• Command window missing default 8x12 font

  - by Robert Koritnik

  Installation: Windows Server 2008 R2 Remote Desktop Service role When I logon locally my command window (cmd.exe) displays with default font that is 8x12. But when I logon remotely and open command window, it opens with the smallest possible font selection. Opening window properties and setting font size, the default 8x12 font is missing from the list. What should I do to get this font back in the list? Following screenshots show settings when logged on locally and remotely. Local machine is not Aero capable, but remotely I can have Aero environment. I've also tried setting it to basic, but there was no change. Local logon Remote logon

• Ubuntu server failing daily

  - by deanvz

  Symptoms: Server becomes unresponsive - Increase in load, all services stop Loss of connectivity - Ping/SSH Flush MySQL hosts after reboot - As MySQL refuses new connections Intermittent Apache crashes Generally happens early morning hours - 2 days of the week are however excluded Changes made: Updated the OS - to Ubuntu 10.04.4 LTS Not sure if the MySQL server was also updated in the process Current MySQL version - mysql Ver 14.14 Distrib 5.1.63, for debian-linux-gnu (x86_64) using readline 6.1 Updated Plesk from 10.4.4 Update #47 to 11.0.9 Update #23 Rebooted on almost daily basis All crons stopped for the times corresponding to the server crashes Created a MySQL log to monitor the lock times on queries Possible causes: Failing hardware Incorrect software configuration (MySQL, Apache etc) Responsibilities: Small webserver Runs our billing system - WHMCS Responsible for CRONs Bulk-email solution - No delivery times coincide with server crashes Proposed solutions: Move machine over to VM Format and restore the Plesk server backup and take it from there? Side notes: Seems to be a general Apache failure across all our linux servers - Intermittent problem Are we doing something fundamentally wrong in the Apache config? (I understand that this is a secondary question, just making sure that it isnt possibly holding any relevance)

• Increasing FreeBSD threads

  - by sh-beta

  For network apps that create one thread per connection (like Pound), threadcount can become a bottleneck on the number of concurrent connections you can server. I'm running FreeBSD 8 x64: $ sysctl kern.maxproc kern.maxproc: 6164 $ sysctl kern.threads.max_threads_per_proc kern.threads.max_threads_per_proc: 1500 $ limits Resource limits (current): cputime infinity secs filesize infinity kB datasize 33554432 kB stacksize 524288 kB coredumpsize infinity kB memoryuse infinity kB memorylocked infinity kB maxprocesses 5547 openfiles 200000 sbsize infinity bytes vmemoryuse infinity kB pseudo-terminals infinity swapuse infinity kB I want to increase kern.threads.max_threads_per_proc to 4096. Assuming each thread starts with a stack size of 512k, what else do I need to change to ensure that I don't hose my machine?

• How to disable the second partition without unmount it in Mac?

  - by bagusflyer

  I've installed OSX Yosemite in another partition in my Mac. But there is a problem. For example, I installed iBooks in both partition. When I right click one of my epub or pdf file, both iBooks are shown in my context menu. This is not what I want. What I want is to only allow the apps in Yosemite shown. Of course I can disable apps in my old Maverick partition by unmount the volume. But again this is not what I want because it will hide the partition when I boot my machine so that I can't boot up into my Maverick partition. Can anybody advise if there are any better ideas? Thanks

• Determining who is running with administrator rights?

  - by Alex C.

  I work at a small non-profit organization with about 55 desktop PCs running Windows XP Pro. The domain controller is running Windows Server 2003. I have a two-part question (note that I'm a bit of a newb when it comes to network administration). Part 1: Is there some simple way that I can determine which accounts are logged in with administrator rights? Part 2: Is there a way that I can remove administrator rights from users without sitting down at each individual machine? Thanks for considering my questions.

• AWS RDS MySQL remote connection extremely slow

  - by nute

  I have a site hosted on AWS EC2 (Elastic Beanstalk), with a MySQL database hosted on AWS RDS. Everything works fine on the production server, fast and all. However when I try to connect remotely from my local machine, it sometimes gets extremely slow (like 4 minutes to load the list of tables), or simply times out. I added my IP in the security group (which I did correctly, since it sometimes works). When it doesn't work, I at the same time check the prod server and it still looks good.

• How to improve battery life on Samsung 13.3” Series 7 Ultra (NP730U3E-S01AU)?

  - by beam022

  Recently I've bought a Series 7 Ultra Samsung ultrabook and decided to change the OS from originally installed Windows 8 to Ubuntu 14.04LTS. However, it's difficult not to notice great decrease in battery life: on pre-installed Windows 8 battery would last for about 6 hours while on Ubuntu it's almost empty after 2 hours of same kind of work (wi-fi, web, vlc, spotify, intellij idea). I'm not here to say that Ubuntu's battery performance is worse than Windows, but to ask for suggestions how to improve the situation (2 hours of work is pretty poor battery life). Can you recommend some sources, applications or tips/tricks that would improve battery life on my ultrabook? I really like the Ubuntu experience, but this makes my machine much less reliable. I suspect that graphic video card might be one of the issues here. Let me give you tech specs of the ultrabook: Processor: Intel® Core™ i5 Processor 3337U (1.80GHz, 3MB L3 Cache) Chipset: Intel HM76 Graphic: AMD Radeon™ HD 8570M Graphics with 1GB gDDR3 Graphic Memory (PowerExpress) and Intel(R) HD Graphics 4000 Display: 13.3" SuperBright+ 350nit FHD LED Display (1920 x 1080), Anti-Reflective Memory: 10GB DDR3 System Memory at 1,600MHz Hard-drive: 128GB Solid-state Drive More informations here, on the official page. If it's helpful to provide additional info, I'm happy to do it, just let me know what you need. Thank you.

• Postfix relay to multiple servers and multiple users

  - by Frankie

  I currently have postfix configured so that all users get relayed by the local machine with the exception of one user that gets relayed via gmail. To that extent I've added the following configuration: /etc/postfix/main.cf # default options to allow relay via gmail smtp_use_tls=yes smtp_sasl_auth_enable = yes smtp_tls_CAfile = /etc/ssl/certs/ca-bundle.crt smtp_sasl_security_options = noanonymous # map the relayhosts according to user sender_dependent_relayhost_maps = hash:/etc/postfix/relayhost_maps # keep a list of user and passwords smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd /etc/postfix/relayhost_maps user-one@localhost [smtp.gmail.com]:587 /etc/postfix/sasl_passwd [smtp.gmail.com]:587 [email protected]:user-one-pass-at-google I know I can map multiple users to multiple passwords using smtp_sasl_password_maps but that would mean that all relay would be done by gmail where I specifically want all relay to be done by the localhost with the exception of some users. Now I would like to have a user-two@localhost (etc) relay via google with their own respective passwords. Is that possible?

• Fried graphics card, how to proceed ?

  - by user19496

  Motherboard: Biostar TPower I45 I fried my graphics card (white smoke), by removing the cable marked PCI-E from the card, and then booting. Removed the graphics card, and now the machine is booting, and I can ping it. However I have no possibility to see what is actually happening, because I can't attach a monitor. Can I workaround the lack of monitor in some way, just to see if the motherboard is fine, attach a cable and telnet in or any other way ? Or, do I have to buy and install a new graphics card to be sure ?

• an unknown ip on network

  - by Ahmed safan

  In our office we have many PCs, all of them have static IP addresses. We had a problem with one server with ip 192.168.1.10 dropping off the network occasionally. I unplugged the network cable from the server and from pinged 192.168.1.10 from another host and there was a response. I searched all PCs to see if any has such ip but i didn't found a one. I changed the server ip to fix the problem, but I still find this rogue device using 192.168.1.10 on the network -- how can I figure out what it is? Could it be the ip of virtual machine on someone's PC?

• nginx + php-fpm “504 Gateway Time-out” after compiling with curl support

  - by Brian

  We recently switched to managing php with php-fpm. It was working great, but is now giving me issues. The most recent change was to install libcurl-devel and re-compile php (5.3.3) using --with-curl. Now I'm getting 504 timeouts with nginx and the pages won't load. HTML pages load fine, phpinfo() loads as well. Tried backing out the changes and re-compiling without curl support, but still not having any luck. Also tried adjusting request_terminate_timeout per some of the other posts here on SF without change. This is on a test machine that has no other clients hitting it. I also tried switching to unix socket instead of tcp--same result. What am I missing here? Am I barking up the wrong tree with curl?

• pecl_http extension not loading

  - by Tegan Snyder

  For some reason pecl_http extension is not showing up in my test.php file with contains: <?php phpinfo(); ?> I just installed pecl_http using: pecl install pecl_http The install was successful and I verified it by running: pecl list Installed packages, channel pecl.php.net: ========================================= Package Version State mongo 1.2.10 stable pecl_http 1.7.4 stable I then located my php.ini file using: php -i | grep 'Configuration File' Configuration File (php.ini) Path => /etc/php5/cli Loaded Configuration File => /etc/php5/cli/php.ini I edited it in vim and added: extension=http.so Finally I restarted Nginx and PHP-FastCGI: /etc/init.d/nginx restart /etc/init.d/php-fastcgi stop /etc/init.d/php-fastcgi start My PHP extension_dir is : /usr/lib/php5/20090626 I verified that "http.so" is located in that directory. Any ideas why it's not loading? My machine is running a Ubuntu 10.04 LTS 64bit Profile on Linode. The only other extensions I have installed are New Relic and Mongo. Thanks!

• Raleigh theme on LightDM, Ubuntu desktop, Nautilus window, menus & menu-bars

  - by Tassos Seligkas

  After performing an upgrade from Natty to Oneiric, I had a problem similar to the one reported in here at every system boot: Desktop forgets theme? Everything, from the LigthDM greeter to the ubuntu desktop used the ugly raleigh theme, apart from firefox, thunderbird few other applications after logging in. Unfortunately none of the solutions suggested in the topic above worked for me. The only way I could get acceptable appearance would be to switch to gnome at login and using the Adwaita theme. The lightdm greeter still uses the raleigh theme though. Unfortunately, I tried some "brute-force" methods by reinstalling (sudo apt-get install --reinstall) ubuntu-desktop, unity, unity-common, unity-greeter, gnome-session, gtk2-engines. I also tried moving .config, .gconf, .gconfd, .gnome, .gnome2 to a backup dir to reset account desktop preferences. None of the above solved the issue. On the contrary, logging-in to Ubuntu setup does not show unity and window decorations anymore. My fallback remains the Gnome logon and the Adwaita theme. This is my workstation machine I am hosting Ubuntu on, so, though possible, it is time consuming to perform a backup and format-reinstall ubuntu 11.10. Could you please let me know if I can get an alternative way of repairing my ubuntu desktop? (I believe it all started when, during the 11.04-to-11.10 upgrade, the installation of downloaded packages for oneiric broke when nautilus-dropbox failed to access the dropbox servers - I am behind a proxy but with proper proxy settings had no problems using apt-get & synaptic. However I removed dropbox and resumed partial installation on second boot.)

• grep pattern interpretted differently in 2 different systems with same grep version

  - by Lance Woodson

  We manufacture a linux appliance for data centers, and all are running fedora installed from the same kickstart process. There are different hardware versions, some with IDE hard drives and some SCSI, so the filesystems may be at /dev/sdaN or /dev/hdaN. We have a web interface into these appliances that show disk usage, which is generated using "df | grep /dev/*da". This generally works for both hardware versions, giving an output like follows: /dev/sda2 5952284 3507816 2137228 63% / /dev/sda5 67670876 9128796 55049152 15% /data /dev/sda1 101086 11976 83891 13% /boot However, for one machine, we get the following result from that command: Binary file /dev/sda matches It seems that its grepping files matching /dev/*da for an unknown pattern for some reason, only on this box that is seemingly identical in grep version, packages, kernel, and hardware. I switched the grep pattern to be "/dev/.da" and everything works as expected on this troublesome box, but I hate not knowing why this is happening. Anyone have any ideas? Or perhaps some other tests to try?

• Insulate hosted client domains from server IP address change?

  - by babtek

  I will be hosting web content for many client domains on a single IP address (with a web hosting company, not inhouse machine). Initially, I must give client some information to configure their registrar to point the domain to my server. I want client domains insulated from a potential IP address change, so if I change hosts/IP address they don't have to reconfigure anything with their registrar. Is this reasonably possible without running my own nameserver? If so, what would be the smartest way to make it happen? Instruct clients to make CNAME record? Use some type of DNS management service that clients would use as a nameserver?

• DNS updating issue

  - by Will

  Hey guys, I'm new to serverfault so please excuse me if I sound a tad nub. I work in an environment that is kinda peace mealed together, and I honestly don't know how it works. I'm new to the IT field and am still in school. When I replace a PC I rename the old one to mo-o-pcname and give the new one the proper name of mo-pcname (mo is a location thing we use so it really doesn't apply to the problem.) The new PC will function on the network; it will have the ability to access network resources (printers, file shares, etc) and it will have the ability to get out to the internet. However I can no longer ping the machine. It would appear as if the DNS (A) record is not getting updated or something. Like I said I'm kinda new to the field and just trying to work through this problem. Thanks for your help.

• OS X Snow Leopard fails to boot after upgrade to 10.6.1

  - by pixeline

  I'm a fairly recent mac user. Been using windows for decades and happily switched. But i upgraded from 10.6 to 10.6.1 last night and the upgrade looks like it failed. I restarted the machine when it asked to then went to bed. In the morning the computer was still trying to shut itself off. So i forced the shutdown, restarted, but now i'm stuck with the loading spinner. What can i do? UPDATE: Verbose didn't show anything interesting. i also did the hardware test. Nothing comes up wrong. Disk utility did not find any error on the HD. But, it did show a fatal error when checking permissions.

• Exalogic&ndash;The One Day Installation Challenge

  - by james.bayer

  It’s a really exciting time for the extended WebLogic community as we are enjoying seeing the impressive results of Exalogic deployments.  At Oracle Open World, a lot of people I spoke with came away impressed with the raw performance.  However, Exalogic offers a lot more than just raw performance.  I had the pleasure of working with Ram Sivaram during one of the Exalogic training sessions in Santa Clara.  In this video diary, he shows the Exalogic machine arrive on the shipping dock, get unpacked, wired up, powered on, configured, and installed with a WebLogic Server cluster in just about 10 hours.  I’ve worked with customers in the past that have taken several weeks or longer to get an environment ready after the hardware arrives.  This typically involves many different specialized teams in their organization.  Mohamad Afshar just wrote a great explanation of the benefit of Engineered Systems and contrasting that to the status quo.  Being able to streamline deployment of middleware capacity will have a lot of value for customers shortening time to deployment.  Thanks for the video Ram, you’ve set a high bar, we’ll see if anyone can top your time!

• IIS FTP service - download timeouts and restarts getting the data twice

  - by accel229

  We have an IIS FTP site on a Windows Server 2003 x64 machine. Application Layer Gateway service is disabled (so http://support.microsoft.com/kb/931130 does not apply). Windows Firewall service is disabled as well. Connection timeout for the FTP site (there is only one) is set to 1,200 seconds = 20 minutes. An external client can connect to the site, list directory contents and download small files. When a client attempts to download a large file (eg, if the download continues for 3 minutes, which is still under 20 minutes, but relatively long), the server sends all data, then the connection times out, the client issues REST / RETR commands attempting to restart the download since after the last byte (which I believe should succeed and receive exactly 0 bytes), and the server behaves as if the client tried to restart after byte 0, that is, it sends the entire file all over. Any ideas on how to fix this?

• Apache w/out internet connection

  - by robert knobulous

  I have a Vista laptop that I have been running Apache / MySql / Php / PhpMyAdmin on for quite some time without fail. I just use it to test bits of code here and there etc. No problems, until recently when I needed to test something and I happened to be in a place that I could not get an internet connection. Why am I unable to access localhost from the same machine without an internet connection? I am type http://localhost..etc into the browser's address bar and I get the message that I am unable to access without an internet connection. I checked my windows/system32/etc/hosts file and the first two lines are 127.0.0.1 localhost ::1 localhost What am I missing here?

• rake aborted! undefined local variable or method

  - by Subhransu

  In a fresh new Ubuntu machine, I have installed ruby with sudo apt-get install ruby1.8 and then installed rubygem1.8 with : sudo apt-get install rubygems and after that installed rails3.2.8 with : gem install rails The procedure was very simple. But here comes the problem. When I tried checking the version of rake with rake --trace -version I got the following error: rake aborted! undefined local variable or method `rsion' for #<Rake::Application:0xb72c731c> /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:316:in `standard_rake_options' /usr/lib/ruby/1.8/optparse.rb:1298:in `eval' /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:316:in `standard_rake_options' /usr/lib/ruby/1.8/optparse.rb:1298:in `call' /usr/lib/ruby/1.8/optparse.rb:1298:in `parse_in_order' /usr/lib/ruby/1.8/optparse.rb:1254:in `catch' /usr/lib/ruby/1.8/optparse.rb:1254:in `parse_in_order' /usr/lib/ruby/1.8/optparse.rb:1248:in `order!' /usr/lib/ruby/1.8/optparse.rb:1339:in `permute!' /usr/lib/ruby/1.8/optparse.rb:1360:in `parse!' /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:425:in `handle_options' /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:74:in `init' /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:133:in `standard_exception_handling' /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:72:in `init' /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:64:in `run' /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:133:in `standard_exception_handling' /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:63:in `run' /var/lib/gems/1.8/gems/rake-0.9.2.2/bin/rake:33 /usr/local/bin/rake:19:in `load' /usr/local/bin/rake:19 Is it the problem due to I have installed straight from ubuntu apt-get package manager ?

• Performance difference between MacBook Pro (2.8 GHz) vs Air (1.7 GHz)?

  - by jonathanconway

  I'm comparing these two Apple laptops: MacBook Pro (13", 2011 model): 2.8GHz dual-core Intel Core i7 processor with 4MB shared L3 cache 4GB (two 2GB SO-DIMMs) of 1333MHz DDR3 SDRAM AMD Radeon HD 6770M graphics processor with 1GB of GDDR5 memory on 2.4GHz configuration MacBook Air (13", 2011 model): 1.7GHz dual-core Intel Core i5 with 3MB shared L3 cache 4GB of 1333MHz DDR3 onboard memory Intel HD Graphics 3000 processor with 384MB of DDR3 SDRAM shared with main memory There's definitely a gap between them in terms of CPU speed and graphics, but what practical difference would this make on a day-to-day basis? On the one hand, I love the sleek, thin appearance of the Air. On the other hand, I don't want a machine that's going to be dog-slow when doing tasks such as running Virtual Machines, dual-booting to Windows and running multiple instances of Visual Studio, and maybe some light gaming. Is there going to be a major difference that makes the MacBook Pro a more attractive purchase?

• 59 vs 60 hertz on external display via DisplayPort

  - by Shiki

  Don't know if this is a really specific question or you'll help me out. Please do. I just bought a DeLock DisplayPort cable for my Lenovo T500. Tried to use it with the in-built Intel MHD4500, no use. With the ATI HD3650 (you can switch between the two vga on this machine) I get a normal picture, but only on 59hz. On 60 I get a smaller desktop size (strange). Any idea what can cause this? Will I have any problem if I use the 59hz? (Was using the display with a VGA cable but I get a blurry picture with that (dont matter what device I attach, VGA is like this on this display) and thats why I wanted to change.)

  Hi, I am new to the Web services scene. I currently have access to a RHEL5 box and i need to deploy a java web service on it. It runs apache and i know this because i have a website hosted on this machine. Now, i want to deploy a web service on to this website to be able to just pass a link to someone when they need to access my web service. Could someone point out a resource or explain what all i need to get the webservice deployed using Tomcat/Apache Axis and Java.
