• Windows - Decrypt encrypted file when user account is destroyed

  - by dc2

  I have a Virtual Machine running on my Windows Server 2008 computer that originally was received by me encryped, as the builder of the VM did it on a MAC, which decrypts files by default. I never thought to decrypt these files, as they automatically 'decrypt' when you have permission over them, so the VM has been running for over a year despite the encryption. I just upgraded my computer to Domain Controller (dcpromo.exe). Now when I try to access/run the VM, I can't because I don't have permission to decrypt the files as that was on another logon (local administrator) and now I am the domain administrator. Apparently the local admin is totally nuked when you upgrade to domain controller. I have tried EVERYTHING - taking ownership of the files, which works. Doesn't do anything for me. Adding full control to everyone on the files. I go to File Properties Advanced Details (under encryption) Users who can access this file. The only user is administrator@localcomputername, and there is a cert number. I try adding a new cert, I don't have permission. I don't have permission to: Decrypt the file (access is denied). Copy the file (to another computer) - access denied. I am totally stumped and this VM is a production machine and needs to get up right now. Does anyone have any ideas?

• DRBD as a block device for XEN VM (Centos 5.3)

  - by SaberTooth

  Hi all, I have setup a drbd resource between 2 server nodes - everything works correctly when doing sync tests between the two. (I want to create a HA cluster using drbd,xen and heartbeat) However, when I try and create a XEN VM with Centos as guest operating system, I get through to the partitioning screen on the install but when I select a partitioning type the next screen gives me the following error : "An error has occurred - no valid devices were found on which to create new file systems. Please check your hardware for the cause of this problem." This is the first time attempting create a setup like this and searching Google does not help much... my config files for DRBD and XEN....

• How would I write a terminal command to download a folder with wget from a Media Temple (gs) server?

  - by racl101

  I'm trying to download a folder using wget on the Terminal (I'm usin a Mac if that matters) because my ftp client sucks and keeps timing out. It doesn't stay connected for long. So I was wondering if I could use wget to connect via ftp protocol to the server to download the directory in question. I have searched around in the internet for this and have attempted to write the command but it keeps failing. So assuming the following: ftp username is: [email protected] ftp host is: ftp.s12345.gridserver.com ftp password is: somepassword I have tried to write the command in the following ways: wget -r ftp://[email protected]:[email protected]/path/to/desired/folder/ wget -r ftp://serveradmin:[email protected]/path/to/desired/folder/ When I try the first way I get this error: Bad port number. When I try the second way I get a little further but I get this error: Resolving s12345.gridserver.com... 71.46.226.79 Connecting to s12345.gridserver.com|71.46.226.79|:21... connected. Logging in as serveradmin ... Login incorrect. What could I be doing wrong?

• PST backup with Volume Shadow Copy Service

  - by NoMadMan

  I was asked to implement the task of backing up 35 PST files ranging from 800Mb to 2000Mb. Windows XP and Windows 2000 workstations are assigned to the users and we have a Windows 2000 domain controller we use to back up files on 3x 500Gb external hard drives. I found several methods from applications to scripts. Local or remote applications would be my last resort. I came across this script based on Volume Shadow Copy Service. CopyWithVss I wanted to know if there would be a problem if the path had spaces. Would mounting the destination path of each PST folder with a drive letter be more practical? My concern with mounting option is that i would eventually run out of letters since I have 35 and possibly more workstations to back up. Lastly, can someone give me an example of CopyWithVss if it were run on a production network? The script is a bit cryptic even after reading several times. Where in the script do I enter the source and the destination? I'm a Mac user so please excuse my ignorance with Windows platform.

• Apache, Permissions, and Convenience

  - by Mike

  I'm on Mac OSX and i I have apache2 installed via MacPorts, running as the _www user. I have some files I want to serve in the /Users/Me/Documents/abc folder. Right now, though, the permissions of /Users/Me/Documents are 700. So, _www can't get in, even if abc is chmod 777. I recognize the following options: Allow _www access to my Documents folder. Put the files I want to share outside of my Documents folder. Hard-link the files outside of my Documents folder, and point apache to the hard links. None of these solutions are acceptable to me, however. I don't feel safe allowing _www access to my entire Documents folder. I really want to keep the files in my Documents folder for other reasons. The files are changing all the time, so hard-linking would not always reflect the right file structure, and, as I understand it, you can't hard-link a directory (though, if you could, that would solve it). Any ideas for a solution? Is there a way to run a few httpd processes as my user account so it can get in there? Or, is there some way to hard-link a directory, or some way to get httpd to follow a symlink past a directory that is 700 not owned by _www? Thanks!

• Linux file server for an inexperienced admin

  - by Pat

  A charity I volunteer for wants a file server for their mostly Windows machines (about five XP and 7 machines, with some Mac laptops every now and then). For the server, I have a PC with an Intel Core 2 Duo 3GHz proc, 4GB of DDR2 400MHz RAM, and a 500 GB HDD. (I should point out that they do not currently have any server - they are just using Windows to share a folder on one of the PCs.) What is a linux distro that is easy to configure for Windows file serving yet stable and secure enough to protect sensitive data without an expert sysadmin? I'm guessing that a Debian distro would probably fit the security bill, but I don't know of any tailored to novice sysadmins. Also, are there any killer apps for making this easy to administer and set up (as a Windows file server, in particular - this answer is a good example)? Would FreeNAS be sufficient? Once it's all set up, what are the minimum measures I need to take to keep the data secure? I found this somewhat helpful answer, but it's not specific to my question of just getting a secure file server up, running, and maintained.

• Separated virtual networks with same subnet range with 2 interface

  - by Coolpet

  I'm having some problems with routing with the following: I have a server with 2 interfaces. It has 1-1 alias contains the same subnet. the 2 interface is connected to 2 switch, which are separated from each other. Infrastructure: Eth0 192.168.16.2/20 Eth0:eth0 192.168.1.222/20 Eth1 192.168.32.3/20 Eth1:eth1 192.168.1.223/20 I have a PC which has the IP address: 192.168.1.3/24 The problem is the next: If PC is on subnet 1, I can ping it. If PC is on subnet 2, I can't ping it. traceroute shows the route is across 192.168.1.222 ping -I 192.168.1.223 192.168.1.3 is not working on subnet 2. arp entries show the MAC address belonging to the correct interface (eth1 on subnet 2) How can I force the server to look on both interface same ranged subnet for specific IP? It searches only in the first subnet. The routing table has these 2 entries: 192.168.0.0/20 dev eth0 proto kernel scope link src 192.168.1.222 192.168.0.0/20 dev eth1 proto kernel scope link src 192.168.1.223

• Ubuntu + LigHTTPd: Server requests taking ages

  - by ctrl_freak

  I've had an issue since upgrading my distro a couple of weeks ago from hardy; receiving data after making a request has increasing intervals of nothing, as you can see from the picture below. http://i49.tinypic.com/2w5lvr9.png I have since reinstalled fresh from an Ubuntu 10.04 Server (i386) disk, but am still having the same issues. I'm running on a LigHTTPd, MySQL, PHP5 stack. The surprising thing is, that local browsing using lynx is super fast, as expected. Initially, after reinstalling, I copied over the old configuration files from the previous installation, but have since reinstalled LigHTTPd and rebuilt the config file from scratch. The only correlation I could find, was that I attempted installation of ionCube and Zend Optimizer for a script I was testing, however I would think that it could no longer impact seeing I had reinstalled the OS. I have also removed Suhosin just in case, however it had no impact. I'm thinking it possibly has something to do with networking, but I wouldn't know where to start. The server is manually assigned an IP by it's MAC address on the router. The fact that the time seems to be exponential (to a point) worries me. I've tried strace'ing the LigHTTPd and MySQL processes, however I couldn't see anything obvious, not that I'd really know what I'm looking for. RAM and CPU usage don't seem to be out of the ordinary, but I can't say its perfect.. I'm hoping someone has experienced the same, or can point me in a direction, as searching has proved fruitless as I don't know anything specific. Config files can be posted, if requested.

• Eclipse CDT wont recognize standard library

  - by Mike G

  I work primarily on my desktop, but I started working on my mac laptop and noticed a problem with eclipse CDT. The standard library was underlined yellow and cout wouldn't work (It wouldn't recognize/find it). I tried restarting the program and that didn't work. I then tried to see if xcode would work, found that the version of xcode was too old, and updated xcode. Eclipse still didn't work, but xcode did. I tried re-installing eclipse to the new version and re-installing cdt. It still wouldn't work. Restarting my computer wont work either. I'm not sure if this helps (or even matters/applies) but when I type g++ --version into terminal, it doesn't work. (I don't know if that matters but some tutorial told me to do that to check if the compiler was working). So, in review, I have: Re-installed eclipse Restarted my computer Re-installed xcode (which I think has all the compilers eclipse uses.) Updated Eclipse Typed g++ --version to test compiler.

• Is there a way to do a sector level copy/clone from one hard drive to another?

  - by irrational John

  Without going into distracting details, I'm attempting to duplicate the contents of the 500GB drive in my MacBook to another 500GB drive. But this is turning out to be an unexpected hassle because the drive contains both the OS X partition and an NTFS partition with Win 7 via Apple's Boot Camp. With the exception of Clonezilla, the tools I have looked at so far all have some limitation. The Mac tools don't want to deal with the NTFS partition. The Windows tools are totally clueless about either the HFS+ partition and/or the hybrid MBR/GPT Boot Camp partitioning. Clonezilla looked like it would do what I want but apparently I can't figure out how to use it. After doing what I thought was a sector to sector copy I found that only the NTFS partition had been migrated. The others were apparently empty. (And frankly, I'm not positive Clonezilla migrated the partition table correctly either). Note: It takes over 2 hours using SATA to read/write all sectors with these drives. So I'm not up for using trial & error to narrow in on the right combination of Clonezilla options to use. I'm beginning to think that maybe the answer is to boot Linux (probably Ubuntu) and then use some ancient BSD command. Trouble is I don't know what command (or parameters to use) in order to do a sector level copy from one drive to another. As far as I know the drives have the same number of sectors so this should be trivial. Sigh.

• Ubuntu Launcher Items Don't Have Correct Environment Vars under NX

  - by ivarley

  I've got an environment variable issue I'm having trouble resolving. I'm running Ubuntu (Karmic, 9.10) and coming in via NX (NoMachine) on a Mac. I've added several environment variables in my .bashrc file, e.g.: export JAVA_HOME=$HOME/dev/tools/Linux/jdk/jdk1.6.0_16/ Sitting at the machine, this environment variable is available on the command line, as well as for apps I launch from the Main Menu. Coming in over NX, however, the environment variable shows up correctly on the command line, but NOT when I launch things via the launcher. As an example, I created a simple shell script called testpath in my home folder: #!/bin/sh echo $PATH && sleep 5 quit I gave it execute privileges: chmod +x testpath And then I created a launcher item in my Main Menu that simply runs: ./testpath When I'm sitting at the computer, this launcher runs and shows all the stuff I put into the $PATH variable in my .bashrc file (e.g. $JAVA_HOME, etc). But when I come in over NX, it shows a totally different value for the $PATH variable, despite the fact that if I launch a terminal window (still in NX), and type export $PATH, it shows up correctly. I assume this has to do with which files are getting loaded by the windowing system over NX, and that it's some other file. But I have no idea how to fix it. For the record, I also have a .profile file with the following in it: # if running bash if [ -n "$BASH_VERSION" ]; then # include .bashrc if it exists if [ -f "$HOME/.bashrc" ]; then . "$HOME/.bashrc" fi fi

• Are there tools available for trimming PDF margins?

  - by Charles Duffy

  I have an ebook I'm trying to read in PDF format on a Kindle. Unfortunately, the page headers and footers have some content (page number and copyright info, respectively) preventing the device from scaling the actual text to match its usable area viewing area, thus leaving the actual content too small to read. Various tools are available which will trim off whitespace, but the Kindle already does this; my goal, by contrast, is to remove printed matter outside of a defined bounding box, and the only tool I've found for the purpose is moderately expensive commercial software. I could probably generate a mask in Inkscape; split out the individual pages using pdftk, apply the mask to each page individually (outputting to postscript), and recombine the numerous postscript files into a single PDF. However, this decode/reencode steps would be pretty unfortunate in terms of document size; something able to operate with a bit more finesse would be ideal. I have all major operating systems handy (Windows, several modern Linux distros, a Mac, etc) so solutions don't need to be constrained by platform. Suggestions? (I've reported the issue to the author, who mentioned it to his editor, who hasn't done anything about the issue over the course of more than a month, making the zero-work approach evidently nonproductive).

• Redhat Linux password fail on ssh

  - by Stephopolis

  I am trying to ssh into my linux machine from my mac. If I am physically at the machine I can log in with my password just fine, but if I am sshing it refuses. I am getting: Permission denies (publickey,keyboard-interactive) I thought that it might be caused by some changes that I recently made to system-auth, but I restored everything to what I believe was the original format: #%PAM-1.0 # This file is auto-generated. # User changes will be destroyed the next time authconfig is run. auth required pam_env.so auth sufficient pam_fprintd.so auth sufficient pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 500 quiet auth required pam_deny.so account required pam_unix.so account sufficient pam_localuser.so account sufficient pam_succeed_if.so uid < 500 quiet account required pam_permit.so password requisite pam_cracklib.so try_first_pass retry=3 password sufficient pam_unix.so md5 shadow nullok try_first_pass use_authtok password required pam_deny.so session optional pam_keyinit.so revoke session required pam_limits.so session [success=1 default=ignore] pam_succeed_if.so service in crond quiet use_uid session required pam_unix.so But I still could not ssh in.

• VirtualName-based local development host behind corporate proxy (MAMP)

  - by geerlingguy

  I am behind a corporate proxy server/firewall, and this firewall seems to not be too happy with my idea of local development. On my home computer (Mac/Leopard), I have MAMP running, with a rule in /etc/hosts that directs dev.example.com to 127.0.0.1, and I have a virtualhost set up in the httpd.conf file which works great for me. However, at work, I set up the exact same configuration, but am not able to access dev.example.com, likely due to some address/DNS translation going on via the proxy server. Here are the relevant details from Terminal: $ ping dev.example.com PING dev.example.com (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.025 ms $ host dev.example.com Host dev.example.com not found: 3(NXDOMAIN) I've tried adding dev.example.com to the list of bypass addresses in System Preferences (the 'Bypass proxy settings for these Hosts & Domains' list), but that had no effect. Is there any way I can develop locally using name-based hosts at work? I can access localhost, but can't get to the dev.example.com (or any other custom virtualhosts) here at work, which complicates other matters related to the sites on which I'm working...

• Best solution top keep data secure

  - by mrwooster

  What is the simplest and most elegant way of storing a small amount of data in a reasonably secure way? I am not looking for ridiculous levels of advanced encryption (AES-256 is more than enough) and I am only looking to encrypt a small number of files. The files I wish to encrypt are mostly comprised of password lists and SSH keys for servers. Unfortunately it is impossible to keep track of ever changing passwords for my servers (and SSH keys) and so need to keep a list of the passwords. Obviously this list needs to be secure, and also portable (I work from multiple locations). At the moment, I use a 10MB encrypted disk image on my mac (std .dmg AES-256) and just mount it whenever I need access to the data. To my knowledge this is very secure and I am very happy using it. However, the data is not very portable. I would like to be able to access my data from other machines (especially ones running linux), and I am aware that there are quite a few issues trying to mount an encrypted .dmg on linux. An alternative I have considered is to create a tar archive containing the files and use gpg --symmetric to encrypt it, but this is not a very elegant solution as it requires gpg to be installed on every system. So, what over solutions exist, and which ones would you consider to be the most elegant? Ty

• Router(s) Issue: DNS quries sporadically fail with multiple computers hooked in

  - by bob-the-destroyer

  Basically, after anywhere from 5-60 minutes, DNS queries fail for a few minutes, then slowly begin to resolve correctly. Then the cycle repeats. This occurs only when more than one computer is on the network. All computers on the network experiences the same sporadic DNS outage at the same time. Wireless or wired, Linux or Windows, fresh OS install or old, browser or ping, same symptoms. Duplicated on 3 routers (not chained together, mind you) and 3 ISP's and 3 separate locations over the past several months. The only common theme is a single 5-yo WIN XP laptop which has been in use on the network throughout all this. There also may be anywhere between 1 - 10 devices hooked up wired or wirelessly at a time. The only reprieve I have from this torture is by using any VPN to an outside source - always smooth sailing. I typically set up any router to a) use WPA2/etc security; b) MAC whitelist; c) UPNP OFF (if available); d) always update firmware when available; e) obtain DNS from ISP automatically; f) set the router to act as DHCP server for the internal network. Adjusting channels has no effect. Any ideas?

• Advice on cloning disk

  - by hks

  I'm going to buy a second disk for backup, the same size as my laptops. I want to mount it in a casing via usb and backup an entire hdd every soemtime. That's because I want the posibility to just switch drives in case of something goes wrong. I'm using Linux and obviously the right tool seems to be dd. The thing is that my laptop drive has a speed of around 50-70 MB/s and usb 2.0 is 57 MB/s. So to copy my 250GB disk should take me more than 1 hour if I'm lucky. I can't wait this much. I want some differential backup. I read one of JWZ articles. In it he gives more details for using rsync on Mac. He writes that there is possibility of making rsync'ed disk bootable. So my question is: how to make rsync'ed hdd bootable under Linux or are there other 'quick backup' tools for Linux that would allow me to just swap drives? Or should I just stick to dd :( ?

• What needs to be considered when setting up for Linux Development? [closed]

  - by user123586

  I want to set up a box for Linux development. I have a working linux install with the usual toolchain and an IDE. I'm looking for advice on how to approach structuring accounts and folders for development. As the Perl folks say "There's always more than one way to do it." Left to my own devices, I'll come up with several unproductive ways of doing it before figuring out what an experienced Linux programmer would think obvious. I'm not looking for instructions to follow for a specific set of tools or a specific software package. Instead, I'm looking for insight into what decisions need to be made and how to make them, with understanding of the advantages and disadvantages of each individual choice. These are some of the questions that come up: Where to put sources Where to put built object files and libraries where to install what to set in environment variables what compiler flags matter and how do you manage them across several types of builds what configuration entries to make in an IDE how to manage libraries to support multiple environments how to handle different build versions such as debug vs release, or cross platform builds If you are an experienced Linux developer, the answers to these questions may seem trivial and obvious. I'd like to learn to make decisions about these questions that result in as little manual configuration as possible, given some existing sources, a particular IDE, or no IDE at all, a paticular set of development libraries etc. At this point you're probably thinking: Can you be more specific? Sure. But remember that I'm trying to learn how to think about this stuff, not just follow a recipie for a specific set of results. Example: Setup a project that uses CMake for some of its components, autogen.sh followed by configure for others and just configure for a few more: debug builds without an IDE debug builds in NetBeans debug builds in Eclipse debug build in Visual Studio all of the above with release builds for Linux, Mac and Windows. So... **What are your thoughts on an approach that works for all four? Do you have any advice on what to read?**

• Static DHCP binding

  - by Alex

  Good time of day, SF people. I have created a manual DHCP binding entry on a Cisco router so that a client would always get leased to it. The clients wants to get the same address on both of his dual-boot linux systems. He tries to get an IP address leased and he succeeds on one of the dual-boot operating systems. When he reboots to another one he gets a lease for a completely different one. I don't get it. The MAC addresses are the same (we checked in ifconfig, so what could be happening here? Why is the router confused? Or is it something else? Also, how can I check DHCP server IP address who I have got an IP address from (on Linux)? Configuration on Cisco: ip dhcp pool MANUAL_BINDING0001 host 192.168.0.64 255.255.255.0 hardware-address dead.beef.1337 dns-server 192.168.8.11 default-router 192.168.0.254 domain-name verynicedomainigothere.cn PS.

  - by Designer023

  I need to run an app at startup/login on my mac. I want it to launch in the background and start doing it's work without interrupting me or me having to start it up because I invariably forget and then when I need it, it wasn't running! I have tried using applescript to tell terminal to run it and type my password in, but it ends up opening multiple Terminal windows and not working. Ideally I need a script that I can just add to the user login items and it will run for me. The app has no way of taking a password argument either and it has a password as well as the sudo! I need a solution that can either be done as an applescript (which can be made into an executable) or i need a commandline script but I have no idea about them. This is the manual code I type >sudo serverStatus >password:123456 >password:serverpass Not sure if this is the right stack to ask, but I have no idea now and it's above my head! Thanks :D My applescript: tell application Terminal activate do shell script "sudo serverStatus" delay 5 do shell script "123456" delay 2 do shell script "serverpass" end tell

• Can't Ping - Wireless network of home

  - by Naunidh

  Hello, This may seem like other ping problem, but I have tried a lot before posting it here. I have a linksys WRT54G - firmware v8.00.8. I have two laptops one windows vista (192.168.1.99) and Windows Xp (192.168.1.13) connected on WiFi . The Router's IP address is 192.168.1.4, and default gateway is the ADSL modem (192.168.1.1) connected through wire. The problem is that laptops can not ping each other, they can ping the gateway and the linksys router, and both can access internet. Following has been tried (I am pinging from XP machine to Vista): I saw that arp entires for Vista machines were not being populated, so I added static ARP entries. 192.168.1.99 00-19-7e-70-d0-4e static I checked on ethereal that an ICMP packet for MAC address of Vista machine does go out from XP machine towards the Vista machine, but never reaches the Vista machine. So its get eaten by the Router? I added Vista machine to DMZ in my linksys router, so that all the ports are open (In case it was an issue). Firewalls , antivirus etc were turned off, echo was enabled explicitly on vista, file sharing, network discovery were turned on. Network type was set to private. Unchecked everything in Router;s firewall, even though they are only meant for WAN requests. Is there anything else that I should try. Thanks.

• How to backup Servers to an SSH-Host with low traffic and access to versions and encryption?

  - by leto

  Hello, I've not run backups for the past dont't remember anymore years for my personal stuff until waking up lately and realising contrary to my prior belief: Actually. I care! :) Now I have a central data server at home where I want to attach an external media to, to which I want to save backups of my most important stuff, like years of self-written scripts, database dumps, you name it. I've tinkered with rsync+ssh over the last two years, also tried tar over ssh, but don't know the simplest and most easy to maintain way to do it yet. Heres my workload: A typical LAMP-Server (<5GB Data) which I'd like to backup fully so lots of small files connected via 10Mbit My personal stuff (<750GB Data) from a Mac connected via GE My passwords in an encrypted container (100Mb) from OpenBSD connected via serial-PPP My E-Mail from the last ten years (<25GB) as Maildir which I need to keep in readable format Some archives (tar.*) which I need to backup only once and keep in readable format (Deleted my ideas, as I'm here for suggestions) What I need: 1. Use an ssh-tunnel for data transfer 2. Be quick with lots of small files 3. Keep revisions 4. Be sure the data I save is not corrupted 5. Intelligent resume functions and be able to deal with network congestion :) 6. Compressed and optionally encrypted storage 7. Be able to extract data from backup easily (filesystem like usage would be nice) How would and with what software would you backup this stuff? Hints to tools that can help solve only part of my problem (like encryption) also greatly appreciated. Greets

• using virtual machine like mySql server

  - by ffmm

  i'm developing a java program and i need a database. Now i'm using MAMP and it's pretty easy but i would have a virtual machine (ubuntu server) and i need to connect my java program with this virtual machine using vitualBox. the situation: I installed VirtualBox on my mac and I installed an ubuntu-server machine set "bridge adapter" in the network settings of VB I installed mysql on ubuntu-server and i created a simple database (all work well by ubuntu) doing ifconfig by ubuntu I get the ip: 192.168.1.217 so in the java program i made this function: public static Connection connect(String host, int port, String dbName, String user, String passwd) { Connection dbConnection = null; try { String dbString = null; Class.forName("com.mysql.jdbc.Driver").newInstance(); dbString = "jdbc:mysql://" + host + ":" + port + "/" + dbName; dbConnection = DriverManager.getConnection(dbString, user, passwd); } catch (Exception e) { System.err.println("Failed to connect with the DB"); e.printStackTrace(); } return dbConnection; } and in the main() i use: Connection con = connect(1, "192.168.1.217", 3306, "Ciao", "root", "cocacola"); 3306 was a default value. I don't know if is correct, it works on mamp, but…. how I can find the correct port that I have to use with VB? when I ran the program I get the catch excepion… what's wrong? ps: i have to install apache o something else?
