  • touch /forcefsck not working on Fedora16

    - by Harry
    I need to run fsck in order to repair my one and only hard-disk. I have no rescue CD/USB available. I did the following: touch /forcefsck chmod a+rw /forcefsck # just to be really sure reboot But no fsck happened on reboot, though the /forcefsck file quietly disappeared (why BTW?)! I saw some responses on the Net suggesting a shutdown -rF to auto-run fsck on reboot, but the shutdown I have on my F16 does not have any -F option.

  • Group readable cron jobs a security risk?

    - by Ibrahim
    Hi, I was just wondering, is using a cron job that is group readable a security risk? In this case, the script is chmod 755, and the group is basically a group of the sysadmins on the machine. The permissions seem to be fine, but I'm just wondering whether it's a bad idea to keep this script in a group or world readable place because it's a backup script that needs to be run as root. Thanks!

  • Why is setuid ignored on directories?

    - by Blacklight Shining
    On Linux systems, you can successfully chmod u+s $some_directory, but instead of forcing the ownership of new subdirectories and files to be the owner of the containing directory (and setting subdirectories u+s as well) as you might expect, the system just ignores the setuid bit. Subdirectories and files continue to inherit the UIDs of their creating processes, and subdirectories are not setuid by default. Why is setuid ignored on directories, and how can I get the system to recognize it?

  • Apache and file permissions

    - by Matthew
    I'm running LAMP on Ubuntu 8.04. Apache's username and group are www-data. I put my connection details and AES key in a file in a directory that's not web served. I chown-ed the files to www-data:www-data and set the permissions to 700. Still, the script that require()s these files will only run if I chmod the files to 755. What am I missing?

  • Not sure about ACL permissions

    - by Darko Miletic
    I'm writing up something about ACL usage on CentOS but since I still do not have a box ready I would like to ask something. Let us assume we have a folder /var/www/test If I do this in terms of permissions: /bin/chown -R root:root /var/www/test/ /bin/chmod -R u=rwx,go= /var/www/test/ /usr/bin/setfacl -R -m u:apache:rwx /var/www/test/ Will user apache be able to change owner of folder test or of any particular file within that folder? If answer is yes shall I than use group instead of user?

  • Can't chgrp in NFS4 mounts

    - by Philipp
    Hello, I'm using Linux in a large multi-user network. Let A be some group which I'm am member of, but which is not my primary group. According to chmod(2) I should be able to chgrp a file to group A. Trying to do so succeeds on a local as well as on a NFSv3 mount, but not on a NFSv4/Kerberos mount (EPERM). Are there any special considerations regarding chgrp when using NFSv4 mounts?

  • Ubuntu 9.10: how do I troubleshoot a startup script that doesn't appear to run?

    - by TheDeeno
    I've created a bash script 'foo'. I've made that script executable with chmod+x and added it the the start-up by running sudo update-rc.d foo defaults 80 Despite that, it doesn't appear to be working at startup. Is there a way to have my script echo messages to a log? Or is there some log that would record events/errors for this? atm, I feel like I'm flying blind and don't really know how to troubleshoot this.

  • File/folder permissions and groups on Linux with Apache

    - by phobia
    I'm trying to learn about permissions on linux webserver with apache. Some clues to the system: The server I have to play around with is Fedora based. Apache runs as apache:apache. To allow for e.g. php to write to a file the file needs to be chmod 777. 755 is not sufficiant. What I'm wondering is basically how set up permissions like they should be on e.g. a "shared web host". My main problem is that if I set a permission so that one user cannot access anothers home folder, then apache can't read from the public_html folder either. To keep the users out I need to set chmod 700. But to let apache to read I need to have at least execute on world, so a 701 basically works, but won't let some users in. So I'm really stuck on what to do. Have been concidering adding the apache user to the frous grours below to avoid having to add the world execute flag, but is that a bad thing? Should it be the other way around, the users in the groups below should also be in the apache group? I was aiming at having 4 groups: 1. webapp same as dev_int, but is the only one that can go inside the webapp/live folder to e.g. do an update from the repo. 2. dev_int can read,write and execute everything in the "web root", including the two below, but nothing outside of the web root 3. dev_ext can read write and execute in all client folders, but cannot access anything outside of the webapp root 4. clientsBasic ftp accounts. Has a home folder with a public_html, but cannot access any other home folders An example of folder structure: webroot    no users in the aforementioned groups can go outside of here some_project    :dev_int only webapp live    :webapp only staging    :dev_int and :dev_ext clients    :dev_int and :dev_ext client_1    :dev_int, :dev_ext and client1:clients public_html dev developer_1    developer_1:dev_int OR :dev_ext public_html

  • (Ubuntu) setuid bash doesn't work

    - by ???
    Here is the code: (root:) # mkdir /test # cp /bin/bash /test/sbash # chmod a+s /test/sbash (user1:) $ cd /test $ ./sbash $ mkdir trycreate mkdir: cannot create directory `trycreate': Permission denied And bash scripts with setuid bit set not work, either. By the way, my setuid perl script works: test.pl: (with setuid bit set, owner=root) #!/usr/bin/perl mkdir('/test/tryperlcreate') or die 'failed'; execute test.pl by user1 will create the directory owned by root.

  • virtual mac osx 10.6.8 in VMWare does not save screen captures

    - by epeleg
    I have a VMWare image of a mac OSX 10.6.8 (fully updated). When I click Commnd+Shift+3 it makes a camera shutter sound, but no screen-capture is saved anywhere that I can find. When running: defaults read com.apple.screencapture location it returns /Users/admin/Pictures/Captures this folder exists and is empty also executed chmod 777 /Users/admin/Pictures/Captures Any ideas anyone ? Could this be related to the VMware screen resolution(Size) of this MAC? (currently set to 1348x1391)

  • Reset ACLs in NFS4/ZFS network share

    - by Christoph
    How can I reset the ACLs on a ZFS file system on OpenIndiana that is exported via NFS4 and replace it with inherited permissions? Basically, I want to do the equivalent of icacls "C:\path\to\folder" /reset /T /C on Windows on this machine. However, neither the chmod command on OpenIndiana nor the nfs4_setacl seems to allow for deleting all ACLs although the client correctly interprets inherited ACLs if a node does not have an own one.

  • Rsync: windows 7, synology: login error and permission denied error

    - by loonboon
    Good day to all of you all, I'm running into strange/stupid errors, and I hope anybody would be so kind to help me out. I have to admit, I am by no means a guru, so please bear with me :-) Situation: -Synology NAS (runs Linux), and Windows 7 desktop (1 normal/restricted user Lisa and 1 admin user). - Data from W7 desktop to be rsynced to synology: /volume1/home/Lisa/Backup - Rsync command: c:\cygwin\bin\rsync -avz /cygdrive/e/Lisa/ [email protected]:/volume1/homes/Lisa/Backup - I've set up ssh per these two threads: a. http://www.cesareriva.com/archives/102 b. http://www.cesareriva.com/archives/112 Now the horrors begin: - root is allowed to run the rsync succesfully, however, he doesn't login automatically (so I can not use rsync in W7 batchscripts, which is of course required). - Lisa is allowed to login automatically but he can not succesfully finish the rsync command because of permission errors: rsync change dir /volume1/homes/Lisa/Backup failed: permissions denied. This happens for each and every file and subdir rsync tries to create. However, the main directory (Backup) is created. When I try to copy files from windows explorer to the directory 'Backup' using the very same user Lisa everything goes smoothly. So, obviously, there is a permission problem somewhere; either my rsync-command isn't correct, or the folder permissions for homes/Lisa aren't correct (but, then again, Windows 7 copies files to that folder without any problems, so that does make me believe the homes/Lisa-permissions don't appear to be the problem). I also tried adding: --chmod=Dugo+x --chmod=ugo+r which I found somewhere on the web, to the rsync-command, but this didn't solve any problem and gave the exact errors. Would anybody please please help me on how to fix this? I am utterly frustrated about this, because I have been trying for 1 month to get everything to work and it simply doesn't work. I bought the big Synology to end the horrors of 20 external USB-disks for once and for all (we have many pictures and home vids of our deceased dogs and want to watch these, the horrors being 'what material is on what disk'). I'll gladly return the favour of somebody helping me out by buying you a nice beer (paypal), if you could end my misery. I am not extremely skilled on Linux (not at all :-( ) so if you could give an extra word when possible so I understand what to do, I'd be very grateful. I really hope somebody can help me out, Thank you in advance, Lisa

  • Monitor uSWGI via Nagios: invalid socket

    - by webjay
    I'm trying to monitor uSWGI via Nagios, but according to uWSGI I have specified an invalid socket. The socket path I got from the JSON config file which also says chmod-socket: 666 so I have a hunch that the problem is permission based. The socket file is owned by www-data who I don't want to tinker with, so any other ways? uwsgi --socket=/tmp/app.sock --nagios detected binary path: /usr/local/bin/uwsgi UWSGI UNKNOWN: you have specified an invalid socket ls -l /tmp/app.sock srw-rw-rw- 1 www-data www-data 0 2012-10-26 17:00 /tmp/app.sock

    - by josef.van.niekerk
    I am trying to do the following on my Mac (10.6.7) : sudo chown myusername:wheel ./entries but Unix/Mac is returning "Operation not permitted". When I ls -lash, the culprit file, it looks as follows: 8 -rwxrwxrwx 1 myusername staff 394B Apr 26 23:26 entries I've tried sudo, I've tried sudo su, nothing works? Any ideas what's up?

  • Execute a script with root permission

    - by Bastien974
    Hi all, I need a script that will chown/chmod some files. This script need to be executable by any user. The problem is that those files are owned by different users, so it needs to be executed as root. I tried the SUID so that any users with X permission can execute the script as root, but seems that it doesn't work with a bash script because of security issue. How can I do that ? thanks.
