• Firefox 29 - how do I delete history entries visited fewer than x times

  - by lousyuser

  Context: I've been using my Firefox profile for a couple of years now. My history file has become huge, naturally. I got Firefox Sync set up between my main desktop PC and my laptop. HW configs: PC: i5-3450, 8 GB DDR3 RAM, Crucial M4 128 GB SSD laptop: Pentium SU4100, 4 GB DDR3 RAM, WD 5400 rpm HDD Accessing history entries when typing into the Awesome Bar on my desktop takes quite a long time despite the decent config, the laptop is even slower. The experience is quite unresponsive. I figured if I cleared the history up a little bit, I might avoid creating a new profile to speed things up. The question itself: to illustrate: Is there a way to delete all history entries that have been visited fewer than x (let's say 5) times and at the same time the recent visit is fewer than y (let's say 120) days old? afaik the history file is some kind of SQL database, but I'm not really sure how the data is saved, if there's a "safe way" to edit it and what the query to do what I need would look like. Thanks in advance for any help. I kept browsing through previous SuperUser questions to see if I could find relevant information. "In my Firefox profile directory, there is a filed named places.sqlite. Opening it with sqlite reveals (amongst others) the tables moz_places and moz_historyvisits. It seems that moz_historyvisits uses the primary of moz_places to refer to the URLs." As I'm unfamiliar with databases, I don't really understand the way the two tables mentioned in the quote are related. screenshot of a part of the tables I've noticed the visit_count is in a standard format, making it easy to work with. The last_visit_date looks encrypted to my naked eye, but I can't see in which way. Hope that helps, I'm at my wits' end.

• copy large LVM volume(14TB) from one server to another

  - by bruce

  recently,I have to copy a very large LVM volume()rom server A to server B. Below is the filesystem of server A and server B - server A [root@AVDVD-Filer ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_avdvdfiler-lv_root 16T 14T 1.5T 91% / tmpfs 3.0G 0 3.0G 0% /dev/shm /dev/cciss/c0d0p1 194M 23M 162M 13% /boot /dev/mapper/vg_avdvdfiler-test 2.3T 201M 2.1T 1% /test /dev/sr0 3.3G 3.3G 0 100% /mnt server B [root@localhost ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup-LogVol00 20G 2.5G 16G 14% / tmpfs 3.0G 0 3.0G 0% /dev/shm /dev/cciss/c0d0p1 194M 23M 162M 13% /boot /dev/mapper/VolGroup00-LogVol00 16T 133M 15T 1% /xiangao/lv1 /dev/mapper/VolGroup00-LogVol01 4.7T 190M 4.5T 1% /xiangao/lv2 I want to copy LVM volume /dev/mapper/vg_avdvdfiler-lv_root on server A to LVM volume /dev/mapper/VolGroup00-LogVol00 on server B . The server A and server B is in the same IP segment. IN the LVM volume on server A , there is all average 500M avi wmv mp4 etc. I tried mount /dev/mapper/vg_avdvdfiler-lv_root on server A to server B through NFS , then use cp command copy. It is clear I faild . Because the LVM volume is too big , I do not have good idea . I hope a good solution here. I'm a chinese, my english is very pool. sorry thanks everyone!

• How to give wife emergency access to logins, passwords, etc.?

  - by Torben Gundtofte-Bruun

  I'm the digital guru in my household. My wife is good with email and forum websites but she trusts me with all our important digital stuff -- such as online banking and other things that require passwords, but also family photos and the plethora of other digital things in a modern home. We discuss relevant actions but it's always me that executes the actions. If I should get "hit by a bus" then my wife would be thoroughly stranded -- she would have no idea what digital stuff is where on our computer, how to access it, what online accounts we have, and their login credentials are. It would also leave my many public appearances (personal websites, email accounts, social networks, etc.) unresolved. To complicate things, I'm one of those people who don't use password as my password everywhere; I use a mix of SuperGenPass and LastPass, and also two-factor authentication whenever possible. I don't have much hope that she would find her way through a written explanation of all that in a stressful situation. I could just tell her that she should ask my tech-savvy twin brother and then entrust him with my LastPass master passphrase. I feel that would have a high chance of success, but it's inelegant and leaves my wife without control of the information. How can I ensure that my wife has access to my digital remains?

• Apache2 Manage Server default

  - by Jaime E. Valdez

  I'm trying to setup two domains correctly. I have some issues I hope you can help me. Site one's conf: <VirtualHost myipaddress:80> ServerName www.domain1.com ServerAdmin [email protected] DocumentRoot /home/domain1/public_html </VirtualHost> My other domain conf is: <VirtualHost myipaddress:80> ServerName www.domain2.com ServerAlias *.domain2.com domain2.com ServerAdmin [email protected] DocumentRoot /home/domain2/public_html </VirtualHost> The default site is disabled. The problem is that when accessing "domain2.com" from my browser, it always redirects to "www.domain1.com". It only works when I excplicitly access "www.domain2.com". I have also other domains like "domain1.net", "domain1.info" pointing to my server but at this moment are not configured either setup on Apache yet I can access from browser and always accessing to "www.domain1.com". By the way is there any possible configuration over Apache to handle IP only, I mean if I type "http://myipaddress/" I get the "www.domain1.com"... Arrgh.

• PPP kernel module fails to load

  - by Harel

  I am trying to deal with a problem on a server I don't normally deal with. Out of the blue a script using ppp started failing saying that the ppp kernel module is not loaded. When I try to modprobe it it complains about files missing. Note below that the kernel version the server thinks it at, does not match the kernel version directory in /lib/modules. I'm not sure how this could have happened. Could the other maintainers of the server botched a kernel upgrade? My question is how can I fix this discrepancy. Can I simply rename the lib directory and hope for the best? I don't want to break stuff for the people who actually maintain the server but I do need to fix the PPP issue. $ sudo /sbin/modprobe -v ppp FATAL: Could not load /lib/modules/2.6.35.4-rscloud/modules.dep: No such file or directory $ cat /proc/version Linux version 2.6.35.4-rscloud ([email protected]) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #8 SMP Mon Sep 20 15:54:33 UTC 2010 $ ls /lib/modules/ 2.6.33.5-rscloud

• Concerns about Apache per-Vhost logging setup

  - by etienne

  I'm both senior developer and sysadmin in my company, so i'm trying to deal with the needs of both activities. I've set up our apache box, wich deals with 30-50 domains atm (and hopefully will grow larger) and hosts both production and development sites, with this directory structure: domains/ domains/domain.ext/ #FTPS chroot for user domain.ext domains/domain.ext/public #the DocumentRoot of http://domain.ext domains/domain.ext/logs domains/domain.ext/subdomains/sub.domain.ext domains/domain.ext/subdomains/sub.domain.ext/public #DocumentRoot of http://sub.domain.ext Each domain.ext Vhost runs with his dedicated user and group via mpm-itk, umask being 027, and the logs are stored via a piped sudo command, like this: ErrorLog "| /usr/bin/sudo -u nobody -g domain.ext tee -a domains/domain.ext/logs/sub.domain.ext_error.log" CustomLog "| /usr/bin/sudo -u nobody -g domain.ext tee -a domains/domain.ext/logs/sub.domain.ext_access.log" combined Now, i've read a lot about not letting the logs out of a very restricted directory, but the developers often need to give a quick look to a particular subdomain error log, and i don't really want to give them admin rights to look into /var/logs. Having them available into the ftp account is REALLY handy during development stages. Do you think this setup is viable and safe enough? To me it is apparently looking good, but i'm concerned about 3 security issues: -is the sudo pipe enough to deal with symlink exploits? Any catches i'm missing? -log dos: logs are in the same partition of all domains. got hundreds of gigs, but still, if one get disk-space dos'd, everything will break. Any workaround? Will a short timed logrotate suffice? -file descriptors limits: AFAIK the default limit for Apache on Ubuntu Server is currently 8192, which should be plenty enough to handle 2 log files per subdomain. Is it? Am i missing something? I hope to read some thoughts on the matter!

• changing filesystem format from xfs to ext4 without losing data

  - by A.Rashad

  I have a fresh Lucid Lynx (Ubuntu 10.04) running on a laptop. where I defined the filesystems as: mount point / on ext4 (46 Gb) mount point /home on jfs (63 GB) swap as 3 Gb I left the machine over night to do some task, without AC power supply. next day in the morning I found it on standby, task completed, but filesystem was not reachable. it gave me I/O error it seems that there is a problem with jfs and standby. anyways, to avoid any hassle, I want to move this mount point from jfs format to ext4. can I do this without losing data and without the need to place the data in a temporary location until transformation is done? sorry to mention that, but I recall back in the windows days, we would change a FAT16 to FAT32 or a FAT32 to NTFS without having to lose the data. I hope this is available on Linux. Update The /home filesystem was xfs not jfs, and it seems there is a bug with this filesystem for some reason, I had to re-install the OS twice until I ended up with ext4 for the entire / However, as a conclusion, it seems that there is no way to make a conversion

• Error in Apache: /var/run/apache2 not found

  - by Julen

  This is more self-answered question but since it drove me crazy I would like to share with the community and maybe someone can tell me why it happened or what it caused. The thing is I wanted to install in my Ubuntu 10.4 machine a CGI app, one built in the samples that come with the gSOAP toolkit. My intention was to access those from ASP .NET machine. Regular Ubuntu does not come with Apache so I install it from Sypnatic. Pretty easy. I followed this How to Install Apache2 webserver with PHP,CGI and Perl Support in Ubuntu Server. Instead of apache.conf I tweaked httpd.conf since a college here used that file instead of the first to put his Apache running. Besides I was able to access his CGI from my ASP .NET but mysteriously I could not from mine, I was getting always "The request failed with HTTP status 503: Service Temporarily Unavailable". Checking Apache error.log I found these messages: No such file or directory: unable to connect to cgi daemon after multiple tries: /home/julen/htdocs/cgi-bin/calcserver And looking more carefully whenever I restarted Apache I got this other message No such file or directory: Couldn't bind unix domain socket /var/run/apache2/cgisock. cgid daemon failed to initialize I am pretty new with Ubuntu and I could not think that Apache and Synaptic made a mistake in the installation process of the server, but it is true that the /var/run/apache2 was missing whereas in my college's computer was not. I tried to find and "elegant" solution but I found a post from 2006 that had an slight reference to it. Finally I decided to create the folder myself (as root) and then everything worked fine. Hope this helps others if they encounter a similar problem. Still I have the doubt why the folders was not created in the first place. Best, Julen.

• ajax.googleapis.com stopping my Firefox

  - by Oscar Reyes

  Today for some strange reason, Firefox stops working properly because it is trying to fetch something from ajax.googleapis.com. Is there something I can do to avoid this? Safari and Chrome work just fine. I tried uninstalling Firebug and clearing the cache. The only thing that worked was disabling the JavaScript altogether. This seems to be the culprit link: http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js What can I do? EDIT I think I have found where the problem is. My proxy is serving one byte at a time the file, so firefox consume it at that peace. What I don't understand is why Safari and Chrome takes it right away. What I did last night was, leave the FF open all the night to give him change to load the file, my hope was that I got cached and the next time there was no need to go for it. Today in the morning, the page load successfully but the page was not cached, because the next request failed the same. Here's a video showing the problem:

• How to make new file permission inherit from the parent directory?

  - by Wai Yip Tung

  I have a directory called data. Then I am running a script under the user id 'robot'. robot writes to the data directory and update files inside. The idea is data is open for both me and robot to update. So I setup the permission and owner group like this drwxrwxr-x 2 me robot-grp 4096 Jun 11 20:50 data where both me and robot belongs to the 'robot-grp'. I change the permission and the owner group recursively like the parent directory. I regularly upload new files into the data directory using rsync. Unfortunately, new files uploaded does not inherit the parent directory's permission as I hope. Instead it looks like this -rw-r--r-- 1 me users 6 Jun 11 20:50 new-file.txt When robot tries to update new-file.txt, it fails due to lack of file permission. I'm not sure if setting umask helps. In anycase the new files does not really follow it. $ umask -S u=rwx,g=rx,o=rx I'm often confounded by Unix file permission. Do I even have a right plan? I'm using Debian lenny.

• Using UDF on a USB flash drive

  - by CesarB

  After failing to copy a file bigger than 4G to my 8G USB flash drive, I formatted it as ext3. While this is working fine for me so far, it will cause problems if I want to use it to copy files to someone which does not use Linux. I am thinking of formatting it as UDF instead, which I hope would allow it to be read (and possibly even written) on the three most popular operating systems (Windows, MacOS, and Linux), without having to install any extra drivers. However, from what I found on the web already, there seem to be several small gotchas related to which parameters are used to create the filesystem, which can reduce the compability (but most of the pages I found are about optical media, not USB flash drives). I would like to know: Which utility should I use to create the filesystem? (So far I have found mkudffs and genisoimage, and mkudffs seems the best option.) Which parameters should I use with the chosen utility for maximum compability? How compatible with the most common versions of these three operating systems UDF actually is? Is using UDF actually the best idea? Is there another filesystem which would have better compatibility, with no problematic restrictions like the FAT32 4G file size limit, and without having to install special drivers in every single computer which touches it?

• Apache2 - Hosting two sites on the same domain with different ports

  - by user1026361

  I am hosting a staging site (test.mydomain.com) which currently work well on port 80 for two sites (test.mydomain.com and test.FRmydomain.com) I am working on a new backend and I would like to deploy a third site on this server for testing. My hope is that it will live at test.mydomain.com:4204. I've got some experience with apache and quickly added statements: Listen 4204 NameVirtualHost *:4204 and created a new config for my site. What I imagine are the relevant parts of my config: <VirtualHost *:4204 > ServerAdmin [email protected] ServerName test.mydomain.com:4204 However, the site is not publicly available, by name or ip. If i curl localhost:4204 from the server, I get the expected page content At this point, I'm a bit of a loss on how to go forwards. It seems like my config is correct but not available to be served. Am I better off defining a proxy definition so that, for instance: test.mydomain.com/4204 proxies to my localhost server or is there a way to make the site available via the internet? EDIT: I have added an iptable rule after further Googling with the command: iptables -I INPUT -p tcp --dport 4204 -j ACCEPT I can see apache listening on 4204 and the rule is definitely in place but cant reach the site

• passing on command line options in bash

  - by bryan

  I have a question. I have a script, a kind of long script written in bash aprox. 370 lines. That has several functions and in those functions the user has to enter information which is then stored in files. ( This is suppose to represent a MySQL database, with the functions INSERT, UPDATE, SELECT, SELECT where x=y.) I created this myself in bash, now the only thing that rests me is that I need to be able to pass arguments on the command line to the script, that will do the same as the script does. I know that bash has positional parameters such as $1 $2 $3 $* $@ $0 ( refers to the name of the script) etc. I know how I can use these parameters in a simple if function. This is not enough for my script. I basicly need to do the same thing that the script does, but then from the command line. I have been struggling with this for a couple of days now and I cannot think of a way to get it to work. Maybe someone here can help me with this? If you want to have the script. That can be possible, but I don't think I can paste it in here... EDIT: Link to script, http://pastebin.com/Hd5VsDv2 Note, I am a beginner in bash scripting. EDIT: This is in reply to Answer 1. As I said I hope I can just replace the if [ "$1" = "one" ] ; then echo "found one" to if [ "$1" = "one" ] ; then echo SELECT where SELECT is the function I previously had in my script(above) http://pastebin.com/VFMkBL6g LINK to testing script

• MySQL Master-Master w/ multiple read slave cost effective setup in AWS

  - by Ross

  I've been evaluating Amazon Web Services RDS for MySQL and costing out potential scenarios involving a simple multi-AZ deployment read/write setup vs. a multi-AZ deployment mysql master (hot-standby) with additional read-only slaves. the issue I'm trying to cost-optimize includes their reserved instance vs on-demand instances. Situation 1: purchase reserved multi-az setup for Extra-large-hi-mem(17GB RAM) instance for $5200/yr and have my application query the master all the time. the problem is, if I don't need all the resources of the (17GB RAM) all the time and therefore, especially not a hot-standby, what alternatives for savings can a better topology create, like potentially situation 2 below: Situation 2: purchase reserved multi-az setup using smaller master instances than above for the master-master hot-standby to receive the writes only. Then create and load balance several read-only slaves off the master and add/remove and/or scale up/down the read slaves based on demand. This might only cost $1000 + the on-demand usage of the read slaves. My thinking is, if I have a variable read-intensive application load, with low write load, the single level topology in situation 1 means I'm paying for a lot of resources at the write level of topology when I don't need them there. My hope is that situation 2 can yield cost savings from smaller reserved instances on the master-master resource level allowing me to scale up and down and/or out on the read-level according to demand as needed. Does anyone see a downside to doing this or know of some reason this isn't possible with RDS? Any other thoughts or advice always welcome of course. Thanks in advance, R

• SQL Server 2008 second instance times out when logging in -- but only the first time?

  - by Kromey

  This is a strange one that has plagued me for a while now. When logging in to the second instance of SQL Server 2008 on one of our database servers, we get a timeout error: Cannot connect to servername\mssqlserver2. Additional information: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. (Microsoft SQL Server)") (This is the error message when trying to connect with Microsoft SQL Server Management Studio; other tools experience the same error, but of course say it in different ways.) Immediately re-attempting to log in works just fine, so whatever the cause it's ephemeral! This happens regardless of user or authentication type (both Windows and SQL Server authentication methods are supported on this instance). What's even weirder, though, is that the first instance on this server has never once demonstrated this problem. Server is a Windows Server 2008 R2 virtual server, hosted in Microsoft Hyper-V (host is likewise Server 2008 R2). The server has 2GB of RAM, and seems to regularly be using 90% of that -- could low memory be the cause of this issue? I could see this second instance -- which is not used very often yet -- being swapped out to disk, and then taking too long to load back into memory to respond in time to the connection request, but I'd rather have more than just my own hunch before I go scheduling a downtime for this server (the first instance is used regularly) and then just throwing extra resources at it in the blind hope that the problem goes away.

• Mac OS X - configuring ntpd server with on LAN with D-Link DIR-655

  - by Mark C

  Hey all, This question is pretty specific, but I hope someone will have seen this error elsewhere. I a configuring a machine running OS X 10.5.8 to be an NTP server for machines connected to a LAN that is not connected to the Internet. I am not too worried about knowing the "right" time on all the machines, but rather worried about making sure everyone has the same notion of time. I configured the NTP daemon on Mac by turning on the Set date and time automatically in System Preferences, using the server's clock, 127.127.1.0 as the reference clock. I figured I should see if the server can NTP query itself before proceeding to the clients. The weird part is when I run the ntpq -p command in a command-prompt when connected to my D-Link DIR-655 (firmware: 1.33), it hangs for about a minute or so each time before finally giving me some output. I thought the problem might have to do with Port Forwarding, so I configured the router to forward port 123 for the IP of the server, but that did not improve the situation. When I run the ntpq -p command on my school's network, on a Linksys WRT54G router, or with the wireless Airport card turned off - I have absolutely no problems - the command returns a response instantly. Is this normal? I can see why a query might take a minute or so, but I don't understand why one router does it faster than the other. I tried messing around with the ntp.conf file adding the burst, minpoll, and maxpoll options: server 127.127.1.0 burst minpoll 4 maxpoll 5 Figuring that perhaps I am polling too often and the configuration file is slowing me down, but even with this, the ntpq still hangs on the D-Link DIR-655, but does just fine on the other routers. Any thoughts on where the lag is coming from or if the lag is even a problem?

• Sharepoint (WSS 3.0) on SBS 2008 broken.

  - by tcv

  I recently ran the Sharepoint Products and Technologies Wizard. I had hoped this would bring up Sharepoint and allow me to access it so I could begin to learn. But it's not working. Here is some data that I hope is relevant. I am doing all my testing on the SBS 2008 server itself. I changed the hostheader in IIS to reflect an external FQDN I plan to deploy. The SBS server is remote and there are no domain-connected workstations. If I browse "localhost" SSL, I can get to the site, albeit with a self-signed cert warning. If I attempt to connect via SSL using either the internal FQDN (.local), the External FQDN (.net) or any other permutation thereof, I am prompted for credentials three times but am not allowed access. My account is a domain admin. The site is inaccessible using port 80 whether using localhost, internal FQDN (.local), and external FQDN (.net) Right now, I suspect my problem is within IIS, but I don't know. My plan to publish the sharepoint site to the web so my partner and I can check documents in/out. Can someone help me get started in current direction?

• Apache2.2 not responding on Windows 7 desktop

  - by Adam

  Afternoon! I'm having some trouble with Apache2.2 on Windows 7. For over a year it's been running no problem, but all of a sudden requests have just stopped responding. They don't ever time out, the browser just keeps on waiting for a response, which makes me think it's something blocking communication with Apache. Interestingly though, if I stop Apache the requests fail immediately. The Apache service is running, and using netstat I can see it listening on port 80 as configured: TCP 127.0.0.1:80 0.0.0.0:0 LISTENING If I stop the Apache service, that line disappears. I have an entry within my hosts file for each VHost I'm trying, all pointing to 127.0.0.1. Each VHost is configured to *:80. Nothing however is getting recorded in the access or error (at debug level) log files. I've verified the file paths are correct, even though they were never changed. Neither is anything getting recorded within Windows' Event Log. The problem showed up when I added a new VHost and restarted, however I hadn't been using it for a couple of days prior so I don't believe it's the config change. I have performed a syntax check to be sure, and when starting from the command prompt no errors are reported there. I do have Windows Firewall running, however I've verified the Apache rule is correct and tried turning it off to ensure that wasn't the problem. I've reinstalled Apache, in the hope it might magically fix something using the default config, but still no joy. I've also tried using a different port. I'm completely lost for ideas now. Can anybody help? Cheers Adam

• Directory directive: AuthType None but still need an AuthProvider?

  - by Steffen Winkler

  For now I just need the server to let me download files from one specific folder (in my case I chose /opt/myFolder for that task) Distribution is Debian 6.0 *edit_start* Apache version is 2.4, according to their official documentation, the Order/Allow clauses are deprecated and should not be used anymore I'm an idiot: Apache version is 2.2. *edit_end* My directory directives in apache2.conf look like this: <IfModule dir_module> DirectoryIndex index.html index.htm index.php </IfModule> ServerRoot "/etc/apache2" DocumentRoot "/opt/myFolder" <Directory /> Options FollowSymLinks AuthType None AllowOverride None Require all denie </Directory> <Directory "/opt/myFolder/*"> Options FollowSymLinks MultiViews AllowOverride None AuthType None Require all allow </Directory> When I try to access a file inside that folder (http://myserver.de/aTestFile.zip) I get an Internal Server Error. Also Apache writes the following error into it's log: configuration error: couldn't check user. Check your authn provider!: /aTestFile.zip Why would I need an authn provider if I don't want any authentication? Also I hope someone can explain to me what kind of AuthenticationProvider I'd need for that. Everytime I search for those things I get pointed at people asking how to protect files/directories with passwords or restrict access to some IP addresses, which doesn't really help me. ok, since I've Apache version 2.2, here is the error I get when using the Order/Deny/Allow commands instead of AuthType/Require: Invalid command 'Order', perhaps misspelled or defined by a module not included in the server configuration.

• All websites migrated from server running IIS6 to IIS7

  - by Leah

  Hi, I hope someone will be able to help me with this. We have recently migrated all of our clients' sites to a new server running IIS7 - all the sites were originally running on a server running IIS6. Ever since the migration, lots of our clients are reporting error messages. There seems to be quite a number of issues related to sending emails and also, we have had the following error message reported by several different clients: Server Error in '/' Application. -------------------------------------------------------------------------------- Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Web.HttpException: Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. I have read elsewhere that this error can appear if a button is clicked before the whole page has finished loading. But as this error has now appeared on multiple sites and only since the server migration, it seems to me that it must be something else. I was wondering if someone could tell me if there is something specific which needs to be changed for .NET sites when sites are moved from a server running IIS6 to a server running IIS7? I don't deal with the actual servers very much so I'm afraid this is very much a grey area for me. Any help would be very much appreciated.

• Either, nginx+php-fpm bad config or nginx+php-fpm cannot handle high query?

  I have wordpress installed in my server configured(hopefully with nginx+php-fpm+mariaDB). I am trying to import using wordpress importer a 1.5MB xml file. Everytime I try to upload it using the importer, it got cut of... meaning just blank screen result.. Here is my error log: actually I just posted 2 of the errors [error] 858#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: xx.xxx.xx.xx, server: xxx.com, request: "GET xxxx.html HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "xxx.com" [error] 858#0: *13 connect() failed (111: Connection refused) while connecting to upstream, client: xxx.x.xx.xx, server: xxx.com, request: "GET xxxx.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "xxx.com" I don't know what is the reason why it can't process the wordpress export .xml. I already increased max_file_upload & etc., but nothing happens. Hope somebody can help me.

• Redmine plug-in fails at rake db:migrate_plugins

  - by Drew

  Hey, First post, so hope I'm in the right place. While trying to install the Redmine plug-in 'Wiki Extensions', I keep getting stuck when I try to run the "rake db:migrate_plugins RAILS_ENV=production" command. I am moving server and I'm in bit over my head. Haven't found anything on Google that has helped me much, though I might have missed something. I have pasted in the output with --trace: (in /srv/www/vastpark.org/redmine) ** Invoke db:migrate_plugins (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute db:migrate_plugins Migrating engines...

• Edit-text-files-over-SSH using a local text editor

  - by Mikko Ohtamaa

  I am working in various Linux and UNIX environments. I'd like to elegantly solve the problem of editing remote configuration files over SSH. Instead of using terminal editors (nano), I'd like to open the file in a local text editor on my desktop (Sublime Text 2). CyberDuck, WinSCP and various other SFTP apps can do this. Using editors over X11 forwarding has also proven to be problematic. Also using archaic text editors like Vim or Emacs do not serve my needs well. They could do this, but I prefer using other text editing software. Using ssh mounts (FUSE) are also problematic unless they can happen on the demand and triggered by the remote site. So what I hope to achieve Have a somekind of easily deployable shell script etc. which I can copy to remote server (let's call it mooedit) I run mooedit command on the remote server of which I have connected over SSH connection mooedit sends some kind of signal (over SSH( to my local desktop On my local desktop this signal is captured and it determines 'a ha! moo wants to edit a file on server X in folder Y' File is SFTP transfered to the local desktop (/tmp) File is opened in a nice GUI text editor on the local desktop When Save is pressed, the local desktop notices changes in the file and SFTP sends the resulting file back to the server The question is: What signaling mechanisms SSH provides for this? Any other methods to trigger a local text editor for remote SSH file?

• Windows XP over two monitors, but one of them switches off at boot... how to fix? How to switch bac

  - by jae

  When booting into XP (x64, Athlon II X2 245, 4GB RAM), my main monitor (got two 19" TFTs hooked up, two gfx cards, a 4650 (1GB, the primary monitor's on this) and a 4350 (512MB)) switches off. Logging in blind (cursor down key, typing password) gets me one screen, the secondary. Booted correctly until about two days ago. No clue what's the cause, last change was (if I don't overlook something) installing the ATI 9-12 hotfix. And booting into Windows 7, after returning from 7, it was like this. For some weird reason, I cannot start Catalyst Control Center (I right-click desktop, choose the CCC entry, the pointer changes to hourglass for a half-second... and nothing. Likewise with "Properties"... I think, as all windows open on the primary (off) screen, and no entry appears in the task bar for Properties) Completely stumped. Windows 7, same setup, works w/o a hitch. The primary monitor appears to run in some unknown, but pretty low, resolution, as the mouse pointer only moves onto it at about half-height. But, w/o CCC or display properties, I cannot check. And, obviously, not change anything. Hope this was not too long-winded. And I'm sure I still forgot essential stuff. :P

• APC Smart UPS network shutdown issue

  - by Rob Clarke

  Here is a bit about our setup: We have 2x Smart-UPS RT 6000 XL units with network management cards We are running Powerchute from a network server Powerchute is connected to the management cards of both UPSs UPSs are set to do a graceful shutdown via Powerchute when the battery duration is under 20 minutes We also have a command file that runs with Powerchute Although our setup is redundant we do not have an equal load on each server due to APC switches for single power devices The problem is that as we do not have an equal load on each server the batteries drain at different rates. This means that the UPSs both get to the specified low battery duration at completely different times. The problem here is that UPS 1 may have run down to 5 minutes and is in desperate need of initiating a Powerchute shutdown - UPS 2 still has 25 minutes of runtime so no shutdown is initiated. Consequently UPS 1 goes down and takes all the servers with and then shuts down UPS 2 as well! What we need to happen are 1 of either 2 things: Powerchute initiates the shutdown as soon as either UPS reaches the 20 minutes low battery duration setting - and doesnt wait for both The UPS with the heavier load expends its entire battery but does not shutdown both UPSs and lets the load be switched across to the UPS that still has runtime remaining. That way when the UPS that still has runtime reaches its low battery duration it can proceed with the graceful shutdown via Powerchute. Hope that makes sense, any help is greatly appreciated!
