• Missing characters when printing in linux

  - by jarvisschultz

  I have a pdf that I was printing recently, and on the final printout there is a single character that doesn't print. It is the greek letter phi, and the pdf was built with pdflatex. The phi shows up in every pdf reader I have tried, and if I convert to a ps using pdftops before printing that solves the problem. Also, I sent the pdf to a buddy who has a very similar machine (Ubuntu 12.04 64 bit, with the same printer drivers), and he was able to print it (to the same printer) and the character showed up. Clearly I have a workaround, but I'm more curious as to where I should be looking to figure out what is causing this bug? What is the printing "toolchain", and where could it be going wrong?

• Please help to troubleshoot the issue with Inspiron 8600 laptop

  - by user34300

  Hello! I have a Dell Inspiron 8600 laptop which display stopped working all of the sudden. It started to show a purple fog pattern along with some color vertical lines. I talked to Dell support and they told me that is a screen gone bad and I should get a new one which I did. But surprisingly the new display won't work either! The pattern on the screen is different but still no picture. So I tried to connect the old display to another laptop (Lenovo Z61) and it turns out it works just fine with it! So please help me to identify the cause of the issue. I think it could be a video card but the external display works flawlessly. I appreciate your thoughts about it so I won't need to buy spares which I don't need. Thank you! P.S. Please do not suggest to contact Dell support again.

• Installing MoinMoin -wiki to my user directory on a server with no root access

  - by deiga

  Hello all, I posted this on webapps, but they told me to come here :) I've been trying to install MoinMoin -wiki on this webserver, where I have no root access. The server doesn't support wsgi, but it does support cgi/fcgi/etc. I've scoured google for a simple guide on how to accomplish this, but the only guides I found were from the year 2004 or so. Other guides always assumed that one has root access. So can anyone link a good tutorial for my question or just help me out here? Your help is appreciated :) P.S. Sorry if this is the wrong stack -page

• PHP won't run on Fedora 15

  - by George

  I have followed this exact tutorial on installing php on a Fedora 15 system. I have all the necessary packages installed with no errors. Yet the simple phpinfo() test page will show - it will show a blank page. When I try to see the source, I see it downloaded my .php file as plain text and loaded it in the browser. So I am guessing for some reason php module is not loaded in httpd. Does anyone have any idea why? P.S. I am really hoping SELinux this time has nothing to do with this!

• Apache .htaccess problem: No input file specified.

  - by Michal M

  Hello Everyone, Can someone help me with this. I'm feeling like I've been hitting my head against a wall for over 2 hrs now. I've got Apache 2.2.8 + PHP 5.2.6 installed on my machine and the .htacces with code below works fine, no errors. RewriteEngine on RewriteCond $1 !^(index\.php|css|gfx|js|swf|robots\.txt|favicon\.ico) RewriteRule ^(.*)$ /index.php/$1 [L] The same code on my hosting provider server gives me a 404 error code and outputs only: No input file specified. index.php IS there. I know they have Apache installed (cannot find version info anywhere) and they're running PHP v5.2.8. I'm on windows xp 64-bit, they're running some Linux and php in cgi/fastcgi mode. Can anyone suggest what could be the problem? PS. if that's important that's for CodeIgniter to work with friendly URLs.

The following is my configuration for mod_proxy: ProxyRequests Off ProxyPreserveHost On <Location / ProxyPass http://localhost:3000/ ProxyPassReverse http://localhost:3000/ Order deny,allow Allow from all </Location Mongrel/Rails ist running just fine, because I can access it from my browser, and even with lynx on the server.

• Creating a folder named after the current date and time

  - by lowerkey

  I'm trying to create a powershell script that creates a new folder with the current date (formatted as yyyy-MM-dd) as a name. Here's what I have so far: PS C:\Users\me\Desktop> powershell.exe -command "new-item ($(get-location) + (Get-Date).year + "-" + (Get-Date).month + "-" + (Get-Date).day) -type directo ry" Die Benennung "C:\Users\me\Desktop" wurde nicht als Name eines Cmdlet, ein er Funktion, einer Skriptdatei oder eines ausführbaren Programms erkannt.

• How to stop nginx on Mac OS X

  - by Alex Kaushovik

  I've installed nginx server on my Mac from MacPorts: sudo port install nginx. Then I followed the recommendation from the port installation console and created the launchd startup item for nginx, then started the server. It works fine (after I renamed nginx.conf.example to nginx.conf and renamed mime.types.example to mime.types), but I couldn't stop it... I tried sudo nginx -s stop - this doesn't stop the server, I can still see "Welcome to nginx!" page in my browser on http://localhost/, also I still see master and worker processes of nginx with ps -e | grep nginx. What is the best way to start/stop nginx on Mac? BTW, I've added "daemon off;" into nginx.conf - as recommended by various resources. Thank you.

• A good log file analyzer for windows

  - by Raminder

  Is there a text-editor for windows that can open for me first n lines of a large file? It would be nice if it could also open a set of lines from the middle of the file. EDIT: Basically my requirement is that I want to analyze huge(2GB) log files. So any good tool that can open huge files with some analysis capabilities(searching, text highlighting etc.) would be nice. I like notepad++ but it wouldn't open a file even of about 650 MB. P.S. - Open source tools will be preferred.

• knife azure image list doesn't return User image

  - by TooLSHeD

  I'm trying to create and bootstrap a Windows VM in Azure using knife-azure. I initially tried using a Public Win 2008 r2 image, but quickly found out that winrm needs to be configured before this can work. So, I created a VM from that image, configured winrm as per these instructions and captured the VM. The problem is that the image does not show up when executing knife azure image list. When I try creating the server with the image name from the Azure portal, it complains that it does not exist. I'm running Ubuntu, so I tried the Azure cli tools and it doesn't show there either. I installed Azure PS in a Win 8 VM and then it shows up. Feeling encouraged, I installed Chef and knife-azure in the Win 8 VM, but it doesn't show up there either. How do I get my User image to show in knife azure?

• Why has my Mac been running fsck_hfs for two days now?

  - by Nate

  I first noticed that fsck_hfs was running, taking up 50-75% of a CPU, yesterday. It continues to run today. ps shows that it is doing /sbin/fsck_hfs -f -n -x -E /dev/disk3. Only problem: I don’t think I have a /dev/disk3. Why is it running? Will it ever finish? Can I kill it? What is /dev/disk3? Could it be my Time Machine volume, which is not mounted at the moment? System Info: MacBook Pro (2008). It has two disks installed—the internal disk (/dev/disk1) and a PC Card SSD (/dev/disk0, surprisingly). It connects to a remote Time Machine volume attached to an Airport Extreme base station.

• Tunneling HTTPS traffic via a PUTTY/SSL tunnel with SOCKS

  - by ripper234

  I have configured a SOCKS ssh tunnel to a remote proxy, and set my Firefox to use localhost:<port> as a SOCKS proxy. My intention is to tunnel outgoing HTTP/S connections from my machine via a specific 3rd party server I own (on AWS). In my testing, HTTP UTLs are forwarded properly (e.g. when I access http://jsonip.com/ from my computer I do get the server's IP) However, whenever I try to reach an HTTPS address, I get this error: The proxy server is refusing connections How do I debug/fix it? My PUTTY tunnel config is simply (some random source port number + dynamic checked): P.S. I'm aware I might need to manually accept SSL certificates. The reason I'm doing this is to resolve problems using gmail as an outbound SMTP service.

• something like persistent X forwarding?

  - by Arthur Ulfeldt

  I'm having trouble with the title on this one, please edit. When users connect to a VM with VNC/NX/RDP/other-tla they get a persistent desktop in a window . When they connect using ssh -X forwarding they get a local window managed by the local windo-manager that is not persistent. 1: is there a way to run a program on the VM and have it managed locally AND have it persistent? 2: can the client be on windows or OS-X? ps: in this case the vm's are running Ubuntu

• rsnapshot intervals in configuration file...

  - by Patrick

  A simple question about rsnapshot. In order to perform daily backups I'm going to add lines to cron in my Ubuntu. Then, why do I have also these lines in the rsnapshot.conf ? ######################################### # BACKUP INTERVALS # # Must be unique and in ascending order # # i.e. hourly, daily, weekly, etc. # ######################################### interval hourly 6 interval daily 7 interval weekly 4 #interval monthly 3 If I use cron, should I disable them ? thanks ps. I've just realized that in the crontab I still have "hourly" and "daily". Should I then uncomment only the one I use in the crontab ? And what's the point to specify hourly if it is already specified in cron ? I'm a bit confused. # crontab -e 0 */4 * * * /usr/local/bin/rsnapshot hourly 30 23 * * * /usr/local/bin/rsnapshot daily

• How does Apache handle port forwarding?

  - by vfclists

  I setup a localhost portforwarding configuration in the coLinux .conf file, forwarding port 8090 to port 80 in the VM. When http://localhost:8090 is entered in the browser, I get the correct response from nginx, but with Apache the response get the error /htdocs not found in the log. However if I do a local port forwarding from 8090 to port 80 via SSH Apache responds fine. Is there something about the way Apache handles the port redirection that causes it to fail? PS, For those unfamiliar with coLinux it allows localhost connections to get to the VM by forwarding localhost ports on the Windows host to ports on the VM, as the 10.x.x.x IP it not accessible from the Windows host.

• Hyper-V CPU Utilization, Good Tools?

  - by yzorg

  I just learned a ton from this post: Host CPU% doesn't include child VM CPU%, specifically I learned that both the 'host OS' and 'child VM' are siblings within the HyperVisor layer. Are there good utilities for 'watching' the total CPU and other resource counters at the HyperVisor (hardware) layer? I know perfmon (watching special Hyper-V CPU counters) is the standard answer, but I've stayed away from perfmon for ad-hoc monitoring. Is there a good OSS or free tools to 'watch' the resource utilization as I create multiple new VMs running on the server? I'm a developer, so if there aren't any good UI tools to surface this data I'd consider creating one, but only if needed. P.S. My specific scenario is I'm creating new web, SQL and back-end server VMs for new Windows 8 Server and SQL 2012 (entire application stack). I need to monitor them for utilization and know when I need to grow beyond 1 host (I'll need to split the VMs into separate hosts as I hit hardware limits of the 1st host, and diagnose problems).

• How to setup a fast VPN server

  - by Saif Bechan

  I am trying to set up a VPN that has a fast download speed. The server I have is a linux server and from there I can download 2 megabytes a second. At home I can also download with 2 megabytes a second. All the downloads I do are from the same source, no different server. Now I have set up a VPN connection between my home and the server, and now I am only downloading 64 kilobytes a second! The connection I have created is a PPTP server on a debian machine. Now my question is if it is possible to optimize this connection. Should I maybe switch to OpenVPN, or change operating systems? Or are there some kind of settings to tweak to make the connection optimal. PS. The server I am running is on a XEN node. I have done the proper ip forwarding.
