  • Samba network sharing NTFS drives and root permissions from local drives

    - by Bill
    I'm able to share my internal 2ndry NTFS drives (sdb1,2 and 3) on the network with Windows computers now but even though Samba read/write is enabled, Windows network computers can only open files "read-only" and can't save files to the samba shared drives/folders. I try to set permissions in Ubuntu via folder and/or file properties even logged in root via Nautilus but all the samba shared folders and files are set as owner = root, accessible and does not allow me to change them to read/write, it just resets to root, accessible, in other words, I can't change permissions. I'm running Ubuntu 11.04 Gnome on an old Dell Dimension 2400. Also, in order to for me to copy or move any files from the Ubuntu drive to the sdb1,2 or 3 drives, I have to gksu nautilus. This consequently prevents me from copying .ISO files to my "Multisys" thumb drive too.

  • Give permissions for packages downloaded from the internet and lock them in Ubuntu 12.04 sidebar

    - by JuninhoDG
    I downloaded NetBeans IDE and Eclipse IDE from the internet and installed then. Well, the Eclipse IDE works fine, but when I execute NetBeans IDE directly from the link, without sudo permission, it shows me lots of error telling that some files are read only. This does not happens when I'm using the terminal to call the .sh script with sudo permissions. Another thing that bothers me: How can I fix my shortcuts in the Ubuntu's 12.04 sidebar? I want to combine a launcher with enough permissions to do everything it's needing and fix it in my sidebar. Is it possible?

  • Permissions depending on parameters passed to application

    - by Engineiro
    I have a java app that writes to a very important table I have. This is sudo protected, but this app takes a parameters for where the output should go. The default is the REAL DEAL but the "output" parameter takes priority over the default, so if a user provides a path that they have write permission for, say: /home/username/mystuff then I would like for users to be allowed to write to these directories. The app is launched in a shell script, so I am wondering if I can check that the string does not equal /path/to/real/deal and not empty (since /path/to/real/deal is the default) and allow users to write to places they have permissions for. My impression of linux permissions is that it is tied to the application itself and cannot be conditionally approved, but I wonder if there is some bash fu or alternative method I can perform to get me my desired result. Using Ubuntu 10.04.4 LTS

  • Permissions scheme not working

    - by ReaZem
    I am currently building a home server and I am trying to give minimal permissions to every service. I am new to permissions management and this is an awesome learning experience for me :). drwxr----- 7 reazem enter-home 4096 Sep 9 21:43 reazem drwxrws--- 3 reazem minidlna 4096 Sep 9 21:36 media reazem is my home folder and media is my media folder, it is situated directly inside my home. The minidlna user is part of the following groups : minidlna, enter-home. I get the following error: Media directory not accessible! [/home/reazem/media] I was hoping that because the minidlna user is part of the enter-home group, it could get inside the home folder, and then inside the media folder because it is in the minidlna group. Where is my mistake? Edit: I found out that chmod g+x /home/reazem solved the problem, but why? Why would you need the execute permission to get inside another directory? Thank you!

  • Setting up fastcgi on an Ubunutu server (socket file permissions issue)

    - by gray alien
    I am trying to set up mod_fcgid on my server. Part of the requirement is that Apache needs to create a socket file for mod_fcgid. I specified the folder for Apache to write the socket data to: /var/run/apache2/fcgid I then specified this file in my fcgid.conf file as follows: SocketPath /var/run/apache2/fcgid/sock I then changed the owner of the folder to www-data (the apache user) and gave the owner full permissions to the folder and its contents. I was able to run my test fcgi app then. When I rebooted the machine, y fastcgi app no longer worked. After some investigation, I found that ownership of /var/run/apache2/fcgid has been reset to root, and with permission reset to 700 I have the following questions: Is there something specific about the /var/run folder? why is the permissions being reset after a reboot? Should I move my socket file to another location (in case root automatically takes ownership of contents in this folder for security reasons?) I am running Ubuntu 10.0.4 LTS 64 bit

  • node.js / socket.io, cookies only working locally

    - by Ben Griffiths
    I'm trying to use cookie based sessions, however it'll only work on the local machine, not over the network. If I remove the session related stuff, it will however work just great over the network... You'll have to forgive the lack of quality code here, I'm just starting out with node/socket etc etc, and finding any clear guides is tough going, so I'm in n00b territory right now. Basically this is so far hacked together from various snippets with about 10% understanding of what I'm actually doing... The error I see in Chrome is: socket.io.js:1632GET http://192.168.0.6:8080/socket.io/1/?t=1334431940273 500 (Internal Server Error) Socket.handshake ------- socket.io.js:1632 Socket.connect ------- socket.io.js:1671 Socket ------- socket.io.js:1530 io.connect ------- socket.io.js:91 (anonymous function) ------- /socket-test/:9 jQuery.extend.ready ------- jquery.js:438 And in the console for the server I see: debug - served static content /socket.io.js debug - authorized warn - handshake error No cookie My server is: var express = require('express') , app = express.createServer() , io = require('socket.io').listen(app) , connect = require('express/node_modules/connect') , parseCookie = connect.utils.parseCookie , RedisStore = require('connect-redis')(express) , sessionStore = new RedisStore(); app.listen(8080, '192.168.0.6'); app.configure(function() { app.use(express.cookieParser()); app.use(express.session( { secret: 'YOURSOOPERSEKRITKEY', store: sessionStore })); }); io.configure(function() { io.set('authorization', function(data, callback) { if(data.headers.cookie) { var cookie = parseCookie(data.headers.cookie); sessionStore.get(cookie['connect.sid'], function(err, session) { if(err || !session) { callback('Error', false); } else { data.session = session; callback(null, true); } }); } else { callback('No cookie', false); } }); }); var users_count = 0; io.sockets.on('connection', function (socket) { console.log('New Connection'); var session = socket.handshake.session; ++users_count; io.sockets.emit('users_count', users_count); socket.on('something', function(data) { io.sockets.emit('doing_something', data['data']); }); socket.on('disconnect', function() { --users_count; io.sockets.emit('users_count', users_count); }); }); My page JS is: jQuery(function($){ var socket = io.connect('http://192.168.0.6', { port: 8080 } ); socket.on('users_count', function(data) { $('#client_count').text(data); }); socket.on('doing_something', function(data) { if(data == '') { window.setTimeout(function() { $('#target').text(data); }, 3000); } else { $('#target').text(data); } }); $('#textbox').keydown(function() { socket.emit('something', { data: 'typing' }); }); $('#textbox').keyup(function() { socket.emit('something', { data: '' }); }); });

  • Windows 7 Sharing issue on RAID 5 Array(s)

    - by K.A.I.N
    Greetings all, I'm having a very odd error with a windows 7 ultimate x64 system. The network system setup is as follows: 2x XP Pro 32 Bit machines 1x Vista ultimate x64 machine 2x Windows 7 x64 Ultimate machines all chained into 1x 16 port netgear prosafe gigabit switch, the windows 7 & vista machines are duplexed. Also there is a router (netgear Rangemax) chained off the switch I am basically using one of the windows 7 machines to host storage & stream media to other machines. To this end i have put 2x 3tb hardware RAID 5 arrays in it and assorted other spare disks which i have shared the roots of. The unusual problems start when i am getting Access denied, Please contact administrator for permission blah blah blah when trying to access both of the RAID 5 arrays but not the other stand alones. I have checked the permission settings, i have added everyone to the read permission for the root, i have tried moving things into sub directories then sharing them. I have tried various setting combinations in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa and always the same. I have tried flushing caches all round, disabling and re-enabling shares & sharing after restart as well as several other things & the result is always the same... No problem on individual drives but access denied on both the RAID arrays from both XP & Vista & Windows 7 machines. One interesting quirk that may lead to an answer is that there is no "offline status" information regarding the folders when you select the RAID 5s from a windows 7 machine yet there is on the normal drives which say they are online. It is as if the raid is present but turned off or spun down but as far as i was aware windows will spin an array back up on network request and on the machine itself the drives seem to be online and can be accessed. Have to admit this has me stumped. Any suggestions anyone? Thanks in advance for any fellow geek assistance. K.A.I.N

  • Samba Server Make Multiple User Permissions Profiles

    - by Scriptonaut
    I have a Samba file server running, and I was wondering how I could make multiple user accounts that have different permissions. For example, at the moment I have a user, smbusr, but when I ssh to the share, I can read, write, execute, and even navigate out of the samba directory and do stuff on the actual computer. This is bad because I want to be able to give out my IP so friends/family can use the server, but I don't want them to be able to do just anything. I want to lock the user in the samba share directory(and all the sub directories). Eventually I would like several profiles such as (smbusr_R, smbusr_RW, smbguest_R, smbguest_RW). I also have a second question related to this, is SSH the best method to connect from other unix machines? What about VPN? Or simply mounting like this: mount -t ext3 -o user=username //ipaddr/share /mnt/mountpoint Is that mounting command above the same thing as a vpn? This is really confusing me. Thanks for the help guys, let me know if you need to see any files, or need anymore information.

  • Unix Permissions: Enable access to files no matter the user?

    - by TK Kocheran
    I've been using Linux for a long time and I still am completely in the dark about how file permissions really work. With that in mind, does anyone have any books or thorough guides I could read to really understand things completely? I've done my fair share of sysadminning, so I know the easy stuff like making directories readable and writable, making files executable, and changing the owner of a file, but on sharing files across users, I'm lost. Here's my main problem. I have a number of machines across which I intend to synchronize my music library. I've been using Unison for a while now and it's a great choice as I can easily run it over SSH on my local network which I just set up. Win-win. Up until this point, I've been synchronizing computers using a 2TB external hard drive. (computer 1 unisons to HD, computer 2 unisons to HD, etc.) This is tedious at best, especially since I encrypted the drive, making it a huge hassle to hook it up to all of my machines and sync it. Anyway, the drive is running ext4 (in TrueCrypt), so it maintains all Unix filesystem info like owners and groups. I just set up a new machine and just Unison'd it to get the music on it, and I realized that now, all of my permissions are fubar. I had to run Unison as root since that was the only way I could get the files to come off of the external drive. Apparently, since I'm using a different user name on this machine than my usual "rfkrocktk" across all machines, this essentially throws a huge wrench in the gears. Here's my use case. This laptop has two effective users, "leandra" and "rfkrocktk". I want to share music between these two users, so I symlinked /home/rfkrocktk/Music to point to /home/leandra/Music. How do I (a) allow both users access to read/write/delete files in this folder, and (b) keep everything nicely in sync without messing up file ownership?

  • Media Drive Permissions

    - by Wade Wofford
    I just switched from a Hackintosh to Linux, and am trying to make sense of it. On my hackintosh, I partitioned a big drive into 3 parts--1 which holds music, 1 for film/tv, and one for the OS. I installed Ubuntu onto the OS partition, and am now trying to make it so I can write to the media drives. I've searched around and tried several things. I tried gksu nautilus in Terminal, which brought me into root permissions. When I select a folder and try to change permissions, I get "The owner could not be changed...Error setting owner: Read-only file system" Ultimately, I have two specific aims: - I want to make it so I can write to the film/tv drive from the ubuntu machine only - I want to make it so I can write to the music drive from the ubuntu machine, or any other machine on the network (all Macs). That is, I want a single music library (an iTunes file) that will serve all Mac laptops/iPads/iPhones on the network, but which XBMC on the Ubuntu machine can also see / read from. Music will be added to the iTunes library via a single Mac laptop, but all other devices should be able to see the music drive.

  • Insufficient permissions when calling flickr.auth.oauth.checkToken

    - by Designer 17
    This is a follow up on another question I had asked on stackoverflow a day or so ago. I'm working on trying to call flickr.people.getPhotos... but no matter what I do I keep getting this... jsonFlickrApi({"stat":"fail", "code":99, "message":"Insufficient permissions. Method requires read privileges; none granted."}); but if you were to look at my "Apps You're Using" page (on flickr) you'd see this. So, even though I've authorized the max permissions... flickr says I don't have any granted!? I even used flickr.auth.oauth.checkToken to double check that my access token was right, this was the value returned; jsonFlickrApi({"oauth":{"token":{"_content":"my-access-token"}, "perms":{"_content":"delete"}, "user":{"nsid":"my-user-nsid", "username":"designerseventeen", "fullname":"Designer Seventeen"}}, "stat":"ok"}) Here's how I'm attempting to call flickr.people.getPhotos... <?php // Attempt to call flickr.people.getPhotos $method = "flickr.people.getPhotos"; $format = 'json'; $nsid = 'my-user-nsid'; $sig_string = "{$api_secret}api_key{$api_key}format{$format}method{$method}user_id{$nsid}"; $api_sig = md5( $sig_string ); $flickr_call = "http://api.flickr.com/services/rest/?"; $url = "method=" . $method; $url .= "&api_key=" . $api_key; $url .= "&user_id=" . $nsid; $url .= "&format=" . $format; $url .= "&api_sig=" . $api_sig; $url = $flickr_call . $url; $results = file_get_contents( $url ); $rsp_arr = explode( '&',$results ); print "<pre>"; print_r($rsp_arr); print "</pre>"; I am officially stumped... and in need of help.

  • Handling permissions in a MVP application

    - by Chathuranga
    In a windows forms payroll application employing MVP pattern (for a small scale client) I'm planing user permission handling as follows (permission based) as basically its implementation should be less complicated and straight forward. NOTE : System could be simultaneously used by few users (maximum 3) and the database is at the server side. This is my UserModel. Each user has a list of permissions given for them. class User { string UserID { get; set; } string Name { get; set; } string NIC {get;set;} string Designation { get; set; } string PassWord { get; set; } List <string> PermissionList = new List<string>(); bool status { get; set; } DateTime EnteredDate { get; set; } } When user login to the system it will keep the current user in memory. For example in BankAccountDetailEntering view I control the controller permission as follows. public partial class BankAccountDetailEntering : Form { bool AccountEditable {get; set;} private void BankAccountDetailEntering_Load(object sender, EventArgs e) { cmdEditAccount.enabled = false; OnLoadForm (sender, e); // Event fires... If (AccountEditable ) { cmdEditAccount.enabled=true; } } } In this purpose my all relevant presenters (like BankAccountDetailPresenter) should aware of UserModel as well in addition to the corresponding business Model it is presenting to the View. class BankAccountDetailPresenter { BankAccountDetailEntering _View; BankAccount _Model; User _UserModel; DataService _DataService; BankAccountDetailPresenter( BankAccountDetailEntering view, BankAccount model, User userModel, DataService dataService ) { _View=view; _Model = model; _UserModel = userModel; _DataService = dataService; WireUpEvents(); } private void WireUpEvents() { _View.OnLoadForm += new EventHandler(_View_OnLoadForm); } private void _View_OnLoadForm(Object sender, EventArgs e) { foreach(string s in _UserModel.PermissionList) { If( s =="CanEditAccount") { _View.AccountEditable =true; return; } } } public Show() { _View.ShowDialog(); } } So I'm handling the user permissions in the presenter iterating through the list. Should this be performed in the Presenter or View? Any other more promising ways to do this? Thanks.

  • What permissions are required for SET IDENTITY_INSERT ON?

    - by AaronBertrand
    SQL Server 2000's SET IDENTITY_INSERT ON topic says: Execute permissions default to the sysadmin fixed server role, and the db_owner and db_ddladmin fixed database roles, and the object owner. While the SET IDENTITY_INSERT topic for SQL Server 2005 (and up) says: User must own the object, or be a member of the sysadmin fixed server role, or the db_owner and db_ddladmin fixed database roles. This was clearly adapted from the 2000 books online and re-written by someone who misinterpreted "db_owner...(read more)

  • Correct permissions for /var/www and wordpress

    - by dpbklyn
    Hello and thank you in advance! I am relatively new to ubuntu, so please excuse the newbie-ness of this question... I have set up a LAMP server (ubuntu server 11.10) and I have access via SSH and to the "it works" page from a web browser from inside my network (via ip address) and from outside using dyndns. I have a couple of projects in development with some outside developers and I want to use this server as a development server for testing and for client approvals. We have some Wordpress projects that sit in subdirectories in /var/www/wordpress1 /var/www/wordpress2, etc. I cannot access these sub directories from a browser in order to set up WP--or (I assume) to see the content on a browser. I get a 403 Forbidden error on my browser. I assume that this is a permissions problem. Can you please tell me the proper settings for the permissions to: 1) Allow the developers and me to read/write. 2) to allow WP set up and do its thing 3) Allow visitors to access the site(s) via the web. I should also mention that the subfolder are actually simlinks to folder on another internal hdd--I don't think this will make a difference, but I thought I should disclose. Since I am a newbie to ubuntu, step-by-step directions are greatly appreciated! Thank you for taking the time! dp total 12 drwxr-xr-x 2 root root 4096 2012-07-12 10:55 . drwxr-xr-x 13 root root 4096 2012-07-11 20:02 .. lrwxrwxrwx 1 root root 43 2012-07-11 20:45 admin_media -> /root/django_src/django/contrib/admin/media -rw-r--r-- 1 root root 177 2012-07-11 17:50 index.html lrwxrwxrwx 1 root root 14 2012-07-11 20:42 media -> /hdd/web/media lrwxrwxrwx 1 root root 18 2012-07-12 10:55 wordpress -> /hdd/web/wordpress Here is the result of using chown -R www-data:www-data /var/www total 12 drwxr-xr-x 2 www-data www-data 4096 2012-07-12 10:55 . drwxr-xr-x 13 root root 4096 2012-07-11 20:02 .. lrwxrwxrwx 1 www-data www-data 43 2012-07-11 20:45 admin_media -> /root/django_src/django/contrib/admin/media -rw-r--r-- 1 www-data www-data 177 2012-07-11 17:50 index.html lrwxrwxrwx 1 www-data www-data 14 2012-07-11 20:42 media -> /hdd/web/media lrwxrwxrwx 1 www-data www-data 18 2012-07-12 10:55 wordpress -> /hdd/web/wordpress I am still unable to access via browser...

  • Help recovering broken OS (permissions issue)

    - by Guandalino
    (At the bottom there is an important update.) I was doing experiments in order to backup a remote account to my local system, Ubuntu 12.04 LTS. I'm not confident with duplicity and probably, due to wrong syntax, some local files have been replaced with remote files. This is just a supposition, I'm not sure this is the real cause of OS corruption. The corruption happened after experimenting with backups, so I think I did something wrong at this regard. I was aware there was a problem when I tried to access a command using sudo: $ sudo ls sudo: unable to open /etc/sudoers: Permission denied sudo: no valid sudoers sources found, quitting sudo: unable to initialize policy plugin This is how /etc/sudoers looks like: $ ls -ald /etc/sudoers -r--r----- 1 root root 788 Oct 2 18:30 /etc/sudoers At this point I tried to reboot and now this is the message I get: The system is running in low graphics mode. Your screen, graphics card and input device settings could not be detected correctly. You will need to configure these yourself. I tried to follow the wizard to configure these settings, but without luck (the system prevents me going on when I press "Next"). The thing that makes me a bit less worried is that all the data on the disk seems readable and I'm able to access them using a live cd. I run memtest and RAM seems to be OK. Do you have any idea about how to recover my system? I'm very glad to provide further information, just let me know what info could be helpful. UPDATE. The issue is about wrong permissions and this is how I discovered: I mounted the root partition of the broken OS on /mnt/broken/ (live CD) and did ls /mnt/broken/. I got a permission denied error, while I expected to have the directory listing. I had to do sudo ls /mnt/broken/ and this worked. Thus without having root permission via sudo it's impossible to access the root of broken os. The current output of ls -ld /mnt/broken/ is: drwxr-x--- 29 1000 812 4096 2012-12-08 21:58 /mnt/broken Any thoughts on how to restore the old (working) set of permissions?

  • Can't copy files with 'additional permissions' to ext4 drive -- files that have @ after permissions,

    - by 99miles
    I am copying files from Snow Leopard to a mounted ext4 share via Samba, that's on a Fedora machine. Some files cannot be copied, and give this error: The operation can’t be completed because you don’t have permission to access some of the items. I've noticed that the files that can't be copied have an @ at the end of their permissions whien I do 'ls -l' in the command line. For example, I can copy the second file but not the first: -rwxrwxrwx@ 1 miles staff 1448 May 14 22:55 test.txt -rw-r--r-- 1 miles staff 136 Apr 5 17:06 image.psd.zip From what I've found, the @ means the file has 'additional properties'. Does anyone know how I can resolve this issue so I can copy the files to the fileshare?? Thanks!

  • Plesk file permissions - Apache/PHP conflicting with user accounts.

    - by hfidgen
    Hiya, I'm building a Drupal site which performs various automatic disk operations using the apache user (id=40). The problem is that the site was set up on a subdomain belonging to user ID 10001 (ie my main FTP account) so the filesystem belongs to that user ID. So I keep getting errors like this: warning: move_uploaded_file() [function.move-uploaded-file]: SAFE MODE Restriction in effect. The script whose uid is 10001 is not allowed to access /var/www/vhosts/domain.com/httpdocs/sites/default/files/images/user owned by uid 48 in /var/www/vhosts/domain.com/httpdocs/includes/file.inc on line 579. I've tried changing the apache group in httpd.conf to apache:psacln, psacln being the default group for all web users but that's not helped. The situation now is: ..../files/images/ = 777 and chown = ftplogin:psacln ..../files/images/user = 775 and chown = apache:psacln ..../files/tmp = 777 and chown = ftplogin:psacln So apparently uid 40 and 10001 both have permissions to write to any of the 3 directories involved, but still can't. Am i missing something here? Can anyone help? Thanks!

  • SAMBA and Linux ACLs -- "Permission denied" on write to share but file written nevertheless

    I set up a writable share directory "/home/net/share" with acl like this: sudo mkdir -p "/home/net/share" sudo setfacl -m "u:localuser:rwx,u:remoteuser:rwx,g:users:rwx" "/home/net/share" My /etc/samba/smb.conf looks like this: [global] workgroup = w server string = server security = user load printers = no log file = /var/log/samba/%m.log max log size = 50 dns proxy = no printing = bsd printcap name = /dev/null disable spoolss = yes encrypt passwords = true invalid users = nobody root follow symlinks = yes wide links = yes [share] comment = Writable by localuser and remoteuser path = /home/net/share valid users = remoteuser read only = no public = no printable = no Locally, localuser and remoteuser have user accounts and smbpasswds and can both read, create and delete files in /home/net/share. But when I log on from a different machine (like this: sudo mount -t cifs //server/share mountpoint/ -o username=remoteuser ), I get "Permission denied" both when trying to create directories and files, oddly though, it does create files (not directories!) despite these messages! How can I get this working?

  • File permissions question

    - by Camran
    If I need a php-page to have access to upload images and move images from a folder on the server, what permissions would I set on the folder then? I know we have "Owner", "Group", and "Others". But what does the server (or the php-code itself) count as? Owner? Also, would I need to set the php-page with the upload script with some specific permissions to be able to upload the files? Is it execute permissions? Thanks

  • CentOS 5.4 NFS v4 client file permissions differ from original files & NFS Share file contents

    - by p4guru
    Having a strange problem with NFS share and file permissions on the 1 out of the 2 NFS clients, web1 has file permissions issues but web2 is fine. web1 and web2 are load balanced web servers. So questions are: how do I ensure NFS share file contents retain the same permissions for user/group as the original files on web1 server like they do on web2 server ? how do I reverse what I did on web1, i tried unmount command and said command not found ? Information: I'm using 3 dedicated server setup. All 3 servers CentOS 5.4 64bit based. servers are as follows: web1 - nfs client with file permissions issues web2 - nfs client file permissions are OKAY db1 - nfs share at /nfsroot web2 nfs client was setup by my web host, while web1 was setup by me. I did the following commands on web1 and it worked with updating db1 nfsroot share at /nfsroot/site_css with latest files on web1 but the file permissions don't stick even if i use tar with -p command to perserve file permissions ? cd /home/username/public_html/forums/script/ tar -zcp site_css/ > site_css.tar.gz mount -t nfs4 nfsshareipaddress:/site_css /home/username/public_html/forums/scripts/site_css/ -o rw,soft cd /home/username/public_html/forums/script/ tar -zxf site_css.tar.gz But checking on web1 file permissions no longer username user/group but owned by nobody ? but web2 file permissions correct ? This is only a problem for web1 while web2 is correct ? Looks like numeric ids aren't the same ? Not sure how to correct this ? web1 with incorrect user/group of nobody ls -alh /home/username/public_html/forums/scripts/site_css total 48K drwxrwxrwx 2 nobody nobody 4.0K Feb 22 02:37 ./ drwxr-xr-x 3 username username 4.0K Feb 22 02:43 ../ -rw-r--r-- 1 nobody nobody 1 Nov 30 2006 index.html -rw-r--r-- 1 nobody nobody 5.8K Feb 22 02:37 style-057c3df0-00011.css -rw-r--r-- 1 nobody nobody 5.8K Feb 22 02:37 style-95001864-00002.css -rw-r--r-- 1 nobody nobody 5.8K Feb 18 05:37 style-b1879ba7-00002.css -rw-r--r-- 1 nobody nobody 5.8K Feb 18 05:37 style-cc2f96c9-00011.css web1 numeric ids ls -n /home/username/public_html/forums/scripts/site_css total 48 drwxrwxrwx 2 99 99 4096 Feb 22 02:37 ./ drwxr-xr-x 3 503 500 4096 Feb 22 02:43 ../ -rw-r--r-- 1 99 99 1 Nov 30 2006 index.html -rw-r--r-- 1 99 99 5876 Feb 22 02:37 style-057c3df0-00011.css -rw-r--r-- 1 99 99 5877 Feb 22 02:37 style-95001864-00002.css -rw-r--r-- 1 99 99 5877 Feb 18 05:37 style-b1879ba7-00002.css -rw-r--r-- 1 99 99 5876 Feb 18 05:37 style-cc2f96c9-00011.css web2 correct username user/group permissions ls -alh /home/username/public_html/forums/scripts/site_css total 48K drwxrwxrwx 2 root root 4.0K Feb 22 02:37 ./ drwxr-xr-x 3 username username 4.0K Dec 2 14:51 ../ -rw-r--r-- 1 username username 1 Nov 30 2006 index.html -rw-r--r-- 1 username username 5.8K Feb 22 02:37 style-057c3df0-00011.css -rw-r--r-- 1 username username 5.8K Feb 22 02:37 style-95001864-00002.css -rw-r--r-- 1 username username 5.8K Feb 18 05:37 style-b1879ba7-00002.css -rw-r--r-- 1 username username 5.8K Feb 18 05:37 style-cc2f96c9-00011.css web2 numeric ids ls -n /home/username/public_html/forums/scripts/site_css total 48 drwxrwxrwx 2 503 500 4096 Feb 22 02:37 ./ drwxr-xr-x 3 503 500 4096 Dec 2 14:51 ../ -rw-r--r-- 1 503 500 1 Nov 30 2006 index.html -rw-r--r-- 1 503 500 5876 Feb 22 02:37 style-057c3df0-00011.css -rw-r--r-- 1 503 500 5877 Feb 22 02:37 style-95001864-00002.css -rw-r--r-- 1 503 500 5877 Feb 18 05:37 style-b1879ba7-00002.css -rw-r--r-- 1 503 500 5876 Feb 18 05:37 style-cc2f96c9-00011.css I checked db1 /nfsroot/site_css and user/group ownership was incorrect for newer files dated feb22 owned by root and not username ? on db1 originally incorrect root assigned user/group for new feb22 dated files ls -alh /nfsroot/site_css total 44K drwxrwxrwx 2 root root 4.0K Feb 22 02:37 . drwxr-xr-x 17 root root 4.0K Feb 17 12:06 .. -rw-r--r-- 1 root root 1 Nov 30 2006 index.html -rw-r--r-- 1 root root 5.8K Feb 22 02:37 style-057c3df0-00011.css -rw-r--r-- 1 root root 5.8K Feb 22 02:37 style-95001864-00002.css -rw------- 1 username nfs 5.8K Feb 18 05:37 style-b1879ba7-00002.css -rw------- 1 username nfs 5.8K Feb 18 05:37 style-cc2f96c9-00011.css Then I chmod them all on db1 and chown to set to right ownership on db1 so it looks like below on db1 once corrected the newer feb22 dated files ls -alh /nfsroot/site_css total 44K drwxrwxrwx 2 root root 4.0K Feb 22 02:37 . drwxr-xr-x 17 root root 4.0K Feb 17 12:06 .. -rw-r--r-- 1 username username 1 Nov 30 2006 index.html -rw-r--r-- 1 username username 5.8K Feb 22 02:37 style-057c3df0-00011.css -rw-r--r-- 1 username username 5.8K Feb 22 02:37 style-95001864-00002.css -rw-r--r-- 1 username username 5.8K Feb 18 05:37 style-b1879ba7-00002.css -rw-r--r-- 1 username username 5.8K Feb 18 05:37 style-cc2f96c9-00011.css but still web1 shows owned by nobody ? while web2 shows correct permissions ? web1 still with incorrect user/group of nobody not matching what web2 and db1 are set to ? ls -alh /home/username/public_html/forums/scripts/site_css total 48K drwxrwxrwx 2 nobody nobody 4.0K Feb 22 02:37 ./ drwxr-xr-x 3 username username 4.0K Feb 22 02:43 ../ -rw-r--r-- 1 nobody nobody 1 Nov 30 2006 index.html -rw-r--r-- 1 nobody nobody 5.8K Feb 22 02:37 style-057c3df0-00011.css -rw-r--r-- 1 nobody nobody 5.8K Feb 22 02:37 style-95001864-00002.css -rw-r--r-- 1 nobody nobody 5.8K Feb 18 05:37 style-b1879ba7-00002.css -rw-r--r-- 1 nobody nobody 5.8K Feb 18 05:37 style-cc2f96c9-00011.css Just so confusing so any help is very very much appreciated! thanks
