• Ubuntu apt-get install (--download-only) executed from another machine on behalf of mine

  - by Maroloccio

  I have a server on a network segment with no direct or indirect access to the Internet. I want to perform an: apt-get install <package_name> Is there a way to somehow delegate the process of downloading the required files to another machine by exporting the server configuration so as to satisfy all dependencies while running: apt-get install --download-only <package_name> Can, in effect, apt-get install read a configuration from an exported archive rather than from the local package database? Can the list of packages to be downloaded be retrieved, along with an installation script to perform the installation, instead of the actual packages? (a further level of indirection which would help me schedule this with wget at appropriate times...)

• Verizon Fivespot firewall

  - by Patrick

  I have a Verizon Fivespot Wi-Fi router and am having issues connecting to the computer that uses it to get on the internet. I am able to connect to the Fivespot admin pages remotely and I am able to connect to the internet from the computer behind the Fivespot. There are two sections pertinent to this issue, Port Filtering And, Port Forwarding I've tried each individually and both together but cannot access anything through the router except for the admin page. I am trying to connect through SSH to an Ubuntu 10.04 box over wifi. I have called Verizon Tech Support but they were unhelpful, the person essentially read what it says on each screen without any elaboration. Any help is greatly appreciated!

• How do I create ruled lines in Word 2007?

  - by tobeannounced

  My aim is to set up Word to use the 'Cornell Notetaking method', and I would like to be able to have 'ruled lines' as part of my page in word. Currently, I have a split textbox, however obviously this does not allow the text to flow between lines. The underlining method does not work well enough, and I had read something about a college ruled template, however I was not able to find that. So is there any solution at all - by either creating lines in the textbox, or making the text flow between textbox rows?

• Homedir inside homedir restricted access

  - by blid

  On my VPS i've installed debian, apache+php. I have 2 users: foo and bar. Apache is configured to execute php files from /home/foo/htdocs. I created dir: /home/foo/htdocs/bar/ and made it home dir for user bar. Hover, I need to make a restriction: bar can't read, write or executre any files outside his own dir, but Apache has to be able execute all php files from /htdocs. I tried to chown the bar dir only for user bar, also experimented a lot with chmod but without a result so far. If there's any better way to satisfy my needs don't hesitate to write about it. Thanks in advance

• Adobe software does not save to network share

  - by Bart van Heukelom

  I'm running Windows 7 inside virtualbox on a linux host. I have shared my linux filesystem so it's accesible in Windows under \vboxsvr\sharename. I've mounted this share on S:. For most software, it works fine. Adobe software like Photoshop has problems with it though. I can read from S: just fine, but if I try to save something it gives me the message "There are no more files". How can I make it able to write to the share?

• Free / Cached / Available memory on Linux

  - by pkoraca

  I have read that linux uses free memory for caching, to make system faster. However, both Nagios and Paessler PRTG monitoring system show me that my memory usage is critical. I could change Nagios mem_usage script to sum free and cached memory, but would that be correct information? I doubt that they misunderstood Linux memory usage. Lets say I have 8 GB RAM. 5 GB are used, 2 GB is cached, and I have 1 GB of free memory. Real available memory should be free+cached (3 GB)? If some new application would need additional 3 GB RAM, could it take everything from cache and free without using swap, or is there a minimum that should be in cache? Real example: $ cat /proc/meminfo MemTotal: 5984256 kB MemFree: 137052 kB Buffers: 140484 kB Cached: 3439616 kB SwapCached: 244 kB Active: 3148824 kB Inactive: 2341768 kB ... My monitoring tools show that I have 137 MB free RAM, however I have ~3,5 GB in Cache. Thanks!

• PHP Runs Very Slow on IIS7. Need Help optimizing our config

  - by Kendor

  Am running a PHP based web app on our Windows 2008 cloud-based server. The app, which runs fine outside of our environment (e.g. a different IIS server), but is VERY slow in our environment. Based on googling this is a relatively common situation. I installed PHP and MySQL via the IIS web deployment method... Here's our setup: Windows 2008 Server Enterprise SP2 (32-bit) Microsoft-IIS/7.0 MySQL client version: mysqlnd 5.0.8-dev - 20102224 $Revision: 321634 $ PHP extension: mysqli Update for IIS 7.0 FastCGI Windows Cache Extension 1.1 for PHP 5.3 I had read elsewhere that ipv6 might be an issue, so I turned this off on the network adapter. The app is using: localhost as its connection Be easy on me, as I'm a bit green about some of these components... Also, rewriting the PHP app or modifying it is NOT an option. I'm reasonably SURE that our config is the issue.

• 2010 MBP HD speed sanity check?

  - by hvgotcodes

  I have a 2010 MBP with the 7200 rpm hard drive. I was copying a 2.1GB file, and noticed read/write speeds of around 20MB/s. Is that reasonable? Seems slow to me.... What is the proper way to benchmark a HD on OS X? Googling I see xbench, but that hasn't been updated in years. I also see some guides for using the command line. The goal would be to benchmark my drive and then compare the results to some official scores that the drive should be getting.

• Restrict Applications access to Device

  - by Dboy1612

  I have a PC that has the ability to handle running multiple game clients at once (specifically Tera Online). What I'd like to do is assign and/or restrict each clients access to a device (Gamepad) so that the actions from each device only effects the client I specify. After doing some research with Python's PyGame, I can see that a Gamepad essentially works like a Keyboard does by sending global key events to the entire system, and then the application reading those events. Question is, how can I make it not global? ONly have one application read one controller? Any help is appreciated!

• Our company claims that the DLP system can even monitor the contents of HTTPS traffic, how is this possible?

  - by Ryan

  There is software installed on all client machines for DLP (Data Loss Prevention) and HIPAA compliance. Supposedly it can read HTTPS data clearly. I always thought that between the browser and the server, this was encrypted entirely. How can software sneak in and grab this data from the browser prior to it is encrypted or after it is decrypted? I am just curious as to how this could be possible. I would think that a browser wouldn't be considered very secure if this was possible.

• How can I set up an FTP user with a home directory inside another user's home folder?

  - by simon180

  Hi I have an Ubuntu (Hardy) server which I am using to host multiple websites. All of the sites are stored in subfolders of a public_html folder for my main login to the server and accessed via a single SSH account. I now have a website user who wants FTP (or similar) access to enable them to upload various files etc to the directory where their website is situated, however I still need the SSH account to have access to this directory as I may need to make changes using my master account. Basically I want to create an FTP account (I have VSFTPD installed) for a user with the home directory inside my own user account but they should only be able to read/write to this folder or its subfolders but not go further up the directory tree. How can I achieve this? Thanks

• Is there a free, lightweight iTunes replacement for Windows?

  - by elsni

  Related: Is there an alternative to iTunes? (for Windows or Mac) thats free? I'm looking for a free, lightweight iTunes replacement for my Windows XP Netbook. iTunes itself is slow and bloated. The software should be able to read the iTunes library, espeacially the ratings of the songs and the intelligent playlists. I don't need the sync to an iPod because I don't own one, I used iTunes only as a jukebox. I also don't need the store, the podcasts and all the other things iTunes provides. Does someone know a good alternative?

• file copy error from system to cifs mount

  - by dwpriest

  When coping a file greater than 64kB from an Ubuntu server to a CIFS mounted windows share, most of the data is copied, but it seems the last chunk doesn't get copied. The size doesn't match, and the md5 check sums don't match. I have plenty of file space, but then I use cp, I get the following... cp: closing `cloudBackup/asdf.txt': No space left on device Using rsync, I get the following... rsync: close failed on "/home/fluffy/cloudBackup/.asdf.txt.qrBWe6": No space left on device (28) rsync error: error in file IO (code 11) at receiver.c(752) [receiver=3.0.8] rsync: connection unexpectedly closed (29 bytes received so far) [sender] rsync error: error in rsync protocol data stream (code 12) at io.c(601) [sender=3.0.8] I have full read/write permissions on the mounted share. I can copy via SSH just fine. Any ideas? Thank you

• Unidentified network: How to configure TCP/IPv4 for Win7?

  - by Zolomon

  When I try to connect to internet I keep getting the error "Unidentified network". I've tried numerous attempts at restoring access without success. IP release, flushing DNS cache, reinstalling NIC, reactivating NIC, resetting router and so on... I've read several times that it's my default gateway that's wrong. Currently I've had automatic IP/DNS configuration set without any problems, and then it stopped working for some reason. Anyone know how I specify the IP? My subnetmask is 255.255.255.0, default gateway is 192.168.0.1 but I have no idea how to determine what IP I should set. I use a D-Link DIR-655 and other computers on the network have IPs like 192.168.0.194, next is 192.168.0.197. (I'm completely lost and am trying to cool down after two weekends of debugging filled with despair.)

• Which is the best way to sync and share contacts and calender between Thunderbird, iPhone and Android?

  - by bensch

  I would like to keep my contacts and a calendar synchronized between several desktops and cellphones. Is there a way to achieve this without using Google or similar organisations? I want to keep my data protected and safe, so an encrypted transfer would be useful. Do i need to install a service on my own rootserver? or are there any services available, that are safe? I read this post, but there is not mentioned not to use Google: Thunderbird contacts sync so no solutions with SoGo or LDAP. maybe Zimbra is a solution? or Funambol? I tried kolab, but had some unsolveable problems.

• Does my dd-wrt installation support firewall logging?

  - by SpikeX

  I would like to log firewall events. I know this is possible with dd-wrt, but a lot of the documentation I've read states that this isn't possible with a micro installation of dd-wrt (based on BusyBox). I have a Netgear WNDR3700v2 router, and it does have BusyBox installed on it, but I don't know if the dd-wrt build is a micro build or not. How can I find this out, or how can I find out if my router supports firewall logging or not? Currently, if I enable all firewall logging (setting everything to "Enabled" and/or "High" gives me back blank firewall logs - but syslogd is working because I can view other system log messages).

• dd cloned win2003 std ntfs partition, "no operating system found".

  - by 3molo

  I cloned an existing ntfs partition on faulty hardware using dd and gzip. The copied partition was then written to a newly created ntfs partition on a new disk (on another server) and the bootable flag was set. However, the "Operating system not found" (or is it No operating system found?) is what happens when I try to boot it.The faulty server is part of the AD domain, but I do not have the local administrator password, so I couldn't use the repair console of windows 2003 to fixmbr. I did try to do a normal repair during win2003 installation menu, but with no success. Both windows installation and Linux recognizes it as a ntfs partition of its true size, and files can be seen and read. I've done this a couple of times before, but I didn't encounter this problem. Of course I encountered other problems, like BSDO due to lack of hw drivers etc - but that was pretty easily fixed. Why am I failing to get the copied partition to even be recognized as a bootable disk on the new server?

• Cygwin file and directory user and group

  - by dvanaria

  I use Cygwin as my main development environment on both my home and work computers. In order to share files between the two computers, I use Dropbox, which is installed in the following folder on both computers: c:\cygwin\home\dvanaria\dropbox Everything works great, except for one thing. When I'm working on my home computer and do an ls -l on any directory, all the files show up as owned by dvanaria of group Users. But when I work from my work computer, an ls -l shows all files as being owned by Administrators and of group Domain Users. I know Cygwin uses some kind of mapping between Windows users and permissions to the /etc/passwd file. But to be honest I have no idea how this file works or how it maps to Windows under Cygwin. Could anyone help figure this out? The main problem is that I can't edit any files when using my work computer, only read them.

• Is there a MySQL performance benchmark to measure the impact of utf8_unicode_ci versus utf8_general_ci?

  - by MiniQuark

  I read here and there that using the utf8_unicode_ci collation ensures a better treatment of unicode text (for example, it knowns how to expand characters such as 'œ' into 'oe' for searching and ordering) compared to the default utf8_general_ci which basically just strips diacritics. Unfortunately, both sources indicate that utf8_unicode_ci is slightly slower than utf8_general_ci. So my question is: what does "slightly slower" mean? Has anyone run benchmarks? Are we talking about a -0.01% performance impact or rather something like -25%? Thanks for your help.

• Unable to use cloned VM, OpenSUSE, VirtualBox

• Auto-scaling EC2 Servers and Updating Code

  - by jstats

  We've come to the point where we need to set up autoscaling for our web server and I'm unsure how to go about the process of scaling servers and updating the the existing code without remaking a new AMI and changing the autoscale config to use it. I've read a bit about people bundling the new code and uploading it to s3 and having new servers grab the bundle on boot up but that doesn't seem all that pleasant either. Currently the web app's files live in a git repo, and when we update the code, we push it to github, ssh into the web app and run a hook to bring down the latest code. So I was thinking that another option could be to just run that hook on an hourly or daily cron task. Unfortunately that doesn't cover everything type of update (for example new blog posts' images and such which aren't included in the git repo) but it's something. Could anyone provide some advice on what a common solution is or anything as to why my proposed solution is a bad idea? Thanks all

• Set Up Port-Forwarding on Netgear N300 Router

  - by Smitty

  I have a Netgear N300 router that has DynDNS.org as a preset DDNS option. After setting it up it (unsurprisingly) sent traffic directly to my router. I'm essentially using this to connect remotely to my home (virtual) machine/s. From what I've read, it seems like I need to set up port forwarding. I tried forwarding "all" inbound traffic to a specific IP but that just didn't work. What am I doing wrong? Also, I just noticed I get this error after applying the settings: "The specified port(s) are being used by other configurations. Please check your configurations of Remote Management, Port forwarding, Port Triggering, UPnP Port Mapping table, RIP, and Internet connection type"

• how to protect from editing or converting to text a pdf file?

  - by Layla

  I am using a version of Ms Office of 2010, it was a beta version of public domain (I dont recall the name, but I believe it was called Blue version or something like that). I usually make my documents using the MS Word and then saving it like a pdf file using the function to publish as a pdf file within Word. The problem that I have is that some people are converting my documents into text, putting their name on it, and credited my work to them; so I would like to know if there is a way to: protect with a password the editing of my document protect it from converting into txt, with a password if its possible maybe but a digital signature in which it says my name as an author I want that the people who access it can only read it, and nothing more. I am using MS Word 2010 and Foxit Pdf (an old version), I usually do not use Adobe Acrobat. Thanks

• after power outage, monitor won't turn on

  - by J82

  I had a power outage in my apartment today during a Windows 7 SP1 update. I installed SP1 and it told me to restart so I did and that's when the power outage happened. After the power came back on, I started the computer and it looks like the computer is running normally but my monitor is not getting a signal. I am using a Wacom Cintiq 21UX. I tried unplugging all the cords and plugs in the power strip and turning it back on. I also tried a strange method I read in another thread of removing the power cord, holding the on button for 30 seconds, putting the power cord back in, and turning it on. Still no dice. How can I get my monitor to turn on? please help..
