• Win 2008 Server configuration

  - by user123790

  Let me preface my question by saying I'm a novice in regards to server configuration. It's been 12+ years since I've attempted this. What we (our small office) are trying to achieve is to setup a Win 2008 server (located in a home) in a home network configuration (basic wireless router w/DHCP) that we (the office) can VPN to from our office. I have installed the software, installed DHCP, removed DHCP from the router, set the scope for 100 IPs and am now looking for information as to where I go from here? I believe I need to configure DNS and possibly set up static routes on the router for the home devices that need internet? The wireless clients are not receiving IPs is the current issue that I'd like to tackle. Also, would it be feasible to use the router's DHCP to assign IPs rather than having the server do it? If so, what would be the most direct way to accomplish this? I appreciate any help in this matter. Thanks

• Developing with Oracle ADF Mobile and ADF Business Components Backend

  - by Shay Shmeltzer

  It's great to finally have the Oracle ADF Mobile solution out there. If you are not familiar with ADF Mobile - it basically lets you build applications that run on iOS and Android devices using the concepts you already know - components based UI constructions (same idea as JSF), taskflows, data controls, Java and of course JDeveloper. I created one demo that shows how to build an on-device application that gets data from local Java files (that run on the device - yes we do Java on iOS too) - you can see it here. However, one thing many of you might be wondering is how can you get data from your database into these mobile applications. Well if you already built your data access with Oracle ADF Business Components then here is a two step video demo that shows you what to do. The steps are: 1. Expose ADF Business Components as Services 2. Create an ADF Mobile application that consumes the above services with the Web service data control Simple right? That's the whole point of ADF Mobile - making on device application development as simple as possible. Try it out on your device.

• Location Directive in a VirtualHost

  - by Yehia A.Salam

  I'm trying to add server-status location directive under one of my virtual host, however i'm getting a 403 Access Forbidden when browsing to www.mywebsite.com/server-status. Is it legal to put the Location Directive under a virtual host?

• Ubuntu hangs on boot when NFS-mounting entries in /etc/fstab, but they mount cleanly otherwise

  - by lorin

  I'm managing several Ubuntu 9.10 servers that NFS mount several folders (including /home). I'd like these folders to be mounted at boot time. I would like to have several entries in my /etc/fstab to accomplish this, e.g. 192.168.1.100:/home /home nfs rw 0 0 192.168.1.100:/usr/ansys_inc /ansys_inc nfs ro 0 0 Unfortunately, with this configuration, the servers usually (although not always) hang during the bootup sequence when trying to do the NFS mount. if I comment out these fstab entries, reboot the machine, uncomment them and mount them manually using the shell, the folders mount cleanly. I'm not sure how to go about debugging this problem. It seems like it has something to do with the boot sequence, that some relevant process hasn't been started by the time the OS tries to mount the folders.

• Network router and switch configuration

  - by gilly3

  Can I put a switch before my router in my home network? Here is a diagram of how I want to set up my network: ________________________________ ________________________________________ | | | | | Cable Access Panel | | Home Office | | _____________ ________ | | _____________ | | | | | | | | | | _________ | | | Cable Modem |--->| Switch |-------------->| Router |____| | | | |_____________| |________| | | |_____________| | Printer | | |______________________/____\____| | / | \ |_________| | ___/_ _\___ | _____/ ____|____ \_____ | | | | | | | | | | | | | | PC1 | | PC2 | | | PC3 | | Ext. HD | | PC4 | | |_____| |_____| | |_____| |_________| |_____| | |________________________________________| The reason I want to do this is because my router is also my wireless access point. My cable modem is located in the far corner of my home where my phone/tv/network access panel is. I'd rather keep the wireless access point in a more central location, but I'm not sure if DHCP will continue to work properly with that configuration. Edit: I'd like to continue to be able to share files and access my networked drive and printer from each computer in the house.

• Sharing accounts between multiple computers running Ubuntu Linux

  - by john

  My school has a computer lab full of machines running Red Hat Linux. They have it set up so that you can log into any computer in the lab, and it automatically loads your desktop, home directory, etc, which makes it so all computers in the lab look the same to you, regardless or which one you're using. I have two computer at home running Ubuntu Linux. Could I do this same thing with my computers at home? What's it called, and how do I find documentation on how to set it up? Thanks!

• Software for defining rules for folder permissions and monitoring deviations

  - by Kjensen

  Let's say a company has a large number of users, and each user has a home area. On each share used for home area folders, I would like to define some rules saying who is supposed to have which permissions on the folder. Then I would like to audit automatically, that this is actually the case and get some sort of report on deviations. So a rule for \MegaServer\Home01 could be defined something like: Domain Admins - Full Control Backup Agent - Read [Home folder owner] - Full Control I am talking about Windows platform and Windows servers, although I think it would most likely also work for *nix machines that expose Windows shares. Does software like this exist? I could roll my own basic version, but if something already exists, that is usually a better option. I am aware of tools to make displaying permissions easier (AccessEnum, DumpSec), but that is not what I am looking for.

• Apache Request IP Based Security

  - by connec

  I run an Apache server on my home system that I've made available over the internet as I'm not always at my home system. Naturally I don't want all my home server files public, so until now I've simply had: Order allow, deny Deny from all Allow from 127.0.0.1 in my core configuration and just Allow from all in the htaccess of any directories I wanted publicly viewable. However I've decided a better system would be to centralise all the access control and just require authentication (HTTP basic) for requests not to 127.0.0.1/localhost. Is this achievable with Apache/modules? If so how would I go about it? Cheers.

• Why is the "file" command get confused on .py files?

  - by pythonic metaphor

  I have several python modules that I've written. Randomly, I used file on this directory, and I was really surprised by what I saw. Here's the resulting count of what it thought the files were: 1 ASCII Java program text, with very long lines 1 a /bin/env python script text executable 1 a python script text executable 2 ASCII C++ program text 4 ASCII English text 18 ASCII Java program text That's strange! Any idea what's going on or why it seems to think python modules are very often java files? I'm using CentOS 5.2.

• 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.

• Moving to New Machine... also upgrade to 64bit. What steps?

  - by Kendor

  I am about to move to a new Lenovo X201 from current X61. Current setup has separate \home, separate swap file, also separate \Data partition. Am currently running 10.04 32 bit. Am considering running 64 bit on new machine because I will now have 8 GB of RAM. And would like to also move to 10.10. Ideally I would like preserve as much of my current setup as possible... New machine has Win7 on it, but will blow that away, as I've made a clonezilla copy of it, and will use VirtualBox for when I need Windows. Can someone suggest a good step by step for me? I'm networked to a NAS and also have plenty of external USB storage in case I need intermediary steps. So do I set up new machine first with 64bit 10.10, with partition scheme I want? then rsnyc over \home from old machine (over write target home)? Do I need to upgrade the X61 first to 10.10?

• Why is my nginx alias not working?

  - by Rob

  I'm trying to set up an alias so when someone accesses /phpmyadmin/, nginx will pull it from /home/phpmyadmin/ rather than from the usual document root. However, everytime I pull up the URL, it gives me a 404 on all items not pulled through fastcgi. fastcgi seems to be working fine, whereas the rest is not. strace is telling me it's trying to pull everything else from the usual document root, yet I can't figure out why. Can anyone provide some insight? Here is the relevant part of my config: location ~ ^/phpmyadmin/(.+\.php)$ { include fcgi.conf; fastcgi_index index.php; fastcgi_pass unix:/tmp/php-cgi.sock; fastcgi_param SCRIPT_FILENAME /home$fastcgi_script_name; } location /phpmyadmin { alias /home/phpmyadmin/; }

• suddenly cannot mount nfs share from windows 7

  - by bing

  I recently reinstalled my file server (moved from fedora to ubuntu server). Now I cannot mount my nfs share from windows 7, mounting from mac osx works fine. In windows I either keep getting "the semaphore timeout period has expired" or "an unexpected error has occured". Does ubuntu need some special magic to allow windows 7 to mount an nfs share? This is my exports file /home/bing/ 192.168.1.*(rw,async,insecure,no_subtree_check) /home/bing/mnt/EXTRN2 192.168.1.*(rw,async,insecure,no_subtree_check) /home/bing/mnt/EXTRN3 192.168.1.*(rw,async,insecure,no_subtree_check)

• Mount remote drive by port forwarding

  - by Anushka

  I have a windows 7 computer at home and a remote windows XP machine with an external USB drive attached to it. I would like to be able to copy files to and from home/the remote USB drive. The problem is that the only way of contacting the work computer is by first sshing into a different remote linux machine as there is a firewall that prevents direct internet connection. I can see two possible solutions but I don't know how to do them. Set up winscp using ssh port forwarding via the linux box so that I can copy to and from the two windows machines. I assume that I would need to run an ssh server on the XP machine as well to do this? Mounting the remote USB drive on the remote windows machine from the home XP machine via ssh port forwarding again via the linux box. Does anyone know how to do either solution?

• Remote Desktop connection breaks the wireless connection

  - by Michal Talaga

  When I connect to my Windows 8 Professional machine via Remote Desktop (RDP) I almost always get my WiFi connection broken. The setup: T61P Lenovo Laptop + W8 at home Wireless Router with NAT forwards connections to that machine Windows 7 laptop at work connecting to the home laptop When I connect, very often I get to login and suddenly connection is lost and I cannot reconnect again. When I get home I find my WiFi connection is still connected to the Access Point but does not function. Can't even ping the router. What is strange is that disabling wireless with the hardware switch and enabling it again doesn't help. The only way to make it works again: - Reboot - Disable wifi with hardware switch AND disable the network card in Device Manager, then enable both I did not have this problem on the very same laptop when it was running Windows 7. Any hint how can I find where the problem is?

• Using mod_rewrite for a Virtual Filesystem vs. Real Filesystem

  - by philtune

  I started working in a department that uses a CMS in which the entire "filesystem" is like this: create a named file or folder - this file is given a unique node (ex. 2345) as well as a default "filename" (ex. /WelcomeToOurProductsPage) and apply a template assign one or more aliases to the file for a URL redirect (ex. /home-page-products - can also be accessed by /home-page-products.aspx) A new Rewrite command is written on the .htaccess file for each and every alias Server accesses either /WelcomeToOurProductsPage or /home-page-products and redirects to something like /template.aspx?tmp=2&node=2345 (here I'm guessing what it does - I only have front-end access for now - but I have enough clues to strongly assume) Node 2345 grabs content stored in a SQL Db and applies it to the template. Note: There are no actual files being created on the filesystem. It's entirely virtual. This is probably a very common thing, but since I have never run across this kind of system before two months ago, I wanted to explain it in case it isn't common. I'm not a fan at all of ASP or closed-sourced systems, so it may be that this is common practice for ASP developers. My question, that has taken far too long to ask, is: what are the benefits of this kind of system, as opposed to creating an actual file hierarchy? Are there any drawbacks to having every single file server call redirected? To having the .htaccess file hold rewrite rules for every single alias?

• Help with user login on Centos 5.6

  - by Owen

  I added a user for the sole purpose of using SU for root. I did not allow the creation of a home directory when creating the user. So now when I login as this user I get the following: Could not chdir to home directory /home/MYUSERNAME: No such file or directory Couldn't resolve homedir for current user at - line 0 BEGIN failed--compilation aborted. Couldn't resolve homedir for current user at - line 0 BEGIN failed--compilation aborted. Is this an error, and if so how do I fix it so it is not looking to "resolve" the homedir?

• How to perform a nested mount when using chroot?

  - by user55542

  Note that this question is prompted by the circumstances detailed by me (as Xl1NntniNH7F) in http://www.linuxquestions.org/questions/linux-desktop-74/boot-failure-upon-updating-e2fsprogs-in-ubuntu-10-10-a-947328/. Thus if you could address the underlying cause of the boot failure, I would very much appreciate it. I'm trying to replicate the environment in my ubuntu installation (where the home folder is on a separate partition) in order to run make uninstall. I'm using a live cd. How to mount a dir in one partition (sda2, mounted in ubuntu as the home folder) into a directory on another mounted partition (sda3)? I did chroot /mnt/sda2 but I don't know how to mount sda3 to /home, and my various attempts didn't work. As I am unfamiliar with chroot, my approach could be wrong, so it would be great if you could suggest what I should do, given my circumstances.

• NetworkManager detects no networks with a RTL8188CE

  - by Cormac O'Brien

  I'm on a 2011 Lenovo Thinkpad T420i with a Realtek RTL8188CE WiFi adapter. Here's the scenario: I pop in the Ubuntu LiveCD to install. Laptop detects all networks in range, I connect to my home network, internet working great. Once Ubuntu finishes installing, the home network I am connected to is the only one which appears in the applet list. Upon restarting or waking from suspend, NetworkManager does not detect any networks – it simply displays "Disconnected" under the Wireless Network section of the menu. I am able to connect to my home network by using the "Connect to Hidden Wireless Network" option and it works immediately. I have yet to test if this works with other SSIDs. I have tried reinstalling the entire OS as well as NetworkManager and my wireless drivers. For hardware info, I ran: cormac@cormac-T420:~$ sudo lshw -c network Here is the output for my wireless card: *-network description: Wireless interface product: RTL8188CE 802.11b/g/n WiFi Adapter vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:03:00.0 logical name: wlan0 version: 01 serial: d0:df:9a:08:73:50 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=rtl8192ce driverversion=3.2.0-26-generic firmware=N/A ip=192.168.1.138 latency=0 link=yes multicast=yes wireless=IEEE 802.11bgn resources: irq:17 ioport:5000(size=256) memory:f2500000-f2503fff I can provide more information if required. This was not a problem in Natty or Oneiric. I hope this can be fixed, I don't want to have to ask for an SSID wherever I need to connect.

• Microsoft Office tracking license marks/keys in saved files (doc/docx/xls etc.)?

  - by pawel159

  Does Microsoft Office use any marks/keys in saved files, that can track the computer and software license using which file was saved? E.g.: I use Office at work and save files on pendrive. When I'm home I recall to check something and introduce little modifications. I'd save this file using MS Office Home and Student license, but at work I will be redistributing this file and it should look as it was saved at work, with company's license (not my private). Will saving it at work once again wipe license marks from home (if any exist)?

• Managing multiple ssh keys

  - by Mathijs Kwik

  I have a lot of ssh keys, they are all passphrase protected and managed by ssh-agent. As a result of this, I am now getting "Too many authentication failures" on some connections. As has been explained on this site before, this is because ssh will try all keys the agent throws at it. The proposed solution is to use IdentitiesOnly in the config, together with an IdentityFile. While this indeed stops offering wrong keys, it seems it completely disables the agent in full, so now I have to type the passphrase on every connection. I could not find clear info about this. Does IdentitiesOnly just disable getting keys from ssh-agent in full? Or should it just block out the keys that aren't mentioned? Thanks, Mathijs # here's my config ~% cat .ssh/config Host bluemote HostName some.host.com IdentitiesOnly yes IdentityFile /home/mathijs/.ssh/keys/bluebook_ecdsa # I had the key loaded into the agent, shown here ~% ssh-add -L ecdsa-sha2-nistp521 SOME_LONG_BASE64_NUMBER== /home/mathijs/.ssh/keys/bluebook_ecdsa # but it doesn't seem to get used ~% ssh bluemote Enter passphrase for key '/home/mathijs/.ssh/keys/bluebook_ecdsa':

• Can I move a copy of Windows 7 from one machine to another?

  - by Chopper3

  This is a pretty basic question sorry but I've looked in the 'related questions' and couldn't find an answer. When Windows 7 came out I bought a copy of Home Premium, the retail box with both 32 and 64 bit versions, to install via Boot Camp on my macbook. I've just got a retail (32 and 64 bit) copy of Windows 7 Ultimate that I'd like to install instead-of/over the Home Premium version and it struck me that I should, at least in principal be able to install the Home Premium version on my son's machine - is this the case and if so is there anything I should do first or once they're installed to let MS know I'm being a good guy about this? Sorry it's such a dim question but I'm a serverfault guy really and know very little about Windows. Thanks.

• Tricking Linux apps about current time with environment variables

  - by geek

  Sometimes it is possible to trick a Linux app by calling it like this: HOME=/tmp/foo myapp This would make myapp think /tmp/foo is the home directory, it won't try to get the user id, find its home directory via getpwent(). This is useful when myapp must be forced to dump some of its config files into a non-standard location different than ~. A similar trick can be done like this: LANG=foo LC_ALL=bar myapp This is useful when myapp needs to be called once with a different locale without having to make the change persistent by using the export bash built-in or even modify stuff in /etc/profile. Is it possible to pull the same trick with time and date? The goal is to make an app use another time than the system ones. The final goal - to make timestamps that appear in logs/commit messages not being tied to the system time.
