• How can I change ACLs recursively using cacls.exe?

  - by maaartinus

  I want to restrict the access for everything inside the work directory to me and the system only. I tried this with the following command: cacls.exe work /t /p 'PIXLA09\Maaartin:f' 'NT AUTHORITY\SYSTEM':f However it doesn't work at all. The following command should show only the two specified users but instead shows a very long list of permissions: cacls.exe work/somedirectory I tried to use /g instead of /p, too. Since I didn't use /e the permissions shouldn't get edited but replaced. Any ideas what's wrong?

• Open a custom remote powershell remotely

  - by Yann

  I have 2 computers. On the computer A, I have a custom module written in C# for powershell 3.0 and installed via a MSI. I also have a shortcut that open powershell with the module already loaded. I can just double click on my shortcut and run my command Do-Something on this computer without any problem, like the Exchange Server powershell. But now I would like to do it from a remote session on computer B in C#. So my question is, how can I open a remote powershell session to computer A with my module already loaded and the shell configured so I can just run my command and obtain the same result than if I run it on computer A?

• ntbackup workalike for adhoc full backups in Windows 7 thats free and preferably open source

  - by Justin Dearing

  On windows 2000 and XP machines I used to be able to do the following: ntbackup backup systemstate c: /f e:\backups\machineName\machineName-full+systemstate_200101206.bkf This gave me a full backup of the system that I could use to do a system restore, after doing a barebones OS install. Windows 7 has a great utility for regular backups with alerting and all that stuff. It does not seem to have command line support. I'd like a backup solution for my Windwos 7 systems that has the following features: Is free Is open source (preferebly) Works while the system is booted and leaves the system functional (clonezilla is great for offline backups, and I use that too) Gives me a backup that is suited for a full system restore or partial system restore (ruling out most imaging software even if they could work while the system is booted via some sort of shadow copy voodoo) Can work via the command line Compression would be nice, the ability to pipe output would be better.

• Network: Incoming connections work, outgoing fails

  - by anirvan

  i recently set up my own server at home to run Ubuntu 12.04 server ed. on booting up, i noticed that a message related to networking comes up, and the booting process pauses. the message read something like - waiting for network configuration and after a while - waiting another 60 seconds... on booting up, I realised that any command which requires a network connection was not working - ping, apt-get install, etc. on firing the ifup eth0 command, I get the error RTNETLINK answers: File exists. Failed to bring up eth0. I also realised, while searching the web for this problem, that this is probably one of the most common networking related issues - however, most of the questions are around setting up multiple IPs for the same machine. ifdown eth0 also fails, stating that eth0 is not configured. my /etc/network/interfaces file has a simple configuration for a static IP: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address xx.xx.xx.xx netmask xx.xx.xx.xx broadcast xx.xx.xx.xx gateway xx.xx.xx.xx dns-nameservers xx.xx.xx.xx The strangest part of this problem is that, while I can't connect to anything outside, I can ping to this particular server using the static IP configured in the interface file, and, i can even SSH into it! I'm really at ends here with this problem, and any guidance is much appreciated. Thanks!

• unable to send mail from postfix on Ubuntu 12.04

  - by gilmad

  I'm trying to send an email through Google from my localhost. (via PHP5.3) But Google keeps on blocking my requests. I tried to follow the solutions given to a few similar questions, but for some reason they do not work. I followed these instructions to configure it - http://www.dnsexit.com/support/mailrelay/postfix.html Now for the config data: my main.cf file looks like that: relayhost = [smtp.gmail.com]:587 smtp_fallback_relay = [relay.google.com] smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = my sasl_passwd looks like that: [smtp.gmail.com]:587 [email protected]:password and that is how the mail.log rows look like: Dec 14 10:24:50 COMP-NAME postfix/pickup[5185]: 1C3987E0EDD: uid=33 from= Dec 14 10:24:50 COMP-NAME postfix/cleanup[5499]: 1C3987E0EDD: message-id=<[email protected] Dec 14 10:24:50 COMP-NAME postfix/qmgr[5186]: 1C3987E0EDD: from=, size=483, nrcpt=1 (queue active) Dec 14 10:24:50 COMP-NAME postfix/smtp[5501]: 1C3987E0EDD: to=, relay=smtp.gmail.com[173.194.70.109]:587, delay=0.61, delays=0.19/0/0.32/0.1, dsn=5.7.0, status=bounced (host smtp.gmail.com[173.194.70.109] said: 530 5.7.0 Must issue a STARTTLS command first. w3sm8024250eel.17 (in reply to MAIL FROM command)) Dec 14 10:24:50 COMP-NAME postfix/cleanup[5499]: C20677E0EDE: message-id=<[email protected] Dec 14 10:24:50 COMP-NAME postfix/bounce[5502]: 1C3987E0EDD: sender non-delivery notification: C20677E0EDE Dec 14 10:24:50 COMP-NAME postfix/qmgr[5186]: C20677E0EDE: from=<, size=2532, nrcpt=1 (queue active) Dec 14 10:24:50 COMP-NAME postfix/qmgr[5186]: 1C3987E0EDD: removed

• Deleting Time Machine in Mac OS X 10.6.4

  - by cappuccino

  Does anyone know how to delete Time Machine in Mac OS X 10.6.4? Before answering: sudo rm -rf /whateverthetimemachineis does not work Disabling the ACL permissions first with sudo fsaclctl -p /whatever -d does not work, sudo: fsaclctl: command not found Use the delete all backup feature in Time Machine... this is slow as hell, would take days. Need a command line solution. No I don't want to reformat the drive, I have other content on it, and no don't say I should have separated on two partition or two drives, I did it this say since partitions cannot be dynamically changed, and two drives is annoying since, whats the point of having a big drive?... plus has no relation to the issue at hand. Already googlied for hours and read everything on Super User, nothing working. and all solutions are the first 4. Any clues?

• How to check if redis master is OK?

  - by e-satis

  On the documentation, they advice the monitor command. But it has a 50% performance penalty for the whole system, and how should I do that ? Whatching the ouput using SSH until I don't see anything ? Let's say I have 3 servers: 1 with a redis master, 1 with a redis slave, and one with my website querying the redis master. How can I, from my website server, make cleany the decision to fallback to the slave by sending the SLAVEOF NO ONE command ? My first step would be to put some kind of timeout check with a simple ping, just to be sure the server is online. But for redis specifically, I have no clue.

• How do I update my servers' domain name for Reverse DNS?

  - by Jeff

  I'm updating my mail servers' rDNS and I think I have it all figured out except for one thing. When I installed my OS (Debian Etch), the installer asked me to enter the "domain name". Is the "domain name" updated by using the hostname command? If so, which config file(s) are updated when using the hostname command? If not, how do I change my servers' domain name? My current /etc/hosts: 127.0.0.1 localhost 67.228.178.164 mrspock.example-old.com mrspock My current /etc/hostname: mrspock $ hostname -f mrspock.example-old.com I need to update hostname -f to be mrspock.example-new.com.

• Scanning php uploads in tmp directory with clamdscan fails

  - by Nikola

  I can't seem to get this thing to work, some permission problem maybe, but i can't even run clamdscan normally form console with root the result is always Permission denied. for example i create a file test.txt (eicar file) in /tmp and execute "clandscan /tmp/test.txt" in console logged in as root and i get "/tmp/test.txt: Access denied. ERROR ". The clamd demon is running with user clamav could that be the reason? Now i want to scan the same file (/tmp/test.txt) via php , so i run (i have chowned the file to apache:apache ) $cmd="clamdscan /tmp/test.txt"; exec($cmd,$a,$b); i get error 127 i try with the full path of the command /usr/bin/clamdscan i get error 126 (command is found but is not executable), this means that apache doesn't have the permission to execute /usr/bin/clamdscan ? what could be the problem?

• What tool can I use to definitely kill a process on Windows?

  - by Moak

  Can anyone recommend an application (preferably usb-portable that doesn't require setup) That really kills a process immediately in windows XP? I ask this because often when I need to use the XP task manager it seems to want to go about it "the polite way" and sometimes crashed programs don't quit or take a minute to shut down. I need a real stone cold killer, not a pushover-could-you-please-quit-now-no?-ok-sorry-program Edit I'm sorry if it wasn't clear previously but I did mean the situation when even the "End process" command in Process tab of the task manager doesn't kill a program, however one of the answers did point me to the "End Process Tree" command which I've never noticed (when right clicking on the process)

• Restore files from certain increments using Duplicity

  - by luckytaxi

  Given the following backup sets ... Found primary backup chain with matching signature chain: ------------------------- Chain start time: Tue Jun 21 11:27:26 2011 Chain end time: Tue Jun 21 11:27:59 2011 Number of contained backup sets: 2 Total number of contained volumes: 2 Type of backup set: Time: Num volumes: Full Tue Jun 21 11:27:26 2011 1 Incremental Tue Jun 21 11:27:59 2011 1 If i run the following command, it works (1308655646 was converted from Tue Jun 21 11:27:26 2011): duplicity --no-encryption --restore-time 1308655646 --file-to-restore ORIG_FILE \ file:///storage/test/ restored-file.txt However, if I run the following command, it restores the from the latest set. duplicity --no-encryption --restore-time 2011-06-21T11:27:26 --file-to-restore \ ORIG_FILE file:///storage/test/ restored-file.txt What am I doing wrong w/ the time? I prefer the second option only because I don't want to have to do the conversion manually.

• Looking for a router-like web interface for my Debian gateway.

  - by marcusw

  Hey, I need a web interface program for my debian gateway which has the features of a router's one. Specifically, I must be able to easily Forward ports to various clients on the LAN or the router itself (it's also a server) Manage a DHCP server preferably including DHCP reservation for certain MACs Give me a list of the connected DHCP clients (optionally) Show which clients are the most active as far as bandwidth (something like iftop) Alternatively, it could be a graphical app which I could tunnel over ssh. No command line programs please...I'm used to doing this stuff with a point-and-click interface. Not adverse to command-line setup; just need to be able to reconfigure things graphically. Have a working LAMP setup. I've tried webmin, but it didn't satisfy the "easy" part...too many clicks and too many meny options.

• I just recursively chmod'd everything under / to 750. Any tips?

  - by Ouairz

  I won't be the first and I won't be the last, I suppose. While playing around with the find command, I made a whoops and it would appear that instead of changing the permissions of the ~/web directory to 750, it changed the permissions of the entire filesystem (/) to 750, however I'm not certain, but any attempt to investigate is thwarted by Permission denied messages. For everything. This was the offending command: sudo find ~/web . type d -exec chmod 750 {} If I'm not mistaken, the Ubuntu team disabled root logins as a safety precaution so I'm out of ideas. I'm (obviously) a total newbie when it comes to file permissions so I was wondering if anyone had some good or even some bad advice to share. I've mentally prepped myself to losing everything on the computer which is only of mild consequence, since I have backups, but I did do a bit of work on this box over the week and it would be a shame to lose it all due to a boneheaded mistake. If you are reading this message, ask yourself, have you backed up any of your work recently? Thanks in advance for any insights. Feel free to scold me for using sudo carelessly

• Red Hat 5.4 slow processing

  - by yucefrizk

  I'm running Red Hat Linux 5.4 on HP DL580 server with 16 processors and 64 GB of RAM. I'm connecting to the server remotely through SSH. after entering the password, it takes time to return the command line, if I click ctrl+c during this time, I'll have the command line prompt but not the correct bash prompt (I have to run bash to pass to my correct prompt). I tried to install Apache on the server, ./configure took 4 hours to finish instead of 1 or two minutes, Oracle installation same behavior. Server Disks are mirrored using RAID controller. any idea what could be the reason of this slowness?

• Flush mod_pagespeed cache in Debian

  - by Ivar

  I need a way to flush the mod_pagespeed cache while developing. According to mod_pagespeed documents, I should run the following command: sudo touch /var/mod_pagespeed/cache/cache.flush In Debian it's "su" instead of "sudo". However, it doesn't work for me; there's no "touch" command, nor is there any "cache.flush" file in the defined directory. Have I missed something? You kick-ass Linux users, please be humble - I'm pretty new to these stuff. Thank you in advance!

• How to pipe differently the body of the curl answer and the printed output?

  - by Antoine Lizée

  I would like to print in the command line some output of curl, like the http headers, followed by the body of the answer processed by a stdin/stdout program. For instance: Print the status code: curl -s -w "%{http_code} \\n" -o "/dev/null" http://myURL.com And then process the output with a json parsing tool: curl -s http://myURL.com | python -mjson.tool I would like to do both with one command, and I have the feeling that it may be possible thanks to the -o option that makes the difference between the output of curl and the actual answer from the query. The problem is that -o writes directly to a file. Somebody's got a hack?

• How can I copy a SQL Azure Database to a server on a different subscription?

  - by Tragedian

  I'm trying to create a copy of a SQL Azure database. The source and destination servers are associated with two different subscriptions, but they are located in the same data-centre. I've been reading Copying Databases in Windows SQL Azure Database and How to: Copy Your Databases (Windows Azure SQL Database) for instructions on this, but I'm not sure if my scenario is covered. I would like to use the CREATE DATABASE Database1B AS COPY OF Database1A; command, but I don't know what the implications are on the accounts used, or what I need to set up between the two databases before this command is possible. Has anybody achieved this type of copy and can elaborate?

• startx error no desktop manager

  - by WikiWitz

  I have Backtrack 5R2 KDE. I started recovery mode and did a failsafe xorg configuration. After that, I cannot load the KDE manager when I enter the startx command after logging in. Whenever I do a startx command (as root), the result resembles the following: This is not the actual output (I just drew this with MS paint because I cannot do a printscreen). The screen is just black with the icon in the upper left corner. The other pop-up menu appears when left-clicking the mouse. I tried the cp xorg.conf.failsafe xorg.conf advice from other websites with no luck. I have also tried the 'reconfigure option(s)' form the recovery mode with no success.

• Uninstalling ATI's drivers and installing NVIDIA's?

  - by whydidithavetobreak

  I replaced my card but I'm not sure how to set things up on Ubuntu. When the computer boots, it doesn't start GDM (I think that's what it's called). Instead, it asks me to log in the command line. If I try to do a startx, it tells me there is no AMD device connected or something to that extent. I originally installed the ATI drivers using the GUI. It said that I was using the limited drivers or something to that extent with a popup on the right of one of the taskbars, so I clicked there and updated it. I think it could also be reached by going to system administration restricted drivers or something close to that. I tried installing the nivida drivers by doing a "sudo apt-get install nvidia-glx-185" and then doing "sudo modprobe nvidia" and "sudo nvidia-xconfig" as this guy says but that didn't work. Modprobe couldn't find anything related to Nvidia and nvidia-xconfig wasn't an available command for me. Since I wasn't sure how to remove the ATI drivers I did that without messing with them. Not sure if that was a good idea.
