorn servers being proxied via Nginx, and these are responding perfectly fine, so I think I can rule out any wrong doing from Nginx. Here is my God configuration: # God configuration APP_ROOT = File.expand_path '../', File.dirname(__FILE__) God.watch do |w| w.name = "app_name" w.interval = 30.seconds # default w.start = "cd #{APP_ROOT} && unicorn -c #{APP_ROOT}/config/unicorn.rb -D" # -QUIT = graceful shutdown, waits for workers to finish their current request before finishing w.stop = "kill -QUIT `cat #{APP_ROOT}/tmp/unicorn.pid`" w.restart = "kill -USR2 `cat #{APP_ROOT}/tmp/unicorn.pid`" w.start_grace = 10.seconds w.restart_grace = 10.seconds w.pid_file = "#{APP_ROOT}/tmp/unicorn.pid" # User under which to run the process w.uid = 'web' w.gid = 'web' # Cleanup the pid file (this is needed for processes running as a daemon) w.behavior(:clean_pid_file) # Conditions under which to start the process w.start_if do |start| start.condition(:process_running) do |c| c.interval = 5.seconds c.running = false end end # Conditions under which to restart the process w.restart_if do |restart| restart.condition(:memory_usage) do |c| c.above = 150.megabytes c.times = [3, 5] # 3 out of 5 intervals end restart.condition(:cpu_usage) do |c| c.above = 50.percent c.times = 5 end end w.lifecycle do |on| on.condition(:flapping) do |c| c.to_state = [:start, :restart] c.times = 5 c.within = 5.minute c.transition = :unmonitored c.retry_in = 10.minutes c.retry_times = 5 c.retry_within = 2.hours end end end Here is my Unicorn configuration: # Unicorn configuration file APP_ROOT = File.expand_path '../', File.dirname(__FILE__) worker_processes 8 preload_app true pid "#{APP_ROOT}/tmp/unicorn.pid" listen 8001 stderr_path "#{APP_ROOT}/log/unicorn.stderr.log" stdout_path "#{APP_ROOT}/log/unicorn.stdout.log" before_fork do |server, worker| old_pid = "#{APP_ROOT}/tmp/unicorn.pid.oldbin" if File.exists?(old_pid) && server.pid != old_pid begin Process.kill("QUIT", File.read(old_pid).to_i) rescue Errno::ENOENT, Errno::ESRCH # someone else did our job for us end end end I have checked God status logs but it appears CPU and Memory Usage are never out of bounds. I also have something to kill high memory workers, which can be found on the GitHub blog page here. When running a tail -f on the Unicorn logs I see some requests, but they're far and few between, when I was at around 60-100 a second before this trouble seemed to have arrived. This log also shows workers being reaped and started as expected. So my question is, how would I go about debugging this? What are the next steps I should be taking? I'm extremely baffled that the server will sometimes respond quickly, but at others time it's very slow, for long periods of time (which may or may not be peak traffic times). Any advice is much appreciated.

• Error codes 80070490 and 8024200D in Windows Update

  - by Sammy

  How do get past these stupid errors? The way I have set things up is that Windows Update tells me when there are new updates available and then I review them before installing them. Yesterday it told me that there were 11 new updates. So I reviewed them and I saw that about half of them were security updates for Vista x64 and .NET Framework 2.0 SP2, and half of them were just regular updates for Vista x64. I checked them all and hit the Install button. It seemed to work at first, updates were being downloaded and installed, but then at update 11 of 11 total it got stuck and gave me the two error codes you see in the title. Here are some screenshots to give you an idea of what it looks like. This is what it looks like when it presents the updates to me. This is how it looks like when the installation fails. I'm not sure if you're gonna see this very well but these are the updates it's trying to install. Update: This is on Windows Vista Ultimate 64-bit with integrated SP2, installed only two weeks ago on 2012-10-02. Aside from this, the install is working flawlessly. I have not done any major changes to the system like installing new devices or drivers. What I have tried so far: - I tried installing the System Update Readiness Tool (the correct one for Vista x64) from Microsoft. This did not solve the issue. Microsoft resource links: Solutions to 80070490 Windows Update error 80070490 System Update Readiness Tool fixes Windows Update errors in Windows 7, Windows Vista, Windows Server 2008 R2, and Windows Server 2008 Solutions to 8024200D: Windows Update error 8024200d Essentially both solutions tell you to install the System Update Readiness Tool for your system. As I have done so and it didn't solve the problem the next step would be to try to repair Windows. Before I do that, is there anything else I can try? Microsoft automatic troubleshooter If I click the automatic troubleshooter link available on the solution web page above it directs me to download a file called windowsupdate.diagcab. But after download this file is not associated to any Windows program. Is this the so called Microsoft Fix It program? It doesn't have its icon, it's just blank file. Does it need to be associated? And to what Windows program?

• TrueCrypt drive letter not available

  - by Tono Nam

  With c# or a batch file I mount a trueCrypt volume located at A:\volumeTrueCrypt.tc With c# I do: static void Main(string[] args) { var p = Process.Start( fileName:@"C:\Program Files\TrueCrypt\TrueCrypt.exe", arguments:@"/v a:\volumetruecrypt.tc /lw /a /p truecrypt" ); p.WaitForExit(); } the alternative is to run the command on the command line as: C:\Windows\system32>"C:\Program Files\TrueCrypt\TrueCrypt.exe" /v "a:\volumetruecrypt.tc" /lw /a /p truecrypt Either way I get the error: Why do I get that error? I was able to run that command the first time. The moment I dismounted the volume and tryied to mount it again I got that error. I know that drive letter W is available because it shows as an available letter on true crypt if I where to open it manually: If I where then click on the button mount and then type the password truecrypt (truecrypt is the password) then it will successfully mount on drive w. Why I am not able to mount it from the command line!? If I change the drive letter on the command line it works. I want to use the drive W though. In other words executing "C:\Program Files\TrueCrypt\TrueCrypt.exe" /v "a:\volumetruecrypt.tc" /lz /a /p truecrypt will successfully mount that volume on drive z but I do not want to mount it on drive z I want to mount it on drive w. The first time I ran the batch it ran fine. Also if I restart my computer I believe it should work. More info on how to use trueCrypt through the command line can be found at: http://www.truecrypt.org/docs/?s=command-line-usage Edit I was also investivating when does this error occures. In order to generate this error you need to follow this steps. 1) execute the command: (note the /q argument at the end for quiet) "C:\Program Files\TrueCrypt\TrueCrypt.exe" /v "a:\volumetruecrypt.tc" /ln /a /p truecrypt /q "C...TrueCrypt.exe" = location where trueCrypt is located /v "path" = location where volume is located /n = drive letter n /p truecrypt = password is "trueCrypt" /q = execute in quiet mode. do not show window note I am mounting to drive letter n 2) now volume should be mounted. 3) Open trueCrypt and manually dismount that volume (without using command line) 4) Attempt to run the same command line (without the /q so you see the error) "C:\Program Files\TrueCrypt\TrueCrypt.exe" /v "a:\volumetruecrypt.tc" /ln /a /p truecrypt 5) an error should show up So the problem ocures when I manually dismount the volume. If I dismount it from the command line I get no errors. But I think this is a bug from trueCrypt

• Indirect Postfix bounces create new user directories

  - by hheimbuerger

  I'm running Postfix on my personal server in a data centre. I am not a professional mail hoster and not a Postfix expert, it is just used for a few domains served from that server. IIRC, I mostly followed this howto when setting up Postfix. Mails addressed to one of the domains the server manages are delivered locally (/srv/mail) to be fetched with Dovecot. Mails to other domains require usage of SMTPS. The mailbox configuration is stored in MySQL. The problem I have is that I suddenly found new mailboxes being created on the disk. Let's say I have the domain 'example.com'. Then I would have lots of new directories, e.g. /srv/mail/example.com/abenaackart /srv/mail/example.com/abenaacton etc. There are no entries for these addresses in my database, neither as a mailbox nor as an alias. It's clearly spam from auto-generated names. Most of them start with 'a', a few with 'b' and a couple of random ones with other letters. At first I was afraid of an attack, but all security restrictions seem to work. If I try to send mail to these addresses, I get an "Recipient address rejected: User unknown in virtual mailbox table" during the 'RCPT TO' stage. So I looked into the mails stored in these mailboxes. Turns out that all of them are bounces. It seems like all of them were sent from a randomly generated name to an alias that really exists on my system, but pointed to an invalid destination address on another host. So Postfix accepted it, then tried to redirect it to another mail server, which rejected it. This bounced back to my Postfix server, which now took the bounce and stored it locally -- because it seemed to be originating from one of the addresses it manages. Example: My Postfix server handles the example.com domain. [email protected] is configured to redirect to [email protected]. [email protected] has since been deleted from the Hotmail servers. Spammer sends mail with FROM:[email protected] and TO:[email protected]. My Postfix server accepts the mail and tries to hand it off to hotmail.com. hotmail.com sends a bounce back. My Postfix server accepts the bounce and delivers it to /srv/mail/example.com/bob. The last step is what I don't want. I'm not quite sure what it should do instead, but creating hundreds of new mailboxes on my disk is not what I want... Any ideas how to get rid of this behaviour? I'll happily post parts of my configuration, but I'm not really sure where to start debugging the problem at this point.

• Bidirectional real-time sync of large file tree between two distant linux servers

  - by dlo

  By large file tree I mean about 200k files, and growing all the time. A relatively small number of files are being changed in any given hour though. By bidirectional I mean that changes may occur on either server and need to be pushed to the other, so rsync doesn't seem appropriate. By distant I mean that the servers are both in data centers, but geographically remote from each other. Currently there are only 2 servers, but that may expand over time. By real-time, it's ok for there to be a little latency between syncing, but running a cron every 1-2 minutes doesn't seem right, since a very small fraction of files may change in any given hour, let alone minute. EDIT: This is running on VPS's so I might be limited on the kinds of kernel-level stuff I can do. Also, the VPS's are not resource-rich, so I'd shy away from solutions that require lots of ram (like Gluster?). What's the best / most "accepted" approach to get this done? This seems like it would be a common need, but I haven't been able to find a generally accepted approach yet, which was surprising. (I'm seeking the safety of the masses. :) I've come across lsyncd to trigger a sync at the filesystem change level. That seems clever though not super common, and I'm a bit confused by the various lsyncd approaches. There's just using lsyncd with rsync, but it seems this could be fragile for bidirectionality since rsync doesn't have a notion of memory (eg- to know whether a deleted file on A should be deleted on B or whether it's a new file on B that should be copied to A). lipsync appears to be just a lsyncd+rsync implementation, right? Then there's using lsyncd with csync2, like this: http://www.axivo.com/community/threads/lightning-fast-synchronization-with-csync2-and-lsyncd.121/ ... I'm leaning towards this approach, but csync2 is a little quirky, though I did do a successful test of it. I'm mostly concerned that I haven't been able to find a lot of community confirmation of this method. People on here seem to like Unison a lot, but it seems that it is no longer under active development and it's not clear that it has an automatic trigger like lsyncd. I've seen Gluster mentioned, but maybe overkill for what I need? UPDATE: fyi- I ended up going with the original solution I mentioned: lsyncd+csync2. It seems to work quite well, and I like the architectural approach of having the servers be very loosely joined, so that each server can operate indefinitely on its own regardless of the link quality between them.

• Can RPM packages be installed into Cygwin?

  - by Dejian Zhao

  I noticed that there is a command - rpm - under Cygwin 1.7. Does that mean RPM packages can be installed into Cygwin? I tried to install ncbi-blast-2.2.26+-3.i686.rpm (see: ftp://ftp.ncbi.nlm.nih.gov/blast/executables/blast+/LATEST/ ) into Cygwin 1.7.13 with the command "install -i ncbi-blast-2.2.26+-3.i686.rpm". However, error message appeared as below. I tried to search for the missing libs using the setup.exe of Cygwin. It seems that some of them were not present, such as libc.so.6, libdl.so.2, libm.so.6, libnsl.so.1, and libz.so.1. Where can I get these libs?

• APC (PHP Cache) Uptime 0 minutes, not caching

  - by Jussi

  My goal is to implement APC for opcode cache for a drupal 6 production site. I have so far tested APC with several php files with and without including other php files with include_once. Also tried to tweak the apc.ini values for shm_size, apc.include_once_override and apc.stat. Restarted apache every time. Resulting in apc.php not showing any changes in any values. (except of course the changed apc.ini values are shown as they should) Every time i refresh the apc.php test page, the start time resets as the current time showing uptime 0 minutes. apc.php -testpage shows: General Cache InformationAPC Version 3.1.9 PHP Version 5.2.10 APC Host xxxx.xx.xx Server Software Apache/2.2.3 (CentOS) Shared Memory 1 Segment(s) with 128.0 MBytes (mmap memory, pthread mutex Locks locking) Start Time 2011/07/26 11:53:56 Uptime 0 minutes File Upload Support 1 Cached Files 0 ( 0.0 Bytes) Hits 1 Misses 1 Request Rate (hits, misses) 2.00 cache requests/second Hit Rate 1.00 cache requests/second Miss Rate 1.00 cache requests/second Insert Rate 0.00 cache requests/second Cache full count 0 Cached Variables 0 ( 0.0 Bytes) Hits 0 Misses 0 Request Rate (hits, misses) 0.00 cache requests/second Hit Rate 0.00 cache requests/second Miss Rate 0.00 cache requests/second Insert Rate 0.00 cache requests/second Cache full count 0 apc.cache_by_default 1 apc.canonicalize 1 apc.coredump_unmap 0 apc.enable_cli 0 apc.enabled 1 apc.file_md5 0 apc.file_update_protection 2 apc.filters apc.gc_ttl 3600 apc.include_once_override 0 apc.lazy_classes 0 apc.lazy_functions 0 apc.max_file_size 16 apc.mmap_file_mask /tmp/apcphp5.095eRm apc.num_files_hint 1024 apc.preload_path apc.report_autofilter 0 apc.rfc1867 0 apc.rfc1867_freq 0 apc.rfc1867_name APC_UPLOAD_PROGRESS apc.rfc1867_prefix upload_ apc.rfc1867_ttl 3600 apc.serializer default apc.shm_segments 1 apc.shm_size 128M apc.slam_defense 0 apc.stat 0 apc.stat_ctime 0 apc.ttl 7200 apc.use_request_time 1 apc.user_entries_hint 4096 apc.user_ttl 7200 apc.write_lock 1 Host Status Diagrams: Free: 128.0 MBytes (100.0%) Hits: 1 (50.0%) Used: 20.3 KBytes (0.0%) Misses: 1 (50.0%) Detailed Memory Usage and Fragmentation: Fragmentation: 0% phpinfo shows: Server API CGI/FastCGI APC: Version 3.1.9 APC Debugging Enabled MMAP Support Enabled MMAP File Mask /tmp/apcphp5.JkKDk7 Locking type pthread mutex Locks Serialization Support php Revision $Revision: 308812 $ Build Date Jul 21 2011 14:31:12 I followed these steps to find if suexec settings would prevent caching: http://www.litespeedtech.com/support/forum/showthread.php?t=4189 [root@host /]# ps -ef|grep lsphp root 20402 17833 0 11:21 pts/0 00:00:00 grep lsphp [root@host /]# ps -waux root 17833 0.0 0.1 5004 1484 pts/0 S 10:39 0:00 bash ..indicates that there is no lsphp running on the host also I read the following article and comments, concluding that in my case the problem is not the suexec as the user apache is the httpd process owner http://www.brandonturner.net/blog/2009/07/fastcgi_with_php_opcode_cache/ also suexec command is not recognized when logged and launced as root @ host also i'm almost confident that there is no cPanel running on the host to check if a setting there would reset the running cache process at some interval This leaves me with few clues where to head next.

• Automatically Applying Security Updates for AWS Elastic Beanstalk

  - by Eric Anderson

  I've been a fan of Heroku since it's earliest days. But I like the fact that AWS Elastic Beanstalk gives you more control over the characteristics of the instances. One thing I love about Heroku is the fact that I can deploy an app and not worry about managing it. I am assuming Heroku is ensuring all OS security updates are timely applied. I just need to make sure my app is secure. My initial research on Beanstalk shows that although it builds and configures the instances for you, after that it moves to a more manual management process. Security updates won't automatically be applied to the instances. It seems there are two areas of concerns: New AMI releases - As new AMI releases hit it seems we would want to run the latest (presumably most secure). But my research seems to indicate you need to manually launch a new setup to see the latest AMI version and then create a new environment to use that new version. Is there a better automated way of rotating your instances into new AMI releases? In between releases there will be security updates released for packages. Seems we want to upgrade those as well. My research seems to indicate people install commands to occasionally run a yum update. But since new instances are created/destroyed based on usage it seems that the new instances would not always have the updates (i.e. the time between the instance creation and the first yum update). So occasionally you will have instances that aren't patched. And you are also going to have instances constantly patching themselves until the new AMI release is applied. My other concern is that perhaps these security updates haven't gone through Amazon's own review (like the AMI releases do) and it might break my app to automatically update them. I know Dreamhost once had a 12 hour outage because they were applying debian updates completely automatically without any review. I want to make sure the same thing doesn't happen to me. So my question is does Amazon provide a way to offer fully managed PaaS like Heroku? Or is AWS Elastic Beanstalk really more of just a install script and after that you are on your own (other than the monitoring and deployment tools they provide)?

• Setting up a fileserver, some questions?

  - by Tanax

  Recently I've become very interested in setting up a fileserver, mostly for home usage but also because of the fact that I live in 2 places, I need to be able to access my files from both homes. I have already done some research into this but I am unclear about some things. My requirements are the following; Needs to work on both Mac and PC(only using Windows atm on PC but could be good if it supports more OS's to make it futureproof in case I need Linux or something else) Need to be able to set up a folder/drive/network space to act as a link to a certain folder on the fileserver All files should only be stored on the fileserver, e.g. no "shared" folders like in Dropbox where files are stored on the client computer Would prefer it if folders are password protected or that I can somehow specify what users can access the fileserver's shares Fileserver's OS most likely have to be Windows due to other factors outside of being just a fileserver I've already kinda figured out that I will need to set up a VPN so that I can access my fileserver from outside the local network. Probably going to use OpenVPN. Question 1: How would I go about to set up a VPN server so that I can connect to my local network at the fileserver's location? I know that since I'm on a dynamic IP I will have to get some sort of dynamic DNS server - I've already checked into this and I'm fairly sure I know how to fix that. I also know that I will have to forward the port OpenVPN uses in my router. Question 2: How would I actually share the folders on the fileserver so that I can access them on my other computers? I've researched into Samba but I'm uncertain if it needs to be run on a Linux OS. I know that the clients connecting to it can be Windows for example but can the Samba "server" be run on Windows? Also it appears that Samba shares a folder, meaning it works like Dropbox - I don't want that. So how would I share a folder in that case to make it work like I want it to? Sorry for the incredibly long question, I tried to structure it the best I could for easier read. Thanks in advance!
