• Windows is very slow with my new SSD

  - by Maksym H.

  I have a laptop HP probook 4520s with Core i5 M480 @ 2.67Ghz, 4Gb RAM, 640 GB HDD Radeon HD 6370m 1GB video card. It would seem like a good stack for work, right? But My HDD has crashed after everyday walking with laptop about 1 year. After buying my new SSD (Patriot memory - Torqx II 128 Gb SATA II) and installing new Windows 8 from scratch - it was amazing fast. But I had only install windows updates, and I feel that the speed become the same as my old HDD, after install other software for my work, it becomes so slow, so when I use my PC with old lower configuration and it really works better than my awesome laptop... I checked that TRIM and AHCI mode are turned on. So why's that? I asked for help in Patriot Memory support, they suggested to send them ATTO test results, done, sent. Here is the response: "Thank you very much for the attached results. Looking at the results, I can see that your SSD speed is a lot lower than it should be. Can you tell me your system specs?" Until they checked my email, I re-installed Windows 8 to Windows 7 and it was again perfect, but the story repeats it becomes slower and slower after every installing new software. Check out some screenshots.. (sorry for the screenshot with russian TaskManager, I hope you will recognize those parameters accordingly with your english or other lang TaskManager) So the main issue that something everytime loads the disc on 100% and the response time is jumping around 1000-3000 ms. Why am I asking about Windows? Because I tried to install Linux Mint (x86) and It just flies. So great performance independent on how many programs I have installed. Only Windows (any 7 or 8) has this problem. So guys, I appreciate any ideas about how to fix that and may be answers of main question - "why is it so.?" Thanks!

• Sync desktop Mac environment to laptop

  - by Andrew Vit

  I spend the majority of my time working at my desktop Mac, which I have configured for my web development environment. My spouse has a MacBook for casual use, and I occasionally steal it back when I need to work off-site, or when travelling. The question is how to best synchronize the two so I can switch between them more readily. I've solved a few obvious things by using online services: Email is hosted on IMAP. Working files are in Dropbox. Source code is managed in git. However, the following are things I always miss when jumping on the laptop: Installed Applications (current versions) Installed libraries & utilities (/usr/local) Apache VirtualHosts & other configurations (/etc) Disk image files for VMs My current method is to connect the MacBook via Firewire target mode and rsync the /Users/me home directory, and then cherry-pick the other items I need from Applications, /etc and /usr/local. The problem with this method is that it can be very time consuming due to things like my virtual machine image files, cached emails, etc. How can I make this faster & easier? Can you recommend a solution for configuration management (so I can repeatably install & configure the same software on both), or synchronization (so I can bring the MacBook up to date nightly, over our home network)?

• IPTables Rule for Google Apps SMTP

  - by XpresServers

  I am trying to add iptables rule to allow traffic on ports 465 & 587 to google apps smtp servers. But I got not luck.

• How do I batch-downsize images on linux, while keeping small images small?

  - by Gabriel

  I have a whole lot of photos and it's time to clean up the mess and free some disk space. I know mogrify is great to batch-resize things down. The problem is, in some directories I have small images mixed with the big ones. I'd like to batch-downsize all the big one but not upsize the small ones. As an example, I have a rep with tens of MBs-pictures in the 3000x2000s. Some of them I have already downsized so I could email them. They may be 1024x768. I'd like to downsize the big ones to 1600x1200, a disk-space-to-quality tradeoff I like. But then, with mogrify or convert, the small ones will be upsized, which would be a waste of disk space. I found some tricky ways to use identify with cut and some scripting to filter the small pics out and mogrify the others, but man, there's got a way to tell mogrify not to upsize my pics... How ? Is there some other tool better suited ?

• Small office network setups

  - by user39822

  I work at a small office and we're overhauling our network setup there. We're a web dev company and at the moment we have 50+ production sites running on the same machine that runs our internal email, which is just plain stupid. We're moving all our client hosting off site and are now looking for something to run our internal office requirement. Below is a brain dump: Equal amount of Mac & PC, about 25 machines in total. We need a central "server" to host files that should be accessible everyone as a "network drive". If possible we'd like to use low cost hardware for this (Mac or Win based). Disk space should be upward of 1TB. Ideally we should also be able to run a small web server on this machine (LAMP stack) to run some planning and billing applications we wrote ourselves. We need some sort of MS Exchange alternative for things like a shared calendar and especially being able to set Out of Office replies. We have one printer that is connected to the network Setup should be something can preferably be managed easily via a graphical interface and NOT require command line skills. Users want to keep using Apple Mail or MS Outlook After a quick google I came across the Zimbra collaboration suite, can anyone recommend this or any other solution for our office?

• Why would e-mail from our own domain not be forwarded to gmail

  - by netboffin

  To solve a problem with spam on our server we tried to forward e-mail from our dedicated server's mailserver(matrix smtp service) to gmail, but while most e-mails got through e-mail from our own domain all went missing. They weren't in the inbox or spam or anywhere else. We've had to go back to using the old system, which means my boss gets a huge amount of spam. We have a windows 2003 server with iis 6 and the matrix smtp service installed. I've toyed with the idea of installing a mail proxy like ASSP but it looks pretty complicated. We're hosting 20 domains on the server as well as our own which has an online shop whose payment system depends on email. I can't start playing around with complicated solutions when it could have disastrous consequences and I don't know enough to implement them safely. So my question has two parts: Part One: Why can't we forward e-mails from people using the same domain. If our domain was foobar.com then [email protected] can't receive from [email protected], but he can receive from everyone else. Part Two: Is there a really simple server side solution to spam that would work with matrix? For instance popfile?

• Outlook / Gmail 'too many simultaneous connections' error

  - by sam

  I'm just setting up Outlook for Mac, and I'm trying to add a Google Apps application for business email (Gmail). I've set it up correctly (same details worked in Mac mail). But I keep getting two errors, either or just a error asking for the username and password again. Just to confirm the user name and password are correct, although when I go into menu command Tools - Account and look in the password field for that account it's blank. But if I just click cancel on the popup asking for my username password it just continues to get mail in the background for about 30 seconds, before again asking again for the password, or showing the above error which I can click 'yes' to and again it will get the mail. But after 30 seconds it does the same thing. I've got two other accounts set up fine, one a horde account (hosted webmail using POP3) and the other a iCloud .me account running on IMAP. What might be causing this and how I can remedy it? A bit more background: the machine is a MacBook Pro running Mac OS X v10.7 (Lion). Update 2013-11-02 I've updated Outlook to SP3, but I still get the same error.

• Macros in Excel 2010 hangs

  - by Ahmad

  I have a spreadsheet with several macros. Generally, when previously using Excel 2007, a user clicks a button and everything works as expected (calculations, some email sending & file I/O). Typically, the expected run-time is about 90 seconds. The spreadsheet is a xlsm file created with Excel 2007. With Excel 2010 however, the same user process results in a non-responsive excel and forces us to kill excel from the task manager. Some note that I have gathered so far in trying to debug this issue: When monitoring CPU usage, it seems that Excel does start the macro. CPU usage increases as expected to about 47% for a few seconds. Excel.exe than drops to 0% usage and I now have a non-responsive Excel (even after 1 hour). If I set debug break points across modules and different functions and step through the code (after clicking the button) , the process works as expected albeit much slower. To add, there were no exceptions. I am at a complete loss as to what the issue may be. I initially thought it may be the add in that is being used but that was debunked by point 2. This seems to be a very odd situation. I can provide more information if required, but I'm at wits end about the root cause could be. I need help in diagnosing and resolving this issue.

• xauth, ssh and missing home directory

  - by flolo

  We have several servers, and normaly everything works fine, except now... we get a new aircondition installed. This takes 36 hours and for this time almost all servers got shutdown, only 2 remaining servers run for the most important tasks (i.e. accepting incoming email, delivering some important websites, login-server). Everybody was informed that when they need appropiate data from the homedirs they should fetch it before take down. Long story short: Someone realized that he have run a certain program on one of the servers. No Problem, he can remote login into our login server and run the programm there without home directory (binaries are local and necessary information can be copied to the /tmp). That works like a charm until... ... the user needs to run a GUI programm. I find no easy way to make it running, usually ssh -Y honk@loginserver is enough but now the homedirectory is missing and ssh is not able to copy the cookies into ~/.Xauthority (as the file server with the home directories is down). Paranoid as all systemadmins all X-Server just listen locally not on tcp ports, so no remote X connection possible SSH config is waterproof - i.e. no way to set environment variables. My Problem is, that the generated proxy MIT cookie from ssh get lost as the .Xauthority doesnt exist. If I could retrieve it somehow I could reenter it a .Xauthority in /tmp. The only other option (besides changing the config) which came to my mind is, makeing a tunnel (netcat, or better ssh) from the remote host to the loginserver and copy the cookie manually (not sure if it the tcp-unix domain socket stuff works as expected). Any good suggestions (for the future - now our servers are already up)?

• CMD/ADB - Autorun script to search, copy, and paste a file from android system to flash drive

  - by Outride

  I've looked around and can't find anything that answers my question. This is my first question, so any tips or thoughts are welcome, as well as an answer :p As explained in title, i want to create a script that launches, finds a file on android phone, copies it, and pastes it to a flash drive. As of right now, it's a mix of multiple tutorials, trial and error, and I'm at a point of giving up. As of right now, I have a flash drive, loaded with three scripts. As follows: Bold = name of file file.bat @echo off :: variables /min SET odrive=%odrive:~0,2% set backupcmd=xcopy /s /c /d /e /h /i /r /y echo off %backupcmd% "C:\Users\Outride\Desktop\kikDatabase.db" "%drive%\all" @echo off cls invisible.vbs CreateObject("Wscript.Shell").Run """" & WScript.Arguments(0) & """", 0, False launch.bat wscript.exe \invisible.vbs file.bat So far, I had to use android commander, manually go through the directory, find /data/data/kik.android/databases and then copy kikDatabase.db to my desktop. Then run this scrip. Yes i'm trying to pull the database to copy all my email contacts. I use launch.bat, which then makes file.bat invisible due to the invisible.vbs script. What would i need to do now to have the file searched for and copied to the flashdrive? Thanks in advance, i'll be glad to answer any questions if theres any :p just remember that i'm not exactly a tech expert haha EDIT* Cleared junk of prior edits. New - I now have a .bat script to recognize what drive the usb is on, and launch py_cmd (adb shell) This is the current script. pull.bat @echo off :: variables SET odrive=%odrive:~0,2% set launching=start "%drive%\Minimal ADB and Fastboot\py_cmd" echo off %launching% so how could I make it for the .bat or a new script, to type the following "adb pull /data/data/kik.android/databases/ %drive%\All\Database" into the adb terminal? please help! I've been racking my brain over this all night :3

• Understanding Authorized Access to your Google Account

  - by firebush

  I'm having trouble understanding what I'm am granting to sites when they have "Authorized Access to my Google Account." This is how I see what has authorized access: Log into gmail. Click on the link that is my name in the upper-right corner, and from the drop-down select Account. From the list of links to the left, select Security. Click on Edit next to Authorized applications and sites. Authenticate again. At the top of the page, I see a set of sites that have authorized access to my account in various ways. I'm having trouble finding out information about what is being told to me here. There's no "help" link anywhere on the page and my Google searches are coming up unproductive. From the looks of what I see there, Google has access to my Google calendar. I feel comfortable about that, I think. But other sites have authorization to "Sign in using your Google account". My question is, what exactly does that authorization mean? What do the sites that have authorization to "Sign in using my Google account" have the power to do? I hope that this simply means that they authorize using the same criterion that gmail does. I assume that this doesn't grant them the ability to access my email. Can someone please calm my paranoia by describing (or simply pointing me to a site that describes) what these terms mean exactly? Also, if you have any thoughts about the safety of this feature, please share. Thanks!

• Someone used or hacked my computer to commit a crime? what defense do I have?

  - by srguws

  Hello, I need IMMEDIATE Help on a computer crime that I was arrested for. It may involve my computer, my ip, and my ex-girlfriend being the true criminal. The police do not tell you much they are very vague. I was charged though! So my questions are: -If someone did use my computer at my house and business and post a rude craigslist ad about a friend of my girlfriend at the time from a fake email address, how can I be the ONLY one as a suspect. Also how can I be charged. I noticed the last few days there are many ways to use other peoples computers, connections, etc. Here are a few things I found: You can steal or illegally use an ip addresss or mac address. Dynamic Ip is less secure and more vulnerable than static. People can sidejack and spoof your Mac, Ip, etc. There is another thing called arp spoofing. I am sure this is more things, but how can I prove that this happened to me or didnt happen to me. -The police contacted Craigslist, the victim, aol, and the two isp companies. They say they traced the IP's to my business and my home. My ex was who I lived with and had a business with has access to the computers and the keys to bothe buildings. My brother also lives and works with me. My business has many teenagers who use the computer and wifi. My brother is a college kid and also has friends over the house and they use the computer freely. So how can they say it was me because of an angry ex girlfriend.

• Connecting to unsecured wireless network

  - by Sanchez

  I would like to know what information is public and can be intercepted in a non-open, but unsecured wireless network. Moreover, is there anything I can do to make it more "secure", other than using https connection whenever possible. In more details, I recently discovered (with surprise) that the wireless network in my school is actually unsecured. Although not everyone can connect to it (you need a student ID), I am told that certain softwares like Wireshark would be able to intercept the data. Since I have been using the network for all private purposes (email, facebook etc), I do feel quite insecure now and would like to understand the situation a bit better. I installed Wireshark and tried to play with it but all I can see are something alien to me. In any case, all I see seems to come directly/indirectly from my IP address, and I have long thought that usually different computers in the same wireless network would be assigned different addresses. Am I wrong? If not, then I feel very confused about what information is actually being captured (potentially by other users in the network, since I don't think I could capture activities of others in the same network anyway), and whether it's safe to use the network at all. (Gambling on others in the same network showing good behaviour is apparently not an option.) Thank you.

• MS Excel and Access - which is better for reports?

  - by Nat

  Where I work, staff have just started to use a basic table in excel (1 october) to record sales which has about 10 columns (name, client, renewed, discount, paid etc). I record the data (total sold etc) every hour and email it to the manager. Each staff has the their own file on the network which they use constantly for that day (eg. John 08-10.xlsx; John 09-10.xlsx etc) and have been told to save the file after they complete a row with client data. I can see the file (in read only mode) to update the report but I am sure there must be a way of doing an autoupdate of their worksheets in real time. I can link worksheets and workbooks to my main workbook but manually. Does anyone have suggestions on have to do this on Excel? Or would Access allow me to make a report which shows the sales total for that hour without the staff closing the file or constantly clicking save every few minutes? We use office 2010. thanks

• Best Asp.net Hosting

  - by dotnetguts

  There are many asp.net web hosting companies which spends lot on advertisement and also gives you very cheaper rate, as low as $5, but when it comes to support they are simply hopeless. Everyone can you please pass your experience with your past hosting companies and suggest any good asp.net hosting company? Please consider following requirement factors 1) Asp.net 3.5 or 4.0 supported. 2) Url Rewriter support 3) GZip support (Dynamic through code) 4) Initial Setup support (If required) 5) SQL Server 2005 or 2008 6) Allow to access SQL Server DB using SQL Mgmt Studio 7) Environment supporting Backup and Restore of DB on my own, without involving tech support team 8) Full Text Search support 9) FTP support 10) I can able to send atleast 500 Emails daily. 11) 99.9% Up Time (No matter all web hosting say they have 99.9% Up Time, but its not true). 12) Alert Email to be sent when they do any maintenance or during downtime. 13) Hosting Price should be reasonable. Incase you feel i am missing something please add to the list. Can anyone suggest good webhosting company based on above factors?

• should i and how do i backup my database for a webapp that is hosted on amazon ec2 server?

  - by user8184

  I set up an amazon ec2 instance using ubuntu server edition. I install LAMP stack on it. I did up a php web app running on mysql. I have not officially launched, but I need to know this before launching. Should I backup my database data? If so, how should I do it as cost effective as possible? Previously for another web app, i wrote a perl or bash script (cannot remember) that will be executed by cron on a daily basis. The script will then backup the database into a single .sql file and send as email attachment to my gmail account. That web app was on shared hosting hence, I was quite sure i needed to do backup of my database. My files are on git repo so I am not worried about that. Please advise. I am totally unfamiliar with AWS. Only know as much as setting up an account. That is all. Thank you.

• Trouble getting started with the STEALTH monitoring package

  Is anyone here familiar with the Linux-based STEALTH package (for monitoring FS integrity of client systems)?

• NFS-shared file-system is locking up

  - by fredden

  Our NFS-shared file-system is locking up. Please feel free to ask any questions you feel relevant. :) At the time, there are a lot of processes in "disk sleep" state, and the load averages on our machines sky-rocket. The machines are responsive on SSH, but our the majority of our websites (apache+mod_php) just hang, as does our email system (exim+dovecot). Any websites which don't require write access to the file-system continue to operate. The load averages continue to rise until some kind of time-out is reached, but for at least 10-15 minutes. I've seen load averages over 800, yet the machines are still responsive for actions which don't require writing to the shared file-system. I've been investigating a variety of options, which have all turned out to be red-herrings: nagios, proftpd, bind, cron tasks. I'm seeing these messages in the file server's system log: Jul 30 09:37:17 fs0 kernel: [1810036.560046] statd: server localhost not responding, timed out Jul 30 09:37:17 fs0 kernel: [1810036.560053] nsm_mon_unmon: rpc failed, status=-5 Jul 30 09:37:17 fs0 kernel: [1810036.560064] lockd: cannot monitor node2 Jul 30 09:38:22 fs0 kernel: [1810101.384027] statd: server localhost not responding, timed out Jul 30 09:38:22 fs0 kernel: [1810101.384033] nsm_mon_unmon: rpc failed, status=-5 Jul 30 09:38:22 fs0 kernel: [1810101.384044] lockd: cannot monitor node0 Software involved: VMWare, Debian lenny (64bit), ancient Red Hat (32 bit) (version 7 I believe), Debian etch (32bit) NFS, apache2+mod_php, exim, dovecot, bind, amanda, proftpd, nagios, cacti, drbd, heartbeat, keepalived, LVS, cron, ssmtp, NIS, svn, puppet, memcache, mysql, postgres Joomla!, Magento, Typo3, Midgard, Symfony, custom php apps

• Ubuntu server crashes; need help figuring how to figure out why

  - by neezer

  I have a 768 Slice at slicehost.com running Ubuntu Server 8.04.2 LTS (hardy) with a LAMP stack on it that periodically crashes, though why I am not sure. From what I can tell, there is a process that basically goes rogue and consumes all the memory on the slice, suffocating all the other programs running until the whole thing comes to a grinding halt, and I have to do a hard reboot of the slice to get it back up and running again. I can't detect any pattern for this (it seems to happen about once a month, more or less). Here's a screenshot of my console during the last crash: I would assume that a possible cause might a PHP script or an apache configuration rule that might cause the crash if triggered? How would I be able to find out which one is the offending one? I've checked and rechecked all my PHP scripts, and running them doesn't seem to trigger the crash. I've also been able to log on to my system during a crash and see what's running (with top), but I can't tell how the offending process was started, so I can't trace the root of the problem! I know my description is overly generic, but unfortunately my expertise in tracking down the source of these glitches is very limited. If you need any additional information about my system in order to help me figure this out, please let me know in the comments, and I will append it to the question. My only other lead as to the culprit here is Wordpress, which we have installed on this server. Here are the details: Wordpress 3.0.3 with the following plugins installed and activated: Addmarx - Bookmark/Share/Email Dropdown, Akismet, All in One SEO Pack, Animated Banners, Automatically publish highlights of any website, directly to your Blog, Broken Link Checker, CMS Dashboard, Collapsing Categories, Status Updater, SubHeading, Ultimate Google Analytics, VastSubCat, WP-CMS Post Control, and WP Super Cache

• Redirection of outbound UDP port NTP.

  - by pboin

  For my residential service, I changed ISPs to Zoom/Armstrong. Just after that, my NTP daemons stopped working. I dug deep and diagnosed the problem: Unprivileged ports are getting out. When i run 'ntpdate' for example, I go out on a high, unprivleged port, and get a response on UDP 123. That's fine. The 'ntpd' daemon though, expects to go out on 123 and get its reply there as well. This must be a common problem, because it's directly addressed in the NTP troubleshooting guide. Just to see what would happen, I wrote a detailed email to the general support address at Armstrong. They replied almost immediately with a complete technical answer! They have everything <1024 blocked, except for a few ports to support outbound VPN. So, the question: Can I use IPtables to essentially re-write my outbound UDP 123 up to 2123 or something like that? If I do, does there need to be a corresponding 2123-123 rule to translate the reply? This seems like NAT, but with ports, not addresses. True, I could run ntpdate from cron, but that loses all of the adjustment smarts of NTP.

• Exchange 2003 -- Mailbox Management not deleting ALL messages aged 30 days or older...

  - by tcv

  I've recently created a Mailbox Management task within Exchange 2003 that, every night, looks at the contents of the Deleted Items within a particular mailbox and deletes mail that's 30 days or older. The scheduled task ran on its own last night and I have confirmed that messages within the right mailbox and the right folder were, in fact, processed. Many mails were deleted ... but not never email older than 30 days. In fact, the choice seems kinda random. Last night 3/10/2010 was the 30 day watermark. Mails were deleted from 3/10/2010, sure enough, but not all of them. Mails older than 3/10/2010 were deleted as well, but, again, not all of them. The only criteria I have on the management -- aside from the single mailbox and single folder scopes -- is the age criteria. The size criteria is set to Any, meaning I don't care about the size. I care about the age. It's made me wonder where there is some sort of limit on how many mails can be processed? The schedule is set for 12am and 1am every night. Any hints appreciated.

• Azure Virtual Machines - what fault tolerance do they provide?

  - by Borek

  We are thinking about moving our virtual machines (Hyper-V VHDs) to Windows Azure but I haven't found much about what kind of fault tolerance that infrastructure provides. When I run VHD in Azure, I've got two questions: Is my VHD and all the data in it safe? I think that uploaded VHDs use the "Storage" infrastructure so they should be automatically replicated to multiple disks and geographically distributed but should I still make a full-image backup just to be safe? (Note that of course I will be backing up the actual data inside VMs that I care about; I just want to know if there is a chance greater than 0.0000001% that one day I will receive an email from Microsoft telling me that my VM is gone and that I should create or restore it from scratch). Do I need to worry about other things regarding the availability of my VMs? I mean, when I have an on-premise server I need to worry about the hardware itself, about the host operating system, what would happen if my router failed, if my Hyper-V's C: drive failed etc. Am I right in thinking that with Azure, their infrastructure takes care of all of this? Thanks.

• Parallels 6 - Is It Just Me or Does It Run Really Slowly?

  - by 5arx

  I've been running Parallels since version 2 with great success. I use it as my .Net development environment and over the last few years have converted so many others to the Parallels/Mac way of doing Windows/.Net development that I feel I should be getting perks/gifts and/or freebies from Parallels Corporation ;-) A month or so ago I upgraded to version 6 and ... immediately wished I hadn't. I'm currently running it on a laptop - a 2009 MacBook Pro (13"/2.53Ghz/4GB) while my MacPros at work and home are still running v5. I have seen nothing in v6 that makes me want to upgrade the install on those. The general problem is performance - upon starting or suspending a vm (always Windows 7 Ultimate), OS X slows down, quite often freezing for a minute or two at a time. The performance of the vms themselves are fine, but for me the point of this set-up is to be able to do web-browsing, email checking etc. on the OS X side of things while doing the stuff that can only be done on Windows (Visual Studio, SQL Server tools) on Windows. I have been using Parallels for a while so at least feel like I know what I'm doing so at the moment I am heading towards forming an opinion that its Parallels thats to blame. I've tweaked and tweaked all the vm configuration properties but to no avail. Support emails to the company have all received replies - there are no documented case of the issue you mention. Has anyone else seen this problem and if so, have you found a fix?

• Debian Server wont reboot from script

  - by Littlejon

  I have a script that is run to backup a server via Rsync, after that script is run I want the server to reboot. My script is run as root from the Crontab at 3am in the morning. #!/bin/bash HOST="email" RSYNC_OPTS="-a -v -v --progress --stats --delete" RSYNC_DEST="10.0.0.10::$HOST" BACKUP_LIST="/etc /home /root" TIMESTAMP="/timestamp-bkup-start.chk" TIMESTAMP2="/timestamp-bkup-stop.chk" touch $TIMESTAMP rsync $RSYNC_OPTS $TIMESTAMP $RSYNC_DEST for BACKUP_ITEM in $BACKUP_LIST; do rsync $RSYNC_OPTS $BACKUP_ITEM $RSYNC_DEST done /etc/init.d/zimbra stop sleep 60s rsync $RSYNC_OPTS /opt $RSYNC_DEST touch $TIMESTAMP2 rsync $RSYNC_OPTS $TIMESTAMP2 $RSYNC_DEST echo `date +%Y%m%d%H%M` >> /var/log/reset reboot # $# shows number of args passed # $1 to access first variable #if [ $# -eq 1 ]; then # if [ $1 = "withreboot" ]; then # echo "rebooting..."; # echo `date +%Y%m%d%H%M` >> /var/log/reset # /sbin/reboot # fi #fi I have tried using init 6 rather then reboot. I have tried /sbin/reboot. I also have another basic script that just echos to the reset log and runs reboot without issue. It is just with the script above the server wont restart. If anyone has any theories that would be great as I have run out of idea. Thanks, Jon

• how to diagnose a hard system seizure? Dell+Ubuntu

  - by rob

  I've got Ubuntu 9.10 on a Dell Vostro 420 desktop, a little over a year old, which I use for plain vanilla work stuff (email, web, terminal, text editor). Every now and then, at totally random times, it completely freezes on me. Hard. Mouse and keyboard stop working, cursor stops blinking, clock stops moving. All I can do is hold down the power button on the front of the box to shut it off. Sometimes it happens after several months of continuous uptime; sometimes it happens a few minutes after a reboot, while all I've done is open a terminal to look at log files, or maybe firefox to do a google search. Each time, there is nothing at all in /var/log/messages at the time of the crash. This makes it seem like a hardware problem, and indeed a few months ago I opened the box and wiggled everything and the problem went away for a while. But now it's back. I went in and checked everything, took out each RAM card and reseated. No luck. I ran all the system diagnostics (the long version) and everything passed with flying colors. Something is messed up in this box, but without any useful logs or failed tests, how in the world am I going to find it? And of course, Dell's not gonna help me cause I went and replaced Windows with Ubuntu. What steps would you take next to track down this problem?
