• tmpfs changes size on restart

  - by ben

  I have a tmpfs mount defined in my /etc/fstab with a size of 1024m, but when I restart the server it sizes itself to 5.9G. If I run mount -o remount /dev/shm, the size will correct itself to 1G. But it'll revert the next time the server is restarted. The entry in fstab is: tmpfs /dev/shm tmpfs size=1024m 0 0 Could there another file that mount could be calling during startup? How might I find that file?

• Routing RFC1918 addresses through dd-wrt via a switch

  - by espenfjo

  I am a bit stuck with an experiment of mine. I have a network looking somewhat like this. | Internet | | ---- |Switch| ---- | | Server w/pub IP | DD-WRT router 192.168.1.1 | | RFC1918 clients 192.168.1.0/24 What I want is for the RFC1918 clients to speak directly with each others. On the server with the public IP I have this route: 192.168.1.0/24 dev eth0 scope link and can see that packets are infact reaching the dd-wrt router for 192.168.1.1, even though if I get no answer. Trying to reach one of the RFC1918 clients from the public IP server will get no result, as the dd-wrt router is not announcing that network on to its external interface (arp who-has 192.168.1.107 tell xxx.xxx.xxx.xxx, but no answer). The router being an WLAN dd-wrt router has of course a load of routes, VLANs and interfaces: xxx.xxx.xxx.1 dev vlan2 scope link 192.168.1.0/24 dev br0 proto kernel scope link src 192.168.1.1 192.168.1.0/24 dev eth1 proto kernel scope link src 192.168.1.244 84.215.64.0/18 dev vlan2 proto kernel scope link src xxx.xxx.xxx.xxx 169.254.0.0/16 dev br0 proto kernel scope link src 169.254.255.1 127.0.0.0/8 dev lo scope link 0.0.0.0 via xxx.xxx.xxx.1 dev vlan2 xxx.xxx.xxx.xxx being the public IP, and xxx.xxx.xxx.1 being the default route for the public IP. I am not sure where to continue with this. I would recon that I both need routing on the dd-wrt router, as well as some iptables magic? Why do something this complex? Why not ;) Also, do not mind that "Internet" can get RFC1918 traffic, it wont go outside of the walls. EDIT 1: Following the tip from stew I do indeed get the correct ARP flowing. And adding an iptables rule for allowing traffic from that specific public IPd machine I get traffic between the systems! Oddly enough though, the speed I get from Server w/pub IP - RFC1918 clients are the same as if the traffic were routed out onto the Internet and back. Edit 2: Ok, disconnecting the external Internet connection will still give the same, crappy transfer speed. So it has to be something else. Edit 3: Ok, I guess there are other reasons for this crappy speed. Case closed. :)

• Blocking ports on the public IP assigned to lo interface in GNU/Linux

  - by nixnotwin

  I have setup my Ubuntu server as a router and webserver by following the answer given here. My ISP facing interface eth0 has a private 172.16.x.x/30 ip and my lo interface has a public IP as mentioned in the answer to the question linked above. The setup is working well. The only snag I have experienced is that I could not find a way to block the ports exposed by the public IP on the lo interface. I tried doing iptables -A INPUT -i eth0 -j DROP, and my server lost connectivity to the public network (internet). I could not ping any public ips. What I want is a way to block ports that are exposed by the public ip on the lo interface. And also I require iptables rules that can expose ports like 80 or openvpn port to the public network.

• how to uninstall ubuntu 8 from ubuntu 10 dual boot

  - by umar

  I have ubuntu 8.04 and ubuntu 10.04 on my laptop, and i want to reclaim all the ubuntu 8 space so that i have just one operating system on my laptop. how can i do it? the output of sudo fdisk -l is as follows: sudo fdisk -l Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x31a431a3 Device Boot Start End Blocks Id System /dev/sda1 * 1 4959 39833136 83 Linux /dev/sda2 4960 5233 2200905 82 Linux swap / Solaris /dev/sda3 5234 12852 61192552 83 Linux /dev/sda4 12852 19458 53062657 5 Extended /dev/sda5 12852 19182 50847744 83 Linux /dev/sda6 19182 19458 2213888 82 Linux swap / Solaris i dont know which of sda1, ..., sda 6 etc ubuntu 8 is on. how can i find that out? The actual task is that i think a lot of space is devoted to ubuntu 8, if there is no easy way to get rid of it, then i want to repartition the disk so that about 50 GB of hard disk space is given to ubuntu 10's home folder from the ubuntu 8's home folder. but i hope that there is an easy way to get rid of ubuntu 8 alrogether and just have ubuntu 10 on my system.

• Sharing disk volumes across OpenVZ guests to reduce Package Management Overhead

  - by andyortlieb

  Is it feasible to create a single "master" OpenVZ guest who would only be used for package management, and use something like mount --bind on several other OpenVZ guests sort of trick them into using the environment installed by the master guest? The point of this would be so that users can maintain their own containers, and yet stay in sync with the master development environment, so they'll always have the latest & greatest requirements without worrying too much about system administration. If they need to install their own packages, could put them in /opt, or /usr/local (or set a path to their home directory)? To rephrase, I would like several (developer's, for example) OpenVZ guests whose /bin, /usr (and so on...) actually refer to the same disk location as that of a master OpenVZ guest who can be started up to install and update common packages for the environment to be shared by all of this group of OpenVZ guests. For what it's worth, we're running Debian 6. Edit: I have tried mounting (bind, and readonly) /bin, /lib, /sbin, /usr in this fashion and it refuses to start the containers stating that files are already mounted or otherwise in use: Starting container ... vzquota : (error) Quota on syscall for id 1102: Device or resource busy vzquota : (error) Possible reasons: vzquota : (error) - Container's root is already mounted vzquota : (error) - there are opened files inside Container's private area vzquota : (error) - your current working directory is inside Container's vzquota : (error) private area vzquota : (error) Currently used file(s): /var/lib/vz/private/1102/sbin /var/lib/vz/private/1102/usr /var/lib/vz/private/1102/lib /var/lib/vz/private/1102/bin vzquota on failed [3] If I unmount these four volumes, and start the guest, and then mount them after the guest has started, the guest never sees them mounted.

• How would you simplify this command?

  - by Andrei Serdeliuc

  I'm quite new to strace / netstat / etc. I'm using this command to get a trace of the apache process handling my request (telnet), is there a way to simplify it a bit? sudo strace -o /tmp/strace -f -s4096 -r -p $(netstat -antlp | \ grep $(lsof -p `pidof telnet` | grep TCP | \ perl -n -e'/localhost:(\d+)/ && print $1') | grep apache2 | \ perl -n -e'/ESTABLISHED (\d+)/ && print $1') Thanks!

• Can't get PHP Errors in IIS7.5

  - by Erling Thorkildsen

  I've tried the previously answered questions regarding this to no avail. Just installed PHP5 and IIS on my Windows 7 machine and I'm having trouble getting PHP Errors displayed instead of 500 Errors. In PHP; error_reporting = E_ALL display_errors = On In IIS I have htmlErrors set to Detailed which shows a detailed IIS 500 Error page. If set to Custom it shows a basic 500 Error page. If I set it to PassThrough I get a blank page (view-source reveals no code). My PHP log file is showing a Fatal PHP Runtime Error.

• Windows Server 2008 Terminal Server CALs and Remote Desktop

  - by Chalkey

  Recently we have have installed Windows Server 2008 R2 on one of our development boxes at work. We have 10 Client Access Licence's for Microsoft Windows Terminal Server 2008. I'm under the impression that these licences will entitle us to have 10 concurrent connections to Remote Desktop. At the moment we are only allowed two. Can we have a RD connection per CAL? If so - how do we configure this? Thanks!

• Opening firewall to incoming port 443

  - by jrdioko

  I recently set up the ufw firewall on a Linux machine so that outgoing connections are allowed, incoming connections are denied, and denied connections are logged. This seems to work fine for most cases, but I see many denied connections that are incoming on port 443 (many with IPs associated with Facebook). I can open that port to incoming connections, but first wanted to ask what these could be. Shouldn't HTTPS requests be initiated by me and be treated as outbound, not inbound connections? Is it typical to open incoming port 443 on consumer firewalls?

• Context menu opens slowly in Explorer in Windows 7, why?

  - by xxzoid

  I'm running a Windows 7 on my reasonably modern laptop, when I open the context menu in Windows Explorer it really takes it time to show up (~10 seconds). There are some programs that have their commands added to it (an archive manipulation utility, an antivirus, a version control system and such). I think one of them freezes the operation. Is there a benchmark tool to measure it somehow or a tool to turn them off by one in Explorer without uninstalling them (which would be a penultimate measure, because use them)?

• How to ensure local file is up-to-date or ahead (dropbox sync) before truecrypt auto-mount it?

  - by user620965

  There are a lot tutorials out there that states that dropbox build-in encryption is not secure enought. That tutorials recommands to sync a truecrypt container file to have all files in it securely encrypted. This setup is know to be limited. You can NOT have that truecrypt container file mounted on the same time on more than one location - if you have inserted changes to the contents of the container in more then one location at a time then this setup produces a conflict on the container file in the dropbox system - resulting in one container file for each location. In my case that issue is not relevant - i do not use my data on more than one location at a time. I want to use the auto-mount feature of truecrypt on startup of windows 7 to have a zero configuration environment - and start working right away. But i want to ensure that the local truecrypt container file is up-to-date before truecrypt mounts it automatically - imagine you updated the contents of the container on your primary location and your secondary location was off for a long time. In that case it can take "a long time" till dropbox sync is complete (e.g. depending on your internet connection and the size of the container file). There is a option in truecrypt that ensures that truecrypt do not update the timestamp of the container file - which speeds up the sync, because dropbox client is doing a differential sync then instead of a time consuming full-sync. That is an improvement to that setup, but this do not fix my issue. The question is how to make the auto-mount function wait for the container file to be up-to-date (updated by dropbox)? In contrast: if the file was changed local, but remote file (in the dropbox cloud system) is still old (not jet updated by the sync process / or process is progress), should not make truecrypt to wait for the sync. Suggestions?

• What is user/owner 24561?

  - by ralphthemagician

  So, I just installed the node.js package from nodejs.org and I was poking around to see what it installed. Over in /usr/local/bin I saw this owner 24561. I see it in a few other places too. What is this? What does it mean? Should it be root like everything else? lrwxr-xr-x 1 root wheel 66 Jun 23 13:02 mate -> /Applications/TextMate.app/Contents/SharedSupport/Support/bin/mate -rwxr-xr-x 1 24561 wheel 18865984 Jun 29 09:32 node -rwxr-xr-x 1 24561 wheel 355 Jun 29 09:32 node-waf lrwxr-xr-x 1 root wheel 38 Jul 3 12:15 npm -> ../lib/node_modules/npm/bin/npm-cli.js What was curious is that I couldn't find any other information about this user by Googling. Using OS X Lion 10.7.4 with Xcode installed if that makes any difference.

• New laptop battery: 80% capacity

  - by Danilo

  I have got an old laptop (HP Pavilion DV2000, 5.5 years old) and I just bought a new battery for it (10,8V 5200mAh 6 Cells) probably not an original one. When I charged it full the first time, it reached a capacity (as see through the Ubuntu 12.04 Power Statistics tool) of 80%. After 3 full cycles, it's at 79.5%. Do you think it is normal, or the battery may be damaged (and I can complain with the vendor)?

• Attempt to connect to wireless internet at home and i am asked for User Credentals, nothing I enter works

  - by lucig12

  I just got a new modem and am trying to connect my windows 7 desktop to the new wireless connection. I had no issues on the three previous connections I have used, but for some reason when I click on the icon for Wireless Network Connections, click on my network, it asks for User Credentials. Nothing I type in works. I have tried saving credentials in credentials manager, using my login info, using the network's login info, recreating the network manually, plugging and unplugging my modem, literally every solution on every forum for similar issues. I have no idea what to do now. any ideas?

• WD 1TB Passport Essential not working on some USB ports

  - by user143863

  I have a strange situation here. I got a new Toshiba P850/04P laptop, there are 4 USB 3.0 ports, 2 on the right and 2 on the left. When I plug my WD 1TB Passport Essential into the 2 ports on the left, the drive keeps disconnecting and then connecting again, on and off. Sometimes it works well for 1 hour and then disconnects and even shows the "please format your drive" message. What is odd is: this WD 1TB Passport Essential works perfectly on those 2 ports on the right side. It has been working fine on all other PCs and laptops. Another 500 GB WD passport can work with the USB ports on the left (the ones 1TB can not), also all other devices can work with all 4 ports. I am really confused! Does anyone know what the problem could be?

• Autosaving on emacs or xemacs files (preferably on loss of focus)

  - by Spencer

  Ideally I want to replicate with emacs functionality from TextMate, whereby on loss of focus i.e. I click away from the buffer, my file saves. If this isn't possible, I want to customize emacs so that it will autosave the file for every character I write. When I say this I don't mean I want to autosave to the ~ backup files. I want to save the file I am currently working on. I am working on a Fedora VM. Note I am not looking for a backup or autosave. I want the file I am actually in to save, so that if I loaded the html file I am editing in a web browser it would reflect my new changes without me having to explicitly change it.

• Laptop hangs on POST and does not finish except on rare occasions

  - by user1049697

  I have an old Toshiba Satellite A100 laptop that hangs on POST when I try to start it. On rare occasions it does finish the POST and boots Windows successfully, but most times it just finishes it partially and continues to hang. I can enter the BIOS though when it has frozen, but I have to open the DVD-drive first for some reason. The keyboard is not quite right either, and I can't navigate the BIOS properly because the arrow keys doesn't work. I tried an external keyboard, but the problem persisted. I have tried to remove the memory, hard drive, and battery to see if any of these were the problem, but it did not solve it. The one logical thing left to do would be to remove the CMOS battery, but the "brilliant" engineers at Toshiba have place it such that a complete disassembly of the machine is necessary. What this all boils down to is basically the question of whether I can "save" this machine and get it to boot properly, or if I should just send it off to recycling. I suspect it might need costly repairs, but I can't bring myself to throw it away before I have made sure it's completely dead.

• How to delete empty folders from a given directory in windows with a script

  - by Nicola Peluchetti

  I'm using r.js as a build tool but as of today that tools doesn't give me the ability to delete empty folders in the build dir. I've found these two scripts for /f "usebackq" %%d in ("dir /ad/b/s | sort /R") do rd "%%d" for /f "delims=" %%i in ('dir /s /b /ad ^| sort /r') do rd "%%i">NUL looking around the net but i always get %%i was unexpected at this time. or %%d was unexpected at this time. And i wouldn't know how to tell the script where my directory is. My build script is @echo off where /q r.js || ( echo requirejs node package is not installed. You must install node, npm and then run npm install -g requirejs goto :eof ) node r.js -o app.build.js :end I need to tell the script to remove all empty directories which are located inside ../../js

• How to set an executable white list?

  - by izabera

  Under Linux, is it possible to set a white-list of executables for a certain group of users? I need them to be unable to use, for example, make, gcc and executables on removable disks. How can this be done? Edit, let me explain better. I'm dealing with a high school IT system, young geeks that (during the lessons) want to play, surf the net, damage those computer however they can. The major step to achieve this goal was to remove the system they're familiar with and install Ubuntu in all the computers. This actually works quite well, but recent events proved that this is not enough. I want to allow them to execute certain safe programs, like Open Office, and to deny any other program, whether it is preinstalled software, something they carry in usb drives, a downloaded program or a script they program on site. It's possible to remove the 'x' permission on any file on the pc, but of course it would be impractical. Furthermore, they would be able to run anything they download. I thought the best solution would be to make a white-list of safe programs and to deny anything else, but I don't really know how to do it. Any idea is helpful.

  I am not sure if its my GPU / Memory or Hard drive thats failing. For example if I'm runnning more than one instance of chrome and running an application that takes up a lot of resources, my system will start to lag and freeze. When I launch Photoshop the GPU feature disables automatically, this also lags when I click on menus and when working on documents in Photoshop. I really dont know where to start, if i should buy a new graphics card or test the memory or could it be my OS drive?

• Pinned program on the taskbar is not grouping in Windows 7 Ultimate

  - by Magic

  Previously, I had pinned Google Chrome Dev to the taskbar. Being that it was unstable and crashed frequently, I decided to uninstall it. Before uninstalling, however, I did not un-pin its icon from the taskbar. Afterward, I installed Google Chrome Stable and launched it from the old pinned icon. This resulted in a new icon appearing in the taskbar. I figured this happened because the icon was originally for the Dev build, so I unpinned the icon and re-pinned Google Chrome. I launch Google Chrome again, but I still get a new icon! Re-pinning the icon should have fixed it, no? Why aren't my Google Chrome windows grouping together?

• Google Chrome pinned to Windows 7 taskbar not opening under pinned icon

  - by Slothsberry

  I have both Google Chrome and Eclipse pinned to my taskbar in Windows 7 64-Bit. However, when I launch these programs, they don't appear to open under the pinned taskbar icon Eclipse behaves similarly. The Eclipse launcher/workspace selector is under the pinned icon, but once the IDE opens, it moves from the pinned icon, to a new group at the end of the taskbar. Unpinning/repinning doesn't seem to do the trick. It's bothersome to have taskbar space wasted on both the launcher icon, and the window button. Anybody have an idea how to get normal behavior out of the taskbar?
