• path problem with mod_rewrite, XDebug, PDT, XAMPP and Windows XP

  - by Delirium tremens

  My mod_rewrite turns accounts/create into index.php?folder=accounts&action=create, but pdt ignores it, so when I try to start a PHP Script debug session, I have to type a folder location in the file field and pdt doesn't accept. When PDT auto generates the URL for the PHP Web Page debug session, I go to http://localhost/myframe/index.php?XDEBUG%5FSESSION%5FSTART=ECLIPSE%5FDBGP&KEY=12569067976875, but myframe is in the frameworks folder, so I get a 404 error. When I check a breakpoint, uncheck Auto Generate, add frameworks before myframe in URL, set Start Debug from http://localhost/frameworks/myframe/accounts/create in Advanced and click Debug, the debugger doesn't stop at the breakpoint.

• XenServer: Editing clone configuration before boot

  - by Jeff Ferland

  Upon cloning a base image, I need to reconfigure basic settings. Regenerating the ssh host key, changing static IP assignments, setting the host name, etc. Because of the network setup, DHCP is not an option. That more or less rules out SSHing in with a predefined key or running a startup script since I can't provide the IP externally. I'd most like to mount the filesystem of the new machine on Dom0, but the lvm volumes are exported and it appears to be Bad Form to import them so the Dom0 machine can see them. What's your best suggestion for altering files in a cloned VM before boot? Must be non-interactive, and I'm going to guess out the gate that scripting access via xe console is not going to work well.

• Using Find, Grep, Awk, or Sed To Rename Server After Cloning

  - by ServerChecker

  My client tells me they have cloned a VM in VMWare of an Ubuntu Linux server. Now it's my job to get into all the files and find out what still has the old server name of "bishop" and change it to something else. Also, the IP address is changed and I need to search for that too. How would you typically use find, grep, awk, or sed to find these files and then change them rapidly? In the end, I want to make a Bash script. Of course, I'm not expecting you to tell me every file, but just want to know the technique for finding files with "x" in it and then switching that rapidly with "y".

• PHP cgi locks up and times out.

  - by Oli

  I've got a dozen wordpress sites hosted on a nginx/php-cgi setup. After a variable amount of time (usually not that long, and occasionally very fast) PHP locks up and after 2 minutes (the timeout I set in nginx), it get a 504 timeout. I've tried everything I can think of. I've been using an init script to launch php-cgi but I compiled out php-fpm and tried that for a day with various configurations with the same results. I've tried a low number of PHP_FCGI_CHILDREN. I've tried as high as my RAM will let me. I've tried various settings for PHP_FCGI_MAX_REQUESTS. xcache seemed to exacerbate the issue, so I removed it. The server is a VPS but it has over a gig of ram dedicated to it. All suggestions are welcome at this juncture because I'm desperate.

• Query performance counters from powershell

  - by Frane Borozan

  I am trying this script to query performance counters in different localized windows server versions. http://www.powershellmagazine.com/2013/07/19/querying-performance-counters-from-powershell/ Everything works as in the article, well partially :-) I am trying to access a counter ID 3906 Terminal Services Session and works well for English windows. However for example in French and German that counter doesn't exist under that ID. I think I figured to find the exact counter under ID 1548 in french and German, but that ID in English is something completely different. Anybody seen this behavior on the performance counters?

• Mysql not loading correctly

  - by mcondiff

  PHP 5.3.2 Apache 2.2.15 Mysql 5.1.X Windows XP SP3 I have now configured everything correctly but get a timeout when trying to connect to Mysql via PHP. So frustrated. I don't get an error message, the script just times out. I have made sure I have the correct paths. Fatal error: Maximum execution time of 60 seconds exceeded Any idea why this might be happening? I do a php -v from the command line and everything is normal, no errors. i upgraded PHP from 5.2.6 to 5.3.2 - does there seem to be problems or bugs with this? I am essentially using my previous PHP.ini while editing paths. I am lost. Help! If you need anything from phpinfo() or httpd.conf or php.ini let me know. else

• Use pt-table-sync to setup a new MySQL DB

  - by Generation D Systems

  I have 2 hosts (A and B). B contains a MySQL server with a database called mydb, and A contains a MySQL server with nothing (fresh install). I want to replicate the entire mydb from B to A, by running a script on A (I do not have shell access to B). Can I run this on A: pt-table-sync --execute h=b.mydomain.com,D=mydb h=a.mydomain.com I've read the docs but don't get a 100% comfort feeling (perhaps because of all the warnings about damaging your data if you don't know what you're doing). Will this work? as well, is h=a.mydomin.com necessary? (Will it route all traffic back in/out the local NIC?) can I use localhost or nothing at all?

• Best approach to utilize RamDisk for Chrome?

  - by laggingreflex

  I use a lot of tabs and after a while less recently opened tabs take some time to become responsive, which I guess is because they're being un-cached to HDD as they're not required. So after creating a Ram-Disk I have two options, use --disk-cache-dir="G:/" switch to do what it does. Or what I'm currently doing: using a directory junction for "[...]\AppData\Local\Google\Chrome\User Data\Default" to move that entire folder over to Ram-Disk. I thought this would be better than just disk-cache but what do I know. Is it? As one can guess it'll be a pain saving/loading the Ram-Disk image each time I start chrome but if it really is better than the former approach I'll write a script or something.

• SSH via DHCP server

  - by SFault

  I have a DHCP server setup and I can't seem to connect to anything through SSH. When I'm logged in to the server itself, I can SSH. But when I connect any machine to the DHCP server, that machine can SSH but every server I SSH to asks for a password when the normal behavior (when not connected to the DHCP server) does not. Here are the contents of my iptables script that are related to port 22. $IPT -t nat -A PREROUTING -i $LAN -p tcp --dport 22 -j REDIRECT --to-port 22 $IPT -A FORWARD -i $LAN -p tcp --dport 22 -j ACCEPT $IPT -A INPUT -i $LAN -p tcp --dport 22 -j ACCEPT $IPT -A INPUT -i $WAN -p tcp --dport 22 -j ACCEPT $IPT -A OUTPUT -p tcp --sport 22 -m state --state ESTABLISHED -j ACCEPT $IPT -A INPUT -i $LAN -p tcp --dport 22 -m state --state NEW,ESTABLISHED -j ACCEPT Am I missing something?

• How can I poll different aws sqs in the same process?

  - by Luccas

  What is the right way to poll from differents AWS SQS in the same process? Suppose I have a ruby script: listen_queues.rb and run it. Should I need to create threads to wrap each SQS poll or start sub processes? t1 = Thread.new do queue1.poll do |msg| .... end t2 = Thread.new do queue2.poll do |msg| .... end t2.join I tried this code, but the poll is not receiving any of the messages available. When I run only one of them (t1 or t2), it works. But I need the 2 running. What is going on? Thanks!!

• Can I use nginx to start EC2 instances on demand?

  - by Gabe Hollombe

  TL;DR - Is there a way to make nginx act as an elastic load balancer that will spin up EC2 instances on demand, allowing for the case when periods of no demand mean no instances will be running? Longer explanation - I have an nginx server that proxy_pass'es requests to a server on EC2. This server doesn't get many requests, so I'd like to keep the server spun down during periods of inactivity (I already have a script to do this). Then, when the instance is spun down and nginx gets a request for that instance, it will time out when trying to get a response from it. At this point, can I somehow trigger a shell command on the server to use EC2's command line tools to spin up the instance, then re-try the user's request after it has started?

• Trying to mount NFS share on Windows Machien at startup with Z: letter for all users

  - by ScottC

  Windows Server 2008 We are trying to mount a specific drive letter on a windows machine from a unix machine. We need the mount to be available to the server even if no users are logged in and to users who are logged in with If we run the command from the command prompt manually it conencts and we have access to the NFS share, and can open it and see and edit files. mount -o fileaccess=777 anon \\127.0.0.1\nav z: (ip address replaced with 127.0.0.1 for security reasons) However if we try to automate the task by making an entry in the task schedule for boot time, to execute the batch script, it adds a disconencted drive to the list in 'My Computer' but it is disconencted and when trying to access the drive an error is produced: Z: is not accessible The data area passed to a system call is too small.| Tried as administrator with highest privelidges, as SYSTEM (group) and as my user (adminstator level user) same results. Is there another way to do this? Most of the help I have found online suggest this way but it keeps failing.

• SQL SERVER – T-SQL Scripts to Find Maximum between Two Numbers

  - by pinaldave

  There are plenty of the things life one can make it simple. I really believe in the same. I was yesterday traveling for community related activity. On airport while returning I met a SQL Enthusiast. He asked me if there is any simple way to find maximum between two numbers in the SQL Server. I asked him back that what he really mean by Simple Way and requested him to demonstrate his code for finding maximum between two numbers. Here is his code: DECLARE @Value1 DECIMAL(5,2) = 9.22 DECLARE @Value2 DECIMAL(5,2) = 8.34 SELECT (0.5 * ((@Value1 + @Value2) + ABS(@Value1 - @Value2))) AS MaxColumn GO I thought his logic was accurate but the same script can be written another way. I quickly wrote following code for him and which worked just fine for him. Here is my code: DECLARE @Value1 DECIMAL(5,2) = 9.22 DECLARE @Value2 DECIMAL(5,2) = 8.34 SELECT CASE WHEN @Value1 > @Value2 THEN @Value1 ELSE @Value2 END AS MaxColumn GO He agreed that my code is much simpler but as per him there is some problem with my code which apparently he does not remember at this time. There are cases when his code will give accurate values and my code will not. I think his comment has value but both of us for the moment could not come up with any valid reason. Do you think any scenario where his code will work and my suggested code will not work?

• MS Server 2003 Activiation Loop

  - by RPGonzo

  Recently we had a motherboard failure on a terminal server so we replaced the faulty motherboard, re-setup the RAID arrays (same motherboard but still wouldn't recognize old RAID setup) and continued to recover the system from a previous backup. No problem up to here, after restoring the system you are prompted to reboot and than login. On login we get a message box stating that Windows needs to be activated do you want to activate now, press yes but than the OS proceeds to log you off and do nothing at all. You can try over and over but to no avail. Found a few articles about a glitch in the activation script and how to reset it, tried that with the same results. Hoping someone can share some knowledge if you have seen this before? Thanks!

• Printer ports missing from network printers, Windows 7 laptops

  - by pigeon

  Have an odd issue where users take their laptops home and back into the office with network printers that get mapped via a login script but fail to print. After tracking down a user with this problem I found that the print driver had no ports available to it. We've mapped network printers for this site all the time but only since the introduction of the Konica Minolta C220 Bizhub has this issue cropped up. The issue occurs with Windows 7 users and it takes them 2 /3 reboots to have the ports recreated. Should I be looking at the server for this or at the Windows 7 machines?

• using ksar from command line

  - by Monir

  I am working on creating system monitoring graphs from sar outputs. Ksar seems to be a nice gui tool, with some command line support. My goal is to create pdf/png charts from a script using ksar command line. The released version has some minor bugs where I got some exceptions. Fortunately the beta 5.1.0_beta4 does not have the bugs and produces nice graphs from GUI. But I cannot seem to run the command line version. Trying to create a pdg/chart from command line is always bringing the GUI. Anyone had experience using command line ksar to produce pdfs/pngs?

  I've been trying to install Kannel opensource gateway for sending free sms on my computer. But I never managed to make it work by reading the guide from the official website. So I'm starting over and interested in all information I can get. What hardware do I need? Can I install it on Ubuntu 12.04? Could someone post a link of a good tutorial, or write one here on step-by-step Kannel installation. Edit: Also, an example of sms sending using a php script would be appreciated.

• Diagnosing xmodmap errors

  - by intuited

  I'm getting this error when trying to use xmodmap to get rid of caps lock: $ xmodmap -e 'clear Lock' X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 118 (X_SetModifierMapping) Value in failed request: 0x17 Serial number of failed request: 8 Current serial number in output stream: 8 I'm running xfce on Maverick "10.10" Meercat. This problem did not occur before I added the Keyboard Layouts applet to a panel; before doing that, I was able to run my xmodmap script to swap Esc and CapsLock: !Remap Caps_Lock as Escape remove Lock = Caps_Lock keysym Caps_Lock = Escape It may be relevant that I chose alt-capslock as the keyboard switch combo in the Keyboard Layouts preferences. I've had a similar problem before, on a different machine, running openbox. On that machine, this problem started when I upgraded to Lucid, and has persisted in Maverick (release 10.10). I reported a bug in xorg. However, it remains unclear whether it's really a problem with xorg, or if I'm just doing something wrong with my configuration. Have other people experienced this problem? Can someone shed some light on what's going on here? It seems there are quite a few layers involved, and I don't understand any of them particularly well, so any information would be helpful. update I've discovered that the problem is specifically triggered by adding the Canada layout variant "Multilingual" (ca-multix). If I instead add the variant "Multilingual (first part)", the problem does not occur. I think this will probably end up being a usable workaround, but I don't yet know what the difference between these variants is. I've filed a freedesktop issue, and am commenting on a related ubuntu issue.

• apache virtual host concept and dns

  - by Subhransu

  I want to have around 60 repositories of projects and I want to serve them from a dedicated remote server(ubuntu) with the help of mercurial server so that all my developers will be able to update their changes. I have followed this article in order to do that but stocked in the Apache Configuration Step (section 2.5 2.5.4). I have some following questions: What are the steps I need to follow to make apache to serve /home/hg/repositories/private/hgweb.cgi when I enter dev.example.com/private ? Is my virtual host file is correct or do I need to change anything ? I bought the example.com and how to make it to serve dev.example.com/private.

• Hardening network with sysctl settings made Wi-fi downloading speed extremely slow

  - by Rohit Bansal

  I just followed up following steps to harden network security The /etc/sysctl.conf file contain all the sysctl settings. Prevent source routing of incoming packets and log malformed IP's enter the following in a terminal window: sudo vi /etc/sysctl.conf Edit the `/etc/sysctl.conf` file and un-comment or add the following lines : # IP Spoofing protection net.ipv4.conf.all.rp_filter = 1 net.ipv4.conf.default.rp_filter = 1 # Ignore ICMP broadcast requests net.ipv4.icmp_echo_ignore_broadcasts = 1 # Disable source packet routing net.ipv4.conf.all.accept_source_route = 0 net.ipv6.conf.all.accept_source_route = 0 net.ipv4.conf.default.accept_source_route = 0 net.ipv6.conf.default.accept_source_route = 0 # Ignore send redirects net.ipv4.conf.all.send_redirects = 0 net.ipv4.conf.default.send_redirects = 0 # Block SYN attacks net.ipv4.tcp_syncookies = 1 net.ipv4.tcp_max_syn_backlog = 2048 net.ipv4.tcp_synack_retries = 2 net.ipv4.tcp_syn_retries = 5 # Log Martians net.ipv4.conf.all.log_martians = 1 net.ipv4.icmp_ignore_bogus_error_responses = 1 # Ignore ICMP redirects net.ipv4.conf.all.accept_redirects = 0 net.ipv6.conf.all.accept_redirects = 0 net.ipv4.conf.default.accept_redirects = 0 net.ipv6.conf.default.accept_redirects = 0 # Ignore Directed pings net.ipv4.icmp_echo_ignore_all = 1 To reload sysctl with the latest changes, enter: sudo sysctl -p But, after applying the changes I found "Wi-fi" downloading speed and terminal downloading speed extremely slow (less than 1KB/s) however surfing speed through browser was good. But, using direct ethernet cable was giving a good speed. Then, I reverted back the above changes and things fall back in line once again.... Could you please let me know what possibly in above script is affecting such behaviour [and why] ? How could I still maintain hardening of network security without disturbing Wi-fi downloading speed ?

• Why do Finder and du report different file size?

  - by flipdoubt

  I am writing a geektool 3 script to show the size of a particular VMware Fusion virtual machine. Get Info in Finder says the file is "52.91 GB". I run the following du command to get the file size: > du -hs ~/Documents/Virtual\ Machines.localized/MY-PRECIOUS-7.vmwarevm | awk '{print $1}' This du -hs command returns the file size as "49G". What accounts for the difference from what Finder reports? Alternatively, I have tried replacing the -s option with the -d option like so: du -hd ~/Documents/Virtual\ Machines.localized/MY-PRECIOUS-7.vmwarevm | awk '{print $1}' This du -hd command returns the file size as "59G". What accounts for the difference between Finder, du -hd, and du -hs? Also, this du -hd command produces no output in geektool 3. What gives?

• Php.ini: Local Value vs Master Value (safe_mode, specifically)

  - by Philipp Lenssen

  I can change php.ini values on my Apache and restart to see them in effect via a script showing php_info(). However, one setting is causing problems: safe_mode. I set it to "off" in php.ini but php_info() still shows it as Local value: On Master value: Off How can I find out which local value is overriding the master value? There's no htaccess directive of that kind in the httpdocs folder in question...
